SECTION I
INTRODUCTION
Superfund was created by Congress in 1980 with
the passage of the Comprehensive
Environmental Response, Compensation, and
Liability Act of 1980 (CERCLA). On October 17,
1986, the Superfund Amendments and
Reauthorization Act of 1986 (SARA) was enacted.
SARA reflected EPA's experience in
administering the complex Superfund program
during its first six years and made several
important changes and additions to the program.
SARA stressed the importance of permanent
remedies and innovative treatment technologies
in cleaning up hazardous waste sites; required
Superfund actions to consider the standards and
requirements found in other Federal and State
environmental laws and regulations; provided
new enforcement authorities and settlement
tools; increased State involvement in every phase
of the Superfund program; increased the focus
on human health problems posed by hazardous
waste sites; and encouraged greater citizen
participation in making decisions on how sites
should be cleaned up.
The Superfund remedial program has modified
its approach to site cleanups to reflect the
mandates in CERCLA, as amended by SARA.
For example, Section 121 of CERCLA mandates
the selection of a remedial action that is
protective of human health and the environment,
complies with applicable or relevant and
appropriate Federal and State requirements
(ARARs), is cost-effective, and utilizes permanent
solutions and alternative treatment technologies
or resource recovery technologies to the
maximum extent practicable. In addition,
CERCLA includes a preference for remedies that
employ treatment that permanently and
significantly reduces the volume, toxicity, or
mobility of hazardous wastes as a principal
element.
The Records of Decision (RODs) highlighted in
this annual report, document compliance with
SARA mandates for the remedial program in FY
1991. Each ROD discusses the remedy decision
for a site or operable unit, certifies that the
remedy selection process has followed the
requirements of CERCLA and the National
Contingency Plan (NCP), discusses the major
technical components of the remedy, and
provides the public with a consolidated source of
information about the site. Once the Regional
Administrator or the Assistant Administrator of
the Office of Solid Waste and Emergency
Response signs the ROD, it is made available for
information purposes and placed in the
administrative record for the site. Nine hundred
forty-five (945) RODs have been signed since the
Superfund program began (see Exhibit 7).
FY 1991 RODs
One hundred eighty-three (183) RODs and
thirteen (13) ROD Amendments, including
Fund-lead, Enforcement, and Federal Facility
RODs were signed during FY 1991. The data in
this annual report are based on these 196 RODs
and ROD Amendments; for clarity, these are
collectively referred to as RODs throughout the
remainder of the report. One hundred forty-one
(141) of the 196 RODs addressed source control
remediation, and 46 RODs addressed ground-
water-only remediation. The remaining 9 RODs
were no action/no further action remedies. Of
the total 141 source control RODs, 114 addressed
a final source control remedy, and 27 addressed
an interim source control remedy. Eighty-five
(85) of the 141 source control RODs selected both
source control and ground water remediation
components.
In keeping with CERCLA Section 121 and the
NCP program expectations to treat highly toxic,
highly mobile wastes and contain low level
wastes or large volumes of waste, 'treatment
technologies' were used for 99 (70%) of the 141
source control remedies (see Exhibit 3A).
'Treatment technologies' are those selected
source control technologies listed at the top of
Exhibit 2, as opposed to other types of treatment.
In a further breakdown, source control treatment
technologies plus the other types of treatment,
were selected for 77 (68%) of the 114 'final'
source control RODs (see Exhibit 3B). A
historical overview of the increase in treatment
-------
selected for source control and 'final' source
control RODs since 1982, is shown in Exhibits 3A
through 3C. Exhibits 3A and 3C show the
percentages of Superfund source control
remedies which have chosen all types of
treatment, while Exhibit 3B shows the
percentages of 'final' source control remedies
since 1987 that have used treatment technologies.
It was not until after SARA, in 1986, that more
data on the 'final' source control remedies
became available for comparison.
Exhibits
Exhibits 1 through 13 summarize various data
from the 196 FY 1991 RODs, and similar data
comparisons for all RODs since FY 1982.
Exhibit 1 provides an overview of the types of
remedial action selected for all FY 1991 RODs.
Exhibit 1A provides the same overview for all
RODs FY 1987 - FY 1991.
Exhibit 2 provides a quantitative summary of
remedial action components by the number of
occurrences in RODs. Occurrences means the
count of one or more technologies, which may be
associated with a remedial action described in
the ROD. For example, a ground water remedy
may consist of air stripping, aeration, and carbon
adsorption, as part of a treatment train, which
would consist of three occurrences. This exhibit
demonstrates that occurrences of the use of
treatment technologies (146) for the 141 source
control remedies exceeded that of containment
only remedy occurrences (35) by a factor of four.
Of the 146 occurrences of source control
treatment technologies, immobilization (35) and
in-situ vacuum/vapor extraction treatment (34)
were selected most frequently, followed by
thermal destruction/incineration (24).
Exhibit 3 compares the number of FY 1991
source control RODs employing 'containment' as
a primary component of the remedy, with RODs
employing 'treatment' as a principal component.
Exhibit 3A shows the percent of all source
control RODs that used some type of treatment,
as a percent of all the source control RODs for
each year. For example, there were 141 source
control RODs in FY 1991, and of those 141
RODs, 99 (70%) used 'treatment technologies'.
The remainder of the source control RODs in
FY 1991 used containment or other actions for
the source control remedy. Exhibit 3B shows the
percent of 'final' source control RODs, which
employed some type of treatment. Exhibit 3B
shows that in FY 1991, 77 (68%) of the 'final'
source control RODs (114) used treatment
remedies. The remainder (37) of the 'final'
source control RODs in FY 1991 used other types
of remedies. Exhibit 3C shows out of all the
RODs each year, what percent of remedies have
used treatment technologies for source control,
versus the percent utilizing containment only
and other actions. Exhibits 3 through 3C
indicate that the use of treatment for Superfund
remedy selection has increased and remained
about constant for the past four years between
FY 1988 and FY 1991.
Exhibit 4 illustrates the occurrences of treatment
technologies in FY 1991 source control remedies
by treatment technology. Separation/recovery
was the main treatment technology category,
followed by destruction/detoxification
technologies. Exhibit 4A shows the same data
for all occurrences of technologies since FY 1982.
Exhibit 5 shows the total number of treatment
occurrences (270) for ground water remedies in
FY 1991 RODs. The majority of ground water
treatment occurrences were physical/chemical
treatment technologies (83%), including air
stripping, carbon adsorption, and precipitation.
Biological treatment was employed in 2% of the
treatments, and the remaining 15% of ground
water remedies used other technologies to
restore ground water to its beneficial uses within
a reasonable timeframe.
An index of site remedies for FY 1991 is
provided in Exhibit 6, which contains RODs
grouped by the specific type of source control
and/or non-source control remedy selected. To
assist in understanding the technology data
presented in Exhibits 1 through 6, a description
of each source control and ground water
treatment occurrence is provided in Section V of
this Volume.
-------
Historical Overview FY 1982-1991
The passage of SARA strengthened and extended
the Superfund program while maintaining the
overall framework for implementation. New
requirements under CERCLA, as amended by
SARA, were intended to ensure protective clean-
up standards, permanent remedies, and the use
of alternative technologies where applicable. A
historical overview of FY 1982 - FY 1991 RODs is
provided in Exhibits 7 through 11 to show
annual progress in achieving these statutory
mandates.
Exhibit 7 depicts the number of RODs signed per
fiscal year. Exhibit 8 is a quantitative overview
of the occurrences and type of treatment
technologies which have been selected in the 99
source control treatment technology RODs.
Exhibits 10 and 11 provides a list of individual
sites where these treatment technologies were
selected.
Comparative data on the number of RODs and
number of occurrences of treatment technologies
and 'innovative' technologies selected for source
control RODs (FY 1987 - FY 1991) are presented
in Exhibit 9. These data demonstrate that there
has been: (1) an increase in the percentage of
RODs selecting treatment as a principal remedy
for source control, and (2) an increase in the
percentage of innovative treatment technologies
selected.
Exhibits 12 and 13 illustrate and list the
information for FY 1991 treatment train RODs,
i.e., RODs which employ a sequence of treatment
technologies to address a single medium or
constituent. Exhibit 14 provides a comparison of
FY 1982 - FY 1991 ROD data on remedial action
costs.

RECORD OF DECISION ABSTRACTS
ROD summaries are arranged alphabetically by Region; however, not every State may
have had a ROD signed in FY 1991.
Each ROD summary presented in this section consists of the following:
ROD Abstract - summarizing site location and background information,
contaminated media, key contaminants, selected remedial action, and
present worth or capital costs and O&M costs.
Performance Standards or Goals - describing qualitative/quantitative
cleanup criteria.
Institutional Controls - describing ordered site restrictions.
Keywords - highlighting treatment technologies, contaminated media, key
contaminants, and major keyword categories for the RODs. A list of RODs
by keywords is presented in the last section of this document.
A list of RODs signed in FY 1991 follows the abstracts in this section.

REGION 1
FY91 ROD ANNUAL REPORT ABSTRACTS
DOVER MUNICIPAL LANDFILL, NH
September 10,1991
SITEHISTORY/DESCRIPTION:
The 55-acre Dover Municipal Landfill site is an
inactive landfill in Dover, Strafford County, New
Hampshire. Land use in the area is rural-
residential and recreational. The site overlies
both an upper and a lower aquifer that are
separated by impermeable clay. Significant
nearby surface water bodies include the Bellamy
reservoir located 2,000 feet south of the site,
which supplies drinking water for local
municipalities; the Calderwood well, which
supplies drinking water for the City of Dover,
and is located approximately one-half mile north
of the landfill; and the Cocheco River, which
runs approximately 500 feet east of the landfill.
A portion of the site lies within the 100-year
floodplain of the Cocheco River, and four
wetland systems are in the vicinity of the site.
From 1960 until 1979, the landfill accepted
municipal and industrial wastes including
drummed materials and liquid wastes. Landfill
disposal practices included trenching, burning,
and fill and cover methods. Between 1980 and
1982, the facility was capped and closed, and a
drainage channel was excavated around the
landfill to intercept leachate. In 1981, VOC
contamination was found in private residential
wells screened in the upper aquifer in the
vicinity of the landfill. Further analyses
identified two contaminant plumes, one
migrating to the south and the other moving to
the east. This ROD addresses both source
control and management of migration of
contaminated ground water, as a final remedy.
The primary contaminants of concern affecting
the soil, sediment, sludge, debris, and ground
water are VOCs including benzene, PCE, TCE,
toluene, and vinyl chloride; other organics; and
metals including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and consolidating approximately
300 cubic yards of sediment from the drainage
channel, and depositing the material into the
landfill prior to capping; recontouring and
capping the landfill with a multi-media cap with
a passive venting system for methane gas;
pumping and onsite treatment of the southern
plume ground water and leachate using aeration
for VOC removal, carbon adsorption to remove
other organics, and flocculation, coagulation, and
precipitation, followed by discharge of the
treated water onsite to surface water or offsite to
the Dover POTW; disposing of residual sludge
offsite; constructing a clean ground water
diversion system upgradient of the site; natural
attenuation of the eastern plume ground water;
constructing a surface water run-on/run-off
diversion system; conducting long-term ground
water monitoring; and implementing
institutional controls including deed and ground
water use restrictions. If it is determined that
the selected ground water treatment remedy for
the southern plume is not effective, a
contingency remedy that utilizes precipitation
and air stripping will be implemented. The
estimated present worth cost for this remedial
action is $24,155,700, which includes an annual
O&M cost of $157,680 for 10 years and an annual
cost for ground water monitoring of $721,600 for
30 years.
PERFORMANCE STANDARDS OR GOALS:
Sediment in areas where arsenic levels are above
50 mg/kg will be excavated and consolidated
under the landfill cap. Ground water interim

GROVELAND WELLS, MA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 850-acre Groveland Wells site is a municipal
well field in Groveland, Massachusetts. Land
use in the area is residential, industrial, and
commercial. The site is bounded to the north by
the Merrimack River; to the west by the
Haverhill Municipal Landfill, which is another
Superfund site; and to the south and east by
mixed land use areas. The site is underlain by a
surfical unconsolidated aquifer, which is a source
of ground water for the well field, and a deeper
bedrock aquifer. Both a current and a former
municipal water supply well are located within
the site boundaries. Johnson Creek, including its
associated wetlands, flows across the site, and
portions of the site lie within the 100-year
floodplain of the Merrimack River. In 1979,
elevated levels of TCE were discovered in the
onsite water supply wells, resulting in the
closure of the wells, development of alternate
water supplies, and investigations by EPA. An
initial remedial measure (IRM) by EPA in 1985
provided an alternate water supply by installing
a carbon adsorption unit on one of the onsite
water supply wells. EPA investigations
'dentified three likely sources of contamination:
the A.W. Chesterton Company, currently being
remediated under RCRA corrective action and
closure activities; the Haverhill Municipal
Landfill, which has been addressed as a separate
CERCLA action; and the Valley Manufactured
Products Company (Valley), a screw machine
products manufacturer and finisher. From 1963
to 1974, Valley operations involved the release of
UP to 3,000 gallons of waste oil and solvents,
Deluding TCE, to the soil either from a major
Ť*k of 500-700 gallons of TCE that escaped from
an underground storage tank, other onsite spills
Or leaks into the subsurface disposal systems,
and the use of waste oil containing TCE as a
defoliant. A 1988 ROD provided for removal of
source contamination from the Valley property
using vacuum extraction, and installation of a
ground water recovery, treatment, and
reinjection system to treat VOC-contaminated
ground water beneath the property. The State
also required Valley to install a ground water
pump and treatment system using air stripping
to intercept the plume at Mill Pond, an onsite
man-made water body. This ROD addresses
management of migration of contamination in
the surfical and bedrock aquifers extending from
the valley site, as a final remedy. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCE,
and toluene; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and treatment of ground water using
an inorganics removal system consisting of
equalization/aeration, flocculation, coagulation,
sedimentation, and filtration; disposing of the
resulting sludge offsite; further treating ground
water using ultraviolet light and oxidation to
remove VOCs; discharging the treated water
onsite to Johnson Creek; monitoring ground
water, surface water, and sediment; and
implementing institutional controls including
deed and ground water use restrictions. The
estimated present worth cost for this remedial
action is $8,900,000, which includes an annual
O&M cost of $333,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Interim ground water clean-up levels are based
on the more stringent of Federal MCLs or
non-zero MCLGs, or State MCLs. Chemical-
specific ground water goals include benzene
5 ug/1 (MCL), PCE 5 ug/1 (MCL), TCE 5 ug/1
(MCL), toluene 1 mg/1 (MCL), arsenic 50 ug/1
(MCL), and chromium 50 ug/1 (MCL). The
clean-up level for lead, 15 ug/1, is based on EPA
Superfund Policy. When all interim levels are

IRON HORSE PARK, MA
June 27,1991
SITE HISTORY/DESCRIPTION:
The 552-acre Iron Horse Park site is an active
industrial complex and railyard with a long
history of activities that have resulted in
contamination of soil, ground water, and surface
water in North Billerica, Massachusetts. The site
includes open storage areas, landfills, and
lagoons. This ROD addresses the onsite 60-acre
landfill, known as the Shaffer Landfill, that was
used for disposal of residential and commercial
solid waste from 1946 until its closure in 1986.
The Shaffer Landfill is surrounded by wetlands
and lies within the 100-year floodplain of
Middlesex Canal and Content Brook, which
border the site to the east and south,
respectively. Land use outside the surrounding
wetlands areas is predominantly industrial and
residential. As a result of State investigations in
1980, EPA identified onsite contamination in
ground water, surface water, and soil; and the
presence of asbestos. In 1984, EPA, under its
removal authority, covered an onsite asbestos-
contaminated landfill. After further
investigation, EPA divided the site into operable
units (OUs) to facilitate remediation. A 1988
ROD addressed the B&M Lagoon site as OU1,
which includes the contaminated waste lagoons
located on another portion of this site. This
ROD addresses OU2, final remediation of the
Shaffer Landfill, including leachate and ground
water. A future ROD will address surface water
contamination as part of OU3. The primary
contaminants of concern affecting the landfill
materials, ground water, and air are VOCs
including benzene, TCE, toluene, and xylenes;
other organics including PAHs; and metals
including arsenic and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
reconstructing the 60-acre existing landfill cap;
maintaining the cap, the existing surface
drainage system, and the existing landfill gas
collection/flare system; constructing, operating,
and maintaining a leachate collection system;
treating and disposing of leachate offsite;
monitoring ground water, surface water, and the
gas collection/flare system; and implementing
institutional controls including deed and ground
water use restrictions. The estimated present
worth cost for this remedial action is $12,553,524,
which includes a present worth O&M cost of
$3,541,426 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Interim chemical-specific ground water clean-up
goals are based on SDWA MCLs, and include
arsenic 50 ug/1 (MCL), benzene 5 ug/1 (MCL),
and TCE 5 ug/1 (MCL).
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
imposed on the property to prevent the use of
the aquifer as a drinking water source and to
ensure site activities will not compromise the
integrity of the landfill cap.

MOTTOLO PIG FARM, NH
March 29, 1991
SITE HISTORY/DESCRIPTION:
The 50-acre Mottolo Pig Farm site is in
Raymond, New Hampshire. Surrounding land
is primarily rural residential and undeveloped.
The site includes a wooded area, an inactive
piggery area comprised of several structures, a
building drum disposal area, and wetlands. An
onsite brook (Brook A) originating in the
wetlands discharges into the Exeter River. Prior
to 1975, a piggery operation was located onsite.
From 1975 to 1979, the owner disposed of 1,600
drums and pails containing hazardous wastes in
a disposal area north of the piggery building,
and subsequently filled in the area. In 1979, the
State identified onsite buried drums some of
which were crushed and leaking. Consequently
in 1980, EPA began excavation and staging of
these drums. From 1981 to 1982, EPA removed
and characterized drummed waste, then
transported the waste offsite along with 160
cubic yards of contaminated soil, drum parts,
and plastic sheeting. The area was then
regraded and seeded. This ROD addresses
contaminated onsite soil, debris, and the
associated ground water plume. The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including TCE,
toluene, vinyl chloride, and xylenes; and metals
including arsenic.
1ELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing a ground water interceptor trench
upgradient of the former drum disposal area to
reduce migration of contaminants and facilitate
treatment of contaminated soil; capping the
drum disposal and southern boundary areas
with temporary waterproof caps to improve
treatment efficiency; treating approximately
3,4004,000 cubic yards of VOC-contaminated soil
at these areas using in-situ vacuum extraction
and activated carbon to control off-gases,
followed by onsite or offsite carbon regeneration
and disposal; allowing the contaminated ground
water plume to be restored through natural
attenuation; monitoring ground water and
surface water; and implementing institutional
controls including deed and ground water use
restrictions, and site access restrictions such as
fencing. The present worth cost for this remedial
action is $690,000, which includes a present
worth O&M cost of $280,000.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up levels were established to protect
ground water from soil leachate. Ground water
interim clean-up levels were based on Federal
SDWA MCLs and MCLGs, or State Health
Advisory Levels. The estimated time frames for
the restoration of the overburdened ground
water affected by the drum disposal area soil
and the bedrock ground water affected by the
southern boundary soil to acceptable levels by
natural attenuation are 6 years and 2 years,
respectively.
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented onsite.

NYANZA CHEMICAL, MA
September 23,1991
SITE HISTORY/DESCRIPTION:
The 35-acre Nyanza Chemical site is a former
dye manufacturing facility in Ashland,
Middlesex County, Massachusetts. Land
adjacent to the site is used for industrial
residential, commercial, and recreational
purposes. Wetlands are located to the north and
east; woodlands lie to the south, southeast, and
west; and the Sudbury River is 700 feet north of
the site. The site overlies an unconsolidated
glacial aquifer, which has been affected by site
activities. The study area for this ground water
operable unit is larger than the site and consists
of up to 395 acres. From 1917 to 1978, the
property was occupied by several companies
involved in manufacturing textile dyes, dye
intermediates, inorganic collodial solids and
acrylic polymers. Starting in 1917, several types
of wastes were disposed of in various onsite
locations including Megunko Hill, an unsecured
landfill/disposal area in the southern portion of
the site, and wetlands areas to the east and
northwest. Wastes included process wastewater,
chemical sludge, solid process wastes in drums,
solvent recovery distillation residue in drums,
off-specification products, and un-recyclable
process chemicals including phenol,
nitrobenzene, and mercuric sulfate. The dye
waste stream and wastewater were discharged to
an onsite concrete "vault" or settling basin
adjacent to the main processing building. The
liquid occasionally overflowed through a pipe
into the wetlands and to surface water. In the
1960's or 1970's, the vault was removed from
service, and subsequently was filled in with
sludge and covered over with fill. In 1970, a
State investigation linked the site to mercury
contamination in the nearby Sudbury River. A
1985 ROD addressed soil and wetland excavation
at nine localized areas of contamination;
solidification of water-bearing excavated sludge,
sediment, and soil; and placement, capping, and
consolidation of those materials left in place on
Megunko Hill, as Operable Unit 1 (GUI). In
addition, a diversion trench was constructed on
the side of Megunko Hill to divert surface water
flow, and lower the ground water table around
Megunko Hill. In 1985, the State constructed
fencing along a road embankment, placed one
foot of clean fill over an area to prevent direct
contact, and culverted surface water through a
neighboring property under an Interim Response
Measure. In 1987, under an EPA removal action,
655 tons of soil adjacent to the vault were
removed, 309 tons were incinerated, and 356 tons
of soil were transported offsite to an approved
landfill. In 1988, EPA solidified onsite 2,000 tons
of sludge from the vault and disposed of the
sludge at an offsite RCRA landfill facility. This
ROD addresses management of migration as
OU2, and constitutes an interim remedy
designed to treat the highest ground water
contamination and to collect additional data
achieving cleanup objectives. A subsequent
ROD will address uncontrolled wastewater
discharges to the Sudbury River and its
tributaries. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, PCE, TCE, and toluene; other
organics; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes constructing extraction wells at the
northern border of the site; constructing a
ground water treatment plant that utilizes
precipitation and filtration to remove inorganics,
and ultraviolet oxidation or biological treatment
as well as carbon adsorption to remove organics,
pumping and treating ground water, with onsite
discharge of the treated water to surface water;
performing pump tests in the eastern portion of
the plume to determine the need for future
ground water remediation; installing additional
deep bedrock wells to fully define depth and

SAVAGE MUNICIPAL WATER SUPPLY, NH
September 27,1991
SITE HISTORY/DESCRIPTION:
The Savage Municipal Water Supply site is
located in Milford, New Hampshire. The site
and surrounding properties encompass the
Savage Municipal Well, four major industrial
facilities, and two fish hatcheries. Land use
includes residential, agricultural, heavy and light
industrial, and commercial areas. The site is
located within the 100-year floodplain of the
Souhegan River, which is the principal stream
flowing through the site. From the 1940's to the
1980's, process and wastewaters from the
industrial facilities were released untreated to the
ground water or to the surface waters flowing
through the site. In 1983, the State identified
concentrations of several VOCs that were above
drinking water standards in water from the
Savage Municipal Well and water drawn from
the well supplying a nearby trailer park. At the
State's request, EPA conducted a removal action
in 1983. This included temporarily supplying
bottled water to affected residences in the trailer
park, and connecting the residences to the
existing municipal water supply system. This
remedial action addresses potential risks to
future use of the aquifer caused by ground water
contamination at the site, within a 6,000- by
2,500-foot contaminated ground water plume.
This ground water plume was divided into two
zones: the concentrated plume, which contains
the highest concentrations of contaminants; and
the extended plume, which has the remainder of
the contaminated ground water. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCA,
and TCE; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
onsite pumping and treatment of the
concentrated and extended plume areas using air
stripping and ultraviolet oxidation; discharging
the treated ground water onsite; use of natural
attenuation to aid in contaminated ground water
remediation until clean-up levels are met;
implementing ground water, surface water, and
sediment monitoring programs during
remediation; and implementing institutional
controls including deed and ground water use
restrictions. The estimated present worth cost
for this remedial action is $15,500,000, which
includes an annual O&M cost of $1,400,000 for
30 years.
PERFORMANCE STANDARDS OR GOALS:
Interim ground water clean-up levels for
carcinogenic compounds have been set at the
more stringent of MCLs, non-zero MCLGs, or an
excess cancer risk of 10~6- Clean-up levels for
non-carcinogenic compounds have been set at
the non-zero MCLG or an HI*1. Ground water
clean-up levels include benzene 5 ug/1 (MCL),
PCE 5 ug/1 (MCL), TCE 5 ug/1 (MCL), arsenic
50 ug/1 (MCL), chromium 100 ug/1 (MCL), and
lead 15 ug/1 (action). Final protective clean-up
levels will be developed after interim levels have
been attained or the remedy is otherwise deemed
protective.
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented to restrict the use of contaminated
ground water.

