Pathways. Components, or Threats Not Scored

The ground water migration, soil exposure, and air migration pathways were not evaluated because they are
not expected to add significantly to the Hazard Ranking System (HRS) site score.

Ground Water Migration Pathway:

Although ground water contamination has been documented on site, the number of drinking water wells
located within a 4-mile radius of the site is low (Reference [Ref.] 31, p. 2-13, 2-14).

Soil Exposure Pathway:

Lead-contaminated soil has been documented on one residential property. In October 2003, an interim
removal action was completed on the property: the top 6 inches of soil were excavated from the property and
disposed of (Ref. 50, pp. ES-1, 2-3). Lead-contaminated soil may remain on the property (Ref. 51, Table 4
and Appendix A) since only the top 6 inches of soil were removed from the property and the results for
samples collected from below this depth indicated concentrations of lead greater than 400 milligrams per
kilogram (Refs. 50, pp. 1-2, 2-3; 51, Appendix A). Soil samples were collected from within the 100-year
flood plain of Hilliards Creek to evaluate whether periodic flooding transported contaminated sediments from
Hilliards Creek to the banks (flood plain) of Hilliards Creek (Ref. 51, pp. 5, 8). As documented in the other
sources section of this HRS documentation record, lead was detected in the flood plain soil samples at
concentrations exceeding three times the background concentration along Hilliards Creek from Gibbsboro
Road to sample location T-14, a distance of approximately 2,800 feet (Ref. 51, Figure 4; the other source
section of this HRS documentation record). Six areas of concern were identified including the Hilliards Creek
Wildlife Preserve (Ref. 51, p. 9). Many homes are located near the 100-year flood plain of Hilliards Creek.
There is the potential for the lead-contaminated sediment in Hilliards Creek to be carried by floods onto
residential properties located within or near the 100-year flood plain of Hilliards Creek (Ref. 97). However,
current reference documentation does not indicate that contaminated soil is located on additional residential
properties.

HRS DOCUMENTATION RECORD COVER SHEET (Continued)

Air Migration Pathway:

No air samples have been collected. Therefore, an observed release to the air migration pathway from on-site
sources can not be documented. As documented in Section 2.4.1 for Source 1, volatile organic compounds
(VOC) have been detected in free-phase product samples collected from ground water located near Buildings
55 and 67. VOCs also were detected in soil samples collected from Sources 1, 2, and 4, as documented in
Section 2.4.1 for each source. There is the potential for the VOCs in the source areas to release to air and into
occupied buildings.

General Location in the State: Central
Topographic Map:	Clementon, New Jersey

Latitude:	39.835525541° North

Longitude:	74.964976916°West

The coordinates of Sherwin-Williams/Hilliards Creek were calculated from the northwest corner of Building
67 shown on Reference 97.* The coordinates were measured using map interpolation from Clementon, New
Jersey Quadrangle, using ArcGIS 9© software. Universal Transverse Mercator (UTM) coordinates converted
to latitude and longitude NAD83 using CorpsCon software, US Army Corps of Engineers Topographic
Engineering Center (Ref. 9).

* The street address, coordinates, and contaminant locations presented in this HRS documentation record
identify the general site location. The information represents one or more locations U.S. Environmental
Protection Agency (EPA) considers part of the site based on the screening information EPA used to evaluate
the site for listing on the National Priorities List. EPA assigns national priorities from the known "releases
or threatened releases" of hazardous substances; thus, the focus is on the release, and not on precisely
delineated boundaries. A site is defined as an area where a hazardous substance has been "deposited, stored,
placed, or otherwise have come to be located." Generally, HRS scoring and the subsequent listing of a release
represent the initial determination that a certain area may need to be addressed under the Comprehensive
Environmental Response, Compensation, and Liability Act. Accordingly, EPA contemplates that the
preliminary description of site boundaries at the time of scoring will be refined as more information is
developed on the location of contamination.

SITE SUMMARY

The Sherwin-Williams/Hilliards Creek site is located in Gibbsboro, Camden County, New Jersey. The
Sherwin-Williams/Hilliards Creek site includes, but is not limited to, contaminated soil on and ground
water underlying the former Lucas Paint Works Plant (Lucas plant) and contaminated soil and sediment
associated with Hilliards Creek. The former Lucas plant encompassed 60 acres of land and was bounded
to the north by Silver Lake and Route 561; to the east by United States (US) Avenue; to the south by
vacant land, a cemetery, and Bridgewood Lake; and to the west by Clementon-Gibbsboro Road (Refs. 6, p.
2-1 and Figure 2-4; 9; 68, p. 2-1). Hilliards Creek, also known as Millard Creek, flows southwesterly
through the former Lucas plant, under Foster Avenue, then turns west under W. Clementon Road, receives
the outflow of Bridgewood Lake, and continues west to Kirkwood Lake. Approximately 1,000 feet
upstream from Kirkwood Lake, Hilliards Creek receives surface water flow from Nichols Creek. Hilliards
Creek merges with the Cooper River just before it enters Kirkwood Lake (Refs. 6, p. 2-11 and Figure 2-2;
9; see Reference 97, Sampling Location and Lucas Plant Area Map).

Hilliards Creek received surface water runoff and discharges from the Lucas plant (see Figure 2-4 in
Reference 6). The Lucas plant began operation in 1851 and it manufactured varnishes, lacquers, and lead-
based-paints, including dry colors, paste paints, and linseed oil liquid paints. Wastes generated from the
plant were disposed of in Hilliards Creek, on-site wastewater lagoons, the Route 561 Dump Site, and the
US Avenue Burn Site (Refs. 31, p. 2-5; 61, pp. 3, 4, 5). The Route 561 Dump Site and US Avenue Burn
Site have been evaluated as separate sites and are therefore not included in this Hazard Ranking System
(HRS) documentation record (Ref. 61, p. 5).

Ground water at the Lucas plant occurs in two distinct zones: the shallow zone (30 to 40 feet thick) and a
deeper zone (total thickness unknown). The two zones are separated by a silt unit that acts as a confining
layer (Ref. 31, p. 4-2). The saturated thickness of the shallow zone is approximately 30 to 40 feet. Depth
to ground water is between 1 to 15 feet below ground surface (bgs). The horizontal direction of ground
flow is generally to the south-southwest. Locally, Hilliards Creek, White Sand Branch, and Bridgewood
Lake act as discharge zones for shallow ground water (Ref. 31, p. 4-2).

Sherwin-Williams terminated production at the Lucas plant in late 1976. The entire operation and facility
were permanently closed on September 1, 1978 (Ref. 31, pp. 2-2, 2-6). Robert K. Scarborough purchased
a portion of the facility from Sherwin-Williams sometime between June 26, 1981, and September 7, 1983.
In 1983, Scarborough demolished most of the Sherwin-Williams facility and undertook various
construction projects (Refs. 31, p. 2-2; 32, p. 5). The Paints Works Corporate Associates I (the Paint
Works), a New Jersey-based corporation, purchased a portion of the plant from Sherwin-Williams
sometime between June 26, 1981, and September 7, 1983. The Paint Works re-graded the plant (Ref. 32,
p. 5). The Lucas plant is currently used as an office and light industrial park and is called the Paint Works
Corporate Center (the Paint Works) (Ref. 6, p. 2-1).

Current Conditions

In 1981, a majority of the land encompassing the former Lucas plant or Sherwin-Williams plant was sold
to Robert K. Scarborough and developed as a light industrial park known as "The Paint Works Corporate
Center" (Refs. 6, p. 2-1; 31, p. 1-1). Development of the property included demolition or renovation of
existing structures and construction of new office, manufacturing, and warehouse space (Ref. 31, p. 2-1).
The current layout is presented in Reference 31, Figure 2-2. The center is made up of nine buildings. As
of November 2001 when the RI/FS Work Plan was revised, 20 tenant companies occupied office,

16


-------
SITE SUMMARY (Continued)

warehouse, and manufacturing space at the park (Ref. 6, p.2-2). Two of the tenants used hazardous
materials including Academy Paints and Scotko Sign & Display Company. Both Academy Paints and
Scotko Sign & Display, Inc., were listed by EPA as large-quantity generators. Scotko was listed as
generating D001, F003, and F005 wastes. Both have terminated their lease and left the park (Ref. 6, p. 2-
6). According to Sherwin-Williams, as of July 2006 there are 53 tenants with approximately 720
employees occupying office and warehouse space, and there is no manufacturing activity at the facility.

The north boundary of the corporate center is bounded by Silver Lake, which discharges into Hilliards
Creek. Hilliards Creek transverses the corporate center in a northeast-southwest direction. The corporate
center is bisected by Foster Avenue. The portion of the corporate center north of Foster Avenue is
occupied by numerous buildings including former Buildings 14, 33, 55, 57, 58, and 82, a new building
paralleling Foster Avenue, and a shed. The grounds surrounding the buildings are paved parking lots. The
northernmost part of the corporate center along US Avenue, north of all the buildings, is a gravel parking
lot. The area immediately south of Foster Avenue is occupied by buildings and is surrounded by paved
parking lots (Ref. 31, p. 2-1 and Figure 3-2).

The corporate center is surrounded by residential properties (Ref. 31, p. 2-15). A public school, library,
and municipal offices are located approximately 0.2 mile west of the corporate center, along Kirkwood
Road. Silver Lake is located on the corporate center. A pedestrian walk surrounds Silver Lake, and a
shooting range is located on the southern shore of Bridgewood Lake. Bridgewood Lake is located south of
the corporate center along the south border of the Sherwin-Williams facility. Silver Lake discharges into
Hilliard Creek through an underground culvert system that crosses under the parking lot between the lake
and Foster Avenue. The creek returns to open flow 200 feet south of Foster Avenue (Ref. 31, p. 2-17).

Generally, the topographic gradient is from northeast to southeast. The corporate center is flat and graded
toward storm water collection points. Near Hilliards Creek and Bridgewood Lake, the topographic
gradient slopes gently toward these water bodies (Ref. 31, p. 2-8). Surface water runoff from the
northernmost portion of the corporate center discharges directly into Silver Lake. The north-central
portion of the corporate center is occupied by buildings and paved areas. Runoff generated in the area
between Silver Lake and Foster Avenue enters a network of catch basins and storm sewers, which
discharge into Hilliards Creek, immediately south of Foster Avenue (Ref. 31, p. 2-9).

Operational History: John Lucas and Company

The Lucas business was first established in March 1849 to import white lead, paints, and colors (Ref. 13,
p. 3). The company was called "Gibbsboro White Lead, Zinc, and Color Works" (Ref. 17, p. D-10). From
1851 to 1930, John Lucas and Company owned and operated a paint and varnish manufacturing facility at
the Lucas plant (Refs. 31, p. 2-2; 32, p. 2; 60, p. 6). The Lucas plant was constructed at the former
location of a sawmill and, subsequently, a grain mill (Refs. 13, p. 4; 31, p. 2-2; 60, p. 15). John Lucas and
Company developed and manufactured oil-based paints, varnishes, and lacquer (Ref. 31, p. 2-2).

The plant was expanded at various stages to accommodate new operations such as grinding white lead and
colors in oils (Ref. 60, pp. 19, 26, 30). A historical map that shows locations of old buildings and
structures is presented in Reference 6, Figure 2-4 and Refs. 3, 4, and 5. The expansions included more
than 53 buildings and occupied only a portion of the current 60-acre property (Refs. 14; 15; 31, p. 2-3). In
the early 1880s, the plant operations included dry color production, color grinding in oil, varnish
production, and production of ready-mixed oil paint (Ref. 60, p. 30). During World War II, John Lucas

17


-------
SITE SUMMARY (Continued)

and Company supplied protective finishes for many types of equipment, such as trucks, tanks, gun
carriages, and barracks. The company also supplied marine finishes to the Maritime Fleet (Ref. 13, p. 10).
Information on the constituents of marine finishes was not identified in the reference documentation.

The primary products manufactured by the John Lucas and company were white lead paint, varnish, and
lacquer. Other products included dry colors produced from chemical reactions, blending, filtering, and
drying; oil-based paints produced from grinding pigments in oil and adding thinners, oils, and hardeners;
and ready-mixed linseed oil paints produced from blending linseed oil with pigments and thinners (Refs.
31, p. 2-3; 60, pp. 6, 8, 12, 22, 26). A memorandum prepared by John Lucas lists the following as
components for Chinese blue paint manufactured by Lucas Paints: prussiate potash, copper sulphate,
sulphate of iron, clear nitric acid, and sulphuric acid (Ref. 11).

The manufacturing history of John Lucas and Company began in 1849, and dry colors were among the
first products manufactured (Refs. 12; 13, p. 1). Dry color was the largest operation at the Lucas plant
through the end of the 19th century (Ref. 60, p. 33). Chrome yellow and Prussian blue were the two major
pigments produced at the Lucas plant (Ref. 60, p. 37). John Lucas made the first chrome greens and
chrome yellows produced in America. Mr. Lucas also introduced the use of brightening agents. Paints
produced included white lead, white zinc, iron blues, Paris green, chrome orange, zinc yellow, lithol, para
and toluidine reds, scarlet and maroon lakes, and alizarine colors (Refs. 12; 13, p. 1; 60, pp. 11, 17, 19, 22,
23). Prussian blue, paste paints, pure linseed oil liquid paints, French greens, Swiss green, Chinese blue,
and laundry blue also were manufactured (Refs. 13, pp. 3, 6, 7; 17, p. D-ll; 60, pp. 17, 19, 22, 24).
Reference 16 provides a comprehensive list of paints and products manufactured by Lucas. The basic
pigments used by Lucas were lead and zinc oxides, white lead, non-lead chrome green, and chrome
yellow. White lead was ground at the plant (Refs. 8, p. 3; 60, pp. 1, 19 20, 21, 42). Lucas produced 24
different varieties of varnish (Ref. 60, pp. 22, 73).

Many of the buildings on the Lucas plant were used to store paint and drums. Materials stored included
varnish, colors, oil, lacquer, paint, dry colors, coal, and sludge (Refs. 4; 5; 14; 15, pp. 1 through 6; 60, p.
29) (see Figure 2-4 in Reference 6). Raw materials Lucas used included calcined acetate of lead, lead
oxide, zinc oxide, lead chromate, ferrous sulfate, sulfuric acid, linseed oil, and various paint solvents
(Refs. 31, p. 2-3; 60, pp. 10, 26). The operations south and southwest of Silver Lake involved
manufacturing, refining, storage, handling, and transporting hazardous substances above ground and
below ground. These areas contained drums of oils and varnishes and tank farms and railroad tankers of
lacquers, solvents, caustic solutions, and petroleum-based products. All the products were used in the
paint manufacturing industry (Ref. 10, p. 9).

During the 1880s, storage tanks for oils and oil-based paints were installed in the area of Tank Farm A. In
1887, a rail spur was installed at the facility to improve transportation and handling of raw materials and
finished goods (Ref. 31, pp. 2-3, 2-4).

Several disasters occurred at the Lucas plant, including a flood in 1940 and two fires between 1905 and
1949 (Refs. 13, p. 11; 31, p. 2-5; 32, p. 3). In 1905, a fire occurred in Building 32, the Varnish Filter
House, where varnish was thinned and filtered. The second fire occurred on September 18, 1915, inside
Building 39, which was used as a dry color paint mill at the time (Refs. 31, pp. 2-5, 2-6; 60, pp. 33, 66).

Operational History: Sherwin-Williams Company

18


-------
SITE SUMMARY (Continued)

In approximately 1930, Sherwin-Williams acquired control of Lucas plant; however, Mr. Lucas continued
to operate the plant until 1967 (Refs. 8, p. 1; 17, p. D-12; 31, p. 2-2; 32, p. 2). Sherwin-Williams operated
the Lucas plant from 1967 until production ended at the plant in late 1976 or early 1977 (Refs. 8, p. 1; 31,
p. 2-2; 32, p. 2). Sherwin-Williams closed the plant permanently on September 1, 1978 (Ref. 31, p. 2-2).

When it was owned and operated by Sherwin-Williams, the plant included an area for unloading raw
materials from railroad cars; tank farms for raw materials including storage tanks constructed prior to
1908; storage areas for drummed raw materials; an industrial and domestic wastewater treatment and
disposal system consisting of unlined percolation/settling lagoons; a solid waste disposal area for paint
sludges; an extensive system of pipes to transport raw materials; and a drum cleaning area. Raw materials
were mixed and processed in a number of specialized buildings in the plant (Refs. 4; 5; 32, p. 2) (see
Figure 2-4 in Reference 6). Raw materials stored on the plant included V.M.&P. naphtha (8,000 gallons),
xylene (26,000 gallons), mineral spirits (100,000 gallons), toluene and solvent blends (65,000 gallons),
and aromatic naphtha (1,500 gallons) (Refs. 4; 5; 31, Table 2-2; 32, pp. 2, 3).

From 1967, the plant manufactured interior and exterior house paint, latex, and oil-based interior and
exterior house paint until 1975, lacquer finishes until 1975, and polymerized oils and formulated dyes until
1972 (Ref. 8, p. 1).

Sherwin-Williams expanded the operations at the plant. Office and manufacturing facilities occupied one-
third of the property, with the center of the plant located around Foster Avenue. During the 1930s,
Sherwin-Williams terminated dry color production, but the plant continued to produce oil-based paints,
varnishes, lacquers, and emulsion paints until December 1975. In 1956, Sherwin-Williams began
production of alkyd or synthetic varnish, but this operation terminated in December 1975. The plant
produced emulsion paints only between December 1975 and early 1977 (Ref. 31, p. 2-4).

Raw products used from approximately the late 1950s included titanium dioxide, a major component for
products. The following products were used in resin production: polymers, pigments, linseed oil, soya oil,
ray linseed oil, mineral spirits, refined linseed soil, glycerine, V.M.&P. naphtha, and xylene (used in resin
production). The following materials were used in lacquer production: isobutyl alcohol; c.p. acetone;
methyl amyl acetate; isopropyl acetate; xylene; lacquer solvent; toluene; toluene-based solvent blend;
methyl ethyl ketone; ethyl acetate; methyl butyl ketone; and aromatic naptha. Pulp pigments, liquid
mixers, and solvents were used in production of Sher-dye (Ref. 8, p. 2).

Raw materials were stored in aboveground storage tanks (ASTs) and underground storage tanks (USTs) in
two areas on the plant: Tank Farm Areas A and B. Raw materials (paint pigments) were also stored in 55-
gallon drums. Raw materials and finished goods were typically stored in former Buildings 55, 56, 57, 58,
62, and 67 (Ref. 31, p. 2-4 and Figure 2-2; 4; 5 ; 60, p. 68) (see Reference 6, Figure 2-4 and Reference 31,
Figure 3-2). Between 1950 and 1977, wastewater generated from the manufacturing process was treated
and disposed of in four unlined lagoons on the southern portion of the property (Ref. 31, p. 2-5) (see
Reference 6, Figure 2-4 and Reference 31, Figure 3-2).

Several fires occurred at the plant; according to Sherwin-Williams, fires occurred in 1905, 1915, 1930, and
1949. The fire on February 21, 1930 destroyed Building 36, a warehouse used to store raw materials.
After the fire in the former Building 36, a concrete foundation pad was used for exterior storage of
drummed materials. Subsequently, on July 30, 1949, a fire destroyed 1,000 drums of nitrocellulose and
lacquer stored on the concrete pad at Building 36 (Refs. 31, pp. 2-5, 2-6; 60, pp. 33, 66).

SITE SUMMARY (Continued)

Operational History: Robert K. Scarborough

In June 1981, a majority of the Lucas plant was sold to developer Robert K. Scarborough. Scarborough
developed the former plant into a light industrial complex named The Paint Works Corporate Center. The
center is made up of nine buildings (Ref. 31, p. 2-16). At present, 20 tenant companies occupy office,
warehouse, and manufacturing space on the former plant property. In December 1997, a portion of the
former plant property was sold to Brandywine Reality Trust (Refs. 18, p. 1-1; 31, p. 2-2).

History of Investigations:

In January 1990, the New Jersey Department of Environmental Protection (NJDEP) issued a Spill Act
Directive to Scarborough (the owner of the Lucas plant property) and Sherwin-Williams Corporation (the
former owner of the Lucas plant property) requiring that a remedial investigation and feasibility study
(RI/FS) be conducted at the former Lucas plant and immediately adjacent lands. Sherwin-Williams
subsequently entered into an Administrative Consent Order (ACO) with NJDEP to conduct the RI/FS
(Ref. 31, p. 1-1).

The RI report covers activities conducted at the Lucas plant from August 1991 through January 2000
(Refs. 31, pp. 1-1, 1-2; 59, Appendix II, p. 1117). Seeps located on the facility were identified as an area of
Immediate Environmental Concern (IEC). Sherwin-Williams entered into an ACO with NJDEP to address
this IEC. A soil vapor extraction (SVE) system and a free-phase product removal system were installed in
the area of the seeps, and a free-product removal system was installed in the area of former Tank Farm A
(Ref. 31, p. 1-5). According to Sherwin-Williams, it has conducted "significant investigations at The Paint
Works and Hilliards Creek under EPA since 2000." Sherwin-Williams submitted Attachment 1 to its
comments listing a series of past and ongoing activities conducted by Sherwin Williams (EPA-HQ-
SFUND-2006-0242-0014).

2.2 SOURCE CHARACTERIZATION
2.2.1 SOURCE IDENTIFICATION
Name of source: Free-Phase Product
Number of source: 1
Source Type: Other

This source includes free-phase product present in ground water underlying the former Lucas plant in the
areas of Building 50, Building 67, and Tank Farm A (Ref. 31, pp. ES-6, 3-30, 4-18, 4-19, 4-20). The three
locations where free-phase product have been identified are referred to as seeps in reference
documentation and are shown on Figure 2-2 in Reference 31 as seep areas. The free-phase product is
composed of benzene, ethylbenzene, xylene, naphthalene, and 2-methylnaphthalene (Ref. 31, p. 4-25 and
Table 4-20). Analysis of the product indicates that it is paint thinner (Ref. 31, p. 4-26) because there was
no evidence of any organolead or organomanganese in the samples of the product (Ref. 31, p. 4-27). A
free-phase product recovery (FPR) and soil vapor extraction (SVE) system have been installed in the area
of Buildings 50 and 67 to recover the free-phase product (Refs. 31, pp. 3-24, 3-25; 48, Figure 2-1). (A
separate gasoline ground water plume is located west of Building 67 and is not evaluated in this HRS
documentation record [Ref. 31, Figure 3-2 and Appendix K, Figures 4-11 and 4-12].)

