EXECUTIVE SUMMARY

On behalf of Lockheed Martin Corporation, AECOM Technical Services, Inc., has prepared this

report documenting the April, June, and September 2018 surface water monitoring at the

Lockheed Martin Corporation Middle River Complex in Middle River, Maryland. This report is

part of the long-term groundwater and surface water monitoring program at the Middle River

Complex. The objectives for the surface water monitoring program are to update surface water

analytical data, understand the nature and extent of contamination, evaluate contaminant trends

to supplement the ongoing remediation efforts, and assess off-site contaminant migration. The

surface water monitoring program for 2018 to 2020 includes three rounds of sampling and

chemical analyses of surface water in Dark Head Cove and Cow Pen Creek each year in April,

June, and September.

This report evaluates the April, June, and September 2018 surface water sampling analytical data

based on current and historical results. The April and June sampling rounds were previously

summarized and transmitted by Technical Memoranda to Lockheed Martin Corporation, the

Remediation Technical Operations contractor, and Maryland Department of the Environment.

During each sampling round, 18 field samples from 17 sampling locations at Cow Pen Creek and

Dark Head Cove were collected for chemical analysis. Surface water samples were sent to ALS

Environmental (in Middletown, Pennsylvania) to be chemically analyzed for volatile organic

compounds and 1,4-dioxane. Surface water samples for polychlorinated biphenyls were analyzed

by ALS Environmental in Rochester, New York. The analytical results were compared to

Maryland ambient water quality criteria for human health consumption of organisms (Code of

Maryland Regulations 26.08.02.03), United States Environmental Protection Agency Region III

Biological Technical Advisory Group freshwater screening levels (United States Environmental

Protection Agency, 2006), and Maryland Department of the Environment-approved site-specific

risk-based screening levels for swimming.

Findings from the April, June, and September 2018 surface water sampling are as follows:

• 1,4-dioxane – detected in four of fourteen primary surface water samples where it was analyzed for in 2018 (three samples from Cow Pen Creek and one sample from Dark Head Cove) with the highest concentration of 0.072 micrograms per liter (µg/L) at MRC-

June 2019 2018 Comprehensive Surface Water Report Page ES-2

22,000 µg/L. The concentrations are also below the Maryland Department of the Environment-approved site-specific risk-based swimming screening level of 30 µg/L.

• 1,2,4-trimethylbenzene – detected at an estimated concentration of 0.61 µg/L in MRC-SW8A-S in Dark Head Cove and adjacent to the southeastern Blocks E/F trichloroethene plume only during the June sampling event, below its ecological screening level of 33 µg/L.

• 2-butanone – detected in one Cow Pen Creek sample, MRC-SW2A at an estimated concentration of 1.9 µg/L only during the June sampling, below its ecological screening level of 14,000 µg/L.

• acetone – detected in a large majority of surface water sampling locations for all three sampling events in 2018, ranging from 3.1 to 21.5 µg/L, below its ecological screening level of 1500 µg/L.

• bromodichloromethane – detected at MRC-SW17A at an estimated concentration of 0.31 µg/L only during the June sampling, below its human health consumption screening level of 170 µg/L.

• bromomethane – detected at seven locations (June) and one location (September), all below its human health consumption screening level of 1,500 µg/L.

• carbon disulfide – detected at four locations (June only), below its ecological screening level of 0.92 µg/L.

• chloroform – detected in one sampling location in Cow Pen Creek, in MRC-SW17A at a concentration of 1.1 µg/L only during the June 2018 sampling, below its most conservative ecological screening level of 1.8 µg/L.

• cis-1,2-dichloroethene – detected in five surface water samples in Dark Head Cove: MRC-SW5A2-S, MRC-SW6A-S, MRC-SW13A-S, MRC-SW15A-S, and MRC-SW16A-S at concentrations ranging from 0.32 and 0.51 µg/L from the three 2018 sampling events, all below the most conservative Maryland Department of the Environment-approved site-specific risk-based screening level of 70 µg/L. Cis-1,2-dichlorethene is not used on-site but is a degradation product of trichloroethene, which was historically used on-site.

• naphthalene – detected at MRC-SW8A-S at an estimated concentration of 0.53 µg/L during the June sampling, below its ecological screening level of 1.1 µg/L.

• Polychlorinated biphenyls, as the dichlorobiphenyl homolog group – were detected at all 14 of the Dark Head Cove surface water sampling locations, ranging from 0.0019 to 0.0066 µg/L during the April 2018 sampling. In comparison, the detection of polychlorinated biphenyls, as the tertachlorobiphenyl group, was identified at just one location in 2017 (Tetra Tech Inc., 2017b). The April 2018 polychlorinated biphenyl concentrations are below site-specific risk-based swimming standards and below Maryland ambient water quality for organisms; however, they are above Maryland ambient water quality criteria (0.00064 µg/L) for human health consumption-of-organisms (Code of Maryland Regulations 26.08.02.03). Surface water sampling and analysis for

June 2019 2018 Comprehensive Surface Water Report Page ES-3

polychlorinated biphenyls was conducted only during the April 2018 sampling event and not during the June 2018 or September 2018 sampling events.

• trichloroethene – detected in six sampling locations in Dark Head Cove: MRC-SW6A-S, MRC-SW6B-S, MRC-SW8A-S, MRC-SW13A-S, MRC-SW15A-S, and MRC-SW16A-S at concentrations ranging from 0.59 to 2.5 µg/L from the three 2018 sampling events, all below screening levels. The two highest concentrations of trichloroethene observed during the June sampling (2.5 micrograms per liter in MRC-SW16A-S and 2.3 µg/L in MRC-SW15A-S) are where the southwestern portion of the southeastern Blocks E/F trichloroethene groundwater plume may discharge to Dark Head Cove.

To further evaluate the 2018 surface water polychlorinated biphenyl detections, Lockheed Martin

Corporation proposes two action items:

1. Perform a laboratory comparison study between the 2018 laboratory (ALS Environmental) and the previous laboratory (TestAmerica), by obtaining full data packages from both laboratories for the existing 2017 and 2018 analyses, and perform a thorough review of method detection limits, reporting limits, laboratory quality controls, and recoveries to identify any potential laboratory issues contributing to the detections.

2. Conduct an interim limited-scope surface water sampling event in Dark Head Cove. Laboratory split samples will be collected as a set of co-located field samples at eight of the Dark Head Cove locations, which will be analyzed by the two different laboratories (TestAmerica and ALS Environmental), prior to the April 2019 surface water sampling event to determine if procedures used by the different laboratories caused the variability between the 2017 and 2018 results. Laboratory split samples will be collected at a rate of 100% for polychlorinated biphenyl homolog analysis. The results of this study will be submitted to Maryland Department of the Environment once it is available.

SECTION 1 INTRODUCTION

On behalf of Lockheed Martin Corporation, AECOM Technical Services, Inc., has prepared the

following report for the April, June, and September 2018 surface water monitoring at the

Lockheed Martin Corporation Middle River Complex in Middle River, Maryland (see Figure 1).

This report details the analytical results from 17 surface water samples and one duplicate sample

collected along Dark Head Cove and Cow Pen Creek. Site contaminants at the Middle River

Complex could potentially be introduced to surface water through groundwater discharge or

through groundwater infiltration into storm drains, thereby discharging into surface water

through nearby outfalls.

Before 2017, surface water had been sampled annually. In 2017, the sampling frequency

increased to three times per year (April, June, and September) to assess whether volatile organic

compounds were reaching Dark Head Cove and Cow Pen Creek during implementation of the

groundwater remedy at concentrations exceeding site-specific risk-based swimming screening

levels. Additional sampling (as compared to previous surface water events) was conducted in

2017 to determine if polychlorinated biphenyls were in surface water subsequent to the sediment

removal actions and in-place treatment that Lockheed Martin Corporation performed in Dark

Head Cove between 2013 and 2017, and to determine if the Block G 1,4-dioxane groundwater

plume is potentially discharging to Cow Pen Creek (see Appendix A).

