RE: Letter of TransmittalBaseline Risk AssessmentAmerican Chemical Services NPL SiteProject # 60251

Dear Mr. Hartwick:

Enclosed is a copy of the Baseline Risk Assessment for the ACS NPL Site.It has been revised in accordance with the U.S. EPA comments datedAugust 19, 1991 and August 28, 1991.

The document does not .contain section 7.2, the Ecological Assessment. Wehave not been able to respond to all the Biological Team Assessment Group(BTAG)-comments, partly because the AQUIRE database is not yetavailable from NTIS.

I discussed this difficulty with you in a telephone conversation on September18, 1991. You agreed that we should submit just the completed section, theBaseline Risk Assessment, and submit the 'Ecological Assessment after wehave been able to obtain the necessary information.

We discussed setting up a conference call between BTAG and Warzyn assoon as possible to resolve the data issues. One of the quickest solutionswould be if BTAG could provide the necessaiy information directly to us.

Sincerely yours,

WARZYN INC.

SECTION 7.0

BASELINE RISK ASSESSMENT

7.1 HUMAN HEALTH EVALUATION

7.1.1 Introduction

Section 300.430 of the National Oil and Hazardous Substances Pollution Contingency

Plan (NCP 1990) states that the purpose of the remedial process for a contaminated

site is to implement remedies that reduce, control, or eliminate risks to human health

and the environment. The mandate of the Superfund program is to protect human

health and the environment from current and potential substance releases, as enforced

in the NCP.

Under CERCLA and the Superfund process, a Baseline Risk Assessment is the vehicle

or tool which may be used to evaluate the potential threats to public health and the

environment from a site in the absence of any remedial action (U.S. EPA, 1988). It

identifies and characterizes the lexicological characteristics of the contaminants of

concern, the potential exposure pathways, the potential human and environmental

receptors, and the potential health impact the site may pose. The information

obtained through risk assessment is used to assist in the evaluation of possible remedial

measures to reduce risk at a site.

This Baseline Risk Assessment addresses the potential risks associated with the

American Chemical Services Site (Site) under the "no-action" alternative. The no-

action alternative assumes that no corrective actions will take place and no restrictionswill be placed on future use of the Site.

The Baseline Risk Assessment for the Site was performed consistent with the Risk

Assessment Guidance for Superfund (RAGS, U.S. EPA, 1989). In addition, guidance

recommended in RAGS for conducting specific parts of the risk assessment were usedto the extent practicable.

Remedial Investigation ReportACS NPL Site, Griffith, Indiana Page 2Revision: DRAFT . , 20-SEPTEMBER-91

The Baseline Risk Assessment is based on the following major assumptions:

• No corrective actions will take place and no restrictions will be placed onfuture use of the Site.

• There are no groundwater use restrictions.

• There is the potential for future development of the Site.

• Contaminant concentrations in various media are assumed not to changeover time.

7.1.1.1 Organization

The Baseline Risk Assessment is organized into the following sections:

• Identification of Chemicals of Potential Concern

• Toxicity Assessment

• Exposure Assessment

• Risk Characterization

Identification of Chemicals of Potential Concern - This component consists of a reviewof the data collected during the remedial investigation at the Site in view of data

validity, chemical concentrations, media in which the chemicals have been detected,

frequency of chemical detection, the toxic properties of the chemicals, the physical

properties of each chemical as they relate to fate and migration potential, and the

conditions of potential exposure to identified human receptors.

Toxicity Assessment - The toxicity assessment is a determination of the quantitativeand qualitative relationship between the magnitude of exposure to chemicals ofpotential concern at the Site and the probability of occurrence of adverse health effects

from that exposure.

Exposure Assessment - This element of the Baseline Risk Assessment identifiespopulations .potentially exposed to Site contamination and evaluates the potentialmagnitude and duration of their exposure.

Risk Characterization - This final element integrates the toxicological information for

the chemicals of potential concern with potential exposure considerations to arrive atan estimate of public health risk.

Remedial Investigation ReportACS NPL Site, Griffith, Indiana • Page 3Revision: DRAFT 20-SEPTEMBER-91

7.1.1.2 Background

Previous sections of the Site Remedial Investigation (RI) Report provide descriptions

of the Site location, history, physical characteristics (i.e., geology, hydrogeology, etc.),

and sampling locations and media. Also included in previous sections is a discussion of

the Site chemistry as it relates to sample locations and chemical fate and migration.

Information presented in these previous sections has been used in the Baseline Risk

Assessment to assist in assessing public health risk. Reference to appropriate sections

of the RI Report should be made for detailed discussions of the background

information.

Because of the large area within the Site- RI/FS boundary, the numerous media

affected by contamination, and several discrete areas where contamination sources

exist, the Site was divided into nine operable areas (areas) including the Griffith

Municipal Landfill, for evaluation in the risk assessment. These areas are defined as

follows:/

• Groundwater - Upper Aquifer

• Groundwater - Lower Aquifer

• Surface Water

• Sediments

• On-Site Containment Area - Subsurface Contamination

• Still Bottoms and Treatment Lagoon - Subsurface Contamination• Off-Site Containment Area - Subsurface Contamination• Kapica-Pazmey Area - Surface and Subsurface Contamination• Griffith Municipal Landfill

t

These nine areas have been evaluated with respect to the contamination present at

each location. In defining these areas, potential exposure pathways and Feasibility

Study needs were taken into consideration. Table 7-1 provides a summary of samples

collected and analyzed for at each of the above areas.

Remedial Investigation ReportACS NPL Site, Griffith, Indiana Pace 4Revision: DRAFT 20-SEPTEMBER-91

7.1.2 Identification of Chemicals of Potential Concern

The identification of chemicals of potential concern at the Site involved a number of

steps. These steps, as outlined in the guidance, have been used to arrive at a list of

chemicals of potential concern which were subsequently evaluated in the Baseline Risk

Assessment.

7.1.2.1 Chemical Analysis of Site Media

After evaluating the quality/validity of data obtained from the performing Contract

Laboratory Program (CLP) laboratories, numerous chemicals were determined to be

present in various media at the Site. Twenty-seven Target Compound List (TCL)

volatiles were detected in various media as were 51 TCL semivolatiles, 14 TCL

pesticides/PCBs, more than 400 tentatively identified compounds (TIC), and the full

Target Analyte List (TAL) of metals. Tables 7-2 through 7-10 present the chemicals

detected in the designated source areas at the Site along with their respective

minimum, maximum, and arithmetic average concentrations, and frequency of

detection.

The chemical analyses of samples were performed through the CLP and have been

evaluated as to their usability in accordance with U.S. EPA guidance for validation of

organic and inorganic analyses of environmental samples (U.S. EPA, 1988a and b).

Data used in the present risk assessment include unqualified data and data which

represent estimated quantities (qualified J). For a description of the evaluation of

data quality, refer to Appendix Q of the RI Report.

7.1.2.2 Development of a Set of Chemical Data and Information for Use in the Risk

Assessment

The following describes the rationale for selection or exclusion of identified chemicals

in the data set as chemicals of potential concern for further evaluation in the risk

assessment. The process of identifying chemicals of potential concern and which

samples to include in the evaluation, is an integrated procedure.

As suggested in recent guidance, chemicals that exhibit the following characteristics are

to be included in a set of chemical data and information for use in the Baseline Risk

Assessment:

/ .1.*.Remedial Investigation Report 6he iiUAACS NPL Site, Griffith, Indiana Page 5Revision: DRAFT 20-SEPTEMBER- 91

\

• Positively detected in at least one CLP sample in a given medium. Positivelydetected chemicals include both unqualified results and results qualified asestimated but with known identities (J-qualified Target Compound Listdata);

/

• Determined to be present at the Site and not due to contaminationintroduced during sampling or analysis;

• Determined to be the result of chemical releases from the Site and notnatural background levels;

• Tentatively identified compounds associated with the Site; and

• Transformation products of chemicals demonstrated to be present.

The above criteria were applied to each of the areas defined earlier and for all

chemicals positively detected at the Site (refer to Appendix S for a detailed discussion

of the preceding approach and its application to each of the defined areas).

Because more than 400 tentatively identified compounds were detected at the Site, it

was necessary to group these chemicals based on similar chemical structure. Forty-four

groups were identified and a specific chemical was selected to represent each individual

group. Table 7-11 shows the chemical groups and Table 7-12 indicates the

representative chemical selected for each group and a brief description of the rationale

for the selection. When possible, the representative chemical was selected such that

the group's toxicity might be evaluated on the basis of a similar chemical with an

existing toxicity value. This approach was agreed upon by the U.S. EPA, Region V

Technical Support Group. The decision logic applied to the TTCs is illustrated in thedecision tree in Figure 7-1.

t

The result of the above processes culminated in most chemicals detected at the Site

being included in the risk assessment as chemicals of potential concern. The final list

of chemicals of potential concern based on the above criteria for each area are

presented in Table 7-13.

Remedial Investigation ReportACS NPL Site, Griffith, Indiana " Page 6Revision: DRAFT 20-SEPTEMBER-91

7.1.3 Exposure Assessment

The exposure assessment is performed to identify actual and potential pathways by

which human exposure to contaminated Site media might occur. The assessment

considers factors such as the physical location of contaminated areas, the type of

contamination, and the populations which may come into contact with these areas.

Exposure pathways are identified for two Site land-use scenarios: 1) pathways based on

land-use practices as they currently exist, and 2) potential pathways based on land-use

changes which may occur in the future and result in additional types of exposure.

Both current and future pathways which represent possible exposures were then

quantified in order to estimate the magnitude of daily contaminant exposure a

population may incur. To accomplish this, assumptions pertaining to the exposed

population were made such as, the nature of the individuals (as child vs. adult), the

rate of contact with the contaminated medium (e.g., adult consumes 2 liters of water

daily), and the length of time the exposure is likely to occur (e.g., years vs. lifetime).

These population variables are then integrated with chemical concentration data to

calculate a level of exposure (or dose).

7.1.3.1 Exposure Setting

7.1.3.1.1 Location of Site

The Site is located at and near 420 South Colfax Avenue in Griffith, Indiana. The Site

is located in the northeast one-quarter of the southeast one-quarter, Section 2,Township 35 North, Range 9 West, Lake County, Indiana (Figure 1-1). Although the

Site name is American Chemical Services (ACS), the U.S. EPA has defined the Site as

including the ACS property (19 acres), the Pazmey Corporation property (2 acres;

formerly Kapica Drum, Inc.), and the inactive portion of the Griffith Municipal

Landfill (about 15 acres).

The Site is bordered on the east and southeast by Colfax (Arbogast) Avenue. The

Chesapeake and Ohio Railroad right-of-way bisects the Site in a northwest-southeast

direction, between the fenced Site compound area and the off-site areas. On the west

and southwest, south of the Chesapeake and Ohio Railroad right-of-way, the Site is

bordered by the abandoned Erie and Lackawanna Railroad right-of-way, and the active

Remedial Investigation Report ' 6Ee i iUN /.l.jACS NPL Site, Griffith, Indiana Page 7Revision: DRAFT 20-SEPTEMBER-91

portion of the Griffith Municipal Landfill. North of the Chesapeake and Ohio right-

of-way, the Site is bordered on the west by wetland areas. The northern boundary of

the Site is formed by the Grand Trunk Railroad right-of-way.

7.1.3.1.2 Physical Setting

The Site is located in northwestern Indiana in the Calumet Lacustrine Plain, a

subdivision of the Northern Moraine and Lake Region of Hartke, et. al (1975). The

Calumet Lacustrine Plain represents a portion of the lake bed of glacial Lake Chicago.

The landscape is generally low-lying and exhibits little relief. In the immediate Site

vicinity, surface elevations range between 650 and 630 ft. MSL. The lower surface

elevations are associated with the wetlands located to the west and south of the Site,

while the higher elevations represent the relict sand dunes found east of the Site.

The geologic and hydrogeologic setting of the Site is presented in detail in Section 4 of

this report. In general, the geologic setting of the Site consists of approximately 130 ft

of unconsolidated glacial deposits overlying bedrock. Three geologic units have been

identified within the glacial deposits. These units are: an upper sand and gravel unit,

an intermediate silty clay unit, and a lower sand and gravel unit. Bedrock was not

encountered in any of the borings performed for the RI.

,The upper sand and gravel unit forms the uppermost aquifer at the Site. In the Site

monitoring wells, the thickness of this unit ranges from 13 to 32 ft, and averages 17 ft.

The upper aquifer exists under water table conditions at the Site, and is directlyinfluenced by precipitation patterns. Four dominant hydraulic controls have been

recognized for the uppermost aquifer. These controls include: (1) the regional

gradient, (2) discharge to drainage ditches, (3) dewatering activities at the active

landfill, and (4) recharge to the aquifer, which occurs mainly in the cleared and filled

areas. Potentiometric maps illustrating flow within the upper aquifer are presented in

Figures 4-17, 4-18, and 4-21.

Remedial Investigation Report bbLl iUN 7.1.JACS NPL Site, Griffith, Indiana Page 8Revision: DRAFT " 20-SEPTEMBER-91

The intermediate silty clay unit forms a confining layer between the upper aquifer and

the lower sand and gravel unit (lower aquifer). The silty clay ranges in thickness from

about 2.5 ft to 18 ft. This confining layer was found to be the thinnest in the

northwestern portion of the Site.

The full thickness of the lower sand and gravel unit (lower aquifer) was not penetrated

in any of the borings performed for the RI. Drillers' logs for water wells in the Site

vicinity indicate that the lower aquifer can be in excess of 50 ft thick. Based on

monitoring wells installed during the RI, the flow direction in the lower aquifer is to

the north.

Approximately 72 private wells were identified in the Site vicinity during the RI.

Figure 2-7 illustrates the location of the wells. Complete information on well depth

and aquifers screened were not available for all of the wells. The available information

has been summarized in Table 2-6 and Figure 2-7.

The majority of the private wells in the immediate Site vicinity which are used for

drinking water purposes are located to the east and northeast of the Site. These wells

draw water from the lower aquifer. Several wells in the upper aquifer were identified

near the Site, these wells are generally not used for drinking water supplies, but were

known to be used as drinking water supply wells as recently as five years ago by some

area residents located one-half mile north (upgradient) of the Site. Figure 4-13

illustrates the locations of the private wells identified near the Site with respect to theflow direction in the lower aquifer.

7.1.3.1.3 Zoning and Surrounding Land Uses

Zoning in the immediate vicinity of the Site is primarily industrial (Figure 7-2). The

areas adjacent to the Site on the north, east, and southeast are zoned either industrial

or light industrial. Areas to the west and southwest of the Site are zoned one-family

residential. No zoning changes are planned for the Site area.

In keeping with the current zoning, the following land uses are observed in the

immediate Site vicinity. In the following discussion, land uses are described in a clock-

wise fashion around the Site, beginning at the northeast corner.

>

Northeast of the intersection of Colfax Avenue and the Grand Trunk Railroad right-

of-way is a park, Oak Ridge Prairie. Immediately east of the Site fenced compound

and north of the Chesapeake and Ohio Railroad right-of-way, the land is undeveloped.