SILRESIM CHEMICAL, MA
September 19,1991
SITE HISTORY/DESCRIPTION:
The 4.5-acre Silresim Chemical site is a former
chemical waste reclamation facility in Lowell,
Massachusetts. Land use in the area is
predominantly industrial, although residential
areas are located to the south, east, and northeast
with the closest residences approximately 300 to
500 feet from the site. The nearby residences
obtain their drinking water from a municipal
water supply. From 1971 to 1977, Silresim
Chemical Corporation (SCO used the site for a
chemical waste reclamation facility. The facility's
primary operations included recycling and
reclaiming various chemicals and consolidating
waste for offsite disposal. The facility handled
approximately 3 million gallons of waste per
year including halogenated solvents, oily wastes,
alcohols, metal sludge, and plating and pesticide
wastes. From 1977 to 1978, SCC abandoned the
facility, leaving approximately 1 million gallons
of hazardous waste onsite in bulk tanks and
nearly 30,000 decaying drums. State
investigations revealed evidence of numerous
spills, leakage of drums, discharges to nearby
sewers, and run-off to adjacent property. A
number of EPA and State investigations revealed
contamination of soil and ground water. From
1978 to 1982, the State constructed a fence,
removed liquid waste in onsite drums and tanks,
and constructed berms and absorbent-filled
trenches. From 1983 to 1984, EPA removed all
onsite structures, extended the fence, and placed
a clay cap over the site. This ROD addresses
both onsite and offsite soil and ground water
contamination. The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene, TCE, toluene, and
xylenes; other organics including dioxin, PAHs,
PCBs, and phenols; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing additional perimeter fencing;
placing a low-permeability temporary cover over
areas of contaminated offsite soil; extending and
repairing the existing cap as required;
conducting in-situ vacuum/vapor extraction of
approximately 137,000 cubic yards of
contaminated soil; excavating and stabilizing any
soil with residual contamination after treatment
with vapor extraction, followed by onsite
disposal; backfilling excavated areas with clean
fill; installing a RCRA Subtitle C cap over the
stabilized soil; pumping and pretreatment of
ground water using a phase separation tank to
separate non-aqueous phase liquids (NAPLs),
followed by chemical addition, flocculation,
precipitation, and filtration to remove metals;
offsite disposal of NAPLs and residuals from the
metals removal process; treating residual ground
water using air stripping of heated influent,
thermal oxidation, and aqueous phase carbon
adsorption, followed by offsite discharge of the
treated ground water to the municipal sewer
system or onsite discharge to surface water;
conducting long-term soil, surface water, and
ground water monitoring; and implementing
institutional controls including deed, ground
water, and land use restrictions. The estimated
present worth cost for this remedial action is
$22^00,000, which includes a present worth
O&M cost of $9,263,000.

SULLIVAN'S LEDGE, MA
September 27,1991
SITE HISTORY/DESCRIPTION:
The Sullivan's Ledge site consists of a 12-acre
former quarry site/disposal area and 14.5 acres
of downgradient wetlands areas in New Bedford,
Bristol County, Massachusetts. Land use in the
area is predominantly municipal. The
downgradient portion of the site, which is the
focus of this ROD, includes two wetlands areas:
a 13-acre wooded wetland called Middle Marsh
bordering the Unnamed Stream and a 1.5-acre
wetland area 400 feet upstream from Middle
Marsh called the "adjacent wetlands". In
addition, the site includes portions of golf course
fairways, and associated floodplains and
watershed areas. The entire site lies within the
25- and 100-year floodplains of a tributary of the
Unnamed Stream to the south and the
Apponagansett Swamp to the north. Prior to
1930,12 acres of the site were used as a granite
quarry. From the 1930's to 1970% the City of
New Bedford acquired the property and used
the quarry pits and nearby areas were used for
disposal of hazardous materials including
electrical transformers and capacitors, fuel oil,
volatile liquids, and other industrial wastes.
From 1988 to 1990, several EPA investigations
identified contamination by PCBs and PAHs in
surface and subsurface sediment, soil, and biota;
and VOCs and inorganics in ground water.
Contamination has resulted in part from
contaminated sediment migrating from the
disposal area via the Unnamed Stream and
deposition in Middle Marsh during stream
flooding. A 1989 ROD for the first operable unit
(OU1) addressed source control of the disposal
area and the Unnamed Stream. This ROD
addresses the Middle Marsh as OU2. The
primary contaminants of concern affecting the
soil, sediment, and surface water are VOCs
including toluene; other organics including
PAHs, PCBs, pesticides, and phenols; and metals
including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and dewatering approximately 5,200
cubic yards of contaminated sediment and soil
from portions of Middle Marsh and the adjacent
wetlands; solidifying/stabilizing the excavated
materials as needed to comply with RCRA LDR
rules; treating water extracted from excavated
materials using carbon adsorption, followed by
onsite discharge to the Unnamed Stream; onsite
disposal of the excavated materials beneath the
cap that will be constructed over portions of the
disposal area as part of OU1; restoring affected
wetlands; conducting long-term environmental
monitoring; and implementing institutional
controls to prevent future residential use of
Middle Marsh and the adjacent wetlands. If the
disposal area in OU1 has already been capped
when materials from OU2 are excavated and
ready for disposal, a contingency remedy will be
implemented. This contingency remedy includes
treating the excavated soil/sediment using
solvent extraction, and treating the extracted oil
containing PCBs and other organic chemicals
offsite using incineration; treating residual water
using carbon adsorption; disposing of the treated
sediment/soil at Middle Marsh; restoring
affected wetlands; conducting long-term
environmental monitoring; and implementing
institutional controls to prevent future residential
use of Middle Marsh and the adjacent wetlands.
The estimated present worth cost for this
remedial action is $2,800,000, which includes a
present worth O&M cost of $164,000. The
estimated present worth cost for the contingent
remedy is $7,780,000, which includes a present
worth O&M cost of $164,000.

PERFORMANCE STANDARDS OR GOALS:
Soil, sediment, and surface water clean-up goals
are based on an excess lifetime cancer risk of 10"4
to 10"6 and an HI=1. The sediment/soil clean-up
level for aquatic areas in Middle Marsh is the
interim mean sediment quality criterion of 20 ug
of total PCBs per gram of carbon (ug/Gc). This
will result in interstitial water concentrations
equal to or lower than the PCB ambient water
quality criteria of 0.014 ug/1. The sediment/soil
clean-up level for non-aquatic areas in Middle
Marsh and for the adjacent wetland is total PCBs
15 mg/kg. This will protect mammals from
chronic adverse effects from wetland/terrestial
exposure to contaminated sediment/soil.
INSTITUTIONAL CONTROLS:
Land use or deed restrictions will be
implemented to ensure that Middle Marsh and
the adjacent wetland are limited to recreation
and conservation purposes.

UNION CHEMICAL, ME
December 27,1990
SITE HISTORY/DESCRIPTION:
The 12.5-acre Union Chemical (UCC) site is an
inactive paint stripping solvent manufacturing
and recycling facility in Hope, Knox County,
Maine. Land use in the area is residential, and
a pond is located approximately 300 feet
northeast of the site. The site is bounded on the
east and southeast by Quiggle Brook, which
flows southward for 5 miles before discharging
into Crawford Pond, a drinking water source. A
floodplain and a wetland area exist along
Quiggle Brook at the eastern edge of the site,
and another wetland has been identified to the
south. Site operations, which began in 1967,
included formulating patented solvents for paint
stripping and coating. These products were
manufactured and utilized on the premises in
several onsite buildings. Later operations also
included recycling of used stripping compounds
and solvents from other businesses on a small
scale until 1982, when a fluid-bed incinerator
was acquired. In 1979, State investigations
identified the presence of onsite ground water
contamination. Subsequent private studies in
1981 confirmed the presence of contaminated
ground water in the area between the facilities
and Quiggle Brook. The State issued several
violations to the owner between 1979 and 1984,
and eventually closed the plant in late 1984. At
that time approximately 2,000 to 2,500 55-gallon
drums and 30 liquid storage tanks were
identified onsite. In 1984, the State and EPA
removed the 55-gallon drums and all but two of
the liquid storage tanks. This ROD addresses
remediation of onsite soil, debris, sludge, ground
water, and facilities, and provides for further
evaluation of contaminated offsite soil. The
primary contaminants of concern affecting the
soil, debris, sludge, and ground water, are VOCs
including PCE, TCE, toluene, and xylenes; other
organics including dioxin; metals including
arsenic and lead; and other inorganics including
asbestos.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
decontaminating all onsite facilities including the
still building, production facilities, welding shop,
incinerator complex, concrete pads, the church,
all associated equipment, tanks, above-ground
drums, and buried pipes using high pressure
steam cleaning or another decontamination
technique; collecting and testing all wastewater
resulting from decontamination operations,
draining all contaminated water from sumps,
and treating onsite, if necessary, using UV
light/oxidation or equivalent another treatment
technology; crushing and treating all concrete
from the warehouse pad, structures, floor, and
sumps by low temperature thermal desorption or
an equivalent desorption treatment; backfilling
the treated concrete onsite, if it meets LDR
standards, or removing it offsite for disposal at
a RCRA facility; removing and containing
asbestos from the still building, followed by
offsite disposal; treating any other RCRA
hazardous wastes onsite including dioxin/Iead
scrubber ash, liquids, and sludge from the onsite
equipment prior to offsite disposal by
solidification/stabilization; demolishing the
onsite facilities and associated components;
sampling the debris and removing it offsite to
either a RCRA facility or permitted landfill
depending on testing results; excavating
approximately 10,500 cubic yards of soil from the
unsaturated and saturated zones; treating the
contaminated soil onsite using low temperature
soil aeration or equivalent thermal desorption
technique; conducting treatability studies prior to
full-scale treatment of contaminated soil; treating

clean-up levels using vacuum extraction;
controlling air emissions of organics using vapor
phase carbon adsorption; incinerating or
thermally regenerating the residual carbon
offsite; treating fumes and other particulate
matter collected by the thermal aeration process;
treating soil which does not achieve site-specific
clean-up levels using another approved
technology, or obtaining a RCRA Treatability
Variance; redepositing the treated material onsite
with the other treated soil; filling excavated areas
with clean fill; mixing nutrients with soil prior to
redepositing, and grading and revegetating the
area; constructing additional vacuum enhanced
extraction and monitoring wells; pumping and
treating ground water onsite using UV
light/oxidation or an equivalent destruction
technology, followed by liquid phase carbon
adsorption or an equivalent treatment technology
prior to onsite discharge to Quiggle Brook;
pretreating ground water, if necessary, to remove
inorganics or solids; monitoring air and ground
water; sampling offsite soil, and collecting
meteorological site information to define whether
offsite soil contamination was the result of UCC
operations; and implementing institutional
controls including deed and ground water use
restrictions, and site access restrictions such as
fencing. The present worth cost for this remedial
action ranges from $9,724,000 to $10,654,000,
which includes an O&M cost ranging from
$3,828,000 to $4,757,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS;
Soil clean-up levels are based on an excess
lifetime cancer risk level of less than 10"6 and an
HI<1. Chemical-specific levels for soil include
TCE 100 ug/kg individually, and xylenes
100 mg/kg. Ground water clean-up standards
have been set based on Federal MCLs, MCLGs,
proposed MCLs, or State Maximum Exposure
Guidelines including TCE 5 ug/1 (MCL), total
xylenes 10,000 ug/1 (PMCLG), and toluene 2,000
ug/1 (PMCL).

WESTERN SAND & GRAVEL, Rl
April 16,1991
SITE HISTORY/DESCRIPTION:
The 20-acre Western Sand & Gravel site is a
former liquid waste disposal site on the
boundary of Burrillville and North Smithfield,
Rhode Island. Land use in the area is primarily
semi-rural. Tarklin Brook, which lies within a
wetland immediately to the west of the disposal
area, discharges to a reservoir north of the site.
Residential areas to the west and north of the
site have private wells and use treated ground
water as a source of drinking water. From 1975
to 1979, approximately 12 acres of the site were
used for the disposal of liquid wastes including
hazardous substances and sewage. These wastes
were dumped into 12 unlined lagoons and pits,
and subsequently infiltrated through the porous
soil and into the ground water. As a result of a
fire in one of the pits in 1977, local officials
ordered the owner to remove chemicals from the
site. After the owner failed to comply, a Cease
and Desist Order was issued in 1979, and wastes
were no longer accepted. In 1980 at the request
of the State, EPA removed approximately 60,000
gallons of VOC-contaminated liquid wastes from
the lagoons. In 1982, the State began a ground
water recirculation system to control the spread
of contaminants in the ground water. Remedial
activities for the site have been divided into
three operable units (OUs), addressed by three
RODs. A 1984 ROD provided for installation of
water filters in affected residences, and
subsequent provision for a permanent alternate
water supply (OU1). A 1985 ROD addressed
OU2, which provided site closure activities,
including capping contaminated soil areas with
a RCRA-approved cap, phaseout of the ground
water recirculation system with removal and
offsite disposal of the associated equipment,
evaluation of alternatives for ground water
treatment, ground water monitoring, and
implementing site access restrictions such as
fencing. This ROD addresses contaminated
ground water, which discharges into Tarklin
Brook and the reservoir as OUS. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCE,
toluene, vinyl chloride, and xylenes; other
organics; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
natural attenuation of ground water;
implementing a site monitoring program for
sediment, ground water, and surface water; and
implementing institutional controls to restrict
consumption of ground water. A comparison of
current and historical data indicates that the
magnitude and extent of contamination has
decreased significantly and will continue to
decrease with time as the integrity of the cap is
maintained. Ground water is expected to
achieve interim clean-up levels within 24 to 28
years. However, if this cleanup is proceeding at
an unacceptable rate, active restoration including
pumping and treatment by sedimentation,
filtration, air stripping, and carbon adsorption,
followed by onsite discharge to Tarklin Brook
will be implemented as a contingency remedy.
There are three additional scenarios that
individually may trigger active restoration.
These include: determining that Tarklin Brook is
endangered, that a threat exists from
contamination of the bedrock, or that
institutional controls cannot be implemented
effectively. The estimated present worth cost for
this remedial action is $1,123,952 ($4,039,227 with
active restoration), which includes an annual
O&M cost of $1,041,452 ($2,990,151 with active
restoration) for 24 to 28 years.

PERFORMANCE STANDARDS OR GOALS:
Interim ground water clean-up goals are based
on SDWA MCLs and MCLGs, a 10'6 excess
cancer risk level and an HI=1, or practical
quantification limits. Once all ARAR-based
interim levels have been achieved, a risk analysis
will be performed to develop a cumulative risk
assessment. The cumulative risk of residual
levels must attain a 10"4 to 10"6 risk range for
carcinogens and an HI=1 for non-carcinogens
before these levels will be considered as the final
clean-up levels for any action. Chemical-specific
interim goals for ground water include benzene
5 ug/l (MCL), PCE 5 ug/1 (MCL), TCE 5 ug/1
(MCL), toluene 1 mg/1 (MCL), vinyl chloride
2 ug/1 (MCL), xylenes 10 mg/1 (PMCL), and
lead 5 ug/1 (PMCL).
INSTITUTIONAL CONTROLS:
Institutional controls including regulatory
restrictions, acquisition of affected properties or
ground water rights, and other.restrictions on
property transactions may be implemented, as
needed, to reduce the risk to public health from
consumption of ground water.

A.O. POLYMER, NJ
June 28,1991
SITE HISTORY/DESCRIPTION:
The 4-acre A.O. Polymer site is an active resin
manufacturer in Sparta, Sussex County, New
Jersey. Land use in the area is semi-rural, and
the facility is surrounded by wetlands. The A.O.
Polymer site is one-half mile from Sparta High
School which has an onsite well, and 500 feet
southeast of the Wallkill River, a ground water
discharge area. The ground water in the area is
a current or potential source of drinking water.
From the early 1960's to 1978, Mohawk
Industries operated as a resin production facility
and also reclaimed electronic component
cleaning fluids. In 1978, the A.O. Polymer
Corporation purchased the site, and onsite resin
manufacturing operations continued to utilize
the same storage vessels and laboratories
previously owned by Mohawk Industries. State
investigations in 1978 identified VOC
contamination in local drinking water, and in
1979 the affected residences were connected to
the public water supply. Further, State
investigations in 1978 identified improper waste
handling and storage practices including
disposal of liquid wastes into unlined lagoons;
improper storage of over 800 deteriorating
drums; and buried, crushed, and open drums
containing VOCs and organic compounds. In
1980 and 1981, the State excavated and removed
120 cubic yards of crushed drums and debris,
1,700 cubic yards of associated contaminated soil,
and 1,150 surface drums. In 1982, State
investigations confirmed that these disposal
practices had resulted in the contamination of
potable ground water. This ROD addresses soil
contamination in the former waste lagoon area
and the contaminated ground water plume, and
provides a final remedy for the site. The
primary contaminants of concern affecting the
soil and ground water are VOCs including
benzene, TCE, toluene, and xylenes; and other
organics including PAHs, PCBs, pesticides, and
phenols.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating contaminated soil onsite using vapor
extraction, with control of off-gas emissions
using activated carbon; treating minimal
amounts of liquid condensate with an onsite
ground water treatment unit, or disposing of
liquid condensate offsite along with the spent
carbon; onsite pumping and treatment of ground
water using activated sludge in conjunction with
a powdered activated carbon treatment, followed
by filtration and a carbon polishing treatment;
reinjecting the treated ground water onsite with
a contingency for onsite discharge to surface
water, if necessary; and disposing of residual
sludge offsite. An ARAR waiver may be
necessary if onsite discharge standards to surface
water cannot be met. The estimated present
worth cost for this remedial action is $4,577,000,
which includes an annual O&M cost of $218,000
for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up levels are based on State soil action
levels including total VOCs 1 mg/kg and total
organics 10 mg/kg. Ground water will be
remediated to meet the more restrictive of State
or Federal MCLs.

SITE HISTORY/DESCRIPTION:
The 3.2-acre Applied Environmental Services site
is a former petroleum, gasoline, and solvent
chemical facility in Glenwood Landing, Nassau
County, New York. The site is surrounded by
industrial, commercial, and residential
properties. A tidal wetlands area of Hempstead
Harbor is located to the west of the site. From
1939 to 1972, Texaco Oil Company and,
subsequently, Phillips Petroleum used the site
for bulk storage of petroleum products. From
1974 to 1980, Mattiace Petrochemical Company
leased part of the property, and stored and
distributed chemical solvents onsite. Numerous
spills and releases have occurred onsite,
including a tank truck spill in 1978, which
released 3,000 gallons of toluene that soaked into
the sandy soil and spilled into the adjacent
harbor. From 1980 to 1984, a new tenant,
Applied Environmental Services, blended
various chemical waste materials onsite and
operated a hazardous waste storage facility at
the site. EPA and State investigations in 1984
identified VOCs, metals, and organics in soil,
sediment, ground water, surface water, and air.
Consequently, in 1984, the current site owner,
Shore Realty, was required to remove 255 of the
410 drums containing hazardous waste that were
stored on the property. In 1986 due to the
imminent danger posed by the site, the State
removed approximately 700,000 gallons of
hazardous waste including PCBs from the
facility. This ROD addresses contamination of
soil, ground water, sediment, surface water, and
air as a final remedy. The primary contaminants
of concern affecting the soil, sediment, ground
water, surface water, and air are VOCs including
TCE, toluene, and xylenes; other organics
including PCBs and PAHs; metals including
arsenic, chromium, and lead; and oils.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating contaminated soil using in-situ vacuum
extraction; onsite pumping and treatment of
contaminated ground water using air stripping,
followed by reinjecting the treated ground water
along with nutrients and a chemical source of
oxygen to promote in-situ aerobic biodegradation
of contaminants in ground water and soil;
treating air emissions from the vacuum
extraction and air stripping processes by catalytic
oxidation prior to release to the atmosphere; and
monitoring soil, sediment, ground water, surface
water, and air. The estimated present worth cost
for this remedial action is $4,507,000, which
includes an annual O&M cost of $970,000 for
4 years.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up goals are based on risk-based
criteria. Ground water clean-up goals are based
on State standards. Chemical-specific goals for
ground water include arsenic 25 ug/1, chromium
50 ug/1, lead 25 ug/1, TCE 5 ug/1, toluene
5 ug/1, and xylenes 15 ug/1. For all other
media, clean-up goals are based on applicable
standards for sediment, surface water, and air.

ASBESTOS DUMP, NJ
September 27,1991
SITE HISTORY/DESCRIPTION:
The Asbestos Dump site is composed of four
asbestos disposal areas in Meyersville, Passaic
Township, New Jersey. This ROD addresses two
of the four properties: the 30-acre New Vernon
Road site and the 12-acre White Bridge Road
site. These properties are bordered by the Great
Swamp National Wildlife Refuge, and tracts of
wooded and wetland areas. Land use in the
area is primarily recreational and residential.
From 1968 to 1971, asbestos- containing material
generated by the National Gypsum Company
was disposed of on the New Vernon Road
property in a large depression and in other areas
of the property. From 1970 to 1975, asbestos
material was disposed of on the White Bridge
Road property in what is now a horse-riding
track and in other property areas. In a 1990
investigation, EPA identified high levels of
asbestos contamination in soil at both properties.
Based on this investigation, the Agency for Toxic
Substances and Disease Registry (ATSDR) issued
a Public Health Advisory, and EPA conducted
an immediate removal action at both sites, which
included air and soil sampling for asbestos,
covering areas of visible asbestos contamination
with geotextile fabric, removing any
asbestos-containing material located on the
ground surface for off site disposal, and
restricting site access. A 1988 ROD addressed
another site property, the Millington site, as
Operable Unit 1 (OU1), and provided for
constructing slope protection/stabilization
measures and surface water diversion channels
along and on top of the asbestos mound and
installing security fences and a soil cover. This
ROD addresses the asbestos-contaminated soil on
both the New Vernon Road and White Bridge
Road properties, as OU2. A subsequent ROD
will address the fourth property, the Dietzman
Tract, as OU3, The primary contaminant of
concern affecting the soil is asbestos, an
inorganic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating approximately 37,000 cubic yards of
asbestos-contaminated soil using in-situ
solidification/stabilization and covering the
solidified material with 6 inches of soil;
conducting confirmatory sampling of soil,
sediment, ground water, and surface water;
implementing an air monitoring program; and
implementing institutional controls. The
estimated present worth cost for this remedial
action is $5,700,000, which includes an annual
O&M cost of $43,400.
PERFORMANCE STANDARDS OR GOALS:
The chemical-specific clean-up level for soil at
both sites is the Transmission Electron
Microscopy (TEM) detection limit of 0.5 percent
asbestos.
INSTITUTIONAL CONTROLS:
Institutional controls will be implemented to
restrict future surface and subsurface activities
which could affect the integrity of the treated
waste.

March 29,1991
SITE HISTORY/DESCRIPTION:
The C&J Disposal site is a former industrial
waste disposal area in the Town of Eaton,
Madison County, New York. Land use in the
area is rural and residential. Surface drainage
flows toward a small pond located in a wetland
area 100 feet from the disposal area, and
ultimately drains into Woodman Pond. Located
3,000 feet to the south of the site, Woodman
Pond serves as a backup drinking water source
for the nearby Village of Hamilton. Currently,
12 area residences use ground water as a source
of drinking water. In 1976, C&J Leasing
dumped paint sludge, liquid industrial wastes,
and 75 to 100 drums into an onsite disposal
trench. The trench was subsequently covered
with fill, burying the wastes and drums. In
1989, C&J Leasing conducted an unauthorized
site excavation, which left two large holes and
three stockpiles of soil and waste material in the
trench, as well as scattered crushed drums, cans,
and plastic scrap material. It is believed that
many buried drums were removed offsite during
this excavation. EPA believes that onsite
contaminants are primarily adsorbed or bound in
the 1,250 cubic yards of waste material and soil
and are not presently migrating into the ground
water. This ROD addresses onsite contaminated
soil and debris, and provides a final remedy for
the site. The primary contaminants of concern
affecting the soil and debris are VOCs including
benzene, toluene, TCE, and xylenes; other
organics including PAHs and phenols; and
metals including lead.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
dewatering the trench and treating the water
before recharge, if necessary; excavating
approximately 1,250 cubic yards of contaminated
soil and debris from the disposal trench,
followed by offsite treatment or disposal;
transporting drummed wastes generated during
the field investigation to an offsite RCRA facility
for treatment and/or disposal; backfilling the
trench; revegetating the site; and monitoring
ground water for one year. If all or a portion of
the soil and debris is classified as RCRA
hazardous wastes and require incineration to
meet land disposal restriction (LDR) regulations,
and the wastes are managed prior to May 8,
1992, the soil and debris will be disposed of
offsite without treatment under a National
Capacity Variance. If the wastes require
treatment other than incineration under LDR
regulations, the necessary treatment will be
conducted offsite under a Treatability Variance.
That portion of the soil and debris not classified
as a RCRA hazardous waste will be disposed of
in a RCRA Subtitle-D facility. After May 8,1992,
this ROD provides for a contingency remedy,
which includes offsite thermal treatment of
organic wastes, and treatment and disposal of
inorganic wastes in accordance with LDR
requirements. The estimated present worth cost
for this remedial action, assuming offsite
disposal without treatment, is $672,400, which
includes an annual O&M cost of $86,000.
PERFORMANCE STANDARDS OR GOALS:
Removal of contaminated soil and debris will
ensure that Federal and State regulations for
ground and surface waters are not exceeded.
Clean-up criteria will be based on background
levels found in offsite and native soil samples.
There were no chemical-specific ARARs
provided for soil.