This technical memorandum is organized as follows:

• Section 1—Introduction: Presents objectives for the surface water monitoring program.

• Section 2—Site Background: Briefly describes site history and surface water sampling history.

• Section 3—Investigation Approach and Methodology: Presents the technical approach to surface water sampling and describes the field methodology employed.

• Section 4—Analytical Results: Discusses the analytical results for each analyte.

• Section 5 – Summary: Summarizes findings and conclusions.


• Section 6—References: Cites references used to compile this report.


SECTION 2 SITE BACKGROUND

The Middle River Complex, part of the Chesapeake Industrial Park, is located at 2323 Eastern

Boulevard in Middle River, Maryland. It is located approximately 11.5 miles northeast of

downtown Baltimore. It is composed of approximately 161 acres, including 12 main buildings,

an active industrial area and yard, perimeter parking lots, an athletic field, a vacant concrete lot, a

trailer and parts storage lot, and numerous grassy spaces along its perimeter. It is bounded by

Eastern Boulevard (Route 150) to the north, Martin State Airport to the east, Dark Head Cove to

the south, and Cow Pen Creek to the west. Figure 2 shows the Middle River Complex site layout.

LMC Properties, Inc., owns the Middle River Complex. Its primary activities at the Middle River

Complex include facility and building management and maintenance. The main site tenant, MRA

Systems, Inc., designs, manufactures, fabricates, tests, overhauls, repairs, and maintains

aeronautical structures, parts, and components for military and commercial applications.

Lockheed Martin Rotary and Mission Systems (a division of Lockheed Martin Corporation)

conducts engineering activities and fabricates, assembles, tests, and otherwise supports vertical-

launch systems.

2.1 MIDDLE RIVER COMPLEX HISTORY

In 1929, the Glenn L. Martin Company (a predecessor entity of Lockheed Martin Corporation)

acquired large parcels of undeveloped land in Middle River, Maryland, on which to manufacture

aircraft for the United States government and commercial clients. In the early 1960s, Glenn L.

Martin Company merged with American-Marietta Company to form Martin Marietta

Corporation. In 1975, the adjacent eastern airport area (currently Martin State Airport),

approximately 750 acres, was transferred to the State of Maryland. In the mid-1990s, Martin

Marietta Corporation merged with Lockheed Corporation to form Lockheed Martin Corporation.

Shortly after the merger, General Electric Company entities acquired most of Lockheed Martin

Corporation’s aeronautical business in Middle River and the General Electric subsidiary, MRA

Systems, Inc., began operations at the site.


2.2 MIDDLE RIVER COMPLEX CHARACTERISTICS

2.2.1 Physiography

The Middle River Complex is in the Western Shore of the Coastal Plain physiographic province,

which is generally characterized by low relief. The Middle River Complex’s topography slopes

gently, ranging from sea level to 32 feet above mean sea level (Cassell, 1977). The topography

declines from Eastern Boulevard to the southwest and south toward Cow Pen Creek and Dark

Head Cove.

2.2.2 Hydrology

The Middle River Complex is at the junction of Cow Pen Creek and Dark Head Cove. Both of

these surface water bodies discharge into Dark Head Creek, a tributary of Middle River, which is

a tributary of Chesapeake Bay. The Middle River Complex is approximately 3.24 miles

(17,100 feet) upstream of Chesapeake Bay. The Middle River Complex has no surface water

bodies on-site.

Surface water runoff discharges from the facility via storm drains, except for areas immediately

adjacent to Cow Pen Creek and Dark Head Cove. Lockheed Martin Corporation maintains a

National Pollutant Discharge Elimination System permit (state discharge permit

No. 00-DP-0298, National Pollutant Discharge Elimination System No. MD0002852), issued by

the Maryland Department of the Environment Industrial Discharge Permits Division, Water

Management Administration. The permit covers storm-water discharge from the entire property,

rather than from individual tenants.

2.2.3 Regional Hydrogeology

Sand and gravel zones in the unconsolidated surficial deposits at the Middle River Complex,

when present, may form an unconfined or water table aquifer system (Bennett and Meyer, 1952).

The water table at the Middle River Complex generally conforms to the land surface, with the

highest water levels in interior land areas and the lowest levels at approximately surface water

elevations along the shoreline. The Patuxent Formation is the most important water-bearing

formation in the Baltimore area. Industrial wells in the southeastern part of the area, specifically

Curtis Bay and Sparrows Point, yield 500-900 gallons per minute. In these industrialized areas,


the transmissivity and storage coefficient in confined portions of the aquifer average about

50,000 gallons per day per foot and 0.00026, respectively.

The Patapsco Formation is also an important water-bearing formation in industrialized

Baltimore, where it is separated by clay into a lower and an upper aquifer. Industrial wells

screened in the lower aquifer yield as much as 500–750 gallons per minute, with an estimated

transmissivity of 25,000 gallons per day per foot (Bennett and Meyer, 1952).

2.3 SURFACE WATER

Dark Head Cove and Cow Pen Creek receive groundwater discharge from the Middle River

Complex either directly or through groundwater infiltration into storm drains, thereby

discharging into surface water through nearby outfalls. Chemicals of concern found in Middle

River Complex groundwater (e.g., trichloroethene and 1,4-dioxane) have historically been

detected both in creek and cove samples. Sampling of surface water and sediment adjacent to the

Middle River Complex’s southern and western property boundaries began in March 2005 (Tetra

Tech, 2005).

Sampling in 2005 and from 2010-2017 was performed to: (1) characterize surface water and

sediment, (2) conduct a human health and ecological risk assessment, (3) aid in subsequent

design of the sediment and groundwater remedies, and (4) support storm-drain investigations

(Tetra Tech, 2017b). The current ongoing sampling program seeks to determine the extent to

which chemicals in groundwater and soil at the Middle River Complex are being transported to

surface water, and if constituents in sediments might be affecting surface water. The sampling

program (occurring each year in April, June, and September) is also designed to provide

analytical data during times of greatest recreational use of these surface water bodies.


SECTION 3 INVESTIGATION APPROACH AND METHODOLOGY

The overall objective in characterizing site surface water is to provide updated surface water

quality data. Surface water analytical data from Cow Pen Creek and Dark Head Cove will be

used to assess the nature and extent of contamination, including potential contaminant transport

from the Middle River Complex (MRC) into surface water. Before beginning fieldwork,

appropriate personnel from AECOM Technical Services, Inc., (AECOM) reviewed the site-

specific health and safety plan (HASP) and the respective “Safe Work” permits and emergency

response plan included in the HASP. AECOM conducted mandatory health and safety tailgate

meetings before each day’s fieldwork and twilight debrief meetings at the end of each day. The

AECOM site health and safety officer documented the topics covered and personnel in

attendance. All surface water sampling was conducted in accordance with the 2018–2020

Groundwater and Surface Water Monitoring Work Plan and its addenda (AECOM, 2017, 2018a,

2018b).

3.1 SURFACE WATER SAMPLING

The April, June, and September 2018 surface water sampling described herein provides

additional and updated surface water quality data for Dark Head Cove and Cow Pen Creek.

Specifically, current goals are to determine whether volatile organic compounds (VOCs),

polychlorinated biphenyls (PCBs), and/or 1,4-dioxane previously detected in groundwater and

soil may be reaching Dark Head Cove and Cow Pen Creek via groundwater seepage, infiltration,

or transport through nearby storm drains at concentrations greater than the established site-

specific risk-based swimming screening levels (Tetra Tech, 2017b). Concentrations of VOCs,

PCBs, and 1,4-dioxane in surface water were determined through laboratory analyses of the

collected samples.