The potential sources of the free-phase product plume are Tank Farm A (Ref. 31, pp. 2-3, 2-4, and Table
2-2); operations in Lucas plant Buildings 50, 55, and 67 (formerly Building 36) including the transfer and
temporary storage of process chemicals (Refs. 6, Figure 2-4; 31, Figure 3-2; 59, Appendix II, p. 11-57; 60,
p. 68) and storage of product in Building 36 or platform 36 (Ref. 6, Figure 2-4); a 6-inch terra-cotta pipe
leading from Building 50 (Paint Works Maintenance Shop) (Ref. 18, pp. 3-4, 3-5); two 6,000-gallon
vertical steel AST formerly containing mineral spirits 66-2 and 802-15 alkyd resin adjacent to Building 50
(Ref. 18, pp. 3-5, 4-1); hazardous material and hazardous waste storage adjacent to Building 50 (Ref. 31,
p. 6-3); the Lucas plant solvent railroad and truck tank unloading station on the north side of Building 67
(Refs. 7, pp. 4 through 11, 17; 6, Figure 2-4); storage areas for empty and dirty drums east of Building 67
(Ref. 5); contamination in the Building 67 parking lot (Ref. 31, p. 3-3); leakage of storage lagoons or
drums that were once stored behind Building 67 (between Building 67 and 50); spillage from tank cars
(Ref. 10, pp. 18, 19); and two USTs, one for oil and another for solvent, located in the parking lot located
east of Building 67 (Ref. 65, p. 1). Storage lagoons are identified as a source in Reference 10, pages 18
and 19; however, no storage lagoons in the area of Buildings 50 and 67 are observed in aerial photographs
or discussed in the reports for any other investigations at the plant.

The free-phase product plume present in the ground water underlying Buildings 50 and 67 and former
Tank Farm A, has been characterized by the collection of product samples and soil samples as documented
in the sections below. Numerous investigations have been conducted in the area of the free-phase product
plume associated with Buildings 50 and 67. A summary of those investigations is provided in the section
below.

Free-Phase Product - Buildings 50 and 67

The reference documentation for the free-phase product identified product on west side of Building 50 and
on the north and east sides of Building 67. The narrative discussion in the reference documentation
describes the two free-phase product locations together. It is therefore, difficult to separate the discussion
of the free-phase product in area of Building 50 from the free-phase product in area of Building 67 (Ref.
31, Figure 2-2 [shown as seep areas], pp. 3-2 through 3-7, 3-8 through 3-12, 3-22, 3-23 through 3-25, 4-18
through 4-24, 5-5, 5-6). The two locations of free-phase product have a similar migration pathway. Free-
phase product released to Hilliards Creek at the location where the creek emerges from underground, south
of Foster Avenue, resulted from the migration of free-phase product into the storm sewer system from
free-phase product located on the west side of Building 50 and east side of Building 67 (Ref. 31, p 3-6)
(shown as seep areas on Figure 2-2 of Reference 31).

The free-phase product plume in ground water near Buildings 50 and 67 was initially identified in 1983
when an oily substance was observed in the parking lot between former Buildings 50 (currently police
station) and 67 (also known as the Academy Paints Building). The oily substance flowed overland to a
storm water catch basin in the parking lot then into a storm sewer that discharged into Hilliards Creek
(Refs. 32, p. 5; 65, pp. 1, 2, 3). The product was observed on many occasions during construction of the
corporate center that now occupies the former Lucas plant (Ref. 65, p. 1).

In February 1985 and 1987, product was observed in the parking lot between Buildings 50 and 67 and
flowing from the eastern bank of Hilliards Creek (Refs. 6, Figure 2-4; 10, pp. 1, 2; 31, p. 3-3 and Figures
2-2 and 3-2; 32, pp. 5, 6).

Note: Numerous reports describing investigations conducted in this area refer to Building 67 as the former
Academy Paints Building (former occupants of the building) and Building 50 as the Gibbsboro Police
Station Building (current occupants of the building). Building 67 is the former location of Lucas plant
Building 36 (Refs. 6, Figure 2-4; 31, Figure 3-2). On February 21, 1930, a fire destroyed Building 36,
which was a warehouse used to store raw materials. After the fire, the concrete foundation pad for the
former Building 36 was used for exterior storage of drummed materials (Refs. 31, pp. 2-5, 2-6; 60, pp. 33,
66; 7, p. 5). Lucas used Building 50 as a garage (Ref. 60, p. 99). Hazardous material and hazardous waste
were stored adjacent to Building 50 (Ref. 31, p. 6-3).

In 1987, after free-phase product was observed flowing into Hilliards Creek, the New Jersey Department
of Water Resources (DWR) issued a directive to Sherwin-Williams requesting that actions be taken to
mitigate the release to Hilliards Creek (Ref. 10, p. 1). Sherwin-Williams refused to comply with the DWR
directive. However, the owner of the property at the time, Scarborough, procured an environmental
contractor to mitigate the release. An enclosure was constructed to prevent product from flowing through
the parking lot into a storm water inlet and finally into Hilliards Creek. The product in the enclosure was
pumped out and disposed of off the property. As of July 1987, 4,200 gallons of product were collected
and disposed of off the property (Refs. 10, p. 2; 32, pp. 6, 7).

Observations during the 1987 investigations included product flowing from the bank of Hilliards Creek,
product flowing from cracks in the pavement in the parking lot between Buildings 50 and 67 and other
areas in the parking lot, and severe contamination in soil (Ref. 10, pp. 9, 18). Oil-absorbent booms and
filter fences were installed in the area surrounding the seep and at the rip-rap channel and storm water

conveyance to collect free-phase product. The rip-rap channel collected surface water runoff from the
parking lot and directed the water to Hilliards Creek. A berm was constructed around the seep in the
parking lot, and a temporary bypass was constructed in Hilliards Creek, conveying Hilliards Creek around
the product that emanated from the creek. A bulkhead was constructed around the perimeter of the
product that emanated into the creek (Ref. 10, pp. 2, 3).

Free-phase product entered the storm sewer system when the water table was high, indicating the product
is associated with a ground water plume underlying the Lucas plant and extending to Hilliards Creek
(Refs. 6, p. 3-47; 18, p. 2-3). On February 19, 1988, and again on February 25, 1988, NJDEP observed
product discharging into Hilliards Creek (Refs. 36; 37).

In 1989, NJDEP submitted a sample of the product to an analytical laboratory for comparison to known
petroleum and solvent products. The comparison indicated that constituents in the product sample were
most similar to a mixture of solvents and to 627 solvent (a solvent), Varsol 18 (an oil), and mineral spirits
(a solvent) (Refs. 63, pp. 1, 2; 56).

In 1994, free-phase product began to enter a storm sewer north of Building 67. The free-phase product
was removed (Ref. 31, p. 3-22). Based on the potential for repeated seepage of product into a leaky storm
water system, NJDEP identified this area as an area of IEC. NJDEP issued a directive to Sherwin-
Williams to address this IEC. A FPR and SVE system were installed after a focused feasibility study
(FFS) and a remedial action work plan (RAW) had been completed for the area of free-phase product.
Passive skimmers were installed in the thickest free-phase product to recover mobile product. The leaky
portion of the storm sewer was excavated and replaced with a sealed system to prevent infiltration of free-
phase product. Free-phase product removal equipment was also installed in the area of former Tank Farm
A (Ref. 31, pp. 1-5, 3-22, 3-23).

In 1995, Sherwin-Williams entered into an ACO with NJDEP to conduct an RI/FS in the area os Source 1
and to remove free-phase product (Refs. 18, p. 1-1; 61).

Sherwin-Williams conducted the following remedial actions in the area of Source 1:

Removal and disposal of the former wooden containment structure installed by the owner of the
property when the contamination was discovered.

Removal and disposal of contaminated soils and ground water from the area east of Hilliards
Creek and west of the police station (Building 50) (Ref. 18, p. 1-1).

Excavation of exploratory trenches in the area immediately west of the police station building
(Building 50).

Replacement of storm sewer immediately north of the Building 67.

Installation of a FPR and SVE system on the east side of Building 67 (Refs. 6, pp. 3-47 through 3-
52; 18, p. 1-2; 31, pp. 3-22, 3-23, 3-24; 48, Figure 2-1).

The aboveground treatment system consisted of a free-phase product collection and holding tank and the
SVE/Thermal Oxidizer skid (Ref. 31, p. 3-25).

In 1996, while investigating the free-phase product plume at Buildings 50 and 67, a 6-inch terra-cotta pipe
leading from Building 50 to Hilliards Creek was uncovered. The pipe end was encountered 3 feet bgs, and
the pipe extended 10 feet to the west from Building 50 toward Hilliards Creek. The end of the pipe was
exposed. The pipe terminated abruptly, and no french drain or sump was found at its terminus. Free-
phase product was present in the interior of the pipe. The pipe was traced to a floor drain in Building 50.
The pipe was above the water table; therefore, the product found in the pipe was not introduced by
contaminated ground water. The seep on the west side of Building 50 was attributed to the pipe (Ref. 18,
pp. 3-4, 3-5, 4-1). Since John Lucas and Company used Building 50 as a garage, the free-phase product
may have resulted from the discharge of petroleum-type wastes (Refs. 6, Figure 2-4; 60, p. 99).

Also while investigating the free-phase product plume at Buildings 50 and 67, additional product was
identified in the former location of two ASTs used by Academy Paint, a tenant of Building 67, to store
mineral spirits 66-2 and 802-15 alkyd resin (Ref. 18, pp. 3-4, 3-5, 4-1, Figure 3-1). The AST were located
on the south side of Building 50 (Ref. 18, Figure 3-1).

During the removal action in 1996, Sherwin-Williams recovered 13,910 gallons of the mixture of
nonhazardous liquid, water, and oil from Buildings 50 and 67 free-phase product plume and disposed of
the material off the property (Refs. 18, pp. ES-1, 3-5; 31, p. 3-24). After remedial action was completed,
residual contamination remained in the area of the Lucas plant property and Hilliards Creek (Refs. 18, pp.
ES-1, 4-1; 31, Figure 3-2).

In November 1997, the installation of the FPR and SVE system was completed east and north of Building
67 and south of Building 50 (Ref. 48, pp. 1-1, 2-2, 3-1, Figure 2-1). As of June 20, 2002, a total of 44,785
gallons of product/water mixture have been recovered and removed off site for disposal since startup of the
system in November 1997. Approximately 8,275 gallons of this total volume collected was primarily
product from the product recovery tank. The remaining 36,510 gallons of product/water mixture were
collected during the ground water seep response and recovery efforts associated with the FPR and SVE
system (Ref. 48, p. 2-1).

On April 9, 2002, free-phase product from the free-phase product recovery system was observed in the
storm water drain north of Building 67 and in Hilliards Creek. Product was pumped out of the storm water
drain, and additional measures were taken to prevent further releases to the drain and Hilliards Creek
(Refs. 48, p. 2-3; 72, pp. 2, 4; 73, pp. 2, 4).

Location of the source, with reference to a map of the site: Source 1 is located on the west side of
Building 50, on the east and southeast sides of Building 67, the storm sewer system north of Building 67,
and in the area of Tank Farm A. Figure 2-2 of Reference 31 shows the three seep areas: one on the west
side of Building 50, one on the east side of Building 67, and one in the area of Tank Farm A and the
location of the sewer. The seep areas are the locations where free-phase product was observed at the
ground surface or in on-site monitoring wells.

Release to ground water: Migration of hazardous substances from the source area has been documented;
therefore, a containment factor value of 10 is assigned to this source. Additionally, as documented in the
section above, the source does not have a liner or containment system (Ref. 1, Table 3-2).

Release via overland migration and/or flood: Migration of hazardous substances from the source area
has been documented; therefore, a containment factor value of 10 is assigned to this source. Additionally,
as documented in the section above, a maintained engineered cover, or functioning and maintained run-on
control system and runoff management system, is not associated with Source 1 (Ref. 1, Table 4-2).

Gas release to air: The air migration pathway was not scored.

2.4 WASTE CHARACTERISTICS
2.4.1 Hazardous Substances:

Samples of free-phase product and soil are used to characterize the hazardous substances associated with
Source 1. The soil samples were collected from locations where free-phase product was observed. The
sections below provide a description and documentation of the free-phase product and soil samples
collected to characterize Source 1.

Free-Phase Product

On February 7, 1985, NJDEP personnel collected an aqueous sample of product while it was discharging
into Hilliards Creek (Ref. 32, pp. 5, 6). The following hazardous substances were detected in product
sample: 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, naphthalene, xylenes, ethylbenzene, cumene,
and tetrachloroethene (Ref. 32, pp. 6, 7).

In February 1987, product was observed in the parking lot between Buildings 50 and 67 and flowing from
the eastern bank of Hilliards Creek. An aqueous sample was collected from the product flowing into
Hilliards Creek, and a sediment sample was collected below the bituminous layer of the parking lot where
the product was observed (Refs. 6, Figure 2-4; 10, pp. 1, 2; 31, p. 3-3 and Figures 2-2 and 3-2).

The free-phase product ground water plume was investigated during five phases of the RI for the Lucas
plant (Ref. 31, p. 3-3). The RI identifies five areas of environmental concern (AEC). The seep areas or
areas where free-phase product was observed at the surface in the areas of Buildings 50 and 67, were
identified as AEC III. AEC III was combined with AEC I, Tank Farm A, because of similarities in the
nature of contaminants (Ref. 31, p. 3-1). Figure 3-1 of Reference 31 shows the AECs, and Figure 2-2 of
Reference 31 shows the location of three seeps one on the west side of Building 50, one on the east side of
Building 67, and one in the southern section of the former location of Tank Farm A.

The RI report for the five phases of the investigation refers to AEC I/III when presenting analytical data
collected for the free-phase product ground water plume. Figure 3-2 of Reference 31 was used to identify
sampling locations specifically associated with the free-phase product.

During Phase II activities, from June 1993 through October 1993, three well points (WP-1, WP-2, and
WP-3) were installed to delineate the free-phase product ground water plume detected in MW-13 (Ref. 31,
pp. 3-3, 3-15). Samples of free-phase product were collected from the MW-11 (located on the southern
end of Tank Farm A) and MW-13 (located east of Building 67) (Ref. 31, p. 3-17, Figure 3-2). Analytical
results for the product sample collected from MW-11 on August 6, 1993 indicated the presence of 2-
methylnaphthalene (360 milligrams per liter [mg/L]), 4-chloroaniline (320 mg/L), naphthalene (930
mg/L), chlorobenzene (100 mg/L), ethylbenzene (at an estimated concentration of 520 mg/L), and xylene
(at 4,600 mg/L) (Ref. 31, Table 4-20). The product sample collected from MW-13 on August 6, 1993
contained 2-methylnaphthalene (1,800 mg/L), naphthalene (6,200 mg/L), benzene (at 110 mg/L),
ethylbenzene (1,200 mg/L), and xylene (2,100 mg/L) (Ref. 31, Table 4-20).

During Phase III activities, from July 1995 through August 1995, 45 hand-augered borings were located
throughout the seep area to attempt to delineate the extent of free-phase product through photoionization

detector (PID) field screening and visual observation. No samples were collected from these locations
(Ref. 31, pp. 3-3, 3-18). Additional monitoring wells were installed, and two rounds of ground water
samples were collected (Ref. 31, p. 3-19). On July 14, 1995, samples of the free-phase product were
collected from the MW-11 (located on the southern end of Tank Farm A), MW-13 (located east of
Building 67), and MW-21 (southeast of Building 67) (Ref. 31, p. 3-17, Figure 3-2). Anaytical results for
the product sample collected from MW-11 indicated the presence of naphthalene (at an estimated
concentration of 600 mg/L), ethylbenzene (66 mg/L), and xylene (2,500 mg/L). The product sample
collected from MW-13 contained naphthalene (at 3,200 mg/L), benzene (at 570 mg/L), ethylbenzene (at
1,400 mg/L), and xylene (at 7,500 mg/L). Analytical results for the product sample collected from MW-
26 indicated 2-methylnaphthalene (at an estimated concentration of 460 mg/L), naphthalene (1,600 mg/L),
and xylene (420 mg/L) (Ref. 31, Table 4-20).

Also during the Phase III activities, free-phase product was measured for the mobile thickness of the
product, the volume of recoverable product, and the recharge rates of the product (Ref. 31, p. 3-20). A
bail-down test was conducted to identify the thickness of the product (Ref. 31, Appendix K, Tables El
through E4).

The bail-down test completed in WP-3 in the area of the Building 50 indicated that the thickness of the
product in July 1995 as 0.33 foot and in August 1995 as 0.48 foot (Ref. 31, Figures 4-11 and 4-12). The
bail-down test completed in the area of the Building 67 indicated that the thickness of the product in July
1995 at MW-21 as 2.21 feet, atMW-13Ras 0.98 foot, and atWP-1 as 1.33 feet (Ref. 31, Figure 4-11). In
August 1995 the thickness of product was recorded at MW-21 as 0.66 foot, at MW-13R as 1.28 feet, and
at WP-1 as 1.33 feet (Ref. 31, Figure 4-12). The bail-down test completed in MW-11 in the area of the
Tank Farm A identified the thickness of product as 1.47 feet in July 1995 and 0.45 foot in August 1995
(Ref. 31, Appendix K, Table E2, and Figures 4-11 and 4-12). The lateral extent of three separate product
plumes in ground water are shown on Figures 4-11 and 4-12, Appendix K, Reference 31. The plumes are
considered separate because of the absence of product in the monitoring wells located between the plumes
(Ref. 31, p. 4-20).

The hazardous substance and concentrations detected in product samples collected from MW-11, in the
area of Tank Farm A, and from MW-13, in the area of Building 67 are similar (Ref. 31, Table 4-20, Figure
3-2). The fingerprint analysis of a sample of free-phase product from the storm sewer indicated that the
product most closely resembled degraded mineral spirits (Ref. 75, p. 15). Therefore, the product in ground
water in the areas of Tank Farm A and Building 67 may be from the release of mineral spirits from Tank
Farm A and Building 67. Both areas were used for the storage of mineral spirits (Refs. 4; 5; 6; 31, 2-4,
Table 2-2, Figure 2-2; 60, pp. 68 and 99).

According to the RI report, the source of free-phase product on the west side of Building 50 may be from
the discharge of waste oils to soils over time, migration of free-phase product from the former Academy
Paints hazardous materials storage area, or the Lucas maintenance shop formerly located in Building 50
(Ref. 31, pp. 4-23 and 4-24).

The RI report provides a discussion of the composition of the free-phase product. Much of the analytical
data supporting the discussion are not in the RI report. Analytical data are presented for product samples
collected from MW-11, MW-13, MW-21, and MW-26 in Table 4-20 of the RI report. The report stated
that xylene was the VOC detected at the highest concentration, and of the base/neutral acids, naphthalene

27

was detected at the highest concentration. The majority of the product constituents are tentatively
identified compounds (TIC). VOC TICs consist primarily of unknown substituted benzenes. Semivolatile
organic compound (SVOC) TICs include cycloalkanes, alkanes, benzenes, and unknown polycyclic
aromatic hydrocarbons (PAH) (Ref. 31, p. 4-25). Two free-phase product samples collected from MW-11
and SVE Vent No. 6 located west of Building 67 were analyzed by American Society for Testing and
Materials (ASTM) D5134 (Component Analysis) (Refs. 31, p. 4-26, Figure 3-2; 48, Figure 2-1). The
ASTM D5134 analysis provided identification of an exhaustive list (the list was not provided in the RI
report) of hydrocarbon compounds, that are not typically analyzed for and quantified by routine SW846
methods. The result of the free-phase product analyses were compared to the results of analyses of fresh
samples of gasoline and paint-thinner. The comparison was done by principal component analysis (PCA).
The PCA suggested that the samples were more related to paint-thinner rather than gasoline. However,
because the comparison was of unweathered and degraded standard against weathered and biodegraded
environmental samples, the correlation was regarded with limited confidence (Ref. 31, p. 4-26).

One ground water sample (MW-36 located 150 feet south of Building 67) was collected and analyzed by
Modified EPA Method 8015 (capillary gas chromatography). No free-phase hydrocarbons could be
recovered from the ground water sample (Ref. 31, p. 4-26, Figure 3-2).

The RI report states that 14 free-phase product samples were analyzed for petroleum hydrocarbon
products. Analytical data for the analysis of the product samples are not presented in the RI report. No
evidence of the presence of any organolead or organomanganese compounds were found in any of the
free-phase product samples. Two free-phase product samples collected from SVE-3 and MW-36, located
east and south of Building 67, respectively, contained no petroleum product (Refs. 31, p. 4-27, Figure 3-2;
48, Figure 2-1). (Note: The location and definition of SVE-3 is not in the RI report. SVE probably
indicates soil vapor extraction and the number represents the vent number as shown on Figure 2-1 of
Reference 48). The report indicates that analytical results for product samples revealed the presence of a
biodegraded, low boiling point petroleum hydrocarbon (Ref. 31, p. 4-27). From the report is not clear
where these product samples were collected. However, the report does indicate that the product in the area
of Source 1 may be a mixture of solvents and waste petroleum product.

On April 9, 2002, free-phase product from the FPR and SVE system was observed in the storm water
system (catch basin A and inlet C) and rip-rap north of Building 67 and in Hilliards Creek. The product
was pumped out of the storm water drain, and additional measures were taken to prevent further releases to
the drain and Hilliards Creek (Refs. 48, p. 2-3; 72, pp. 2, 4; 73, pp. 2, 4). As shown on Figure 2-4 of
Reference 48, inlet A is the catch basin in the parking lot north of Building 67 that drains to the storm
sewer that runs from east to west to rip-rap and finally to Hilliards Creek. Inlet C is located on the western
end to the storm sewer system just east of the discharge point of the storm water system to the rip-rap (Ref.
48, Figure 2-4). Figure 2-1 of Reference 48 shows the location of the vertical vents and the layout of the
FPR and SVE system.

On April 10, 2002, samples of the free-phase product were collected and analyzed for VOCs, petroleum
products, and fingerprinted (Ref. 75, pp. 2, 4, 5). The concentrations of hazardous substances detected in
the product sample are in the units of micrograms per kilogram (j^ig/kg) indicating that the sample was
analyzed as a solid. Analytical results for the samples indicated the presence of benzene (up to 240,000
(ig/kg), ethylbenzene (up to 4,600,000 |_ig/kg). xylene (up to 26,000,000 |_ig/kg). naphthalene (up to
1,800,000 |ag/kg). 2-methylnaphthalene (up to an estimated concentration of 400,000 |_ig/kg). and

numerous TICs (Ref. 75, pp. 6, 7, 8). The fingerprint analysis indicated that the product samples most
closely resembled degraded mineral spirits (Ref. 75, p. 15).

Analytical results for the wastewater sample from the product tank indicated an estimated concentration of
benzene and ethylbenzene and the presence of m/p xylenes, naphthalene, and 2-methylnaphthalene (Refs.
76, pp. 8, 9; 77, p. 35). Metals detected in the product tank include aluminum, arsenic, chromium, copper,
iron, lead, magnesium, manganese, selenium, and zinc (Ref. 77, p. 75). The toxicity characteristic
leaching procedure (TCLP) analysis revealed benzene (230 micrograms per liter [jj.g/L]) (Ref. 77, p. 31).
The inlet C sample analysis revealed an estimated concentration of benzene and the presence of
ethylbenzene, m/p- xylenes, naphthalene, and 2-methylnaphthalene (Refs. 76, pp. 10, 11; 77, p. 39). The
only TCLP metal detected in the inlet C sample was lead (455 j^ig/L) (Ref. 77, p. 82). The inlet C water
sample analysis revealed an estimated concentration of benzene, the presence of ethylbenzene and m/p-
xylenes, and estimated concentrations of naphthalene, 2-methylnaphthalene, and fluoranthene (Ref. 76, pp.
12, 13, 19, 20). Metals were also detected in the inlet C water sample, including aluminum, arsenic,
barium, chromium, copper, iron, lead, magnesium, manganese, and zinc (Ref. 77, p. 76).

