1.0 INTRODUCTION AND PROJECT ORGANIZATION

1.1 PROJECT DESCRIPTION

The Fibers Public Supply Well Field is located on the south side of Route 3 in Guayama, Puerto Rico. Figure 1.1-1 is a general index map of Puerto Rico showing the approximate location of the well field. The specific locations of the supply wells are indicated on Figure 1.1-2. Four of the five supply wells have been shut-down by the operator, the Puerto Rico Aqueducts and Sewer Authority (PRASA), as a result of reported contamination. Water samples collected from the wells in 1983 by the United States Environmental Protection Agency (USEPA) showed elevated levels of volatile organic compounds in the four wells that were shut-down. The wells have been included on the National Priorities List (NPL) of known and threatened releases of hazardous substances.

The general hydrogeologlc setting of the site is described as colluvial fan deposits gently sloping to the south. The deposits consist of stratified sands, gravels and clays with reported thicknesses up to about 125 feet. Ground water is observed at the site at depths between 10 and 20 feet below land surface.

Studies performed by the United States Geological Survey (USGS) indicate that the Fibers Public Supply Wells are located downgradient of an industrial facility currently operated by Ayerst-Wyeth Pharmaceuticals, Inc. , a subsidiary of American Home Products (AHP). This facility had been operated from 1966 to 1980 by subsidiaries of Phillips Petroleum Company and Chevron Chemical Company. During this period of time, wastewater from the facility was stored in two lagoons located on the north side of Route 3. A third adjacent lagoon to the west was utilized for storm water management. The USEPA believes the two wastewater lagoons are the source of the contamination at the PRASA wells. In 1985, the three lagoons were modified by AHP to provide a single storm water management facility.

Phillips and Chevron have voluntarily entered into an agreement with the USEPA to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the site. The general purposes of this RI/FS are: to confirm the presence, nature and extent of contamination; to identify the sources of contamination to evaluate alternatives and recommend a cost-effective remediation plan that will provide protection of the public health and welfare, and the environment.

M Additional information pertaining to the requirem.ents for conducting ^

the RI/FS at the site is included in the USEPA Administrative Order, Index No. II - CERCLA 50301, and in a document entitled "Work Plan, Remedial In- ° vestigation/Feasibility Study, Fibers Public Supply Well Field, Guayama, ^ Puerto Rico," dated October 1985.

It is the purpose of this Site Operations Plan (SOP) to provide a detailed guide and schedule for the RI activities to be implemented at the site, to develop a Quality Assurance and Quality Control (QA/QC) methodology for these activities, and to establish a site-specific Health and Safety Plan (HSP).

Chapter 2, SITE ACTIVITIES GUIDE, describes the purpose of the activities, and provides a detailed list of equipment and procedures to accomplish each activity. Chapter 3, SITE ACTIVITIES SCHEDULE, outlines the anticipated schedule of the activities detailed in Chapter 2.

Chapter 4, SITE SPECIFIC QUALITY ASSURANCE/QUALITY CONTROL DOCUMENT, has been prepared as a stand-alone document as well as an integral part of the SOP. This chapter develops the QA/QC methodologies for the site activities and for the laboratory analyses.

Chapter 5, HEALTH AND SAFETY PLAN, has also been prepared as a standalone document as well as an integral portion of the SOP. This chapter provides the work-safety guidelines, requirements and procedures necessary to protect worker and public health from potential hazards related to the project activities. Chapter 5 will also be translated into Spanish prior to the commencement of site activities.

Chapter 6, CONTINGENCY PLAN, and Chapter 7, PROJECT PROFESSIONAL PERSONNEL, have 'been included to comply with the conditions of the Administrative Order.

2.2 SURFACE GEOPHYSICAL SURVEYING

2.2.1 INTRODUCTION

Electrical surface geophysical methods such as electromagnetic terrain conductivity (EM) and D.C. resistivity vertical electrical soundings (VES) may be used to obtain subsurface information on ground-water quality and lithology. The surveys may be used to correlate direct measurements obtained from soil borings and monitoring wells by increasing the number of data point locations without additional borings or wells.

The EM survey may be used to delineate the areal extent and location of clay strata and sand/gravel deposits which may effect ground-water flow. The VES method may also be helpful in defining lithologic changes which affect ground-water flow.

If boring logs and borehole geophysics (see Section 2.3) indicate substantial variation in the geology between wells, surface geophysics may be used on site. If surface geophysical surveys are considered appropriate for this project, the following equipment and procedures would be used.

2.3 SOIL-BORING ACTIVITIES 2

2.3.1 INTRODUCTION o NJ VO

As noted in the Work Plan for this investigation, there will be a num- *» ber of deep and shallow soil borings undertaken at the site. Four shallow

2-4

borings (PCSB-1 through 4) will be drilled in the vicinity of the lagoons, and deep soil borings will be drilled at the site of each of the 5 proposed monitor wells (PCMW-1 through 5).

Locations of the four shallow borings around the lagoon (PCSB-1 through 4) have been selected based on the following objectives: 1.) To obtain soil samples in close proximity to the original wastewater lagoons, and 2.) To determine the vertical distribution of any contaminants in the vicinity of the lagoon area.

Three deep soil borings at the site of monitor wells PCMW-1 , 2 and 3 will be advanced to bedrock. The remaining 2 deep soil borings at PCMV,'-4 and 5 will be advanced to depths consistent with the screen locations selected for the first three monitoring wells. Thus, field data, including on-site soil stratigraphy, borehole geophysics and soil testing for VCC's will be used to select the depth of soil borings at PCMW-4 and 5.

The locations of these soil borings are shown on Figure 2.3-1. All samples collected during the drilling and sampling operations will be field inspected by a hydrogeologist to establish the site lithology. Health and safety guidelines (Chapter 5) will be followed during drilling and testing operations.

Soil samples will be analyzed in the field with a portable Gas Chromatograph (GC) to gather data on the extent of any soil contamination with respect to volatile organics. These data will be used to establish a vertical profile of soil contamination. The contaminant profile developed from field GC data will be used, along with the soil stratigraphy to select 1.) the screened intervals of monitoring wells, 2.) soil samples that will be sent to ETC for complete chemical analysis, 3.) correlation of potential contaminant migration pathways, and 4.) samples for geotechnical testing. Complete chemical analysis on selected samples will be performed. Selected samples will be sent to Geotec, Inc. (Geotec) for geotechnical testing.

Following the completion of the deep borings, the borehole will be filled with a bentonite slurry (drilling mud) to maintain an open hole. Geophysical logs will be run in these boreholes to provide additional data to select the screened intervals of the monitor wells (Section 2.4). After geophysical logging, each borehole will be abandoned by filling with grout. Both borehole fluids will be collected and stored in drums prior to disposal according to local regulations.

2.3.3 PROCEDURE

1. Sampling will be performed by trained and experienced field technicians under the supervision of the on-site manager.

2. Soil samples will be retrieved with a split-spoon barrel at a minimum of 5 feet intervals. More frequent sampling may be indicated at lithologic or stratigraphic contacts.

3. The split-spoon barrel and spatula used to remove the samples from the split-spoon will be washed using soap and water and rinsed with distilled water between samples. The rinse water will be monitored periodically for volatile organics with the portable GC unit to prevent potential cross-contamination between samples. Wash and rinse water will be changed frequently.

4. Gloves will be worn whenever handling the split-spoon sampler. 5. Soil samples to be analyzed in the field with the GC will be col

lected in pre-cleaned l6-ounce wide-mouth jars. The glass jars will be sealed with teflon-lined lids.

6. Selected soil samples from each shallow boring will be sent to Environmental Testing and Certification (ETC) for analysis. These samples will be collected and sealed in pre-cleaned bottles provided by ETC. Samples to be sent to ETC will be selected based on field GC results and site stratigraphy.

7. During sampling, the task manager will record in the field log the number of blows required for each sample retrieval.