All samples in Dark Head Cove and Cow Pen Creek were collected with dedicated, disposable

tubing, attached to a depth transducer that was part of the YSI water quality meter, which

measures the water quality parameters outlined in Section 4.4. The meter was lowered to one

foot below the water surface and marked by electrical tape on the cord at the one foot mark. The


appropriate length of tubing was cut (to ensure collection from one foot below the water surface)

and samples were collected via a peristaltic pump set at a purge rate of approximately

500 milliliters per minute. The one exception to this is MRC-SW17A, located in Cow Pen Creek.

MRC-SW17A was collected approximately three to six inches below the water surface (total

water column thickness) during each sampling event using either a dipper cup or peristaltic

pump.

3.1.1 Dark Head Cove

Fourteen surface water samples were collected each sampling round in Dark Head Cove at and

near Outfalls 005E, 005W, 006, 007, 008, and 009 which discharge to the cove (Figure 3). Two

samples were collected at Outfalls 006, 007, 008, and 009: one sample from 10-feet offshore

(“A” sample) and a second sample from 50-feet offshore (“B” sample). Three sampling locations

west of Outfall 008 (MRC-SW13A-S, MRC-SW15A-S, and MRC-SW16A-S) do not have an

associated “B” sample. These surface water samples were collected 10-feet offshore. Two outlets

are at Outfalls 005: 005E and 005W. One sample was collected at each outlet, 10 feet offshore,

recorded as the 5A1-S and 5A2-S samples during each round of sampling. A single sample was

collected 50 feet offshore, perpendicular to the bulkhead and halfway between the outlets, and

was recorded as the “5B-S” sample (Table 1).

3.1.2 Cow Pen Creek

Two samples (MRC-SW1A and MRC-SW2A) were collected along the centerline of the Cow

Pen Creek, with one sample collected upstream of the southwestern trichloroethene (TCE) plume

near the Block G swale outfall and one sample collected downstream of the southwestern TCE

plume during each sampling event. A third sample (MRC-SW17A) was collected near Outfall

003 and represents the farthest upgradient sample in Cow Pen Creek that can be collected within

the Lockheed Martin Property boundary. MRC-SW17A, was collected immediately downstream

of the Baltimore Gas and Electric property boundary during each sampling event.

3.1.3 Chemical Analyses

Surface water samples were analyzed at ALS Environmental (in Middletown, Pennsylvania) for

chemical analysis of VOCs and 1,4-dioxane. Surface water samples for PCBs were analyzed by

ALS Environmental in Rochester, New York. In addition to VOCs, Cow Pen Creek surface

water samples were analyzed for 1,4-dioxane, Dark Head Cove surface water samples were


analyzed for PCB homologs, and select samples were analyzed for 1,4-dioxane. Sampling

methods are described in the 2018-2020 Groundwater and Surface Water Monitoring Work Plan

and addenda (AECOM, 2017, 2018a, 2018b).

The current surface water sampling program is summarized in Table 1. Analytical testing for

PCBs is performed only in the April round of sampling for Dark Head Cove samples. Selected

surface water samples collected in 2018 were analyzed for 1,4-dioxane because it had been

detected in the 2017 groundwater samples in the southeastern TCE Blocks E/F groundwater

plume, and screening levels for 1,4-dioxane had since been revised lower.

One duplicate sample for each parameter (VOCs, 1,4-dioxane, and PCB homologs) was

collected during the April, June, and September 2018 surface water sampling events. One trip

blank sample per sampling event (i.e., one per cooler) was also collected for VOC analysis for

quality assurance/quality control purposes. Water quality parameters, including color,

temperature, pH, specific conductance, hardness, salinity, turbidity, dissolved oxygen, and

oxidation-reduction potential, were measured at all surface water sampling locations at the time

of sampling.

3.1.4 Staff Gauges and Tidal Stages

Both existing staff gauges in Dark Head Cove had been damaged or destroyed and were replaced

in June 2018. As a result, the Wilson Point Park direct-read staff gauge was used during the

April 2018 sampling. Tidal stages were recorded on April 16 and 17, 2018, before and after

sampling. The day before sampling began (April 15), approximately 0.34 inches of precipitation

was recorded during a heavy rain, and an additional 0.68 inches of rain was recorded during the

first day of sampling.

Tidal stage at the time of sample collection for the June and September events was recorded from

two staff gauges shown on Figure 3. One staff gauge is located in Dark Head Cove at the

confluence with the mouth of Cow Pen Creek (MRC-STAFF02) and the other is located in Dark

Head Cove in the vicinity of Outfall 009 (MRC-STAFF01). Tidal stages were recorded before

and after sampling during the April, June, and September surface water sampling. Tidal

information from the Bowley Bar Point station, southeast of Middle River, Maryland, was used

to track tidal stages during the three sampling events. All tidal information is documented on the

surface water sampling forms, in Appendix B.


3.2 MOBILE DATA-COLLECTION DOCUMENTATION

All site activities and observations, including an overall record of field activities, were recorded

on electronic field log sheets and submitted in daily field reports to the Remediation Technical

Operations (remediation oversite contractor for Lockheed Martin Corporation [Lockheed

Martin]). Completed chains-of-custody and matrix specific sampling log sheets were maintained.

Log sheets for each sample collected are presented in Appendix B.

AECOM used two Esri’s mobile applications, Survey123 and Collector for ArcGIS® (Esri, 2011)

during surface water data collection. They feature map and business logic that enhances a

technician’s ability to locate and record accurate data.

Once in the field, if the technician required location services, needed to reference a base map, or

needed to add or edit a location, Collector for ArcGIS® was used. The technician was also able to

review historical information about the location, make edits, and take photos with the

application, as required. New records were created within Survey123, leveraging form-based

business logic, including related reference tables, and if/then-style follow-up fields.

Upon sampling completion, the technician submitted the record from their mobile device, where

it was synchronized with AECOM’s Portal for ArcGIS®. The team could access data

immediately once it had synchronized. Data was downloaded from Portal for ArcGIS® and were

available to be used in any other geographic information system (GIS) or database management

system. Sampling locations were also surveyed using a handheld global positioning system

receiver in the Maryland State Plane North American Datum 1983.

3.3 EQUIPMENT DECONTAMINATION

No decontamination fluids other than distilled water were used for the surface water sampling.

Distilled water rinse was discharged directly into Dark Head Cove or Cow Pen Creek. Therefore,

collecting and disposing of rinse water generated during the sampling events was unnecessary.

3.4 WASTE MANAGEMENT

No investigation-derived waste was generated during this surface water sampling. Purge water

was returned to the surface water bodies after each sample was collected. General waste, e.g.,

gloves and tubing, was disposed of as general refuse.


3.5 DATA REVIEW

Laboratory data were entered into an internal sample database and evaluated against site-specific

risk-based swimming screening levels and applicable regulatory criteria. AECOM performed a

manual data review and data validation using the EQuIS™ Automated Validation Assistant tool.

This included completing a limited data review (evaluating data completeness, holding times,

laboratory and field blank contamination, laboratory batch quality control, field duplicate

precision, and detection limits) concurrent with the data evaluation review. The review is based

on the United States Environmental Protection Agency (USEPA) National Functional

Guidelines for Organic Superfund Methods Data Review (USEPA-540-R-2017-002, January

2017a) and USEPA National Functional Guidelines for Inorganic Superfund Methods Data

Review (USEPA 540-R-2017-001, January 2017b) for an Organic/Inorganic Level I

(https://www.epa.gov/quality/epa-region-3-data-validation) data review. Data were reviewed

based on the specifics of the analytical method used. The data-qualifying flags applied to the

surface water chemical results during data validation are identified in the Data Validation

Reports in Appendix C. The majority of the data is considered usable and meets the

completeness requirement outlined in the Quality Assurance Project Plan. Chain of Custody

forms are part of the Laboratory Analytical Reports presented in Appendix D.

3.5.1 Trip Blanks

Trip blanks are used to monitor contamination of VOCs from ambient sources present during

laboratory processing and field shipment. These blanks are prepared by the laboratory and travel

with the bottleware shipment from the laboratory to the field, and then back to the laboratory

with the collected field samples. Field samples are considered to be associated with specific trip

blank results only if those samples were shipped in the same cooler as the trip blank. The blanks

remain sealed from the moment that they are filled in the laboratory until they are extracted upon

returning to the laboratory.