As of June 30, 2002, the FPR system recovered approximately 44,785 gallons of product and /or water
since startup of the recovery system in November 1997. Approximately 8,275 gallons of this total volume
collected is primarily product from the product recovery tank. The remaining 36,510 gallons or
product/water mix were collected during the ground water seep response and recovery efforts associated
with inlets A and C (Ref. 48, p. 2-1).

In May 2003, EPA's environmental consultant collected samples of the free-phase product mixed with
water from basin A, inlet C, and the rip-rap. The samples were analyzed for target compound list (TCL)
VOCs, SVOC, pesticides and polychlorinated biphenyls (PCB), target analyte list (TAL) metals and
cyanide, gasoline range organics (GRO), diesel range organics (DRO), percent sulfur, percent ash,
Kjeldahl nitrogen, pH, and flashpoint. The analytical results confirmed the presence of benzene,
ethylbenzene, xylene, naphthalene, and 2-methylnaphthalene (Ref. 78, pp. 16, 11). Other constituents of
the product sample included the following metals: aluminum (up to 9,150 (ig/L). arsenic (up to 51.2
(ig/L), barium (up to 408 (ig/L). chromium (up to 33.3 (ig/L). copper (up to 79.0 (ig/L). iron (up to 95,200
(ig/L), lead (up to 139 (ig/L). magnesium (up to 23,000 (ig/L). manganese (up to 1,380 (ig/L). and zinc (up
to 413 jig/L) (Ref. 78, pp. 15, 16).

Hazardous substances associated with the analytical results from product samples collected from Source 1
and discussed above are summarized in Table 1 (Ref. 31, pp. 4-18 through 4-24). As documented in Table
1, free-phase product samples were collected from seeps (product) emanating from the ground surface,
monitoring wells, and the FPR and SVE system. The analytical data presented in Table 1 from Reference

31	are from the analysis of free-phase product samples collected from on-site monitoring wells. Reference

32	provides analytical data for the analysis of a discharge to a creek. The seep (free-phase product) was
continuously discharging into the creek (Ref. 32, pp. 5, 6). The analytical data presented in References. 76
and 77 are for a product sample collected from the product tank associated with the FPR system, inlet C,
and rip-rap area where the storm sewer discharges (Refs. 77, p. 2; 48, Figure 2-4). The analytical data
presented in Reference 78 are from basin A (the storm sewer basin in the parking lot adjacent to Building
67), inlet C, and the rip-rap area (Refs. 78, p. 1; 79). The analytical data presented in Reference 79 are
from a sample collected from the product tank associated with the FPR system and a bi-phase sample
collected from inlet C (an inlet in the storm sewer) (Refs. 48, Figure 2-4; 76, p. 1).

Soil Samples - Source 1
1987 Investigation

In 1987, contaminated soil was identified in the area of Buildings 50 and 67 during a subsurface soil
investigation (Ref. 10, p. 5). The source of the contaminated soil is the free-phase product. Soil samples
were analyzed for priority pollutants and total petroleum hydrocarbons (Ref. 10, p. 6), revealing the
presence of petroleum hydrocarbons, VOCs (xylene), SVOCs [pentachlorophenol, di-n-butyl phthalate,
bis(2-ethylhexyl)phthalate)], cyanide, chromium, copper, and lead (Ref. 10, pp. 10 and 25 through 39).

Remedial Investigation

Hazardous substances associated with Source 1 were identified during numerous soil sampling
investigations conducted in the area of the free-phase product ground water plume. The most recent

32


-------
SD - Characterization and Containment

Source No.: 1

investigation was a five-phase RI for the Lucas plant (Ref. 31, p. 3-3). The soil samples collected during
the RI are used to characterize Source 1 because the soil contamination is a result of the ground water
plume. The RI identifies Source 1 as AEC I/III (Ref. 31, p. 3-3 to 3-6). The RI report refers to AEC I/III
when soil samples were collected from Source 1. Figure 3-2, in Reference 31, was used to identify soil
sampling locations specifically associated with Source 1, free-phase product.

Soil samples were collected from Source 1 during three phases of the RI as described in the sections
below.

Phase I RI

Soil samples were collected in the area of Source 1 (AEC I/III) (Ref. 31, p. 3-7) from August 1991 through
lanuary 1992, during a Phase I RI for the Lucas plant (Ref. 31, p. 3-3). The Phase I RI focused in the seep
area (ground water plume in the area of Buildings 50 and 67) and Tank Farm A. Four test borings (TB-6,
TB-7, B-13, and TB-14) were drilled in the area of the free-phase product identified near Building 67 (Ref.
31, Figure 3-2). Two soil samples were collected from each boring at 0 to 2 feet below the bgs and at the
water table. The samples were analyzed for Priority Pollutant Volatile Organic Analysis plus 15-non
target compounds (PP VOA+15), Priority Pollutant Base Neutral Analysis (PP BNA), lead, chromium, and
barium. Two of the test borings were converted into monitoring wells. The monitoring wells, MW-13 and
MW-14, were sampled and analyzed for PP VOA+15, PP BNA, lead, chromium, barium, and phenols
(Ref. 31, p. 3-11). Free-phase product was identified in both MW-13 and MW-14 (Ref. 31, p. 4-18, Table
4-20). MW-14 is located adjacent to the storm sewer systems where free-phase product has been
recovered. The storm system is known to leak product to the surrounding area (Ref. 31, pp. 1-5, 3-22, 3-
23, Figure 3-2).

Six soil borings (TB-1 through TB-4, TB-11 [converted to MW-11], and 12 [converted to MW-12]) were
installed in and around the free-phase product ground water plume in the area of former Tank Farm A.
The soil borings were drilled to a depth of 10 to 20 feet bgs (Ref. 31, pp. 3-7, 3-8, Figure 3-2). Splitspoon
samples were collected continuously until the water table was encountered. Two soil samples from each
boring were collected and analyzed for PP VOA+15, PP BNA, lead, chromium, and barium. Samples
were collected at 0 to 2 feet bgs and at the water table interface (Ref. 31, p. 3-8).

Phase II RI

Screening techniques were employed in the area of Source 1 to evaluate the presence or absence of
sources, to identify hot spots, and to provide additional data concerning the subsurface from lune 1993
and October 1993, during a Phase II RI for the Lucas plant. Soil borings were drilled in the free-phase
areas near Buildings 50 and 67 and Tank Farm A and soil samples were collected at various depths (Ref.
31, pp. 3-3, 3-14, 3-15).

Phase III RI

During Phase III of the RI, from luly 1995 through August 1995, soil samples were collected from Source
1 and 45 hand-augered borings were located throughout the seep area (seep near Buildings 50 and 67) to
delineate the extent of free-phase product (Ref. 31, pp. 3-3, 3-18).

Analytical results for soil samples collected during the RI from Source 1 indicated the presence of the
following hazardous substances: acetone; 2-butanone; 1,2-dichloroethene; ethylbenzene; 1,1,2,2-
tetrachloroethane; tetrachloroethene; toluene; 1,1,2-trichloroethane; trichloroethene; xylene (total);
benzo(a)anthracene; benzo(a)pyrene; benzo(b)fluoranthene; benzo(k)fluoranthene; chrysene; 2,4-
dimethylphenol; fluoranthene; 2-methylnaphthalene; naphthalene; phenanthrene; pyrene; aluminum;
arsenic; barium; cadmium; chromium; copper; iron; lead; magnesium; mercury; nickel; selenium; silver;
vanadium; and zinc (Ref. 31, Table 4-5, Figure 3-2).

As documented in the RI report, the area of contaminated soil associated with Buildings 50 and 67 is
estimated as 7,000 square feet (Ref. 31, pp. 5-4, 5-5, Figure 3-2). The RI also indicates that the estimated
the volume of contaminated soil in the area of Tank Farm A is 9,000 cubic yards (Ref. 31, p. 5-3).

Provided below is a summary of the analyses for soil samples collected in Source 1 revealing the presence
of contaminated soil in the vicinity of the product seep areas. The sampling locations are shown on Figure
3-2 in Reference 31. Soil samples collected from MW-12 are used to document background
concentrations for shallow soil samples and are used as source samples for deeper soil samples. The soil
in the shallow portion of MW-12 does not contain hazardous substances found in the free-phase product,
Source 1. The free-phase product ground water plume has not contaminated the shallow soil at the
location of MW-12. No other soil sampling location was identified that could be used to establish
background concentrations for shallow soil. All the soil samples are collected from the Westphalia and
Nixonton Urban land complex soil types (Ref. 31, Figure 2-10).

2.4.2.1.3	Volume

During the Phase III activities, free-phase product was measured for the mobile thickness of the product,
the volume of recoverable product, and the recharge rates of the product (Ref. 31, p. 3-20). A bail-down
test was conducted to identify the thickness of the product (Ref. 31, Appendix K, Tables El through E4).
The bail-down test completed in WP-3 in the area of the Building 50 indicated that the thickness of the
product in July 1995 as 0.33 foot and in August 1995 as 0.48 foot (Ref. 31, Figures 4-11 and 4-12). The
bail-down test completed in the area of the Building 67 indicated that the thickness of the product in July
1995 at MW-21 as 2.21 feet, at MW-13R as 0.98 foot, and at WP-1 as 1.33 feet (Ref. 31, Figure 4-11). In
August 1995 the thickness of product was recorded at MW-21 as 0.66 foot, at MW-13R as 1.28 feet, and
at WP-1 as 1.33 feet (Ref. 31, Figure 4-12). The bail-down test completed in MW-11 in the area of the
Tank Farm A identified the thickness of product as 1.47 feet in July 1995 and 0.45 foot in August 1995
(Ref. 31, Appendix K, Table E2, and Figures 4-11 and 4-12). The lateral extent of three separate product
plumes in ground water are shown on Figures 4-11 and 4-12, Appendix K, Reference 31. The plumes are
considered separate because of the absence of product in the monitoring wells located between the plumes
(Ref. 31, p. 4-20). The total volume of the free-phase product cannot be estimated.

2.2 SOURCE CHARACTERIZATION
2.2.1 SOURCE IDENTIFICATION
Name of source: Areas of Contaminated Soil
Number of source: 2
Source Type: Contaminated Soil

This source includes three areas of contaminated soil. The areas of contaminated soil are combined as one
source because they are of the same type, from the same operations, near each other, potentially from the
same releases, contain the same type of contaminants, and were investigated as one source during an RI, as
documented in the sections below.

Contaminated Soil: Pump House

The pump house transferred wastewater from the Lucas plant operations to the lagoon area (Ref. 31, p. 5-
6). Lead contamination has been identified in the soil surrounding the former pump house (Ref. 31, pp.
ES-2, 6-4).

In 1994, NJDEP advanced augers into the bank of Hilliards Creek adjacent to the pump house.
Approximately 1 foot of paint sludge was observed when the augers were retrieved. The sludge tapered to
a faint greenish color about 15 feet downstream of the pump house (Ref. 66, pp. 1,2).

In 1999, a waste sample was collected adjacent to the pump house and was found to contain barium
(14,400 parts per million [ppm]), lead (1,090 ppm), magnesium (7,340 ppm), and mercury (17.8 ppm)
(Ref. 26, pp. 5, 8). An RI confirmed that lead-contaminated soil was associated with the pump house (Ref.
31, pp. ES-2, 3-27, 5-7, and 5-8).

Contaminated Soil: Northwest of Building 55

The RI for the Lucas plant identified contaminated soil northwest of Building 55, in the area of soil boring
B-76 (Ref. 31, p. 5-5, Table 4-11, Figure 3-2). The contaminated soil may have resulted from operations
in former Buildings 15 and 49, formerly located west of the Tank Farm A. Building 15 was used to store
varnish in 440-, 960-, and 2,200-gallon ASTs. Building 49 was used to store varnish in 2,500- and 6,000-
gallon tanks (Refs. 5; 60, p. 33). Soil may have become contaminated during transfer and temporary
storage of materials near the tanks, which may have resulted in leaks and spills (Ref. 59, Appendix II, p.
1155).

Other sources of the soil contamination are shown on an insurance map, dated April 16, 1964, including a
solvent pump house formerly located northwest of Building 55 and leaks from raw materials stored in
Building 55 (Refs. 5; 60, pp. 99, 100).

SD - Characterization and Containment

Source No.: 2

Contaminated Soil: Southeast Corned of Building 55

A soil boring (TB-06) was completed at the southeast corner of Building 55. Analytical results for soil
samples collected from the boring indicated the presence of contaminated soil as documented in Section
2.4.1. The contamination at TB-06 is considered separate from the contaminated soil detected south of
TB-06 in the area of free-phase product ground water plume because the plume does not exceed to
sampling location TB-06 (Ref. 31, pp. 4-11 and 4-12).

Location of the source, with reference to a map of the site: The areas of contaminated soil are located
on the northwest side of Building 55 in the area of test boring 76 (TB-76), on the southeast corner of
Building 55, and in the area of the pump house located west of Building 67 (Ref. 31, Figures 2-2 and 3-2).
The locations where soil sample analyses revealed the presence of contaminated soil and defined the area
of Source 2 are shown on Figure 3-2 of Reference 31.

Containment:

Release to ground water: As documented in the section above, Source 2 is an area of contaminated soil.
No liners, covers, or other containment features are associated with the source; therefore, a containment
factor value of 10 is assigned to this source. Additionally, as documented in Section 4.2.1.5, there is
evidence that hazardous substances have migrated from the source to ground water (Ref. 1, Table 3-2).

Release via overland migration and/or flood: As documented in the section above, Source 2 is an area
of contaminated soil. No runoff control systems are associated with the source; therefore, a containment
factor value of 10 is assigned to this source. Additionally, as documented in Section 4.1.2.1.1, there is
evidence that hazardous materials have migrated from the source (Ref. 1, Table 4-2).

Gas release to air: The air migration pathway was not scored.

Particulate release to air: The air migration pathway was not scored.

2.4 WASTE CHARACTERISTICS
2.4.1 Hazardous Substances:

The hazardous substances associated with Source 2 were identified during numerous soil sampling
investigations. The most recent investigation was a five-phase RI for the Lucas plant (Ref. 31, p. 3-3).
The data from the RI are used to characterize Source 2. Figure 3-2, in Reference 31, was used to identify
soil sampling locations specifically associated with Source 2. The soil samples were analyzed for Priority
Pollutant Volatile Organic Analysis plus 15-non target compounds (PP VOA+15), Priority Pollutant Base
Neutral Analysis (PP BNA), lead, chromium, and barium (Ref. 31, p. 3-11). During Phase IV of the RI
for the Lucas plant, three soil borings were drilled around the pump house. Sludge and paint were
observed in one of the borings, TB-73. A sample of the sludge and paint was collected from the boring
(Ref. 31, p. 5-7). Additional investigations were conducted in the area of pump house to further delineate
the extent of soil contamination (Ref. 31, pp. 3-26, 3-27). Three soil borings were hand augered in the
area of the pump house (Ref. 31, pp. 3-3, 2-27). The borings were installed to delineate the extent of
sludge and paint chips observed in a boring, TB-73, previously drilled in the area of the pump house (Ref.
31, p. 3-27).

The tables below provide a summary of hazardous substances detected in soil samples collected from
Source 2 during numerous phases of the RI. The result for a background soil sample is listed to provide a
reference concentration for the hazardous substances. Background soil sample selection is based on
whether the background and source soil sample were collected within the same depth range, period of
time, and whether the samples were analyzed for the same hazardous substances. All soil samples
collected from 1990 to 1997 were analyzed by Weston Analytics Division, a New Jersey-certified
laboratory. All samples collected from 1998 to 2000 were analyzed by Severn-Trent Laboratories (STL),
a New Jersey-certified laboratory (Ref. 31, p. 3-37). Reference 111 provides a Quality Assurance Project
Plan used by Sherwin-Williams' environmental consultant. The plan provides analytical methods,
quantitation limits, and detection limits for some of the investigations conducted by Sherwin-Williams'
(Ref. 111). It is likely that these same methods were used for analyzing the samples summarized in this
section. Analytical data sheets from the laboratories are not available; however, the RI report that
Sherwin-Williams prepared indicates that the analytical data are valid. The analytical results in the tables
below are considered usable and of known quality (Ref. 31, p. 3-38). Table 3-1 of Reference 31 provides
a summary of the analytical suite for the soil samples.

The locations of the soil samples are provided on Figure 3-2, in Reference 31, and are circled.
Contaminated soil southeast corner of Building 55:

Analytical results for a soil boring sample collected from the southeast corner of Building 55 indicated the
presence of a number hazardous substances three times above the background concentrations. The soil
sample does not contain the same hazardous substances as detected in the product samples and is therefore,
considered a separate area of contamination, as documented below.

difficult to document because numerous areas within the area are covered with buildings, parking lots, and
roads. Numerous removal actions have been conducted in the area of Source 2; however, based on Section
2.4.1 for Source 2, contamination still remains in Source 2 (Refs. 18, pp. ES-1, 1-1, 1-2, 3-5, 4-1; 31, pp.

SOURCE DESCRIPTION
2.2 SOURCE CHARACTERIZATION
Source Number: 3
Source Description: Lagoons
Source Type: Backfilled surface impoundment

Source 3 includes five backfilled surface impoundments and an associated pipeline and drainage channel.
Between 1950 and 1977, wastewater generated from the paint manufacturing process was discharged into
five impoundments for treatment and disposal. The lagoons were located south of the facility.
Wastewater was discharged by gravity from the manufacturing plant to a lift station and subsequently
pumped to a 27,000-gallon concrete holding basin. Alum was added to the wastewater, and then the
wastewater was fed by gravity from the basin to Lagoon 1 for coagulation and settling. The wastewater
was then transferred to Lagoons 2, 3, and 4 for biological treatment. A holding basin was also used in the
wastewater treatment system (Refs. 6, pp. 2-3, 2-4, and Figure 2-4; 31, p. 2-5). Tank washout from the
latex system and Sher-dye was disposed of in the lagoons (the sanitary waste system on Lucas plant) (Ref.
70, pp.9, 11).

Aerial photographs from 1940 show two open storage areas along a railroad spur. This area appears to be
the location of the lagoons (Ref. 7, pp. 4, 5). Aerial photographs from 1951 show three impoundments in
the area of the lagoons. An open storage area is located north of the lagoons (Ref. 7, pp. 6, 7, 10, 11). The
1961 aerial photographs indicate that one of the three lagoons (impoundments) was divided into four
separate lagoons, for a total of six lagoons. Several piles of light-toned mounded material were observed
near one of the lagoons (impoundment one) (Ref. 7, p. 8). Aerial photographs from 1973 show the
presence of a pipeline extending from the north bank of one of the lagoons (impoundment one) to a
drainage channel (Hilliards Creek) that runs through the center of the Lucas plant. An outfall from the
western bank of the lagoon area toward a drainage channel (Hilliards Creek) is visible (Ref. 7, pp. 10, 11).
Aerial photographs from 1975 show the presence of leachate scars on the downslope of one of the lagoons.
The lagoons are no longer visible in 1984 aerial photographs (Ref. 7, p. 13).

In 1975, one of the settling lagoons overflowed into Hilliards Creek (Ref. 59, Appendix X, p. X6).

On July 31, 1975, and September 16, 1975, NJDEP inspectors noted foul solvents odors emanating from
monitoring wells in the area of the lagoons, and one of the lagoons was observed to be leaking its contents
into Hilliards Creek (Ref. 32, p. 3).

On May 5, 1976, NJDEP inspectors observed that a feed pipe used for transport of raw materials in the
facility had ruptured causing an oil discharge to the primary settling lagoon and Hilliards Creek (Ref. 32,
p. 3).

Source No.: 3

In 1976, NJDEP directed Sherwin-Williams to conduct a subsurface investigation in the former lagoon
area (AEC IV) (Ref. 31, pp. 3-1, 3-33). Approximate depths (from an average existing ground surface)
were as follows:

Lagoon 1 = 5 feet
Lagoon 2=15 feet
Lagoon 3 = 8 feet
Lagoon 4 = 12 feet
Holding Basin =10 feet

Depths are documented in Reference 31 (pp. 3-33, 3-34). According to the RI report, a sludge pit was
located in the area of the lagoons. The depth of the sludge pit was 20 feet (Ref. 31, pp. 3-33, 3-34).
Sludge was encountered at the base of the lagoons at depths of 2 to 5 feet in the lagoons and the base of
the holding basin at a depth of 3 feet. Twenty-eight soil borings were drilled in the lagoon area (Ref. 31,
p. 3-34). A review of Figure 2-4 in Reference 6 indicates that the four impoundments, aholding basin (the
fifth surface impoundment), and a sludge disposal area were associated with the four surface
impoundments. The sludge pit, as referred to in the RI, may be the sludge disposal area shown on Figure
2-4 in Reference 6.

On August 17, 1978, NJDEP issued an administrative order to Sherwin-Williams to remove sludge in the
area of the lagoons and to monitor ground water. The order was based on findings that Sherwin-Williams
operated unlined wastewater treatment lagoons and stored sludge without NJDEP approval or
authorization. NJDEP concluded that the lagoons allowed inadequately treated wastewater to percolate
into the ground water (Ref. 57, pp. 1, 2, 3).

In 1979, a subsurface investigation was conducted in the area of the lagoons, or Site 2 as referenced in
reference documentation (Ref. 41, Plates 2, 6, and 7, p. 10). The report documenting the investigation
indicated that the lagoon area included the following: a holding pond (150 by 180 feet), ponds 1 and 2 (60
by 80 feet each), pond 3 (40 by 40 feet), and pond 4 (100 by 150 feet). (A sludge disposal pond, 40 by
150 feet, was also located adjacent to the lagoons. However, its waste (dried sludge) was included in
another NPL site, the US Avenue Burn site and not included in the waste quantity for this site [Ref. 41, pp.
10, 14, Plate 6].) According to the report, industrial waste including paint sludge and raw sewage was
emptied into the holding pond, where primary sedimentation took place. A pump suctioned material from
the holding pond to pond 1. From pond 1, the fluid was transferred by gravity to pond 2, then to pond 3,
and finally to pond 4. Dried sludge was excavated from ponds 1, 2, 3, and 4 then disposed of in the sludge
holding pond. The report does not identify the location where pond 4 discharges (Refs. 41, p 11; 8, p. 3).
Analytical results for soil borings indicated the presence of dried paint in the holding pond, ponds 1, 2, 3,
and 4, and in the sludge disposal pond. (The waste quantity associated with the sludge disposal pond is
evaluated as part of a separate site, US Avenue Burn Site.) Drainage from the lagoon area was noted to be
toward the west, the location of Hilliards Creek (Refs. 41, p. 14; 9).

In 1979, a total of 8,096 cubic yards of sludge was removed from the lagoon area. After the sludge was
visibly removed, the lagoons were filled in with clean fill. The removal was considered complete when all
the visually identifiable sludge and contaminated soils were removed (Refs. 31, pp. 3-33 and 3-34; 42, p.
4). Since the removal action was based on visually removing the waste associated with Source 3, it cannot
be documented that all the contamination associated with Source 3 has been removed. No confirmatory
samples were collected. Available data, provided in Section 4.0 of this documentation record, indicate that

62


-------
SD - Characterization and Containment

Source No.: 3

Source 3 released hazardous substances to ground water and surface water. The contamination associated
with the releases to ground water and surface water has not been addressed. Since no confirmatory
samples were collected to document that all contamination associated with Source 3 was removed and
releases to ground water and surface water from Source 3 have not been addressed, the removal action
completed in the Source 3 is not considered a qualifying removal action (Refs. 82; 83).