CHEMSOL, NJ
September 20,1991
SITE HISTORY/DESCRIPTION:
The 40-acre Chemsol site is a former solvent
recovery and waste reprocessing facility in
Piscataway Township, Middlesex County, New
Jersey. Land use in the area is predominantly
commercial and residential, with an onsite
marshy area that may be considered a wetlands.
The site overlies a bedrock aquifer that is used
as a regional drinking water source. In addition,
three streams are located onsite that discharge to
nearby Bound Brook. From the 1950's until 1964,
Chemsol, Inc., recovered and reprocessed
solvents and materials received from various
companies through activities such as mixing,
blending, and distillation. The site was closed in
1964 after a series of industrial accidents,
explosions, and fires. In 1978, the site was
purchased by Tang Realty Corporation. In 1984,
as a result of previous accidents, the State
required Tang Realty to investigate site
contamination and to develop a remedial plan.
In 1988, Tang Realty removed 3,700 cubic yards
of PCB-contaminated soil and discovered several
thousand small (less than 1 gallon) containers of
unidentified wastes. In October 1991, the drums
were removed of and disposed of offsite.
Between 1980 and 1990, sampling of residential
wells indicated the presence of organic
contaminants and PCBs. As a result, the
township extended municipal water service to
the affected area. This ROD provides an interim
remedy to restrict the offsite migration of highly
contaminated ground water. Subsequent actions
will address ground water contamination at a
depth of greater than 130 feet, offsite ground
water contamination, as well as air and soil
contamination. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, toluene, and xylenes; other
organics including pesticides and phenols; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes installing a ground water
collection trench, which will extend from the
surface of the site down'to approximately 10 to
15 feet below the surface; installing three ground
water extraction wells to a depth of 130 feet;
constructing an onsite treatment plant and
treating contaminated ground water using air
stripping, biological filtration, and activated
carbon adsorption; treating and disposing sludge
generated by the treatment processes offsite;
discharging the treated ground water onsite via
an above-ground pipe to the stream flowing
along the eastern property boundary; and
conducting ground and surface water monitoring
to measure the potential migration of hazardous
substances from the site. The estimated present
worth cost for this remedial action is $7,700,000,
which includes an annual O&M cost of $915,000
for 5 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on the more stringent of State or
Federal standards and include arsenic 0.50 ug/1
(State), benzene 1 ug/1 (State), chromium 50 ug/1

CIRCUITRON, NY
March 29,1991
SITE HISTORY/DESCRIPTION:
The one-acre Circuitron site is a former electronic
circuit board manufacturing facility in East
Farmingdale, Suffolk County, New York.
Surrounding land use is industrial. A
23,500-square-foot building and a paved parking
area account for 95 percent of the site, and the
remaining portion is a small unpaved area
behind the building. From 1961 to 1986, circuit
board manufacturing operations including metal
plating were conducted onsite. Several onsite
areas were used for discharge of
process-generated wastes including one
authorized and two unauthorized leaching pools
located beneath the parking area, two cesspools,
and storm drains. At least two unauthorized
leaching pools are located beneath the floor of
the plating room. In 1984 and 1985, Circuitron
agreed to remediate all leaching pools and storm
drains, remove all hazardous materials from the
site, and conduct ground water monitoring.
However, before abandoning the premises in
1986, Circuitron remediated only one
unauthorized leaching pool under the building
and installed monitoring wells. In 1989, EPA
removed 20 waste drums and contaminated
debris from inside the building and three
above-ground tanks from the rear of the
building, and emptied two underground storage
tanks. Further EPA site investigations from 1988
to 1990 have characterized contaminants and
contaminated media. This ROD addresses
contaminated onsite soil and sediment. Ground
water remediation will be addressed in a
subsequent ROD. The primary contaminants of
concern affecting the soil, sediment, and debris
are VOCs including benzene, PCE, TCE, toluene,
and xylenes; other organics including PAHs,
PCBs, pesticides, and phenols; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating highly VOC-contaminated soil in the
southwest corner of the site using in-situ vapor
extraction; treating emissions using carbon
adsorption and disposing of any spent carbon
residuals offsite; excavating contaminated soil,
sediment, and debris from the leaching pools,
cesspools, and storm drains inside and outside of
the building; incinerating these materials offsite,
with offsite disposal of any residuals;
decontaminating the building by vacuuming,
incinerating, and disposing of 53 cubic yards of
sediment, accumulated dust, and debris offsite;
replacing the concrete floor overlying the
excavated leaching pits under the building; and
repaving the parking area. The estimated
present worth cost for this remedial action is
$685,675, which includes an annual O&M cost of
$3,850 for 4 years.
PERFORMANCE STANDARDS OR GOALS:
Performance standards for in-situ soil vapor
extraction are based on leachability modeling,
and include 1,1,1-TCA 1 mg/kg and TCE
1.5 mg/kg.

COLESVILLE MUNICIPAL LANDFILL, NY
March 29, 1991
SITE HISTORY/DESCRIPTION:
The 35-acre Colesville Municipal Landfill site is
a former municipal and industrial landfill in
Colesville, Broome County, New York. Land use
in the area is rural, and wetlands and woodlands
are present in the vicinity of the site. Many of
the 1,921 residents living within 3 miles of the
site use ground water from shallow and deep
aquifers and springs as their drinking water.
From 1969 until its closure in 1984, the landfill
accepted primarily municipal solid waste,
although some drummed industrial wastes were
accepted from 1973 to 1975. The majority of the
468,000 cubic yards of waste was disposed
within three trenches at the site, and the drums
were either buried intact, punctured, or crushed.
In 1983 and 1984, private investigations
identified that upper portions of the ground
water beneath the site and in the vicinity of the
site were being contaminated by the landfill.
The county provided temporary water supplies
and carbon filters to affected residences, and
conducted well monitoring. This ROD provides
a final remedy for the landfill waste and soil,
leachate seeps, associated contaminated
sediment, and ground water. The primary
contaminants of concern affecting the soil,
sediment, debris, and ground water are VOCs
including benzene, PCE, TCA, TCE; and metals
including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
cutting and regrading the sides and surface of
the landfill; constructing lined leachate collection
trenches; installing a multi-media cap over the
existing landfill; installing a gravel gas venting
layer in the landfill, with a filter fabric layer
placed over the gravel; seeding and mulching
the top soil layer of the landfill; pumping and
treatment of the contaminated ground water
beneath and downgradient of the landfill using
air stripping and metals treatment, and
discharging the treated water onsite to surface
water after disinfection by an ultra-violet
disinfection, if required; constructing a water
supply system for present and future affected
residences, and providing temporary water
supplies and carbon filtration units to affected
residences until construction is completed;
conducting long-term ground water monitoring;
and implementing institutional controls
including deed restrictions, and site access
restrictions such as fencing, as necessary. The
estimated present worth cost for this remedial
action is $5,135,000, which includes an annual
O&M cost of $250,000 for 4 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water cleanup goals
are based on the more stringent of State or
Federal MCLs including benzene 5 ug/1 (State),
PCE 5 ug/1 (State), TCE 5 ug/1 (State), toluene
5 ug/1 (State), and xylenes 5 ug/1 (State).
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented, if
necessary, to prevent the installation of drinking
water wells at the site and restrict activities
which could affect the integrity of the cap.

CONKLIN DUMPS, NY
March 29,1991
SITE HISTORY/DESCRIPTION:
The 8.5-acre Conklin Dumps site is an inactive
municipal landfill in Conklin, New York. Land
use in the area is rural. The site consists of two
municipal landfills referred to as the upper and
the lower landfills. The lower landfill is adjacent
to the 100-year floodplain of the Susquehanna
River, and is bordered by wetlands. Portions of
the landfill were operational between 1964 and
1975, and approximately 80,000 cubic meters of
waste material were disposed of onsite during
this time. In 1985, private investigations
identified the presence of leachate seeps from the
site and low levels of contaminants in ground
water. This first ROD addresses containment of
landfill leachate, and remediation of
contaminated ground water as a final remedy.
The primary contaminant of concern affecting
the leachate and ground water is chloroethane, a
VOC
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
cutting and regrading the landfill; installing a
gravel gas venting layer and multi-media cap
over the landfill material; installing a leachate
collection system and leachate collection
trenches or toe drains at the upper landfill, and
discharging leachate discharged offsite to a
POTW with or without pretreatment; allowing
natural degradation to reduce the contamination
in ground water; monitoring ground water; and
implementing institutional controls including
deed, land, and ground water use restrictions,
and site access restrictions such as fencing. If
the POTW is not available, the leachate will be
treated onsite using air stripping, followed by
discharging the treated effluent onsite to surface
water. The estimated present worth cost for this
remedial action is $4,352,078, which includes an
annual O&M cost of $86,669 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Natural degradation is expected to reduce the
concentration of chloroethane to below the State
level of 5 ug/1 within 7 to 9 years. Leachate
treatment levels were not specified, but will meet
NPDES requirements.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented as
necessary. These include measures to prevent
the installation of drinking water wells, and to
maintain the integrity of the cap.

CURCIO SCRAP METAL, NJ
June 28, 1991
SITE HISTORY/DESCRIPTION:
The 1-acre Curcio Scrap Metal site encompasses
two active scrap metal recycling businesses and
associated warehouses in Saddle Brook
Township, Bergen County, New Jersey. Land
use around the site is mixed industrial and
residential. Surface water drainage from the site
empties into Schroeder's Brook, located a few
hundred feet from the property, which drains
into a nearby lake. The site is situated above the
Brunswick Formation, which is a sole source
aquifer. This formation supplies potable water
to the public and private wells in the area. Since
1975, Curcio Scrap Metal, Inc. (CSMI) and Cirello
Iron and Steel Company (CISC) have recycled
scrap metals products onsite. In 1982, the State
identified cut electrical transformers stored
onsite, and pools of black oily fluid, which had
collected on the ground under and near the
transformers. Samples taken from this area and
from onsite soil in 1984 revealed contamination
by VOCs, organics, and metals. In 1985, the
State discovered an oil spill in a nearby pond,
approximately 200 feet from the Property. The
State determined that CISC was responsible for
the spill of approximately 200 gallons of
hydraulic fluid on the property and directed
CISC to remove contaminated soil. CISC
reportedly removed the bulk of the soil and
stored it in another onsite area. EPA issued an
Administrative Order on Consent to the PRPs on
May 27, 1988. Remedial Investigation activities
were initiated in 1989 by the PRPs under the
terms of this Order. In 1989, CISC caused a spill
of PCB-contaminated oil into onsite soil, and the
State required CISC to excavate and drum the
resulting contaminated soil. During the RI/FS,
PCBs and vinyl chloride, as well as other
contaminants were detected in the onsite ground
water. This ROD provides a final remedy for the
first operable unit (OU1), the approximately
1300 cubic yards of contaminated onsite soil.
Future RODs will address other
ground and surface water contamination. The
primary contaminants of concern affecting the
soil are PCBs and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, incinerating, and disposing of 1,800
cubic yards of PCB- and metal-contaminated soil
above action levels at an offsite RCRA/TSCA
incineration facility, along with any resulting
ash. The estimated present worth cost for this
remedial action is $7,500,000. There are no O&M
costs associated with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
All soil contaminated in excess of soil action
levels for metals and greater than PCB 1 mg/kg
will be excavated and treated offsite.
Chemical-specific goals for soil are based on
State soil action levels, and include
lead 250 mg/kg to 1000 mg/kg.

ENDICOTT VILLAGE WELL FIELD, NY
March 29, 1991
SITE HISTORY/DESCRIPTION:
The Endicott Village Well Field site consists of a
municipal well, the Ranney Well, and its zone of
influence, and is located in Endicott, Broome
County, New York. Ground water pumped
from the well serves as the primary drinking
water source for the area. Land use in the area
of concern includes a golf course, a sewage
treatment plant, an airport, a few industrial
tracts, two inactive landfills, and the Endicott
Landfill. The Endicott Landfill accepted
municipal and industrial waste from the late
1950's until 1975, and has been used to compost
sludge from the onsite sewage treatment plant
since 1982. In 1981, EPA detected VOC
contamination in the Ranney Well, which was
confirmed by subsequent State and local
investigations from 1984 to 1987. Consequently
in 1983, local authorities installed a diffused
aeration air stripping unit on the Ranney Well,
and in 1984 a purge well was installed to
intercept VOCs before impacting the Ranney
Well. A 1987 ROD provided for installation of a
packed column air stripper to treat water from
the Ranney Well. In 1988, EPA identified the
landfilled materials in the Endicott Landfill as
the probable source of ground water
contamination, and determined that the purge
well did not adequately prevent the movement
of contaminated ground water to the Ranney
Well. This ROD addresses management of
migration of the contaminant plume as an
interim remedy. Final restoration of the aquifer
and remediation of source material will be
addressed in a subsequent ROD. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, and
TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
upgrading the existing purge well system by
installing an additional purge well between the
landfill and the Ranney Well; pumping ground
water from the purge well and discharging the
water onsite to the sewage treatment plant, or
treating the water prior to discharge, based on
the results of purge well testing; and monitoring
purge well water. The estimated present worth
cost for this remedial action, assuming that no
treatment will be required is $376,000, which
includes an estimated annual O&M cost of
$24,000 for 30 years.

FIBERS PUBLIC SUPPLY WELLS, PR
September 30,1991
SITE HISTORY/DESCRIPTION:
The 540-acre Fibers Public Supply Wells site is in
Guayama, Puerto Rico. The site includes an
active pharmaceutical plant (AWPI); two former
manufacturing facilities, one of which
encompasses two former settlement lagoons and
a soil disposal area; and five public supply wells.
Land use in the area is mixed agricultural and
light industrial. The site overlies a class II
aquifer. In addition, the Caribbean Sea is located
2 miles south of the site. From 1966 to 1976,
Fibers International Corporation (FIC)
manufactured nylon fibers onsite. From 1976 to
1980, Chevron Chemical Company (CCCPR)
expanded the operations of the FIC plant to
include the production of polypropylene fibers.
Both FIC and CCCPR operations used organic
solvents and degreasing solvents in their onsite
process. Wastewater containing these solvents
was directed to two settling lagoons, through the
process sewer system for preliminary treatment,
before being piped to an offsite biological
treatment system. FIC lined the lagoons in 1969
to reduce the seepage of treatment wastewater.
In 1978, CCCPR installed an onsite system for
treating process and sanitary wastewater, and
the treated effluent was directed to the settling
lagoons before offsite discharge to the sea.
CCCPR ceased onsite operations in 1980. State
and private site investigations in 1983 revealed
the presence of elevated levels of organics and
inorganics in soil and ground water. Between
1984 and 1985, AWPI remodeled the facilities,
and in 1985 began pharmaceutical manufacturing
operations. Also in 1985, AWPI excavated
portions of the settling lagoons and enlarged the
stormwater retention pond to encompass the
lagoon area. AWPI excavated 2,500 cubic yards
of the lagoon sludge and asbestos-contaminated
liner material, and deposited the material at an
onsite soil disposal area. This ROD addresses a
final remedy for source contamination in the soil
disposal area and ground water. The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including PCE and
TCE; other organics; metals including chromium
and lead; and other inorganics including
asbestos.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating 9,010 cubic yards of contaminated
material from the soil disposal area and
transporting the soil offsite to a landfill
authorized to accept asbestos; conducting soil
sampling; controlling dust during remediation to
prevent exposure and to protect workers and the
local community during the transportation of
asbestos-containing material (ACM); restoring
and covering the excavated area with 6 inches of
fill and 6 inches of top soil, followed by
revegetating the area; onsite pumping and
treatment of the 200-acre contaminated ground
water plume from five recovery wells using
filtration and air stripping, and discharging the
treated water onsite to a nearby irrigation canal
to recharge the aquifer; and installing monitoring
wells near the coastline to monitor potential salt
water encroachment. The estimated present
worth cost for this remedial action is $6,686,591,
which includes an annual O&M cost of $270,868
for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Soil goals for asbestos are based on NESHAPs
under the CAA, which consider that materials
containing asbestos in concentrations exceeding
1 percent be regarded as ACM. Ground water
clean-up goals are based on State and Federal
MCLs. Goals for soil include asbestos 1 percent
by volume. Chemical-specific ground water
goals include PCE 0.005 mg/1 (MCL) and TCE
0.005 mg/1 (MCL). EPA may invoke an ARAR
waiver for ground water if the remediation
program indicates that reaching MCLs in the
aquifer is technically impracticable.

located northwest of the landfill. From 1950
until its closure in 1984, the site was used and
operated by the Fort Dix Military Reservation to
dispose of various wastes including household
waste from the military base, paints, thinners,
demolition debris, ash, and solvents. From 1968
to 1984, McGuire Air Force Base also used the
landfill for waste disposal. Landfilling
operations consisted of excavating a series of
parallel trenches and filling with waste materials.
Waste disposal began at the northern portion of
the landfill in 1950 and proceeded in a southerly
direction to the southern boundary of the
landfill. In addition to the landfill, during 1982,
the Army used a pit in the southwestern area of
the site to dispose of mess hall grease and
degreasing agents. A 1982 State investigation
revealed ground water contamination beneath
the site that had resulted from landfill leachate.
This ROD addresses final source control at the
site; however, if additional investigations reveal
significant increases in unacceptable risk to
human health and the environment, then
additional remedial actions will be proposed.
The primary contaminants of concern affecting
the soil and debris are VOCs including benzene
and toluene; other organics including PAHs; and
metals including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the 50-acre southern portion of the
landfill with a clay or geomembrane cap;
developing a soil erosion and sediment control
plan; long-term ground water, surface water, and
air monitoring; and implementing institutional
controls including deed, land, and ground water
use restrictions, and site access restrictions such
as fencing. The estimated capital cost for this
remedial action is $12,600,000, with an annual
O&M cost of $218,900 for the first 2 years and
$199,900 for years 3-30.
PERFORMANCE STANDARDS OR GOALS:
Not applicable.
INSTITUTIONAL CONTROLS:
Institutional controls including land use, ground
water use, and deed restrictions will be
implemented at the site.

FRONTERA CREEK, PR
September 30,1991
SITE HISTORY/DESCRIPTION:
The Frontera Creek site is composed of 13
industrial facilities and 200 acres of associated
lagoons within the municipality of Humaco,
Puerto Rico. The site includes Frontera Creek,
the industrial properties adjacent to the creek,
the Frontera lagoons, and the Ciudad Cristiana
housing development located adjacent to the
creek. Land surrounding the site consists of
mixed residential and industrial areas, and a
wildlife refuge. From 1971 to 1981, several
industries within the site including Technicon
Electronics used mercury in manufacturing
processes and discharged wastewater directly
into Frontera Creek. The Commonwealth of
Puerto Rico Environmental Quality Board (EQB)
fined Technicon in 1978 for these processes,
resulting in the cessation of its mercury
discharges to the creek. During investigations in
1986, EPA identified mercury in surface soil and
sediment on Technicon property associated with
the storage, use, or discharge of mercury-
containing compounds. This ROD addresses
contaminated soil and sediment on the
Technicon property, and provides a final remedy
for the site. The primary contaminant of concern
affecting the soil and sediment is mercury.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating 180 cubic yards of soil and 370 cubic
yards of sediment contaminated with mercury;
dewatering and containing the excavated
material, followed by disposing of the material
offsite at a RCRA Subtitle D or C waste facility;
pretreating wastewater generated from
dewatering, followed by onsite discharge to
Technicon's wastewater treatment plant, or
offsite to a local POTW; performing confirmatory
soil sampling in the remediated areas to verify
that mercury concentrations in residual and
onsite materials do not exceed the clean-up
levels; and regrading and revegetating the
remediated areas. The estimated present worth
cost for this remedial action ranges from
$562,000 to $730,000, based on whether the waste
is disposed of as a solid or hazardous waste,
respectively. There are no O&M costs associated
with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
Clean-up levels for the soil and sediment onsite
were established based on a site-specific risk
assessment and an HI=1, and include mercury
35 mg/kg.

GARDEN STATE CLEANERS, NJ
September 26,1991
SITE HISTORY/DESCRIPTION:
The 3,000-square-foot Garden State Cleaners
(GSC) site is an active dry cleaning operation in
Minotola, Bueno Borough, Atlantic County, New
Jersey. Land use in the area is residential and
commercial, and local residents obtain drinking
water from the Borough municipal water supply
system. From 1966 to the present, dry cleaning
activities using PCE were conducted at the GSC
site, and until 1985, wastes were discharged
through pipes directly into the ground. An
adjacent Superfund site, the 1.2-acre South Jersey
Clothing Company (SJCC) facility, has
manufactured and dry cleaned military clothing
using PCE and TCE since 1940 and also
discharged wastewaters onsite. SJCC also stored
solvents and VOC-contaminated wastewaters
onsite in leaking drums and tanks. In 1981,
SJCC reportedly removed thirty-three 55-gallon
drums of contaminated soil from the facility. In
1984, State investigations showed elevated levels
of PCE in ground water adjacent to and
downgradient from the GSC and SJCC facilities,
and elevated levels of PCE and TCE in onsite
soil. SJCC installed a ground water pump and
treatment system under a State Order in 1985,
and in 1989, began installing a limited soil vapor
extraction system near a TCE storage tank that
ruptured in a 1979 fire. This project was
abandoned with the start of EPA's RI. Because
the GSC and SJCC sites are in proximity to one
another and have similar contamination, the sites
will be remediated concurrently. This ROD
addresses remediation of contaminated soil and
ground water at both the GSC and SJCC sites, as
a final remedy. The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene, PCE, TCE, and
toluene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating onsite approximately 1,600 cubic yards
of contaminated soil using in-situ vapor
extraction; treating the contaminated wastewater
from the vapor extraction processes onsite using
an air stripping column; treating air emissions
using carbon adsorption units; pumping and
onsite treatment of contaminated ground water
using air stripping and carbon adsorption;
reinjecting the treated ground water upgradient
from the site; regenerating spent activated carbon
from both treatment processes offsite; conducting
long-term ground water monitoring; and
implementing temporary institutional controls.
The estimated present worth cost for this
remedial action at the GSC site is $5,451,000,
which includes an estimated annual O&M cost of
$249,500 for 70 years. The estimated present
worth cost for the remedial action at the GSC
and SJCC sites is $11,169,000, which includes an
annual O&M cost of $542,000 for 70 years.
PERFORMANCE STANDARDS OR GOALS:
Federal and State agencies have agreed to jointly
establish Interim Soil Action Level (ISAL)
clean-up goals of 1,000 ug/kg for PCE and TCE,
given the predominance of the two compounds
at the site. Ground water remediation goals are
based on the more stringent of SDWA Federal
and State MCLs, and include PCE 1 ug/1 (State)
and TCE 1 ug/1 (State).
INSTITUTIONAL CONTROLS:
Temporary institutional controls will be
implemented onsite while the need for providing
home treatment units for individual residents is
evaluated.

GENERAL MOTORS/CENTRAL FOUNDRY DIVISION, NY
December 17,1990
SITE HISTORY/DESCRIPTION:
The 270-acre General Motors/Central Foundry
Division site is an active aluminum casting plant
in Massena, St. Lawrence County, New York.
The site is bordered by the St. Lawrence River to
the north, the St. Regis River Mohawk Indian
Reservation (which includes Turtle Creek) to the
east, the Raquette River to the south, and a
manufacturing facility to the west. Surrounding
land use is mixed residential and industrial. The
site overlies a surficial alluvial aquifer and is
adjacent to wetlands, both of which have been
contaminated. Additional onsite features of
concern include the unlined North and East
Disposal Areas and the Industrial Landfill, which
contain contaminated soil, debris, and sludge;
four unlined Industrial Lagoons, which contain
contaminated liquids, sludge, and soil; the rivers
and creek which contain contaminated sediment;
contaminated soil on the St. Regis Mohawk
Reservation and on General Motors property;
and contaminated associated wetlands. From
1959 to 1980, hydraulic fluids containing PCBs
were used in the onsite aluminum casting
operations. During the 1960's, PCB oil-laden
wastewater was routinely discharged to one of
the four industrial lagoons resulting in sludge
buildup. Wastewaters were discharged to the St.
Lawrence River. During the mid-1970's, the
migration of water and sludge through a
breached berm surrounding the East Disposal
Area resulted in PCB contamination on the St.
Regis Reservation and in Turtle Creek. Further
contamination stemmed from the placement of
PCB-contaminated soil on the bank of the
Raquette River, as well as from discharge of
surface water run-off from the site to the
Raquette River. In 1976, a wastewater treatment
system, that included a lagoon for solids settling
was installed, and this resulted in a buildup of
PCB-laden sludge in the onsite lagoon. This
PCB-laden sludge from the lagoon was
periodically removed to the East and North
Disposal Areas and the Industrial Landfill. Solid
industrial wastes were disposed of in the
Industrial Landfill as well. Investigations by
General Motors from 1985 to 1989 confirmed and
characterized onsite and offsite contamination in
soil, sediment, sludge, and ground water. As a
result, in 1988 an interim cap was placed over
the Industrial Landfill. This ROD provides a
final remedy for all site areas and media except
the East Disposal Area and the Industrial
Landfill, which will be addressed in a
subsequent ROD. The primary contaminants of
concern affecting the soil, sediment, sludge,
debris, ground water, and surface water are
PCBs, and to a much lesser degree, VOCs
including TCE; and other organics including
PAHs and phenols.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
dredging and excavating approximately 62,000
cubic yards of contaminated soil and sediment
from PCB "hot spots" in the St. Lawrence and
Raquette rivers, Turtle Creek, and associated
wetlands and riverbanks; excavating
approximately 142,000 cubic yards of sludge,
soil, and debris from the North Disposal Area
and the four Industrial Lagoons (two of the four
of the lagoons are inactive and will be
remediated currently, the two active lagoons will
be remediated after they are taken out of
service); excavating approximately 49,000 cubic
yards of soil from the Reservation and General
Motors property; dewatering and treating
dredged and excavated material using
bioremediation, another equivalent treatment, or
incineration based on treatability test results;
disposing of residuals and material with
low-level contamination onsite, placing a
vegetated cap over the residuals; pumping and
onsite treatment of contaminated ground water;
discharging the treated water onsite to surface
water; implementing interim surface runoff

$197,000 for years 9-10, $464,000 for years 11-13,
and $197,000 for years 14-30.
PERFORMANCE STANDARDS OR GOALS:
Excavation levels for PCB-contaminated
materials are based on TSCA requirements and
St. Regis Mohawk PCB clean-up requirements,
and include 1 mg/kg (TSCA) for sediment in the
St. Lawrence and Raquette Rivers, 1 mg/kg (St.
Regis) for soil on the St. Regis Reservation,
0.1 mg/kg (St. Regis) for sediment in Turtle
Creek, and 10 mg/kg (TSCA) for onsite soil and
sludge on the General Motors facility.
PCB-contaminated material will be treated to a
level of 10 mg/kg or less. Phenols in onsite
solids will be remediated to a level of 50 mg/kg.
Ground water clean-up standards are based on
State standards, and include TCE 5 ug/1,
PCBs 0.1 ug/1, and phenols 1 ug/1.