8. Open the split-spoon and discard the top portion of the sample which may represent disturbed soil.

9. Handle the sample carefully and quickly in order to avoid losing volatile components. 'fl

10. Split the sample longitudinally and place one half in the sample ^ jar for GC analysis. Cap tightly. Selected samples will be retained after GC analysis for geotechnical analysis. o

11. The other half of the sample will be sealed in pre-cleaned bottles for storage or shipment to ETC.

o

o NJ vo -J

2-7

12. Complete and affix a sample tag to the jar. Record the information in the sampling log book. Complete and sign a chain-of-custody form before relinquishing the sample to the field laboratory for immediate analysis.

13. The water levels encountered during soil sampling and drilling will be recorded.

14. Descriptions of soil samples will be recorded by the hydrogeologist as the samples are collected. A detailed lithologic log will be developed in the field during drilling.

15. Samples will be tested in a field laboratory for volatile organic compounds using EPA Method No, 8020 from Test Methods for Evaluating Solid Waste (SW-846).

16. Samples for testing by ETC will be sent by express courier. 17. Selected duplicate samples will be taken by placing each half of a

longitudinally split core in suitable container and filling out two sample tags indicating a duplicate sample.

18. Field blanks are taken by rinsing a pre-cleaned split-spoon sampler with distilled water and placing the water in a clean glass jar. Initially, field blanks will be taken and analyzed every six samples. As the sampling activities progress, the frequency of sampling will be determined from statistical analysis of previous data.

19. The deep borings will be filled with a bentonite slurry to maintain hole integrity for geophysical logging. This will be done by installing a tremie pipe near the bottom of the hole and pumping the slurry while removing augers. Care will be taken to maintain a positive head on the borehole fluid to prevent collapse of the hole.

20. Geophysical logs will be run in the boreholes. The logs run may include electrical resistivity, neutron, gamma-gamma, natural gamma, caliper and sonic.

21. After assuring that the logging is acceptable, the tremie pipe will be re-installed and the borehole abandoned by pumping grout into the hole. Grout will be pumped until return is noted at the land surface. The tremie pipe will be removed and any settling of grout will be filled from the top.

2.4 MONITORING WELL INSTALLATION

2.4.1 INTRODUCTION

' Monitoring wells will be installed at the site in Guayama, Puerto Rico. H

The purpose of these wells is to provide information regarding the hydro- ^ geologic setting, ground-water elevation and quality, to determine hydraulic conductivity of water-bearing zones, to define ground-water flow directions, o and to serve as observation wells during a pumping test to establish the *"" hydraulic characteristics of the aquifer system,

NJ VO 00

2-8

•

•

The locations of the monitoring wells shown on Figure 2,4-1 are selected based on several considerations. First, the general layout of the wells will provide information in various directions from the alledged contaminant source area (old wastewater lagoons) and the PRASA wells where contamination has been previously observed.

Based on the ground-water contours prepared by the USGS and shown on Figure 2.4-2, monitor well PCMW-1 is located upgradient of the lagoon and should help define the actual source of contamination. PCMW-2 is located between PRASA Well No. 3, where the highest contaminant levels have been reported by USEPA, and the old lagoons. PCMW-3 is located downgradient of both the old lagoons and the PRASA wells.

Monitoring Wells 4 and 5 are currently located to provide hydrogeologic data perpendicular to the reported direction of ground-water flow. Data from these wells can be used to determine the lateral extent of any contaminant plume that is detected.

The depth of the screened interval in the monitoring wells will be selected to provide communication with the soils having the highest potential of monitoring contaminants in the water-bearing strata. Screened intervals will be selected after evaluating field GC results, boring logs, borehole geophysics, and other data obtained from the soil borings located at the sites of PCMW-?, 2, and 3. Accordingly, monitoring wells PCMW-1, 2 and 3 will be installed in new boreholes drilled next to the first deep soil borings. Similarly, PCMW-4 and 5 will be installed in soil borings that are advanced to depths consistent with the screened zones in PCMW 1, 2 and 3.

Non-aqueous phase contaminants are not expected in the aquifer at this site due to the small quantities of potential contaminants used in plant operations, the clayey nature of subsoils and general site stratigraphy. However, if non-aqueous phase contaminants are encountered at the site this would be evident from the contaminant profile developed from onsite GC analyses of soil samples (Section 2.3).

2.4.3 PROCEDURE

1. Prior to commencement of drilling operations, site maps will be reviewed with regards to underground pipes and electrical cables. Written authorization for drilling from plant safety personnel will be obtained prior to drilling operations on AHP property.

2. The drill crew will be under the direct supervision of the on-site manager,

3. The drill rig will be steam-cleaned between monitor-well sites, 4. Six-inch (6") hollow stem augers will be used for drilling opera

tions. 5. Prior to installation, the two-inch diameter well casing and

screens will be kept in packing boxes; the steam-cleaned augers will be stored on plastic sheeting so as to minimize contamination possibilities.

6. The on-site manager will confirm the depth of the boring with a measuring tape once it has been determined that the final depth of the borehole has been reached.

7. The boreholes will be completed using clean augers and advanced to the bottom screen depth. The only sampling conducted in these boreholes would be for undisturbed samples (Shelby Tubes) for special geotechnical testing.

8. Well casings and screens will be two-inch diameter 316 stainless steel.

9. After boring to the selected final depth, and the integrity of the borehole has been confirmed, the casing and screen will be installed.

10. A silica sand will surround the screen and extend to approximately three feet above the screen.

11. Two foot bentonite seal will be placed above the sand. 12. The remainder of the annulus will be filled with a

cement/bentonite slurry to land surface using a tremie pipe system. A cement paid will be placed around each well that will direct surface water away from the casing.

13. A protective four-inch steel surface casing will be placed around each well casing. Locking caps will be installed on each well casing.

14. If, during completion of the monitoring well and prior to placement of the bentonite seal or before initial installation, the hole collapses, the hole will be redrilled with clean hollow stem augers to the original depth and installation will be completed through the augers.

16. When installing the monitoring pipe through the auger, special ^ care must be taken when placing the bentonite seal so as not to ^ create a plug inside the auger. Bentonite pellets must be dropped slowly and separately to ensure correct installation. o

2.5 HYDROLOGIC TESTING

2.5.1 INTRODUCTION

The development and testing of the monitor wells PCMW-1 through 5 will require several specific actions. Each of these activities is described below.

2.5.2 WELL DEVELOPMENT

Following monitor-well construction each well will be pumped, by air or suction, to clear the well and gravel pack of fine-grained materials. This activity allows for the assurance that the well screen is in good hydraulic connection with the aquifer and that water samples free of sediments will be obtained. The equipment and procedures for this activity are described below.

2.5.2.1 LIST OF PRIMARY EQUIPMENT

1 . Air compressor and associated hoses 2. Discharge pipe and/or hose 3. Clear glass jar (1 quart minimum) 4. 100-foot steel tape 5. Portable tank

2.5.2.2 PROCEDURE

1. Determine depth to water with tape. 2. Install pumping system. 3. Pump the well at highest rate practical. 4. Direct the discharge to an appropriate disposal/storage point. It

may be necessary to utilize a portable tank for discharge collection and transportation to the storage/disposal point,

5. Inspect the discharge water for turbidity intermittently by filling the glass jar and allowing the particulate matter, if any, to settle, "

6. Measure the water level intermittently to determine the amount of W drawdown caused by pumpage.

7. Terminate pumping when the discharge is no longer turbid and drawdowns are relatively stable.

8. Record the pumping rate, duration, and water-level drawdown and recovery.

2.5.3 DISPOSAL/STORAGE OF PURGE WATER

Because of the possibility of ground-water contamination at the site, all water removed from each well during development, or prior to sampling will be treated by the AHP wastewater plant. Before being added to the AHP waste stream the water will be field tested with the portable gas chromatograph to determine the compatibility with the AHP treatment process. Based on worst-case conditions (i.e., purge water saturated with each of the volatile organic compounds previously detected at the maximum volume of discharge) the AHP wastewater treatment plant can treat the purge water to 1 part per billion contaminant concentration in less than seven hours. Because worse-case conditions are not expected, disposal into the AHP system appears appropriate. If other conditions are noted appropriate disposal measures will be taken. The equipment and procedures for this activity are described below.