Trip blank TB-062518 collected during the June 2018 event detected acetone at 8.5 micrograms

per liter (µg/L). Detected results that were within five times the concentration in the trip blank

were qualified “B” and should be considered usable as estimated values. The positive associated

field sample results that were within five times the blank concentrations were qualified “B” and

should be considered usable as estimated values.


3.5.2 Method Blanks

Method blanks are used to monitor contamination of target analytes during the analytical

procedure. They are prepared by the laboratory for each analysis batch and are analyzed

alongside field samples in that batch and undergo the same treatment as the field samples in the

batch during extraction and analysis. Field samples are considered to be associated with method

blanks only if they were prepared and analyzed in the same quality control batch. A detection in

the method blank indicates that contamination is present in the laboratory and was introduced to

the blank in the same spatial and temporal setting as the field samples. If positive field sample

results are associated with method blank detections and are within five times the concentration in

the blank they are qualified “B”. In instances where positive results in other blanks (trip blanks,

field blanks, or equipment blanks) are qualified “B” due to method blank detections, the

concentrations in those blanks would be considered false positives. Therefore, the field sample

results associated with the other blanks would not be qualified “B” unless the method blanks in

their respective analytical batches displayed detections.

Method blanks 2770157 and 2770696, associated with the June sampling event, displayed

detections for carbon disulfide at 0.32 µg/L and bromomethane at 0.54 µg/L, respectively. The

positive associated field sample results that were within five times the blank concentrations were

qualified “B” and should be considered usable as estimated values.

Additionally, method blank 2766541 displayed a detection for 1,4-dioxane at 0.029 µg/L

associated with the June sampling event. The positive associated field sample results that were

with five times the blank concentration were qualified “B” and should be considered usable as

estimated values. If these detections were treated as true positives, no concentration of the

associated “B” flagged field sample results would exceed the site-specific risk-based swimming

screening levels.

3.5.3 Data Usability

During the June data review, the MS/MSD performed on parent sample MRC-SW17A for 2-

chloroethyl vinyl ether displayed percent recoveries less than the lower quality control limits,

and less than the rejection limit of 20%. The associated parent sample results were non-detect

and were qualified R, m. These anomalies are considered major and the “R” qualified field

sample results should be considered unusable. All other data was considered usable and met the


completeness requirement outlined in the Quality Assurance Project Plan section of the work

plan and its addenda (AECOM, 2017). The overall completeness of the data reviewed was

acceptable at 99%. Except for those flagged “R”, all data are considered usable as qualified, for

their intended purpose based on the data reviewed.

Acetone was detected in a majority of surface water sampling locations for all three sampling

events, ranging from 3.1 to 21.5 µg/L. Acetone is a common laboratory contaminant used in

decontaminating equipment. Many acetone sample detections have an associated “B” flag that

was added during data validation, indicating that the detections are possibly due to sample

carryover from the laboratory and might be false-positives. The BTAG ecological screening

level for acetone is 1,500 µg/L.

3.6 ENERGY, ENVIRONMENT, SAFETY AND HEALTH-GIS DATABASE

AECOM uploaded the surface water sampling locations and validated data into the Lockheed

Martin Energy, Environment, Safety and Health (EESH)-GIS database for the April, June, and

September surface water sampling events.

3.7 SUSTAINABILITY APPROACH

AECOM incorporated Green and Sustainable Remediation practices into the surface water

monitoring program at the MRC to advance Lockheed Martin’s Corporate EESH key objectives

to protect, enhance, optimize and simplify, and to highlight the added values that sustainable

practices bring.

AECOM implemented sustainable approaches in all aspects of work wherever practical and with

prior approval from Lockheed Martin and the Remediation Technical Operations contractor

(remediation oversite contractor for Lockheed Martin Corporation). For the MRC monitoring

program, AECOM implemented paper-free electronic data collection across all aspects of the

surface water sampling program. This data collection approach and the use of rechargeable

batteries for field instruments reduced total waste and provided resource efficiency. The

utilization of local field staff, carpooling, and the use of locally sourced materials wherever

possible contributed to reduced overall mobile emissions.


SECTION 4 ANALYTICAL RESULTS

Validated analytical data from the April, June, and September 2018 surface water sampling were

evaluated with respect to ecological and human health screening-level criteria, including:

• Maryland ambient water quality criteria for human health consumption of organisms(Code of Maryland Regulations [COMAR] 26.08.02.03)

• United States Environmental Protection Agency (USEPA) Region III BiologicalTechnical Advisory Group (BTAG) freshwater screening levels (USEPA, 2006)

• Site-specific risk-based swimming screening levels. Site-specific swimming screeninglevels were developed in 2017 for trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), and 1,4-dioxane for Dark Head Cove and Cow Pen Creek, Middle River Complex(MRC). These risk-based swimming screening values (Table 2) were approved by theMaryland Department of the Environment (MDE) in 2017.

Site contaminants in groundwater at the MRC could potentially be introduced to surface water

through groundwater discharge or through groundwater infiltration into storm drains, thereby

discharging to surface water through nearby outfalls.

The analytical data suggest that a method of transporting groundwater contaminants of concern

to surface water exists, via either of the two pathways described above. Table 2 presents the

detected analytes from each sampling location for each sampling event and compares them to the

screening levels identified above. Table 2 summarizes detections in 2018. The distribution of

detections is shown in Figure 4 and a statistical summary table is provided in Table 4.

As shown in Table 2, the detected volatile organic compound (VOC) and 1,4-dioxane

concentrations for both Cow Pen Creek and Dark Head Cove are well below their various

respective screening criteria. To improve readability throughout Section 4, the leading “MRC”

prefix before each sample name has been dropped, i.e., MRC-SW17A will henceforth be referred

to as SW17A.


4.1 VOLATILE ORGANIC COMPOUNDS

Eleven VOCs were detected in surface water: 1,2,4-trimethylbenzene, 2-butanone, acetone,

bromodichloromethane, bromomethane, carbon disulfide, chloroform, chloromethane,

cis-1,2-DCE, naphthalene, and TCE. These detections are discussed below.

4.1.1 Trichloroethene

Trichloroethene, the primary VOC of concern associated with groundwater at the MRC, was

detected in six sampling locations in Dark Head Cove: SW6A-S, SW6B-S, SW8A-S, SW13A-S,

SW15A-S, and SW16A-S at concentrations ranging from 0.59 to 2.5 micrograms per liter (µg/L)

in 2018. The two highest concentrations of TCE were observed in the June sampling event

(2.5 µg/L in SW16A-S and 2.3 µg/L in SW15A-S) where a portion of the southeastern

groundwater plume in Blocks E/F discharges to Dark Head Cove. All other TCE detected

concentrations were lower, ranging from 0.59 to 1.6 µg/L.

Neither USEPA nor MDE have established acute or chronic freshwater criteria for TCE;

however, both entities have established a human health consumption-of-aquatic-organism

criterion of 300 µg/L for TCE when adjusted for the MDE risk level of 1×10-05 (i.e., a one in

100,000 risk). The BTAG ecological screening level for TCE is 21 µg/L. The maximum TCE

concentration (2.5 µg/L) detected in this investigation is more than eight times below the most

conservative regulatory screening level of 21 µg/L, and more than 12 times below the MDE-

approved risk-based swimming screening level of 30 µg/L for evaluating exposure risks to

swimmers (Table 2).