In 1993, a site inspection (SI) report completed by NJDEP indicated that memorandums by Sherwin-
Williams described a breach of the lagoon system (Ref. 59, p. 3).

Location of the source, with reference to a map of the site: Figure 2-4, in Reference 6, shows the
location of the four backfilled surface impoundments (also referred to as lagoons and ponds in reference
documentation) and the holding basin, fifth backfilled surface impoundment. Source 3 is located on the
southeastern portion of the former Lucas plant, on the south side of Foster Avenue and on the east side of
Hilliards Creek (see Figure 2-4 in Reference 6).

Containment:

Release to ground water: The lagoons were unlined (Ref. 57, pp. 1, 2, 3); therefore, a containment factor
value of 10 is assigned to this source. Additionally, as documented in the section above, there is evidence
that hazardous substances migrated from the source (Ref. 1, Table 3-2).

Release via overland migration and/or flood: Migration of hazardous substances from the source area
has been documented; therefore, a containment factor value of 10 is assigned to this source (Ref. 59,
Appendix X, p. X6). Additionally, as documented in the section above, no surface water runoff control
system was associated with Source 3 (Ref. 1, Table 4-2).

Gas release to air: The air migration pathway was not scored.

Particulate release to air: The air migration pathway was not scored.

2.4 WASTE CHARACTERISTICS
2.4.1 Hazardous Substances:

In 1977, wastewater sludge samples were analyzed for disposal purposes. The leachate analysis revealed
the presence of lead, 0.16 mg/L (Ref. 19, pp. 1, 3). The paint sludge was classified as special waste (Refs.
23; 24). In 1977, analysis of spent iron residue from the wastewater treatment plant revealed 0.007 mg/L
of arsenic and 0.25 mg/L of lead in the leachate (Ref. 22, pp. 1, 2). In 1978, analysis of a paint sludge
sample revealed 0.08 percent by weight of lead (Ref. 20, pp. 1, 2). In April 1978, analysis of a wastewater
sludge sample revealed the presence of arsenic at 0.7 mg/kg (Ref. 25, pp. 1, 2). In March 1978, analysis of
leachate from paint sludge revealed 0.015 mg/L of lead (Ref. 21, p. 1).

Soil samples were collected from the approximate center of each lagoon (referred to as ponds in reference
documentation) (Ref. 31, p. 3-36) in November 1996, during Phase IV of the RI for the Lucas plant (Ref.
31, p. 3-3). Analysis of a soil sample collected from the lagoons revealed the presence of 11 mg/kg of
pentachlorophenol, 4.5 mg/kg of arsenic, and 0.08 mg/kg of mercury (Ref. 31, Table 4-7 [p. 2], Figure 3-
2). The Table 2 summarizes the hazardous substances detected in soil boring samples collected from the
lagoons during Phase IV of the RI for the Lucas plant. The soil samples were collected during the RI to
confirm whether the 1979 remediation was effective. One sample was collected from the approximate
center or each lagoon and the disposal area. Samples SS-P1, SS-P2, SS-P3, and SS-P4 were collected
from the former lagoons. Sample SS-HP was collected from the former holding pond. The samples were
collected immediately below the base of the former features or the fill material to evaluate whether natural
soils were contaminated by the operations of the lagoons and ponds (Ref. 31, p. 3-36). No appropriate
background soil sample was identified for comparison to results for soil samples collected from the
lagoons.

All soil samples collected during the RI from 1990 to 1997 were analyzed by Weston Analytics Division,
a New Jersey-certified laboratory. All samples collected from 1998 to 2000 were analyzed by STL, a New
Jersey-certified laboratory (Ref. 31, p. 3-37). The analytical results in the tables below are considered
usable and of known quality (Ref. 31, p. 3-38). Table 3-1 of Reference 31 provides a summary of the
analytical suite for the soil samples. The detection limits were not provided in the RI report.

2.4.2.1.3	Volume

In 1979, a total of 8,096 cubic yards of sludge was removed from the lagoon area. After the sludge was
visibly removed, the lagoons were filled with clean fill. The removal was considered complete when all
the visually identifiable sludge and contaminated soils were removed (Refs. 31, p. 3-34; 42, p. 4).
Analytical results for soil samples collected during a latter investigation, after the removal, indicate that
residual contamination remains in the soil underlying the lagoons. The hazardous waste quantity
associated with the lagoon area cannot be quantified.

2.4.2.1.4	Area

In 1979, a subsurface investigation was conducted in the area of the lagoons, or Site 2 as referenced in
reference documentation (Ref. 41, Plates 2, 6, and 7, p. 10). The report documenting the investigation
indicated that the lagoon area included the following: a holding pond (150 by 180 feet), ponds 1 and 2
(60 by 80 feet each), pond 3 (40 by 40 feet), and pond 4 (100 by 150 feet). (The sludge disposal pond, 40
by 150 feet, was also identified, but the waste quantity associated with that source was evaluated as part
of a separate site, the US Avenue Burn site [Ref. 41, pp. 10, 14, Plate 6].) The area associated with the
lagoon area is estimated to be 26,200 sq ft to 32,200 sq ft. Since the Source 3 area cannot be adequately
confirmed, the area of Source 3 is assigned the value of greater than 0.

SOURCE DESCRIPTION
2.2 SOURCE CHARACTERIZATION
Source Number: 4

Source Description: Contaminated Soil Associated with Tank Farm B
Source Type: Contaminated Soil

Source 4 is an area of contaminated soil identified through sampling in the area of Tank Farm B (Refs. 31,
Table 4-3, Figure 3-2; 59, Appendix II, pp. 1131, 1132). The presence of contaminated soil in the area of
Tank Farm B, as documented in Section 2.4.1, indicates that product leaked and spilled from the tank
farm. Tank Farm B is located in the southern section of the plant on the south side of Foster Avenue and
on the west bank of Hilliards Creek (See Reference 6, Figure 2-4). Raw materials were stored in ASTs
and USTs in the area of Tank Farm B. Seventeen tanks were associated with Tank Farm B (Refs. 31,
Table 2-2; 6, Figure 2-4). Materials stored in the tanks included isobutyl alcohol, C.P. acetone, methyl
amyl acetate, isopropyl acetate, xylene, lacquer solvent, toluene, toluene-based solvent blend, methyl ethyl
ketone, ethyl acetate, isopropanol, solvent, methyl isobutyl ketone, solvent blend, and aromatic naphtha
(Refs. 5; 31, Table 2-2).

All ASTs and USTs were dismantled and removed from the property in June 1981, after the Lucas plant
was sold to Scarborough (Ref. 31, p. 2-4).

The soil sample analytical data generated from an RI in the area of Tank Farm B revealed the presence of
numerous hazardous substances in the area of Tank Farm B, including: acetone; 2-butanone; 2-hexanone;
chloroform; ethylbenzene; toluene; 1,1,1-trichloroethane; trichloroethene; xylenes; benzo(a)anthracene;
benzo(a)pyrene; benzo(b)fluoranthene; benzo(k)fluoranthene; chrysene; di-n-butyl phthalate;
fluoranthene; phenanthrene; pyrene; aluminum; antimony; arsenic; barium; chromium; cobalt; lead;
magnesium; mercury; zinc; and cyanide (Refs. 31, Table 4-3, Figure 3-2; 59, Appendix II, pp. 1131,1132).

Location of the source, with reference to a map of the site: As shown on Figure 2-4, in Reference 6,
Tank Farm B was located on the west side of Hilliards Creek and on the south side of Foster Avenue, just
west of Building 50 (Refs. 6, Figure 2-4; 31, Figure 3-2).

Source No.: 4

Containment:

Release to ground water: As documented in the section above, Source 4 is an area of contaminated soil.
No containment structures are associated with the source; therefore, a containment factor value of 10 is
assigned to this source (Ref. 1, Table 3-2).

Release via overland migration and/or flood: As documented in the section above, Source 4 is an area
of contaminated soil. No containment structures are associated with the source; therefore, a containment
factor value of 10 is assigned to this source (Ref. 1, Table 4-2).

Gas release to air: The air migration pathway was not scored.

Particulate release to air: The air migration pathway was not scored.

2.4 WASTE CHARACTERISTICS
2.4.1 Hazardous Substances:

Liquid hazardous substances were stored in the tanks in the area of Tank Farm B. The contents of the
tanks are summarized in Table 2-2 of Reference 31. The presence of contaminated soil in the area of Tank
Farm B, as documented below, indicates that product leaked and spilled from the tank farm.

Four soil borings (TB-5, MW-16, MW-17, and MW-18) were installed in the vicinity of former Tank
Farm B (Ref. 31, pp. 3-1, 3-31) from August 1991 through January 1992, during Phase I of the RI (Ref.
31, p. 3-3). The soil samples were analyzed for PP VOA+15, PP BNA, lead, barium, and chromium (Ref.
31, p. 3-31).

Additional soil borings (TB-91 through TB-93) were installed to delineate the extent of subsurface xylene
contamination in the area from July 1998 through January 2000, during Phase V of the RI (Ref. 31, pp. 3-
3, 3-33). Two samples were collected from each boring and sent for analysis of VOCs (Ref. 31, p. 3-33).
A summary of soil samples collected from Source 4 during two phases of the RI is provided in the tables
below. The result for a background soil sample is listed when available to provide a reference
concentration for the hazardous substances. Background soil samples were selected based on whether the
background and source soil sample were collected within the same depth range and same period of time
and whether the samples were analyzed for the same hazardous substances. All soil samples collected
from 1990 to 1997 were analyzed by Weston Analytics Division, a New Jersey-certified laboratory. All
samples collected from 1998 to 2000 were analyzed by STL, a New Jersey-certified laboratory (Ref. 31, p.
3-37). The analytical results in the tables below are considered usable and of known quality (Ref. 31, p. 3-
38). Table 3-1 of Reference 31 provides a summary of the analytical suite for the soil samples. No
background soil samples could be identified for the source soil samples collected in 1993 and 1996.

Soil boring samples collected from MW-14 are used as background sampling locations for shallow soil
intervals. The deeper soil intervals in MW-14 is contaminated with hazardous substances associated with
the free-phase product ground water plume in the area of Buildings 55 and 67 as documented in Section
2.4.1 for Source 1.

side of Gibbsboro-Clementon Road; (7) soil underlying the 22,000-gallon fuel oil tank, former coal
storage bin, latex storage tanks, and drum storage area formerly located on the north side of Foster Avenue
in the areas of former Buildings 37 and 52; (8) soil underlying Building 52, used for mixing lacquers, and
Building 53, used for storing laquer and filling cans with solvent; (9) soil underlying the former railroad
that ran from Foster Avenue, north to numerous locations on the former Lucas plant; (10) soil underlying
former Building 39 where paint products were stored and mixed; (11) soil underlying Buildings 7-1,7-2,
29, and 58, which were used to store cans of paint and finished stock (Refs. 4; 5; 60, pp. 66, 67, 68, 96).
Sampling investigations of many of these potential source areas have not been conducted.

Aerial photographs from 1961 show two open storage areas in the northeastern corner of the Lucas plant
(Ref. 7, p. 8). This area is referred to as the vacant lot in RI documents.

The 1984 aerial photographs show drums stacked around buildings in the northern portion of the Lucas

82


-------
plant and open storage areas in the north and central portions of the plant (Ref. 7, p. 13).

Lacquer storage tanks were located at an unidentified location on the Lucas plant, and the soil underlying
the tanks may be contaminated (Ref. 13, p. 7).

Septic systems located on the plant are also potential sources of soil contamination (Ref. 31, pp. 3-17, 4-
28, 4-29, 4-30, Table 4-21, Figure 3-2).

Surface runoff from the northern section of the former Lucas plant flowed to Silver Lake. The bottom
sediments of Silver Lake were periodically excavated to maintain the volume of water in the lake for water
power and purity. The sediments were removed from the plant area and spread on nearby fields (Ref. 60,
pp. 56, 57). Since potential areas of soil contamination were located on the northern section of the plant,
as evidenced by historical maps, the sediments in Silver Lake may have been contaminated and may have
contaminated nearby fields (Refs. 4; 5).

Gasoline Station

A gasoline station is located on the northeastern section of the former Lucas plant. Free-phase product
was observed in the area of the former gasoline station. Analytical results for a product sample indicated
benzene, ethylbenzene, xylene, naphthalene, and 2-methyl naphthalene (Ref. 31, pp. ES-6, 3-30).

Twelve soil samples (TB-39 through TB-48, TB-52, and TB-53) were collected from the area of the
former gasoline station from July 1995 through August 1995, during Phase III of the RI for the Lucas
plant (Ref. 31, pp. 3-3, 3-18). The soil samples were collected within the vadose zone and were biased
toward intervals that exhibited elevated field screening results (Ref. 31, p. 3-18). Analytical for soil
samples collected during the RI did not identify a significant area of soil contamination in the area of the
gasoline station; however, ground water contamination in the area was identified (Ref. 31, Table 4-11,
Figure 3-2).

Test pits were excavated on the gasoline station property to identify the USTs and the waste oil pit
reportedly located on the property on July 11 and 12, 1995, during Phase III of the RI for the Lucas plant.
Two steel USTs were located and uncovered. The tanks were observed to be corroded, and holes were
visible in the tanks. The waste oil pit was not uncovered during the excavation (Ref. 31, p. 3-21).

The plume identified in the area of gas station was determined to be limited to a small area on the
northwest side of the former gas station building and to be separate from the plumes identified in the areas
of Buildings 50 and 67 and former Tank Farm A (Ref. 31, Figures 4-11 and 4-12).

Lead-Contaminated Soil Surrounding Hilliards Creek

Soil samples were collected from 16 transects set across Hilliards Creek between Clementon-Gibbsboro
Road and Hilliard Road (T1 through T15 and T17) (Ref. 51, pp. 5, 8) between December 1999 and
January 2000. As shown on Reference 97, Hilliards Creek is located downgradient of the former Lucas
plant and received surface water runoff from the plant during and before its operation (see Reference 6,

83


-------
Figure 2-4 and Reference 31, Figure 3-2) (Ref. 31, pp. 2-9, 2-17). The soil samples were collected to
evaluate whether periodic flooding transported contaminated sediments from Hilliards Creek to the flood
plain of Hilliards Creek. A soil sample was collected from the north and south banks of Hilliards Creek at
each transect location. The transects were spaced 200 feet apart. Soil samples were collected at 30-foot
intervals along each transect. The soil samples collected from the banks of Hilliards Creek were collected
from within the 100-year flood plain. Additional soil samples were collected as needed to complete the
horizontal and vertical delineation of lead contamination, and four soil boring samples were collected from
the southern berm of the manmade pond located off Gibbsboro-Clementon Road (Ref. 51, pp. 5, 8).

All samples were analyzed for lead (Ref. 51, p. 5). Approximately 25 percent of all samples were
analyzed for TAL metals plus cyanide, 5 percent for TCLP metals (including copper and zinc), 5 percent
for TCLP VOCs and BNA analyses (Ref. 51, p. 6). All samples were collected in accordance with the
November 1999 work plan for the Hilliard's Creek Site, Gibbsboro, New Jersey, and the December 1999
work plan addendum (Refs. 51, p. 4; 68; 69). The results from the analysis of the soil samples were
validated according to Region II Contract Laboratory Program (CLP) data validation protocols (Ref. 51, p.
20). The analytical laboratory used CLP statement of work (SOW) ILM04.0 for the analysis of lead and
TAL metals (Ref. 68, Table 2).

No background soil sample was collected. However, a transect (T17) was placed across Nicholson
Branch, a tributary of Hilliards Creek. The transect was used to collect surface and subsurface soil from
the two banks of Nicholson Branch (Ref. 51, pp. 5, 8, and Figure 4). The samples collected from transect
17 are used to establish background levels for lead in soil located within the Hilliards Creek flood plain.
Analytical results for soil samples indicating concentrations of lead above three times the background
concentration are provided in the Tables 3 and 4. The background soil samples were analyzed for lead
only. Therefore, lead is the only metal evaluated. As documented in Tables 3 and 4, analytical results for
soil samples collected from the banks or flood plains of Hilliards Creek indicated the presence of lead-
contaminated soil.

Source Summary

Lead-Contaminated Soil at 165 Kirkwood Road

Analytical results for soil samples collected as part of the ACO indicated the presence of lead in surface
and subsurface (1 to 6.5 feet bgs) soil on a residential property at 165 Kirkwood Road (Refs. 50, p. 1-2;
51, Appendix A). In April 2000, composite samples were collected from 165 Kirkwood Roadand
analyzed for TCLP metals, VOCs, and SVOCs (Refs. 30, p. 1; 51, Table 1, pp. 24, 25, Appendix A). The
leachate from the samples contained arsenic (up to 1,190 (ig/L). barium (up to 1,740 (ig/L). cadmium (up
to 42.3 (ig/L). chromium (up to 59.1 (ig/L). and lead (up to 53,000 (ig/L) (Ref. 30, pp. 16, 18, 20, 22, 24,
26, 28, 30, 99, 101, 103, 105, 107, 119, 121, 123, 125, 127, 135, 137 through 149, 181, 182, 183, 185,
186, 188, 190, 191, 192, 194, 195, 196). No VOCs or SVOCs were detected in the samples. Analytical
results for soil samples indicated high concentrations of lead in surface and subsurface soil (1.0 to 6.5 feet
bgs) (Ref. 51, Table 4 and Appendix A).

Also in April 2000, soil samples were collected from 165 Kirkwood Road to complete the delineation of
lead-contaminated soil (Ref. 51, p. 6). The property was divided into grids representing no more than 20
cubic yards each. Four borings were completed in each of these grids and samples were collected at
intervals of 0 to 6 inches, 12 to 18 inches, and 24 to 30 inches. The four samples from each interval were
composited on an equal-weight basis and analyzed for total lead. In total, 413 soil samples were collected
during the April 2000 sampling event. The results of the April 2000 investigation indicated that lead was
present at 165 Kirkwood Road at levels ranging from non-detectto 38,800 mg/kg (Ref. 51, p. 7 and Table
4). The address 165 Kirkwood Road is located on the flood plain of Hilliards Creek (Ref. 51, Table 4-b).
Hilliards Creek bisects the backyard the property (Ref. 50, p. 1-2). Lead-contaminated soil at this location
may be caused by releases from the Lucas plant to Hilliards Creek and the subsequent flooding of 165
Kirkwood Road by Hilliards Creek.

In September and November 2001, surface and subsurface soil samples were collected at 165 Kirkwood
Road to complete delineation of lead contamination identified during earlier sampling events. Soil borings
were drilled up to 10 feet bgs. Subsurface soil samples were collected at 1-foot intervals ranging from 0 to
10 feet bgs. The uppermost 6 inches of each interval were collected for analysis (Ref. 51, pp. 13, 14, 19,
23). In October 2003, an interim removal action was completed at 165 Kirkwood Road: the top 6 inches
of soil were excavated from the property and disposed of (Ref. 50, pp. ES-1, 2-3). Lead-contaminated soil
may remain on the property (Ref. 51, Table 4 and Appendix A) since only the top 6 inches of soil were
removed from the property and results for soil samples below this depth indicated concentrations of lead
greater than 400 mg/kg.

4.1.1 GENERAL CONSIDERATIONS

4.1.1.1 DEFINITION OF HAZARDOUS SUBSTANCE MIGRATION PATH FOR
OVERLAND/FLOOD COMPONENT

Surface water runoff from the northernmost portion of the Lucas plant discharges directly into Silver Lake
(Ref. 31, p. 2-9). Silver Lake discharges into Hilliards Creek through an underground culvert that crosses
under the parking lot located between the lake and Foster Avenue (Refs. 6, Figure 2-4; 31, p. 2-17). The
north-central portion of the Lucas plant, including portions of Source 2 (contaminated soil northwest and
southeast of Building 55) and the entire area of Source 4, is occupied by buildings andpaved areas. Runoff
generated in the area between Silver Lake and Foster Avenue enters a network of catch basins and storm
sewers, which discharge into Hilliards Creek, immediately south of Foster Avenue (Ref. 31, p. 2-9). From
this point, Hilliards Creek continues to flow in the southwest direction, past Buildings 50 and 67 and the
locations of the surface water impoundments (Source 3), approximately 1,000 feet to Gibbsboro-Clementon
Road, under Gibbsboro-Clementon Road, then past a residential pond located on the north bank of Hilliards
Creek. Hilliards Creek continues in the southwesterly direction and converges with an unnamed tributary
of Bridgewood Lake approximately 800 feet west of Gibbsboro-Clementon Road. The creek continues
approximately 0.85 mile to Kirkwood Lake (Refs. 31, Figures 2-2, 2-4, and 3-2; and 9). Kirkwood Lake
continues in the westerly direction for approximately 4,224 feet to empty into the Cooper River. Cooper
River continues in the northwest direction to complete the 15-mile downstream target distance limit (TDL).
The TDL is documented on Reference 98. Surface features, such as buildings, are shown in Reference 31,
Figures 2-2, 2-4, and 3-2.

Surface water runoff from the southern portion of the Lucas plant, including portions of Source 2
(contaminated soil associated with the pump house) and Sources 1 and 3 flow to Hilliards Creek (Ref. 31,
Figures 2-4 and 3-2, p. 2-9). Free-phase product, Source 1, has been observed entering Hilliards Creek at
the point where the storm sewer north of Building 67 discharges into Hilliards Creek (Refs. 31, Figure 3-2;
18, pp. 2-2, 2-3, Figure 3-1; 48, p. 2-3, Figures 2-1 and 2-4). Aerial photographs from 1973 show the
presence of a pipeline extending from the north bank of one of the surface impoundments (impoundment one)
associated with Source 3 to a drainage channel (Hilliards Creek) that runs through the center of the Lucas
plant. An outfall also was observed extending from the western bank of the impoundment area toward the
drainage channel (Hilliards Creek) (Ref. 7, p. 10).

Historically, surface water runoff from the Lucas plant followed the contours of the land and entered a storm
sewer system that discharged into Hilliards Creek (Refs. 6, Figure 2-4; 18, pp. 2-2, 2-3, 3-2; 31, p. 2-9; 73,
pp. 2, 4). The 1981 United States Geological Survey (USGS) topographic map of Clementon, New Jersey
does not show Hilliards Creek from Foster Avenue to Gibbsboro-Clementon Road (Ref. 9). Observations
made by personnel studying the Sherwin-Williams/Hilliards Creek area indicate that the creek is perennial
in this section (Ref. 80). Therefore, the probable point of entry (PPE) into surface water, Hilliards Creek,
is the point at which the storm sewer empties into Hilliards Creek because free-phase product (Source 1)
contained in the storm sewer has been observed to discharge into Hilliards Creek. Free-phase product has
been observed discharging into the sewer and then entering the creek at this point. This is the location where
the storm sewer north of Building 67 discharges into the creek at sampling location SGW-292 (Refs. 31,

Figure 2-3; 10, pp. 1, 2; 31, p. 3-3; 32, p. 5; 36; 37; 48, p. 2-3; 65, pp. 1, 2, 3; 72, pp. 2, 4; 73, pp. 2, 4). The
overland flow distance from Source 1 on the Lucas plant property to perennial surface water is zero since
free-phase product (Source 1) was observed discharging directly into Hilliards Creek (Refs. 8, pp. 2-2,2-3,
3-2; 18, pp. 2-2, 2-3, 3-2; 31, p. 2-9; 48, p. 2-3 9;73, pp. 2, 4) (Ref. 31, Figures 2-4 and 3-2). This PPE to
surface water is shown on Reference 97 as PPE-1.