On the east side of Colfax Avenue and south of the Chesapeake and Ohio Railroad

right-of-way (east of the Off-Site Containment Area) are several small businesses,

including an auto repair shop, a welding shop, and a security dog business. East of

the Site, along the north side of Reder Road, are several single family residences.

Along the south side of Reder Road in this same area are several small businesses,

including a trucking firm, an auto repair shop, and an environmental clean-up

contracting firm. South of the intersection of Reder Road and Colfax Avenue

(Arbogast), on Arbogast, are a private residence and a small industrial building.

To the west and southwest of the Site, west of the abandoned Erie and Lackawanna

Railroad right-of-way, are vacant land and a residential development. The residential

area is separated from the Site by the active portions of the Griffith Municipal

Landfill.

North of the Grand Trunk Railroad right-of-way, along the northern boundary of the

Site, the land is primarily vacant. Further to the north, along Main Street, are small

businesses and an industrial park.

7.1.3.1.4 Distance to Nearest Receptors

The nearest residence to the Site is located at Reder Road, approximately 150 fteast of the Off-Site Containment Area. Other residences within about 500 ft of the

southeastern property boundary include Reder Road, Reder Road, 1043

Reder Road, and 945 South Arbogast. The nearest potential receptors east of the Site

are the employees of the businesses located approximately 100 to 200 ft east of the

Off-Site Containment Area, along the east side of Colfax Avenue. To the south and

west of the Site, the nearest potential receptors are the employees of the Griffith

Municipal Landfill, and the occupants of the residential development approximately

800 ft west of the Site boundary. To the north, the nearest potential receptors are

occupants of the industrial park and small businesses along Main Street (approximately

1000 to 2000 ft north of the Site boundary).

7.1.3.1.5 Population Information

The most recent census for which data was available on individual census tracts was the

1980 census. Based on 1980 census data (as of this writing, 1990 census data was not

available), 17,026 people live in the Town of Griffith. In the census tracts of other

communities within a two mile radius of the Site, 15,423 persons were identified in the

town of Highland, 18,149 in the town of Merrillville, 1,423 in the town of Schererville.

and 8,084 in unincorporated Lake County.

The median age of persons identified in the Griffith census tracts was 27.7 to 32.8

years. The median age in the Highland tracts bordering the Site area was 28 to 30.7

years. The median age in the Merrillville tract and the Schererville tract, respectively,

was 34.7 and 24.8 years. In the unincorporated areas of Lake County bordering the

Site, the median age was 30.1.

7.1.3.2 Exposure Pathway Analysis

A chemical exposure pathway describes the route taken by a chemical from its source

in the environment, to contact with receptors. As such, each exposure pathway must

include the following elements:

• A source and mechanism of chemical release to the environment;/

• An environmental transport medium (e.g., air, groundwater) for the releasedchemical;

• A point of potential human contact with the contaminated medium (referredto as the exposure point); and

• Receptor contact (e.g., ingestion of contaminated groundwater).

In general, exposure may occur when contaminants migrate from the Site to an

exposure point (i.e., a location where receptors can come into contact with

contaminants) or when a receptor comes into direct contact with waste ori

contaminated media at the Site. An exposure pathway is complete (i.e., exposure

occurs) if there is a way for the receptor to take in contaminants through ingestion,

inhalation, or dermal absorption of contaminated media or waste.

7.1.3.3 Contaminant SourcesAs a result of waste disposal practices at the Site, sources of potential contaminantrelease were considered to exist as:

• Buried wastes;

• Waste constituents that have sorbed to soil in the saturated and unsaturatedzone; and

• Waste constituents occupying soil pore space in the saturated' andunsaturated zone.

These sources are characteristic of the nine areas determined to be contaminated

(Page 7-3).

7.1.3.4 Contaminant Migration

The distribution of chemicals associated with on-Site waste disposal indicate migration

through environmental media is occurring. In general, the migration of Site

contaminants will be controlled by physical conditions at the Site and the inherentphysical and chemical properties of the migrating compounds.

Because the mechanism of release and transport of a chemical are important elementsin an exposure pathway, the physical and chemical properties of each chemical were

used to approximate its general behavior in the environment. The physical andchemical properties of the chemicals of potential concern have been obtained from theliterature as appropriate, and approximated, if necessary for use in risk assessment. A

list of these properties for the chemicals of potential concern is provided in Table 7-14.

Potential mechanisms for contaminant release at the Site include:

i• Leaching of contaminants into the groundwater and downgradient migration;

• Volatilization of subsurface and surface contaminants from the Site to theambient air;

• Generation of fugitive dusts from exppsed soil areas;

• Groundwater discharge to nearby wetlands; and

• Surface runoff of contaminants from the Site.

Remedial Investigation Report i>hc liUA / i j>ACS NPL Site, Griffith, Indiana Pace 12Revision. DRAFT 20-SEPTEMBER-91

As a result of wastes disposed, it is evident that surface water and sediments, surface

and subsurface soils, upper and lower groundwater aquifers, and the ambient air are

media impacted by contamination at and near the Site. Sections 5 and 6 of the RI

Report contain information regarding contaminant distribution and the fate and

migration of chemicals at the Site. Each of these mechanisms for contaminant releaseat the Site are discussed in Section 6.

7.1.3.5 Selection of Exposure Pathways For Risk Assessment

The potential exposure pathways at the Site were based on the potential contaminant

migration pathways and the Site setting. These potential exposure pathways were

evaluated to determine whether they are complete or have the potential to be

complete in the future. Current use of the Site and adjacent land and potential future

land uses were considered in the analysis.

7.1.3.5.1 Current Land UseCurrent land use of the Site and surrounding area was based primarily on information

gathered during Site visits. Other sources of information that assisted in this

evaluation included zoning maps, census information, and aerial photographs. After

defining the current land use at the Site, a determination of human activities and

behavioral patterns was made. This approach was based on "common sense" and not

on any specific data sources, but rather on a general understanding of the types ofactivities that may be associated with the land use.

Several potential exposure pathways were assumed to exist under the current land use

scenario. These exposure pathways are summarized below and in Table 7-15.\

Off-Site Residents

Incidental ingestion of contaminated water from the upper aquifer (childrenswimming in a pool or playing in lawn sprinklers).

Dermal absorption of contaminated water from the upper aquifer (childrenswimming in a pool or playing in lawn sprinklers).

Ingestion of contaminated water from the lower aquifer.

Dermal absorption of contaminated water from the lower aquifer whilebathing.

Remedial Investigation Report ShLi lUN /.l.jACS NPL Site, Griffith, Indiana Page 13Revision: DRAFT 20-SEPTEMBER-91

• Inhalation of VOCs released from water from the lower aquifer during itshousehold use (e.g., bathing, showering).

• Inhalation of VOC emissions released from subsurface soil contamination.

• Inhalation of contaminants entrained by fugitive dusts emanating fromsurface contamination at Kapica-Pazmey.

Adolescents Playing On-Site (Trespassing)

• Inhalation of volatiles released from subsurface soils at the Site.

• Inhalation of fugitive dusts released from surface soil contamination atKapica-Pazmey.

• Incidental ingestion of contaminated surface soils at Kapica-Pazmey.

• Dermal contact with contaminated surface soils at Kapica-Pazmey.

• Incidental ingestion of contaminated surface water from wetlands anddrainage ditches.

• Dermal contact with contaminated surface water from wetlands and drainageditches.

• Incidental ingestion of contaminated sediments from wetlands and drainageditches.

• Dermal contact with contaminated sediments from wetlands and drainageditches.

On-Site Workers at the Site

• Inhalation of volatiles released from subsurface soil contamination at theSite.

• Inhalation of fugitive dusts migrating from Kapica-Pazmey.

In addition to the exposures that exist for each population as described above, it is

possible that a trespasser may also be an off-Site resident, and on-Site workers may be

an off-Site resident. Thus, while pathways have been combined for each individual

population, populations could also be combined, as appropriate (e.g., off-Site resident

and trespasser) to evaluate the maximum exposure of a population that is reasonably

expected to occur at the Site. The following sections discuss the potential for exposure

to receptors through specific environmental media, and areas, as appropriate, for

current land use conditions.

" Revision: DRAFT 20-SEFTEMBER-91

— 7.1.3.5.1.1 Off-Site Residents (Including Trespassers)

Residential dwellings exist near the boundaries of the Site. The current land use takes

into account that there are residents who have access now and will have access in the•»future to contaminated areas of the Site. This access may actually increase in future

years, because of the possibility that current ownership may change, and land access

will be less restrictive. Given that the Baseline• Risk Assessment assumes the "no-

action" alternative (i.e., the risks to human health which may occur at anytime in the

** future if U.S. EPA does not require some remediation of the Site), it is plausible that

off-Site residents, including trespassers, may be exposed to contaminants at the Site.

#

7.1.3.5.1.1.1 Potential Exposure Through Groundwater Use

* Two groundwater aquifers have been identified at the Site during the RI: an upper

- aquifer and a lower aquifer. A continuous clay layer was documented across the Site

* effectively separating the two systems (see previous sections on geology andhydrogeology of the Site for details). The lower aquifer is used for drinking water

^ purposes; however, the upper aquifer is not classified for drinking water use. In fact, a

survey of homes adjacent to the Site performed during the RI indicated that private

wells exist in both aquifers; however, the upper aquifer is reportedly only used for non-

potable purposes (e.g., lawn care, car washing). However, some persons located one-

half mile north (upgradient) of the Site reportedly had used the upper aquifer for

drinking water purposes as recently as five years ago. No private wells screened in the

w upper aquifer were sampled during the RI; lower aquifer private wells were sampled""' (see Figure 4-13 for locations of private wells).

* Local officials (City of Griffith - Office of Public Works) indicated that there is no

ordinance in place which would restrict the placement of wells for new construction.

* Most City residents use the City water supply system for drinking water; someresidents do use private wells screened in the lower aquifer. There are no municipal

*» wells used locally by the City of Griffith. However, a pump station used to supply

water to City residents is located at 45th Street and Glenwood in Griffith. The source

— of this water is the Gary-Hobart Company. The pump station supplies three overheadstorage tanks for distribution.

Remedial Investigation ReportACS NPL Site, Griffith, Indiana Page 15Revision: DRAFT 20-SEPTEMBER-91

7.1.3!5.1.1.1.1 Upper AquiferThe groundwater flow pattern in the upper aquifer has been shown to be confined to

within a few hundred feet of the Site boundary. Some homes at greater distances from

the Site were found to maintain wells in the upper aquifer and reportedly use thewater for lawn care and other non-potable uses. If contaminated groundwater were to

migrate to these off-Site wells, exposure might be possible while gardening or if

children were to play in the water.

Groundwater flow in the upper aquifer is controlled by several factors as discussed in

previous sections of this RI Report. The flow of groundwater in the upper aquifer

appears to be diverted towards an excavation near the active landfill used to de-water

the landfill, and by the wetlands which surround the Site. The fire pond acts as an

injection point creating a groundwater high at the Site which influences flow.

Since the groundwater flow paths are controlled primarily by water injection at the

firepond and dewatering at the landfill, changes in either of these activities could result

in changed flow paths and therefore, the potential might exist for contaminants in the

upper aquifer to migrate to off-Site locations, presenting an exposure potential to

residents who use private wells screened in the upper aquifer near the Site.Groundwater modeling was not performed to predict the fate and transport of

contaminants in groundwater; therefore, it was assumed that on-Site groundwater

chemical concentrations may be equivalent to off-Site concentrations, in time, if not

mitigated.

If no action were taken at the Site to mitigate contaminant release to groundwater,and the plume were to reach private wells in the upper aquifer, residents could beexposed to contaminants in the water. For purposes of this risk assessment, a child,

age 5-15 years old, using the water for play (using water in a swimming pool), was

selected to represent a "worst case" population among off-Site users of the upper

aquifer (this is consistent with the intent of the current guidance in defining themaximum exposure that is reasonably expected to occur). Children could be exposedto contaminants in water from the upper aquifer through the following exposure

pathways:

• Incidental ingestion of water while swimming in a pool containingcontaminated groundwater from the upper aquifer; and

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana Page 16Revision: DRAFT 20-SEPTEMBER-91

• Dermal exposure while swimming.

The Griffith Municipal Landfill was also evaluated separately for its potential impact

on groundwater. There is evidence that the landfill is generating leachate. The

leachate is being controlled by a collection system (de-watering excavation).

Monitoring wells located in the upper aquifer, and down-gradient of the landfill appear

to indicate the collection system has been effective in limiting release of contaminants

,(in leachate) to the upper aquifer.

Based on the RI, there is no evidence that release of contaminants associated with the

landfill, is occurring, or has occurred in the past. Contaminant release from the

landfill, based on cessation of the collection system, has been modeled to evaluate

potential future land use exposures (see Section 7.1.3.5.2.1.1).

7.1.3.5.1.1.1.2 Lower Aquifer

Eight private wells located in the deep aquifer were analyzed during the RI and had

no detectable levels of contamination (two additional wells were sampled in January

1991). Both the Site and landfill facilities maintain wells in the lower aquifer; the well

at the landfill facility is used for drinking water; the wells at the Site are used for

industrial processes and for drinking water.

There appears to be a substantial amount of retardation of contaminants migrating

vertically from the upper aquifer to the lower aquifer due to the confining clay layer.While the confining clay layer was found to be only 2.5 ft thick in one limited area,

generally it is .greater than 6 ft thick across the Site. The clay layer provides an

effective separation between the two aquifers because of its high organic carbon

content and low permeability. The potential for contaminant exposure via the lower

aquifer is considered to be low. Contamination was found in the lower aquifer at

monitoring well MW9D, but was not found at any other lower aquifer monitoring

wells, indicating that the contamination is limited and has not extended off-Site. For

the purposes of risk assessment, contaminants detected in the lower aquifer were

assumed to migrate at their present concentrations to off-Site lo'cations where exposure

might occur. Exposure pathways include:

Remedial Investigation Report i>bc i iO.N T.l.jACS NPL Site, Griffith, Indiana Paee 17

• Revision: DRAFT 20-SEPTEMBER-91

• Ingestion of water;

• Dermal absorption of contaminants from water during bathing; and

"" • Inhalation of the VOCs released from water during its household use (e.g.,showering, bathing, etc.).

*" 7.1.3.5.1.1.2 Potential Exposure to VOCs in Ambient Air

Contaminants can be released' to the air through volatilization. Numerous VOCs have** been detected in various Site media from which volatilization could occur. The

majority of volatiles are located at discrete areas of the Site. These areas include them on-Site containment area, off-Site containment area, Kapica-Pazmey, and the still

bottoms and treatment lagoon area. Each of these areas, with the exception of

•» Nt"*' Kapica-Pazmey, have been covered with clean material. Although VOCs are alsodetected in other media (e.g., groundwater), it is expected that the greatest quantity of

^ release of VOCs to air would come from the subsurface soils from the areas just

described.

Several factors may reduce the significance of VOC releases to ambient air. It is

believed that most of the VOCs are present at the water table. The soil moisture in••this zone may serve to inhibit the release of VOCs. Once released, the VOCs wouldbe diluted with ambient air.