4.1.2 cis-1,2-Dichloroethene

cis-1,2-Dichloroethene (cis-1,2-DCE), a breakdown product of TCE, was detected in five surface

water samples in Dark Head Cove: SW5A2-S, SW6A-S, SW13A-S, SW15A-S, and SW16A-S at

concentrations ranging from 0.32 to 0.51 µg/L, in 2018. There are no established USEPA

Region III or MDE acute or chronic freshwater criteria protective of aquatic life or human health

consumption-of-aquatic-organism criteria for cis-1,2-DCE. The BTAG ecological screening

level for cis-1,2-DCE is 590 µg/L. The maximum cis-1,2-DCE concentration (0.51 J µg/L)

detected in the 2018 sampling is more than 100 times below the most conservative screening

criteria of the MDE-approved site-specific risk-based swimming screening level of 70 µg/L for

evaluating exposure risks to swimmers (Table 2).


4.1.3 Additional Volatile Organic Compounds

During the June sampling event, a single detection of 1,2,4-trimethylbenzene was present at an

estimated concentration of 0.61 µg/L in SW8A-S in Dark Head Cove and adjacent to the

southeastern Blocks E/F TCE plume. In addition, SW8A-S had the only detection of naphthalene

at an estimated concentration of 0.53 µg/L. Chloromethane was detected at one location in Dark

Head Cove downgradient of the Blocks E/F southwestern chlorobenzene plume: SW5B-S, at an

estimated concentration of 0.35 µg/L.

Also, during the June 2018 surface water sampling event, chloroform was detected in one

sampling location in Cow Pen Creek, in SW17A at a concentration of 1.1 µg/L. In addition,

SW17A had the only detection of bromodichloromethane at an estimated concentration of

0.31 µg/L. 2-Butanone was detected in one Cow Pen Creek sample, SW2A at an estimated

concentration of 1.9 µg/L.

Acetone was detected in a majority of surface water sampling locations for all three sampling

events, ranging from 3.1 to 21.5 µg/L. The BTAG ecological screening level for acetone is

1,500 µg/L.

Additional VOCs, bromomethane and carbon disulfide, were detected in some Cow Pen Creek

samples and Dark Head Cove samples at concentrations ranging from 0.45 to 0.66 µg/L and 0.26

to 0.58 µg/L, respectively. However, all of these detections were qualified as “B” over the course

of data validation due to detections of target analytes in the associated trip blanks and laboratory

method blanks. All bromomethane and carbon disulfide detection results are below all ecological

and human health screening criteria.

4.2 1,4-DIOXANE

As shown in Figure 4, 1,4-dioxane was detected in all three surface water samples from Cow Pen

Creek (SW1A, SW2A, and SW17A) and one sample (SW8B-S) in Dark Head Cove with the

highest concentration of 0.072 µg/L from SW17A from the three sampling events. All detected

sample results are less than the reporting limits and are considered estimated concentrations.

Additionally, many 1,4-dioxane sample detections have an associated “B” flag that was added

during data validation, indicating that the detections are from blank contamination possibly due

to sample carryover from the laboratory. These concentrations are many orders of magnitude


lower when compared to the USEPA ecological screening level of 22,000 µg/L. The

concentrations are also below the MDE-approved site-specific risk-based swimming screening

level of 30 µg/L.

4.3 POLYCHLORINATED BIPHENYLS

Polychlorinated biphenyls, specifically the total dichlorobiphenyl homolog (the only PCB

detected), were detected in all 14 surface-water samples collected in Dark Head Cove in

April 2018. Concentrations range from a low of 0.0019 µg/L at SW13A to a high of 0.0066 µg/L

at SW7A-S. In 2014-2015, dredging in Dark Head Cove removed PCB-impacted sediment

around Outfall 005, and the remaining cove sediment dredging was completed in March 2017

(Tetra Tech, 2017b). PCBs are not chemicals of concern in southwestern groundwater and

therefore were not analyzed for in Cow Pen Creek surface water samples. Polychlorinated

biphenyls have been detected sporadically in Dark Head Cove samples.

Surface water location SW7A-S, which had the highest PCB concentration during the April 2018

sampling, had not been previously sampled; therefore, historical comparison data are not

available. Tetrachlorobiphenyl, the only PCB homolog detected in 2017 Dark Head Cove surface

water samples, was detected in only one sample (SW5A2S) at a concentration of 0.014 µg/L.

This sample was collected 10 feet from Outfall 005 in September 2017. In 2018, SW5A-S had a

concentration of 0.0033 µg/L.

Sediment with the highest concentrations of PCBs was removed from Dark Head Cove near

Outfall 005 during the sediment-removal action in 2014–2015, followed by a second removal of

sediment with lower concentrations in the cove in 2016-2017. Sediment with the lowest

concentrations is undergoing remediation via in situ application of a carbon amendment that

binds the PCBs, decreasing their bioavailability, and thereby removing them from the food chain

(Tetra Tech, 2017).

Note that during the April 2018 groundwater sampling, a field blank prepared by a field chemist

had a detection of 0.0090 µg/L for total dichlorobiphenyls. This blank also displayed detections

for total monochlorobiphenyls and total trichlorobiphenyls at 0.0045 and 0.0055 µg/L,

respectively. The blank was collected by opening the certified laboratory-grade deionized-blank-

water in field conditions, and pouring it directly into the laboratory-provided bottle ware. This


blank result was not applied to the surface-water-sample data validation, because it was collected

on land in Block E, one week before the surface water sampling.

Although the concentrations detected are significantly less than previously reported, all 14

samples collected exceed the human health consumption-of-organism’s screening-level criterion

of 0.00064 µg/L set in place by the COMAR 26.08.02.03 for total PCBs. No screening level is

associated solely with the dichlorobiphenyl homolog group. All total PCB concentrations

reported from the April 2018 sampling event are total dichlorobiphenyl homolog. PCB analytical

detections are not associated with high turbidity, and therefore possibly represent surface water

detections.

4.4 WATER QUALITY PARAMETERS

Water quality parameters were collected in the field during the April, June, and September 2018

sampling events. Water quality parameter data are presented in Table 3. Field parameters were

measured at a depth of approximately one foot below the water surface, prior to sample

collection, with the exception of field sample SW17A, which was collected directly from the

surface using a dipper or peristaltic tubing.

The slightly basic pH values for all three sampling events, ranging between 7.14 and 9.12, are

consistent with natural surface water in this region. Turbidity was consistent in most samples,

with the highest turbidity reported from SW17A within Cow Pen Creek at 32.1 nephelometric

turbidity units (NTU) during the April 2018 sampling. Overall, higher turbidity was observed

during the April sampling event that occurred after the rain event as described in Section 3.1.4.

However, most turbidity levels were reported below 10 NTU, with a mean turbidity of 6.7 NTU

between all 2018 sampling events. Dissolved oxygen (DO) levels, ranging from 6.49 to 10.32

milligrams per liter (mg/L), were reported during the 2018 sampling events, and are typical

values for a healthy estuarine environment. One exception to this is SW8A-S, which had a

reported DO value of 0.61 mg/L during the June 2018 sampling. However, this sample had

reported DO values of 9.26 mg/L and 8.80 mg/L during the April and September sampling

events, respectively. Therefore, the DO value of 0.61 mg/L during the June 2018 sampling event

may have been due to the DO probe malfunctioning during sampling and may not be indicative

of the actual DO concentration at SW8A-S. Additionally, all oxidation-reduction potential (ORP)

values are positive, ranging from 111.6 to 234 millivolts, which is consistent with surface water


containing oxygen. Positive ORP values are representative of an environment conducive to

oxidation, which aid in more effective bacterial break down of contaminants, which can lead to a

healthier body of water.


SECTION 5 SUMMARY

AECOM Technical Services, Inc., collected surface water samples during the April, June, and

September 2018 surface water sampling events from 17 locations throughout Cow Pen Creek

and Dark Head Cove on behalf of Lockheed Martin Corporation. The samples were collected,

sent to ALS Environmental Laboratories, and chemically analyzed for volatile organic

compounds, 1,4-dioxane, and polychlorinated biphenyls. These analyses were carried out to

determine if these constituents are in surface water and, if so, to assess whether there are

indications of their originating from stormwater outfalls, sediments, or groundwater plumes at

the Middle River Complex.