The PPE from Source 2 is at sampling location TB-73 collected adjacent to the pump house and to Hilliards
Creek (Ref. 31, Figure 3-2) and is shown in Reference 97 as PPE-2. The most downstream PPE to surface
water is the point at which Source 3, former impoundments, discharged into Hilliards Creek, as shown on
Reference 7, page. 10. Aerial photographs from 1973 show the presence of a pipeline extending from the
north hank of one of the surface impoundments (impoundment one) associated with Source 3 to a drainage
channel (Hilliards Creek) that runs through the center of the Lucas plant. An outfall also was observed
extending from the western hank of the impoundment area toward the drainage channel (Hilliards Creek)
(Ref. 7, p. 10). The overland flow distance is estimated to be 333 feet as measured along the pipe line shown
on Reference 7, page 11. The PPE for Source 3 is the point at which the drainage ditch discharges into
Hilliards Creek, shown as PPE-3 on Reference 97. The PPE to Hilliards Creek from Source 4 (Former Tank
FarmB) is adjacent to sampling location MW-14 (Ref. 31, Figure 3-2) as shown on Reference 98 as PPE-4.

4.1.1.2 Target Distance Limit

Surface water from PPE-4, the most upstream PPE, flows into Hilliards Creek and travels approximately 1.3
miles west to Kirkwood Lake. Kirkwood Lake continues in a westerly direction for approximately 4,224 feet
then empties into the Cooper River. The Cooper River continues in a northwesterly direction to complete
the 15-mile surface water downstream TDL. The TDL is documented on Reference 98.

Surface water from PPE-3, the most downstream PPE, flows into Hilliards Creek and flows approximately
1.2 miles west to Kirkwood Lake. Kirkwood Lake continues in a westerly direction for approximately 4,224
feet then empties into the Cooper River. The Cooper River continues in a northwesterly direction to
complete the 15-mile surface water downstream TDL. The TDL is documented on Reference 98.

4.1.2.1 LIKELIHOOD OF RELEASE

Numerous investigations have been conducted in Hilliards Creek to determine whether the Lucas plant
released hazardous substances to the creek. Only analytical data from the most recent investigations are used
to document an observed release to surface water from the Lucas plant by chemical analysis. However,
summaries of previous investigations, presented in the attribution section, provide additional documentation
of releases to Hilliards Creek.

4.1.2.1.1 Observed Release

An observed release to Hilliards Creek by both direct observation and chemical analysis is documented in
the sections below.

Direct Observation

The free-phase product (Source 1) in the area of Buildings 50 and 67 was initially identified in 1983 when
a seep of an oily substance was observed in the parking lot between former Buildings 50 and 67 (also known

93


-------
SWOF - Observed Release

as the Academy Paints Building). The seep (Buildings 50 and 67 seep) is the surface expression of the free-
phase product in ground water in the area of Buildings 50 and 67 (Source 1). The seep flowed overland to
a storm water catch basin in the parking lot, through the storm sewer, and then discharged through rip rap
into Hilliards Creek (Refs. 32, p. 5; 65, pp. 1, 2, 3). The seep was observed on many occasions during
construction of the new office complex that now occupies the Lucas plant (Ref. 65, p. 1).

On February 7, 1985, and March 6, 1987, New Jersey Department of Environmental Protection (NJDEP)
personnel collected an aqueous sample of Building 50 and 67 seep (Source 1) while it was discharging into
Hilliards Creek (Ref. 32, pp. 5, 6, 7). The exact location of the sample is not provided in reference
documentation. Analytical results for the seep sample indicated the presence of the following hazardous
substances (Refs. 6, Figure 2-4; 10, pp. 1, 2, 25 to 39; 31, pp. 3-2, 3-3 and Figures 2-2 and 3-2; Ref. 32, pp.
5, 6, 7).

On February 19, 1988, and again on February 25, 1988, NJDEP observed the Building 50 and 67 seep
(Source 1) discharging into Hilliards Creek (Refs. 36; 37).

In 1989, NJDEP submitted a sample of the Building 50 and 67 seep to an analytical laboratory for
comparison to known petroleum and solvent products. Results of the comparison indicated that constituents
in the seep sample were most similar to a mixture of solvents and to 627 solvent (a solvent), Varsol 18 (an
oil), and mineral spirits (a solvent), which were used at the Lucas plant (Refs. 63, pp. 1, 2; 31, Table 2-2).

On April 9, 2002, free-phase product (Source 1) from an on-site free-phase product recovery system was
observed in the storm water drain north of Building 67. The storm drain discharges into Hilliards Creek.
Product was pumped out of the storm water drain, and additional measures were taken to prevent further
releases to the drain and Hilliards Creek (Refs. 48, p. 2-3; 72, pp. 2, 4; 73, pp. 2, 4).

Chemical Analysis - 2004

From December 6 through December 9,2004, Tetra Tech collected sediment and surface water samples from
Hilliards Creek and wetlands adjacent to Hilliards Creek. Background surface water and sediment samples
also were collected from Cooper River, Cedar Lake, and an unnamed tributary of Cedar Lake. Background
wetland sediment samples were collected from Linden Lake (Ref. 84, Table 1, and Figure 2). Tetra Tech
collected the surface water and sediment samples beginning at the sample location closest to the point where
Hilliards Creek discharges into Kirkwood Lake (Ref. 84, p. 5, Figure 1). Surface water samples were
collected before the sediment sample at each sample location by submerging the sample container in the
creek. At each location, T etra T ech collected three 40-milliliter vials pre-preserved with hydrochloric acid
for target compound list (TCL) volatile organic compound (VOC) analysis; four 1-liter amber bottles
preserved with ice for TCL semivolatile organic compounds (SVOC), pesticide, and polychlorinated
biphenyls (PCB) analyses; one 1 -liter polyethylene bottle for hardness analyses; and one 1 -liter polyethylene
bottle for dissolved TAL metals and cyanide analyses. The aqueous samples collected for dissolved TAL
metals analysis were filtered and then preserved with nitric acid to a pH of less than 2 prior to sample
shipment (Ref. 84, p. 14).

Tetra Tech collected grab sediment samples for TCL VOC analysis and placed samples directly in the sample
jars. Water was decanted from sediment samples collected for total organic carbon (TOC), grain size, TAL
metals, TCL SVOC, pesticide, and PCB analysis prior to placing the sample in a sample container. Tetra
Tech used these techniques for the collection of all sediment samples (Ref. 84, p. 14).

The TCL organic samples were packaged and shipped to Ceimic Corporation in Narragansett, Rhode Island
for analysis. The samples collected for dissolved TAL metals analysis were packaged and shipped to
ChemTech Consulting Group (CHEMED) in Mountainside, New Jersey for analysis. All samples were sent
for analysis under the U.S. Environmental Protection Agency (EPA) Contract Laboratory Program (CLP)
Case No. 33650. A summary of the sample analysis and analytical methods is provided in T able 5 (Ref. 84,
p. 14).

Sediment and surface water samples analyzed for TCL and TAL constituents were analyzed under the EPA
CLP (Ref. 84, p. 14). All analytical results were validated in accordance with EPA Region 2 "Evaluation
of Metals Data for the CLP Program," and "CLP Organic Data Review and Preliminary Review" (Refs. 85,
p. 15; 86, Standard Operating Procedure Number HW-2).

The locations of the background and release surface water and sediment samples and concentrations of
hazardous substances detected in the samples are provided in the sections below. As documented in Tables
5, 6, and 10, the background and release samples are considered to be comparable because they were
collected within the same time frame, analyzed using the same methods, are located within the same type of
environment (creek or wetland), and have the same composition (see Tables 7, 8, and 9 for concentrations).

2004 Background Sampling Locations

During the Tetra Tech 2004 investigation of Hilliards Creek, Hilliards Creek background surface water and
sediment samples were collected from locations outside of areas known to be contaminated by lead as
indicated by previous investigations. The background locations were selected based on the similarity of
surface water, drainage area, and wetland and soil type (Ref. 85, p. 8). A summary of the background
sampling locations is provided in Table 6. The background sampling locations are provided in Reference
84, Figure 2.

2004 Background Concentrations:

The concentrations of hazardous substances detected in the background surface water and sediment samples
are provided in the Tables 7, 8, and 9. As shown in Reference 84, Figure 2, two background sediment and
surface water samples were collected from wetlands, two sediment and four surface water samples were
collected from tributaries, and one sediment and one surface water sample were collected from a lake (Ref. 84,
Figure 2). The highest concentrations of arsenic, lead, and SVOCs detected in the background samples are
used to establish the background arsenic, lead, and SVOCs concentrations for the Hilliards Creek and wetland
release samples. The wetland sediment sample used to establish background concentrations for arsenic, lead,
and SVOCs is HC-BSD-2 (Tables 7 and 8; Ref. 1, Table 2-3).

The TOC values are presented in Table 7. The TOC values in background sediment samples can be compared
to release sediment sample TOC values to determine whether the background and release samples have
relatively the same amount of carbon.

2004 Release Sampling Locations

During the Tetra Tech 2004 investigation of Hilliards Creek, surface water and sediment samples were
collected from Hilliards Creek and wetlands of Hilliards Creek downstream of the Lucas plant (Ref. 84, p.
6). As documented in the section below, the samples contained concentrations of arsenic, lead, and SVOCs
at concentrations exceeding three times the background concentration. A summary of the release sampling
locations is provided in the Table 10. The release sampling locations are provided on Reference 97.

2004 Release Concentrations:

The concentrations of hazardous substances detected in sediment and surface water samples document an
observed release Hilliards Creek are summarized in Tables 11 and 12, respectively. The sampling locations
are shown on Reference 97. Concentration of the hazardous substance have a data qualifier of "J," estimated
concentration, because the percent moisture was high (Ref. 86, pp. N-4 and N-5 ).

The highest concentrations of arsenic, lead, and SVOCs detected in the background samples are used to
establish the background arsenic, lead, and SVOCs concentrations for the Hilliards Creek and wetland
release samples. The wetland sediment sample usedto establish background concentrations for arsenic, lead,
and SVOCs is HC-BSD-2. The wetland background concentrations are arsenic 7.2 mg/kg x 3 = 21.6; lead
183 mg/kg x 3 = 549 mg/kg; and bis(2-ethylhexyl)phthalate 850 (xg/kg x 3 = 2,550 (xg/kg (no other SVOCs

were detected in the background sample). The creek sediment sample used to establish background
concentrations for arsenic, lead, and SVOCs is HC-BSD-3. The creek background concentrations are arsenic
6.8 mg/kg x 3 = 20.4; lead 93.2 mg/kg x 3 = 280 mg/kg; and bis(2-ethylhexyl)phthalate 640 (xg/kg x 3 =
1,920 |ig/kg (no other SVOCs were detected in the background sample) (Tables 7 and 8; Ref. 1, Table 2-3).
To document an observed release, the concentration of the hazardous substances must be three times the
background concentration and above the sample quantitation limit (SQL) if detected in the background or
greater than or equal to the SQL if not detected in the background sample (Ref. 1, Table 2-3). The SQL for
the release samples are provided in Reference 88. The TOC values are provided in Tables 11 and 12. The
TOC values can be used to compare release and background sample TOC contents.

Chemical Analysis -1998

InNovember 1998, 676 sediment samples, 42 soil samples, three waste samples, and eight aqueous samples
were collected from Hilliards Creek between Foster Avenue and Hilliards Road and tributaries to Hilliards
Creek to determine the extent of lead contamination within the creek and the creek's flood plain. Samples
were collected from Hilliards Creek every 50 feet upstream from Hilliards Creek Road to Silver Lake,
covering a total distance of approximately 4,600 feet. In total, 92 stream sampling points or 92 transects
were established within Hilliards Creek. Three sets of samples were collected from each of the transects:
one set of samples from the north bank, one set of samples from the south bank, and one set of samples from
the center of the creek. Each set of samples consisted of two composite samples collected at depths of
approximately 0 to 2 inches below ground surface (bgs) and 1 to 1.5 feet bgs. The samples collected from
the center of Hilliards Creek are used to document an observed release to the creek. The sample identifier,
SD, indicates that the sample was collected from the center of the creek. The last two numbers in the sample
identification indicated the depth at which the sample was collected. For example, sample SD-60-0-2,
indicates that the sample was collected at the center of the creek (SD), at transect location number 60, and
at the depth of 0 to 2 inches bgs (Ref. 26, p. 1, Figure 1, Table 1).

Soil samples also were collected on the north and south flood plains of Hilliards Creek at distances of 7 and
12 feet from the north and south bank of Hilliards Creek (Ref. 26, pp. 2, Figures 1 and 2, and Table 1, pp.
4 and 5).

Blue-stained material, believed to be paint, was observed in the sediments of Hilliards Creek and in soil
adjacent to the creek (Ref. 26, Table 1, p. 5).

A sediment sample (N49A-10) collected from Hilliards Creek containing blue-stained material (paint) also
contained arsenic (1,280 mg/kg) and lead (68,000 mg/kg) (Refs. 26, p. 5; 27, p. 9). Three waste samples
collected from the banks of Hilliards Creek contained arsenic up to 759 mg/kg, and lead up to 65,000 mg/kg
(Refs. 26, p. 5; 27, p. 11).

No background sample was collected during the sampling event. A sediment sample was collected from an
unnamed tributary draining Bridgewood Lake, on the west side of Gibbsboro-Clementon Road (Ref. 26,
Figure 1, p. 4). That sample, SD-60, is used to establish background concentrations of lead for the 1998
analytical data collected for Hilliards Creek. The concentrations of arsenic and lead detected in the
background sample, as documented in Table 14, indicate that the sampling location was not impacted by
activities on the Lucas plant. The background and release samples are considered to be comparable because
they were collected within the same time frame, analyzed using the same methods, are located within the
same type of environment (creek), receive drainage from similar areas, collected from the same depths, and
are located within the same drainage basin (Refs. 9; 26).

All samples were analyzed for total lead using EPA Method 6010B (Ref. 28, p. 2). The detection limits are
summarized in Reference 110.

Locations of Release Samples 1998

A summary of the release sampling locations is provided in Table 15. The release sampling locations are
provided on Figure 1 in Reference 26. The sampling locations on Figure 1 in Reference 26 identify each
sampling location by the number used to designate the transect location. The distances measured from Foster
Avenue, Gibbsboro-Clementon Road, and Hilliards Road to the sampling locations provided in Table 15
below are measured from the intersection of Hilliards Creek and the road along the contours of Hilliards
Creek. Rather than straight line distances from the road to the sampling location. The samples were
collected at 50-foot intervals (Ref. 26).

The significant increase in concentrations of lead, arsenic, and SVOCs to Hilliards Creek is clearly
attributable in part to historic and ongoing releases from the activities at the Sherwin-Williams/Hilliards
Creek site. The history of the use of lead, arsenic, and SVOCs at the paint works is well documented.
Although the operations that led to the historic releases most likely terminated by the 1980s, this does not
mean the contamination documented downstream from the paint works area in Hilliards Creek did not at least
in part originate from these operations. Further, at least part of the lead, arsenic, and SVOCs in Hilliards
Creek is entering Hilliards Creek via ground water seeps flowing overland to the creek (perhaps via the
Sherwin-Williams treatment system) or by direct discharge of ground water to the creek.

Besides the historic information linking lead and arsenic to the paint works operations, these substances are
also associated with four sources evaluated at the site. In addition, numerous studies by both EPA and
Sherwin-Williams have shown continuous increased contamination of these substances in Hilliards Creek
downstream of the paint works area and the PPEs for the four site sources.

The 1998 investigation of Hilliards Creek documented the presence of lead in the sediments of Hilliards
Creek from the Lucas plant property to Gibbsboro-Clementon Road and extending to Hilliards Road at
concentrations three times the background amount, which indicated an observed release of lead to Hilliards
Creek. (Lead was the only hazardous substance analyzed for during this investigation.) This includes a
distance of approximately 4,600 feet (Ref. 26, p. 8). A 2004 Hilliards Creek investigation included the
collection of sediment samples from Hilliards Creek between Gibbsboro-Clementon Road and Hilliard Road.
The 2004 investigation documented a significant increase in lead concentrations to Hilliards Creek along this
entire section, Gibbsboro-Clementon Road to Hilliards Road.

The Lucas plant, located at the headwaters of Hilliards Creek, was used to manufacture paints that contained
lead (Refs. 9; 12; 6, Figure 2-4; 61, pp. 3, 4, 5, 6, 8, 12, 19, 22, 26,30). Surface water runoff from the Lucas
plant flowed to Hilliards Creek during the entire operational period ofthe Lucas plant (Refs. 3,4,5; 6, Figure
2-4; 18, pp. 2-2, 2-3, 3-2; 31, p. 2-9; 73, p. 2, 4). The wastewater lagoons (Source 3), used to treatand store
lead-contaminated paint sludge, also discharged to Hilliards Creek (Refs. 7, pp. 10, 11; 8, p. 3; 19, pp. 1,3;
20, pp. 1,2; 21, p. l;25,pp. 1,2; 41, p. 11). Lead was used extensively at the Lucas plant (Refs. 13, p. 3;
31, p. 2-3; 60, pp. 6, 8,10,12,22,26). The presence of lead within Hilliards Creek extending from the Lucas
plant to Hilliards Road indicates that over time, from operations at the Lucas plant, lead has accumulated in
the sediments of Hilliards Creek and its flood plain.

The 2004 Hilliards Creek investigation also documented a significant increase in arsenic concentrations to
Hilliards Creek from Gibbsboro-Clementon Road to Hilliard Road. As documented in source section of this
HRS documentation record, arsenic was detected in source samples at concentrations exceeding three times
background. Arsenic is a common constituent in paint and a constituent of Paris green, a pigment
manufactured at the Lucas plant (Refs. 12; 99, p. 1; 100, p. 1; 101, p. 2). Arsenic is also used in paint for
the bottom of ships as was manufactured at the Lucas plant (Refs. 13, p. 10; 99, p. 3). As documented in the
sections below, no other significant source of arsenic, other than the disposal areas used by Lucas plant, are
located within the Hilliards Creek watershed.

Similarly SV OCs are associated with all four of the site sources, being found in soil samples and free product
samples as discussed earlier in the source sections of this document.

The five sections below provide further information related to the attribution of arsenic and lead (as well as
the SVOCs found in the observed releases by direct observation) in Hilliards Creek to the Lucas plant.

The first section provides information on the land use surrounding Hilliards Creek. This section contains
both historical and recent information showing that the paint works area has been a main source of
contamination to the creek. It also discusses other facilities and other proposed and final NPL sites in the
watershed that might have contributed lead or arsenic to Hilliards Creek. However, releases from these
facilities would negate that part of the significant increase in contaminant concentrations at least in part is
due to the releases from the sources.

The second section describes investigations that have been conducted in Hilliards Creek to determine
whether the paint works area released hazardous substances to the creek. Besides the analytical data from
the most recent investigations used to document an observed release to surface water from the paint works
area by chemical analysis, a summary of previous investigations is provided in the section below to provide
additional documentation of releases to Hilliards Creek. These studies show that the lead and arsenic
concentrations are significantly higher below the PPEs for this site and the contamination appears to be
continuous from these PPEs downstream to Kirkwood Lake.

The third section describes documentation of historic releases from site activities to Hilliards Creek that have
been observed over time. It clearly supports that the paint works area is historically a source of lead and
arsenic releases.

The fourth section describes operations at the paint works area that may have released arsenic, lead, and
SVOCs to Hilliards Creek and Hilliards Creek wetlands.

The fifth section describes ground water releases directly to surface water.

Land Use Surrounding Hilliards Creek

Historical aerial photography indicates that, west of Gibbsboro-Clementon Road, land use along the course
of Hilliards Creek has changed over time. Historically, properties along that portion of the creek were used
for farming, but were gradually abandoned and either subdivided for residential development or were
acquired by the Borough of Gibbsboro under the Green Acres program. To the East of Gibbsboro-Clementon
Road, Hilliard Creek is bordered by a cemetery, Lucas plant, and residential properties (Refs. 3; 4; 5; 6, p.
2-11).

The 1964 insurance map of the Lucas plant identified Hilliards Creek as a drainage ditch located between
ASTs and a garage with a gasoline storage tank and pump. The map shows that Building 67 located east of
Hilliards Creek was used as a warehouse, with a railroad and tanker truck solvent unloading station at its
northern side and a sewage treatment plant and drum storage area to its southern side. This same map also
shows the Lucas plant former wastewater lagoon located directly south of Building 67 and east of Hilliards
Creek (Refs. 5; 6, p. 2-13).

The 1947 site map shows drainage from the above ground solvent storage tanks flowing in an eastern
direction into Hilliards Creek. The maps indicated that the ground slopes to a small brook (Hilliards Creek).
The map indicates a flood occurred in September 1940 that broke a dam wall and caused water to enter parts
of the building to a depth of 4 to 5 feet (Refs. 3; 6, p. 2-12).

A historical report about Gibbsboro New Jersey provides historic information related to the land-use
surrounding Hilliards Creek. In the 1800s, Gibbsboro was used mainly for farming (Ref. 17, p. D4) and a
grist mill operated on Hilliards Creek (Refs. 17, pp. D7, D16; 60, p. 15). The Lucas plant began operating
in the mid-1800s and houses were constructed in the area around Hilliards Creek (Ref. 17, pp. D10, D16).
A railroad provided transportation of goods (Ref. 17, p. Dll). The only manufacturing conducted in
Gibbsboro in 1906 was done by the Lucas plant (Ref. 17, p. D-18). In 1924, Gibbsboro was a self-contained
community of workers who for the most part were engaged in the production of Lucas Paint and Varnish
Products (Ref. 17,p.D-18). Inl931 the Labrusca Vineyard and a concrete block manufacturer were located
in Gibbsboro (Ref. 17, p. D-20). In 1960, the Labrusca Vineyards closed and 500 homes were constructed
on the 100-acre parcel (Ref. 17, p. D-20). The Lucas plant was the major industry in Gibbsboro, New Jersey,
from the 1800s to 1970s (Ref. 60, p. 6).

The date at which lead was no longer used at the Lucas plant has not been determined. During the 1940s and
1950s, paint manufacturers essentially discontinued the use oflead pigments in consumerpaints and in 1954,
a voluntary standard to remove lead pigment from consumer paints, was developed by the American
Standards Association (Ref. 106). The lead contamination in Hilliards Creek is expected to have moved
downstream from the plant, since the lead discharges from the plant ceased over 50 years ago. Additionally,
discharge from the former lagoons (Source 3) containing lead-contaminated wastewater ceased in 1977, over
28 years ago (Ref. 31, p. 2-5). The concentrations oflead detected in Hilliards Creek, as documented earlier
in this section, also indicate that the lead contamination from the Lucas plant has migrated downstream. For
example, at sampling location HC-SD-45, lead was detected up to 5,220 mg/kg (Refs. 86, p. 17; 88, p. 2).
The sampling location is about 6,600 feet downstream from PPE-4, the most upstream PPE (Ref. 97).

West of the site, on Kirkwood Lake, an ice harvesting company and gristmill operated in the early 1900s
(Refs 9; 49, p. 2-1).