GENZALE PLATING, NY
March 29,1991
SITE HISTORY/DESCRIPTION:
The Genzale Plating site is an electroplating
facility, which occupies a 24,000-square-foot area
in Franklin Square, Nassau County, New York.
Land use in the area is predominantly
residential, with a wetlands area located
approximately 3 miles southeast of the site. The
site overlies a Gass II aquifer, which is tapped
by three water supply wells within 1.5 miles of
the site. Since 1915, the Genzale Plating
Company, Inc., operated an electroplating facility
onsite. Records indicate that copper, silver, zinc,
cadmium, nickel, and chromium compounds, as
well as acids and cleaners, were used during
plating processes. Wastewaters generated from
the electroplating operations were discharged to
four subsurface leaching pits. Following a 1981
county inspection, the owner was required to
discontinue onsite contaminant discharge to the
leaching pits. Testing of the wastewater samples
from the pits indicated heavy metal
concentrations in excess of State discharge
standards. In 1982, 36 cubic yards of
contaminated material were excavated; but the
entire excavation was never completed. In April
1983, a State investigation determined that onsite
contaminants presented a potential public health
threat because the site is in close proximity to
public water supply wells. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE and TCE;
other organics including PAHs; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes treating soil using in-situ vacuum
extraction and vapor phase carbon adsorption to
control emissions, followed by excavating 1,600
cubic yards of the treated soil and 480 cubic
yards of topsoil and material from the leaching
pits, followed by offsite treatment and disposal;
backfilling the excavated areas with clean soil;
pumping and treatment of ground water using
precipitation to remove metals, followed by air
stripping, with reinjection onsite and offsite
disposal of treatment residuals. The estimated
present worth cost for this remedial action is
$6358,700, which includes an annual O&M cost
of $223,800.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals include
TCE 1 mg/kg. Ground water treatment will be
designed to reduce the metals concentrations in
the treated ground water below the Federal and
State ground water standards.

GLOBAL LANDFILL, NJ
September 11,1991
SITE HISTORY/DESCRIPTION:
The 57.5-acre Global Landfill is an inactive solid
waste disposal facility in Old Bridge Township,
Middlesex County, New Jersey. The facility is
bordered by wetlands to the northeast, southeast,
and southwest, and a former sand borrow pit
and wooded area to the northwest. Land use in
the area is primarily residential. Onsite features
include a 51-acre landfill, a 6.5-acre northwest
landfill extension, and an inactive 1.7-acre
leachate collection pond. Municipal water
supply wells are located approximately 1 mile
north of the landfill. From 1968 until its closure
in 1984, the Global Landfill site was used for
non-hazardous solid waste disposal. As a result
of a slope failure in 1984, landfill wastes were
exposed, the dyke was breached, and the wastes
spilled into an adjacent wetlands area.
Subsequently, the State ordered all onsite
disposal operations to cease. From 1988 to 1991,
EPA and State site investigations identified 63
buried 55-gallon drums containing hazardous
wastes including VOCs, organics, and metals
within both the waste mound and northwest
extension. This ROD addresses Operable Unit 1
(OU1), the landfill wastes. A second ROD will
address possible offsite ground water and
surface water contamination, and wetland areas,
as OU2. The primary contaminants of concern
affecting the soil and sediment are VOCs
including benzene, PCE, TCE, toluene, and
xylenes; other organics; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the landfill with a synthetic and clay
cap; constructing a soil stabilization berm;
constructing and operating a gas management
system, and stormwater and leachate collection
systems; pumping leachate and condensate from
the gas collection system to a holding tank, and
subsequently transporting the waste offsite for
treatment and disposal (this constitutes an
interim remedy for the leachate); disposing of
sludge offsite at a RCRA facility; implementing
a monitoring program to ensure the effectiveness
of the remedy; mitigating any affected wetlands;
and implementing site access restrictions such as
fencing. Onsite leachate treatment that would
replace the offsite leachate treatment and
disposal provided for in this ROD, may be
initiated as part of the ground water remedy in
the next ROD, as part of the preferred leachate
management alternative. This may include
treatment using powdered activated carbon,
nitrification and denitrification, and UV
disinfection, followed by discharging the treated
effluent onsite to the Cheesequake Creek. The
estimated present worth cost of this remedial
action is $30,353,200, which includes an annual
O&M cost of $865,100 based on onsite treatment
of leachate.
PERFORMANCE STANDARDS OR GOALS;
A waiver of the New Jersey Hazardous Waste
Landfill Closure Regulations will be required on
the basis of technical impracticality due to the
large volume of waste to be removed. The
remedy will meet the appropriate Federal and
State guidelines and requirements for subsurface
gas and leachate management systems and
surface water systems. No chemical-specific
standards were provided.

HERTEL LANDFILL, NY
September 27,1991
SITE HISTORY/DESCRIPTION:
The 80-acre Hertel Landfill site consists of a
13-acre former municipal landfill and adjacent
land in Plattekill, Ulster County, New York.
Land use in the area is predominantly
residential, with wetland areas adjacent to the
site. The site overlies two natural aquifers.
From 1963 to 1975, Hertel Enterprises used the
site for the disposal of municipal solid waste. In
1975, the landfill was purchased by Dutchess
Sanitation Services, which had been hauling and
disposing of refuse from Dutchess County in the
Hertel Landfill since 1970. It is estimated that
240,000 cubic yards of waste were disposed
onsite during landfill operations. In 1976, the
site was shut down for a variety of violations,
including illegal dumping of industrial wastes
and violating a town ordinance prohibiting the
disposal of non-local waste. As a result of these
improper disposal practices, a number of State
investigations were conducted, which identified
contamination by various organic compounds
and metals in the onsite soil and ground water.
This ROD addresses soil contaminated by
landfill wastes, and ground water contaminated
by landfill leachate. The primary contaminants
of concern affecting the soil, sediment, debris,
and ground water are VOCs including benzene,
toluene, and xylenes; other organics including
phenols; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
regrading and compacting the landfill mound to
provide a stable foundation for cap placement;
constructing a 13-acre multi-layer cap over the
landfill with an associated gas venting system;
sampling soil along the western portion of the
disposal area to determine the need to extend
the cap or to consolidate the soil beneath the cap;
monitoring air to ensure that air emissions
resulting from the cap construction meet ARARs;
ground water pumping and treatment using an
innovative treatment system consisting of
precipitation and membrane microfiltration to
remove metals and solids, and an ultraviolet
light and hydrogen peroxide oxidation system to
remove organics; performing a treatability study
to demonstrate the effectiveness of the
innovative technology; implementing a
contingency remedy consisting of precipitation,
clarification, and filtration to remove metals and
suspended solids, and carbon absorption to
remove organic compounds, if the treatability
study indicates that the selected innovative
ground water treatment technology is not
effective; discharging the treated water onsite,
and disposing of treatment residuals in
accordance with RCRA Land Disposal
Restrictions; evaluating and mitigating affected
wetlands; conducting ground water monitoring
to observe flow patterns above and below the
landfill; and implementing institutional controls
including deed restrictions, and site access
restrictions such as fencing. The estimated
present worth cost for this remedial action is
$8,207,000, which includes an annual O&M cost
of $267,000 for years 0-12, $162,800 for years
13-17, and $31,000 for years 18-30. The present
worth cost for the contingency remedy is
$8,774,000, with the same O&M costs.
PERFORMANCE STANDARDS OR GOALS:
Capping will prevent direct contact exposure to
contaminated soil, and will result in risks that
are less than EPA's target levels of 10"6 for
carcinogenic risks and an HI=1. Ground water
clean-up goals are based on Federal and State
standards, and include total xylenes 5 ug/1

JUNCOS LANDFILL, PR
September 24,1991
SITE HISTORY/DESCRIPTION:
The approximately 20-acre Juncos Landfill site is
an inactive municipal waste landfill in the City
of Juncos, Puerto Rico, Land use in the area is
predominantly residential, with a housing
development located along the northern border
of the site. Two unnamed tributaries are located
outside the eastern and western borders of the
site and flow to the Rio Gurabo. Municipal
wastes including broken and/or intact mercury
thermometers, were disposed of at the site from
1957 to 1977, and in 1981, the site was closed.
Several EPA investigations revealed the presence
of mercury and VOCs in the soil, offsite leachate,
and air. In 1984, under an Administrative Order,
EPA required the PRP to place a soil cover over
some portions of the landfill where wastes were
exposed, and to assess risks posed by potential
mercury contamination. This ROD is the first of
two operable units (OUs) and addresses
contaminated soil and soil/leachate. A future
ROD will provide for remediation of potential
ground water contamination as a result of
migrating leachate, as OU2. The primary
contaminants of concern affecting the soil and
debris are VOCs; other organics including
phenol; and metals including arsenic, chromium,
lead, and mercury.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing a single barrier cap over the landfill
to reduce surface infiltration, prevent direct
contact, limit gas emissions, and control erosion;
installing a passive landfill gas venting system,
which could be converted to an active system if
monitoring shows this is needed; clearing and
grubbing existing vegetation on the landfill area,
and regrading the landfill; installing, if
necessary, a leachate control system composed of
a leachate storage system prior to offsite
treatment of leachate; providing for erosion
control appurtenances including drainage
channels, and stilling and sediment basins;
conducting long-term monitoring of air,
sediment, surface water, and leachate; relocating
families living in homes located along the
immediate north face of the landfill during the
construction phase; and implementing
institutional controls including deed restrictions,
and site access restrictions including fencing.
The estimated present worth cost for this
remedial action is $4,420,000, which includes an
annual O&M cost of $176,100.

LOVE CANAL (93rd STREET) (AMENDMENT), NY
May 15,1991
SITE HISTORY/DESCRIPTION;
The Love Canal site is an inactive hazardous
waste site located in Niagara Falls, New York.
The 19-acre 93rd Street School site, one of several
operable units for the Love Canal Superfund site,
is the focus of this ROD. This subsite is located
less than one mile northwest of the Love Canal
disposal area and is within the Love Canal
Emergency Declaration Area. Onsite features
include the 93rd Street School building and
adjacent vacant land. The site is bordered by
Bergholtz Creek to the north and residential
properties to the east, west, and south. From
1942 to 1953, Hooker Chemicals and Plastics
Corporation (now Occidental Chemical
Corporation) disposed of over 21,000 tons of
various chemicals including dioxin-tainted
trichlorophenols at the Love Canal site. In 1950,
after the site was deeded to the City of Niagara
Falls Board of Education, the 93rd Street School
was built. In 1954, a second school, the 99th
Street School, was built adjacent to the
mid-portion of the Canal. Before construction of
the 93rd Street School, a drainage swale had
crossed the site. In 1954, the site was graded to
its present contours with approximately 3,000
cubic yards of fill materials including fill from
the 99th Street School. The fill material is
reported to contain fly ash and BHC (a pesticide)
waste. During the mid-1970's, contaminated
leachate migrated to the surface of the Canal, to
some residential basements adjacent to the Canal,
and through sewers to area creeks. Those homes
have been demolished, and the sewers and
creeks in the Love Canal Emergency Declaration
Area have been remediated. In 1980, the 93rd
Street School was closed because of public health
concerns related to the potentially contaminated
fill material. Investigations conducted in 1988
revealed the presence of VOCs, other organics,
and metals in the soil. During previous
investigations, it was determined that low level
contamination present in the ground water
compared to the ground water quality in the
area and did not pose an exposure threat to the
concerned population. A 1988 ROD addressed
source control through excavating and
solidifying/stabilizing the excavated material,
placing the material into the same unit, and
capping with a low permeability soil cover. The
remedial action was not implemented and has
now been reevaluated in light of the Niagara
Falls Board of Education's 1989 plan to restore
the 93rd Street School as an educational facility
and to address objections to reopening the school
if contaminated soil remains onsite. This ROD
amends the 1988 ROD, and addresses final
remediation of onsite contaminated soil through
excavation and offsite disposal. The primary
contaminants of concern affecting the soil are
VOCs including toluene and xylenes; other
organics including PAHs and pesticides; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION;
The amended remedial action for this site
includes excavating and disposing of offsite 7,000
cubic yards of contaminated soil from hot spot
areas; backfilling excavated areas with site soil of
lower contamination; and capping and regrading
the area with fill material. The estimated present
worth cost for this amended remedial action is
$2,250,000, which does not include O&M costs.
PERFORMANCE STANDARDS OR GOALS:
Soil action levels were not provided. Ground
water clean-up goals were waived due to
technical impracticability.

MATTIACE PETROCHEMICALS, NY
June 27,1991
SITE HISTORY/DESCRIPTION:
The 2-acre Mattiace Petrochemicals site is an
inactive liquid storage and redistribution facility
in Glen Cove, Nassau County, New York.
Surrounding land use is primarily industrial.
Glen Cove Creek, a potential wetland area, is
located south of the site. The site overlies a
system of three unconsolidated sedimentary
aquifers, of which the surficial Upper Glacial
Aquifer has been affected by onsite
contamination. From the mid-1960's to 1986,
organic solvents were stored, blended, and
repackaged onsite. Onsite features involved
with the operation included a metal Quonset
hut, a concrete fire shed, a leaching pond, a
partially covered concrete loading dock, and
32 underground and 24 above-ground storage
tanks. Drums were reconditioned onsite, and the
resulting water/sol vent mixtures were
discharged to above-ground tanks or to an onsite
leaching pond. A solvent water separator was
used to collect overflow from the above-ground
tanks for discharge to the leaching pond. There
is evidence, however, that overflow from these
tanks may have been discharged directly into the
soil. In 1988, EPA characterized and disposed of
100,000 gallons of hazardous liquids offsite from
approximately 24 above- and 32 underground
storage tanks. In 1989, a second EPA
investigation identified approximately 25 buried
drums and numerous other containers that were
leaking contaminated material into the
surrounding soil and ground water. A 1990
ROD provided for removal of onsite buried
drums containing sludge, as well as the
associated highly contaminated soil as Operable
Unit 2 (OU2). In 1989, EPA characterized onsite
contamination, and discovered a layer of "free
product" floating on top of contaminated ground
water and contaminated sediment in Glen Cove
Creek. This ROD addresses remediation of
onsite source materials, as well as management
of migration of contaminated shallow ground
water. The primary contaminants of concern
affecting the soil, debris, and ground water are
VOCs including PCE, TCE, toluene, and xylenes;
other organics including PAHs, pesticides, and
phenols; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and treating offsite 208 cubic yards of
pesticide-contaminated "hot spot" soil, possibly
by incineration, followed by offsite disposal of
residuals; backfilling excavated areas with clean
soil; treating 17,141 cubic yards of contaminated
soil using in-situ vacuum extraction, followed by
activated carbon to control off-gases, as needed;
decontaminating and demolishing the Quonset
hut, 24 above-ground tanks, 32 underground
tanks, and 1,360 cubic yards of concrete and
asphalt, followed by offsite disposal; removing
15,000 gallons of "free product" using ground
water extraction wells and a skimmer pump,
followed by offsite treatment and disposal;
pumping and treatment of ground water using
precipitation and clarification as pretreatment to
remove metals, and air stripping to remove
organics, and reinjecting the treated water onsite;
treating air effluent from the air stripper using
thermal treatment; treating water effluent from
the air stripper using carbon adsorption, and
regenerating spent carbon offsite; performing
treatability studies; conducting a soil gas survey
to monitor off-gas migration; and monitoring
ground water, Glen Cove Creek sediment, and
surface water. The estimated present worth cost
for this remedial action is $15,930,592, which
includes an annual O&M cost of $692,997 for 30
years.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up goals are based on achieving an

NL INDUSTRIES, NJ
September 27,1991
SITE HISTORY/DESCRIPTION:
The 44-acre NL Industries site is an inactive,
secondary lead smelting facility in Pedricktown,
Salem County, New Jersey. Land use in the area
is predominantly residential and industrial. The
site is bordered by two tributaries to the
Delaware River, which receive surface discharges
from the site. The site overlies the Cape May
aquifer, a potential source of drinking water for
local residents. From 1972 to 1984, the site was
used to recycle lead from spent automotive
batteries, and the unused portions of the
batteries were buried in an onsite landfill.
During operations, batteries and other materials
containing lead were stored on paved and
non-paved areas onsite; and drums and debris
were scattered throughout the site, within and
outside of buildings, and on the paved areas.
There also are approximately 1,000,000 gallons of
contaminated standing water and 200 cubic
yards of associated sediment at the site.
Between 1973 and 1980, the State cited the PRP
for multiple violations of State air and water
regulations. In 1989, EPA began a multi-phased
removal action, which included consolidating
and encapsulating debris and lead-bearing
materials into separate piles totaling 9,800 cubic
yards of kiln slag and 200 cubic yards of lead
oxide; removing over 40,000 pounds of toxic and
reactive materials; incinerating 2,200 empty
drums offsite; and constructing a chain-link fence
to enclose the site. In addition, EPA conducted
a Focused Feasibility Study (FFS) to address the
remediation of slag and lead oxide piles, debris
and contaminated building surfaces, standing
water, and sediment. The FFS resulted in the
issuance of this Early Remedial Action ROD,
designated as Operable Unit (OU2). The nature
and extent of remaining contamination on the
site and areas adjacent to the site in various
environmental media, such as soil, sediment,
ground water, surface water, and air, are
currently being evaluated and will be addressed
as OU1 in a subsequent ROD. The primary
contaminants of concern affecting the slag and
lead oxide piles, sediment, debris, and standing
surface water are metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating onsite the slag and lead oxide piles
using solidification/stabilization and placing the
residual material onsite; decontaminating debris
and contaminated building surfaces, with offsite
treatment and disposal of debris that cannot be
decontaminated; treating and disposing of
standing water, wash water from the
decontamination process, and sediment offsite;
conducting environmental monitoring; and
implementing institutional controls including
land use restrictions. The estimated present
worth cost for this remedial action is $4,987,000,
which includes an annual O&M cost of $17,000.
PERFORMANCE STANDARDS OR GOALS:
The selected remedy will attain all Federal and
State ARARs. Chemical-specific clean-up goals
were not provided.
INSTITUTIONAL CONTROLS:
Institutional controls including land use
restrictions will be implemented at the site.

NASCOLITE, NJ
June 28,1991
SITE HISTORY/DESCRIPTION:
The 17.5-acre Nascolite site is an inactive acrylic
and plexiglass sheet manufacturing plant in
Millville, Cumberland County, New Jersey. The
site lies within the New Jersey coastal plain and
overlies clay, silt, sand, and gravel layers. The
majority of the site is wooded, with a wetland
located in the southwestern portion. Land use is
both industrial and residential, with homes
located 1,500 feet to the east and southeast of the
site. Site features include six buildings, which
served as the production facility, laboratory, and
company offices; and a drainage ditch. From
1953 to 1980, site operations included reclaiming
scrap material through depolymerization and
distillation processes. Residues from these
operations were discharged to the buried onsite
tanks, and wastewater was discharged to the
onsite drainage ditch. Decay of the structures
and asbestos fibers within the buildings pose a
threat to site workers. In 1980, although the
State ordered the plant to stop discharging
wastewaters into the onsite drainage ditch, well
water monitoring conducted during 1981
identified VOC-contamination in these wells. In
1984, the State identified over one hundred
55-gallon drums and several underground
storage tanks buried onsite. In 1987, the State
ordered Nascolite to remove some of the drums,
and later during 1987 and 1988, EPA removed
the remaining drums offsite. Perforations found
in one of the excavated tanks indicated the
likelihood that VOCs and lead had leaked into
and contaminated onsite soil, which was
confirmed by subsequent sampling. Also in
1987, EPA assumed the lead for the site, cleaned
and cut the waste material storage tanks into
scrap metal, and removed 20 cubic yards of soil
and 30 cubic yards of asbestos insulation. In
addition, the wastes in tanks and drums were
sampled, bulked into 1,825 gallons of
corrosive/ignitable liquid and 134 cubic yards of
solidified solvent sludge, and removed offsite.
A 1988 ROD addressed onsite ground water
contamination and provided for pumping and
treatment of ground water, provision of an
alternate water supply to affected residences,
and additional site studies. This ROD addresses
contaminated onsite soil, sediment, and
buildings. The primary contaminants of concern
affecting the soil, sediment, and debris are VOCs
including benzene, PCE, TCE, toluene, and
xylenes; and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, treating, and stabilizing 8,000 cubic
yards of unsaturated and wetlands soil
containing lead above 500 ug/kg; backfilling
excavation pits using the treated soil;
transporting wetland sediment not amenable to
stabilization offsite; restoring any affected
wetlands; conducting asbestos abatement,
followed by offsite disposal; demolishing site
structures in accordance with asbestos
regulations, followed by decontamination, onsite
treatment, recycling, or offsite disposal of
associated debris; and implementing institutional
controls. The estimated present worth cost for
this remedial action is $4,165,000, which includes
an annual O&M cost of $31,000.
PERFORMANCE STANDARDS OR GOALS:
All unsaturated soil contaminated with lead
above the action level of 500 ug/kg will be
excavated and stabilized onsite.
INSTITUTIONAL CONTROLS:
Institutional controls will be implemented to
ensure that the solidified mass is not disturbed.

The 7,400-acre Naval Air Engineering Center
(NAEC) site is an active air base in Jackson and
Manchester Townships, Ocean County, New
Jersey. Activities conducted onsite include
program research, engineering, development
testing and evaluation, and various warfare
support services. Land use in the area includes
residential, woodland, vast wetlands, and
associated floodplain areas. Approximately
65,400 residents of the townships are serviced by
several municipal supply wells located within
one mile of the site to the southeast and north.
From 1916 to 1919, the Eddystone Chemical
Company conducted chemical artillery testing
onsite. In 1921, the U.S. Navy took control of
the site and conducted operations involving the
use, handling, storage, and onsite disposal of
hazardous substances in various onsite buildings.
Site features within Area C include a barrel
storage area and fuel station (site 10), a fire
training area with unlined lagoons and an
oil/water separator (site 16), and an onsite fuel
farm with inactive dry wells that were removed
in 1982 (site 17). Preliminary investigations in
1983 by the U.S. Navy identified 44 onsite areas
of possible soil and ground water contamination,
and determined that the primary sources of soil
and ground water contamination in Area C
(comprised of sites 10, 16, and 17) were leaky
valves and pipes, dispensing pumps, the
underground fuel oil tanks, overflowing dry
wells, and other accidental onsite chemical spills
and releases. In 1988, NAEC removed and
replaced the onsite tanks. This ROD provides an
interim remedy for contaminated soil and
ground water in Area C Sites 10, 16, 17, as
operable unit 1. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, TCE, and xylenes; other
organics including PAHs; and metals including
arsenic and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and pretreating ground water to
remove metals, residual amounts of free product,
and solids, followed by offsite disposal of solids
and free product; onsite treatment using air
stripping and vapor phase carbon adsorption to
remove VOCs, and polishing the effluent using
granular activated carbon; spray irrigating or
infiltrating the treated ground water over the
onsite soil; regenerating the spent carbon offsite;
and disposing of all solids, residual sludge, and
free product offsite. The estimated capital cost
for this remedial action is $700,000, with an
annual O&M cost of $100,000 for 3 years.

From 1916 to 1919, the Eddystone Chemical
Company conducted chemical artillery testing
onsite. In 1921, the U.S. Navy took control of
the site and conducted operations involving the
use, handling, storage, and onsite disposal of
hazardous substances in various buildings.
Preliminary investigations by the Navy from
1983 to 1986 identified potential onsite soil and
ground water contamination in 44 site areas,
including Area H, site 32, which has been
designated as operable unit 2 for remediation.
Site 32 consists of the launching end of five test
tracks and ancillary facilities including a
drainage system designed to receive oil and fuel
runoff from each track, a series of dry wells, and
several underground storage tanks.
Contamination in this area was thought to have
been the result of improper disposal of wastes in
five dry wells, various spills, leaking valves, and
other poor housekeeping practices. In 1988, the
Navy excavated and removed offsite the five dry
wells, contaminated soil, and underground
storage tanks to prevent potential discharges to
ground water. This ROD provides an interim
remedy for the second operable unit (OU2), the
ground water contamination in Area H, site 32.
The focus of this OU is ground water, although
some treatment of soil may occur. The primary
contaminants of concern affecting the ground
water are VOCs including PCE; other organics;
and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and pretreating ground water to
remove metals, soil, and residual amounts of free
product, followed by offsite disposal of solids
and free product; and onsite treatment using air
stripping and vapor phase carbon adsorption to
remove VOCs and polishing the effluent using
granular activated carbon; spray irrigating or
infiltrating the treated ground water over the
onsite soil to promote biodegradation;
regenerating the spent carbon offsite; and
disposing of all solids, residual sludge, and free
product offsite. The estimated capital cost for
this interim remedial action is $550,000 (latest

The 7,400-acre Naval Air Engineering Center
(NAEC) site is an active air base in Jackson and
Manchester Townships, Ocean County, New
Jersey. Activities conducted onsite include
program research, engineering, development
testing and evaluation, and various warfare
support services. Land in the area includes
residential areas, woodlands, vast wetlands, and
associated floodplain areas. The site lies within
the Toms River Drainage Basin, and adjacent to

bogs that drain into and out of the southeast
section of the site. Approximately 65,400
residents of the townships are serviced by
several municipal supply wells located within
1 mile of the site to the southeast and north.
From 1916 to 1919, the Eddystone Chemical
Company conducted chemical artillery testing
onsite. In 1921, the U.S. Navy took control of
the site and conducted operations involving the
use, handling, storage, and onsite disposal of
hazardous substances in various onsite buildings.
This ROD addresses operable unit 3, which
includes eight separate sites and a region known
as Area L. The sites include a disposal area (site
15), a gas station (site 18), an inactive disposal
area (site 23), a contractor disposal area located
along a drainage swale (site 26), recovery
systems test sites (site 27), a recovery systems
track site (site 30), a parachute jump circle (site
34), and a soil stabilization field test site (site 40).
Area L is located in the northwestern corner of
the facility in the vicinity of a BOMARC missile
explosion area. The explosion resulted in the
limited spread of a radioacative material,
plutonium. The results of the RI show no
evidence of significant contamination at the eight
sites and Area L. At most sites, contaminants
were not detected. In instances where
contaminants were detected, the levels were
usually well below State and Federal action
levels. Furthermore, investigations conducted
from 1985 to 1990 in Area L also concluded that
no significant levels of radiological
contamination were present in ground water,
soil, or sediment in this area. Therefore, there
are no contaminants of concern affecting this
site.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
no further action because no significant levels of
contaminants exist at the eight sites and Area L.
No additional action is necessary to protect
human health or the environment. There are no
costs associated with this no action remedy.