1. Water-storage containers 2. Tank truck 3. Portable GC 4. Approved storage/disposal containers

2.5.3.2 PROCEDURE

1. Collect the purge water in the appropriate temporary containers. A tank truck will be used when large volumes of water must be transported to the AHP treatment plant.

2. Obtain a composite sample of the purge water. 3. Run field GC analysis to determine compatibilities with AHP treat

ment process. 4. If compatible, transport to the AHP treatment system. 5. If incompatible, transfer to appropriate containers for

storage/disposal at an approved location,

2.5.4 PERMEABILITY TESTING

To aid in the evaluation of ground-water flow rates, monitor wells PCMW-1 through PCMW-5 will be tested to determine the permeability of the screened interval. This will be accomplished by introducing a slug of a known volume into the well to create a positive head on the aquifer at the well. The slug will be constructed of stainless steel and cleaned before ^ each test. Measurements of the decline in water levels following the Intro- co duction of the slug will be taken frequently until the water level in the well reaches pre-test levels. These measurements will be reported on forms § as shown on Figure 2,5-1, Following stabilization, the slug will be removed "-• and the well response again monitored,

The data from these tests will be field reduced and plotted to assure accurate data collection and to determine the need to retest the well. Analysis of the data will be by methods developed by Hvorslev (1959) or Ferris, et al. (1962).


1. Stainless-steel slug 2. Stainless-steel cable 3. Transducer unit or steel tape for monitoring water-level changes 4. Graph paper

2.5.4.2 Procedure

1. Measure depth to water from the designated measuring point. 2. If appropriate, install transducer into the well and record water

level above the transducer. 3. Drop slug into well and monitor water-level changes at frequent

intervals. 4. Record the water-level measurements and times on the

forms provided. 5. After stabilization, pull slug and again monitor water-level

changes. 6. Reduce and plot data for evaluation. 7. Calculate the permeability of the screened section of the aquifer.

2.5.5 WATER-LEVEL MEASUREMENTS

Water-level measurements taken during the investigation will utilize, to the extent possible, a steel tape marked in feet, tenths of a foot and hundredths of a foot. In those cases where tape measurements cannot be taken, an electronic tape similar to the QED Sample Pro Electronic Water Level Meter will be used. During permeability testing, a transducer unit may be , used.

Steel-tape measurements will be taken using the "hold/wet" method. In this method the tape is lowered into the well and the amount of tape "wet" is subtracted from the "hold" mark. An example of this method is shown on Figure 2.5-2,

All measurements will be recorded in the field on separate pages for each well. Any unusual measurements will be re-taken to confirm their accu- ,1 racy. When re-taping, a different "hold" mark will be used, n

2.6 GROUND-WATER SAMPLING

2.6.1 INTRODUCTION

Ground-water samples will be collected from the five PRASA production wells and one AHP well as soon as the SOP has been approved by the USEPA. These samples will be analyzed in the field with the portable GC unit for volatile organic compounds. These data will be compared to the I983 data and, should significant differences be noted, modifications to the RI may be necessary.

Samples will also be collected from the five monitor wells discussed in, the five PRASA wells and from one AHP production well for analysis by ETC. These analyses will establish the quality of the ground water ente.-ing and leaving the site. A second round of samples will also be collected from these same wells to determine what changes, if any, occur over a period of time.

2.6.3 PROCEDURE FOR MONITOR WELLS

1. Groundwater samples will be collected by field personnel under the supervision of the on-site QA officer.

2. Water samples to be analyzed in the field with a GC unit will be collected in pre-cleaned l6-ounce wide-mouth jars. Water saccles collected for shipment to ETC will be collected in sealed, precleaned bottles.

3. Use steam-cleaned stainless-steel bailers to collect samples. One bailer will be dedicated to each monitoring well. g

4. Before sampling, measure the static water level in the well with a ^ steel or electronic tape and record the measurement,

5. Calculate the volume of water in the well from the well depth, the o static water level, and the casing diameter. 2

6. Bail water from the monitoring wells until field measurements of temperature, pH and conductivity stabilize or at least 3 well vol- o umes are removed. The water removed from the well will be stored ^

2-19

in a portable storage tank prior to final disposal in the on-site waste-treatment facility,

7. Pour water down the side of the sample vial or jar to minimize turbulence during sample collection. For samples collected in vials, invert the vial once it is filled to ensure that there are no air bubbles. If air bubbles are found, another sample must be taken.

8. Fill containers, for field GC analysis (l6-ounce wide-ujouth jars) approximately half full with sample water. The glass jars will be sealed with teflon lined lids and screw caps.

9. Complete and affix a sample tag to each sample container. For samples that will be shipped to ETC, the tag will be protected with clear vinyl tape.

10. Check the sample number assigned to each bottle against the sample number on the chain-of-custody form.

11. Samples requiring preservation will have premeasured preservatives affixed to the bottles when they arrive on site. Samples to be shipped to ETC will be preserved as per instructions, supplied

- with the bottles. 12. Samples to be analyzed in the field will be taken to the field

laboratory for immediate analysis. A chain-of-custody form will be signed before the samples are relinquished.

13. Sample for ETC testing will be shipped by express courier.

2.6.4 PROCEDURE FOR WATER SAMPLING AT PRASA WELLS AND THE AHP WELL

1 . Prior to sampling, information will be compiled from PRASA or AHP regarding well size, pump type, yield, well reliability and electrical connections, and start-up procedures.

2. The wells will be sampled from a sampling point as close tc the pump as possible.

3. Discharged (purge) water from the PRASA wells will be stored in a portable storage tank prior to final disposal in the on-site treatment facility. Purge water from the AHP well will enter the AHP water-supply system.

4. At PRASA Well 3, a sample will be taken by bailer for field GC analysis prior to purging the well.

5. Prior to collection of the pumped sample, the pump will be run until field measurements of pH, temperature and conductivity stabilize or until 3 casing volumes of water have been removed.

6. When sampling from a water tap or water line, the packing should be tight and aerators must be removed to prevent a loss of vola- ' tile organics. BJ Water samples to be analyzed by the field GC will be collected in pre-cleaned l6-ounce wi and screw caps. These sample water and sealed.

pre-cleaned l6-ounce wide-mouth glass jars with teflon-lined lids o and screw caps. These jars will be filled about half full with M

8. Collect the samples for ETC analysis in a standard set of bottles. 9. When collecting samples for volatile organics analysis, pour water

down the side of the vial so as to minimize turbulence. Invert the vial when full and look for air bubbles. If bubbles are found, discard the sample and use another clean vial to collect a new sample.

10, Complete and affix a sample tag to each container. 11. Sign a chain-of-custody form before relinquishing the sample.

2.7 SURFACE-WATER SAMPLING

2.7.1 INTRODUCTION

Information shown on Figure 2.7-1, a topographic map of the area, indicates the presence of a surface water divide between the Guamani River and the AHP site. This divide prevents the movement of surface water to the river from the plant site. Likewise, ground-water information developed by the USGS and shown on Figure 2,4-1 indicate that in the area of the AHP plant, flow is to the southwest away from the river. For these reasons, surface-water sampling of the river is not anticipated as a part of the RI.

Should information be,developed during the site-specific field investigations that indicates an interaction between the Guamani Rivert and the AHP site does exist, the surface-water sampling program described below will be undertaken.


1. A standard set of sample bottles for each sample locations 2. l6-ounce wide-mouth jars 3. Protective gloves 4. A portable pH meter 5. Thermometer 6. A portable conductivity meter 7. Distilled water 8. A pre-cleaned "bail bottle" for each location

2.7.3 PROCEDURE

1, Samples collected for field analysis will be placed in l6-ounce wide-mouth jars. The jars will be sealed with teflon-lined lids ^ and screw caps. Samples collected for ETC analysis will be placed W in sealed, precleaned bottles. A standard set of bottles for each sample will be provided by ETC. g

2, Use protective gloves on the hand used to dip the bottles into the f-* surface-water body.