Other Possible Facilities and Off-Site Sources

A gun club is located on Bridgewood Lake (43, p. C-2-5). Bridgewood Lake flows to Hilliards Creek (Ref.
9). The gun club is a potential source oflead contamination from lead bullets. Releases from the gun club
would not be a source of arsenic.

Academy Paints and Scotko Sign and Display, Inc. are facilities listed as RCRA facilities and are generators
of hazardous waste (Refs. 31, p. 2-6; 59, Appendix n, p. 1110 ). Both are tenants of the industrial park that
replaced the Paint Works facility (Refs. 31, p. 2-6; 56, Appendix 119). Scotko Sign and Display, Inc.
occupied Building 56 (Ref. 31, p. 2-7). Academy Paints manufactured paint (latex and oil based) from 1982
to 1989 in Building 67 (Refs. 67, p. 1; 31, p. 2-6). Academy Paints used the following materials: toluidine,
ammonia 260, driers (solvents), ethylene glycol, flammable liquids, naphtha, paint, potassium chlorate, resin
solution, mineral spirits, xylene, and ethylbenzene (Refs. 33, p. 9; 67, pp. 7, 8;). Two 5,000-gallon ASTs
were located north of the Academy Works building, which stored solvents, alkyl resins, and mineral spirits.
Fifty-five-gallon drums were located on the back of the building on a concrete pad as well as directly on the
ground (Ref. 59, Appendix n, 1110).

Several commercial and industrial operations are present in the immediate vicinity of the plant. A former
gasoline service station, previously leased to CITGO and the Sun Oil Company, was located directly
northeast of the intersection of Foster Avenue and US Avenue, east of the Lucas plant, within 120 feet of
Building 55 (Ref. 31, p. 2-17 and Figure 3-2).

The former General Electric (GE) Company Aerospace Government Electronic Systems facility is located
immediately to the north of the facility, at the intersection of Route 561 and US Avenue. When it was in
operation, the facility was listed on the Toxic Release Inventory (TRI) as releasing to the air and disposing
of 1,1,1 -trichloroethane off site.

Additionally, numerous RCRA facilities are located in Gibbsboro but are not associated with significant
releases of lead or arsenic (Ref. 31, p. 2-17).

Hazardous wastes sites identified within 1 mile of the Hilliards Creek site include the Shell gasoline service
station and the Buzby landfill (Ref. 59, Appendix n, p. 118).

The concentrations of lead in Hilliards Creek may be partially attributable to surface runoff from nearby
roads and parking lots and the former use of leaded fuels (Ref. 59, Appendix II, 1156).

Land uses in the area of Hilliards Creek that may have contributed to the PAH contamination in Hilliards
include wood burning, exhaust from automobiles and trucks, and runoff from asphalt roads (Refs. 9; 105,
pp. 2, 3, 4).

If during further investigation releases from these above mentioned facilities or sources are found to be
contributing significant contamination to Hilliards Creek, appropriate actions will be undertaken and, if
appropriate, will be included as part of this site. However, they are not thought to be ongoing sources of lead
or arsenic.

NPL and Proposed NPL Sites

Two hazardous waste sites are located a short distance from the Lucas plant, Route 561 Dump Site, and the
US Avenue Burn Site (Ref. 41, p. 6). The US Avenue Burn Site is listed on the NPL and the Route 561
Dump Site has been proposed for listing on the NPL (Refs. 44, p. 1; 45, p. 2). The sites are described below.
Locations of the sites are shown on Figure 2-1 of Reference 6.

US Avenue Burn Site

The US Avenue Burn site, a site listed on the NPL, was used and owned for waste management by the Lucas
plant. The site was used for the disposal of wastes generated solely by the Lucas plant. The site is located
approximately 500 feet southeast of Building 67 on the Lucas plant property on vacant land east of
BridgewoodLake in Gibbsboro, New Jersey. The site includes, but is not limitedto, three sources: the Burn
Area, the Burn Landfill, and the Railroad Track. The Burn Area portion of the site was previously used for
disposal and burning of paint wastes from the Lucas plant. The Burn Landfill portion of the site was used
for the disposal of sludge from the Lucas plant's wastewater treatment system. The Railroad Track portion
of the site was used to transport materials to and from the Lucas plant (Refs. 45, pp. 1, 2; 6, p. 2-6, Figure
2-1).

Hazardous substances detected in samples from the Landfill Area included barium, cadmium, lead, and zinc
(Ref. 61, pp. 7, 8). Analytical results for soil samples from the Burn Area indicated antimony, arsenic,
barium, cadmium, total chromium, copper, lead, and zinc (Ref. 61, p. 9). Contaminated soil is associated
with the Railroad Track portion of the US Avenue Burn site. Hazardous substances detected in the soil
include arsenic, barium, chromium, and lead (Ref. 61, p. 7).

White Sand Branch and Haney Run Brooke flow across the US Avenue Burn site into Bridgewood Lake,
which discharges into Hilliards Creek downstream of the Lucas plant (Refs. 97; 6, Figure 2-1). The Burn
Area source of the US Avenue Burn site is located in a wetland of White Sand Branch. The wetland is
contaminated (Ref. 61, pp. 3, 6). During the investigations conducted at the site, the field crew observed
the presence of discolored soils (green) along a section of the railroad track used to transport materials (Ref.
59, Appendix Z, p. Zl, Appendix FF, p. FF1).

Route 561 Dump Site

The Route 561 Dump Site, a site proposed for listing on the NPL, is located approximately 1,000 feet
northeast of Building 55 on the Lucas plant property on a vacant parcel located on Route 561 near
Milford/Kresson Road in Gibbsboro, New Jersey. The site was previously owned and used by the Lucas
plant as a paint waste disposal area (Refs. 44, p. 1; 61, 3; 9; 6, p. 2-9). The Route 561 Dump site released
paint wastes, arsenic, and lead into White Sand Branch, which eventually discharges into Bridgewood Lake
(Refs. 9; 59, pp. 10, 11, 13, 17). White Sand Branch flows south through the Route 561 Dump Site and
leaves the site through a culvert under Route 561 and continues southwest to Bridgewood Lake.
Bridgewood Lake flows into an unnamed tributary that converges with Hilliards Creek downstream of the
Lucas plant (Refs. 44, p. 1; 61, 3; 9; 6, p. 2-9). Analytical results for soil samples collected from the dump
site indicated the presence of arsenic, barium, cadmium, and lead. Arsenic and lead were also detected in
sediment samples from White Sand Branch (Ref. 61, pp. 6, 7).

Investigations of Hilliards Creek

This section describes investigations conducted of Hilliards Creekthat were not used in the observed release
to surface water section of this HRS documentation record.

Investigations of Hilliards Creek 1983 to 1991

On February 7, 1985, NJDEP personnel sampled Hilliards Creek and a seep (Source 1) discharging into
Hilliards Creek (Ref. 32, p. 5). Analytical results for creek samples indicated the presence of benzene,
ethylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, xylenes, and toluene (Ref. 32, p. 6).

In March 1987, NJDEP collected surface water samples from Hilliards Creek at the point where a seep
(Source 1) discharged into the creek and upstream and downstream of the seep. The upstream surface water
sample contained less then 5 micrograms per liter (fxg/L) of lead and the surface water sample collected at
the seep contained 450 (xg/L of lead (Refs. 62, pp. 16, 63; 64, p. 10).

In 1991, two sediment samples were collected from Hilliards Creek near the seep, Source 1. Analytical
results for the samples indicated the presence of numerous SVOCs (Ref. 59, Appendix II, 113 8).

Remedial Investigations - Hilliards Creek

From August 1991 through January 1992, during a Phase I RI for the Lucas plant (Ref. 31, p. 3-3), three
sediment samples (001-SD01, 002-SD01, and 003-SD01) were collected from Hilliards Creek. No
background sediment sample was collected in Hilliards Creek. Analytical results for the sediment samples
indicated the presence of numerous SVOCs including acenaphthene, acenaphthylene, anthracene,
benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, carbazole, chrysene, di-n-octyl phthalate,
dibenzo(a,h)anthracene,dibenzofuran,fluoranthene, fluorene,indeno(l,2,3-cd)pyrene, pentachlorophenol,

phenanthrene, and pyrene. Numerous metals were also detected in the sediment samples (Ref. 31, Table 4-
16). However, since metals are naturally occurring and no background sediment sample was collected, the
significance of the metal concentrations can not be determined.

Three surface water samples (001-SW01, 002-SW01, and 003-SW01) were collected from Hilliards Creek
during the Phase IRI. A background surface water sample (004-S WO 1) was collected from the northeastern-
most point of Silver Lake, upgradient of sources on the Lucas plant property to provide data representing
background conditions (Ref. 31, pp. 3 -3, 3 -12,3 -17). Hazardous substances detected in the Hilliards Creek
surface water samples at concentrations greater than three times the background concentration (with the
consideration of data qualifiers) or above the detection limit if not detected in the background sample include
benzene, xylene, phenols, aluminum, arsenic, chromium, copper, lead, magnesium, manganese, vanadium,
and zinc (Refs. 31, Table 5-8; 81).

From September 1996 through January 1997, during Phase IV of the RI, one sediment sample (SD-09) was
collected in Hilliards Creek immediately adjacent to the former pump house, at Source 2 (Ref. 31, pp. 3-3,
3-26). The sediment sample contained the highest concentrations of poly chlorinated aromatic hydrocarbons
(PAHs), ranging from 1.7 to 31 mg/kg, of all the sediment samples collected during RI activities. These
results indicate that the contaminated soil associated with the pump house has released PAHs to Hilliards
Creek (Ref. 31, pp. 5-13, 6-8, Table 4-16).

November 1998 Soil and Sediment Investigation Hilliards Creek

In 1998, lead contamination in Hilliards Creek was identified when sediment samples were collected from
the creek to establish reference (background) concentrations. One of the sediment samples collected from
the creek contained 221,900 ppm of lead. That sample was collected adjacent to a trail in the Hilliards Creek
Wildlife Refuge (Ref. 54, pp. 1, 5). To determine the source of the lead contamination, numerous
investigations were conducted by EPA.

As documented in the Observed Release Section of this HRS documentation record, in December 1998,676
sediment samples, 42 soil samples, three waste samples, and eight aqueous samples were collected from
Hilliards Creek and tributaries to Hilliards Creek. Blue-stained material, believed to be paint, was observed
in the sediments of Hilliards Creek and in soil adjacent to the creek (Ref. 26, Table 1, p. 5). The report
documenting the November 1998 sampling event, concluded that significant concentrations of lead were in
the sediments of Hilliards Creek and its tributaries, and in the soil surrounding the creek (Ref. 26, p. 6). One
of the samples collected from the bank of the creek, which was noted as containing blue-stained material
(believed to be paint), contained Resource Conservation and Recovery Act (RCRA) hazardous concentrations
of lead (greater than 5 milligrams per liter) (Refs. 26, Table 1, pp. 5, 6; 27, p. 12). The NJDEP residential
direct contact soil cleanup criteria (RDCSCC) of 400 ppm was exceeded in 437 of the sediment and soil
samples (Ref. 26, p. 6). The concentrations of lead in the shallow and deep sediment samples did not vary
significantly. The highest concentrations of lead were detected in sediments collected from the portion of
Hilliards Creek within the property boundaries of Hilliards Creek Wildlife Refuge (Ref. 26, p. 7). Hilliards
Creek Wildlife Refuge is located on the west side of Gibbsboro-Clementon Road, approximately 1,200 feet
southwest of the Lucas plant (Ref. 97). During the investigation, analysts identified lead contamination in
Hilliards Creek extending from Hilliards Road upstream to a distance of 4,600 feet (Ref. 26, p. 8).

During the November 1998 investigation, a sediment sample was collected from Hilliards Creek containing
blue material or paint, and was analyzed for TAL metals. The following metals were detected in the
sediment sample: aluminum(l l,700ppm), arsenic (l,280ppm), chromium (29,300ppm), iron(47,300ppm),

142

lead (68,000 ppm), and zinc (8,830 ppm). Analytical results forthe sample (W-l) containing blue material
collected from the hank of Hilliards Creek indicated aluminum (12,400 ppm), arsenic (759 ppm), barium
(2,870 ppm), chromium (38,500 ppm), and lead (65,000 ppm) (Refs. 26, p. 7 and Table 1, p, 5; 27, p. 11).
Two other samples containing blue-green stained material were collected from the flood plain of Hilliards
Creek downstream of the Lucas plant. These samples contained barium (up to 14,400 ppm), lead (up to
1,090 ppm), magnesium (up to 7,340 ppm), and mercury (up to 17.8 ppm) (Refs. 26, pp. 5, 7, 8; 27, p. 11,
Figure 2).

1999 Soil Investigation Hilliards Creek

In June 28,1999,155 soil samples were collected to define the extent of lead in the soil adjacent to Hilliards
Creek. The samples were analyzed on site using X-ray Fluorescence (XRF). Sixteen samples were analyzed
for TAL metals (Ref. 29, p. 2). Lead was detected in silt-rich soils in Hilliards Creek flood plain. Lead
concentrations decreased to a nondetectable level in areas up slope from the flood plain. The highest lead
concentrations were detected in samples containing blue-green clayey material (Ref. 29, p. 3).

1999 Health Consultation Hilliards Creek

In 1999, the Agency for Toxic Substances and Disease Registry (ATSDR) completed a health consultation
for Hilliards Creek. ATSDR evaluated the analytical data collected in 1998 where lead was detected at
221,900 ppm in a sediment sample collected in the Hilliards Creek Wildlife Refuge. ATSDR concluded that
an urgent health hazard exists to children and adults who use the refuge. The area where the sediment sample
was collected was expected to be visited frequently because a trail in the refuge brought visitors to the
sampling location (Ref. 55, pp 4, 8).

1999 Administrative Order of Consent Hilliards Creek

On September 30,1999, the EPA Region 2, Regional Administrator and Sherwin-Williams signed an AOC
for a removal action that required Sherwin-Williams to delineate the extent of contamination at accessible
areas along Hilliards Creek; prevent direct contact with the contamination by use of engineering controls in
accessible areas; obtain access; post signs where appropriate; and conduct site inspections on a quarterly
basis (Refs. 49, P. 1-1; 50, pp. 1-1, 1-2; 51, pp. 1, 2, 22, 23). The removal action under the AOC also
included sampling of Hilliards Creek and residential properties near Hilliards Creek to delineate the extent
of lead-contaminated soil and the installation of a fence around lead-contaminated soil adjacent to Hilliards
Creek (Ref. 51, pp. 9 through 14).

Between December 1999 and January 2000, sediment and soil samples were collected from 16 transects (T1
throughT15 andT17) across Hilliards Creek between Gibbsboro-Clementon Road and Hilliards Road. The
transects were spaced approximately 200 feet apart. Samples were collected at approximately 30-foot
intervals along each transect from each bank of Hilliards Creek and from the center of Hilliards Creek. The
surface soil samples collected from the banks of Hilliards Creek were collected from within the 100-year
flood plain of Hilliards Creek. The flood plain samples were collected to determine whether periodic
flooding transported contaminated sediments from Hilliards Creek to the flood plain of Hilliards Creek.
Additional samples were collected as needed to complete the horizontal and vertical delineation of lead
contamination, including four soil boring samples at various depths from the southern berm of the manmade
pond located off of Gibbsboro-Clementon Road (Ref. 51, pp. 5, 8).

143

All samples were analyzed for lead (Ref. 51, p. 5). Approximately 25 percent of all samples were analyzed
for TAL metals plus cyanide, five percent for TCLP metals (including copper and zinc), and five percent for
TCLP VOC and BNA analyses. All sediment samples collected during the initial round of sampling were
submitted for pH, TOC, and grain size analyses (Ref. 51, p. 6). All samples were collected in accordance
with the November 1999 Work Plan for the Hilliards Creek Site, Gibbsboro, New Jersey and the December
1999 Work Plan Addendum (Refs. 51, p. 4; 68, 69).

No sediment sample designated to be background for all of Hilliards Creek was collected. However, a
transect (T17) was placed across Nicholson Branch, a tributary of Hilliards Creek. The transect included
the collection of surface and subsurface soil and sediment samples from the two flood plain banks and the
center of Nicholson Branch (Ref. 51, pp. 5, 8, and Figure 4). Nicholson Branch is similar in size to Hilliards
Creek, located within the same drainage area, and has similar soil/sediment types (Refs. 31, pp. 2-7 through
2-10; 6, Figure 2-7). The samples collected from transect 17 in Nicholson Branch are used to establish
background lead levels in sediment located within Hilliards Creek. A summary of analytical results for
sediment samples indicating concentrations of lead above three times the background concentration is
provided in the Tables 17 and 18. The background samples were analyzed for lead only (Ref. 51, Table 4c,
p. 14, Figure 4). Therefore, lead is the only metal evaluated.

Ten surface water samples also were collected from nine sampling locations where lead was detected at
elevated concentrations as compared to background (Ref. 51, p. 6, Figure 5). The samples were analyzed
for TAL metals (filtered and unfiltered), TOC, total dissolved solids (TDS), totals suspended solids, and
hardness. The samples were collected from a depth of approximately 2 inches below the top of the water
surface (Ref. 50, p. 6). No background surface water sample was collected (Ref. 51, Figure 5). To determine
whether the concentrations of hazardous substances detected in the surface water samples are three times
above the background concentration, surface water sample SW-09 collected from a tributary draining
Bridgewood Lake is used to establish background concentrations (Ref. 51, Figure 5). The tributary does not
receive surface water runoff from the Lucas plant, but does receive surface water runoff from two hazardous
waste sites, US Avenue Burn Site and Route 561 Dump Site (Ref. 6, Figure 2-1). As summarized in Table
19, concentrations of arsenic and lead were detected at three times above the background concentration in
surface water samples SW-07 and SW-08. Lead was detected in surface water sample SW-05 at
concentrations three times the background concentration as documented in the table below. The hardness,
TDS, TOC, and total suspended solids values are presented for water quality information and are not used
to establish an observed release of these values.

In response to results of samples collected during investigations along Hilliards Creek, Sherwin-Williams
fenced areas of the Hilliards Creek Wildlife Preserve and Hilliards Creek to limit access to lead-contaminated
soil and sediment (Ref. 51, pp. 9, 10, 11).

June 2002 Investigation

In June 2002, Sherwin-Williams conducted a sampling investigation at Kirkwood Lake, the surface water
into which Hilliards Creek discharges, and residential properties adjacent to Kirkwood Lake (Ref. 49, pp.
2-1, Figure 2, Table 1). The investigation identified arsenic and lead contamination in Kirkwood Lake and
on one residential property (Ref. 49, pp. 3-7, 3-9, 3-10, 4-1, 4-2).

Historic Discharges into Hilliards Creek

Sherwin-Williams had a permit for discharging non-contact cooling water into Hilliards Creek from the
Lucas plant under a NJDEP National Pollution Discharge Elimination System (NPDES) permit. The
discharge ceased in August 1978 when the plant closed (Refs. 58; 59, p. 6).

A historic map of the Lucas plant indicates that hazardous substances stored and used in buildings on the
plant property may have been released to Hilliards Creek. The maps indicated that Hilliards Creek originated
at Silver Lake. Silver Lake discharged into an underground culvert that flowed under buildings located at
the plant and finally to an open ditch, Hilliards Creek, on the east side of Foster Avenue. Building floor
drains, a trench, a holding basin, and surface water run off from the plant were directed to the underground
culvert that discharged into Hilliards Creek (Refs. 6, Figure 2-4; 60, pp. 16, 25, 28, 29, 62). Hazardous
substances used and stored in buildings may have been released to Hilliards Creek through this pathway.
As indicated by historic maps, numerous types of hazardous substances were used in the plant buildings
(Refs. 6, Figure 2-4; 60).

There is also evidence that the surface impoundments (Source 3) leached their contents into Hilliards Creek
(Ref. 32, p. 3). Aerial photographs taken in 1973 show the presence of a pipeline extending from the north
bank of one of the surface impoundments (impoundment one) to a drainage channel (Hilliards Creek) that
runs through the center of the Lucas plant. An outfall from the western bank of the impoundment area
toward the drainage channel (Hilliards Creek) is visible (Ref. 7, p. 10).

On September 18,1915, Building 39 was almost completely destroyed by fire (Ref. 60, p. 67). On February
21, 1940 and July 30, 1949, fires occurred at the facility (warehouse No. 36), which ignited thousands of
gallons of drummed thinners, lacquer, and other flammable materials stored at the facility. During efforts
to extinguish the fires, hazardous substances were released to soil, ground water, and surface water (Refs.
32, p. 3; 60, p. 68).

On May 5, 1976, NJDEP inspectors observed that a feed pipe used for the transport of raw materials had
ruptured, causing an oil discharge to the primary settling lagoon (Source 3) and Hilliards Creek (Ref. 32, p.
3). The reference to the release does not indicate the exact type of the material discharged. This discharge
may have released contaminants to Hilliards Creek.

In 1983, a seep (Source 1) was observed in the parking lot north of Building 67 between Buildings 67 and
50, flowing into Hilliards Creek (Refs. 32, p. 5; 65, pp. 1, 2, 3). The seep was observed on many occasions
during the construction of the new office complex that now occupies the Lucas plant property. Two UST s,

149


-------
SWOF - Attribution

one for oil and another for solvent, were located in the area of the seep. There also was a loading pad for
railroad cars in this area (Ref. 65, p. 1). The loading pad and the USTs may have been one of the sources
of the seep. The seep flowed overland to a storm water catch basin in the parking lot and then discharged
into Hilliards Creek (Refs. 32, p. 5; 65, pp. 1, 2, 3). Analytical results for a sample of the seep is presented
in the waste characteristics section for Source 1 in this HRS documentation record.

On February 7, 1985, NJDEP personnel sampled Hilliards Creek and the seep (Source 1) discharging into
Hilliards Creek (Ref. 32, p. 5). Analytical results for the seep sample indicated the presence of 1,2,4-
trimethylbenzene, 1,3,5-trimethylbenzene, naphthalene, xylenes, ethylbenzene, cumene, and
tetrachloroethene (Ref. 32, pp. 6, 7). Analytical results for creek samples indicated the presence of benzene,
ethylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, xylenes, and toluene (Ref. 32, p. 6).

On May 11, 1987, NJDEP personnel witnessed Paint Works's employees (persons employed by the Paint
Works Corporate Associates I who purchased the Lucas plant from Sherwin-Williams) pumping hazardous
substances into Hilliards Creek. On June 11,1987, NJDEP personnel witnessed hazardous substances being
discharged to Hilliards Creek through a ditch dug by Paint Works's employees. On June 4, 1987, NJDEP
personnel observed Paint Works' fill in a section of Hilliards Creek with contaminated soils (Ref. 32, p. 8).
The reference documentation for the above releases does not identify the hazardous substances released.

In 1994, during investigations at the US Avenue Burn Site, a NJDEP representative interviewed a resident
of 25 US Avenue. The resident's interview indicated that Hilliards Creek was commonly known as the Paris
Green ditch where the washout from the Paint Works facility ran different colors on different days (Ref. 59,
Appendix BBB, pp. BBB3, BBB4). Another residence of Gibbsboro indicated that during the 1950s, he
observed a rainbow sheen across Hilliards Creek and he soaked cattails in the material seeping into the creek
in order to make torches (Ref. 64, p. 8).