Trichloroethene was detected in six samples in Dark Head Cove and adjacent to the southeastern

Blocks E/F trichloroethene plume: SW6A-S, SW6B-S, SW8A-S, SW13A-S, SW15A-S, and

SW16A-S at concentrations ranging from 0.59 to 2.5 micrograms per liter (µg/L) from the three

2018 sampling events. The trichloroethene detection in surface water is possibly due to

groundwater to surface water discharge of the nearby trichloroethene-impacted groundwater

plume, originating in Block E and discharging through Block F. These trichloroethene

concentrations are below the United States Environmental Protection Agency screening level

value of 21micrograms per liter, well below the human health consumption of organism’s level

of 300 micrograms per liter per the Code of Maryland Regulations, and below the Maryland

Department of Environment-approved risk-based swimming screening level of 30 micrograms

per liter.

cis-1,2-dichloroethene, a breakdown product of trichloroethene, was detected in five surface

water samples in Dark Head Cove: SW5A2-S, SW6A-S, SW13A-S, SW15A-S, and SW16A-S at

concentrations ranging from 0.32 and 0.51 micrograms per liter from the three 2018 sampling

events. The maximum cis-1,2-dichloroethene concentration (0.51 J micrograms per liter)

detected during the June sampling is more than 100 times below the most conservative screening

criteria of the Maryland Department of the Environment-approved site-specific risk-based

swimming screening level of 70 micrograms per liter for evaluating exposure risks to swimmers.

June 2019 2018 Comprehensive Surface Water Report Page 5-2

All additional volatile organic compounds detected: 1,2,4-trimethylbenzene, 2-butanone, acetone,

bromodichloromethane, bromomethane, carbon disulfide, chloroform, and naphthalene were

below their respective ecological and/or human health screening criteria.

1,4-Dioxane was detected in all three surface water samples from Cow Pen Creek and one sample

(SW8B-S) from Dark Head Cove with the highest estimated concentration of 0.072 micrograms

per liter at SW17A from the three sampling events. These concentrations are many orders of

magnitude lower than the United States Environmental Protection Agency ecological screening

level of 22,000 micrograms per liter. The concentrations are also below the Maryland Department

of the Environment-approved site-specific risk-based swimming screening level of 30 micrograms

per liter.

Polychlorinated biphenyls homologs, specifically total dichlorobiphenyls, were detected in all 14

surface water samples that were analyzed for these constituents. Surface water sampling and

analysis for polychlorinated biphenyls was conducted only during the April 2018 sampling event

and not during the June 2018 or September 2018 sampling events. Concentrations range from

0.0019 µg/L in sample SW13A to 0.0066 micrograms per liter in sample SW7A, both collected in

Dark Head Cove. Although the concentrations detected are significantly less than in previously

reported years, all 14 samples collected exceed the human health screening level of

0.00064 micrograms per liter set in place by the Code of Maryland Regulation for total

polychlorinated biphenyls based on consumption of organisms. A fish consumption advisory is

currently in effect for Middle River, recommending consumption of no more than six meals of

blue crab per month for example, due to polychlorinated biphenyl contamination in the area.

Since high turbidity was not measured in the 2018 sampling event, polychlorinated biphenyls

analytical detections were not associated with high turbidity, and therefore possibly represent

dissolved surface water detections. A field blank was not collected or analyzed in the

polychlorinated biphenyl sampling event but polychlorinated biphenyls were also detected in a

field blank collected during the April 2018 site groundwater sampling, one week prior to the

surface water sampling event.

To further evaluate the 2018 surface water polychlorinated biphenyls detections, Lockheed Martin

Corporation proposes two action items:


thorough review of method detection limits, reporting limits, laboratory quality controls, and recoveries to identify any potential laboratory issues contributing to the detections.

2. Conduct an interim limited-scope surface water sampling event in Dark Head Cove.Laboratory split samples will be collected as a set of co-located field samples at eight ofthe Dark Head Cove locations, which will be analyzed by the two different laboratories(TestAmerica and ALS Environmental), in February 2019, prior to the April 2019 surfacewater sampling event to determine if procedures used by the different laboratories causedthe variability between the 2017 and 2018 results. Laboratory split samples will becollected at a rate of 100% for polychlorinated biphenyl homolog analysis. The results ofthis study will be submitted to Maryland Department of the Environment once it isavailable.

The 2019 groundwater and surface water sampling programs will also be modified to include the

comparison study and additional Quality Assurance measures upon agreement with Maryland

Department of the Environment. In addition, AECOM Technical Services, Inc. plans to revise

the 2018-2020 Groundwater and Surface Water Monitoring Work Plan and its addenda

(AECOM, 2017, 2018a, 2018b) to include a minimum of 48 hours of wait time prior to a

scheduled surface water sampling event if there is a precipitation event (greater than 0.1 inches)

to ensure site-representative sample data-quality and avoid chemicals of concern dilution

influenced by rain events.

I. ExecutiveSummary

Data validation was performed on 100% of the groundwater and surface water field investigative samples collected from April 4th, 2018 through April 30th, 2018 at the Lockheed Martin Middle River Complex located in Middle River, Maryland. The validation was performed to a United States Environmental Protection Agency (USEPA) Region III Inorganic Level I and Organic Level I based on the specifics of the analytical methods referenced and qualified according to the USEPA Contract Laboratory Program (CLP) National Functional Guidelines for Organic/Inorganic (January 2017) Superfund Data Review, with the exception of blank detections which were qualified according to the USEPA Region III modifications to the National Functional Guidelines defining the use of the “B” flag.

The review was assisted through the use of an electronic data management tool that compiles batch-level quality control (QC) data submitted with the laboratory deliverables and identifies anomalies for verification and qualification by the data reviewer. This information is provided in the form of a structured workbook that includes field sample analytical results, QC sample results, batch associations, and QC criteria. Prior to validation, the quality assurance procedures applied to this process include reviewing the output for data completeness based on laboratory deliverables and chain of custody reports, verification of QC criteria based on the aforementioned data validation guidelines and project-specific Quality Assurance Project Plan (QAPP), as well as strict control of data management permissions. The resulting data validation workbooks were evaluated and validated using the AECOM automated validation assistant (AVA) tool. The specific data elements that were reviewed include:

Holding times and sample preservation Blanks (Method, Trip, Field, and Equipment) Matrix spike (MS) and/or matrix spike duplicate (MSD) results Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) results Surrogate spike results Field duplicates Laboratory duplicates Sensitivity

Data validation qualifiers were applied to results where a QC nonconformance required qualification per USEPA guidance. All QC anomalies were assessed for their impact on data quality in regards to precision, accuracy, representativeness, completeness, comparability, and sensitivity (PARCCS) as discussed in II: PARCCS Data Quality. A detailed list of the QC non-conformances can be found in III: Data Validation Findings. The associated field sample results that required qualification are listed in IV: Qualified Field Sample Results

II. PARCCSDataQuality

Precision

Precision is the degree of agreement among repeated measurements of the same characteristic on the same sample or on separate samples collected as close as possible in time and place. Field sampling precision is measured with the field duplicate relative percent differences; laboratory precision is measured with laboratory duplicate relative percent differences and/or laboratory control spike and matrix spike duplicate relative percent differences.

During the review, several matrix spike pairs displayed relative percent differences greater than the quality control limits. However, all associated field sample results were either non-detect or previously qualified due to matrix spike percent recovery anomalies; no data qualifying action was taken.

A limited number of field duplicate pairs displayed relative percent differences greater than the quality control limit of 35%. The positive associated field sample results and field duplicate results were qualified J,fd. These anomalies are considered minor and the qualified results should be considered usable as estimated values.

Accuracy

Accuracy is a measure of confidence in a measurement. The smaller the difference between the measurement of a parameter and its "true" or expected value, the more accurate the measurement. Accuracy in the field was monitored through the use of negative controls such as trip blanks, field blanks, and equipment blanks, along with adherence to the standard operating procedures and sampling plans. Analytical accuracy was assessed through the measurement of percent recoveries in the laboratory control spike pairs (LCS/LCSD) and the matrix spike pairs (MS/MSD).