3. Submerge the bail bottle upside down just below the water surface. Invert the container slowly to allow it to fill with the surrounding water,

4. Remove the bail bottle and fill the sample containers that have preservatives with water from the bail bottle,

5. For sample collection in bottles and vials without preservative; collect the sample bottles directly from the surface-water body.

6. Invert the viali containing the samples for volatile organic analysis to ensure there are no air bubbles in the sample. If bubbles are found; discard that sample and collect another sample in a spare sample bottle.

7. Cap each sample container as soon as the sample is collected. 8. Collect an additional water sample in a clean l6-ounce glass jar

for immediate measurement of temperature, pH, and conductivity. 9. Sign a chain-of-custody form before relinquishing the samples. 10. Samples collected for ETC analysis will be shipped via express

courier. 11. Surface water samples will be analyzed for pH, temperature and

conductivity in the field.

2.8 SEDIMENT SAMPLING

2.8.1 INTRODUCTION

Section 2.7.1 of the SOP presents information describing why surface-water sampling of the Guamani River will not be undertaken as a part of the RI. This same rationale applies to sediment sampling of the river.

Should information be developed during the site-specific field investigations that indicates an interaction between the Guamani River and the AHP site does exist the sediment sampling program described below will be undertaken.

2.9 WATER-QUALITY ANALYSIS

2.9.1 INTRODUCTION

ETC will run laboratory analysis on ground-water samples collected from the 5 PRASA wells, the 5 monitoring wells and from one AHP well. If it is necessary to obtain water samples from the Guamani River, laboratory analysis of these samples will be run. On-site testing of water quality parameters including pH, conductivity, temperature and volatile organics will be performed on all samples. As a certified USEPA contract laboratory, ETC will utilize contract laboratory procedures during analytical activities.

The specific laboratory analyses to be run on the first round of water samples is listed in Appendix 4-A. These analyses include the constituents on the hazardous substances list as specified by the USEPA and included in the Administrative Order. This list includes the contaminants previously detected in the PRASA wells and their hazardous biodegradation products. Subsequent analysis of water samples may be run on a limited list of substances depending on the results of the first round.

Field analyses of all water samples will also be run with a portable GC unit.

2.11.1 INTRODUCTION

As stated in the Work Plan, there may be geotechnical testing of selected soil samples obtained during the soil-sampling activities (Section 2.3). The analyses will consist of grain-size distribution for all samples and permeability testing for selected clayey soils. These analyses may provide useful information on ground-water movement.

Selected soil samples obtained during the soil boring activities will be sent to Geotec, Inc. for geotechnical testing. Testing activities will follow ASTM specifications, as described below, for grain-size analyses and permeability testing. All samples to be analyzed by Geotec, Inc. will also be described and classified by Geotec, Inc. according to ASTM D-2488.

2.11.2 GRAIN-SIZE ANALYSIS

The samples to be analyzed for grain-size distribution will be collected according to the procedures detailed in 2.3, and sent to Geotec, Inc. At Geotec, the samples will be prepared according to ASTM D-421 , and sieved according to ASTM D-422. The results will be presented in a graphical format.

2.13 COMPUTER MODELING

2.13.1 INTRODUCTION

The USGS has developed an analog (electrical) model of the south coast of Puerto Rico, including the project area (Bennet, 1976). This model was used by the USGS in 1978 to investigate the water budget for the region as well as the potential for artificial recharge (Heisel, et al, 1978). Diaz (1971) developed an electrical analog model for the Guayama area and described its development and use in USGS OFR-57.

This analog model does not provide the ability for contaminant-plume simulation. Since a model developed for this investigation should have the capability of such simulation, a digital computer model would be required.

The use of ground-water flow modeling to simulate site conditions will be undertaken only if the data collected during the investigation indicate that such activities will provide a practical advantage to the RI and assist in evaluating remedial alternatives during the FS. Should conditions warrant the development of a model, it would be appropriate to first select a solute-transport analytical model consistent with available data. If the analytical model satisfactorily simulates contaminant-plume migration, additional modeling would not be needed. If, however, it is considered appropriate to develop a more sophisticated model, a digital model would be developed, so long as data are available to support it. The equipment and procedures for development and usage of the model(s) are shown below.

2.14 DATA VALIDATION, EVALUATION AND RI REPORT PREPARATION

Data generated throughout the RI will be validated and evaluated as it is developed. This will enable decisions to be made regarding subsequent RI tasks and allow early preparation of preliminary drafts of specific sections of the RI report. Validation methodology for field and laboratory analytical procedures are described in Chapter 4 of the SOP, SITE SPECIFIC QUALITY ASSURANCE/QUALITY CONTROL DOCUMENT.

The data validation and evaluation processes described in Chapter 4 and the associated appendices will result in reliable, accurate data upon which to base the RI report.

4.3 INTRODUCTION AND PROJECT DESCRIPTION

The Fibers Public Supply Well Field is located on the south side of Route 3 in Guayama, Puerto Rico. Figure 4.3-1 is a general index map of Puerto Rico showing the approximate location of the well field. Four of the five supply wells have been shut-down by the operator, the Puerto Rico Aqueducts and Sewer Authority (PRASA), as a result of reported contamination. Water samples collected from the wells in 1983 by the United States Environmental Protection Agency (USEPA) showed elevated levels of volatile organic compounds in the four wells that were shut-down. The wells have been included on the National Priorities List (NPL) of known and threatened releases of hazardous substances.

Studies performed by the United States Geological Survey (USGS) indicate that the Fibers Public Supply Wells are located downgradient of an industrial facility currently operated by Ayerst-Wyeth Pharmaceuticals, Inc., a subsidiary of American Home Products (AHP). This facility had been operated from 1966 to 1980 by subsidiaries of Phillips Petroleum Company and Chevron Chemical Company. During this period of time, wastewater from the facility was stored in two lagoons located on the north side of Route 3- A third adjacent lagoon to the west was utilized for storm water management. The USEPA believes the two wastewater lagoons are the source of the contamination at the PRASA wells. In 1985, the three lagoons were modified by AHP to provide a single storm water management facility.

Phillips and Chevron have voluntarily entered into an agreement with the USEPA to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the site. The general purposes of this RI/FS are: to confirm the presence, nature and extent of contamination; to identify the sources of contamination, to evaluate alternative and recommend a cost-effective remediation plan that will provide protection of the public health and welfare, and the environment.

Additional information pertaining to the requirements for conducting the RI/FS at the site is included in the USEPA Administrative Order, Index No. II - CERCLA 50301, and in a document entitled "Work Plan, Remedial Investigation/Feasibility Study, Fibers Public Supply .Well Field, Guayama, Puerto Rico", dated October 1985.

4.4 PROJECT ORGANIZATION

Equipment needed to carry out t h i s a c t i v i t y includes:

a. Gravity corer b. l6-ounce wide mouth jars c. Teflon-lined lids and screw caps d. Standard sets of bottles e. Stainless-steel lab spoon g. Protective gloves

The procedure for sampling sediments is shown below:

1. Sampling of the Guamani River sediments will be undertaken if verification of the ground-water flow directions indicate the potential for interaction with the surface-water system at the site.

2. Sediment samples will be placed in sealed, pre-cleaned 16 ounce wide mouth jars. Only one jar will be required for each sample.

3. A gravity corer will be used the collect the sediment samples. 4. A pre-cleaned corer will be attached to the required length of

sample line. The free end of the line will be secured to a fixed support to prevent accidental loss of the corer. The corer will be dropped freely to fall through the liquid, and retrieved with a smooth, continuous lifting motion.

5. Remove the sample from the corer and place into a sample bottle with a stainless-steel lab spoon.

6. Cap jar with teflon-lined lid and screw cap. 7. A sample .label will be completed and affixed to the jar and

covered with clear vinyl tape. 9. A chain-of-custody form will be signed before relinquishing the

sample to the laboratory for analysis. 10. Sediment samples will be analyzed for the chemicals shown in

Appendix 4-A.