The quantity of VOCs emanating from the contaminated subsurface soils is expected

*" to be low compared to that from the Site. No air samples were taken in the fieldduring the RI because of the difficulty in distinguishing air pollutant sources at the Site

m from anthropogenic background. However, it should be recognized that volatiles

released from Site pollution may pose potential inhalation exposure (proportionately)

«• to on-Site as well as'off-Site populations residing near the Site and to children who

may play (trespass) on-Site. Predicting the amount of exposure quantitatively for this

— risk assessment required estimating potential emissions from the subsurface soils andusing a dispersion model to obtain on-Site and downwind VOC concentrations.


7.1.3.5.1.1.3 Potential Exposure to Contaminants Via Fugitive Dust

The potential for contaminants to be released to air via fugitive dust is expected to

occur only at the Kapica-Pazmey area. In this area, there are unvegetated areas of

surface soil contamination where fugitive dust generation from wind erosion is possible.

The bare soil is visibly contaminated at this location and based on particle size analysis,

soil particles are conducive to such a release. Dust generation was observed in this

area during the RI.

There is little or no potential for fugitive dust release from other areas where

contamination exists. The on-Site containment area, off-Site containment area, and

still bottoms and treatment lagoon area are covered with clean material, effectively

eliminating the potential generation of contaminated fugitive dust. The still bottoms

and treatment lagoon area is covered by construction and the off-Site containment

area is covered by dense vegetation.

The greatest potential for inhalation of contaminated dusts would be by children

playing (trespassing) at the Kapica-Pazmey area. However, contaminants entrained on

soil particles in air could also migrate to off-Site residences near the Site where they

might be inhaled by receptors (residents).

7.1.3.5.1.1.4 Potential Exposure Via Direct Contact with Contaminated Soils

Surface soil contamination is evident at Kapica-Pazmey where potential exposure via

direct contact is considered to be plausible for adolescents trespassing on-Site.Subsurface contamination beneath clean cover material exists at other locations on-Site

but does not represent a direct contact exposure potential under current conditions.

The source area at Kapica-Pazmey is an open area adjacent to Site buildings. The

open area is visually contaminated (see Table 7-7 for analytical results) and is

unvegetated. Access to the property is partially restricted by fences and buildings but,

the area is not completely restricted.

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana Page 19Revision: DRAFT ' 20-SEPTEMBER-91

The potential for exposure to contaminated soils under current conditions is plausible

only for soils located at the surface. Contact with soils below ground surface would

require excavation (digging) and is not likely to occur on a regular basis. Risks to

subsurface soils were considered under the future land use scenario.

The most plausible population which may contact surface soils in these areas is

considered to be adolescents who may play (trespass) on the Site. To assess potential

health risks associated with contaminated surface soils, contaminant exposure was

quantified by assuming adolescents regularly play at the Kapica-Pazmey location.

Exposure routes considered included incidental ingestion and dermal absorption.

7.1.3.5.1.1.5 Potential Exposure Via Contact with Surface Water and Sediments

Wetlands are found on all sides of the Site. In addition there are drainage ditches

near the Site which transport overland runoff in the area. Surface water and sediment

samples (see Tables 7-9 and 7-10 for a summary of analytical results) collected and

analyzed from these Site features indicate the presence of contamination.

Portions of the groundwater table discharge from the upper aquifer into the wetlands

and surface water surrounding the Site. It is possible that if no action is taken,

groundwater with increasing contaminant levels would discharge to the wetlands. If

this were to occur, people and wildlife might be exposed to contamination in these

media currently and in the future.

To assess the health risks associated with contamination detected in surface water and

sediments, adolescents were assumed to play (trespass) on-Site and become exposed to

these media on a regular basis. Exposure was assumed to be plausible through

incidental ingestion and dermal contact.

It is unknown whether hunting activities take place on-Site. However, it is expected

that if hunting does occur, this is a small potential user group. The Site is surrounded^-

by residences, commercial businesses, and industry making hunting an impractical

matter.

Remedial Investigation Report ShL 1 iO.N /.l.jACS NPL Site, Griffith, Indiana Page 20

" Revision: DRAFT 20-SEPTEMBER-91

The surface waters on-Site are not indicative of habitats for major sport fishing

populations. Thus, fishing appears to be inherently limited by the physical makeup of

the Site.«v

It is reasonable to conclude that terrestrial and aquatic organisms taken from the Site| M

would not constitute a major source of food for human consumption. Potential

exposure to chemical contaminants via ingestion of aquatic species or wildlife was not

** evaluated due to the lack of a defined user group and the reasonable assumption of

limited potential for exposure.

7.1.3.5.1.2 On-Site Workers at the Site

<• <w' ACS continues to maintain its operations and thus, employees of the Site represent a

population potentially exposed to Site contamination under current conditions. The

M Site has effective access limitations and only authorized personnel are allowed on the

property.\

There are no apparent direct contact exposures to surface water or soils at the Site.

This area of the Site has been covered by clean fill material, effectively eliminating the

potential for direct contact with buried materials, particularly in the area of on-Site

containment.

There is only one surface water body location on the Site. This location was analyzed

** and found to contain relatively low levels of contaminants. This lagoon is actively usedfor Site processes, and workers may encounter the lagoon. However, working activities

* near the lagoon were considered to be voluntary, and associated with job requirements.

Site workers were assumed to be trained in their job functions, and have an

* understanding of potential worker hazards. The Occupational Safety and Health Act

(OSHA) requires compliance with safety and hygiene standards to reduce potential

M risks to these employees. Site worker exposure to the lagoon was not evaluated in the

Baseline Risk Assessment.

The Site maintains four groundwater wells. These wells are used for industrial

purposes, as well as for drinking water. All four of these wells are installed in bedrock

at a depth greater than 300 ft. The RI has focused on evaluating the upper aquifer

and the lower sand and gravel aquifer, separate from the bedrock. The bedrock

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana Pace 21Revision: DRAFT • 20-SEPTEMBER-91

aquifer has not been identified as a concern in the RI, nor has it been defined as being

Site-related. Analysis of one of the four wells indicated no contamination. The

bedrock aquifer was not considered further in the risk assessment.

7.1.3.5.1.2.1 Potential Exposure to Contaminants Via Inhalation of VOCs

The most apparent exposure to workers at the Site would be via inhalation of

gases/vapors released from their operations; this is apparent based on observation

during Site visits. The VOC releases emanating from buried materials on the Site (on-

Site containment area, and still bottoms and treatment lagoon area) are in addition to

that of the Site operations. To assess health risks to Site workers due to VOC releases

to ambient air, only those releases associated with the buried contamination on and

near the Site were considered.

7.1.3.5.1.2.2 Potential Exposure to Contaminants Via Fugitive Dusts

As described previously, the Kapica-Pazmey area has exposed contamination at the

surface. Site workers may be exposed via inhalation to downwind concentrations of

contaminated dusts emanating from the Kapica-Pazmey area.

7.1.3.5.2 Future Land Use

There are no hard-and-fast rules by which to determine alternate future land use. To

the extent the information was available and applicable, City and County projections of

future land use, census projections, and information regarding land use trends were

used to assist in the determination of future land use for this risk assessment. Whilethese sources may provide useful information, they cannot always be interpreted as

providing proof that a certain land use will or will not occur. Thus, much of the

interpretation for determination of the future use scenario for this risk assessment was

based on professional judgment.

The Zoning District Map (Figure 7-2) for the Town of Griffith indicates the Site is

zoned general industrial. However, there is residential zoning adjacent to the Site and

some residences exist within the industrial zoned areas. Although future trends

regarding development of the area are not known with certainty, it may be possible

that the Site or areas near the Site could be developed for residential use (i.e., the

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana . Page 22Revision: DRAFT 20-SEPTEMBER-91

probability that the Site will support residential land use in the future is not so

exceedingly small to preclude using this scenario for this assessment). The residential

use scenario was selected based on concurrence with the U.S. EPA Region V RPM.

and Technical Support Group.

The likelihood of residential development at and near the Site in the future is

supported primarily by the presence of residences currently near the Site. In addition,

because the Baseline Risk Assessment must evaluate the Site on the basis that no

action is taken to mitigate the Site and no restrictions and/or institutional controls are

placed on future use of the Site, the residential pathway seemed plausible for risk

assessment. An alternate future use is for industrial purposes. The potential exposure

pathways associated with future land use of the Site for industrial purposes has been

included in this risk assessment under the current land use scenario. An evaluation of

exposure pathways based on potential future land use changes is summarized in Table

7-15 and discussed below.

Hypothetical Resident Living On-Site

• Ingestion of contaminated groundwater from the lower or upper aquifer.

• Dermal absorption of contaminated groundwater from the lower or upperaquifer.

• Inhalation of VOCs released from water from the lower or upper aquiferduring its household use (e.g., showering, bathing).

• Dermal absorption and incidental ingestion of contaminants adsorbed ontosediments and soils.

Dermal absorption and incidental ingestion of contaminants detected insurface water.

• Inhalation of volatiles released to ambient air.

7.1.3.5.2.1 Hypothetical Resident Living On-Site

7.1.3.5.2.1.1 Potential Exposures Via Groundwater

As has been previously stated, there are two groundwater aquifers at the Site; upper

and lower. For the purpose of this risk assessment, it was assumed that a residential

well could be screened in either of the aquifers and used as a drinking water source.


Without remedial action for Site clean-up, nor institutional restrictions or other

limitations, as specified by guidance for the Baseline Risk Assessment, risks have been

quantified for residential use of either aquifer for drinking water purposes. The routes

of contaminant intake evaluated include ingestion and dermal absorption of

groundwater, and inhalation of VOCs released from groundwater during its household

use.

Contaminant concentrations were assumed to remain at their present levels when

performing the calculations to estimate the amount of exposure under future land use

conditions. This assumption may over- or under-estimate the exposure. Using steady-

state conditions does not account for substantial future releases of-unmitigated source

materials to groundwater that may occur over time, nor does it account for source

depletion and attenuation of materials through environmental fate and transport

processes. It is not known with certainty the resultant (future) groundwater

concentrations due to these potential (collective) impacts.

In addition to the Site-specific geologic and hydrogeologic conditions, and extraneous

grouridwater influences (as previously discussed in the RI Report), many chemical and

physical properties affect chemical transport and fate in groundwater. Some of the

more important mechanisms include leaching from the surface, advection (infiltration,

flow through the unsaturated zone and flow with groundwater), dispersion, sorption

(adsorption, desorption, and ion exchange), biological degradation, hydrolysis,

oxidation, reduction, complexation, dissolution, and precipitation. In accordance withcurrent U.S. EPA guidance documents, current concentrations can be used to

represent future concentrations assuming a steady-state condition when groundwater

modeling is not used.

For directly assessing the potential impact of the Griffith Municipal Landfill on

groundwater, the collection/de-watering system was assumed to be stopped, and a

model was used to determine the potential release of contaminants in leachate to

groundwater. This evaluation was made to assess the potential risks to a hypotheticalx future use residence, with a private well, located immediately adjacent to, and

downgradient from the landfill.


7.1.3.5.2.1.2 Potential Exposure Via Contact with Contaminated Soils

Little contamination exists at ground surface at the Site. In general, the contaminantshave been buried below ground. Therefore, exposure to soils is limited unless the

subsurface soils are excavated and brought to the surface where exposure may be

possible. Exposures were quantified for subsurface soils being unearthed and brought

to the surface consistent with the "no-action" alternative, and future land use for

residential development. The contaminated subsurface soils were assumed to beexcavated during hypothetical development of residences on-Site, and used as fill

material and cover material in yards, gardens, and playgrounds. This exposure pathway

is highly subjective; however, using such a pathway may be more important as it relates

to the feasibility study in determining which chemicals in subsurface materials may

require evaluation in the detailed analysis of alternatives.

The analytical results for subsurface and surface soils have been averaged together toaccount for mixing of soils, where, appropriate, to arrive at exposure point

concentrations. It should be recognized that there are degradative processes which

would act to reduce contamination over time. However, these processes are complex

and their impact has not been predicted for risk assessment; exposure point

concentrations assume steady-state conditions.

7.1.3.5.2.1.3 Potential Exposure Via Contact With Contaminated Surface Water and

Sediments

For future land use considerations, the wetlands and drainageways were assumed to beprotected, and»remain unchanged from current conditions. Contaminants were also

assumed to reflect steady-state conditions. This assumption appeared reasonable sincethe sources, under the no action alternative, may continue to contribute to surfacewater and sediment contamination. Therefore, contact with surface water and

sediments would be the same as described for the current land use scenario. On-Site

residents were assumed to have occasional contact with contaminated surface water

and sediments through the dermal absorption route and incidental ingestion.

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana Page 25

"* Revision: DRAFT 20-SEPTEMBER-91

„. 7.1.3.5.2.1.4 Potential Exposure Via Inhalation of Contaminants Released to Air

Fugitive dust generation and VOCs emanating from contaminated areas are the two

m potential release routes to air.

Under future land use considerations, it was assumed that fugitive dust generation

would be effectively minimized by conditions evident in an urban setting. That is,

unearthed contaminated soils brought to the surface, would be covered by vegetation,

building construction, roadways, and other ground cover features. These features, in

essence, reduce the potential for wind and/or mechanical erosion forces necessary to

** generate dusts. VOC release could potentially occur through the soil cover into the

ambient air. This pathway is similar to the current land use pathway where VOCs in

** 'w' subsurface soil are released from the source through the ground cover to the ambient

air. The mechanism for VOC release would still exist and may be enhanced under

— these circumstances presenting potential exposure to on-Site residents via inhalation of

VOCs.

7.1.3.6 Quantification of Human Exposure Estimates

^ Exposure is defined as the contact of an organism with a chemical or physical agent.

In this assessment, exposure (intake or dose) is normalized for time and body weight

and is expressed as mg chemical/kg body weight-day (mg/kg-d). Five factors are used

to estimate intake; exposure frequency, exposure duration, contact rate, exposure point

^ concentrations, and body weight. This section summarizes the exposure factors used in

this assessment. The methodology (equations) for calculating estimates of humanexposure is provided in Appendix T.

«

An additional term in the dose estimate equation is "averaging time," which

* normalizes the dose over a specified period of time. For chemicals which are potential

carcinogens, dose estimates are normalized over a 70 year lifetime to allow comparison

m with toxicology information which is generated from studies in which the test species is

exposed to the chemical over the majority of its lifetime. Dose estimates which are

„ used to assess the non-cancer effects of chemicals are normalized over the period ofexposure.


Recently published national statistics on the number of years spent by an individual in

one residence indicate that the average number of years spent at a single residence is 9

and the 90th percentile figure is 30 years (U.S. EPA, 1989). This assessment uses the

90th percentile figure to represent the period of exposure for many of the exposures

assumed to occur at and near the Site. Thus, the averaging time for carcinogens versus

noncarcinogens is 70 years and 30 years, respectively. There are instances where the

exposure period is less than 30 years (e.g., child swimming - 10 years, adolescent

playing on-Site -10 years). In these cases, the averaging time for carcinogens is still 70

years; however, non-cancer effects of chemicals are normalized over 10 years.