SITE HISTORY/DESCRIPTION:
The 7,400-acre Naval Air Engineering Center
(NAEC) site, which contains many subsites, is a
naval research design and testing facility near
the Jackson and Manchester Townships, Ocean
County, New Jersey. The site lies within the
Toms River Drainage Basin and contains 1,300
acres of flood-prone areas. Land use in the area
is part residential and part undeveloped. The
estimated 65,400 people who reside within the
Jackson and Manchester Townships receive their
water from municipal wells. This ROD focuses
on remediation of Area E (Site 28) within the
NAEC site. Currently, Area E features include
a former oil storage shed, former paint locker,
and five fuel storage containers. From 1957 to
1980, unknown quantities of waste oil, hydraulic
fluids, and solvents were discharged in Area E.
In 1988, the RI identified elevated VOC levels
and floating product, most likely gasoline, in the
ground water. Subsequent investigations in 1990
discovered a gasoline leak in an underground
pipe, which apparently was the source of ground
water contamination. Onsite actions have
included repairing the leak and excavating and
disposing of 65 cubic yards of visually-
contaminated soil. This ROD provides an
interim remedy for ground water contamination.
Future RODs will address the remaining
contaminated media including a final decision
for ground water. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, toluene, and xylenes; and
other organics including PAHs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes onsite pumping and pretreating
ground water using precipitation and filtration to
remove metals, solids and residual amounts of
free product, and air stripping to remove VOCs;
filtering the effluent from the treatment process
water using a granular activated carbon
polishing filter, and discharging the treated
water onsite in a spray irrigation and infiltration
system depending on the season; treating air

ROCKAWAY BOROUGH WELLFIELD, NJ
September 30,1991
SITE HISTORY/DESCRIPTION:
The 2.1-square mile Rockaway Borough Wellfield
site is a municipal well field in Rockaway
Borough, Morris County, New Jersey. Land use
in the area is predominantly residential. The
estimated 10,000 people who reside in Rockaway
Borough use the underlying glacial aquifer as
their sole source of drinking water. Beginning in
1980, a number of State investigations revealed
VOC-contaminated soil, sediment, and ground
water, which had originated from several source
areas within the Borough. In 1981, the Borough
constructed a granular activated carbon
adsorption treatment system that treated
approximately 900,000 gallons per day of raw
water pumped from the well field. Overall, the
system has reduced VOC concentrations in the
municipal water supply to levels meeting State
and Federal drinking water standards. A 1986
ROD provided for the continued operation and
maintenance of the existing ground water
treatment system, for a continuation of the RI/FS
to positively identify additional contaminant
sources, and for further delineation of the full
extent of contamination. The 1986 ROD did not,
however, address ground water restoration.
Recently, EPA also has approved a State-initiated
modification to the current treatment system to
include the installation of an air stripper as the
first stage in the treatment process. This ROD
addresses final restoration of the contaminated
onsite ground water to drinking water standards.
A future ROD will address the need for
remediation of the contaminant sources. The
primary contaminants of concern affecting the
ground water are VOCs including PCE and TCE;
and metals including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
onsite pumping and treatment of ground water
from two of three plumes of concern using
chemical precipitation and air snipping, followed
by reinjecting the treated ground water onsite
into the glacial aquifer; and conducting
environmental monitoring. Under this remedial
action, a single treatment facility would be
necessary for the two treatment areas, and no
active remedial measures would be taken for the
third plume. The estimated present worth cost
for this remedial action is $17,818,000, which
includes an annual O&M cost of $1,502,000 for
27 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on the more stringent of Federal or
State MCLs, and include PCE 1 ug/1 (State MCL)
and TCE 1 ug/1 (State MCL).

ROEBLING STEEL, NJ
September 26,1991
SITE HISTORY/DESCRIPTION:
The 200-acre Roebling Steel site is an inactive
steel wire and cable manufacturing facility in
Florence Township, Burlington County, New
Jersey. Site features include a 34-acre slag
disposal area, and 55 buildings connected by a
series of paved and unpaved access roads. Two
portions of the slag area lie within the 100-year
floodplain of the Delaware River. A public
playground, known as the Southeast Park, is
adjacent to the southeastern portion of the site,
and land surrounding the site consists of
farmlands, wetlands, and forested and residential
areas. The Roebling Steel site produced steel
products between 1906 and 1982. In recent
years, parts of the site have been used as a
storage facility for vinyl products, a warehouse
facility, a polymer-reclamation facility, a facility
for repairing and refurbishing refrigerated
trailers and shipping containers, a storage facility
for insulation, and an equipment storage facility
for a construction company. Approximately
1,458,000 cubic yards of slag material from
steel-making processes were used to fill in a
large portion of the bordering Delaware River
shoreline. In addition to the slag material, other
potential sources of contamination onsite include:
process buildings containing chemical treatment
baths, tanks, pits and sumps; a wastewater
treatment plant; two sludge lagoons; friable
asbestos insulation inside buildings and falling
from pipes; 52 railroad cars containing fly-ash,
dry sludge, and debris; and a landfill containing
rubble and debris. Because the site lacked
properly operated environmental control
facilities, several regulatory agencies have issued
notices of noncompliances to site owners over
the last 25 years. Based on Federal
investigations conducted in 1983, three removal
actions were conducted. In 1985, the State
removed explosive materials. In 1987, EPA
removed lab pack containers, drums of corrosive
and toxic materials, acid tanks, and compressed
gas cylinders. In 1990, EPA removed fencing
around the slag area. A 1990 ROD addressed
the remaining drums, tanks, transformers,
contaminated soil, baghouse dust, and chemical
and tire piles. This ROD addresses soil and
debris contamination in the slag area and in the
Southeast Park as OU2. Future RODs will
address final remedies for soil, sediment, debris,
ground water, surface water, and air. The
primary contaminants of concern affecting the
soil and debris are VOCs including benzene,
PCE, TCE, toluene, and xylenes; other organics
including PAHs, PCBs, and pesticides; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and transporting approximately
160 cubic yards of contaminated soil from two
areas of the Southeast Park to an offsite
treatment and disposal facility; backfilling the
excavated area with clean soil and revegetating
the area; conducting additional surface and
subsurface sampling to confirm the extent of
contamination and to test for exceedances of
regulatory levels; excavating and treating slag
areas that are leaching contaminants using a
mobile treatment unit that stabilizes the slag
material; conducting a treatability test to
determine the specific stabilization process;
dewatering of any slag material found below the
water table during excavation; collecting,
treating, and disposing of extracted water;
returning treated slag to an area above the water
table; reprocessing or offsite disposal of any slag
material leaching contaminants above regulatory
levels; excavating and offsite disposal of
localized areas of slag determined to interfere
with or be unaffected by the solidification/
stabilization process; offsite treatment and
disposal of slag if the remedial design
determines that the volume of slag to be treated
is small compared to the current estimate of

30,000 cubic yards; grading and capping the
34-acre slag area using a soil cover; providing
riprap along the river shoreline to minimize
erosion; conducting long-term ground water
monitoring; and implementing institutional
controls. The estimated present worth cost of
this remedial action is $12,220,100, which
includes an annual O&M cost of $344,200.
PERFORMANCE STANDARDS OR GOALS:
No promulgated Federal or State requirements
for soil contamination exist. However, the
remedy will comply with State Interim Soil
Action Levels for carcinogenic PAHs and
inorganic compounds in the slag and soil. The
remedy also wiJl comply with EPA's
chemical-specific guidelines for lead in soil,
which ranges from 500-1,000 mg/kg.
INSTITUTIONAL CONTROLS:
Institutional controls will be implemented to
restrict future excavations through the soil cover.

SINCLAIR REFINERY, NY
September 30,1991
SITE HISTORY/DESCRIPTION:
The Sinclair Refinery site is a former refinery in
Wellsville, Allegany County, New York. The site
is composed of a 90-acre refinery area, 10-acre
landfill area, and 14-acre offsite tank farm.
Surrounding land use is primarily residential.
The site borders the Genesee River, which is
used as a local source of drinking water supplied
by the Village of Wellsville Municipal System.
The underlying ground water flow at the site is
generally to the north and east, discharging
directly into the Genesee River. From 1901 to
1958, the site was used to process Pennsylvania
grade crude oil until a fire in 1958 halted
operations. Currently, some private companies
and the State University of New York occupy the
site. A 1981 site inspection revealed that debris
from the eroding landfill area has washed into
and contaminated the Genesee River. A 1985
ROD addressed operable unit 1 (OU1) and
provided for: removal and disposal of drums;
excavation and consolidation of the south landfill
area and filling of the excavated area with clean
soil; partial channelization of the Genesee River
to protect the landfill from erosion and flooding;
capping of the consolidated landfill; construction
of a fence around the entire landfill site; and an
evaluation of the refinery portion of the site.
This ROD addresses OU2, remediation of the
remaining contaminated areas at the site located
within the 90-acre refinery area and the offsite
tank farm including the contaminated ground
water beneath the refinery. Data collected
during the OU2 RI have not shown contaminant
levels in landfill ground water to be in excess of
Federal and State standards; therefore, EPA has
chosen not to address landfill ground water
remediation under this OU2 ROD. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene and
xylenes, semi-volatile compounds including
naphthalene and nitrobenzene, and metals
including arsenic and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating soil contaminated in excess of arsenic
25 mg/1 and lead 1,000 mg/1 to a depth of 1
foot; treating excavated soil onsite prior to
consolidation in the landfill; capping the landfill,
and filling and revegetating excavated areas;
conducting long-term monitoring of biota,
surface water, ground water, and soil-gas to
track any potential contaminant migration from
the sub-surface soil; onsite pumping and
treatment of contaminated ground water,
followed by discharging the treated ground
water onsite to the Genesee River or offsite to
the POTW; and implementing institutional
controls in the form of local zoning ordinances.
This ROD also provides contingency measures
for ground water all or some of which may be
implemented based on the monitoring data
colleted. These measures include variations in
pumping rates, implementing engineering or
institutional controls, monitoring specified wells,
reevaluation of remedial technologies, and
invoking chemical-specific ARAR waivers. The
estimated present worth cost for this remedial
action is $15,549,700, which includes an annual
O&M cost of $750,183 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific goals for soil include arsenic
25 mg/1 and lead 1,000 mg/1. Ground water
will be treated to attain Federal MCLs or State
standards.
INSTITUTIONAL CONTROLS:
Institutional controls will be recommended
onsite in the form of local zoning ordinances.

SOUTH JERSEY CLOTHING, NJ
September 26,1991
SITE HISTORY/DESCRIPTION:
The 1.2-acre South Jersey Clothing Company
(SJCC) site is an active clothing manufacturing
facility located in Minolta, Buena Borough,
Atlantic County, New Jersey. Land use in the
area is residential and commercial, and local
residents obtain drinking water from the
Borough municipal water supply system, Onsite
features include two buildings used for
manufacturing operations, as well as the remains
of a building damaged in a 1979 fire. Another
Superfund site, the 3,000-square-foot Garden
State Cleaners (GSC) site, is located 500 feet
south of the South Jersey Clothing site. GSC site
features include a small building covering much
of the site. In 1940, SJCC began manufacturing
military clothing using VOCs including TCE, as
part of the dry cleaning process. Based on State
records, wastewater containing TCE from these
processes was routinely discharged directly onto
the facility grounds, and other process wastes
were stored onsite in leaking drums. In
addition, State records indicate that the 1979 fire
may have resulted in the release of an estimated
275 gallons of TCE from an onsite storage tank.
State investigations in 1981 identified elevated
TCE levels onsite. Later in 1981, SJCC identified
and removed thirty-three 55-gallon drums of
TCE-contaminated soil; installed additional
ground water monitoring wells from 1981 to
1984; and installed a ground water pump and
treatment system under a State Order in 1985.
In 1989, SJCC began installing a limited soil
vapor extraction system in the vicinity of the
TCE storage tank that reportedly ruptured in the
1979 fire, but this action was abandoned at the
start of the RL Because the SJCC and GSC sites
are in proximity to one another and have similar
contamination, both sites will be remediated
concurrently. This ROD addresses soil and
ground water contamination at both the SJCC
and GSC sites, as a final remedy. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
TCE, and toluene.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
treating approximately 1,600 cubic yards of
onsite contaminated soil using in-situ vapor
extraction; treating the contaminated wastewater
from the vapor extraction processes onsite using
an air stripping column; treating air emissions
using carbon adsorption units; pumping and
onsite treatment of contaminated ground water
using air stripping and carbon adsorption,
followed by reinjecting the treated water
upgradient from the site; regenerating spent
activated carbon from both treatment processes
offsite; conducting long-term ground water
monitoring; and implementing temporary
institutional controls. The estimated present
worth cost for this remedial action at the SJJC
site is $5,718,000, which includes an estimated
annual O&M cost of $293,100 for 70 years. The
estimated present worth cost for this remedial
action at both the GSC and SJCC sites is
$11,169,000, which includes an annual O&M cost
of $542,000.
PERFORMANCE STANDARDS OR GOALS:
Federal and State agencies have agreed to jointly
establish Interim Soil Action Level (ISAL)
clean-up goals of 1,000 ug/kg for PCE and TCE,
given the predominance of the two compounds
at the site. Ground water remediation goals are
based on the more stringent of SDWA Federal
and State MCLs, and include PCE 1 ug/1 (State)
and TCE 1 ug/1 (State).

SWOPE OIL & CHEMICAL, NJ
September 27,1991
SITE HISTORY/DESCRIPTION:
The 2-acre Swope Oil & Chemical site is a
former chemical reclamation facility in
Pennsauken, Camden County, New Jersey. Land
use in the area is predominantly commercial and
industrial, and Pennsauken Creek lies 0.8 miles
northeast of the site. The estimated 10,000
residents use ground water from a public supply
well screened in the lower underlying aquifer
near the site as their drinking water supply. At
the time site operations ceased, pertinent site
features included a main building, distilling
house, diked tank farm, open drum storage area,
and an unlined lagoon. From 1965 to 1979,
Swope Oil & Chemical used the site for the
reclamation of chemicals. Site operations
included buying, selling, manufacturing, and
processing oils, chemicals, and paints, and
discharging waste liquids and sludge to an
excavated, unlined lagoon. Contaminated
material also was contained within a diked tank
farm and an exposed drum storage area. In
1975, State investigations showed that discharge
of wastes to onsite drainage ditches had resulted
in probable migration of chemicals to
Pennsauken Creek via storm sewers. The
owners were cited for several disposal violations
in 1975, and again in 1979, when the site
operations ceased. Beginning in 1984, PRPs
removed drummed wastes and 3,000 tons of
lagoon sludge, and also fenced the perimeter of
the site. Later in 1984, air strippers were
installed on Municipal Well 1 by the water
commission to remove VOC contamination
detected in the aquifer. A 1985 ROD provided
for removal, offsite disposal, and treatment of
storage tanks and their contents; demolition of
onsite buildings; and excavation and offsite
disposal of PCB-contaminated soil and sludge
area material. This ROD addresses remediation
of subsurface soil, which continues to leach
contaminants into ground water, as operable
unit 2. Future actions will evaluate whether
further source control measures or ground water
actions are necessary. The primary contaminants
of concern affecting the soil are VOCs including
PCE and TCE, and other organics including
DEHP and naphthalene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating onsite approximately 153,000 cubic yards
of contaminated unsaturated soil using in-situ
vacuum extraction with potential enhancement
of biodegradation of soil contaminants, if the
results of the treatability study so warrant;
treating air emissions using carbon adsorption or
thermal destruction prior to discharge, if
necessary; and monitoring soil and ground
water. The estimated present worth cost for this
remedial action is $2,099,000, which includes
estimated O&M costs of $397,500 for year 1 of
the vapor extraction system and $234,200 a year
for 5 years of ground water monitoring.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based
on New Jersey Interim Soil Action Levels and
include 1 mg/kg for total VOCs and 10 mg/kg
for semi-volatiles, and are designed to mitigate
the threat of ground water contamination.

UPPER DEERFIELD TOWNSHIP SANITARY LANDFILL, NJ
September 30,1991
SITE HISTORY/DESCRIPTION:
The 14-acre Upper Deerfield Township Sanitary
Landfill is an inactive landfill located on a
27-acre tract of land in Upper Deerfield
Township, Cumberland County, New Jersey.
Land use in the area is primarily agricultural.
The estimated 100 people who live within one
mile of the site maintained individual water
supply wells until the early 1980's. From 1938 to
1960, Seabrook Farms, Inc., a vegetable growing
and processing company, operated the property
as a gravel pit, and later as a waste disposal
facility for its vegetative wastes. During this
time, pesticide residues and containers were
allegedly disposed of at the site. Since 1960,
Upper Deerfield Township has owned and
operated the facility as a municipal sanitary
landfill. A number of State investigations
identified VOCs including vinyl chloride,
chlorinated solvents, and mercury in excess of
Federal Drinking Water Standards in ground
water. In 1983, Upper Deerfield Township
began to supply affected residents with bottled
water, and in 1986, the township installed a
public water supply well and distribution
system. This ROD addresses ground water and
air. Because EPA investigations showed that the
ground water and soil contamination associated
with the site no longer posed a health threat
under current or likely land use conditions, there
are no contaminants of concern affecting this
site.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
no further action since previous investigations
indicated that ground water and soil
contamination associated with the site no longer
pose a health threat under current or likely
future land use conditions. However, a
comprehensive ground water and air monitoring
program will be implemented, which will
include installing additional monitoring wells
and sampling downgradient residential wells. In
addition, sediment and surface water sampling
will be conducted. The estimated present worth
cost for this remedial action is $2,380,000, which
includes an annual O&M cost of $154,000.

SITE HISTORY/DESCRIPTION:
The 1.72-acre Waldick Aerospace Devices site is
a former aerospace parts manufacturing facility
in Wall Township, Monmouth County, New
Jersey. Land use in the area is predominantly
commercial and industrial, with residential
properties located to the east. Hannabrand
Brook flows within 900 feet of the site before it
merges with another stream that eventually
drains into the Atlantic Ocean. The site overlies
a sandy silt/sand aquifer system that is a
potential source of drinking water. From 1979 to
1983, Waldick Aerospace Devices, Inc., used the
site to manufacture electroplated quick-release
pins for the aerospace industry. For at least the
first 3 years of operation, wastewater containing
metals and organic solvents was discharged
directly onto the ground. In addition, used
machine oil was allowed to drain out of
perforated drums onto the ground. As a result
of State and local inspections, a number of
investigations were conducted by EPA, which
revealed VOCs, organics, and metals in soil and
ground water in excess of MCLs. In 1985, EPA
conducted a removal action that involved
disposing of all manufacturing-related chemicals
from the facility offsite. A 1987 ROD provided
a source control remedy for soil that included
in-situ air stripping to remove VOCs, excavation
and offsite disposal of an area of metal-
contaminated soil, and decontamination or
demolition of onsite buildings. This ROD
addresses both a final remedy for soil as a
modification of the 1987 ROD, and an interim
remedial action for ground water to prevent
further ground water contaminant migration.
The modification to the 1987 source remedy is a
result of additional investigations, which
revealed that metals were widespread
throughout the site, and that the volume of
contaminated soil was less than half of the
previously estimated amount. In addition, tests
during remedial design revealed that in-situ air
stripping was inappropriate for the site. A
future ROD will address a final remedy for the
ground water contamination. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE, TCE,
and toluene; other organics; and metals
including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected modified remedy for the source
contamination at this site includes excavating
8,000 cubic yards of contaminated soil; using
onsite thermal treatment to remove organics;
treating inorganic contaminated soil using
solidification/stabilization, with backfilling or
offsite disposal of the treated soil. The selected
interim remedial action for ground water
includes installing four ground water extraction
wells in the zone of highest contaminant
concentration; using chemical precipitation to
remove inorganics, and disposing of the
resultant sludge offsite; using air stripping to
remove organics; reinjecting or infiltrating the
treated ground water into the aquifer, or
discharging it to wetland areas to help offset any
dewatering effects caused by ground water
extraction, if appropriate; and conducting ground
water monitoring. The estimated cost of the soil
remediation is $3,420,000 to $5,913,569 depending
on whether treated material is disposed of onsite
or offsite, respectively. The estimated present
worth cost for the ground water remedial action
is $5,923,372, which includes an annual O&M
cost of $705,625.
PERFORMANCE STANDARDS OR GOALS:
Ground water will be treated to achieve MCLs
and non-zero MCLGs as part of the final
remedial action. Chemical-specific clean-up
levels, therefore, were not established.

WARWICK LANDFILL, NY
June 27,1991
SITE HISTORY/DESCRIPTION:
The 13-acre Warwick Landfill is an inactive
municipal and industrial waste disposal site in
the Town of Warwick, Orange County, New
York. Land use in the area is predominantly
residential, and the site is surrounded by
woodlands and wetlands. The estimated 3,000
people who reside approximately 1.5 miles
northeast of the site use residential wells as a
source of drinking water. From 1898 until its
closure in 1978, the Warwick Landfill accepted
municipal and industrial wastes and sludge.
Landfill contamination is attributed to the
unpermitted and illegal disposal practices
conducted by waste haulers and trespassers. As
a result of reports of illegal onsite dumping in
1979, and an inspection after a property transfer
in 1984, State investigations were conducted, and
revealed soil, sediment, ground water, and
surface water contamination throughout the site.
This ROD addresses the contaminant source, the
onsite landfill, and provides an interim ground
water remedy for the first operable unit (OU1).
The final remedy for ground water (OU2) will be
addressed in a subsequent ROD. The primary
contaminants of concern affecting the soil, and
ground water are VOCs including benzene, TCE,
toluene, and xylenes; other organics including
PAHs and phenols; and metals including arsenic,
chromium, and lead.

WHITE CHEMICAL, NJ
September 26,1991
SITE HISTORY/DESCRIPTION:
The 4.4-acre White Chemical site is a former
chemical manufacturing facility in Newark, Essex
County, New Jersey. Land use in the area is
predominantly industrial and residential, with an
estimated daytime population of 12,000 within
one-quarter mile of the site. Onsite features
include five major buildings and three smaller
facility support buildings. From 1983 to 1990,
White Chemical Corporation (WCC) used the site
to manufacture acid chlorides and flame
retardant compounds. As a result of State
inspections, a number of investigations were
initiated by the State and EPA that identified
10,900 55-gallon drums containing improperly
stored hazardous substances; 150 gas cylinders;
126 storage tanks, vats, and process reactors;
12,000 laboratory-size containers; and other
miscellaneous hazardous material present onsite.
In 1989, the State conducted several site
investigations and issued notices of violation for
improper management and storage of hazardous
waste. In 1990, the State reinspected the site and
again found various violations, and ordered
WCC to clean up the site. As a result of WCC's
failure to respond to any State notices or
directives, the State initiated a removal action to
stabilize the site. After removing 1,000 drums,
the State exhausted its authorized funds and
suspended operations. Shortly thereafter, the
State requested that EPA consider conducting a
removal action at the site. Later in 1990, EPA
issued WCC a Unilateral Administrative Order
(UAO) to discontinue all site activities and
evacuate all personnel. EPA also performed
several site assessments and initiated
stabilization activities under removal authorities.
Ongoing actions include drum overpacking,
segregating incompatible substances, and
restaging containers. EPA removed an
additional 3,200 empty 55-gallon drums and
repaired the chain-link fence that secures the
property. The contents of many containers are
still unknown. This ROD addresses interim
remedial measures for surface contamination. A
future ROD will address additional remedial
measures deemed necessary as a result of a
comprehensive RI/FS. The primary
contaminants of concern identified in the tanks,
drums, and containers are VOCs including
benzene and xylenes, other organics, inorganics,
and shock-sensitive compounds.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes continuing the site stabilization
process performed during the ongoing removal
action; compiling an inventory, staging
incompatible substances, and consolidating
compatible substances for onsite temporary
storage; tranferring the contents of any container
of questionable integrity to a new container;
overpacking fuming or leaking containers;
disposing of or recycling any empty containers,
along with any extremely hazardous substances
offsite to ensure the stability of the site; possibly
mobilizing a treatment system to treat or
neutralize some of the onsite hazardous
substances; decontaminating empty tanks,
reaction vessels, and process piping, followed by
onsite storage; transporting the contaminated
material offsite to a RCRA-approved treatment
facility, to a hazardous waste disposal facility, or
to an appropriate facility for recycling or
processing; developing an emergency response
contingency plan for responding to any
emergencies that may occur during stabilization
efforts, and possibly a transportation safety
contingency plan for transporting hazardous
substances; continuing implementation of site
security measures; and conducting
environmental monitoring, and additional
investigations to fully characterize the nature
and extent of contamination in other
environmental media at the site, and to evaluate
additional remedial measures. The estimated

AVCO LYCOMING-WILLIAMSPORT DIVISION, PA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 28-acre AVCO Lycoming-Williamsport
Division site is an active manufacturing facility
in Williamsport, Pennsylvania. Surrounding
land use is primarily residential. The site
overlies a surficial glacial aquifer and a deeper
bedrock aquifer that are used as seasonal sources
of drinking water. Ground water is pumped
from the Williamsport Municipal Water
Authority (WMWA) well field located 3,000 feet
south of the site. Wetlands are located near the
site in the 100-year floodplain of Lycoming
Creek and the Susquehanna River. From 1929
until present, various manufacturing companies
including a bicycle and sewing machine
manufacturing plant, a sandpaper plant, a tool
and die shop, a silk plant, and aircraft engine
manufacturing plant have been located onsite.
Possible sources of onsite contamination include
improper waste disposal in a "dry well,"
laboratory chemical disposal in a coolant well,
spillage and dumping in metal plating areas, a
sludge holding lagoon, cutting oils from a metal
chipster sump, degreasing areas, and chemical
storage areas. The site also contains
approximately 40 underground storage tanks
that are presently being abandoned or upgraded.
In 1984, the State identified VOC contamination
in the WMWA well field. In 1985, monitoring
and recovery wells were installed onsite and
offsite to identify the source of contamination,
which was determined to be the AVCO plant. In
1986, the State approved the AVCO remedial
action plan, which included installation of an air
stripping system to treat water from three onsite
and two offsite recovery wells, and discharge to
Lycoming Creek. This remedial action remains
in effect. Between 1989 and 1991, a RI/FS study
was conducted to further characterize the
contamination and source areas. This ROD
addresses management of migration of
contaminated ground water from the onsite area.
Remediation of offsite ground water will be
addressed in a subsequent ROD. The primary
contaminants of concern affecting the ground
water are VOCs including TCE and metals
including chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and treatment of contaminated ground
water using an onsite treatment facility that
utilizes precipitation, coagulation, flocculation,
and air stripping; treating air stripper off-gases
using Best Available Technology (BAT), possibly
granular activated carbon or fume incineration;
dewatering and offsite disposal of residual
precipitation sludge and spent carbon filters;
discharging treated water onsite to surface water;
monitoring ground water; and implementing
institutional controls including land use
restrictions. The estimated present worth cost
for this remedial action is $9,300,000, which
includes an annual O&M cost of $442,900 for 30
years.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up standards are based on
the more stringent of Federal MCLs or non-zero
MCLGs, or background levels. Chemical-specific
goals were not provided.
INSTITUTIONAL CONTROLS:
Land use restrictions will be implemented at the
site.