4.7 SAMPLE CUSTODY

The objective of a chain-of-custody procedure is to document the history of each sample, and its handling. Chain-of-custody records are used to trace a sample from collection to final disposition after analysis has been performed. The on-site QA officer is responsible for ensuring that chain-of-custody procedures consistent with Section 1,3 of SW 846 are followed. These procedures include proper completion of sample identification and sample transfer records.

4,7.1 SAMPLE IDENTIFICATION

Sample identification is initiated by the sample collector. A stock of pre-cleaned glass jars with teflon-lined lids will be kept at the field laboratory under custody of the laboratory analyst. o

oo

4-16

M

O o

During sampling activities, the sample collector will affix a sample-identification label to every sample container prior to sampling. The sample identification label will be used to record the information shown on Figure 4.7-1.

The sample numbers assigned will be used on the chain-of-custody records to track each sample from collection to final analysis.

Numbers assigned to each sample will be recorded in the field office sample log as assigned. Information recorded on the sample label by the sample collector will also be recorded in the field office sample log.

4.7.2 SAMPLE TRANSFER PROCEDURES/CHAIN-OF-CUSTODY RECORDS

An individual chain-of-custody form is generated for each sample. The sample collector has the responsibility for the initial step in the chain-of-custody command. On returning a sample to the field laboratory, the collector will sign a chain-of-custody record as having relinquished the sample. The laboratory analyst will sign the form as receiving the sample and will enter the time and date of acceptance before proceeding with analysis.

The on-site QA officer is responsible for rechecking the sample tags against the chain-of-custody forms and entering the information from the sample-identification tags into the field office sample logs. A chain-of-custody form is shown on Figure 4.7-2. The on-site QA officer is also responsible for confirming the date of analysis and recording it in the sample logs.

The thermometer is pre-calibrated and will be calibrated on site by comparing readings with a second thermometer. The pH meter is calibrated with two premixed buffer solutions. One solution is for pH of 4.0 and another is for 7.0, Instrument readings will be calibrated prior to sampling using these standards. Similarly, a standard solution mixed at 700 micromhos per centimeter will be used to calibrate the conductivity meter readings prior to sampling. All calibration procedures and notes will be maintained in the field laboratory log book.

4.9 ANALYTICAL PROCEDURES

Detailed analytical procedures are presented in Appendix 4-B for the field gas chromatography analysis. Other field instruments are direct-readout instruments requiring the water sample to be in direct contact with the measuring probe.

Laboratory analysis by ETC will comply with EPA Contract Lab protocols shown in Appendix 4-A.

4.10 FIELD DATA ANALYSIS, VALIDATION AND REPORTING

4.10.1 DATA PRODUCTION

Analytical data are generated from two primary sources: field testir^ and laboratory testing. ETC testing utilizes several instruments (as indicated in Appendix 4-A) to obtain data. Field data is generated by a pK meter, thermometer, conductivity meter and gas chromatograph.

Analytical data generated by the field gas chromatograph includes the graphic output (chromatograms) identification of compounds, concentrations, retention times and comparisons to standards. The field gas chromatograph outputs will be checked manually for accuracy every 100 chromatograms.

Data production also includes internal records available for inspection during audits. These records include the following: laboratory notebooks, log book, worksheets, standards, records and associated quality-control data. A complete record of each sample's history will be available to document the progress from the field through laboratory analysis.

Steps and checks used to validate the precision and accuracy of the analytical work performed and to support its representativeness, comparability and completeness include:

4-20

• 1. Documentation of analytical and QC/QA methodology. 2. Description of the controls for interference contaminants (use of

reference blanks and check standards for method accuracy and precision) .

3. Description of the calibration of methods and instruments.

4.10.2 DATA VALIDATION

Validation of the analytical data will include review of the following:

1. Contaminants in lab blanks and field blanks. 2. Agreement between samples and duplicates.

Levels of contaminants in lab blanks must be low enough so as not to have an impact on the validity of the data. If contaminants are found in significant levels in one of the field blanks, the sample data will be reviewed to determine if comparable levels are found in other samples obtained that same day. The data will also be grouped to determine any effect the sampling team or equipment may have had in its overall validity.

The mean and standard deviation for each measured parameter for all samples will be calculated as an aid in identifying anomalous values. Spatial plots will be made to aid in detecting similarity in patterns.

4.10.3 DATA REDUCTION

Data reduction includes computation of summary statistics and their standard errors, confidence intervals, test of hypothesis relative to the parameters and model validation. Documentation of this process will be provided.

4.10.4 DATA REPORTING

Data will be reported in both tabular form and in spatial plots. The on-site QA officer will conduct a review of all completed sample data. A review of the data includes:

1. Verification that there are no contaminants in associated blanks 2. Comparison of samples and duplicates for matches in data results 3. Review of all data to make sure they are within acceptable quality

limits

4.11 FIELD PERFORMANCE AND SYSTEM AUDITS

4.11.1 FIELD SAMPLING SYSTEM AUDIT

The on-site coordinator will conduct a system audit prior to the first day of sampling. EPA may elect to observe this audit or conduct their own.

A system audit will include, but not be limited to the following:

1. Organization and Responsibility - Is the quality assurance structure operational?

2. Sample Collection - Are field personnel adequately trained? Are there any written procedures on sampling? Are they followed?

4.13 SPECIFIC PROCEDURES TO ASSESS DATA PRECISION, ACCURACY AND COMPLETENESS

Assessments of data precision, accuracy, and completeness will be made by ETC during the analysis of all samples sent to the lab. The methods utilized for making these assessments are included in Appendix 4-A.

Each measurement procedure, system, or instrument has predetermined limits to indicate when corrective action is required. ETC monitors their QC data to assure that it is within EPA Contract Lab limits.

Procedures designed to determine field sampling accuracy for laboratory analysis by ETC are to include one trip blank per shipment, one field blank per sample media and one duplicate sample. The blanks will permit the identification of compounds that may have been introduced during sampling or en-route to the lab.

Duplicate samples will be used in order to measure precision of field operations. This can be determined in terms of the Relative Standard Deviation.

RSD = s / X where: s = standard deviation X = Mean of the duplicate samples

4.14 CORRECTIVE ACTION AND FEEDBACK

Whenever a problem in sampling or analysis occurs, a corrective-action sequence is followed. This procedure is illustrated by the flow chart in Figure 4.14-1. To initiate action, a corrective-action request form is submitted to the on-site QA officer. An example of the corrective-action request form is reproduced in Figure 4.14-2. The on-site QA officer will be responsible for follow-up of corrective action requests. The QA officer will also be responsible for follow-up of corrective action requests.

LABORATORY DATA QUALITY OBJECTIVES

The purpose of the project is to col lect analytical data on the possible presence of l isted hazardous substances at the Fibers Public Supply Wells Site, Guayama, Puerto Rico. The target list for organics will be the current Hazardous Substances List as defined under U.S. EPA's Contract Lab Program (CLP) for 1986. Other parameters are included as outlined in Section 6 of this plan. The project samples will be processed according to the then current contract between ETC and the U.S. EPA CLP for organics analysis; and inorganics analyses according to ETC's Laboratory SOP.

It is the expressed intention of this OA plan that all requirements of the CLP protocol shall be complied with unless specifically modified by agreement among all concerned parties, in the event of any disagreement or ambiguity, the requirements of ETC's then-current CLP contract with EPA shall prevail. The tasks of this analytical project are l isted below;

Task 1 - Receive and prepare site samples

Task 2 - Extract ion and analysis for identity of specific organic compounds

Task 3 - Qualitative verif ication of the compounds identified in Task 2

Task 4 - Quantification of compounds verified in Task 3

Task 5 - QA/QC Procedures pertinent to the CLP shall be adhered to in this project

Task 6 - Reporting of all data in an ETC-selected format.