Levels of exposure are quantified to allow comparison with exposure levels

corresponding to adverse health effects. Estimates of contaminant exposure can be

derived using the following general equation:

Contaminant >Dose = Chemical x Contact x Exposure Frequency x 1 x 1

Estimate Concentration Rate and Duration Body Weight AveragingTime

The contaminant dose estimate may represent either an "administered" or

"absorbed" dose. An administered dose refers to a contaminant exposure which

occurs at an exchange boundary of an organism. For example, exposure via ingestion

(drinking groundwater) is based on delivery of the contaminant to the gastrointestinal

tract. Equations which estimate doses for some exposures incorporate a variable whichaccounts for absorption of the contaminant across the exchange boundary into the

blood stream. This estimate is referred to as an "absorbed dose estimate." The

distinction between administered and absorbed dose estimates is necessary for proper

comparison with toxicity information, as is further described in the Toxicity

Assessment. \

The most recent EPA guidance states that actions at Superfund sites should be based'

on an estimate of the "reasonable maximum exposure" expected to occur under both

current and future land use conditions. The reasonable maximum exposure is defined

as the "highest exposure that is reasonably expected to occur at a site" (U.S. EPA,

1989). The intent of the reasonable maximum exposure is to estimate a conservative


exposure case (i.e., well above the average case) that is still within the range of

possibilities. Each exposure factor has a range of possible values. In accordance with

the guidance, this assessment has used values for the exposure factors that result in an

estimate of the reasonable maximum exposure.

7.1.3.6.1 Groundwater/Surface Water Exposures

Exposure to contaminants through the use of groundwater as a water supply source

from either the lower or upper aquifer was estimated for the ingestion, dermal

absorption, and inhalation routes of exposure. The exposure assumptions used to

describe groundwater use are summarized for individual populations in Appendix T.

Intake equations are also presented in this Appendix.

The principles used to calculate groundwater dose estimates were used to evaluate

exposure to surface water; however, the parameters used to calculate surface water

exposure are different. Assumptions applied to the surface water exposure pathways

are contained in Appendix T for each population.

Some of the more important intake assumptions are highlighted below for each

exposure route.

7.1.3.6.1.1 Ingestion

This assessment follows the U.S. EPA's standard set of exposure assumptions to

describe exposure through ingestion of drinking water (U.S. EPA, 1989). Theseassumptions include an ingestion rate of 2 liters per day for drinking water.

An ingestion rate of 0.05 L/hr was used for incidental ingestion of water while

swimming (2.6 hours/day, 52 days/year), and 0.005 L/hr for incidental ingestion of

surface water for children assumed to play near wetlands and drainage ways (3hours/day, 52 days/year).

7.1.3.6.1.2 Dermal Absorption

Exposure through dermal absorption is a function of more variables than ingestion,

and there is no standard set of exposure assumptions. The assumptions used in this

assessment are based on recent EPA guidance and professional judgment.


exposure case (i.e., well above the average case) that is still within the range of

possibilities. Each exposure factor has a range of possible values. In accordance with

the guidance, this assessment has used values for the exposure factors that result in an

estimate of the reasonable maximum exposure.

7.1.3.6.1 Groundwater/Surface Water Exposures

Exposure to contaminants through the use of groundwater as a water supply source

from either the lower or upper aquifer was estimated for the ingestion, dermal

absorption, and inhalation routes of exposure: The exposure assumptions used to

describe groundwater use are summarized for individual populations in Appendix T.

Intake equations are also presented in this Appendix.

The principles used to calculate groundwater dose estimates were used to evaluate

exposure to surface water; however, the parameters used to calculate surface water

exposure are different. Assumptions applied to the surface water exposure pathways

are contained in Appendix T for each population.

Some of the more important intake assumptions are highlighted below for each

exposure route.

7.1.3.6.1.1 Ingestion

This assessment follows the U.S. EPA's standard set of exposure assumptions to

describe exposure through ingestion of drinking water (U.S. EPA, 1989). These

assumptions include an ingestion rate of 2 liters per day for drinking water.

An ingestion rate of 0.05 L/hr was used for incidental ingestion of water while

swimming (2.6 hours/day, 52 days/year), and 0.005 L/hr for incidental ingestion of

surface water for children assumed to play near wetlands and drainage ways (3hours/day, 52 days/year).


Exposure through dermal absorption is a function of more variables than ingestion,

and there is no standard set of exposure assumptions. The assumptions used in this

assessment are based on recent EPA guidance and professional judgment.


* Revision: DRAFT 20-SEPTEMBER-91

^ Dermal absorption exposure is a function of permeability of the skin, surface area

_ exposed, and length of exposure. Chemical-specific permeability constants (PC) (which

approximate the rate of chemical movement across the skin) are not available for all

contaminants. Where they are not available for VOCs, this assessment assumes that

contaminants penetrate the skin at the same rate as toluene (U.S. EPA directive) when

toluene is present. When toluene is not present, the chemical of concern with the next

greatest permeability potential was used. The PC for water was used as a default value— for metals, and the PC for 2-butanone was used as a default value for semi-volatiles

(U.S. EPA directive). The assessment assumes that dermal absorption of water occurs

** through the use of groundwater while showering, when children swim in pools filled

with contaminated groundwater, and when children play on-Site and become exposed

«• '"***' to surface water.

«, 7.1.3.6.1.3 InhalationInhalation of VOCs released from drinking water to household air was approximatedusing a draft methodology supplied by the U.S. EPA Exposure Assessment Group,Office of Health and Environmental Assessment ("Screening Method for EstimatingInhalation Exposure to Volatile Chemicals from Domestic Water"). The procedurehas evolved from research performed by Julian Andelman, University of Pittsburgh.Appendix T contains the formula for deriving concentrations of chemicals released toair while showering. Appendix Z contains the methods used to arrive at a chemicalconcentration in air as a result of volatilization. The concentration estimate was then

•W** applied to standard methods for calculating daily intake.

m- Inhalation of volatiles released from contaminated water in a swimming pool or fromsurface water was considered negligible and not quantified in this risk assessment.

«7.1.3.6.2 Soil/Sediment Contact Exposures

ai_ Exposure to contaminants in soils and sediments were assumed to occur through

dermal absorption and incidental ingestion. Soil and sediment contact impacts

^ populations considered in both current and future land use scenarios (i.e., trespassers,

hypothetical on-Site residents). The exposure variables have been adjusted accordingly

based on the population exposed. For specific information regarding the exposure


variables associated with each population and route of exposure, refer to Appendix T.

These tables also contain the equations used to calculate intake. Some of the more

important exposure assumptions used to calculate intake are provided below.

7.1.3.6.2.1 Incidental Ingestion

Standard assumptions were used to calculate incidental ingestion of soil/sediment.

Contact is assumed to occur 6 months per year because snow cover and/or frozen

ground is assumed to prevail 6 months per year. A standard ingestion rate of 100 mg

soil/day was used.


As with dermal absorption of water, there is no standard set of exposure assumptions

for dermal absorption from soil or sediment. Dermal absorption of soil/sediment is a

function of permeability of the skin, surface area exposed, soil/sediment deposition,

and length of exposure. Estimates of the rate of absorption of chemicals from

soil/sediment are not available for many contaminants so the method stipulated in U.S.

EPA guidance was used. Exposure through dermal absorption from soil/sediment was

calculated using specific dermal absorption factors when available, otherwise an

absorption factor of 30% was used for organic compounds. The organic value was

based on information obtained from ECAO for PAHs. Metals do not readily absorb,

thus 1% was assumed to be a reasonable estimate of absorption for these elements.

7.1.3.6.3 Air Exposures7.1.3.6.3.1 Inhalation

Subsurface contamination at several areas of the Site contain high concentrations of

VOCs, potentially providing a continuous source of releases to the air. Climatic

conditions were assumed to limit volatilization to 6 months of the year (absent or

negligible during the winter). In addition, fugitive dust generation is anticipated at the

Kapica-Pazmey area. Both of these mechanisms of contaminant release to the ambient

air may pose an inhalation hazard and have been included for risk assessment. On-Site

and off-Site exposures have been evaluated for current and future land use

populations, as appropriate.

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana > Pace 30Revision: DRAFT 20-SEPTEMBER-91

Standard assumptions have been applied to the inhalation pathway when available,

while professional judgment was utilized for some of the parameters. Exposure

assumptions and the equations to calculate intakes for the air pathway for each

population are listed in Appendix T.

7.1.3.7 Exposure Point Concentrations

U.S. EPA guidance requires that the concentration of contaminants in a given medium

(groundwater, soil, etc.) used to represent the exposure point concentration be derived

by calculating the 95% upper confidence limit on the mean (data assumed to be either

normally or log-normally distributed) of sample concentrations (95% UCL) (exceptions

for groundwater exist - see discussion below in Section 7.1.3.7.1). If the 95% UCL

value exceeds the maximum value identified, the maximum value is to be used instead.

In the present assessment, a log-normal distribution was assumed, and confirmed

through analysis of covariance (Appendix U contains details for determination of

exposure point concentrations). Ninety-five percent UCL values (based on a log-

normal distribution) were calculated for all contaminants identified in Site media. In

most instances, the 95% UCL values were greater than the maximum concentrations

identified for these chemicals because of the large degree of variability within the

contaminant concentration data. Therefore, maximum contaminant concentrations

were used to represent most exposure concentrations for these data. UCL values were

used only when less than the maximum concentration. Calculations of UCLs and

comparisons to maximum concentrations is presented in Appendix U. Exposure point

concentrations (either UCL or maximum concentrations) selected for each area arecontained in Table 7-16.

7.1.3.7.1 Groundwater

For groundwater, there are no data available to directly describe concentrations at

exposure points (private wells located off-Site). However, contamination has been

detected at monitoring wells located at the periphery of the Site. Contaminants could

potentially migrate off-Site in the upper aquifer and, because receptors surround the

Site, there is the potential for contamination of private wells screened in the upper

aquifer. Because the potential exists for migration off-Site under current land use, the

U.S. EPA Region V requires evaluation of off-Site exposure to groundwater.


Monitoring well analytical data were used directly to estimate potential exposures from

either the upper or lower aquifers using either the UCL or maximum contaminant

concentration, as appropriate. Under current land use conditions, the exposures that

may occur are off-Site. Therefore, using the UCL or maximum (lower of the two)

concentration was considered to be reasonable to quantitate exposure (based on a

teleconference with U.S. EPA). However, for future land use, a hypothetical well is

assumed to be placed on-Site, and the maximum concentration was used. This is in

accordance with recent U.S. EPA guidance (March 1991). In addition, to calculate

future land use exposures, concentrations of contaminants in both aquifers were

assumed to remain steady-state.

7.1.3.7.1.1 Griffith Municipal Landfill Groundwater Modeling Results

It has been shown that de-watering at the Griffith Municipal Landfill has so far limited

the migration of contaminants away from the Site boundaries. However, it cannot be

assumed that the landfill de-watering system will be operated indefinitely. Therefore,

the U.S.G.S. Modflow model was used to evaluate the potential changes which would

occur in the upper aquifer groundwater flow regime if the landfill de-watering were

discontinued.

Appendix Y contains the numerical modeling results which show that in the current

groundwater flow regime, the groundwater flowing beneath the landfill discharges to

the de-watering excavations. In a future scenario in which the de-watering is

discontinued, the creek would resume its function and groundwater would continue todischarge toward the creek west of the landfill.

The solute transport modeling which was conducted (Appendix Y) shows that the

benzene level (and other landfill constituents) will migrate slowly towards the west.

The upper aquifer surrounding the landfill will not be affected by leaking leachate.

Upper aquifer contamination from the landfill will be limited to the aquifer area

beneath the landfilled area.

A second model, a hand-calculated mass balance method was used to evaluate the

potential impacts from the landfill to the upper and lower aquifer. The model used

Darcy's equation to evaluate the groundwater flow rates (and discharge volumes)

Remedial Investigation Report SECTION 7.1.3ACS NPL Site, Griffith, Indiana Pace 32Revision: DRAFT 20-SEPTEMBER-91

within the upper and lower aquifer. The following form of Darcy's equation was used:

Q = -K i A

where:Q = water volumeK = hydraulic conductivityi = hydraulic gradient (ft/ft)A = area water flows through (ft2)

The mass balance calculation to estimate potential contaminant loading can be

made for each groundwater flow component using the following equation:

Qa x Conca = Qb x Conq?

•where:Q = groundwater discharge (flow volume) in a

quantifiable groundwater flow zone.

Cone = contaminant concentration in the quantifiablegroundwater flow zone.

Four groundwater flow components can be defined as potentially affected by the

landfill leachate:

Ql Areal recharge across the landfill area, through the existing cover.

Q2 Horizontal groundwater flow in the upper aquifer beneath the landfill.

Q3 Vertical groundwater flow through the clay confining layer between theupper and lower aquifers.

Q4 Horizontal groundwater flow in the lower aquifer.

Since the concentration and discharge are known in the source area (1), a

concentration can be calculated for the next and subsequent flow areas (2, 3, and

4), on the basis of the known discharges. The calculation is made with above

equation 2, solved for "Conc2"

Conc2 = (Qi x Conci) / Q2


The landfill area of concern (on Figure 4-21) is approximately 1000 feet by 1000

feet, between the 634 contour lines in the northwest and southeast, and the 635

contour line in the northeast. In the current groundwater flow regime.

groundwater flow is toward the landfill de-watering area, shown by the closed 625

foot contour line. Landfill contaminants were not detected in monitoring wells

MW-1 and MW-15, indicating that the groundwater discharge is toward the

northwest. The numerical modeling of the Site with the U.S.G.S. Modflow model

(Appendix Y) showed that groundwater flow in the upper aquifer would still be

toward the west, toward the creek, even if the de-watering activities are ceased at

the Site.

By using known VOC concentrations, calculated flow rates, and mass balance, the

potential VOC concentrations can be estimated. Assuming that the existing cover

is not changed, it was calculated (Appendix Y-2) that approximately 1 million cubic

feet of leachate are generated each year (Qi); this volume represents the

groundwater in the upper aquifer in the area of concern. Several VOCs were

indicated in the leachate sampling results. The contaminant of concern was

benzene. It was detected at concentrations between 2 and 6 ug/L, with an average

concentration of 4.5 ug/L (Appendices Q-l and R-l list leachate results).

Potential Upper Aquifer Effects

In the present condition, the 1 million cubic feet of groundwater is collected each

year by the Griffith Municipal Landfill and is not released to the environment. Ifthe de-watering were to cease, the 1 million gallons of groundwater would

discharge to the creek at the western boundary of the Site (Q2). Under this

condition, groundwater flow is symmetrical toward the creek, so the 1 million cubic

feet of discharge (O_2) to the east side of the creek would represent 50 percent of

the discharge to the creek along the landfill stretch. Another 1 million cubic yards

would be discharging into the creek from the west side. The mass balance

calculation indicates that contaminant loading of the stream in the vicinity of the

landfill would be 2.5 ug/L (benzene). This does take into account the further

dilution which might occur from the creek water flowing into the landfill stretch of

the stream from upstream.