On February 19,1988 and February 25,1988, NJDEP observed a seep (Source 1) discharging into Hilliards
Creek (Refs. 36; 37). On several occasions in 2002, as documented in the source characterization section
for Source 1, seeps were observed flowing into the Hilliards Creek at the point where the storm sewer north
of Building 67 discharges into the creek (Refs. 72, pp. 2, 4; 73, pp. 2, 4). As documented in the source
characterization section for Source 1 and Table 11, arsenic, lead, benzo(a)pyrene, bis(2-ethylhexyl)phthalate,
and chrysene were detected in seep samples and in Hilliards Creek sediment samples at concentrations
meeting the criteria for an observed release (Ref. 1, Table 2-3).

On March 30, 1989, NJDEP received a complaint of an illegal discharge of white paint solids into Hilliards
Creek from Academy Paints and issued a notice of violation to Academy Paints (Refs. 34; 35).

On April 9,2002, free-phase product from the seep (Source 1) was observed in the storm water system catch
basin and inlet, in the rip-rap, and in Hilliards Creek (Ref. 48, p. 2-3). The product was characterized as
waste petroleum distillates (Ref. 48, Appendix A). The free product was composed of benzene,
ethylbenzene, xylene, naphthalene, and 2-methylnaphthalene (Ref. 31, p. 4-25).

Arsenic, lead, and SVOCs have been detected in soil samples collected from sources on the Lucas plant
property (documented in the waste characterization section of this HRS documentation record), and surface
water runoff from the sources are not contained (as documented in the source description section of this HRS
documentation record). Surface water carried metals and SVOC-contaminated soil into Hilliards Creek as
documented in Section 4.0 of this documentation record (Ref. 31, p. 6-9).

Additionally, lead and SVOCs have been detected in product samples collected from Source 1 (Refs. 76, pp.
12,13, 19, 20; 77, p. 82). Product from Source 1 has been observed discharging into Hilliards Creek (Refs.
10, pp. 1, 2; 31, pp. 3-3, 3-22; 32, p. 5; 65, pp. 1, 2, 3; 36; 37).

Contaminant Sources Associated with Site Operations

Historic illustrations showing areas where white lead grinding operations were conducted do not show any
air emission controls on the grinding equipment (Ref. 60, pp. 42,43,44,45). During the grinding operations,
lead would have been released to air and may have been deposited in Hilliards Creek and surrounding areas.
Similarly, many operations shown in the historic illustrations like boiling and cooling varnish, mixing
varnish, drum storage areas, latex storage, and solvent transport may have released lead and other hazardous
substances (Ref. 5). Many of the historic illustrations show equipment on wooden floors or directly on the
ground surface (Ref. 60,pp. 33, 35 through 41,46, 51,52, 53, 55). The historic descriptions of the buildings
indicate that the buildings did not have containment structures and were not constructed to prevent spills
from percolating into the underlying soil (Ref. 60, pp. 90, 91, 94 through 108).

Historic reports indicate that the varnish operation produced air emissions and the lacquer and paint
operations produced highly toxic liquid waste. Arsenic wastewater produced from the color works was
pumped to an open field outside Gibbsboro in the 1930s (Ref. 60, p. 69). Some of the residents recall that
the field frequently caught fire (Ref. 60, pp. 69,71). Residents also recall a time when Hilliards Creekwould
catch fire when solvents on its surface ignited (Ref. 60, p. 71). To resolve this problem, Sherwin-Williams
added a scrubber to the alkyd plant stack and contained wastewater in pits behind old Number 36 platform
(Ref. 60, p. 71).

Operations in the area of Tank Farm B (Source 4) are a probable cause of the soil contamination in this area.
Hazardous substances may have leaked or released during the transportation of the tank contents by tank cars
to the production facilities or from a system of pipes installed in 1911 to simplify the transportation process,
former ASTs and USTs, an existing septic system, and historical use of process chemicals (loading and
unloading) within the area (Refs. 59, Appendix n, p. 115; 60, p. 46). The area of Tank Farm B was referred
to as oil hill (Ref. 60, p. 46). The tanks contained oils, mineral spirits, and xylene (Ref. 31, Table 2-2).

In September 1987 and February 1988, NJDEP determined that the analysis of seep (Source 1) samples
indicated that the constituents in Source 1 were similar to the materials used and stored at the Sherwin-
Williams facility (Ref. 38, pp. 1 through 3). The seeps (free-phase product) may have resulted from leaks
from ASTs containing mineral spirits 66-2 and 802-15 alkyd resin, a pipe extending from the maintenance
shop in Building 50, a former gasoline station, an existing septic system, or the handling of process chemicals
during operations (Refs. 18, pp. 3-5, 4-1; 59 Appendix II, p. 115). A surface spill of motor oil also was
indicated as a source of contamination (Ref. 18, pp. 3-5, 4-1).

Contaminated soil on the plant property may be due to the storage of raw materials in Buildings 55 and 58
and improper handling of materials during transfer, leaking transfer piping, leaking drums and tanks, spills
during maintenance of pipes, spills during maintenance of pipes, pumps and tanks, spills during drum
cleaning activities, discharge of wastes to surface impoundments, and leaks due to improper storage of
drummed materials (Ref. 32, p. 9, Figure 2-2).

The reworking of the parking lot adjacent to Building 67 included the excavation of the cut-bank in the
northeastern corner of the parking lot to provide an additional area for parking. This reworking allowed free-
phase product and ground water to seep at the ground surface (Ref. 31, p. 6-3).

Analytical results for soil samples collected from the source areas indicated the presence of numerous
SVOCs, including those SVOCs detected in the release to surface water and sediment samples collected from
Hilliards Creek as documented in this section of the HRS documentation record (Refs. 31, Table 4-5; 78, p.
13). Surface water run off from the areas of contaminated soil, Sources 2, 3, and 4, would carry the
contaminated soil to Hilliards Creek.

Ground Water Contaminant Releases to Surface Water

Locally, Hilliards Creek acts as a discharge zone for shallow ground water (Ref. 31, p. 4-2). Therefore, any
shallow ground water contamination associated with the facility would eventually discharge into Hilliards
Creek. As discussed in the observed release by direct observation via overland flow section earlier in this
HRS Documentation Record and later in the Ground Water to Surface Water section of this HRS
Documentation Record, the ground water is in direct contact with free product underneath the paint works
area, and this free product and soils in the free product source area contain lead, arsenic, and SVOCs.

Similar types of wastes have been observed in the Route 561 Dump Site and in soil near Hilliards Creek and
in sediments of Hilliards Creek including blue and bluish-green staining or blue and bluish-green stained soil
and sediment (Ref. 59, Appendix Z, p. Zl; Appendix FF, p. FF1; Appendix GG, p. GG1).

In summary, lead, arsenic and several SVOCs are clearly associated with on-site sources. They are found
in observed releases by direct observation. They are found in significantly higher concentrations downstream
of the PPEs for the site sources, and historic documentation supports that these substances have been released
to Hilliards Creek numerous times. Although there may be other sources in the Hilliard's Creek Watershed,
it is clear that the significant increase in the release substances can be at least in part attributed to site
releases.

The source HWQ values for each of the four sources is greater than zero. As documented in Section 4.1.4.3,
wetlands are subject to Level I and II concentrations; therefore, a minimum value of 100 is assigned for the
HWQ value (Ref. 1, Section 2.4.2.2, Table 2-6).

The waste characteristic factor value is the product of the highest toxicity/persistence factor value and 11W Q
value, multiplied by the highest bioaccumulation factor value for the same hazardous substance (Ref. 1, Section
4.1.3.2.3). The hazardous substances with the highest toxicity/persistence factorvalue and bioaccumulation
factor value include benzo(a)pyrene, manganese, and mercury.

SWOF/Food Chain - Targets

4.1.3.3 HUMAN FOOD CHAIN THREAT - TARGETS
Actual Human Food Chain Contamination

Although aqueous and sediment samples document an observed release to the surface water migration pathway,
actual food chain contamination is not scored because no fisheries are documented within the areas of the
observed release (Ref. 1, Section 4.1.3.3).

4.1.3.3.1 Food Chain Individual

As documented in Section 4.1.2.1.1 of this HRS documentation record, an observed release of hazardous
substances having a bioaccumulation factor value of 500 or greater is documented at the Hilliards Creek
watershed and there is a fishery, Kirkwood Lake, within the 15-mile downstream TDL. The food chain
individual factor is assigned a value of 20 (Refs. 1 [Section 4.1.3.3.1]; 52, p. 5).

Food Chain Individual Factor Value: 20

(Ref. 1 [Section 4.1.3.3.1])

4.1.3.3.2.3 Potential Human Food Chain Contamination

Kirkwood Lake is the only fishery identified within the 15-mile downstream TDL. The value for the potential
human food chain contamination factor for Kirkwood Lake is assigned a value of greater than zero because
information related to annua! production of the lake has not been documented. However, since the lake is a
fishery, the production value would be greater than zero (Ref. 52, p. 5).

Potential Human Food Chain Contamination Factor Value: >0

(Ref. 1 [Section 4.1.3.3.2.3])

Level I Concentrations

Actual environmental contamination has been documented in the wetland of Hilliards Creek and in Hilliards
Creek, as documented in Section 4.1.1.1 of this documentation record. The sampling locations and wetland
are shown on Reference 97. The wetland is identified on Reference 93, Wetland Inventory Map, and
electronically transposed onto Reference 97 for clarity. The wetland is a palustrine forested broad-leaved
deciduous and needle-leaved evergreen, and palustrine scrub/shrub and emergent wetland (Ref. 93). The Level

The concentrations of hazardous substances detected in surface water samples documenting an observed release
to surface water and the corresponding benchmark are listed in Table 24. The concentrations of hazardous
substances detected in the samples are documented in Table 12. The environmental benchmarks are EPA's
ambient water quality criteria (AWQC), as presented in National Recommended Water Quality Criteria: 2002
(EPA-822-R-02-047) (Ref. 1, Table 4-22). To use the AWQC, the criteria are adjusted in relation to the
hardness of the aqueous sample. Reference 95 provides the AWQC for each aqueous sample adjusted for the
sample-specific hardness values (Refs. 2, p. 28; 95). The AWQC provide criteria maximum concentrations
(CMC) and criteria continuous concentrations (CCC) (Ref. 2, pp. BII-1, BII-8). Therefore, CMC and CCC for
each aqueous sample are calculated to determine the sample-specific CMC and CCC with consideration of the
hardness value for the sample. The CCC is the chronic benchmark and is used to determine actual
contamination in accordance with Reference 1, Table 4-22.

4.1.4.3.1.1 Level I Concentrations
Sensitive Environments

Sensitive environments other than wetland have not been identified within the 15-mile downstream target
distance.

Wetlands

The wetland areas were identified from Reference 93, Wetland Inventory Map. The wetland is a palustrine
forested broad-leaved deciduous and needle-leaved evergreen, and palustrine scrub/shrub and emergent wetland
(Ref. 93). The sampling locations identified in the Level I Concentrations section above are within this
wetland (Ref. 97). The wetlands subject to Level I concentrations are those wetlands located between PPE-1
and the most distance downstream Level I sampling location (HC-SW-39) (Ref. 1, Section 4.1.1.2).

The total length of wetlands from PPE-1 to the most downstream sampling location (HC-SW-39) containing
Level I concentrations is estimated to be 5,708 feet (Refs. 93; 97). Since wetlands are located on both sides
of Hilliards Creek, the total length of wetlands subject to Level I concentrations is two times 5,708 feet or
11,416 feet or 2.16 miles (Ref. 1, Section 4.1.4.3.1.1). The wetland frontage is summarized in Table 25.

4.2

GROUND WATER TO SURFACE WATER MIGRATION

The ground water to surface water migration component is included to evaluate the threats that result from
migration of hazardous substances from a source to surface water via ground water (Ref. 1, Section 4.2).

Surface water eligible for evaluation in the ground water to surface water migration pathway includes those
surface waters within 1 mile of the sources. Additionally, no aquifer discontinuity can be located between
the sources and the surface waters, and the top of the uppermost aquifer must be at or above the bottom of
the surface water (Ref. 1, Section 4.2.1.1). Eligible surface water bodies include Hilliards Creek, Silver
Lake, White Sand Branch, Haney Run Brooke, and Bridgewood Lake (Ref. 9). The threats posed to Silver
Lake, White Sand Branch, Haney Run Brooke, and Bridgewood Lake are not evaluated. Only the threats
posed to Hilliards Creek are evaluated because the Hilliards Creek migration pathway yields the highest
ground water to surface water migration score. An observed release to Hilliards Creek can be documented
and fisheries and actual contamination of wetlands are associated with the migration pathway, as documented
in the sections below (Refs. 9; 31, Figures 2-2 and 3-2). Evaluation of the other eligible surface water bodies
does not change the site score. Hilliards Creek, as documented in Section 4.0 of this HRS documentation
record, is the primary surface water body threatened by releases from the Lucas plant. Available
documentation indicates that a release of lead to Bridgewood Lake may have occurred from the plant.
However, background samples were not collected to document background conditions. Additionally
Bridgewood Lake is not a fishery and the wetlands associated with the lake do not meet the minimum
frontage requirements of 0.1 mile for HRS evaluation. As a result, the target value for Bridgewood Lake is
very low.

Free-phase product in ground water and ground water seeps enter a storm sewer north of Building 67 when
the water table is high, indicating that there is no aquifer discontinuity and that the top of the uppermost
aquifer is at or above the bottom of Hilliards Creek (Refs. 6, p. 3-47; 18, p. 2-3). Locally, Hilliards Creek
acts as a discharge zone for the shallow aquifer (Ref. 31, pp. 4-2, 6-2).

4.2.1.2	Hazardous Substance Migration Path for Ground Water to Surface Water

The ground water to surface water migration pathway is restricted to the ground water segment in the
uppermost aquifer between the source and nearby surface water bodies. The surface water in-water segment
begins at the PPE from the uppermost aquifer to the surface water. The location of the PPE is the point of
the surface water that yields the shortest straight-line distance, within the aquifer boundary, from the sources
with a containment factor value of greater then 0 to surface water. As documented in the source section of
this HRS documentation record, the four sources evaluated have a containment factor value of greater than
0. The shortest distance from Source 1 to Hilliards Creek is the point at which the storm sewer north of
Building 67 discharges into Hilliards Creek, the same location as PPE-1 evaluated in the overland component
of the surface migration pathway (Refs. 10, pp. 1, 2, 3; 31, p. 34; 32, pp. 5, 6; 65, pp. 1, 2, 3; 97). Source
1 includes the sampling location MW-14 (see Section 2.4 of this documentation record for Source 1). The
shortest straight-line distance from Source 1 to Hilliards Creek is measured from MW-14. The shortest

distance to surface water from Source 2 is measured from the location of the contaminated soil sample (TB-
73) adjacent to the pump house, which is located adjacent to Hilliards Creek (Ref. 31, Figure 3-2) and is
shown in Reference 97 as PPE-3. The shortest straight line distance from Source 3 to Hilliards Creek is
obtained by traveling the distance from the lagoons along the pipeline that extends from the lagoons into a
drainage channel (Hilliards Creek), the same location as PPE-2 evaluated in the overland component of the
surface migration pathway (Ref. 97). The pipeline makes the shortest straight line distance to surface water
from Source 3 (Ref. 7, pp. 10, 11). The shortest straight-line distance from Source 4, Former Tank Farm B,
to Hilliards Creek is obtained from measuring at sampling location MW-17(Ref. 31, Figure 3-2) as shown
on Reference 98 as PPE-4. A summary of the PPEs is presented in the table below and illustrated on
Reference 98.

4.2.2.1.1 Observed Release to Ground Water

In this section, an observed release to the uppermost aquifer is established as specified in Section 3.1.1 of
Reference 1.

Regional Geology

The Lucas plant is located within the Atlantic Coastal Plain Physiographic Province. The Atlantic Coastal
Plain geology within Camden County is characterized by unconsolidated and semiconsolidated sediments
of Cretaceous through Quaternary ages consisting of alternating sand, silts, and clays. The sediments dip
gently to the southeast and thicken from approximately 40 feet at the Delaware River to over 2,900 feet at
the Camden-Atlantic County boundary. Below these unconsolidated sediments is pre-Cretaceous-age
bedrock (Ref. 109, pp. 1, 9).

177


-------
Ground Water (GW) to Surface Water (SW)
General Considerations

The Lucas plant is underlain by Pleistocene age sands of the Pennsauken Formation. The Pennsauken
Formation outcrops in irregular patches in Gibbsboro and ranges in thickness from a few feet to
approximately 30 feet. The Pennsauken Formation consists of medium- to coarse-grained quartzose sand,
gravel, and clay (Refs. 109, pp. 82, 83, 84; 31, p. 2-11, Appendix C).

The Kirkwood Formation underlies the Pennsauken Formation. The Kirkwood Formation consists of sand,
silt, and clay and reaches a thickness of approximately 80 feet in the vicinity of the Lucas plant (Refs. 109,
pp. 82, 83, 84; 31, p. 2-11).

Regional Hvdrogeology

The major freshwater aquifers in Camden County are sands and gravel of Cretaceous and Tertiary ages. The
Pennsauken and Kirkwood Formations are not typically used for potable water supply in Camden County.
The sands of the Pennsauken Formation and the upper section of the Kirkwood Formation form the shallow
subsurface of the Lucas plant and sources areas. These formations are approximately 20 to 30 feet thick in
the area of the plant and source areas and are generally hydraulically connected and form an unconfined
(water table) aquifer (Refs. 109, pp. 1, 9, 10, 22, 84; 31, p. 2-12 and Appendix C).

Aquifer Description

Ground water underlying the Lucas plant and sources at the plant occurs in two distinct zones: the shallow
zone (30 to 40 feet thick) and a deeper zone (total thickness unknown). The two zones are separated by a
silt unit (Ref. 31, p. 4-2). However, since releases of hazardous substances have been documented in both
zones, the two zones exchange water and are therefore interconnected and considered one aquifer, the
shallow aquifer (Refs. 1, Section 3.0.1; 31, pp. ES-l,ES-2, 5-8, 6-2, 6-6). The shallow aquifer is the aquifer
evaluated.

Shallow Aquifer (Stratum Name: Pennsauken and Kirkwood Formation)

The shallow aquifer is composed of reworked native soils, silty sand, and silt and is approximately 40 feet
thick (Ref. 31, p. 4-1). The saturated thickness of this aquifer is approximately 30 to 40 feet. Depth to
ground water is between 1 to 15 feet bgs. Ground water elevations indicate that the shallow zone flows from
the northeast to the southwest towards Hilliards Creek (Ref. 31, p. 4-2, Figure 4-7). Locally, Hilliards Creek
acts as a discharge zone for the shallow aquifer (Ref. 31, p. 4-2).

Free-phase product, composed of benzene, ethylbenzene, xylene, naphthalene, and 2-methyl naphthalene,
has been identified in the shallow aquifer (Ref. 31, p. ES-6).

178


-------
GW to SW Component - Observed Release

Direct Observation

Free-phase product has been identified at nine monitoring locations: MW-11, MW-13, MW-21, MW-26,
MW-27, WP-1, WP-3, WP-12, and WP-14. The estimated thickness of the free-phase product is between
0.22 and 0.42 foot (Ref. 31, p. 4-18). The presence offree-phase product in the monitoring wells documents
hazardous substances in direct contact with the ground water. Hazardous substances associated with the free-
phase product include 2-methylnaphthalene 4-chloroaniline, naphthalene, chlorobenzene , ethylbenzene,
xylene, benzene, benz(a)pyrene, chrysene, fluoranthene, naphthalene, cumene, tetrachlorothylene, 1,2, 4-
trimethylbenzene, 1,3,5-trimethylbenzene, aluminum, arsenic, barium, chromium, copper, iron, lead,
magnesium, manganese, and zinc (Ref. 31, pp. 3-3, 3-15, 3-17, Figure 3-2, Table 4-20; Ref.. 32, pp. 6, 7;
Ref. 77, pp. 1,2, 75, 76; Ref. 78, pp. 1 through 4, 13, 15, 16; Ref. 79, p. 28). See Section 2.2.1 for additional
information.

During sampling events from June 1993 through October 1993, three well points (WP-1, WP-2, and WP-3)
were installed to delineate the free-phase product ground water plume detected in MW-13 (Ref. 31, pp. 3-3,

3-15).	Samples of free-phase product were collected from the MW-11 (located on the southern end of Tank
Farm A) and MW-13 (located east of Building 67) (Ref. 31, p. 3-17, Figure 3-2). Analytical results forthe
product sample collected from MW-11 on August 6, 1993 indicated the presence of 2-methylnaphthalene
(360 milligrams per liter [mg/L]), 4-chloroaniline (320 mg/L), naphthalene (930 mg/L), chlorobenzene (100
mg/L), ethylbenzene (at an estimated concentration of520 mg/L), and xylene (at 4,600 mg/L) (Ref. 31, Table

4-20).	The product sample collected from MW-13 on August 6, 1993 contained 2-methylnaphthalene (1,800
mg/L), naphthalene (6,200 mg/L), benzene (at 110 mg/L), ethylbenzene (1,200 mg/L), and xylene (2,100
mg/L) (Ref. 31, Table 4-20).

During sampling events from July 1995 through August 1995, 45 hand-augered borings were located
throughout the seep area to attempt to delineate the extent of free-phase product through photoionization
detector (PID) field screening and visual observation. No samples were collected from these locations (Ref.
31, pp. 3-3,3 -18). Additional monitoring wells were installed, and two rounds of ground water samples were
collected (Ref. 31, p. 3-19). On July 14, 1995, samples of the free-phase product were collected from the
MW-11 (located on the southern end of Tank Farm A), MW-13 (located east of Building 67), and MW-21
(southeast of Building 67) (Ref. 31, p. 3-17, Figure 3-2). Anaytical results forthe product sample collected
from MW-11 indicated the presence of naphthalene (at an estimated concentration of 600 mg/L),
ethylbenzene (66 mg/L), and xylene (2,500 mg/L). The product sample collected from MW-13 contained
naphthalene (at 3,200 mg/L), benzene (at 570 mg/L), ethylbenzene (at 1,400 mg/L), and xylene (at 7,500
mg/L). Analytical results forthe product sample collected from MW-26 indicated 2-methylnaphthalene (at
an estimated concentration of460 mg/L), naphthalene (1,600 mg/L), and xylene (420 mg/L) (Ref. 31, Table
4-20).

On April 10, 2002, samples of the free-phase product were collected and analyzed for VOCs, petroleum
products, and fingerprinted (Ref. 75, pp. 2,4,5). The concentrations of hazardous substances detected in the
product samples are in the units of micrograms per kilogram (j^ig/kg) indicating that the samples were
analyzed as a solid. Analytical results for the samples indicated the presence of benzene (up to 240,000
(ig/kg), ethylbenzene (up to 4,600,000 (ig/kg), xylene (up to 26,000,000 (ig/kg), naphthalene (up to 1,800,000

GW to SW Component - Observed Release

Chemical Analysis

Aquifer being evaluated: Shallow Aquifer

An observed release to ground water is documented by ground water samples collected from monitoring wells
located on the Lucas plant during RI activities. The background ground water samples are selected based on
whether the background and release ground water samples were collected within the same screened interval
and period of time, and whether the samples were analyzed for the same hazardous substances. All ground
water samples collected during the RI from 1990 to 1997 were analyzed by Weston Analytics Division, a
New Jersey-certified laboratory. All samples collected from 1998 to 2000 were analyzed by Severn-Trent
Laboratories (STL), a New Jersey-certified laboratory (Ref. 31, p. 3-37). Reference 111 provides a Quality
Assurance Project Plan used by Sherwin-Williams' environmental consultant. The plan provides analytical
methods, quantitation limits, and detection limits for some of the investigations conducted by Sherwin-
Williams' (Ref. 111). It is likely that these same methods were used for analyzing the samples summarized
in this section. Analytical data sheets from the laboratories and detection limits are not provided in the RI;
however, the RI report states that the analytical data are valid. The analytical results used to document an
observed release to ground water are considered usable and of known quality (Ref. 31, p.