ARROWHEAD ASSOCIATES/SCOVILL, VA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 30-acre Arrowhead Associates/Scovill site is
a cosmetic-case manufacturing and filling facility
in Westmoreland County, Virginia. Land use in
the area is predominantly agricultural, with
several businesses. Also, woodlands and
wetlands areas are located proximal to the site.
There is a small stream, Scales Branch, that
originates onsite and flows to an offsite pond
and creek. The site overlies a shallow aquifer
that is used by an estimated 500 people as a
drinking water supply. Ownership of the site
has changed hands several times. From 1966 to
1979, Scovill, Inc., and later Arrowhead
Associates (AA), used the site for manufacturing
cosmetic cases using electroplating, lacquering,
and enameling processes. Once the plating
process was complete, the solutions were
discharged to onsite settling ponds. Supernatant
from these ponds was either reused or
discharged to surface water. Bottom wastes and
small amounts of other spent materials were
stored in drums for subsequent offsite disposal.
After 1979, site operations switched to
cosmetic-case filling, and subsequently to wire
harness manufacturing. Currently, Virginia
Elastics uses the former plating area as a storage
warehouse. Numerous investigations by the
State and EPA revealed extensive soil and
ground water contamination. From 1986 to 1988,
EPA conducted a two-phased removal action at
the site. Phase I of the removal, conducted from
1986 to 1987, included removal of wastes and
various contaminated materials. Phase II,
conducted from 1987 to 1988, consisted of
treating and disposing of wastewaters, sludge,
and soil from the former settling ponds, and
offsite disposal of contaminated soil from a
drum storage area. In 1990, the ponds were
filled and graded, and erosion control measures
were installed. This ROD addresses final
remediation of soil and ground water. The
primary contaminants of concern affecting the
soil and ground water are VOCs including
benzene, PCE, TCE, toluene, and xylenes; and
metals including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
implementing in-situ vacuum extraction of
VOC-contaminated soil; onsite pumping and
pretreatment of contaminated ground water
using pH adjustment, precipitation, flocculation/
sedimentation, and filtration, followed by
treatment using air stripping and carbon
adsorption, and onsite discharge of the treated
water to Scales Branch; disposing of residual
sludge and residues from the ground water
treatment process offsite; treating off-gases from
the soil and ground water treatment systems
using carbon adsorption; and implementing
environmental monitoring, and institutional
controls including ground water use restrictions.
The estimated present worth cost for this
remedial action is $13,177,000, which includes an
annual O&M cost of $11,833,000.
PERFORMANCE STANDARDS OR GOALS!
Chemical-specific soil clean-up goals will be
determined during the remedial design.
Chemical-specific ground water clean-up goals
are based on SDWA MCLs and include benzene
5 ug/1, PCE 5 ug/1, and TCE 5 ug/1.
INSTITUTIONAL CONTROLS:
Ground water use restrictions will be
implemented to prevent the use of water from
the contaminated aquifer until the aquifer has
been remediated to acceptable levels.

BRODHEAD CREEK, PA
March 29,1991
SITE HISTORY/DESCRIPTION:
The 12-acre Brodhead Creek site is a former coal
gasification plant in the Borough of Stroudsburg,
Monroe County, Pennsylvania. The site occupies
the floodplain area at the confluence of Brodhead
and McMichael Creeks. Surrounding land use is
commercial and residential. Site features include
two earthen levees constructed to protect a
nearby sewage treatment plant from potential
floodwaters. From approximately 1888 to 1944,
the coal gasification plant was operated along
the west bank of Brodhead Creek. These
activities produced a liquid coal tar product
comprised of PAHs, which was disposed of in
an onsite open pit until the mid-194(ys. In 1980,
during construction repairs to the toe of the
flood control levee, coal tar was observed
seeping into Brodhead Creek. From 1981 to
1984, several state and federal emergency
response measures and investigations were
initiated onsite. These included installing filter
fences and underflow dams to intercept coal tar
seepage, installing a coal tar recovery pit on the
bank of Brodhead Creek, and constructing a
slurry wall to mitigate onsite coal tar migration
toward Brodhead Creek. In addition, from 1982
to 1983, the State and EPA conducted a program
designed to remove coal tar from a backwater
channel area, which involved excavating and
dewatering 900 cubic yards of sediment and
backfilling the area with clay and clean soil.
Also during this time period, the PRPs installed
recovery wells in the main coal tar pool and
subsequently removed 8,000 gallons of coal tar.
This ROD addresses contaminated subsurface
soil containing free coal tar, and provides an
interim remedy for the site. A future ROD will
address onsite ground water contamination and
provide the final remedy for the subsurface soil.
The primary contaminants of concern affecting
the soil are VOCs including benzene, toluene,
and xylenes; other organics including PAHs; and
metals including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
an in-situ innovative enhanced recovery process
which entails installing hot water injection and
extraction wells in the free coal tar areas
comprised of approximately 200 cubic yards of
subsurface soil; recovering both coal tar and
process water from extraction wells; separating
the coal tar from the process water and
disposing of the recovered coal tar at an offsite
permitted incineration facility; treating the
process water; discharging a portion of the
treated process water to Brodhead Creek, and
reinjecting the remainder of the treated water
into the subsurface soil to enhance coal tar
recovery; conducting a treatability study to
evaluate the coal tar recovery process;
monitoring ground water, sediment, and biota;
and implementing deed restrictions, and site
access restrictions such as fencing. The
estimated present worth cost for this remedial
action is $4,120,000, which includes a total O&M
cost of $1,112,000.
PERFORMANCE STANDARDS OR GOALS:
The enhanced recovery process will be applied
to the free coal tar (i.e., coal tar at 100% pore
volume saturation) areas, and will remove and
treat 60-70% of the free coal tar. This process will
prevent further leaching of contaminants into the
shallow ground water.
INSTITUTIONAL CONTROLS:
Deed restrictions will be enacted to limit future
site use.

CRYO-CHEM, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 19-acre Cryo-Chem site is a metal fabrication
facility in Worman, Earl Township, Berks
County, Pennsylvania. Land use in the area is
semi-rural, with a woodland area located
northeast of the site, and an onsite stream west
of the contaminated area. Between 1970 and
1982, chemical solvents were used at the facility
at a rate of two to three 55-gallon drums per
year. During this time, a chemical spill occurred
at Cryo-Chem, but cannot be definitely linked to
the source of contamination. Well sampling
conducted between 1985 and 1987 showed
ground water contamination in monitoring and
residential wells within 1 mile of the site, which
led to a removal action that required the
installation of activated carbon filter units in 20
affected homes. EPA has divided the site into
three operable units (OUs) for remediation. A
1989 ROD addressed OU1, the contaminated
drinking water, by providing an alternate water
supply. A1990 ROD addressed the remediation
of ground water using air stripping and carbon
absorption as OU2. This ROD addresses
contamination in soil caused by past facility
operations, which continues to leach from the
soil into the ground water system. The primary
contaminants of concern affecting the soil are
VOCs including TCA, TCE, DCA, and PCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
sampling the area to better define the extent of
the contamination; treating the contaminated soil
onsite using vapor extraction; controlling air
emissions using carbon absorption, and
disposing of, or regenerating any spent carbon;
discharging any water captured during in-situ
vapor extraction to the pump and treat system
currently under design; and conducting
confirmation soil sampling and air monitoring.
The estimated present worth cost for this
remedial action ranges from $53,500 to $66,400
based on the treatment selected. There are no
O&M costs associated with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
Although current background contaminant levels
are less than Federal standards, further
remediation was deemed necessary to prevent
additional leaching of contaminants from the soil
to the ground water. EPA intends to run the soil
vapor extraction system until it is effectively not
removing any additional VOCs. EPA does not
intend to continue remediation for OUS beyond
soil vapor extraction since it is known that the
contaminant levels in soil will be below levels
that are protective of human health.

DELTA QUARRIES/STOTLER LANDFILL, PA
March 29,1991
SITE HISTORY/DESCRIPTION:
The 137-acre Delta Quarries/Stotler Landfill site
includes a 57-acre former landfill, and is located
between the City of Altona, Logan Township
and the Village of Pinecroft, Antis Township,
Pennsylvania. Land use in the area is rural.
Several residences are approximately 35 feet east
of the landfill boundary, and wetlands areas
exist to the southeast and northeast. Residences
and businesses in the vicinity of the site rely on
private wells adjacent to the landfill for their
drinking water supply. Beginning in 1964, two
adjacent municipal landfills were operated
onsite, and in 1976 these operations were merged
into one landfill, known as the Stotler Landfill.
Delta Quarries and Disposal, Inc., purchased the
landfill and continued to operate the facility until
its closure in 1985. Reports from EPA, the State,
and previous landfill operators indicate that
municipal wastes comprise 98% of the total
landfilled wastes; however, the landfill had
accepted some industrial wastes including
organic solvents, process sludge and metals from
electroplating operation, tramp oils and residues
from sludge sedimentation basins, which have
contaminated onsite soil and ground water in the
landfill area. In 1984, the State and Delta
Quarries entered into a consent order to develop
and implement a closure plan for the landfill. In
1987, the site owners initiated the plan by
placing a 4-foot soil cap over the landfill,
vegetating the area, and installing sedimentation
controls including interceptor berms, channels,
and sedimentation basins. All elements of the
closure plan were completed except installation
of a gas venting system. This ROD addresses
onsite ground water contamination. The
primary contaminants of concern affecting the
ground water are VOCs including PCE, TCE,
and vinyl chloride; and metals including
manganese.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and onsite pretreatment of ground
water using precipitation to remove metals, if
necessary, followed by onsite treatment using air
stripping; discharging the treated water offsite to
Little Juniata River; controlling air emissions
using activated carbon; monitoring ground water
and surface water; maintaining the cap, and
installing a gas venting system; conducting
periodic site reviews; and implementing
institutional controls including deed and land
use restrictions, and site access restrictions such
as fencing. The estimated present worth cost for
this remedial action is $2,344,581, which includes
a present worth O&M cost of $1,176,989 over 30
years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up
standards are based on the more stringent of
SDWA MCLs or background levels, and include

DIXIE CAVERNS COUNTY LANDFILL, VA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 39-acre Dixie Caverns County Landfill is a
former municipal landfill in Roanoke County,
Virginia. The surrounding land is rural, with the
nearest residence located 1/2 mile from the site.
The site is situated on a steep ridge between two
valleys surrounded by heavily forested
mountains traversed by small streams. Two
unnamed headwater streams receive surface
runoff from the site, and discharge to the the
Roanoke River, which is located 2 miles
south/southeast. The landfill is currently owned
and was operated by the county of Roanoke
from 1965 until its closure in 1976. During
operation, Dixie Caverns Landfill accepted an
estimated 440,000 cubic yards of municipal and
industrial wastes including refuse, scrap metal,
flyash, and sludge. In 1983, EPA investigations
identified several disposal areas including a
discarded drum area, a sludge pit, and a large
flyash pile, which contained elevated levels of
metals. In 1987, EPA conducted a removal
action that addressed the drum and sludge areas;
however, removal of the flyash was suspended
upon EPA's recommendation. In 1987, the
County developed a removal work plan
proposing a proprietary stabilization process to
treat the flyash, and the plan was approved in
1988 with remediation levels set by EPA.
Questions concerning the regulatory status of the
waste caused delay in implementing the work
plan. At that time, EPA recommended
suspension of further removal activity pertaining
to the flyash because of uncertainty as to
whether or not the County's plan would meet
Federal and State requirements. This ROD
addresses the flyash at the site as operable unit
1 (OU1). Future RODs will address other
remedial actions based on RI/FS investigations.
The primary contaminants of concern affecting
the debris are metals including lead, cadmium,
and zinc.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes excavating and transporting
approximately 9,000 cubic yards of flyash offsite
to an EPA-approved High Temperature Metals
Recovery Technology facility for treatment and
subsequent reuse; and implementing State dust
and erosion and sediment controls during flyash
excavation. The present worth cost for the
remedial action is $3,927,158. There are no O&M
costs associated with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific flyash clean-up goals are based
on onsite disposal criteria developed by EPA
during the recent K061 LDR ruling, and include
lead 0.095 mg/kg and cadmium 0.032 mg/kg.

DORNEY ROAD, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 27-acre Dorney Road site is a landfill in
Upper Macungie Township, Lehigh County,
Pennsylvania. Land use immediately
surrounding the site is rural, residential, and
agricultural. Approximately 7 acres of wetlands,
including ponded areas, are scattered throughout
the site, with the greatest concentration of these
areas in the north-central part of the site. The
estimated 20 residents living within 1/4 mile of
the site use ground water as the primary source
of potable water. Prior to 1959, the site was
used as an open pit iron mine. From 1959 to
1979, municipal and industrial wastes were
disposed of in the onsite abandoned iron mine
pit and on the surrounding land. In 1970, the
State requested that the landfill be compacted
and covered, but the owners failed to comply.
State inspections during 1970 to 1972 identified
a variety of wastes disposed of at the landfill
including electric utility plant sludge, battery
casings, barrels of petroleum products, and
asbestos flooring waste. The site was closed in
1978 because the owners were unable to acquire
a landfill permit to renew disposal operations.
In 1986, EPA performed an emergency removal
action to regrade a portion of the site to collect
and contain onsite surface run-off. Although a
soil cover was applied to portions of the site, the
landfill was never graded and capped, and
onsite waste continues to be exposed in areas.
Seepage of leachate from landfill wastes is the
principal source of ground water contamination.
A 1988 ROD addressed operable unit 1 (OU1)
and provided for elimination of onsite ponded
water; regrading and multi-layer capping of the
site; installing run-on/run-off controls; ground
water monitoring; and implementing
institutional controls including deed restrictions
and site access restrictions including perimeter
fencing. In 1991, EPA issued an Explanation of
Significant Differences (BSD) for OU1 requiring
mitigation of wetlands areas affected during cap
construction. This ROD addresses ground water
contamination as OU2, and provides a final
remedy for the site. The primary contaminants
of concern affecting the ground water are VOCs
including benzene and TCE; and metals
including chromium and lead.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
providing wellhead treatment using carbon
adsorption for the private wells of affected
residences, and ground water monitoring. The
estimated present worth cost for this remedial
action is $274,040, which includes an annual
O&M cost of $14,410.
PERFORMANCE STANDARDS OR GOALS:
ARAR waivers will be issued for State standards,
specifically those requiring remediation of onsite
ground water to background levels and
remediation of offsite ground water to MCLs on
the basis of technical impracticability. In
addition, data indicate that ground water
contamination appears to be naturally
attenuating. Ground water action clean-up levels
are based on MCLs, risk levels, and State
standards, and include benzene 5 ug/1, TCE
5 ug/1, chromium 100 ug/1, and lead 15 ug/1.

SITE HISTORY/DESCRIPTION:
The 25-acre Eastern Diversified Metals (EDM)
site is a former metals reclamation facility in
Rush Township, Schuylkill County,
Pennsylvania. Land use in the area is
predominantly agricultural with small pockets of
residential, commercial, and undeveloped land.
In addition, a small westward moving stream
traverses the site's southern border and
discharges into the Little Schuylkill River,
250 feet west of the site. Before 1966, the site
was owned by an aluminum manufacturing
facility. From 1966 to 1977, EDM reclaimed
copper and aluminum from metal wire and cable
in an onsite processing building. Plastic
insulation surrounding the metal wire and cable
was mechanically stripped and separated, and
the waste insulation was disposed of behind the
processing facility. Over time, the insulation
material formed a residual pile of "plastic fluff,"
the most distinctive site feature. In 1974, the
State required EDM to install a leachate
collection and treatment system onsite to
monitor, collect, and treat leachate emanating
from the fluff pile. Because of high BOD
concentrations in the leachate, a secondary
treatment was designed and installed, channeling
leachate using drainage ditches and collection
trenches through an equalization lagoon to an
onsite treatment plant. In 1977, EDM terminated
operations, and in 1979 and 1980, residents
complained of odors from the site and expressed
health concerns. Subsequent State and EPA
investigations from 1983 to 1985 determined that
the fluff piles, soil, sediment, leachate, and
ground water were contaminated by VOCs, other
organics, and metals. This ROD addresses two
of three operable units (OUs) at the EDM site.
This ROD provides a final remedy for "hot spot"
fluff and soil areas, metal-contaminated sediment
and soil, and miscellaneous debris as OU1; and
provides an interim remedy for contaminated
ground water as OU2. Future RODs will
address the final selected actions for ground
water (OU2), and the remainder of the fluff pile
(OU3). The primary contaminants of concern
affecting the soil, sediment, debris, ground
water, and surface water are VOCs including
TCE; other organics including dioxins and PCBs;
and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
removing 480 cubic yards of soil contaminated
with lead above Federal target levels from
drainage ditches; excavating and incinerating,
either onsite or offsite, 500 cubic yards of
dioxin-contaminated fluff and 5,160 cubic yards
of PCB-contammated fluff and soil in excess of
Federal target levels; consolidating the onsite
scattered fluff with the remainder of the fluff
pile; removing 120 cubic yards of sand/silt/clay
stream sediment contaminated by metals above
Federal target levels; conducting toxicity testing
on incinerator residuals, miscellaneous debris,
and possibly on soil and sediment depending on
type of disposal or containment; disposing of
incinerator residuals in an offsite municipal
landfill or consolidating these with the remaining
fluff pile onsite, if residuals pass the toxicity test;
if residuals fail the toxicity test, treating with
stabilization prior to disposal; disposing of onsite
soil and/or sediment passing the EP toxicity test
in an offsite municipal landfill; or if soil and
sediment fail an EP toxicity test, stabilizing prior
to disposal; disposing of miscellaneous debris
passing the toxicity test in an offsite municipal
landfill; or if miscellaneous debris fails the
toxicity test, disposing of these materials in an
appropriate RCRA unit; upgrading surface water
run-on/run-off controls; installing a ground
water collection trench parallel to the existing
trench to relieve overburden ground water flow;
treating ground water and leachate at an onsite

clarification, discharge, and biological treatment,
with onsite discharge; upgrading the wastewater
treatment facility and existing equalization
lagoon, or constructing a new lagoon to meet
Federal requirements; and further studying the
practicability of deep ground water restoration.
The estimated present worth for this remedial
action is $12,429,000, which includes a present
worth O&M cost of $1,428,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific goals for soil, sediment, and

FIRST PIEDMONT QUARRY 719, VA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 4-acre First Piedmont Quarry 719 site is an
inactive industrial and agricultural landfill
located north of the city of Danville in
Pittsylvania County, Virginia. Land in the area
consists of open space and woodlands, with
residential areas located to the south. The
estimated 1,893 people living within 2 miles of
the site obtain drinking water from wells or
springs. Two small ponds and a wetlands area
are located onsite. In addition, the landfill is a
ground water discharge area for an underlying
aquifer draining through the wetlands to
Lawless Creek, which runs 1,400 feet northwest
of the quarry. The site originally operated as a
quarry for crushed stone. From 1970 to 1972,
industrial and agricultural wastes were landfilled
in the 2-acre quarry area of the site. Wastes
include hundreds of buried drums; tires; scrap
rubber; approximately 15,000 gallons of a
mixture of MS-20 (a floor degreaser containing
PCE^ water, carbon black, and detergent;
off-specification batch materials containing trace
amounts of lead oxide; soil; tobacco scraps; and
wood. The landfill contains approximately
65,000 cubic yards of industrial and agricultural
wastes and 3,000 cubic yards of soil. Two
additional waste areas, the Carbon Black Pile
awi the Waste Pile, have been identified onsite
near the western edge of the landfill. The
Carbon Black Pile contains 100 cubic yards of a
tire reinforcement additive and contaminated
soil, and the Waste Pile contains 10 cubic yards
of steel and nylon cords, glass, waste rubber
strips, and contaminated soil. In 1972, the State
ordered waste disposal operations to cease as a
result of a fire on the landfill. This ROD
provides a final remedy for all site media
including the landfill material, leachate, the
Carbon Black Pile and Waste Pile, and the
contaminated Northern Drainage soil and
sediment. The contaminants of concern affecting
the site are metals including arsenic, lead,
barium, antimony, and zinc.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and disposing offsite 1,080 tons of
waste from the Carbon Black and Waste Piles
along with the contaminated soil and sediment
from the Northern drainage areas; performing a
TCLP of excavated material to determine if it is
RCRA characteristic waste, and if so, solidifying
and stabilizing the excavated material prior to
offsite disposal; filling the excavated Carbon
Black and Waste Pile areas with clean soil;
disposing of 30-40 drums from the surface of the
landfill at a RCRA Subtitle C treatment facility;
decontaminating and disposing of surface debris
at an approved landfill; constructing a RCRA-cap
and an associated leachate collection system over
the 2-acre landfill area; covering the cap with
6 inches of soil and contouring soil to promote
run-off, and revegetating the area; constructing
run-off control berms in the Northern Drainage
areas to lessen landfill cap run-oŁfs; pretreating
leachate, if necessary, prior to transporting to a
POTW, or constructing an onsite treatment
system with onsite discharge to surface water if
the POTW will not accept the leachate; draining
the north and south ponds, and transporting and
discharging pond water offsite to a POTW;
monitoring ground water and conducting
bioassays to assess the effectiveness of the
removal of the Carbon Black Pile and Waste Pile
on the reduction of contaminant levels in the
Southern Drainage; and implementing
institutional controls including deed restrictions,
and site access restrictions such as fencing. The
estimated present worth cost for this remedial
action is $2,154,000, which includes an annual
O&M cost of $66,200.