— Potential Lower Aquifer EffectsOn the basis of laboratory results, the mean hydraulic conductivity of the clay

confining layer was 4.8x10-8 cm/sec (Table 4-7)., Field observations indicated thatthe downward hydraulic gradient across the confining layer is approximately 1 ft/ft

(Table 4-6). With these data, it is possible to calculate the groundwater flux (Q3)

"" across the 1000 by 1000 foot landfill area is approximately 50,000 cubic feet per

year, with an average, unattenuated concentration of 4.5 ug/L of benzene.Ml

The groundwater flow across the confining layer (O_3) mixes with the groundwater

*" flowing north in the lower aquifer (Figure 4-22). Although the lower aquifer is

greater than 50 feet thick, it is assumed that the groundwater leaking into the lower<«• "**' aquifer will diffuse across only the upper 20 feet of the aquifer. The annual volume

of groundwater flow represented by the upper 20 feet of the lower aquifer can be

• calculated from the hydraulic conductivity estimated for the lower aquifer (Section

4.5.3.3), the horizontal gradient in the lower aquifer (Section 4.5.3.4), and the cross-

_ sectional- area of the aquifer area of concern (20 x 1000 feet). The calculation

indicates that 290,000 cubic feet (Q4) of groundwater flows to the north beneath

the landfill ,in the upper 20 feet of the lower aquifer. Using the mass balance

equation, it can be estimated that if the benzene were not attenuated duringmigration across the 10 foot clay confining layer, the potential benzene

concentration in the lower aquifer (Conc4) would be less than 1.0 ug/L (0.78 ug/L).

contained in the Superfund Exposure Assessment Manual (U.S. EPA, 1988). Refer to

Appendix V for complete details on the application of these models to arrive at

exposure point estimates for VOCs released to air.

A fugitive dust model was also employed to address the potential for dust release from

surface contamination at Kapica-Pazmey. The methods of Cowherd, et.al. (1985) were

used to arrive at fugitive dust emission rates and exposure point estimates. A

description of this method and its application at the Site is contained in Appendix W.

Again, without the use of sophisticated predictive models, chemical concentrations used

were assumed to remain at steady-state conditions for future land use exposure

calculations.

7.1.4'Toxicity Assessment

This section addresses the nature of the toxic effects which may result from exposure

to the chemicals of concern. The risk assessment addresses two general types of

toxicities which may result from chemical exposure; cancer and non-cancer effects.

Because these two broad types of toxicity are assumed to be expressed through

different biological mechanisms, the methods used to quantify these effects are

different. Although the chemicals have been divided into carcinogens or

noncarcinogens, some chemicals have been evaluated as having the potential to cause

both carcinogenic and noncarcinogenic effects.

7.1.4.1 Dose-Response Relationship

The type, severity, and frequency of occurrence of a given toxic effect observed within

a population (response) is a function of the magnitude of chemical exposure (dose).

Different chemicals which produce similar toxicities within a species usually do so at

different concentrations (i.e., have different toxic potencies). These relative differences

in the dose-response relationships among chemicals are addressed in the risk

assessment by considering "critical toxicity values" developed by the U.S. EPA.

Critical toxicity values have been derived for potential noncarcinogenic effects and

potential carcinogenic effects of the chemicals and are termed reference doses (RFD)

and slope factors (SF), respectively.

Two sources of critical toxicity values were used. The primary source was the U.S.

EPA's Integrated Risk Information System (IRIS) database. A secondary source of

data was the Health Effects Assessment Summary Table (HEAST) published quarterly

by the U.S. EPA! Critical toxicity values were not available for many of the chemicals

of potential concern. To establish those toxicity values, the Environmental Criteria

and Assessment Office (ECAO) and the U.S. EPA Region V Technical Support Group

were contacted to provide additional values and guidance, as appropriate.•

7.1.4.1.1 Noncarcinogenic Effects

Noncarcinogenic effects of chemicals are assumed to display a threshold phenomenon,

i.e., effects are not observed below a given chemical concentration (threshold dose).

Therefore, a health risk is thought to exist only if established threshold doses areexceeded.


Noncarcinogenic health effects include a variety of toxic effects on body systems such

as renal toxicity (toxicity to the kidney), teratogenicity (damage to the developing

fetus), and central nervous system disorders. In many cases, organisms have adaptive

mechanisms that must be overcome before a toxic endpoint (effect) is manifested. The

toxicity of a chemical is assessed through a review of toxic effects noted in short-term

(acute) animal studies, long-term (chronic) animal studies, and epidemiological

investigations.

The noncarcinogenic dose-response relationship is addressed in the toxicity assessment

by considering RFDs, expressed in mg contaminant/kg body weight-day, which are

levels of contaminants not expected to cause adverse health effects in humans,

including sensitive subsets of the population. RFDs are generally estimated from No-

Observed-Adverse-Effect-Levels (NOAEL), determined from animal studies, which are

the highest chemical concentrations which produce no adverse effects. Safety factors

related to various assumptions made (e.g., animal to human extrapolation) are

incorporated in the derivation of the values to result in a more health-protective

estimation.

RFDs for some inorganic compounds are for specific forms (e.g., hexavalent and

trivalent chromium). The chemical analyses performed do not, however, report

concentrations of specific forms, but rather give results in terms of "total" inorganic

chemical. In such situations, it was assumed that unless otherwise known, the most

toxic form is present and its RFD used.

7.1.4.1.2 Carcinogenic Effects

Presently in the risk assessment process, all carcinogens are considered to have a dose-

response relationship with no threshold. Thus, theoretically, any exposure is associated

with some degree of risk.

The cancer potentials of carcinogens are known with varying degrees of certainty,

depending on the amount and quality of scientific information available. The U.S.

EPA has developed a system to review this information and to classify chemicals as to

their likelihood of causing cancer. For example, this classification scheme distinguishes

between chemicals which are known human carcinogens (Group A) and chemicals

which are probable human carcinogens (Group B), based on their cancer causing

Remedial Investigation Report SECTION 7.1.4ACS NPL Site, Griffith, Indiana Pace 38Revision: DRAFT 20-"SEPTEMBER-91

properties in animal studies. The dose-response relationship for an established or

potential carcinogen is incorporated into the SF; a value expressed in (mg/kg-d)-!,

which is directly proportional to the cancer potency of the chemical.

7.1.4.2 Critical Toxicity Values and Toxicity Profiles

The critical toxicity values (RFDs and SFs) used in the present risk assessment are

shown in Table 7-17. Toxicity values are generally based on the level of a chemical

"administered" to a test animal. This situation does not account for the ability of the

animal to absorb the compound into the blood stream. Toxicity values can be adjusted

to account for this factor by incorporating an estimate of the level of absorption which

is likely to occur. In the present risk assessment it was necessary to adjust toxicity

values based on "administered" doses to an "absorbed" dose basis because

contaminant dose estimates calculated for the dermal route of exposure provide an

"absorbed" dose estimate. Thus, all contaminant dose estimates for all dermal

exposure routes were compared to adjusted toxicity values to estimate health risk.

Absorption estimates and critical toxicity values were approved by the Environmental

Criteria and Assessment Office.

Toxicity values are based on a "critical" toxic effect in an animal. These are generally

the most sensitive effects observed (those detected at lowest doses). The critical effects

for the chemicals of potential concern are listed in Table 7-18. In addition, the

uncertainty factor used to develop the reference dose and the U.S. EPA carcinogen

classification for potential carcinogens are also summarized.


7.1.5 Risk Characterization

In this section, estimates of contaminant exposure are compared with toxicity

information to arrive at an estimate of potential human health risk. Two general types

of toxicity endpoints are evaluated for chemicals of potential concern in this

assessment, i.e., cancer and non-cancer effects. Because the assumptions related to

how chemicals produce cancer effects and non-cancer toxicities differ, the methods

employed to qualify these risks also differ. These are described below.

7.1.5.1 Procedures Used to Quantify Health Risk

7.1.5.1.1 Non-Cancer Effects

Estimating the risk of a non-cancer health effect was accomplished by calculating a

hazard quotient. The hazard quotient for a chemical is calculated by dividing the

estimated contaminant dose by the Reference Dose for the chemical as shown below:

Hazard Quotient = Contaminant Dose Estimate (mg/kg-d)Reference Dose (mgykg-d)

For a given exposure pathway, the hazard quotients for all chemicals of potential

concern are added to arrive at a total. This value is referred to as the hazard index

(HI) for the exposure pathway. If the HI (or hazard quotient) exceeds unity (1), there

may be a potential health risk associated with exposure via the particular pathway (or

chemical) evaluated.

7.1.5.1.2 Carcinogenic Effects

The cancer risk value is an estimate of an individuals' lifetime likelihood of developing

cancer over and above the existing background chance of developing cancer. A cancer

risk of lxlO'6, for example, may be interpreted as an increased risk of one in one

million of developing cancer over a person's lifetime. This risk may also be interpreted

on a population basis, to predict that one additional case of cancer may occur in a

population of one million people.

Remedial Investigation Report SECTION 7.1oACS NPL Site, Griffith, Indiana Page 40Revision: DRAFT 20-SEPTEMBER-91

Generally, when the HQs for several contaminants give an additive HI> 1.0. the HQs

are regrouped according to target organ effect or mechanism of action. If the HI for

all chemicals having the same target organ effect is > 1.0. there is a likelihood of the

effect. However, in this risk assessment, there are some chemicals which tended to

exceed an HQ of 1.0. Because these chemicals dominate the HI, regrouping by target

organ effect was not considered necessary.

The cancer risk is estimated by multiplying the estimated contaminant dose by the

slope factor for the chemical as shown below:

Cancer Risk = Estimated Contaminant Dose (mg/kg-d) x Slope Factor (kg-d/mg)

The cancer risks associated with specific chemicals within an exposure pathway are

assumed to be additive. Therefore, cancer risks for individual chemicals are summed

to arrive at a total exposure pathway cancer risk.

7.1.5.2 Qualitative Health Risk Assessment

In addition to the quantitative risk estimates, a qualitative risk assessment was

conducted for lead. Lead is known to be a potent human neurotoxin at very low

exposure levels. There are currently no U.S. EPA approved toxicity values for lead.

Rather, in the interim, until an appropriate toxicity value can be developed for this

metal, the U.S. EPA has been utilizing a new pharmacokinetic model (i.e., Lead

Uptake/Biokinetic) or interim soil cleanup guidelines of 500-1,000 mg/kg soil (OSWERDirective 99355.4-02). Lead exists on-Site at concentrations of 17,000 mg/kg in soils.

At this concentration, for purposes of this assessment, the "Interim Guidance in

Establishing Soil Lead Clean-up Levels at Superfund Sites" was used.

The existing CERCLA standard for lead in soil is based on the 1985 recommendation

of the Centers for Disease Control (CDC). The U.S. EPA OSWER Directive

discusses appropriate lead levels:

"This guidance adopts the recommendation contained in the 1985 Centers for

Disease Control (CDC) statement on childhood lead poisoning and is to be

followed when the current or predicted land use is residential. The CDC1 recommendation states that ...lead in soil and dust appears to be responsible for


blood levels in children increasing above background levels when the concentration

in the soil or dust exceeds 500 to 1000 ppm. Site-specific conditions may warrant

the use of soil cleanup levels below the 500 ppm level or somewhat above the 1000

ppm level."

Based on this recommendation, for purposes of this assessment, a soil-lead

concentration exceeding 500 mg/kg was compared to the soil-lead concentrations on-

Site.

7.1.5.3 Superfund EPA Health Risk Goals

The U.S. EPA has developed program goals for potential health risks estimated from

exposure to contaminants at Superfund sites. For chemicals which may cause non-

cancer health effects, acceptable exposure levels are intended to represent

concentration levels to which the human population, including sensitive subgroups, may

be exposed without adverse effect during a lifetime or part of a lifetime, incorporating

an adequate margin of safety (i.e., a HI of less than 1). For known or suspected

carcinogens, the 1x10-6 risk level is used by U.S. EPA as a "point of departure" for

determining remediation goals. Cancer risks which are between lxlO"6 and 1x10-4 may

or may not be acceptable depending on other risk management factors (e.g., ARARs,

nature of exposure, efficacy of treatment technologies, cost, and others) applicable to

the Site.

7.1.5.4 Public Health Evaluation

Potential health risks were evaluated for contaminant exposures based on two land-use

scenarios; current Site conditions and possible future Site conditions. As part of these

evaluations, risks to groundwater (upper and lower aquifers), surface and subsurface

soils, surface water and sediment, and air (via fugitive dust and volatiles emissions)

were assessed. In addition, the Site was segregated into "areas" (on-Site containment,

off-Site containment, still bottoms and treatment lagoon, and Kapica-Pazmey areas) to

assess location-specific contamination. Potential risks to groundwater downgradient of

the Griffith Municipal Landfill were also evaluated. The risks, based on the

assumptions and conditions provided in this assessment, are discussed below. Tables 7-

19 through 7-37 summarize risks only for chemicals which may contribute substantially

to the total exposure pathway risk. Thus, these tables summarize chemicals associated

with cancer risk greater than 1x10-6 and chemicals associated with hazard quotients

greater than 0.01. Table 7-38 contains population-based risk totals including a multi-

Remedial Investication Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana Page 42Revision: DRAFT 20-SEPTEMBER-91

population assessment for the maximally exposed individual. For a detailed summary

of risk values associated with all chemicals of potential concern, the reader is referred

to Appendix X.

7.1.5.4.1 Summary of Potential Health Risks Based on Current Land Use

Current land use health risks associated with exposure to contaminated Site media

were evaluated for off-Site-residents, trespassers (children who may occasionally play

on-Site), and on-Site workers at the Site. The likelihood of exposure to populations

from any of the pathways in this risk assessment is considered to be low and generally

results in risk estimates that are conservative.

As has been referred to previously in this risk assessment, risks are based on

hypothetical exposure scenarios. The risks quantified are approximations of potential

health hazards that should be viewed on a relative risk basis, rather than on actual risk

basis.

The risks calculated for groundwater were based on samples that were filtered for

metals but not filtered for organics. The unfiltered samples generally result in

sediments (suspended solids) being collected. This point deserves emphasis in .that, the

presence of certain organic chemicals (i.e., those with strong binding affinity to soils;

high Koc) in groundwater samples is likely the result of the incorporation of sediments

into the sample (i.e., the chemical is adsorbed to sediments and not actually in

solution). PCBs for instance, bind (adsorb) strongly to soils and likely have beenintroduced into the groundwater sample as a suspended sediment. It is also important

to note that arsenic, while contributing to groundwater risks, has a maximum detected

concentration on-Site of 43.2 ug/L (Table 7-2) which is lower than the Maximum

Contaminant Level (MCL) Standard of 50 ug/L. The MCL value for arsenic assumes

that drinking water is the only route of exposure to arsenic, and arsenic is the only

chemical of concern.

In this section, health risks have been discussed separately for individual

populations/subpopulations, and combinations of the same to evaluate the maximally

exposed individual.


7.1.5.4.1.1 Potential Health Risks to Off-Site Residents

Off-Site residents were considered to be exposed to contaminants released to

groundwater and air under current land use conditions. Exposure to groundwater was

considered plausible from both the upper and lower aquifers. Exposure to

contaminants in air (fugitive dusts and volatiles emissions) was considered in the risk

estimate for off-Site residents. Total pathway/population risks (cancer and non-cancer)

are summarized in Table 7-38 while Tables 7-19 through 7-22 contain chemical, route-

specific, and total pathway risks for the off-Site populations in consideration of the

current land use exposure assumptions.