In order to accomplish the QA requirements of this project, ETC shall provide the following;

1. For each sample, execute the above listed tasks.

2. Provide all necessary information to sat isfy the Reoorting Requirements anc Deliverables Exhibit of the CLP protocol soecifically as selected by the ETC CLP Resource Manager.

3. Provide analytical equipment and tecnnical expertise for this project.

4. Designate key personnel meeting all requirements of the CLP contract to perform identical roles for this project.

5. Preserve all sample ex t rac ts after analysis m bot t les/v ia ls with Teflon-lined septa and maintained at 4 degrees 0 for a period of time specified by the CLP Resource Manager.

6. Adhere to standard ETC cham-of -custody procedures.

7. Schedule sample shipments to ETC's facil ity m Edison, New Jersey through the use of ETC's Project Management group.

GOOD LABORATORY PRACTICES

ETC maintains a Standard Operating Procedures (SOP) Manual governing the day- to -day laboratory activit ies and methodologies of choice for selected analyses, in addition, the current CLP contract specifies the SOP's level of ef for t required to document the processing of all samples within the CLP resource area. This ef for t should describe the quality assurance and quality control procedures used during analysis. These procedural resources are incorporated herein by reference and shall govern the execution of this project.

The Hazardous Substances List to be employed in this project is reproduced in Table 6-1 exact ly as given m the CLP Document currently in use by U.S. EPA. Although detection limits are strongly matrix dependent, every reasonable ef for t will be made to achieve the listed limit's. The additional parameters are presented in Table 6-2. Respective detection limits for water and soils will be on a best ef for t basis using, currently accepted EPA methodologies.

PREVENTATIVE MAINTENANCE PROCEDURES ANO SCHEDULE

ETC. being a highly computerized and instrument oriented laboratory , maintains Maintenance Contro ls with all instrument manufacturers with 24-hour, 7 days /week emergency call service. The frequency of scheduled preventat ive maintenance is outlined in the SOP.

In addition, ETC trains each analyst to respond to daily preventat ive maintenance needs. Criteria for this type of work is based on instrument performance. Failure of instruments to perform according to s ta ted methodologies and cri ter ia limits drives the need for daily maintenance.

ETC does use a log to record GC, GC/MS and H P L C maintenance records. This document includes not only our weekly maintenance, but also that performed by the manufacturer. This is conducted on a quality basis at the minimum.

SPECIFIC ROUTINE PROCEDURES TO ASSESS DATA PRECISION, ACCURACY AND CONDITIONS

Each compound used as a standard for cal ibrat ion or sample spiking is cert i f ied by ETC. Compound identity is verif ied by GC/MS and compound puri ty by GC/FID.

Recoveries are checked through the use of sur rogates in every sample and updated contro l limits are used as the standard to be achieved.

ETC will make every e f fo r t to meet or exceed the accuracy and precision data on the pr ior i ty pollutant organics prescribed in U.S. EPA Methods 624 and 625, or as necessary under CLP pro toco l .

Precision and accuracy requirements for other methods will be adhered to as defined in the method itself. If no precision.and accuracy requirements are st ipulated, ETC will establ ish these and maintain control limits.

The fol lowing formulas and protoco ls were used to calculate the precision and accuracy data compiled in each method of ETC's SOP and to subsequent ly establ ish OC limits.

Accuracy - the % agreement of a measurement wi th a known value.

Accuracy, % = (^^) 100 K

K = Known value of the spike X = Analytical result from the spiked sample T = Analytical result from the unspiked aliquot % Accuracy = % Recovery

Precision - degree of agreement among individual measurements under prescribed conditions.

R = Range A = Replicate Value 1 B = Replicate Value 2 N = 8 of duplicates

Standard Deviation - for Accuracy with Result ing Upper and Lower Control Limits

Validation Update - The above formulas and calculat ions were used to establish initial data validation procedures. All QC batches and appropriate data are kept by OA so that the validation limits may be updated on a regular basis.

Initial validation consisted of 20 data points; and updating occurs every 100 data points, or once a year, whichever is more frequent.

Section IS

Correct ive Action

Correct ive action can be taken at all operational levels and a lways involves OA personnel. After asessing the situation, appropriate s teps are always taken to cor rec t the problem. Samples af fected by the problem and whose resul ts are in doubt, are rerun after correct ion(s) are made. ETC recognizes the importance of cor rec t ive act ion in maintaining a high quality program. We believe that cor rect ive act ion can only result when data is suff iciently scrutinized. The Ouality Assurance plan described herein will permit the high level resul ts required for this pro ject .

Sample problems - Matr ix problems are normally handled at the analyst level. If surrogate recover ies are outside limits, the analyst may request a repeat analysis; both the lab manager and OA off icer are contacted. If severe inter ferences are present, the analyst may request additional sample clean-up or dilution upon approval of the lab manager.

QC batch problems - Initiation of cor rect ive act ion on a batch problem may occur at any level, but in all cases the lab manager and OC director are informed. The lab manager or QC director initiate all repeat batch ex t rac t ions and analyses. Repeated QA batch data are compared to previous results to confirm the problem has been resolved.

Systematic problems - Those problems of a procedural nature are handled by the lab manager and OA director. Final approval of any procedural changes and subsequent initiation of these changes are the responsibi l i ty of both the QA director and the Vice President of Operations.

Quality Assurance Reports to Management

The data from every sample analyzed is reviewed by the Quality Control department. This includes the actual sample data, blank, spiked blank, spiked sample and repl icate data. No sample data are repor ted without approval. If problems exist , they are discussed with the laboratory director and the director of the GC/MS group. These problems, if any, are resolved before results can be reported.

A final review of every report is made by the Project Manager or CLP Resource Manager.

QA report ing to management occurs at the fol lowing periods;

. Daily operat ions meeting to discuss possible QA problems and proposed solut ions among managers.

. Weekly meeting with upper management to discuss assessment of precision and accuracy to keep them informed of upcoming audits, cert i f icat ion programs, and past audit performances. Also discussed are systematic QA problems and possible solut ions.

APPENDIX 4-B

QUALITY ASSURANCE/QUALITY CONTROL PROGRAM FOR ON-SITE ANALYSES

M ro

o 4-B-1

4-B.1 SCOPE AND APPLICATION

The procedures presented in this appendix will be used to measure volatile organics on-site in a variety of media including air, water and soils. This method is recommended for use by, or under the direct supervision of analysts experienced in the operation of Gas Chromatography .(GC) and in the interpretation of chromatograms.

4-B.2 SUMMARY OF METHOD

This method provides chromatographic conditions for the detection of volatile organic compounds. Samples are collected using gas tight syringes and are introduced into the gas chromatograph by direct injection through an injection port.

Separation of compounds is achieved by using a chromatographic column selected for the compounds of interest. A temperature program is used in the gas chromatograph to optimize separation of the organic compounds. Detection is achieved by a Flame Ionization Detector (FID) or Photoionization Detector (PID).

If interferences are encountered, the method provides an optional second gas chromatographic column that may be helpful in resolving the coir-pounds of interest from the interferences.

4-B.3 INTERFERENCES

Before processing any samples, the analyst should demonstrate daily through the analysis of an organic-free water or injection of zero-grade nitrogen or air, that the entire system is interference free. Standard quality assurance practices should be used with this method. Field replicates are collected to validate the precision of the sampling technique. Laboratory replicates will be analyzed to validate the precision of the analysis. Where doubt exists over the identification of a peak on the gas chromatogram, known standards will be utilized to confirm results and to compare retention times of specific compounds in two different columns.

4-B.4 APPARATUS AND MATERIAL

4-B.4.1 GAS CHROMATOGRAPH

M

ro A Shimadzu Model 9A complete with a programmable gas chromatograph

Soil samples will be collected from split spoon samples taken during drilling. Samples will be split longitudinally and placed in 16 ounce glass jars as described in Section 2.3 of the (SOP). The jars will be sealed immediately in the field. After volatile contaminants have equilibrated with the headspace in the jar, a 1.0 ml sample of the headspace will be extracted for direct injection into the gas chromatograph.