Several method blanks, trip blanks, equipment blanks, and field blanks displayed detections greater than the method detection limit. Per the USEPA Region III guidelines on the qualification of blank detections, associated field sample results that displayed concentrations within five times of the blank detection were qualified “B”. The qualified field sample results should be considered usable as estimated values.

During the review, several MS/MSD displayed percent recoveries outside the quality control limits. The field sample results associated with positive biases were non-detect and did not require data qualifying action. The positive field sample results associated with negative biases were qualified J-,m. Non-detect results associated with percent recoveries less than the lower control limit, but greater than 20%, were qualified UJ,m. All qualified data should be considered usable as estimated values.

Several LCS/LCSD displayed percent recoveries outside the quality control limits. The field sample results associated with positive biases were non-detect and did not require data qualifying

action. The field sample results associated with negative biases were non-detect and were qualified UJ,l. These anomalies are considered minor since all percent recoveries less than the lower QC limits were greater than 10%. The qualified field sample results should be considered usable.

Representativeness

Representativeness qualitatively expresses the degree to which data accurately reflect site conditions. Factors that affect the representativeness of analytical data include appropriate sample population definitions, proper sample collection and preservation techniques, analytical holding times, use of standard analytical methods, and determination of matrix or analyte interferences.

A limited number of analyses and/or extractions were performed outside of the technical holding time but did not exceed twice the holding time (at which point non-detect sample results would have been rejected). These anomalies were considered minor, and the associated non-detect field sample results were qualified UJ,h while positive results were qualified J,h. These anomalies are considered minor and the qualified field sample results should be considered usable as estimated values.

Comparability

Comparability is the extent to which data from one study can be compared directly to either past data from the current project or data from another study. Using standardized sampling and analytical methods, units of reporting, and site selection procedures helps ensure comparability. Standard field sampling methods and current CLP analytical methods by an accredited laboratory were used in this investigation.

Completeness

Completeness is a measure of the amount of valid data obtained from a measurement system compared to the amount of data expected under normal conditions. It is expected that laboratories will provide data meeting system quality control acceptance criteria for all samples tested. Project completeness is determined by evaluating the planned versus actual quantities of usable data. A total of 151 investigative field samples were validated, including 133 groundwater samples and 18 surface water samples. Additionally 14 field/equipment blanks and 2 investigation derived waste (IDW) samples were validated. Due to rejected data points associated with major anomalies, the overall data completeness was less than 100% at 99%.

Sensitivity

Sensitivity reflects the ability of the analytical method to detect analytes of interest below the level of concern. This goal is achieved by identifying the level of concern, choosing a method with appropriate method detection limits, and ensuring that the laboratory analyzes calibration

standards at or below the level of concern. The laboratory was able to achieve the lowest reporting limits based on the analytical methods employed and the variety of matrices encountered. Any analytes detected below the reporting limit and above the method detection limit were reported and qualified “J” as estimated values by the laboratory. The only field sample that displayed non-detect results at an elevated dilution factor (greater than 10 times) was MRC-MW27A, analyzed for Nitrite Nitrogen at a dilution factor of 25. This field sample result did not require qualification by the data reviewer and should be considered usable as reported.

Overall Impact on Data Usability

The bulk of the data was considered usable and met the completeness requirement outlined in the QAPP. During the course of the data validation, several minor anomalies were noted which is to be anticipated based on statistical predictability of standard analytical procedures. Several field sample results were qualified due to these minor anomalies. No major anomalies were identified over the course of data validation; therefore no field sample results were qualified as rejected. All data are considered usable, as qualified, for their intended purpose based on the data reviewed.

I. Executive Summary Data validation was performed on 100% of the surface water field investigative samples collected on April 25th, 2018 and April 26th, 2018 at the Lockheed Martin Middle River Complex located in Middle River, Maryland. The validation was performed to a United States Environmental Protection Agency (USEPA) Region III Inorganic and Organic Level I based on the specifics of the analytical methods referenced and qualified according to the USEPA Contract Laboratory Program (CLP) National Functional Guidelines for Organic/Inorganic (January 2017) Superfund Data Review, with the exception of blank detections which were qualified according to the USEPA Region III modifications to the National Functional Guidelines defining the use of the “B” flag.

The review was assisted through the use of an electronic data management tool that compiles batch-level quality control (QC) data submitted with the laboratory deliverables and identifies anomalies for verification and qualification by the data reviewer. This information is provided in the form of a structured workbook that includes field sample analytical results, QC sample results, batch associations, and QC criteria. Prior to validation, the quality assurance procedures applied to this process include reviewing the output for data completeness based on laboratory deliverables and chain of custody reports, verification of QC criteria based on the aforementioned data validation guidelines and project-specific Quality Assurance Project Plan (QAPP), as well as strict control of data management permissions. The resulting data validation workbooks were evaluated and validated using the AECOM Automated Validation Assistant (AVA) tool. The specific data elements that were reviewed include:

• Holding times and sample preservation • Blanks (Method, Trip, Field, and Equipment) • Matrix spike (MS) and/or matrix spike duplicate (MSD) results • Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) results • Surrogate spike results • Field duplicates • Laboratory duplicates • Sensitivity

Data validation qualifiers were applied to results where a QC nonconformance required qualification per USEPA guidance. All QC anomalies were assessed for their impact on data quality in regards to precision, accuracy, representativeness, completeness, comparability, and sensitivity (PARCCS) as discussed in II: PARCCS Data Quality. A detailed list of the QC non-conformances can be found in III: Data Validation Findings. The associated field sample results that required qualification are listed in IV: Qualified Field Sample Results

II. PARCCS Data Quality

Precision Precision is the degree of agreement among repeated measurements of the same characteristic on the same sample or on separate samples collected as close as possible in time and place. Field sampling precision is measured with the field duplicate relative percent differences; laboratory precision is measured with laboratory duplicate relative percent differences and/or laboratory control spike and matrix spike duplicate relative percent differences. All quality control criteria impacting precision were met for the data reviewed.

Accuracy Accuracy is a measure of confidence in a measurement. The smaller the difference between the measurement of a parameter and its "true" or expected value, the more accurate the measurement. Accuracy in the field was monitored through the use of negative controls such as trip blanks, field blanks, and equipment blanks, along with adherence to the standard operating procedures and sampling plans. Analytical accuracy was assessed through the measurement of percent recoveries in the surrogate spikes, laboratory control spike pairs (LCS/LCSD) and the matrix spike pairs (MS/MSD).

Several method blanks, trip blanks, equipment blanks, and field blanks displayed detections greater than the method detection limit. Per the USEPA Region III guidelines on the qualification of blank detections, associated field sample results that displayed concentrations within five times of the blank detection were qualified “B”. The qualified field sample results should be considered usable as estimated values.

During the review, the MS/MSD performed on parent sample MRC-SW17A displayed percent recoveries less than the lower quality control limits, and less than the rejection limit of 20%. The associated parent sample results were non-detect and were qualified R,m. These anomalies are considered major and the “R” qualified field sample results should be considered unusable.

Several LCS/LCSD displayed percent recoveries greater than the quality control limits. The positive associated field sample results were qualified J,l. These anomalies are considered minor and the qualified field sample results should be considered usable as estimated values.

The surrogate spikes performed on samples MRC-SW13A, MRC-SW6B, and TB-062518 displayed percent recoveries greater than the upper QC limits for 4-bromoflurobenzene. The positive associated field sample results were qualified J+,s unless previously qualified due to a LCS percent recovery anomaly. These surrogate anomalies are considered minor and the qualified field sample results should be considered usable as estimated values with a positive bias.

Representativeness Representativeness qualitatively expresses the degree to which data accurately reflect site conditions. Factors that affect the representativeness of analytical data include appropriate sample population definitions, proper sample collection and preservation techniques, analytical holding times, use of standard analytical methods, and determination of matrix or analyte interferences. All quality control criteria impacting representativeness were met for the data reviewed.