Potential risk to children (i.e., exposure to contaminated water from the upper aquifers

while playing) from non-cancer health effects were above a level of concern as

indicated by an exposure pathway HI greater than unity (1). This potential health

threat is primarily the result of dermal exposure to 4-methyl-2-pentanone (54% of the

risk). Several other chemicals of potential concern exceeded a hazard quotient of 1,

including acetone, 1,2-dichloroethene, 2-butanone, ethylbenzene, dimethyl

ethylbenzene, branched alkanes, and non-cyclic acids. 4-methyl-2-pentanone and

acetone combine for a HI which is greater than 80% of the non-cancer hazard. The

primary toxicity associated with these chemicals is liver and kidney effects (see Table 7-

18).

The total cancer risk to children exposed to contaminated groundwater (upper aquifer

only) was calculated to be 1.7x10-2. This exceeds the U.S. EPA 1x10-6 point ofdeparture. Dermal absorption of benzene is the primary route and chemical associated

with this risk although chloromethane, vinyl chloride, methylene chloride,

trichloroethene, tetrachloroethene, bis(2-chloroethyl)ether, PCB, and arsenic were also

determined to exceed the 1x10-6 point of departure (see Table 7-22). Cyclic ketones

(tentatively identified compounds) were considered similar in chemical structure to

isophorone, and the slope factor for isophorone was used to quantitate a cancer risk

value for this TIC group which exceeded 1x10-6. There is substantial uncertainty in

this result since there is no verified slope factor or reference dose for this TIC group.

Isophorone was used as an approximation/representation for this TIC group (see

Section 7.1.2.2 and Table 7-12).

Remedial Investigation Report ' SECTION 7.1.5ACS NPL Site, Griffith, Indiana Pace 44


m The total pathway HI value for off-Site residents exposed to contaminants in air andgroundwater is 2.1. This value takes into consideration ingestion, dermal absorption,

and inhalation (VOCs released from groundwater during household use) of

groundwater from the lower aquifer, and inhalation of fugitive dusts and VOCs in

ambient air (Table 7-38). None of these exposure pathways, when viewed independent

of one another, has a HI greater than 1 nor does any specific chemical have a HQ

greater than 1.

The HI of 2.1 does not take into consideration each chemical's toxic endpoint.

*" Arsenic, barium, manganese, cyclic alcohols (as represented by benzyl alcohol), and

oxygenated alcohols (as represented by ethylene glycol monobutyl ether) contribute to•***'' the cumulative HI of 2.1; this assumes each of these chemicals has the same toxic

endpoint. However, each of these chemicals actually have toxicities that differ (e.g.,

«• arsenic is associated with keratosis and hyperpigmentation via chronic-oral exposure;

chronic oral barium exposure results in high blood pressure, and so on, see Table 7-

». 18). The individual HQs for each chemical is less than unity (1), and because each

chemical of concern has a different toxic endpoint, a cumulative HI greater than 1cannot be calculated. Therefore, there does not appear to be a noncancer concern for

the off-Site adult residential population when evaluating on the basis of toxicity.

The total cancer risk for off-Site adult residents is 4.5x10-4 (Table 7-38). Ingestion of

~ arsenic and bis(2-chloroethyl)ether in groundwater from the lower aquifer contributes

a substantial portion of this risk. Inhalationof several volatile compounds (methylenechloride, 1,1-dichloroethene, chloroform, carbon tetrachloride, trichloroethene, and

* benzene) from ambient air combine for a total cancer risk of 1.6x10-4. Cancer risk

estimates for fugitive dust inhalation did not exceed levels of concern.m

7.1.5.4.1.2 Summary of Potential Health Risks to Trespassers

« Trespassers (children-adolescents gaining unauthorized entrance to the Site) were

assumed to be exposed to contaminants in several media including surface soils at„,. Kapica-Pazmey, surface water and sediment in the wetlands and drainage ditches, and

fugitive dusts and volatiles in ambient air. Table 7-38 provides a summary of hazard

indices and cancer risks for this population. This table indicates that the total hazard

Remedial Investigation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana - Page 45Revision: DRAFT 20-SEPTEMBER-91

indices for all pathways is greater than 1 (1.9x10+1) with most of the concern

attributed to ingestion and dermal absorption of surface soils at Kapica-Pazmey. Total

cancer risks for all pathways assumed to occur for trespassers is 6.3x10-3. This multiple

pathway assessment indicates a cancer risk exceeding the 1.0x10-6 point of departure.

In assessing non-cancer risks for the trespasser scenario, none of the chemical-specific

HQs for inhalation of fugitive dusts nor the HI for the total pathway exceeded or even

approached unity (1) (Table 7-27). Therefore, inhalation of fugitive dusts is not

considered to pose a health hazard to trespassers at the Site. Inhalation of volatiles in

ambient air by Site trespassers had an inhalation HI of 5.3 (Table 7-26). Non-cyclic

acids \TLC group represented by acrylic acid; Table 7-12), and chloroethane, both have

HQs greater than 1, and together make up approximately 83% of the HI (5.3). The

remaining chemicals have individual HQs less than 1 (Table 7-26).

No individual chemical in surface water or sediment had a chemical-specific HQ

greater than 1 (see Tables 7-24 and 7-25). A hazard index of 1.0 was exceeded when

adding chemical-specific HQs (this assumes the additive effects of these chemicals

affect the same target organ) for the surface water pathway. However, there is no

cumulative HI greater than unity when combining chemicals on the basis of similar

toxic endpoints.

The non-cancer risk to trespassers exposed to surface soils at Kapica-Pazmey was

estimated to be 1.3x10 +1 (Table 7-23). The majority of the hazard index was notassociated with a specific chemical. Rather, exposure to a number of contaminants

(i.e., antimony (16%; HQ = 2.1), bis(2-ethylhexyl)phthalate (12%; HQ = 1.6), toluene

(11.1%;-HQ = 1.4), cadmium (10%; HQ = 1.3), ethylbenzene (10%; HQ = 1.3) and

tetrachloroethene (9%; HQ = 1.2)) contributed nearly equal proportions of risk to the

hazard index. These contaminants illicit varying types of toxic effects (refer to Table 7-

18).

As mentioned previously in Section 7.1.5.2, a quantitative .health assessment for lead

could not be made due to a lack of toxicity values approved by the U.S. EPA. Rather,

an interim soil-lead clean-up criteria of 500 mg/kg established by the U.S. EPA for

Superfund sites was used as a qualitative indicator of the health risk associated withlead exposure.


Surface soils at Kapica-Pazmey exceed the 500-1.000 mg/kg interim lead criteria.

Surface soil lead concentrations ranged from 401 mg/kg to 16,200 mg/kg. The average

(arithmetic) concentration was calculated to be 8,300 mg/kg. Lead exposure has been

shown to cause damage to the central nervous system which leads to learning

impairment in young children.

The cancer risk due to trespasser exposure to surface water is 1.6x10-4 (Table 7-24).

Seventy-three percent of this risk is due to dermal contact with PCBs. The surface

water results likely indicate the presence of sediments in the surface water samples as

PCBs absorb' preferentially to solids, particularly those sediments with high organic

content. PCBs are less likely to be in solution, based on this tendency and their low

water solubility. For exposure to sediments, the cancer risk estimate for trespassers is

2.2x10-4 (Table 7-25). Seventy percent of the sediment cancer risk is due to dermal

contact and incidental ingestion of carcinogenic PAHs (1.5x10-4) and 28% is attributed

to dermal absorption and incidental ingestion of PCBs (6.0x10-5).

There is no cancer risk greater than U.S. EPA's point of departure associated with

exposure of trespassers to fugitive dusts (Table 7-27). Inhalation of volatiles by

trespassers on-Site results in a cancer risk estimate of 2.9x10-4 (Table 7-26). Greater

than 90% of this risk is associated with inhalation of 1,1-dichloroethene (highest

exposure point concentration located at the off-Site containment area), chloroform

(highest exposure point concentration located at the off-Site containment area), and

carbon tetrachloride (highest exposure point concentration located at the stillbottoms/treatment lagoon area).

The cancer risk estimate for exposures to Kapica-Pazmey surface soils is 5.7x10-3

(Table 7-23). Approximately 85% of this total is attributed to PCB exposures

(4.8x10-3), primarily via dermal absorption (4.7x10-3). PAHs account for

approximately 13% of the total cancer risk (6.8x10-4).

7.1.5.4.1.3 Summary of Potential Health Risks to On-Site Workers at the Site

Site workers were assumed to be exposed via inhalation to contaminated fugitive dusts

generated at the Kapica-Pazmey location and to volatiles released from subsurface

(buried) waste from various areas located around the Site. The summary of hazard

indices and cancer risks for these pathways is contained in Table 7-38. The HI

estimated for the Site worker is 9.9, which exceeds unity assuming the same toxic

endpoint for the chemicals contributing to the HI. The cancer risk estimated for this

population is 1.6x10-3 (the cancer risk, like the non-cancer risk, is primarily associated

with exposure to volatiles emissions and not fugitive dusts).

The fugitive dust HI for this population is substantially less than 1 and does not pose a

non-cancer health hazard (Table 7-29). The risk to Site workers is primarily from

exposure pathways evaluated for volatiles emissions emanating from buried wastes. In

assessing which chemicals are contributing to the non-cancer risk for inhalation of

volatiles emissions, non-cyclic acids (TIC group), and chloroethane have chemical-

specific hazard quotients that exceeds 1 (Table 7-28). Thus, based on the assumptions

used to evaluate Site worker exposure to chemicals volatilizing in ambient air, there

may be a noncancer, hazard associated with exposure to VOCs in ambient air, and in

particular, chloroethane, and noncyclic acids.

The cancer risk estimated for fugitive dust exposure is much less than the U.S. EPA's

point of departure (Table 7-29). The cancer risk estimate for inhalation of VOCs in

ambient air is 1.6x10-3 (Table 7-28). The majority of this risk is associated with 1,1-dichloroethene (highest exposure point concentration used to model VOC emissions is

from the off-Site containment area), chloroform (highest exposure point concentration

found at the off-Site containment area), and carbon tetrachloride (highest exposure

point concentration located at the still bottoms/treatment lagoon area).

7.1.5.4.1.4 Potential Maximally Exposed Individuals

An off-Site resident was considered to have potential exposure over a 30-year period.

Exposure to this individual (off-Site resident) may be the result of several, cumulative

exposures depending on their individual behavior. For instance, during the 30-year

exposure period, continuous exposure via drinking water from the lower aquifer was


assumed (i.e., ingestion, dermal absorption, and inhalation of VOCs while showering).

In addition, this individual may also be exposed as a child, age 5 to 15, to contaminated

water from the,upper aquifer while swimming in a pool. Thus, this behavioral-based

exposure is additive. The individual may be exposed while trespassing (age 5 to 15)

on-Site which would also be additive.

The subpopulation RMEs are distinctive, in that different contaminant sources and

behaviors (exposures) were assumed. The RMEs have been added, where appropriate,

to evaluate the maximally exposed individual. Table 7-38 identifies the populations,

based on behaviors, that could be considered to result in the maximally exposed

individual.

In one instance, the maximally exposed individual was considered to be an off-Site

resident with exposure as a child to upper aquifer contamination while playing (i.e.,

swimming in a pool). This combination results in a non-cancer health risk of

1.6x10 + 2. Dermal exposure to 4-methyl-2-pentanone while swimming is the

predominant route of exposure and chemical of concern. The cancer risk of 1.7x10-2 is

also due to swimming as a child in upper aquifer groundwater. Benzene and vinyl

chloride make up the majority of this risk estimate.

In a separate example, the maximally exposed individual was thought to have exposure

as an off-Site resident and trespasser. The non-cancer hazard index calculated for this

individual is 2.1x10+1. The primary pathways and chemicals that would result in thisnon-cancer hazard index are associated with exposures while trespassing on-Site.

Similarly, the cancer risk calculated (6.7x10-3) for an off-Site resident who has

additional exposure as a trespasser, is predominantly due to trespasser exposures. See

Section 7.1.5.4.1.2 for further discussion on trespasser health concerns.

Another illustration of the maximally exposed individual combines the off-Site resident

with childhood exposure while swimming in a pool, and while trespassing (playing) on-

Site. The non-cancer hazard index is 1.7x10 + 2 resulting primarily from exposure to

upper aquifer groundwater while swimming (see Section 7.1.5.4.1.1). Nearly 71% of


the total cancer risks for this individual (2.4x10-2) is also the result of exposure as a

child while swimming in a pool containing contaminated groundwater from the upper

aquifer (see Section 7.1.5.4.1.1).

Finally, the maximally exposed individual was considered to possibly be exposed as an

off-Site resident who also works at the Site. A hazard index of 1.2x10 + 1 and cancer

risk of 2.1x10-3 were estimated for this individual. Inhalation of VOCs as a Site

worker was the primary route of exposure associated with both the HI and cancer risks

(see Section 7.1.5.4.1.1 for discussion of chemicals contributing to these estimates).

7.1.5.4.2 Summary of Potential Health Risks Based on Future Land Use

Future land use health risks associated with exposure to contaminated Site media were

evaluated for residents living on-Site. The future land use scenario assumed

hypothetically, that a residential development may be plausible at the Site. This

coincides with recent guidance and is required by the U.S. EPA RPM and U.S. EPA

Technical Support Group. The likelihood of this type of occurrence in unknown but,

is considered to be quite low.

7.1.5.4.2.1 Potential Health Risks to Hypothetical Residents Living Qn-Site

To address potential health risks due to contamination associated with operable areas

of the Site (e.g., on-Site containment area, Kapica-Pazmey area, off-Site containment

area, and the still bottoms/treatment lagoon area), a resident was assumed to exist at

each of these locations, and be exposed to the contaminated soils at each locationindependent from the other areas. For example, a resident is assumed to have their

home on the on-Site containment area and is exposed to the soils at this location only.

Risks associated with other media (for exposures to contaminants in surface water and

sediments, groundwater, and air) for a resident residing at the on-Site containment

location are the same as that for a resident assumed to have their home at the other

areas. Therefore, the only difference in risks at the Site is associated with exposure to

soils from each area. This approach was taken to assess the soils on a localized basis

rather than on a Site-wide basis and to facilitate analysis in the Feasibility Study.

Remedial Investieation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana Pace 50Revision: DRAFT 20-SEPTEMBER-91

Total pathway risks (non-cancer and cancer) are summarized in Table 7-38 for each of

the populations residing at the different areas. Tables 7-24. 7-25, and 7-30 through 7-

37 contain chemical-specific, route-specific, and total pathway risks for the hypothetical

residents.

Exposure to groundwater was assumed to occur from both the upper and lower

aquifers, nonconcurrently (i.e., residents had a well in either the lower or upper aquifer

- not both at the same time). For purposes of this discussion, only the upper aquifer is

addressed because the risks associated with exposure to it were greater than that of the

lower aquifer.

The non-cancer health risk for a hypothetical resident (regardless of location on-Site)

exposed to contaminated groundwater in the upper aquifer was estimated to be

3.3x10 + 2 (Table 7-31). This assumes that each chemical of concern has the same toxic

effect.