Water samples from the monitoring wells, well development discharge, steam-cleaning area and split-spoon wash buckets will be obtained on a routine and as needed basis. Representative samples of water will be placed in l6-ounce jars and filled approximately half full. Jars will be sealed immediately with Teflon lined screw caps. After equilibrium conditions in the jar have been reached (15 to 60 minutes) a headspace sample will be taken with a 1.0 ml gas tight syringe. Analysis will be performed on-site by direct injection into the gas chromatograph.

4-B.7 PROCEDURES

4-B.7.1 GC OPERATING CONDITIONS

The recommended GC columns and operating conditions for the instrument are:

Column 1: Set nitrogen flow rate at 40 ml/min. Set column temperature at 45 degrees C. for 3 minutes, then program an 8 C/min. temperature rise to 220 degrees C. and hold for 10 minutes.

Column 2: Set nitrogen flow rate at 20 ml/min and initial temperature at 70 C. Program a 4 C/min temperature rise to 220 C. Hold final temperature for 5 minutes.

Column 3: Set nitrogen flow rate at 20 ml/min. Set column temperature at 45 C. for 5 minutes, then program a 8 C/min temperature rise to 120 C.and hold for 10 minutes.

4-B.7.2 CALIBRATION - EXTERNAL STANDARDIZATION METHOD

Calibration standards are prepared by adding a 1.0 ul concentration of a compound into a glass container sealed with teflon septas and allowing to completely volatilize at room temperature. A sample of the gas is withdrawn using a 1.0 ml gas tight syringe and injected into the gas chromatograph for analysis. The concentration of the vapor standard is determined from the trj specific gravity of the liquid injected and the volume of the glass container. These standards must be prepared fresh daily. ro

o o Analyze each calibration standard according to the procedure being used

and tabulate peak area responses against the concentration in the standard. The result can be used to prepare calibration curves for each compound. In o

00 00 CO

4-B-4

addition, if the ratio of responses to concentration is constant over the working range, linearity through the origin can be assumed and a calibration factor can be used instead of a calibration curve. The calibration concentration and respective peak areas will then be input into the recorder/data collection system so that subsequent sample concentrations will be calculated automatically.

The working calibration curve or calibration factor must be verified each working day by the measurement of one or more calibration standards.

4-B.7.3 CONCENTRATION CALCULATIONS

Ambient air concentrations will be made automatically in the recorder by comparison of the vapor standards to the peak area response of the injected air samples.

Soil samples are analyzed using the headspace method as described above. The concentration of the volatile components in the vapor space above the soil sample will be measured based on the external vapor standards as described in Section 7.2.

The concentration of a contaminant in a soil sample is the sum of the mass of contaminant in each phase (dissolved and vapor) divided by the mass of the soil sample. The following formulas summarize the calculation:

Cs = mass in (headspace + soil vapor + adsorbed with soil water) mass of soil

Cs = (Vc-Ms/ps)xCh+f(1-ds)xMs/psxCh+fxdsx(Ms/ps)xCh/K Ms

Cs = Chx( Vc-h(Ms/ps)x( fx( 1-dsx( 1-1/H) )-1)) Ms

where: Cs = Concentration is soil sample (mg/kg) Ch = Concentration in headspace vapor (mg/l) Vc = Volume of sample container (1) Ms = Mass of soil sample (kg) ps = Soil density (kg/1) f = Porosity

ds = Degree of Water Saturation H = Henry's Law Constant

The headspace vapor concentration and the weight of soil sample will be ^ measured directly in the field. The volume of the sample container is known and Henry's Law Constants are obtained from published values for each compo- o nent of interest. Soil moisture content, porosity and density are estimated 2 for each soil sample based on previous data or on representative samples taken in the field. o

CO 00

4-B-5

The amount of contaminant in a soil sample is calculated by summing the mass in the headspace, soil vapor space and in the aqueous phase adsorbed to the soil particles. Mass in the headspace is the headspace volume (total volume of container less soil volume) multiplied by the concentration. Soil volume is determined based on the mass of the soil divided by the soil density.

Soil vapor concentrations within the soil matrix will be the same concentration that is measured in the headspace when the headspace is analyzed at or near equilibrium. Therefore, the mass of contaminant in the soil vapor space is the volume of soil vapor (soil volume multiplied by the air-filled porosity) multiplied by the headspace concentration. Air-filled porosity within a sample can be estimated from the moisture content, total porosity and density of the soil.

The remaining mass of contaminant in the soil sample is assumed to be in equilibrium with the aqueous phase of the soil matrix which is also in equilibrium with the headspace concentration. Accordingly, the air/water partition coefficient (Henry's Law Constant) is used to calculate the concentration of each contaminant in the aqueous phase based on the vapor phase concentration in the headspace. The mass of a contaminant absorbed in the soil matrix is calculated based from the water saturation, soil density and mass of the soil sample.

The accuracy of the calculated concentration in soil can be affected by variations in temperature, soil density, degree of water saturation, and organic content of the soil. It is anticipated that variations in these parameters during the analysis at the site will not significantly affect the results due to the relative consistency of the analytical parameters at the site.

Calculations of volatile organic concentrations in water samples will be calculated based on the vapor concentration in the headspace, Henry's Law Constant and the weight of the water sample. The following formula is used:

Cw = (Cone. Air x Volume Air) -f- (Cone. Water x Volume water) Volume Water

Cw = (Ch x (Vc - Vw)) -t- (Ch/H x Vw) Vw

where: Ch = Concentration in headspace vapor (mg/l) Vc = Volume of sample container (1) H = Henry's Law Constant

Vw = Mass of water sample (kh) x water density (1.0 kg/1) M ro

4-B.8 QUALITY CONTROL

Before processing any samples, the analyst will demonstrate through the analysis of a distilled water blank or zero grade air sample that all glassware and reagents are interference-free. Each time a set of samples is extracted or there is a change in reagents, a method blank will be processed as a safeguard against chronic laboratory contamination. Additional field blanks will be drawn every 15 samples. Duplicate samples will be run every 10 samples.

The headspace method of analysis for soil samples is subject to saturation of the vapor space at very high concentrations (typically greater than 5000 ppm). If concentrations in the soil samples are encountered near this level, samples will be preserved for subsequent analysis by an alternative method.

The detection limit of vapor samples by this method is less than 0.5 ug/l. Accordingly, the method detection limit applied to soil samples is less than 1.2 ug/kg for compounds with Henry's Law Constants greater than 0.1 (which includes the standard compounds used here).

4-C.3.1 INTRODUCTION

The QA/QC methodologies described below provide a means of obtaining and reporting accurate hydrologic data. These activities require contact with potentially contaminated ground-water. Care must be given to assuring that the proper decontamination procedures are followed between wells.

Documentation of field activities is a significant portion of the site QA/QC and is equally important for these activities. In general, all data sheets will be dated and signed by the person collecting the data. The data sheets will be logged into the field log book for control purposes. Once entered in the log book, the original data sheets will not be carried into the field. Copies, however, will be used in the field for reference. Document-controls specific to each activity are described in the QA/QC methodology for that task.

4-C.6 COMPUTER MODELING

Computer modeling, if undertaken, will provide a method of simulating past or future ground-water conditions, flow patterns and contaminant plume location. The QA/QC procedures presented in this•section relate to model selection, data preparation, data entry, model calibration and verification, and report generation.

4-C.6.1 SUMMARY OF METHOD

The selection of the model (2.13.3.2) is the most significant element of this QA/QC section. In all cases, the choice of the model relates to the types of data available, the quantity, distribution and accuracy of the data and the modeling needs. The model selection must rely on published as well as project-generated data. The published data include water levels, water quality, regional estimates of hydrologic (aquifer) properties as well as estimates of irrigation and potable water withdrawals. Because of the minimum amount of reliable existing data in the specific area, a detailed ground-water flow model may be inappropriate. The model-selection process will review models to assure that the data needs and data availability are consistent. The procedures for this activity is described in Section 2.13 of the SOP. ni

5.0 HEALTH AND SAFETY PLAN

5.1 PROJECT DESCRIPTION

The Fibers Public Supply Well is located on the south side of Route 3 in Guayama, Puerto Rico. Figure 5.1-1 is a general index map of Puerto Rico showing the approximate location of the well field. Four of the five supply wells have been shut-down by the operator, the Puerto Rico Aqueducts and Sewer Authority (PRASA), as a result of reported contamination. Water samples collected from the wells in 1983 by the United States Environmental Protection Agency (USEPA) showed elevated levels of volatile organic compounds in the four wells that were shut-down. The wells have been included on the National Priorities List (NPL) of known and threatened releases of hazardous substances.