GREENWOOD CHEMICAL, VA
December 31,1990
SITE HISTORY/DESCRIPTION:
The 5-acre Greenwood Chemical site is a former
chemical manufacturing facility in Newtown,
Albemarle County, Virginia. Land use in the
area is mixed residential and agricultural.
Onsite features include several buildings, storage
sheds, a buried drum area, and seven former
treatment lagoons. All residents who reside
within 3 miles of the site are completely
dependent on the ground water underlying the
site for their drinking water supply. From the
1950's to 1985, either Cockerille Chemical
Company or Greenwood Chemical Company
used the site for manufacturing chemicals for
industrial, agricultural, pharmaceutical, and
photographic purposes. The companies stored,
treated, and disposed of chemicals onsite. In
1985, operations ceased at the facility following
an explosion and fire. EPA investigations that
were conducted after this fire identified elevated
levels of cyanide, SVOCs, and VOCs in lagoons
and ground water. In 1987, EPA removed
buried and surface drums and containers of
chemicals from the site, along with the sludge
associated with three of the onsite lagoons. A
1989 ROD provided for offsite incineration,
solidification and/or disposal of 4,500 cubic
yards of contaminated soil, and removal of
containerized chemicals. An explanation of
significant differences issued in 1991 authorized
the removal of three process buildings. This
ROD addresses the contaminated ground water
and surface water as operable umt 2 (OU2) and
provides an interim remedy. A future ROD will
address additional contamination of onsite soil.
The primary contaminants of concern affecting
the ground water and surface water are VOCs
including benzene, PCE, TCE, and toluene;
SVOCs including naphthalene; and metals
including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
onsite pumping and treatment of contaminated
ground and surface water using a treatment
system consisting of precipitation, sedimentation,
filtration, and UV/oxidation, followed by
discharging the treated water onsite to surface
water; treating onsite sludge residuals from the
ground water treatment process, if necessary,
prior to offsite disposal in a landfill; and
monitoring ground and surface water. The

HALBY CHEMICAL, DE
June 28,1991
SITE HISTORY/DESCRIPTION:
The 14-acre Halby Chemical site encompasses a
chemical storage facility and associated
warehouses in Wilmington, New Castle County,
Delaware. Land use in the area is primarily
industrial. Storm water run-off from the site
generally flows toward a drainage ditch which
discharges into the Christina River. From 1948
to 1977, the Halby Chemical Plant process plant
area was used to produce sulfur compounds,
and until 1969, a portion of the site was used to
store arsenic-containing pyrite ore. From 1948 to
1964, the plant discharged all liquids into an
adjacent marsh or lagoon, which drained into the
Lobdell Canal before emptying into the Christina
River, From 1964 to 1975, the plant acid
wastewater was discharged to the public sewers.
From 1975 to 1977, the owners periodically
diverted the acid wastewater flow from the
county sewer system to its pilot plant, and the
treated wastewater was discharged to the lagoon.
In July of 1977, the facility was issued a NPDES
permit to discharge cooling water and effluent
from the process plant treatment plant. The
plant then closed in August 1977. Since 1977,
Brandywine Chemical Company has used the
site to receive and distribute bulk chemicals. As
a result of citizen complaints about lagoon
overflow, hydrogen sulfide-like odors, and
numerous spills, a number of investigations were
conducted by the State and EPA beginning in
1983, which identified leaking drums and stained
soil. Analyses of samples taken during this site
investigation revealed VOCs, organics, metals,
and other carcinogenic compounds in the soil.
This ROD addresses the first of two operable
units (OUs) and provides a final remedy for soil
and debris in the process plant area.
Contamination of air, surface water, ground
water, and sediment in the marsh and lagoon
areas will be addressed in a subsequent ROD as
OU2, The primary contaminants of concern
affecting the soil and debris are VOCs including
benzene, TCE, toluene, and xylenes; other
organics including PAHs; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
consolidating debris onsite or disposing of all
debris offsite; excavating and stabilizing the top
6 inches of approximately 10,300 cubic yards of
contaminated surface soil in the process plant
area, followed by replacing the stabilized soil
onsite; capping the approximately 5,800 square
yards residuals area with an asphalt cap;
conducting soil monitoring; and implementing
institutional controls including deed restrictions.
The estimated present worth cost for this
remedial action is $1,586,000, which includes an
annual O&M cost of $43,000.
PERFORMANCE STANDARDS OR GOALS:
The clean-up goals for soil contaminants
including arsenic and carcinogenic PAHs are set
at background levels. Additional sampling and
analysis is required to ascertain background
levels; however, approximate goals include
arsenic 10 mg/kg and carcinogenic
PAHs 1.2 mg/kg.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
post-closure use of the property and possible
damage to the cap.

HAVERTOWN POP, PA
September 30,1991
SITE HISTORY/DESCRIPTION;
The 12- to 15-acre Haver town PCP site consists
of a former wood treatment facility and an
adjacent industrial facility in Haverford
Township, Delaware County, Pennsylvania.
Land use in the area is mixed residential and
industrial. Naylors Run, a creek that drains the
entire site, flows into Cobbs Creek, which joins
Darby Creek before entering the Delaware River.
Only three families who reside more than one
mile from the site use the ground water as their
drinking water supply. From 1947 to 1991,
National Wood Preservers (NWP) used the site
for treating wood. Treated wood was air dried
on drip racks in dirt areas around the site and
stored in a dirt-covered storage yard. Chemicals
were stored in several tanks adjacent to the
facility. It has been estimated that up to
1 million gallons of spent wood preservatives
were dumped into a nearby drip well. This
disposal practice is believed to be a primary
source of contamination to ground water and,
ultimately, Naylors Run. From 1962 through
1989, the State conducted a number of
investigations, which revealed PCP, oils, PAHs,
dioxin, heavy metals, VOCs, and phenols in
ground and surface water. In 1976, EPA
initiated a response action, which included
ground water pumping and treatment, installing
filter fences, sealing a sanitary sewer, and an
attempt to grout two sewer pipes which
discharged into Naylors Run. Currently,
contaminated ground water still discharges into
Naylors Run from a storm sewer pipe. A 1989
ROD addressed operable unit 1 (OU1), the
cleanup of wastes staged onsite from previous
investigative actions, and the interim remedial
measure of designing and installing an oil/water
separator at the storm drain outlet along Naylors
Run. This ROD addresses an interim remedy for
shallow ground water contamination, as OU2. A
subsequent ROD will address sediment
contamination in Naylors Run, soil
contamination onsite, potential deep ground
water contamination from onsite soil, and
surface water and sediment contamination due
to run-off from onsite soil, as OU3. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, TCE,
toluene, and xylenes; other organics including
dioxin, oils, PAHs, PCP, and phenols; and metals
including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes installing two free product
recovery wells with floating free product
skimmers onsite; installing a shallow ground
water collection drain and pumping station, as
well as additional ground water wells to monitor
shallow ground water; rehabilitating the existing
storm sewer to reduce infiltration by lining the
sewer, followed by directing all shallow ground
water collected to the existing oil/water
separator; constructing an onsite ground water
treatment plant, which will include chemical
precipitation to remove inorganic compounds,
with either a powdered activated carbon
treatment (PACT) system or an advanced
oxidation process (AOP), and granular activated
carbon treatment as a reinforcement for the
PACT or AOP to remove organics and destroy
dioxins; treating effluent from the oil/water
separator using the new treatment plant;
discharging the effluent from the treatment plant
onsite to surface water; treating and disposing of
any residuals offsite; and ground water
monitoring. The estimated present worth cost
for this remedial action ranges from $10,036,000
to $12,177,000, which includes an annual O&M
cost ranging from $485,500 to $595,000 for

HEBELKA AUTO SALVAGE YARD, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 20-acre Hebelka Auto Salvage Yard site is an
automobile junkyard in Weisenberg Township,
Lehigh County, Pennsylvania. Land use in the
area is predominantly agricultural, with four
residential properties close to the site. The site
is located within the headwaters of the Iron Run
subdrainage basin. From 1958 to 1979, and again
from 1989 to present, the site was used as an
automobile junkyard and for salvage operations.
Scrap iron was recovered from used storage
tanks that were disposed onsite, some of which
still contained organic chemicals. In addition,
during the past 10 to 15 years, approximately
1,000 cubic yards of used battery casings have
been disposed of onsite in two piles, along with
empty storage tanks and drums, junked cars,
and miscellaneous scrap metal. In 1985, EPA
investigations identified elevated levels of lead
and chromium in soil and sediment. A 1989
ROD addressed remediation of site areas with
lead concentrations exceeding 560 mg/kg in soil,
as well as the piles of scrap battery casings
above these soil areas. The ROD also provided
for removal and recycling of the battery casings,
and excavation and treatment of soil using
cement- or lime-based fixation processes. This
ROD was developed to address soil outside of
the high lead concentration areas, ground water,
surface water, and air. However, because site
investigations have found no evidence of
contamination in the media addressed in this
ROD, there are no contaminants of concern.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
no further action other than monitoring ground
water and surface water of Iron Run annually,
and a bioassessment of the creek. The estimated
present worth cost for this remedial action is
$66,300, which includes an annual O&M cost of

HELEVA LANDFILL (AMENDMENT), PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 25-acre Heleva Landfill site is a former
sanitary landfill in North Whitehall Township,
Lehigh County, Pennsylvania. Land use in the
area is predominantly rural with scattered
residences. The estimated 150 people who reside
within one-quarter mile of the site used the
ground water underlying the site as their
drinking water supply prior to 1986. From 1967
to 1981, the Heleva Landfill accepted municipal
and industrial wastes, which included large
volumes of liquid TCE. As a result of Heleva's
denied requests for solid waste permits and
refusal to implement a State-ordered
biostimulation project, the State closed the
landfill in 1981. A number of subsequent State
investigations revealed ground water
contamination by VOCs, other organics, and
DNAPLs at levels that exceeded State and
Federal ground water limits. A 1985 ROD
addressed onsite ground water contamination
and provided for extending an existing water
main; capping the entire landfill; constructing
surface water diversions and gas venting
systems; constructing an onsite ground water
treatment facility; establishing a pumping and
treating system for the contaminated
neargradient ground water; and ground water
sampling and monitoring. Construction of all of
these major remedial activities has been
completed except for the ground water extraction
and treatment component. This ROD amends
the ground water component based on data from
the 1989 predesign study which determined that
collection of downgradient ground water is
technically feasible. The primary contaminants
of concern affecting the ground water are VOCs
including benzene, PCE, TCE, toluene, and
xylenes.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes continuing with the selected remedy
from the previous ROD but replacing the ground
water portion of the remedy with extraction of
neargradient ground water to contain the highly
contamination dissolved plume in the vicinity of
DNAPL contamination in the ground water;
pumping and onsite treatment of the
downgradient portion of the aquifer, and
discharging the treated ground water onsite to
surface water. The estimated present worth cost
for this amended remedial action is $40,950,000,
which includes an annual O&M cost of
$1,848,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Downgradient ground water will be remediated
to State background levels including benzene
0.2 ug/1, PCE 0.03 ug/1, TCE 0.03 ug/1, and
toluene 0.2 ug/1. The State and Federal ARARs
for remediation of neargradient ground water to

HELLERTOWN MANUFACTURING, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 8.64-acre Hellertown Manufacturing site is
an inactive spark plug manufacturing facility in
Northampton County, Pennsylvania,
approximately 1.5 miles south of Bethlehem.
The site is bordered by commercial and
residential areas, highway and railroad
transportation corridors, Saucon Creek, and a
wetlands area. Onsite features include a
124,000-square-foot building, and five lagoons
totaling 500,000 cubic feet. From 1930 to 1975,
chemical wastes including TCE, zinc plating
waste, chrome dip waste, cleaners, and cutting
oils generated during plating and degreasing
processes were disposed of onsite in the unlined
lagoons. Waste from these activities then seeped
into the local soil and rock strata. In 1976, after
the facility began discharging treated wastewater
into the municipal sewer system, the lagoons
were backfilled, closed in place, and covered
with topsoil. The material used to backfill the
lagoons included rejected spark plugs,
demolition material from road-building activities,
and soil excavated during construction of the
nearby Bethlehem wastewater treatment plant.
Studies conducted in 1990 identified
contamination by VOCs, metals, and organic
compounds in lagoon backfill, soil, and in onsite
ground water. The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene, DCE, PCE, TCE, vinyl
chloride, and xylenes; other organics including
PAHs; and metals including chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the former 3.5-acre lagoon area with an
impermeable asphalt and clay cover; pumping
and onsite treatment of ground water using air
stripping; removing solids using a settling tank
or clarifier followed by filtration; discharging the
treated effluent onsite to Saucon Creek;
long-term ground water monitoring; controlling
surface water run-off; and implementing
institutional controls including deed restrictions.
The estimated present worth cost for this
remedial action is $2,250,000.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals are based on
SDWA MCLs or State background
concentrations, whichever is the more stringent.
Chemical-specific ground water clean-up levels
include benzene 0.2 ug/1 (State background),
PCE 0.03 ug/! (State background),
TCE 0.12 ug/1 (State background), and vinyl
chloride 0.18 ug/1 (State background).
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prohibit
excavation of contaminated soil and the use of
onsite ground water for domestic purposes.

INDUSTRIAL DRIVE, PA
March 29,1991
SITE HISTORY/DESCRIPTION:
The 30-acre Industrial Drive site is an active
sanitary landfill and industrial facility in
Williams Township, Northampton County,
Pennsylvania. Land use in the area is industrial,
residential, and agricultural. The site contains
active and inactive sanitary landfills as well as
active, inactive, and abandoned industrial
facilities. The Lehigh River and Lehigh Canal
are located northwest of the site, and a portion
of the site rests upon the trace of a thrust plane
known as the Musconetcong Fault. These
conditions have created a complex geologic
setting in which ground water flow is governed
by topography. Prior to 1961, the site was used
for iron ore mining, industrial activities, and
agricultural purposes. In 1961, sanitary landfill
operations began onsite, and the site accepted
municipal solid waste for disposal in an unlined
landfill. By 1980, the landfill had expanded to 30
acres. In the late 1970's, local residents alleged
that the now inactive unlined landfill had
accepted hazardous wastes that had
contaminated local drinking water wells. Waste
disposal in the unlined landfill ceased in 1986,
but closure of the landfill has not been
completed. In 1986, the State issued a permit for
a 10-acre expansion of the landfill, which
included a liner and leachate collection system.
This expansion landfill is currently active, but
there are no plans to further expand the landfill
area. Contamination in local ground water wells
was first detected in 1983. Subsequently, the site
has been divided into two operable units (OUs)
for remediation. A 1986 ROD addressed OU1,
and provided for an alternate water supply by
connecting numerous private well users to an
existing municipal water supply. This ROD
addresses QU2, the contaminated ground water
and the low-level threat caused by the unlined
municipal landfill. The primary contaminants of
concern affecting the soil, debris, and ground
water are VOCs including benzene, PCE, and
TCE; other organics; and metals including
chromium and lead.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
closing and capping the unlined landfill area
with a clay or synthetic cap; onsite pumping and
treatment of contaminated ground water using
an air stripper, followed by carbon adsorption
with onsite discharge of the treated ground
water to the Lehigh River; regenerating spent
carbon offsite; and long-term monitoring of the
closed landfill and ground water. If the selected
remedy cannot meet the specified remediation
goals, a contingency remedy will be
implemented to prevent further migration of the
"plume, which will include a combination of
containment technologies including ground
water extraction and treatment, and institutional
controls. The estimated present worth cost for
this remedial action is $12,775,000, which
includes an annual O&M cost of $536,000 for
years 0-1 and $498,000 for years 2-45. There will
be an additional O&M cost of $20,000 every
5 years.
PERFORMANCE STANDARDS OR GOALS:
The goal of this remedial action is to remediate
ground water to background levels as specified
by the State Hazardous Waste Management
Regulations. Chemical-specific goals include
benzene 0.2 ug/1, PCE 0.03 ug/1, TCE 0.03 ug/1,
chromium 50 ug/1, and lead 5 ug/1.

McADOO ASSOCIATES, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 9-acre McAdoo Associates site is an inactive
strip and deep mining facility located in Kline
Township, Schuylkill County, Pennsylvania. The
site consists of two locations: the 8-acre
McAdoo-Kline Township (MKT) location, and
the 1-acre McAdoo-Blaine Street (MBS) location.
The MKT location is situated at the site of an old
(subsurface and surface strip) coal mine, and
land adjacent to this location is industrial,
abandoned, or contains reclaimed mine areas.
The shallow aquifer at the MKT location consists
of ground water-filled mine workings and other
subsurface voids beneath the MKT location,
collectively called the "mine pool." The mine
pool discharges at the Silverbrook discharge to
the upper reaches of the Little Schuylkill River.
Both the mine pool and the river have been
severely affected by acid mine drainage. The
MBS location is adjacent to a residential area and
a mine spoil reclamation site, and is presently
covered with gravel and used for vehicle storage.
From the 1880's to the 1960's, strip and deep
mining of anthracite coal occurred at the MKT
location. Two rotary kiln furnaces and an
upright liquid waste incinerator were installed
onsite between 1975 and 1976 to reclaim metals
from waste sludges, reportedly using waste
solvents as fuels. In 1979, EPA ordered the MKT
location to close because of numerous
environmental compliance problems. At the
time of closure, the location contained an
incinerator, a garage and offsite trailer, 6,790
drums of hazardous waste, four above-ground
15,000-gallon storage tanks, three above-ground
10,000-gallon tanks, and miscellaneous debris.
The MBS location was used for the storage of
waste oil and hazardous waste in five
underground tanks. Activities at the MBS
location were stopped by EPA in 1979. As a
result of Federal investigations, all drums and
site features were removed from the MKT
location between 1981 and 1988. A 1984 Initial
Remedial Measure (IRM) for the MBS location
provided for removal of underground tanks and
contaminated soil, and a 1985 ROD addressed
remediation of soil contamination at the MKT
location. This ROD addresses sediment, ground
water, and surface water at the MKT location,
and ground water at the MBS location. EPA has
determined that no further remedial action other
than that already implemented at the site is
required to ensure protection of human health
and the environment; therefore, there are no
contaminants of concern.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site is no
further action because previous interim remedial
activities were adequate to protect human health
and the environment. Ground water monitoring
at the MKT and MBS locations will be
performed, including expanding the ongoing
water quality monitoring program at the MKT
location, and installing four ground water
monitoring wells at the MBS location. The
estimated present worth cost for this no action
remedy with ground water monitoring is
$503,540, which includes a present worth O&M
cost of $434,000 for 30 years.

MID-ATLANTIC WOOD PRESERVERS, MD
December 31,1990
SITE HISTORY/DESCRIPTION:
The 3-acre Mid-Atlantic Wood Preservers
(MAWP) site is a wood treatment facility in
Harmans, Anne Arundel County, Maryland.
Land use in the area is predominantly industrial
and residential, and a wetland area traversed by
Stony Run Creek lies 600 feet west of the site.
Since 1974, the facility has been used for
pressure treatment of lumber using chromate
copper arsenate (CCA) as the wood preservative.
The site is divided into two areas: a Treatment
Yard on the eastern half of the site, and Storage
Yard on the western half. The Treatment Yard
contains CCA storage tanks, a pressure cylinder,
and a drip pad area. In 1978, the county
determined that water in a shallow residential
well downgradient of the site was contaminated
with high levels of hexavalent chromium.
Subsequent investigations by the State in 1978
revealed that soil and ground water
contamination by chromium and arsenic was the
result of an overflow pipe from a CCA storage
tank. Under an agreement with the State,
MAWP removed 26 cubic yards of contaminated
soil beneath the overflow pipe, modified the
CCA storage system, and installed a concrete
drainage pad to collect drippings and reduce
future contamination. However, offsite
investigations by EPA in 1983 identified elevated
levels of arsenic and chromium in ground water.
Further EPA and MAWP studies documented
that onsite arsenic-contaminated soil, the result
of removing treated wood prematurely from the
drip area before it had dried, was the principal
threat. In addition, these studies identified
approximately 5,200 cubic yards of degraded
soil, to an average depth of 2 feet, in the
Treatment Yard drip pad area and in the western
most third of the Storage Yard. Residential
ground water metal contamination levels were
found to be at much lower levels than detected
in earlier investigations; arsenic was not
detected, and chromium was detected above the
MCL in only one well. This ROD addresses
contaminated onsite soil and ground water. The
primary contaminants of concern affecting the
soil and ground water are metals including
arsenic and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and stabilizing approximately
20 cubic yards of onsite soil contaminated with
arsenic levels greater than 1,000 mg/kg (referred
to as hot spots), followed by offsite disposal;
capping the remaining soil with arsenic
concentrations between 10 mg/kg and
1,000 mg/kg with an asphalt/concrete cap;
constructing an enlarged and roofed drip pad,
which is consistent with new wood treating
regulations; allowing natural attenuation to
lower chromium levels in ground water;
monitoring sediment ground water, surface
water, and air; and implementing institutional
controls including deed restrictions. The
estimated present worth cost for this remedial
action is $322,400, which includes an annual
O&M cost of $6,500 for 30 years.
PERFORMANCE STANDARDS OR GOALS;
Chemical-specific goals for soil are based on
achieving a 10"5 cancer risk level. The
chemical-specific goals for ground water are
based on Federal MCLs including chromium
50 ug/1. EPA feels that MCLs will be achieved
by natural attenuation within 3 months after
construction is completed.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to ensure
that the containment components are not
compromised by future property use.

MIDDLETOWN AIRFIELD, PA
December 17,1990
SITE HISTORY/DESCRIPTION:
The 500-acre Middletown Airfield site is a
former military airfield located between the
towns of Highspire and Middletown in Dauphin
County, Pennsylvania. Land in the area is used
predominantly for industrial and commercial
purposes. Several onsite wetlands areas, as well
as the floodplain of a small stream, have been
identified onsite. From 1898 to 1917, the site was
operated by the U.S. Army as a basic training
camp. Subsequently, the site was used as an
airfield by the Army/Air Force from 1918 until
all onsite military operations ceased in 1966. Site
features include several private manufacturing
companies, an inactive landfill, and the
Harrisburg International Airport (HIA). The site
was divided into five distinct study areas where
soil, sediment, ground water, and surface water
investigations were conducted. These five study
areas are: (1) the 30-acre runway area where,
during the mid-1940s through 1956, wastes from
base operations were either incinerated or placed
in a landfill; (2) the 150-acre industrial area
where industrial operations such as paint
stripping and metal finishing were conducted by
the Air Force; (3) the 1-acre fire training pit area
where combustible wastes were burned during
military training exercises; (4) the 7-acre north
base landfill area where construction debris and
miscellaneous drums were disposed of from 1950
to 1956; and (5) the Meade Heights housing area
where, prior to housing construction, wastes may
have been disposed. Based on identification of
onsite soil and ground water contamination, the
remedial action for the site was divided into five
operable units (OUs) that were slightly different
from the study areas. These OUs and their
respective media of concern are as follows:
ground water for the site (OU1); the industrial
area (soil) (OU2); the fire training pit area soil

MODERN SANITATION LANDFILL, PA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 83-acre Modern Sanitation Landfill site is an
active landfill in the Townships of Windsor and
Lower Windsor, York County, Pennsylvania.
Land use in the area is predominantly
agricultural and residential, with nearby
woodland areas. The site includes an old,
inactive, unlined 66-acre landfill area, which is
the subject of this ROD, and an adjacent active
17-acre double-lined landfill area to the north.
Other site features include borrow areas for
landfill soil cover material; ground water
extraction systems to the east, west and south of
the landfill; a wastewater treatment plant; a
landfill gas-extraction system; and a
low-permeability final cover system. Since the
early 1940's, Modern Trash Removal has used
the site for municipal, and non-hazardous and
hazardous industrial waste stream disposal
activities. Industrial waste disposed of onsite
includes inorganic production residues, pesticide
waste sludge, PCS wastes, and oil and paint
waste. In 1977, a ground water interceptor
trench was constructed to collect leachate from
the west side of the site. The collected water
currently is pumped to the onsite treatment
facility. In 1981, the State detected onsite ground
water contamination by VOCs on the western
site border, and in 1983, determined that the
western interceptor trench should be upgraded
and modified, and that quarterly sampling of
monitoring wells should be implemented to
detect the leachate seeps and the presence of
leachate constituents in ground water. As a
result, extraction wells to augment the western
interceptor trench were installed. Leachate
studies in 1985 also identified organic
contamination in the eastern site area; and, as a
result, 13 extraction wells were installed along
the eastern perimeter. Four surface
impoundments were operated onsite to treat
ground water and leachate collected by the
interceptor and extraction wells. In 1987, the
surface impoundments were clean closed, and a
replacement treatment facility, which included
metal precipitation, filtration, and air stripping,
was constructed. In addition, as of 1990,64 acres
of the 66-acre unlined landfill had been covered
with a low permeability cap. This ROD provides
a final remedy for the source of leachate seeps
and ground water constituents. The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including benzene,
PCE, TCE, toluene, and xylenes; and metals
including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
completing the low permeability cap and final
cover system over the 66-acre unlined landfill;
expanding the existing ground water extraction
system on both the eastern and western sides of
the site; maintaining the onsite wastewater
treatment facility that treats extracted ground
water with physical/chemical and biological
treatment, followed by filtration and air
stripping prior to discharge of the treated
wastewater onsite; managing the landfill gas
collection system; and continuing ground and
surface water monitoring. The present worth
cost for this remedial action is $18,078/000, which
includes an annual O&M cost of $1,175,000.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals are based on State
and Federal standards and background
contaminant levels, whichever are lower.
Chemical-specific ground water goals include
benzene 5 ug/1 (MCL), PCE 5 ug/1 (MCL), and
TCE 5 ug/1 (PMCL).