Approximately 47% of the HI is due to exposure to 2-butanone (HQ of 1.6x10 + 2);

23% to 4-methyl-2-pentanone (HQ of 7.6x10+1), and 14% to non-cyclic acids (HQ of

4.6x10 +1; TIC group represented by acrylic acid). 2-Butanone toxicity via inhalation

is manifested by central nervous system effects, and fetotoxic effects based on oral

studies on rats (Table 7-18).

Exposure to surface water and sediments for on-Site residents was assumed to be

similar to that of Site trespassers under the current land use scenario that is, on an

occasional basis. The total surface water HI was calculated to be 1.3 (Table 7-24),

which assumes similar toxic endpoints for the chemicals of concern contributing to the

HI. A HI of 1 is not exceeded when evaluating chemicals based on each chemicals

toxic endpoint; therefore, there does not appear to be a non-cancer health concern

related to surface water exposure. The HI for sediments is less than unity even when

assuming conservatively that the chemicals of concern have the same toxic effect, and

thus, exposure to sediments is not considered to pose a non-cancer health hazard to

future on-Site residents.

Remedial Investigation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana . Page 51Revision: DRAFT 20-SEPTEMBER-91

The non-cancer HI value for inhalation of VOCs in air is 1.6x10+ 1. The majority of

this HI value is associated with non-cyclic acids (47%). Non-cyclic acids (HQ of 7.7)

and chloroethane (HQ of 5.9) comprise approximately 83% of this HI value. These

are the only chemicals of .potential concern associated with inhalation of VOCs in

ambient air with HQs greater than 1.

The non-cancer HI values for potential on-Site residents associated with subsurface

soils from each of the areas is summarized below and in Tables 7-33 through 7-37.

• On-Site Containment Area

- The total pathway HI value for exposures to subsurface soils assumed to beunearthed for residential development and brought to the surface is5.0x10+1 (Table 7-33) based on similar toxicities. Several chemicals exceedunity by themselves (i.e., HQ > 1), and tend to drive the HI result (see Table7-18 for toxic endpoints for chemicals of concern).

- 47% of this value is associated with tetrachloroethene, 32% with toluene,and 11% with ethylbenzene. Only two other chemicals of potential concernhad HQ values greater than 1; naphthalene and bis(2-ethylhexyl)phthalate(Table 7-33).

• Still Bottoms/Treatment Lagoon Area

- The total pathway HI for exposure to subsurface soils at the stillbottoms/treatment lagoon area was estimated to be 4.1x10 + 2 (Table 7-34).Because this value exceeds unity, it may be interpreted to mean that there isa potential non-cancer health concern associated with subsurface soilexposure in this area. This is because some chemicals have HQ values thatexceed unity.

- 58% of this value is associated with carbon tetrachloride (HQ of 2.4x10 + 2),7% with n-chain alkanes (HQ of 3.0x10+1), and 10% with nitrogenatedbenzenes (HQ of 3.9x10 +1) (Table 7-34).

- Other chemicals with HQ values greater than 1 include: 1,2-dichloroethene(cis), chloroform, l,l,l-trichloroethane,4-methyl-2-pentanone,tetrachloroethene, toluene, ethylbenzene, isophorone, naphthalene,hexachlorobutadiene, bis(2-ethylhexyl)phthalate, endosulfan I, 4,4'DDT,antimony, cadmium, methyl propyl benzenes, dimethyl ethyl benzenes,halogenated alkanes and branched alkanes. Numerous other chemicals ofpotential concern approach a HQ of 1.

• Off-Site Containment Area

- Table 7-35 contains a summary of HQs for chemicals of potential concern atthe off-Site containment area. A total pathway HI value (based on similartoxic endpoints) of 1.0x10 + 3 was calculated.

Remedial Investigation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana Page 52Revision: DRAFT • 20-SEPTEMBER-91

- The following chemicals were determined to contribute substantially to thepotential hazard: tetrachloroethene - 18% (HQ of 1.8x10 + 2), 2-but'anone -15% (HQ of 1.6x10 + 2), nitrogenated benzenes (TIC group) - 15% (HQ of1.6x10 + 2), bis(2-ethylhexyl)phthalate - 11% (HQ of 1.1x10 + 2). 4-methyI-2-pentanone - 9% (HQ of 9.6x10+1), 1,1,1-trichloroethane - 7% (HQ of66x10+1), cadmium - 3% (HQ of 3.3x10+ 1), and naphthalene 3% (HQ of2.8x10 + i).

- Besides the chemicals above, 24 additional chemicals of potential concernhad a HQ greater than 1.

• Kapica-Pazmey Area (Surface Soils - assuming no excavation for residentialdevelopment)

- The total pathway HI value for exposures to surface soils is 3.4x10+ 1 (Table7-36). Because the HI exceeds unity there may be a potential non-cancerhealth risk associated with exposure to Kapica-Pazmey surface soils. Again,

- this is possible because several chemicals of concern, in and of themselves,have a HQ value which exceeds unity.

- A single chemical did, not overwhelmingly contribute to the cumulative HI,rather a number of compounds had HQs of 1 to 2 which together,contributed nearly equal proportions of risk. The following metals andorganic compounds have HQ values that exceed 1 (Table 7-36): Metals -antimony, barium, cadmium, and chromium; Organics - tetrachloroethene,toluene, ethylbenzene, naphthalene, and bis(2-ethylhexyl)phthalate.

• Kapica-Pazmey Area (Subsurface Soils and Surface Soils-Mixed)

- The total pathway HI value for exposures to mixed soils is 4.2x10 + 2 (Table7-37).

- As with Kapica-Pazmey surface soils, the majority of the pathway risk is notattributed to a single chemical. Rather, a number of chemicals had HQs of 1to 2 which contributed to the cumulative HI (Table 7-37). Also, becauseseveral chemical-specific HQs exceeded unity, it was not necessary to regroupthe chemicals based on toxic endpoints. Refer to Table 7-18 for toxic effectsassociated with those chemicals determined to provide the greatest potentialhazard.

- Antimony, barium, cadmium, and chromium had individual HQs greater than1. Tetrachloroethene, toluene, ethylbenzene. naphthalene, and bis(2-ethylhexyl)phthalate also had HQ values greater than unity.

The highest total pathway, non-cancer risk for a hypothetical resident at the Site is

associated with residential development at the off-Site containment area. The still

bottoms/treatment lagoon area has the next highest hazard index followed by Kapica-

Pazmey surface soils and Kapica-Pazmey soils (all depths), and finally the on-Site

containment area. The difference in the noncancer risk between these areas is no

greater than a factor of approximately 3.5.

Remedial Investigation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana Page 53Revision: DRAFT . 20-SEPTEMBER-91

Similar to current Site conditions, a qualitative health assessment was conducted for

soil-lead exposure. In each of the areas considered (i.e., On-Site Containment. Still

Bottoms/Treatment Lagoon, Off-Site Contaminant, and Kapica-Pazmey) soil-lead

concentrations exceeded the 500 -1,000 mg/kg interior soil-lead clean-up criteria set by

the U.S. EPA. Concentrations of lead on average (arithmetic) were highest at Kapica-

Pazmey (8,300 mg/kg), the Off-Site Containment area (1,100 mg/kg), and Still

Bottoms/Treatment Lagoon (840 mg/kg) areas. Average soil-lead concentrations in the

On-Site Containment area where substantially less than the other areas (i.e., 110

mg/kg).

For purposes of this discussion, cancer risks estimated for hypothetical residents have

been evaluated in the same fashion as non-cancer risks. That is, the cancer risks

estimated for groundwater, surface water and sediment, and air are the same for a

hypothetical resident regardless of the location on-Site. Risks estimated for exposure

to soils has been evaluated on a location-specific basis.

Cancer risks estimated for exposure to groundwater are greatest in the upper aquifer.

The cancer risk associated with groundwater exposure is approximately 8.7x10-2. This

is well in exceedance of the U.S. EPA's 1x10-6 point of departure. Chemicals which

contribute to this risk are provided in Table 7-31. As is evident in this table, nearly

61% of the risk is associated with dermal absorption, inhalation, and ingestion of

benzene in groundwater. Numerous other chemicals of potential concern exceed the

1x10-6 point of departure (see Table 7-31).

Cancer risk estimates for occasional exposure to surface water and sediment is

contained in Tables-7-24 and 7-25. Cancer risks due to surface water exposure were

estimated to be 1.6x10-4. Dermal contact with PCBs (likely absorbed on sediment)

accounts for approximately 73% of this risk estimate. The permeability constant for

PCBs is based on PCBs not bound to sediments. Thus, this result likely over-estimates

the PCB risk. Benzene, bis(2-chloroethyl)ether, and arsenic also exceed the 1x10-6

point of departure for surface water exposure. Sediment exposures result in a cancer

risk estimate of 2.2x10-4. In this instance, carcinogenic PAHs and PCBs combined,

comprise nearly 100% of the risk estimate (Table 7-25).

Remedial Investigation Report SECTION 7.1.5ACS NPL Site, Griffith, Indiana Pace 54Revision: DRAFT • 20-SEPTEMBER-91

Inhalation of VOCs in ambient air emanating from buried wastes at the Site results in

a cancer risk estimate of 2.7x10-3. As is evident in Table 7-32, most of this risk is

associated with 1,1-dichloroethene, carbon tetrachloride. and chloroform. Other

chemicals of potential concern also exceed the U.S. EPA point of departure (see Table

7-32). -

The cancer risk estimates for soils at the various locations on-Site are summarized

below and in Tables 7-33 through 7-37.

On-Site Containment Area

- The cancer risk estimated for exposure to subsurface soils at the on-Sitecontainment area is 6.8x10-3 (Table 7-33).

- 76% of this risk is due to tetrachloroethene, 15% to PCBs, and 5% tobenzene. Several other chemicals of potential concern exceed the 1x10-6point of departure.

• Still Bottoms/Treatment Lagoon Area

- Cancer risk estimated for the subsurface soils in this area is 3.8x10-2 (Table7-34).

- The majority of this risk is attributable to PCBs (48%), carbon tetrachloride(24%), bis(2-chloroethyl)ether (11%), bis(2-ethylhexyl)phthalate (6%), andtetrachloroethene (4%).

- Numerous other chemicals of potential concern exceed the U.S. EPA 1x10-6point of departure.

• Off-Site Containment Area

- Table 7-35 indicates a cancer risk estimate for exposure to subsurface soils inthe off-Site containment area of 1.5x10-1.

- Chemicals of potential concern that contribute substantially to this riskinclude PCBs, tetrachloroethene, PAHs, bis(2-ethylhexyl)phthalate, 1,4-dichlorobenzene, 1,1-dichloroethene, and trichloroethene. There are severalother chemicals of potential concern besides these that have cancer valuesexceeding the 1x10-° point of departure (see Table 7-35).

• Kapica-Pazmey (Surface Soils - assuming no excavation for residentialdevelopment)

- A cancer risk value estimated for exposure ,to surface soils in the Kapica-Pazmey area is 4.5x10-2 (Table 7-36).


- 85% of this risk is estimated to be the result of PCB exposure from thesesoils. 12% is from PAH exposure. Other chemicals of potential concern insurface soils fromMiis area resulted in cancer risks exceeding the U.S. EPApoint of departure (see Table 7-36).

• Kapica-Pazmey (Subsurface Soils and Surface Soils - Mixed)

- Exposure to subsurface soils from Kapica-Pazmey results in a cancer risk of1.8x10-2 (Table 7-37).

- PAHs and PCBs combine for 91% of the risk estimate. Several otherorganics and inorganics in soils at this location also exceed the 1x10-6 pointof departure (Table 7-37).

The multiple exposure assessment indicates that cancer risk appears to be greatest for

a resident residing at the off-Site containment area (2.9x10-1). A factor of

approximately 2.4 separates the cancer risks from the five areas evaluated.

7.1.5.5 Uncertainties in the Risk Assessment Process

The risk assessment process incorporates numerous assumptions and is therefore

associated with a great deal of uncertainty. Thus, calculated risk estimates are not to

be construed to necessarily represent actual risks. Proper interpretation of health risk

values requires consideration of the uncertainties and assumptions involved in the risk

calculations.

The risk assessment uses hypothetical scenarios and conservative assumptions to

quantify potential risks for current and future land uses which do not necessarily, but

could, reflect actual risks. However, assumptions used in this assessment are an

attempt to characterize a reasonable hypothetical useage.

Assumptions are applied in all steps of the process including Site contaminant

characterization, exposure assessment, toxicity assessment, and risk characterization.

These assumptions may over- or under-estimate risks. Examples of some key

uncertainty factors and assumptions applied in the risk assessment are described below,

as well as indications of their biases.

Assume Site is fully characterized. The presence of areas of contamination notidentified may result in an under-estimation of Site risks.

Assume identified chemicals are associated with the majority of Site healthrisks. The presence of highly toxic compounds not analyzed for or identifiedcompounds for which little toxicity information exists (e.g., tentativelyidentified compounds) may result in an under-estimation of Site risks.

Evaluating potential current and future risks (e.g., private well users and futureresidents) without consideration of the likelihood with which these scenariosmay occur over-estimates actual risks.

Toxicity values may over-estimate risk. Reference doses incorporateconservative uncertainty factors and cancer slope factors estimate upper bound95th percentile values.

Risks/doses within an exposure route assumed to be additive. This may resultin an over- or under-estimation of risk because using this approach does nottake into account antogonistic or synergistic effects.

Critical toxicity values derived primarily from animal studies may over- orunder-estimate risk. There is a fundamental uncertainty in extrapolatinganimal toxicity data to humans. Several factors may introduce the uncertaintyincluding differences in species, absorption characteristics, pharmacokinetics,target organs, etc.


• Behavioral patterns cannot be predicted with certainty. The ExposureAssessment Section identifies numerous assumptions that are applied tocharacterizing populations and their potential for exposure to Sitecontaminants.

• Models used to predict environmental fate and transport of contaminants mayover- or under-estimate risk. The air pathway models used have inherentuncertainty in their theoretical ability to accurately predict air concentrationsof contaminants.

' • Identification of tentatively identified compounds. The associated value is anestimated quantity in which there is presumptive evidence of the presence ofthe material (tentative identification).

• Other major assumptions used in the risk assessment that would tend to over-estimate Site risks include:

- There are no groundwater use restrictions.

- There is the potential for future development of the Site.

• Contaminant concentrations in various media are assumed to remain constantover time (As was noted previously for this assumption, this may result in anover- or under-estimation of exposure because using steady-state conditionsdoes not account for substantial future releases of unmitigated source materials(e.g., to groundwater) that may occur over time, nor does it account for sourcedepletion and attenuation of materials through environmental fate andtransport processes).

This table includes all compounds identified above detection limits in the Upper Aquifer Source Area (see table 7-1 forsamples included in this area), and is provided as the starting point in the development of a Set of Chemical Data foruse in the Risk Assessment, as discussed in Section 7.1.2.1. Refer to appropriate appendices to determine the totalparameters analyzed and their associated detection limits. Refer to appendix U for values used in risk calulations.The data values presented contain a maximum of three significant digits for the results of metals analyses and twosignificant digits for organic chemical analyses: additional digits are due to limitations in the computer program usedto prepare these tables, and do not infer an increase in accuracy. The number of tentatively identified compoundsdesignated as unknowns may exceed the total number of samples analyzed because more than one unknown compound may bepresent in a given sample.