Studies performed by the United States Geological Survey (USGS) indicate that the Fibers Public Supply Wells are located downgradient of an industrial facility that was operated by Ayerst-Wyeth Pharmaceuticals, Inc., a subsidiary of American Home Products (AHP). This facility had been operated from 1966 to 1980 by subsidiaries of Phillips Petroleum Company and Chevron Chemical Company. During this period of time, wastewater from the facility was stored in two lagoons located on the north side of Route 3. A third adjacent lagoon to the west was utilized for storm water management. The USEPA believes the two wastewater lagoons are the source of the contamination at the PRASA wells. In I985, the three lagoons were modified by AKP to provide a single storm water management facility.

Phillips and Chevron have voluntarily entered into an agreement with the USEPA to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the site. The general purposes of this RI/FS are: to confirm the presence, nature and extent of contamination; to identify the sources of contamination, to evaluate alternative and recommend a cost-effective remediation plan that will provide protection of the public health and welfare, and the environment.

Additional information pertaining to the requirements for conducting the RI/FS at the site is included in the USEPA Administrative Order, Index No. II - CERCLA 50301, and in a document entitled "Work Plan, Remedial Investigation/Feasibility Study, Fibers Public Supply Well Field, Guayama, Puerto Rico," dated October 1985.

This Health and Safety Plan (HSP) is intended to provide a basic frame- ^ work for the safe conduct of the investigations at the Fibers Public Supply ^ Well Field, Guayama, Puerto Rico. The procedures contained in the HSP are based upon information presented in the above-referenced work plan and an o evaluation of site conditions by health and safety (H/S) personnel of both ^ Phillips and Chevron. These procedures provide a guide for all contractor and subcontractor employees who will be involved in the performance of the cP

investigation. While on AHP or other industrial properties, the safety guidelines of those companies will also apply.

The primary objective of the HSP is to establish, before site activities begin, work safety guidelines, requirements and procedures. The following information was prepared specifically for field sampling and collection operations of personnel assigned to this investigation. All employees are required to enforce and adhere to the established rules as specified in the HSP. To aid in accomplishing these objectives, the approved HSP will be translated into Spanish and made available to all personnel.

5.2 ORGANIZATION AND RESPONSIBILITIES

The organization and responsibilities for implementing safe site-investigation procedures, and specifically for the requirements contained in this manual, are described below.

The objective of this health and safety plan is to establish and ensure implementation of safety guidelines, procedures and practices, throughout all aspects of the project. Safety responsibilities must be incorporated into the site management roles to ensure the protection of all those involved. Additionally, all persons participating in such' investigations must be aware of the potential dangers and assume appropriate responsibilities to protect themselves and others. A daily log of all persons at the site will be maintained.

A well-defined organizational hierarchy is probably the single most important factor for instilling a strong safety ethic into operations during the project. Figure 5.2-1 is an organizational chart illustrating the hierarchy for the major project responsibilities.

exercise informed consent in working on site. 4. Report any accidents or hazardous conditions. 5. Have complete familiarity with their job requirements and the

health and safety procedures involved.

5.3 RISK ASSESSMENT AND PERSONAL PROTECTION

The presence of chloroethylene compounds (tetrachoroethylene and trichioroethylene) reported to be in and around the proposed sampling locations comprise the major concern for personal health. The low levels detected during water-quality sampling by the USEPA in 1983 were not of concern on a limited exposure basis. Nevertheless, the protection of personal exposure to these substances by inhalation, oral injection or dermal absorption is included in this plan. The health and safety officer is responsible for determining the level of personal-protection equipment required. When site conditions warrant, the health and safety officer will modify the level of protection to be utilized in the field.

An organic vapor analyzer (OVA) will be used to monitor ambient air quality at the site. During drilling operations, air quality will be monitored at each drilling location. Work operations which involve handling of potentially hazardous substances will include continuous contaminant monitoring using a direct-reading field OVA.

When deemed necessary or desirable by the health and safety officer, ^ area monitoring will be used in high hazard operations and in hazardous W zones on site. Area monitoring will be performed as plans and conditions dictate, and in accordance with the HSP and with the goal of accident and hazardous condition prevention in mind.

5.3.1 PERSONAL PROTECTIVE EQUIPMENT

At a minimum, protective headgear, eyewear and footwear will be worn at all times by personnel working around the drilling equipment. Should site conditions dictate, protective gloves and rubber boots may be required for those personnel handling contaminated soils or water at the site. Respirators for all personnel at the site will be available with both particulate and organic vapor protection cartridges. The health and safety officer will direct when the protective clothing and respirators will be utilized based on the conditions encountered at the site.

Only protective equipment deemed suitable by the health and safety officer for use on site will be worn. Any changes in protection levels shall be documented by the health and safety officer. Respirators will be cleaned dally and cartridges changed at least once per each eight hours of use. On~site field personnel should exercise informed judgment on protective gear requirements at active sites or at sites that have been repeatedly entered or occupied without apparent harm. In any case where doubt exists, the safe course of action must be taken.

5.3.2 SAFE WORK PRACTICES

In addition to the use of protective equipment, other procedures will be followed to miminize risk.

1. All consumptive activities including eating, drinking or smoking are prohibited during drilling, sampling and decontamination activities.

2. Portable emergency eye washes will be located on site during drilling, sampling and decontamination activities.

3. An adequate source of potable water to allow for emergency use will be available at the drilling sites.

4. Fire extinguishers will be on-site for use on equipment or small fires.

5. An adequately stocked first-aid kit will be on-site at all times during operational hours.

5.4 EMERGENCY CONTACTS

In the event of a safety or health emergency, appropriate corrective measures must immediately be taken to assist those who have been injured or exposed and to protect others from hazard. The on-site safety officer will be notified of the incident immediately. If necessary, first aid will be ^ rendered.

5.5 TRAINING

Training will consist of hazard-awareness training, use of protective clothing and equipment, and respirator use. Training will take place prior to commencement of work at the site. A log of personnel completing the training will be maintained and training certificates will be given to each individual completing the training. The certificate must be carried at all times during work activities on this project.

Hazard-awareness training will include a review of the suspected hazardous substances on-site, their physical and chemical properties, toxicity, health effects and symptoms of exposure. Emphasis will be placed on the practical reasons for and means of avoiding exposure to hazardous materials and other hazards.

Proper use of protective clothing and equipment will be demonstrated. Personnel involved in work on-site will be prepared to use air purifying respirators. Before being allowed to use a respirator, personnel will receive training in the use of respirators which will include:

6.0 CONTINGENCY PLAN

A contingency plan has been developed to address the possibility of fire or serious accident during the outlined field activities. During all field activities an adequately stocked first-aid kit and fire extinguishers, for use on equipment or small fires, will be on-site at all times during operational hours. Emergency contacts will be posted at the site and are included in the Health and Safety Plan.

Hazards from fire could be localized as in equipment fires or relatively large as in a cane-field fire. In either case, the primary goal is personal safety. If judgment indicates the possibility of extinguishing the fire or removal of equipment, extreme care should be taken. The appropriate agencies should be notified and field personnel should move to a place of safety.

Basic emergency first-aid procedures should be followed in the case of serious injuries caused by accidents. If needed, the injured party should be moved to a place of safety. Help should be called immediately if this can be accomplished without leaving the victim alone. An attempt should be made to stop or restrict any serious bleeding. The victim should be treated for the possibility of shock and should remain quiet (still).