Comparability Comparability is the extent to which data from one study can be compared directly to either past data from the current project or data from another study. Using standardized sampling and analytical methods, units of reporting, and site selection procedures helps ensure comparability. Standard field sampling methods and current CLP analytical methods by an accredited laboratory were used in this investigation.

Completeness Completeness is a measure of the amount of valid data obtained from a measurement system compared to the amount of data expected under normal conditions. It is expected that laboratories will provide data meeting system quality control acceptance criteria for all samples tested. Project completeness is determined by evaluating the planned versus actual quantities of usable data. A total of 19 samples were validated, including 17 surface water samples and two trip blanks. Due to rejected data points associated with major anomalies, the overall data completeness was less than 100% at 99%.

Sensitivity Sensitivity reflects the ability of the analytical method to detect analytes of interest below the level of concern. This goal is achieved by identifying the level of concern, choosing a method with appropriate method detection limits, and ensuring that the laboratory analyzes calibration standards at or below the level of concern. The laboratory was able to achieve the lowest reporting limits based on the analytical methods employed and the variety of matrices encountered. No field sample results were reported from dilutions. Any analytes detected below the reporting limit and above the method detection limit were reported and qualified “J” as estimated values by the laboratory.

Overall Impact on Data Usability The bulk of the data was considered usable and met the completeness requirement outlined in the QAPP. During the course of the data validation, several minor anomalies were noted which is to be anticipated based on statistical predictability of standard analytical procedures. Several field sample results were qualified due to these minor anomalies. A limited number of major

anomalies were identified over the course of data validation with minimal impact on overall data quality. The overall completeness of the data reviewed was acceptable at 99%. Except for those flagged “R”, all data are considered usable as qualified, for their intended purpose based on the data reviewed.

Appendix A Data Validation Qualifiers and Reason Codes

Data Qualifying Codes

Two types of data qualifying codes or flags are applied in the course of the data review. The data validation flags indicate data that are not usable for decision-making, more than normally biased and/or variable, or not representative of field conditions. These codes and their definitions are presented below in the hierarchy stipulated in the USEPA Contract Laboratory Program National Functional Guidelines for Organic (August 2014) Data Review and the USEPA Region III Guidelines for Organic (September 1994) for blank qualifications only.

Data Validation Flags

Flag Interpretation

R The sample results are unusable due to the quality of the data generated because certain criteria were not met. The analyte may or may not be present in the sample.

B The analyte was analyzed for, but not detected at a level greater than or equal to the level of the adjusted Detection Limit (DL) for sample and method.

J+ Reported value may not be accurate or precise, but the result may be biased high.

J- Reported value may not be accurate or precise, but the result may be biased low.

J

The analyte was positively identified and the associated numerical value is the approximate concentration of the analyte in the sample (due either to the quality of the data generated because certain quality control criteria were not met, or the concentration of the analyte was below the Limit of Detection (LOD).

NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated numerical value represents its approximate concentration.

UJ The analyte was not detected at a level greater than or equal to the adjusted DL. However, the reported adjusted DL is approximate and may be inaccurate or imprecise.

C This qualifier applies to pesticide and Aroclor results when the identification has been confirmed by gas Chromatograph/Mass Spectrometer (GC/MS)

X This qualifier applies to pesticide and Aroclor results when GC/MS analysis was attempted but was unsuccessful.

The other type of code used by AECOM is a “Reason Code”. The reason code indicates the type of quality control failure that led to the application of the data validation flag.

I. Executive SummaryAECOM performed data validation on 100% of the surface water field investigative samplescollected on September 21st, 2018 at the Lockheed Martin Middle River Complex located inMiddle River, Maryland. The validation was performed to a United States EnvironmentalProtection Agency (USEPA) Region III Inorganic Level I and Organic Level I based on thespecifics of the analytical methods referenced and qualified according to the USEPA ContractLaboratory Program (CLP) National Functional Guidelines for Organic/Inorganic (January 2017)Superfund Data Review, with the exception of blank detections which were qualified accordingto the USEPA Region III modifications to the National Functional Guidelines defining the use ofthe “B” flag.

The review was assisted through the use of an electronic data management tool that compilesbatch-level quality control (QC) data submitted with the laboratory deliverables and identifiesanomalies for verification and qualification by the data reviewer. This information is provided inthe form of a structured workbook that includes field sample analytical results, QC sampleresults, batch associations, and QC criteria. Prior to validation, the quality assurance proceduresapplied to the process itself consist of reviewing the output for data completeness based onlaboratory deliverables and chain of custody reports; verification of QC criteria based on theaforementioned data validation guidelines and project-specific Quality Assurance Project Plan(QAPP); and strict control of data management permissions. The resulting data validationworkbooks were evaluated and validated using the AECOM automated validation assistant(AVA) tool. The specific data elements that were reviewed include:

· Holding times and sample preservation· Blanks (Method, Trip, Field, and Equipment)· Matrix spike (MS) and/or matrix spike duplicate (MSD) results· Laboratory control sample (LCS)/laboratory control sample duplicate (LCSD) results· Surrogate spike results· Field duplicates· Laboratory duplicates· Sensitivity

Data validation qualifiers were applied to results where a QC nonconformance requiredqualification per USEPA guidance. All QC anomalies were assessed for their impact on dataquality in regards to precision, accuracy, representativeness, completeness, comparability, andsensitivity (PARCCS) as discussed in II: PARCCS Data Quality. A detailed list of the QCnon-conformances can be found in III: Data Validation Findings. The associated field sampleresults that required qualification are listed in IV: Qualified Field Sample Results.

II. PARCCS Data Quality

PrecisionPrecision is the degree of agreement among repeated measurements of the same characteristic onthe same sample or on separate samples collected as close as possible in time and place. Fieldsampling precision is measured using the field duplicate relative percent differences; laboratoryprecision is measured using laboratory duplicate relative percent differences and/or laboratorycontrol spike and matrix spike duplicate relative percent differences. All quality control criteriaimpacting precision were met for the data reviewed.

AccuracyAccuracy is a measure of confidence in a measurement. The smaller the difference between themeasurement of a parameter and its "true" or expected value, the more accurate themeasurement. Accuracy in the field was monitored through the use of negative controls such astrip blanks, field blanks, and equipment blanks, along with adherence to the standard operatingprocedures and sampling plans. Analytical accuracy was assessed through the measurement ofpercent recoveries in the surrogate spikes, laboratory control spike pairs (LCS/LCSD) and thematrix spike pairs (MS/MSD).

One trip blank and three method blanks were assessed for their effect on data usability. Onemethod blank displayed detections greater than the method detection limit for chloroform andhexachloro-1,3-butadiene. The associated field sample results were non-detect and did notrequire qualification by the reviewer.

Several LCS/LCSD displayed percent recoveries outside the quality control limits. The fieldsample results associated with positive biases were non-detect and did not require qualificationby the data reviewer. The field sample results associated with negative biases were non-detectand were qualified UJ,l. These anomalies are considered minor and the qualified field sampleresults should be considered usable as estimated values with a negative bias.

The MS/MSD performed on parent samples MRC-SW2A and MRC-SW5B-S displayed percentrecoveries outside the quality control limits for several analytes. The parent sample resultsassociated with positive biases were non-detect and did not require qualification by the datareviewer. The parent sample results associated with negative biases were non-detect and werequalified UJ,m, unless previously qualified due to LCS/LCSD percent recovery anomalies. Theseanomalies are considered minor and the qualified field sample results should be consideredusable as estimated values with a negative bias.

The surrogate spikes performed on samples MRC-SW13A-S and MRC-SW9B-S displayedpercent recoveries greater than the upper QC limits. The positive associated field sample resultswere qualified J+,s. These surrogate anomalies are considered minor and the qualified fieldsample results should be considered usable as estimated values with a positive bias.