This table includes all compounds identified above detection limits in the lower Aquifer Source Area (see table 7-1 forsamples included in this area), and is provided as the starting point in the development of a Set of Chemical Data foruse in the Risk Assessment, as discussed in Section 7.1.2.1. Refer to appropriate appendices to determine the totalparameters analyzed and their associated detection limits. Refer to appendix U for values used in risk calulations.The data values presented contain a maximum of three significant digits for the results of metals analyses and twosignificant digits for organic chemical analyses: additional digits are due to limitations in the computer program usedto prepare these tables, and do not infer an increase in accuracy. The number of tentatively identified compoundsdesignated as unknowns may exceed the total number of samples analyzed because more than one unknown compound may bepresent in a given sample.

This table includes all compounds identified above detection limits in the Stillbottoms/Treatment Lagoon Area (see table7-1 for samples included in this area), and is provided as the starting point in the development of a Set of Chemical Datafor use in the Risk Assessment, as discussed in Section 7.1.2.1. Refer to appropriate appendices to determine the totalparameters analyzed and their associated detection limits. Refer to appendix U for values used in risk calulations.The data values presented contain a maximum of three significant digits for the results of metals analyses and twosignificant digits for organic chemical analyses: additional digits are due to limitations in the computer program usedto prepare these tables, and do not infer an increase in accuracy. The number of tentatively identified compoundsdesignated as unknowns may exceed the total number of samples analyzed because more than one unknown compound may bepresent in a given sample.

This table includes all compounds identified above detection limits in the Off-Site Containment Area (see table 7-1 forsamples included in this area), and is provided as the starting point in the development of a Set of Chemical Data foruse in the Risk Assessment, as discussed in Section 7.1.2.1. Refer to appropriate appendices to determine the totalparameters analyzed and their associated detection limits. Refer to appendix U for values used in risk calulations.The data values presented contain a maximum of three significant digits for the results of metals analyses and twosignificant digits for organic chemical analyses: additional digits are due to limitations in the computer program usedto prepare these tables, and do not infer an increase in accuracy. The number of tentatively identified compoundsdesignated as unknowns may exceed the total number of samples analyzed because more than one unknown compound may bepresent in a given sample.

This table includes all compounds identified above detection limits in the Kapica-Pazmey Area soil samples collected ata depth of less than 3 feet(see table 7-1 for samples included in this area), and is provided as the starting pointin the development of a Set of Chemical Data for use in the Risk Assessment, as discussed in Section 7.1.2.1.Refer to appropriate appendices to determine the total parameters analyzed and their associated detection limits.Refer to appendix U for values usecj in risk calulations. The data values presented contain a maximum of threesignificant digits for the results of metals analyses and two significant digits for organic chemical analyses:additional digits are due to limitations in the computer program used to prepare these tables, and do not inferan increase in accuracy. The number of tentatively identified compounds designated as unknowns may exceed thetotal number of samples analyzed because more than one unknown compound may be present in a given sample.

This table includes all compounds identified above detection limits in the sediment samples (see table 7-1 forsamples included in this area), and is provided as the starting point in the development of a Set of Chemical Data foruse in the Risk Assessment, as discussed in Section 7.1.2.1. Refer to appropriate appendices to determine the totalparameters analyzed and their associated detection limits. Refer to appendix U for values used in risk calulations.The data values presented contain a maximum of three significant digits for the results of metals analyses and twosignificant digits for organic chemical analyses: additional digits are due to limitations in the computer program usedto prepare these tables, and do not infer an increase in accuracy. The number of tentatively identified compoundsdesignated as unknowns may exceed the total number of samples analyzed because more than one unknown compound may bepresent in a given sample.

Definitions of chemical properties:

Water Solubility is the maximum concentration of a chemical thatdissolves in pure water at a specific temperature and pH. Values are •given for a neutral pH and a temperature range of 20 degrees C.The rate at which a chemical is leached from a waste by infiltratingprecipitation is a function of its solubility in water. The moresoluble compounds are expected to be leached much more readily andrapidly than less soluble chemicals. The water solubilitiespresented in the literature indicate that, in general, the volatile organicchemicals are more water soluble than the many semi volatileorganic compounds (e.g., PAHs, PCBs).

Vapor pressure (VP) provides an indication of the rate at which achemical in its pure state volatilizes. Values are given for a temperaturerange of 20 to 30 degrees C. VP is of primary significance whereenvironmental interfaces such as surface soil/air and surface water/airoccur. Volatilization is not as important when evaluating groundwater andsubsurface soils. Chemicals with higher vapor pressures are expectedto enter the atmosphere more readily than chemicals withlower vapor pressures. Vapor pressures for monocyclic aromatic (toluene)and chlorinated aliphatics (TCE) are generally many times higherthan vapor pressure for phthalate esters (bis(2-ethylhexyl)phthalate),polynuclear aromatic hydrocarbons (PAHs), and pesticides.

Organic Carbon Partition Coefficient (Koc) is a measure of thetendency for organics to be adsorbed by soil and sediment and is expressedas:

mg chemical adsorbed/kg organic carbonKoc =

mg chemical dissolved/liter of solution

The Koc is chemical specific and is largely independent of soil

properties. In general, the Koc is inversely related to its environmental mobility

Yes

Surveys performed at homes adjacent to theSite indicate those with wells in the shallowaquifer do not use them for drinking water;the municipal system is used.

Some homes adjacent to the Site maintainwells in the upper aquifer and use the waterfor lawn care and gardening. If contaminatedgroundwater were to migrate to the off-Sitewells, exposure may be possible for gardenproduce and subsequent human consumption. Inaddition, children may play in the water(e.g., in swimming pools) and become exposeddermally or through incidental ingestion.However, no testing was performed for thesewells because they are not used for drinkingwater and because if contamination werefound, it would be difficult to determine thesource, in a region where there exists manyindustries. Also, the flow of groundwater inthe upper aquifer is diverted towards theexcavation near the active landfill and bythe wetlands which surround the Site, bothserving to control off-Site migration ofcontaminants. Nonetheless, if contaminantsin the shallow aquifer migrate to off-Sitelocations, residents adjacent to the Site mayoccasionally be exposed, therefore, thispathway was included in the risk assessment.

Eight private wells located in the deepaquifer were analyzed during the RI and hadno detectable levels of contamination. TheACS and landfill facilities both maintainwells in the lower aquifer; the landfillfacility uses their well for drinking water,the use of the well at ACS is for industrialpurposes as well as drinking water. There isretardation of contaminant migrationvertically due to the confining layer. Thepotential for exposure to the groundwater inthe lower aquifer is considered to be low.Nonetheless, contaminants detected in thelower aquifer were assumed to migrate to off-Site locations where exposure may occur.

The amount of VOCs eminating from thecontaminated soils is expected to be lowcompared to that from the ACS facility andfrom the air in this region of heavyindustry. No samples were taken in the fieldbecause of the difficulty in distinguishingair pollutant sources and anthropogenicbackground. It should be recognized thatvolatiles released from the Site may pose anexposure to off-Site residents. Predictingthe amount of exposure quantitatively wouldbe difficult given the current conditions.Nonetheless, an emission and dispersion modelwas used to estimate potential releases toair from subsurface contamination.

There exist unvegetated areas of surface soilcontamination at Kapica/Pazmey. These soilsmay be disturbed via wind erosion anddisperse contaminated particulates to off-Site locations: The greatest impact islikely to be on-Site. A particulate erosionand dispersion model has been used toestimate exposure from this pathway.

This pathway was not considered to presentsubstantial risk.

The wetlands do not support fish populations.Hunting and trapping are considered lowpotential exposure pathways because of smalluser groups.

Similar to off-Site residents, estimatingexposure via this pathway under currentconditions utilized an emissions anddispersion model.

Wind erosion may contribute to the totalexposure for a trespasser coming on-Site atKapica/Pazmey.

Surface contamination is evident atKapica/Pazmey. Children playing(trespassing) on-Site at this location may beexposed occasionally via the pathwaysindicated. Other areas of the RI/FS Sitewhere contaminated soils exist are coveredwith clean material and/or have extremeaccess limitations (i.e., ACS).

This pathway is evaluated to assess the risksassociated with surface water and sediment.Contamination has been detected in thesemedia.

Contaminated soils and sediments have beencovered by clean cover material and/or,building construction. The surface water inthe lagoon has been analyzed and indicateslow contamination. The lagoon is the onlysurface water feature on the Site. Inaddition, workers on-Site wear health andsafety protection, and must comply with OSHAsafety requirements.

Contaminated soils are covered by clean coyermaterial effectively minimizing the potentialfor generation of contaminated fugitive dust.Volatiles released from subsurface soils tothe ambient air may occur, however, exposureto volatiles released from operatingprocesses is likely more substantial.Analysis of volatiles released fromsubsurface soils has not been performedbecause of the difficulty in obtainingmeaningful estimates of exposure pointconcentrations given the contributions ofpollutants to the air from the ACS facilityand anthropogenic background. Nonetheless,emissions and dispersion models have beenused to estimate release of volatilecontaminants from subsurface materials to theair.

ACS maintains 4 wells in the deep aquifer,more than 300 ft below the ground surface, inbedrock.

NOTES:

1) A reference dose (RFD) is derived from a pertinent toxicity study(s), and is an estimate of the "safe" level of chemicalintake over a set length of exposure (e.g., chronic) for humans. Many assumptions must be made when predicting tins "safe"chemical intake level (i.e., RFD) from a laboratory study. Uncertainty factors (UFs) are applied when estimating the RFOfor the following reasons.

• A UF of 10 is used to account for variation in the general population and is intended to protect sensitivesubpopulations (e.g., elderly, children).

A UF of 10 is used when extrapolating from animal data to humans. This factor is intended to account for theinterspecies variability between humans and other mammals.

A UF of 10 is used when a RFD is derived from a subchronic instead of a chronic toxicity study.

• A UF of 10 is used when a lowest adverse effect level (LOAEL) is used instead of a no adverse effect level (MOAEL) toderive a RFD. This factor is intended to account for the uncertainty associated with extrapolating from toxic levels ofchemical exposure (i.e., LOAEL) to nontoxic. levels of chemical exposure (i.e., NOAEL).

In certain cases, a modifying factor (MF) is used to account for further uncertainty associated with the toxicity studyused to develop the RFD, The MF may vary from >0 to 10.

The uncertainty factors presented in this tabje represent the product of all the uncertainty factors (and modifyingfactors) used to derive the RFD (e.g., 10x10x10 = 1000).

2) This code represents the U.S. EPA weight-of-evidence classification system for carcinogenicity for chemicals. The followingis a description of the classification by group.

Group Description

A Known human carcinogen

Bl or B2 Probable human carcinogen

Bl indicates that limited human data on the carcinogenicity of the chemical are available.

B2 indicates sufficient evidence of carcinogenicity in animals and inadequate or noevidence of carcinogenicity in humans exists.

C Possible human carcinogen

D Not classifiable as to human carcinogenicity

E Evidence of noncarcinogenicity for humansi

3) The slope factor for benzo(a)pyrene was used to represent the carcinogenic potential of the carcinogenic polynucleararomatic hydrocarbons (PAHs).

4) Toxicity values have been developed separately for ingestion of cadmium in water and cadmium ingestion with solids (i.e.,food or soil).

5) Tentatively identified compounds (TICs) were grouped based on similar chemical structure. Compounds of similar chemicalstructure are assumed to have similar toxicological properties. For each TIC grouping, a representative compound waschosen for which there was a reference dose (RFD). The RFD for the representative compound was used to represent the toxicpotential of the particular TIC group.

6) The information in this table was summarized from U.S. EPA's "Health Effects Assessment Summary Tables" (Fiscal Year -Annual, 1991).

This table presents risk values for chemicals of potential concern which are associated with hazard quotientsgreater than 0.01 or cancer risks greater than 1.0e-06. Chemicals of potential concern with risk values lessthan both of these levels are not shown.

Hazard quotients and cancer risks are unitless values which represent the probability of incurring an adversehealth effect. These risk values are calculated using the following relationships:

Hazard Quotient = Chronic Daily Intake / Reference DoseCancer Risk = Chronic Daily Intake x Slope Factor

Hazard quotients and cancer risks are summarized for applicable routes of exposure. Values for each route aresummed to arrive at an exposure pathway total risk value. The percentage of total risk is also shown for each compound.

In some cases risks were not determined (ND) because reference doses or slope factors were not available.

Notes:

Toxicity values were obtained from the U.S. EPA's Integrated Risk Information System (IRIS), U.S. EPA's "Health Effects AssessmentSummary Tables" (HEAST, Annual FY-1991), and information provided by U.S.EPA Environmental Criteria Assessment Office (ECAO).Toxicity values for the TIC groupings are values for the representative compounds.

Chemical specific information pertaining to the oral and dermal absorption of compounds was provided by ECAO. In theabsence of chemical specific values, it was assumed that the oral absorption efficiency for organic compounds and metalswas 50 X and 5 X, respectively. The dermal absorption estimates were assumed to be 30% for organic compounds and 1.0 Xfor metals. The oral and dermal absorption estimates are presented as unitless values where 1.0 represents 100 X (complete)absorption.. Chemical-specific dermal permeability constants were obtained from the U.S. EPA "Superfund ExposureAssessment Manual" (SEAM) 1988, or the ECAO. As required by the U.S.EPA, when chemical-specific information is not available,default values were assigned to represent chemical permeability, as footnoted.

Reference Doses and Slope Factors designated for the dermal route of exposure are not provided in the U.S. EPA information sources,but were calculated from corresponding values for the oral route of exposure. These values are used to calculate risksassociated with chemical dose estimates based on an absorbed (in contrast to an administered) level of chemical. All chemicaldose estimates for the dermal route of exposure are based on absorbed chemical levels. The following relationships wereused to derive dermal toxicity values:

Oral Reference Dose (administered) x Oral Absorption Estimate « Dermal Reference Dose (absorbed)Oral Slope Factor (administered) / Oral Absorption Estimate = Dermal Slope Factor (absorbed)

(*) Total population hazard indices and cancer risks for future Site residents were calculated byincorporating values for groundwater in the upper aquifer. »

(1) In addition to the current use exposures that exist for each population as described above, it ispossible that a trespasser may also be an off-Site resident, and on-Site workers may be an off-Siteresident. Thus, while pathways have been combined for each individual population, populations havealso been combined, as appropriate (e.g., off-Site resident and trespasser) to evaluate the maximumexposure of a population through current land use conditions that is reasonably expected to occur atthe Site.

(2) The amount of exposure time to contaminants in air as a trespasser (3 hours/day, 52 days/year, 10years) is 1.2% of the off-Site resident (24 hours/day, 182 days/year, 30 years). Because making thisadjustment does not significantly alter the total multi-population risk, individual population riskswere directly added in o'rder to evaluate maximally exposed population risks.

(3) Similarly, ACS exposure to contaminants in air while working on-Site (8 hours/day, 130 days/year, 30years) is 23.8% of the exposure conditions assumed for the off-Site resident (24 hours/day, 182days/year, 30 years). This difference does not have a substantial impact on the total, multi-population risk. Individual population risks were directly added in order to evaluate maximallyexposed population risks.