3-38).	Table 3-1 of Reference 31 provides a summary of the analytical suite for the ground water samples.
The tables presenting the analytical results in the RI report provide only concentrations detected (Ref. 31,
Tables 4-9, 4-11, 4-14). Tables 4-9, 4-11, and 4-14 of Reference 31 provide a summary of the hazardous
substances detected in ground water samples. When concentrations of metals are reported in Tables 4-9,

4-11,	and 4-14 of Reference 31 as soluble, the reported concentration is for dissolved metal. The dissolved
metals concentrations are not used to document an observed release to ground water.

Background Concentrations:

Ground water investigations conducted at the Lucas plant have determined that the free-phase product plume
in the shallow aquifer is limited to the east of Hilliards Creek (Ref. 31, p. ES-4). The RI activities
determined, based on ground water elevations, the shallow aquifer flows from the northeast to the southwest
towards Hilliards Creek (Ref. 31, p. 4-2, Figure 4-7) and is divided into a shallow and deep zone (Ref. 31,
p. 4-2). Therefore, background well selection is based on whether the wells are screened within the same
relative depth of the shallow aquifer. The RI activities did not establish a location of a background well.
Therefore, wells installed on the Lucas Plant were reviewed to identify potential background well sampling
locations. The RI activities included the installation of monitoring wells at biased locations or locations
where contamination was expected to be located based site use history or previous sampling activities.
Therefore, the majority of the monitoring wells located on the Lucas plant were installed in areas of potential
contamination. No monitoring well located outside the influence of potential sources of contamination on

the Lucas plant was identified that could be used to establish background concentrations for the shallow zone
of aquifer on the east side of Hilliards Creek. The analytical data for ground water samples collected from
monitoring well (MW) 14, indicate that the ground water contamination from the Lucas plant has not
contaminated the ground water at MW-14. Although MW-14 is located on the Lucas plant in areas of known
contamination, the well is used to establish background concentrations for the shallow zone of the aquifer on
the east side of Hilliards Creek because analytical data indicate that operations at the Lucas plant have not
released hazardous substances to the well, as documented in the sections below. MW-14 is located north of
Building 67 (Ref. 31, Figure 3-2). Ground water samples were collected from MW-14 during four separate
sampling activities (Ref. 31, Table 3-1, p. 3). As documented in the section below, during each sampling
activity, no significant concentrations of hazardous substances were detected in the ground water samples.

MW-20 is also used to establish background SVOC and VOC concentrations for the shallow zone of the
aquifer on the east side of Hilliards Creek for the 1993 sampling activity. The monitoring well is screened
in the shallow zone of the aquifer and is located on the northwest side of Building 55 (Ref. 31, Table 4-1, p.
2 and Figure 3-2). The ground water samples collected from MW-20 were analyzed for SVOCs and VOCs
(Ref. 31, Table 3-1). MW-28, located northeast of the Lucas plant, is also used to establish background
concentrations for the shallow zone of the aquifer on the east side of Hilliards Creek (Ref. 31, Figure 3-2).
MW-28 is screened in the shallow portion of the aquifer (Ref. 31, Table 4-1, p. 2). Ground water samples
were collected from the well in 1993 and analyzed for SVOCs and VOCs and in 1995 and analyzed for
inorganic compounds (Ref. 31, Table 3-1).

Other background ground water samples for the shallow zone of the aquifer were collected from 47
Hydropunch™ sampling locations (SGW-200 sample identification sequence), excluding SGW-278, SGW-
280, and SGW-300, for screening analyses. Thirty-nine shallow ground water-screening samples were
collected from the Hydropunch™ locations and analyzed for BTEX. Analytical data for the SGW sampling
locations SGW-200; SGW-204; SGW- 210; and SGW-286 are presented to illustrate that the BTEX
compounds detected in the shallow zone of the aquifer on the east side of Hilliards Creek are not migrating
from a source northeast of the Lucas plant (ground water flows from the northeast to the southwest) (Ref. 31,
p. 4-7, Figure 4-7). The Lucas plant is the only potential source of the BTEX ground water contamination.

MW-16 is used to establish background concentrations for shallow zone of the aquifer on the west side of
Hilliards Creek and is located in the area of Tank Farm B (Ref. 31, Table 3-1, p. 2, and Figure 3-2). Although
Tank Farm B (Source 4) is a potential source of ground water contamination, analytical results for samples
collected from MW-16 have not indicated significant concentrations of hazardous substances (Ref. 31, Table
4-9). The only contaminant detected in ground water samples collected from MW-16 at significant
concentrations is lead, up to 10 j^ig/L. This may reflect ground water contamination from Tank Farm B (Ref.
31, Table 4-9).

Two monitoring wells are used to establish background concentrations for the deep zone of the aquifer, MW-
32 and MW-34 (Ref. 31, Table 3-1, p. 2). MW-32 is located on the east side of Hilliards Creek in the eastern
section of the Lucas plant, near the gasoline station, upgradient of the source areas. MW-34 is located on the
east side of Hilliards Creek in the far northeastern portion of the Lucas plant upgradient of source areas.
Monitoring well locations are shown in Reference 31, Figure 3-2.

Based on similar screened intervals, dates of collection, analytical and collection procedures, and analytical

180


-------
GW to SW Component - Observed Release to Ground Water

parameters, the samples collected from MW-14, MW-16, MW-20, MW-28, MW-32, and MW-34 are
considered to be adequate background samples. Ground water samples collected from Hydropunch™
background sampling locations are presented to illustrate that no source of BTEX contamination is located
northeast of the Lucas plant. Although the ground water samples were collected for screening purposes only
and were not collected from completed monitoring wells, presentation of these background concentrations
provides additional evidence that the Lucas plant is the source of BTEX contamination in groundwater.

There are numerous instances where analytical results from the analysis of the samples are not provided in
the RI summary of detections tables. For example, in the years 1999 and 2000, ground water samples were
collected from MW-32 and analyzed for VOCs and SVOCs (Ref. 31, Table 3-1). Analytical results for
samples collected on those dates are not provided in the summary of detections tables presented in the RI
(Ref. 31, Table 4-11). It is likely that the results were notrecorded because no hazardous substances were
detected in the ground water samples collected on those dates.

No background ground water sample analytical results were identified in the RI for years 1999 and 2000.
Therefore, data for groundwater samples collected from the date closest to the years 1999 and 2000 are used
to establish background concentrations. In many cases, background ground water samples were collected
a year or more before the release ground water sample was collected. Although the background samples used
were collected up to a year or more before the release ground water samples, the background samples used
are considered adequate because the hazardous substances detected in the release ground water samples are
not naturally occurring, are established as being present in the shallow aquifer underlying the Lucas plant,
and are at least partially attributable to the Lucas plant.

The construction details for the background monitoring wells are summarized in Table 28. As shown in
Table 28, MW-32 and MW-34 are screened at a greater depths than MW-14, MW-16, MW-20, and MW-28.
MW-14, MW-20, andMW-28 are used to establish background conditions for the shallow zone ofthe aquifer
located on the east side of Hilliards Creek. MW-16 is used to establish background conditions for the
shallow zone of the aquifer on the west side of Hilliards Creek. MW-32 and MW-34 are used to establish
background conditions for the deep zone of the aquifer on the east side of Hilliards Creek. Background
ground water samples are compared to release ground water samples collected from monitoring wells
screened within the same relative interval. Ground water samples collected from Hydropunch™ sampling
locations SWG-200; SWG-204; SWG-210; SWG-212; and SWG-286 are used to illustrate that no BTEX
source is located northeast of the plant on east side of Hilliards Creek. No construction information for
Hydropunch™ wells is available (Ref. 31, p. 3-14).

SGW These samples are not used for documenting background or release concentrations. They are used
to show background concentrations for other shallow ground water monitoring (SGW) locations that
are presented in the release sample tables. The SGW locations are presented to illustrate that BTEX
are not migrating from northeast of the Lucas plant.

Table 29 summarizes the analytical parameters for ground water samples collected from MW-14; MW-16;
MW-20; MW-28; MW-32; MW-34; SGW-200; SGW-204; SGW-210; SGW-212; and SGW-286. The
reference documentation does not describe the analytical methods used to analyze the ground water samples
or the detection limits (Ref. 31, Table 3-1, pp. 4, 8). Table 29 presents the analytical parameters exactly as
they appear in Reference 31, Table 3-1. Table 3-1 of Reference 31 indicates that ground water samples
collected from MW-34 were analyzed for VOCs on February 3, 1999; March, 24, 1999; and January 14,
2000. However, the VOC analytical results for MW-34 are not provided in the summary of detections tables
in the RI report (Ref. 31, Table 4-11). Because the summary of VOC detections for MW-34 is missing from
the RI, MW-32 is used to establish background concentrations for VOCs in ground water collected from

182


-------
GW to SW Component - Observed Release to Ground Water

within the same relative screened interval and dates. Because Table 4-11 of Reference 31 provides only a
summary of detections, it is likely that no VOCs were detected in ground water samples collected from MW-
34 and therefore, no analytical results were provided in Table 4-11 of Reference 31 for MW-34.

The rational or purpose for selecting the locations of the monitoring wells used to establish background
conditions for the Lucas plant is not provided in the RI. The text of the RI does not discuss MW-32 and
MW-34. However, the RI does discuss the purpose for some of the monitoring well locations. The RI
indicates that from August 1991 through January 1992, during Phase I of the RI (Ref. 31, p. 3-3), MW-14
was installed in the ground water seep area to define ground water flow direction and to monitor ground
water conditions (Ref. 31, pp. 3-1, 3-11). Ground water samples were collected from MW-14 and analyzed
for PP VOA+15, PPbase neutral acids (BNA), phenols, lead, barium, and chromium (Ref. 31, p. 3-31). A
list of PP VOA and BNAs is provided in Reference 96. During Phase II of the RI a ground water sample was
collectedfromMW-14 and analyzed for lead (Ref. 31, p. 3-17). According to the RI, ground water samples
were collected from MW-28 for the purpose of characterizing specific water qualify parameters required for
remedial design options (Ref. 31, p. 3-19). The RI also indicates that MW-16 was installed in the vicinity
of the former Tank Farm B during Phase I ofthe RI (Ref. 31, pp. 3-1, 3-3,3-31). Groundwater samples were
collected from MW-16 and analyzed for PP VOA+15, PP base neutral acids (BNA), phenols, lead, barium,
and chromium (Ref. 31, p. 3-31). From June 1993 through October 1993, during Phase II ofthe RI(Ref. 31,
p. 3-3), ground water samples were collected from MW-16 and analyzed for VOC+10, SVOC+20, and lead
(Ref. 31, p. 3-32). From July 1998 through January 2000, during Phase V of the RI (Ref. 31, p. 3-3), ground
water samples were collected from MW-16 to confirm the presence of PCP based on previous analytical
results (Ref. 31, p. 3-33). MW-20 was installed at greater depths in the water table aquifer (Ref. 31, p. 3-15).

The concentrations of hazardous substances detected in ground water samples collected from MW-14; MW-
16; MW-20; MW-28; MW-32; MW-34; SGW-200; SGW-204; SGW-210; SGW-212; and SGW-286 are
summarized in Table 30. In many cases, hazardous substances listed in Table 30 do not appear in the
summary of detections tables (Ref. 31, Tables 4-9, 4-11, and 4-14) used to prepare Table 30. Since the
hazardous substance is not detected, the hazardous substance is not listed in the summary of detections tables.
Not all hazardous substances analyzed for are listed in the summary of detections tables presented in the RI
(Ref. 31, Tables 4-9, 4-11, and 4-14). In some cases, no analytical results are presented in the tables
indicating the none of substances analyzed for were detected. In many cases, a blank space appears in the
cell of the summary of detections tables. A blank cell indicates that the hazardous substance was not
detected. The detection limit followed by the laboratory data qualifier is not used to denote "not detected,"
as is most commonly practiced. The analytical results for the analysis of ground water collected from MW-
28 on August 5, 1993 for SVOCs and VOCs, on September 9,1993 for VOC, and July 14, 1995 for metals
are provided in Table 3-11 (Ref. 31, Table 3-1, p. 3 and Table 4-11, pp. 7,20,26). Because analytical results
are not provided in the summary table, no concentrations of hazardous substances were detected in the
ground water samples. The summary table only provides a summary of detections.

"Adjusted concentration: The benzene, 1,2-dichloroethene (total), and pentachlorophenol concentrations
qualified with a "J" data qualifier are adjusted in accordance with Reference 81. The reason for the "J"
qualifiers is unknown; therefore, the samples are conservatively adjusted to reflect an unknown bias. The
concentration is adjusted by multiplying the concentration by the appropriate adjustment factor (Ref. 81,
Exhibit 2). The adjustment factor for benzene is 1.64,1,2-dichloroethene (total) is 10, and pentachlorophenol
is 10.12 (Ref. 81, p. 15).

No analytical results are presented in Table 4-11 for ground water samples collected from MW-28 on August
5, 1993 for VOC and SVOC analysis; on September 9, 1993 for VOC analysis; and on July 14, 1995 for
inorganic analysis because Table 4-11 provides a summary of detections. Therefore, these substances were
not reported (Ref. 31, Table 3-1, p. 4).

GW to SW Component - Observed Release to Ground Water

Release Samples:

Numerous monitoring wells were installed at the Lucas plant in the areas of the sources during the RI (see
Reference 31, Figure 3-2). The construction details and locations ofthe monitoring wells used to document
an observed release to ground water are summarized in Table 31. The construction details were obtained
from borehole logs in Appendix C of Reference 31. In some instances, borehole logs are not provided in
reference documentation. However, Table 4-1 in Reference 31 provides the screened interval for the
monitoring wells in feet below mean sea level (msl). Concentrations of hazardous substances detected in
the release ground water samples are summarized in Table 32.

*	On some sampling dates, background shallow ground water samples were not collected from the
aquifer. Therefore, the deep background ground water samples are used to establish background
concentrations.

Notes (Continued):

Adjusted concentrations - Concentrations with the data qualifier J, estimated value, are divided by the
adjustment factor value in Reference 81. The reason the data were J qualified is not known. Therefore, the
bias was considered high. For release concentrations that have a high bias, the concentration is divided by
the adjustment factor (Ref. 81, Exhibit 3). The adjustment factors used include ethylbenzene (10), total 1,2-
dichloroethene (10), xylene (10), 4-methylphenol (10), and phenol (3.53) (Ref. 81, pp. 11, 12).

Attribution

Attribution:

The hazardous substances detected in the release ground waters samples are attributable to sources located
on the Lucas plant (see Section 2.4 of this documentation record) and to operations conducted at the Lucas
plant as documented in the introduction section and attribution section (Section 4.0) of this documentation
record.

Lead was used extensively at the Lucas plant (Refs. 13, p. 3; 31, p. 2-3; 60, pp. 6, 8, 10, 12, 22, 26). The
presence of lead within ground water and in Hilliards Creek extending from the Lucas plant to Hilliards Road
indicates that overtime operations at the Lucas plant have released lead to ground water and surface water.
As documented in Section 4.0 of this HRS documentation record, other than waste disposal areas used by
the Lucas plant, no other significant sources of lead have been identified in the Hilliards Creek watershed.
Potential sources of ground water contamination in the area surrounding the Lucas plant are discussed in the
attribution and land use surrounding Hilliards Creek sections (see Section 4.0).

Lead has been detected in soil samples collected from sources on the Lucas plant property, as documented
in the waste characterization section (Section 2.4) of this HRS documentation record, and ground water and
surface water sediment and aqueous samples at concentrations exceeding three times the background
concentration (see Sections 4.1.2.1.1 and 4.2.2.1.1 of this HRS documentation record).

Additionally, lead has been detected in product samples collected from the ground water underlying Source
1 (Refs. 76, pp. 12, 13, 19, 20; 77, p. 82). The product has been observed to discharge into Hilliards Creek
(Refs. 10, pp. 1, 2; 31, pp. 3-3, 3-22; 32, p. 5; 65, pp. 1, 2, 3; 36; 37).

Analytical results for free-phase product samples collected from Source 1 indicated the presence of 2-
methylnaphthalene; 4-chloroaniline; naphthalene; benzene; chlorobenzene; ethylbenzene; and xylene (Ref.
31, Table 4-20 and Section 2.4.1 of this HRS documentation for Source 1). These same hazardous
substances were detected in the observed release samples as documented in Section 4.2 of this HRS
documentation record.

Many of the hazardous substances detectedin the observe release to ground water samples were also detected
in source samples including acetone (Sources 1,2, and 4); benzene (Source 1); benzoic acid (Source 3); 2-
butanone (Sources 1 and 2); carbon disulfide (Sources 1 and 3); chlorobenzene (Source 1); chloroform
(Source 4); 1,2-dichloroethene (Sources 1 and 2); 2,4-dimethylphenol (Source 1); ethylbenzene (Sources 1,
2, 3, and 4); lead (Sources 1, 2, 3, and 4); 2-methylnapthalene (Source 1); naphthalene (Sources 1 and 2);
pentachlorophenol (Source 3); toluene (Sources 1 and 4); and xylene (Sources 1,2, and 4). Refer to Section
2.4.1 of this HRS documentation record for the source sample documentation and Section 4.2 of this HRS
documentation record for the ground water sample documentation.

Some of the hazardous substances detected in the ground water observed release samples were not detected
in the source samples including acenaphthene; 2-chloronaphthalene; cresol; dibenzofuran; 1,1 -
dichloroethane; fluorene; 2-methylnaphthalene; 4-methyl phenol; phenol; styrene; tetrachloroethylene; total
1,2-dichloroethene; 2,4,5-trichlorophenol; and vinyl chloride. However, many of these hazardous substances
can be attributed to operations conducted at the Lucas plant. PAHs, such as acenaphthene and fluorene are
common constituents of petroleum products such as was used at the Lucas plant (Refs. 10, p. 9; 105, pp. 2,
4). Cresols are used in paint (Ref. 107, p. 75). 1,2-Dichloroethane is used for varnish and finish removers

Actual Human Food Chain Contamination

Although aqueous and sediment samples document an observed release to the Hilliards Creek, actual
food chain contamination is not scored because no fisheries are documented within the areas of the
observed release (Ref. 1, Section 4.2.3.3).

4.2.3.3.1 Food Chain Individual

No hazardous substance having a bioaccumulation factor value of greater than 500 was detected in both
the observe release to ground water and in the observed release to surface water. Lead was the only
hazardous substance detected in both the observed release to surface water and groundwater migration
pathways. The food chain individual factor is assigned a value of 0 (Ref. 1, Section 4.1.3.3.1).

GW to SW Component/Environmental - Hazardous Waste Quantity

4.2.4.2.2 Hazardous Waste Quantity

The source HWQ values for each of the four sources is greater than zero. As documented in Section
4.1.4.3, wetlands are subject to Level I and II concentrations; therefore, a default value of 100 is assigned
for the HWQ value (Ref. 1, Section 2.4.2.2, Table 2-6).

237

Hazardous Waste Quantity Factor Value: 100


-------
GW to SW/Environmental - Waste Characteristics Factor Category Value
4.2.4.2.3 Waste Characteristics Factor Category Value

The waste characteristics factor category value is determined by taking the product of the highest
ecosystem toxicity/mobility/persistence factor value for lead and the HWQ value and multiplying the
product by the highest ecosystem bioaccumulation factor value for lead (Ref. 1, Section 4.1.4.2.3).

1,000 x 100 = 100,000

Ecosystem toxicity/persistence factor value

100,000 x 50,000 = 5 x 10"

(Ecosystem toxicity/persistence X hazardous waste quantity)

Waste Characteristics Factor Category Value: 180

(Ref. 1, Table 2-7)

GW to SW Component/Environmental - Targets

4.2.4.3 ENVIRONMENTAL THREAT - TARGETS
Level I Concentrations

The Level I concentrations for ground water to surface water migration component are the same
concentrations documented in Section 4.1.4.3 for the surface water overland flow component. Lead was
documented in both an observed release to groundwater and to surface water as documented in Section 4.0
of this documentation record (Ref. 1, Section 4.2.1.3 and Section 4.2.1.4). Because the surface water
sampling locations documenting Level I concentrations and the PPE to surface water from overland flow and
groundwater are the same, the Level Itargets are the same. See Section4.1.4.3 for the Level I concentrations.

-------
GW to SW Environmental - Level I Concentrations

4.2.4.3.1 Sensitive Environments
4.2.4.3.1.1 Level I Concentrations
Sensitive Environments

Sensitive environments other than wetlands have not been identified within the 15-mile downstream target
distance.

Wetlands

The wetland areas were identified from Reference 93, Wetland Inventory Map. The wetland is a palustrine
forested broad-leaved deciduous and needle-leaved evergreen, and palustrine scrub/shrub and emergent
wetland (Ref. 93). The sampling locations identified in the Level I Concentrations section above are within
this wetland (Ref. 97). The wetlands subject to Level I concentrations are those wetlands located between
PPE-1 and the most distance downstream Level I sampling location (HC-SW-39) (Ref. 1, Section 4.1.1.2).

The total length of wetlands from PPE-1 to the most downstream sampling location (HC-SW-39) containing
Level I concentrations is estimated to be 5,708 feet (Refs. 93; 97). Since wetlands are located on both sides
of Hilliards Creek, the total length of wetlands subject to Level I concentrations is two times 5,708 feet or
11,416 feet or 2.16 miles (Ref. 1, Section 4.1.4.3.1.1). The wetland frontage is summarized in Table 25.
The wetland frontage is summarized in Table 37.

The wetland ratings value for 2.16 miles is obtained from Reference 1, Table 4-24 and is 78.

Level I Wetland Value: 50
(Ref. 1, Table 4-24)

For wetlands subject to Level I concentrations, the wetland value (75) is multiplied by 10 (Ref. 1, Section
4.1.4.3.1.1).

Level I Concentrations Factor Value: 750 (Ref. 1, Section 4.1.4.3.1.1)

GW to SW Environmental - Level II Concentrations

4.2.4.3.1 Sensitive Environments
4.2.4.3.1.1 Level II Concentrations
Sensitive Environments

Sensitive environments other than wetlands have been not been identified within the 15-mile downstream
target distance.

Wetlands

The wetland length subj ect to Level II concentrations is located between surface water sampling location HC-
SW-39 (most distance Level I concentration) and sediment sampling location HC-SD-43, the most distant
Level II sediment sampling location. That length is estimated to be 778 feet or 0.15 mile as measured on Ref.
97 (Refs. 93; 97) and includes the length of wetlands on both the north and south banks of Hilliards Creek
(Ref. 1, Section 4.1.4.3.1.1). The Level II wetland frontage is summarized in Table 38.