SITE HISTORY/DESCRIPTION:
The 58-acre NCR, Millsboro site is a former
manufacturing facility in Millsboro, Sussex
County, Delaware. Land use in the area is
mixed residential, agricultural, and industrial
with a small stream, Iron Branch, bordering the
site to the north and northeast. From 1965 to
1967, Dennis Mitchell Industries (DMI)
conducted manufacturing operations onsite.
Reportedly, plating activities and other processes
generated wastewater and sludge that were
stored in an onsite lagoon. NCR Corporation
purchased the plant in 1967 and manufactured
mechanical cash registers from 1967 to 1975, and
electronic terminal equipment from 1975 to 1980.
NCR's activities included chromium plating,
enameling, heat treating, and degreasing
operations using TCE. TCE and oil wastes were
disposed of offsite; and oil, grease, and paint
wastes were drummed and stored onsite prior to
offsite disposal. Waste sludge associated with
the chromium plating processes was treated
onsite and directed to onsite lagoons for
sedimentation and clarification prior to discharge
to Iron Branch. NCR also disposed of the waste
sludge in a pit along the eastern boundary.
From 1981 to 1983 under State direction, NCR
conducted onsite investigations, which revealed
ground water contamination by VOCs and
chromium above levels of concern. In 1981,
NCR excavated and disposed of offsite
approximately 315 cubic yards of lagoon sludge
and other wastes during RCRA closure of the
facility. In 1988, NCR installed a ground water
recovery well and air stripper to prevent
continuing migration of a TCE ground water
plume. This ROD addresses a final remedy for
ground water contamination. The primary
contaminants of concern affecting the ground
water are VOCs, mainly TCE; and metals
including chromium.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
pumping and treatment of contaminated ground
water using air stripping, followed by carbon
adsorption, and coagulation and filtration, if
necessary, to remove chromium; controlling air
emissions from the ground water treatment
system, if necessary; discharging the treated
water onsite to surface water and/or through
ground water infiltration galleries; conducting a
well survey to identify all wells located within a
one-mile radius of the site; conducting sediment,
ground water, and surface water monitoring;
and implementing institutional controls
including ground water use and deed
restrictions. The estimated present worth cost
for this remedial action is $4,749,000, which
includes an annual O&M cost of $859,000.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs and non-zero
MCLGs, and include TCE 5 ug/1 (MCL) and
chromium 100 ug/1 (MCL). Discharge
limitations are SDWA MCLs and non-zero
MCLGs; SDWA Underground Injection Control

OLD CITY OF YORK LANDFILL, PA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 178-acre Old City of York Landfill site is a
municipal waste landfill in Springfield
Township, York County, Pennsylvania. Land in
the surrounding area is predominantly
agricultural and wooded. The site is bounded to
the southeast and the northwest by tributaries to
Codorus Creek, and these tributaries are partially
fed by seeps discharging from the valley and
hillsides near the landfill. Ten residences located
within 1/4 mile of the site have or had ground
water from domestic water wells as their
drinking water supply. From 1961 until its
closure in 1975, the City used 56 acres of the site
as a landfill for municipal wastes; however,
some industrial waste was also disposed of at
the site. In 1978, the property was sold to
private owners. After local residents expressed
concern over water quality, the State conducted
a residential well sampling program from 1981
to 1985. VOCs were identified in six residential
wells; as a result, public water main was
installed at the site. In 1982, the State notified
the City and site owners that operation of and
existing conditions at the landfill were in
violation of the Clean Streams Act and directed
the city to conduct a site assessment to evaluate
clean-up measures. During 1987 and 1989, the
City, under a State order, installed a ground
water recovery and treatment system connected
to an air stripping tower, which has not yet
started operation. Eight onsite collection vaults
containing a total of 1,120 cubic feet of
orange-tinted sediment and water are located on
the site. These vaults are part of an old leachate
collection system that is no longer functioning.
In 1991, the owner placed a deed restriction on
the entire site to prevent ground water and
surface water usage, additional agricultural
usage, subdivision of the property, and soil
disturbance. This ROD addresses the long-term
threats to soil, ground water, and surface water
produced by the landfill and vault sediment.
The primary contaminants of concern affecting
the soil and ground water are VOCs including
benzene, PCE, and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
restoring and revegetating the soil cover in the
northeastern portion of the site; disposing of
vault sediment offsite; installing a diversion
swale along South Road; installing a ground
water recovery/treatment system using the
existing air stripper, or adding additional ones,
as needed, with onsite discharge to surface
water; installing a landfill gas venting system
with monitoring probes; maintaining perimeter
fencing at the leachate collection values; and
monitoring ground water, surface water, and
sediment. The estimated present worth cost for
this remedial action is $8,291,080, which includes
an annual O&M cost of $259,080 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Remediation of ground water will continue until
contaminant levels meet the lower of site
background levels, which are methods detection
limits; and Federal and State standards including
SDWA MCLs, proposed MCLs, and risk-based
levels.

PUBLICKER/CUYAHOGA WRECKING PLANT, PA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 37-acre Publicker/Cuyahoga Wrecking Plant
site is a former liquor and industrial alcohol
distillery in Philadelphia, Philadelphia County,
Pennsylvania. Surrounding land use is primarily
industrial, with 400,000 people living within a
1-mile radius of the site. From 1912 until 1986
when the plant closed, alcohol distilling
operations were conducted onsite. From the
1970's to 1980's, the site was also used as a
petroleum and chemical storage facility, which
utilized 440 large above-ground tanks, stored
chemicals, chemical laboratories, reaction vessels,
production buildings, warehouses, a power
plant, and several hundred miles of
above-ground process lines, many of which were
wrapped with asbestos insulation. In 1987, a
CC>2 utilization area was destroyed in an onsite
fire, which was accompanied by numerous
explosions. Subsequent onsite inspections by
EPA and the State identified leaking tanks, pits,
and process lines containing fuel oil, and
shock-sensitive explosive materials, and 7,000
gallons of reactive and flammable materials in
fermentation tanks and grain dryers. In 1987,
EPA stabilized the site by bulking flammable
and explosive materials onsite for future
disposal, disposing of highly reactive laboratory
wastes and cylinders offsite, crushing 3,100
empty drums, wrapping overhead asbestos-
covered process lines with plastic, and bagging
and storing loose asbestos materials onsite. A
1989 ROD addressed operable unit 1 (OU1) and
Provided for offsite treatment and disposal of
hazardous waste streams and chemicals
recovered from within the process lines,
demolition of the above-ground process lines,
and packaging and onsite storage of asbestos
arťd other insulation materials. This ROD
addresses a portion of OU2, specifically the
bulked asbestos stored onsite, any remaining
asbestos material attached to overhead exterior
P'pelines, and a pile of asbestos debris near a
loading pier. A subsequent ROD will address
onsite soil and ground water contamination. The
primary contaminant of concern present as
debris is asbestos, an inorganic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
removing approximately 150 cubic yards of
asbestos from overhead extraction pipes and
placing this material in plastic bags; staging this
material, along with 6 cubic yards of asbestos
from near a loading pier and 1,100 cubic yards of
bagged asbestos from previous removal and
remedial actions; and disposing of the staged
asbestos offsite. The estimated present worth
cost for this remedial action is $293,420. There
are no O&M costs associated with this remedial
action.
PERFORMANCE STANDARDS OR GOALS:
All bulked and remaining loose asbestos material
will be removed from the site. No specific clean-
up standard for asbestos was provided.

RESIN DISPOSAL, PA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 26-acre Resin Disposal site is an inactive
industrial landfill and former coal strip mining
area in Jefferson Borough, Allegheny County,
Pennsylvania. The site is bordered to the north
and west by residential areas, and to the east
and south by undeveloped land. The site
overlies a bedrock aquifer, and is also in contact
with the Pittsburgh Coal Formation, a source of
non-potable ground water. Prior to 1950, coal
strip mining operations were conducted on and
near the site. From 1950 to 1964, 85,000 tons of
process wastes consisting of petroleum and
coal-derived chemicals mixed with clay were
disposed of in a previously mined onsite area,
and earthen dikes were used to contain these
wastes. Between 1980 and 1984, private
investigations identified that contaminants from
the landfill had migrated to the Pittsburgh Coal
Formation, and the soil and perched ground
water downslope. Subsequently, the site owners
installed a leachate collection system and an
oil/water separator. EPA investigations in 1988
further characterized contaminated media and
analyzed potential contaminant pathways. This
ROD addresses source control, as well as
preventing migration of contaminated ground
water in the Pittsburgh Coal Formation. A
subsequent ROD will address any remediation of
ground water that may be necessary. The
primary contaminants of concern affecting soil,
debris, and ground water are VOCs including
benzene, toluene, and xylenes; and other
organics including napthalene, PAHs, and
phenols.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the landfill with a multi-layer cap, and
upgrading the landfill dike; relocating a sanitary
sewer located along the northeast border of the
landfill to allow future access without disturbing
the landfill cap; installing a new oil/water
separator for leachate treatment, with discharge
of aqueous phases to a POTW, and possible
offsite reclamation of NAPLs for use as an
energy source; installing a skimmer well system
to remove NAPLs from ground water for use as
an energy source; monitoring ground water and
surface water; and implementing institutional
controls including deed restrictions, and site
access restrictions such as fencing. The
estirrj-Jted present worth cost for this remedial
action is $4,348,000, which includes an annual
O&M cost of $132,000 for 30 years.

SAUNDERS SUPPLY, VA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 7.3-acre Saunders Supply site is an active
lumber yard facility in the Village of
Chuckaruck, a rural area of the City of Suffolk,
Virginia. Land use in the area is predominantly
mixed residential and commercial. The site is
composed of the Saunders Supply Company
property and a portion of the adjacent Kelly
property. Commercial establishments and
residences are to the east of the facility, and a
wooded area is to the west. From 1964 to 1991,
the Saunders Supply Company used the site to
chemically treat wood before distribution. Prior
to 1984, treated wood was placed on pallets
located directly on the ground near the wood
treating process area. Subsequently, from 1984
to 1991 when the site ceased operations, treated
wood was air-dried on a concrete drip pad.
These improper treatment and disposal processes
have contaminated onsite soil, sediment, and
ground water. Principal site features include the
treatment facilities, a former conical bum pit
area, a former earthen separation pond, and a
wastewater pond west of the site. Some
drainage from the site discharges to storm
sewers adjacent to the site boundary. After the
State investigated the site, Saunders Supply was
required to install monitoring wells, excavate the
contaminated soil around the conical burn pit
area, and install a recovery well. Treated water
from the recovery well was recycled as the
process water for the chemical treatment of
lumber. EPA conducted additional
investigations that revealed the presence of
pentachlorophenol (PCP), arsenic, and chromium
in the ground water. This ROD addresses all
media impacted by site contamination as a final
remedy. The primary contaminants of concern
affecting soil, sediment, debris, ground water,
and surface water are organics including dioxins
and PCP; and metals including arsenic and
chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
draining the wastewater from the wastewater
pond, followed by onsite or offsite treatment and
discharge; excavating, treating using
dechlorination, and offsite disposal of 700 tons of
sediment from the wastewater pond and the
former earthen separation pond; excavating,
treating onsite using low-temperature thermal
desorption (LTTD), and offsite disposal of 24,300
tons of soil and sediment from the storm sewer
exceeding 1.46 mg/kg PCP; regenerating spent
carbon from the LTTD treatment process offsite;
treating ground water during the dewatering
process prior to excavating the soil; discharging
the treated water onsite or offsite based upon
remedial design studies; testing the concrete
pads for RCRA characteristic hazardous wastes;
scarification of the top 1 inch of the concrete
pads and treating the removed material using
solidification if determined to be RCRA
characteristic waste, with subsequent offsite
disposal along with the remainder of the
concrete pads; removing and plugging
preexisting wells; cleaning and sliplining the
storm sewer; monitoring ground water; and
implementing institutional controls including
deed and ground water use restrictions. The
estimated present worth cost for this remedial
action is $20,485,000, which includes an annual
O&M cost of $15,000.
PERFORMANCE STANDARDS OR GOALS:
The chemical-specific soil clean-up level is PCP
1.46 mg/kg. If ground water is discharged
onsite, treated effluent must meet State permit
limits; or if discharged offsite, treated effluent
must meet levels set by the receiving facility.

SEALAND LIMITED, DE
September 30,1991
SITE HISTORY/DESCRIPTION:
The 2-acre Sealand Limited site, a former coal tar
treatment and recycling facility, is located in Mt
Pleasant, New Castle County, Delaware. Land
use in the area is primarily industrial and
commercial. Current site features include a
concrete slab, a one-story building, an
abandoned rail spur, a gravel road, and
miscellaneous debris. Ground water underlying
the site is used as a source of drinking water.
From 1971 until 1976, Adams Laboratory used
the site for animal fat rendering activities. The
property was subsequently sold to Conrail,
which cleaned up the property to meet State
standards in 1979. From 1982 to 1983, Conrail
leased the property to Sealand. Sealand
allegedly conducted treatment processing, and
recycling of coal to tar and off-specification
creosote wastes onsite until abandoning the site
in 1983. A1983 State investigation discovered 21
steel tanks or hoppers; a 10,000-gallon wooden
storage tank and 300 55-gallon sleel drums,
which were leaking liquids onsite; a boiler
house; and various mixing chambers and
pressure vessels on the abandoned site.
Additional studies by EPA and the State
identified orgardcs including PAHs, creosols, and
solvents in the onsite soil, drums, and tanks.
Subsequently in 1983, EPA conducted an
emergency removal action at the site and
removed offsite 240,000 gallons of organic wastes
from within the wooden and steel tanks, and 320
drums. Additionally, EPA disposed of 122 cubic
yards of solid waste, including 30 cubic yards of
wooden tank debris and approximately 50 to 92
cubic yards of sludge and contaminated material
offsite. The owner voluntarily removed 239
drums of off-specification product. In addition,
the storage tanks were cleaned and moved, and
the tank and drum storage area was capped with
clay. This ROD addresses onsite soil as the first
and final operable unit (OU1). All hazardous
materials contained in abandoned onsite tanks
and drums were disposed of offsite during the
EPA removal action, and any remaining soil
contaminants pose low risks for humans at the
site. Based on this rationale, there are no
primary contaminants of concern affecting this
site.

STRASBURG LANDFILL, PA
June 28,1991
SITE HISTORY/DESCRIPTION;
The 22-acre Strasburg Landfill site is an inactive
landfill located within a 220-acre tract of land in
Newlin and West Bradford Townships, Chester
County, Pennsylvania. The site is characterized
by hills draining toward Brandywine Creek and
its floodplain, which forms the southern and
western site boundaries. The nearest wetland is
the Briar Run watershed located 600 feet
east/southeast of the site. The 201 single-family
residences that surround the site use ground
water as a source of drinking water. Before
landfilling operations began in 1973, the site was
used as farmland. From 1978 to 1983, the
landfill accepted industrial and heavy metal
wastes and sludge. State investigations in 1979
determined that landfill operations had resulted
in excessive siltation of Briar Run. In 1980, the
State permanently prohibited the landfill from
receiving industrial waste. In 1983, the owners
were cited for violations, which they failed to
correct, and the State ordered the landfill closed.
Closure involved constructing a PVC cover and
soil and vegetation layer. Subsequent studies
detected VOCs in both onsite monitoring wells
and offsite residential wells. The State initiated
an interim action to control the leachate, which
included collection and offsite treatment of
leachate at a nearby municipal sewage plant and
installing diversions to halt leachate flow. A
1989 ROD addressed contaminated residential
wells and exposure pathways, and provided an
interim remedy to limit site access. The purpose
of this ROD is to limit direct contact and
exposure to contaminants using site access
restrictions, and to reduce further degradation of
the landfill cover. Remediation of the landfill
will be addressed in a future ROD. The primary
contaminants of concern affecting soil and debris
are VOCs including benzene, PCE, TCE, and
toluene; and metals including arsenic and
chromium.
SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes implementing site access restrictions
including fencing that will encompass the
immediate landfill area, access roads, the
sediment pond, air stripping building, and
monitoring wells; and maintaining the fence and
the existing cap. The estimated total present
worth cost for this remedial action is $823,020,
which includes an annual O&M cost of $55,405.

USA ABERDEEN - EDGEWOOD, MD
September 27,1991
SITE HISTORY/DESCRIPTION;
The 17,000-acre USA Aberdeen - Edgewood site
is a military ordnance installation in Edgewood,
Maryland. The 4.5-acre Old O-Field site, which
is the focus of this ROD, is a fenced hazardous
waste and ordnance disposal area located within
the lower half of the Gunpowder Neck in the
Edgewood area of the Aberdeen Proving
Ground. Land use in the area consists of
military testing ranges, with a mixture of
industrial, military, and civilian residential areas.
The site overlies two aquifers that drain into
Watson Creek and the Gunpowder River, which
border the site. From 1941 to 1952,
chemical-warfare agents including mustard,
lewisite, adamsite, white phosphorus, munitions,
contaminated equipment, and miscellaneous
hazardous waste were disposed of in 35 onsite
unlined pits and trenches. Studies have shown
that chemicals buried within the pits have
impacted ground water and also interconnecting
surface water in Watson Creek. From 1949 to
the mid-1970's, several decontamination and
clean-up operations were conducted as a result
of munitions explosions, which spread mustard
into the surrounding soil, air, Watson Creek, and
Gunpowder River. These operations included
the application of 1,000 barrels of
decontaminating agent non-corrosive (DANC)
containing chlorinated hydrocarbons; soaking the
field with several hundred gallons of fuel oil and
setting the field ablaze; dispersing lime into the
surrounding trees to further reduce the amount
of mustard present; and using supertropical
bleach, lime, and sodium hydroxide to destroy
chemical agents. Evidence shows that these
decontamination efforts have contaminated the
ground water with chlorinated hydrocarbons.
Subsequent remediation activities were limited to
removing and securing ordnance items on the
surface. The site has been divided into three
operable units (OUs) for remediation. This ROD
provides an interim remedy for contaminated
ground water and its effect on surface water, as
OU1. Future RODs will address contaminated
onsite soil and surface water. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCE,
and toluene; and metals including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes installing a downgradient
extraction well network; pumping and onsite
treatment of contaminated ground water using
chemical precipitation, followed by
ultraviolet-oxidation; monitoring the treated
effluent, then discharging the effluent onsite to
the Gunpowder River; and disposing of the
contaminated chemical precipitation filter cake
sludge generated during the treatment process
offsite. The estimated present worth cost for this
remedial action is $9,120,000, which includes an
estimated annual O&M cost of $466,650 for 30
years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on CWA Ambient Water Quality
Criteria, and SDWA MCLs and proposed MCLs,
and include benzene 5 ug/1 (MCL), PCE 5 ug/1

USA ABERDEEN, MICHAELSVILLE, MD
September 27,1991
SITE HISTORY/DESCRIPTION:
The 79,000-acre USA Aberdeen site, also known
as the U.S. Army Aberdeen Proving Ground
(APG), is an active military installation used
since 1917 for planning and testing weapons,
munitions, vehicles, and equipment in Harford
County, Maryland, near the head of the
Chesapeake Bay. APG is divided into two
functional areas: the 13,000-acre Edgewood Area
and the 17,000-acre Aberdeen Area, which
includes two landfills. These two areas are
divided and drained by Bush River, as well as
by numerous creeks. From 1922 to 1925, an
unknown amount of World War I white
phosphorus munitions (ordnance) was
supposedly buried offshore of the Aberdeen
Area on the western side of the upper
Chesapeake Bay. This 15-acre area, termed the
White Phosphorus Underwater Munitions Burial
Area (WPUMBA), is the focus of this ROD. The
ordnance reportedly buried at the WPUMBA
consisted of land mines, grenades, and artillery
shells; in addition, bulk phosphorus may have
been buried. In 1933, the WPUMBA was
reportedly uncovered by a hurricane, resulting in
a large waterfowl kill. However, no evidence of
a disposal site at the WPUMBA was observed in
historical or aerial photographs, and only one
reference to the disposal area has been found. In
addition to background searches, EPA conducted
extensive electromagnetic and core sampling
studies of the WPUMBA from 1988 to 1989.
Sample results revealed only trace amounts of
white phosphorus and only sporadic magnetic
objects in sediment, and no phosphorus in
surface water. Hence, no effective remedial
action is possible at the site. Future RODs may
be warranted if contamination is found.
Therefore, there are no primary contaminants of
concern affecting the site.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site is no
action with surface water monitoring after severe
storms with hurricane strength winds or any
other act which may disturb sediment. Water
samples will be analyzed for phosphorus, using
a detection limit of 0.01 ug/I, which is 10 percent
of the established toxicity concentrations
approved by EPA, and for metals using EPA
detection limits. There are no present worth or

SITE HISTORY/DESCRIPTION:
The 250-acre USA Letterkenny-PDO site is
within the 19,500-acre active U.S. Army facility
in Chambersburg, Franklin County,
Pennsylvania. Land use in the area is primarily
agricultural, with scattered residences and
military facilities. Shallow ground water at the
head of the site flows toward and into Rocky
Spring and Rocky Spring Lake. Since 1942, the
U.S. Army has used the PDO Area to overhaul,
rebuild, and test wheeled and tracked vehicles;
distribute class III chemicals and petroleum; and
store, maintain, demilitarize, modify, and
demolish ammunition. These past industrial
activities involved the onsite use of solvents, oils,
hydrocarbons, and metals, which were disposed
of in an oil burning pit and several drum storage
revetments. From 1987 until 1989, a number of
EPA investigations documented soil
contamination near the drum storage area and
the oil burning pit; and these areas are thought
to be the primary sources of onsite
contamination. This ROD addresses remediation
of onsite soil as the first operable unit (OU1). A
subsequent ROD will address ground water
contamination as OU2. Because a majority of the
soil contaminants have already moved down into
the clays and silts of the underlying bedrock and
ground water, soil contaminants now pose low
risks for humans at the site, and no remediation
of the soil is necessary. Based on this rationale,
there are no primary contaminants of concern

USA LETTERKENNY SOUTHEAST AREA, PA
August 2,1991
SITE HISTORY/DESCRIPTION:
The USA Letterkenny Southeast Area site is on
a 19,500-acre active U.S. Army facility in
Chambersburg, Franklin County, Pennsylvania.
Land use in the area is primarily agricultural
with scattered residences and military facilities.
Ground water flowing beneath the Southeast site
discharges into two nearby streams. Drinking
water in the 33 residences located within a
3-square-mile radius of the facility has been
affected by ground water contamination from the
site. Since 1942, the U.S. Army has used the
Southeast Area to overhaul, rebuild, and test
wheeled and tracked vehicles; distribute Class III
chemicals and petroleum; and store, maintain,
demilitarize, modify, and demolish ammunition.
These activities past industrial have involved the
use and disposal of TCE, solvents, hydrocarbons,
and metals. As a result of a Federal Interagency
Agreement, EPA conducted several
investigations that identified VOC-contamination
of onsite soil in the K Area associated with the
various burial trenches, pits, and landfills used
for hazardous waste disposal. This ROD
addresses contaminated soil in the Southeast
Area, and is the first operable unit for that area.
Future RODs will address other contaminant
source areas and ground water. The primary
contaminants of concern affecting the soil are
VOCs including TCE and xylenes.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and treating onsite 8,000 cubic yards
of VOC-contaminated soil using low temperature
thermal treatment; controlling vaporized
contaminants using a secondary high-
temperature combustor, or collecting these
vapors by adsorption onto activated carbon;
backfilling the residual ash onsite; disposing of
the residual carbon offsite; artd conducting soil
monitoring. The estimated present worth cost
for this remedial action is $1,539,191. There are
no O&M costs associated with this remedial
action.
PERFORMANCE STANDARDS OR GOALS:
Soil excavation levels will be set at 225 ug/kg for

WHITMOYER LABORATORIES (OPERABLE UNIT 2), PA
December 17,1990
SITE HISTORY/DESCRIPTION:
The 22-acre Whitmoyer Laboratories site is an
abandoned animal pharmaceutical
manufacturing facility in Jackson Township,
Lebanon County, Pennsylvania. Land use in the
area is predominantly agricultural, and there are
wetlands areas adjacent to the site. Part of the
site lies within the 100-year floodplain of the
Tulpehocken Creek-Union Canal, and an
estimated 40 residences in the vicinity of the site
use the underlying aquifer as their drinking
water supply. From 1957 to 1964, Whitmoyer
Laboratories, Inc., produced organic arsenicals
onsite. In 1964, the new site owners, began
storing concentrated wastes in an onsite concrete
vault and, until 1971, conducted onsite pumping
and treatment of ground water and ocean
dumping of wastes. In 1977, sludge from
ground water treatment was placed in onsite
lagoons in the eastern area of the site. Between
1978 and 1982, the site changed ownership twice,
and then in 1985, a RCRA site closure plan was
filed. In 1986, EPA provided bottled water to
residences with contaminated ground water.
Onsite contamination of soil and ground water
has resulted from a combination of poor
housekeeping, poor disposal practices, and
improper storage of hazardous materials. In
1986, arsenic contamination was detected in
nearby residential wells by EPA. When the site
was abandoned in 1987, very little of the RCRA
closure plan had been implemented. From 1988
to 1990, EPA removed the abandoned drums and
laboratory wastes from the site. A 1989 ROD
provided for offsite removal of concentrated
liquids in abandoned tanks and process vessels
as the first operable unit (OU1). This ROD
addresses OU2, which includes remediation of
chemical vault and lagoon wastes, out-dated
products, miscellaneous chemicals and
feedstocks, and contaminated site structures. A
ROD for OU3 will addresses remediation of
contaminated onsite soil and ground water. The
primary contaminants of concern affecting the
debris and sludge are VOCs including benzene,
PCE, toluene, and xylenes; other organics
including phenols; and metals including arsenic
and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and incinerating onsite approximately
3000 cubic yards of high organic content vault
wastes, and approximately 101 cubic yards of
miscellaneous products and feedstocks, followed
by cement/pozzolan-based fixation, and
disposing of the residual ash offsite; treating
approximately 1,500 cubic yards of low organic
content vault wastes using fixation or a similar
fixation process, followed by offsite disposal;
excavating and incinerating onsite approximately
20 buried drums and 50 cubic yards of tank and
process vessel residuals, followed by treating any
residual ash using fixation, and offsite disposal
of residuals; excavating approximately 24,000
cubic yards of arsenic-contaminated lagoon
wastes with levels above 10,000 mg/kg, followed
by fixation of the hazardous lagoons wastes; and
disposing of residuals along with nonhazardous
wastes and other products and feedstocks offsite;
demolishing buildings, associated tanks, vessels,
processing equipment, and debris; incinerating
onsite any combustible debris exhibiting the
RCRA arsenic toxicity characteristic, followed by
offsite disposal; coating and sealing
noncombustible permeable demolition debris
prior to offsite disposal; surface cleaning of
noncombustible impermeable demolition debris,
which exhibit the RCRA arsenic toxicity
characteristic and contaminated onsite structures
before offsite disposal; and offsite disposal or
recycling of untreated unsalvaged demolition
debris. The estimated present worth cost for this
remedial action is $45,800,000. There are no
O&M costs associated with this remedial action
due to selection of offsite disposal for residuals.

SITE HISTORY/DESCRIPTION:
The 22-acre Whitmoyer Laboratories site is an
inactive laboratory facility in Jackson Township,
Lebanon County, Pennsylvania. Land use in the
area is predominantly agricultural with adjacent
wetlands areas. In addition, part of the site lies
within the 100-year floodplain of the
Tolpehocken Creek-Union Canal. An estimated
20 residences in the vicinity of the site use the
underlying aquifer as their drinking water
supply. From 1957 to 1964, Whitmoyer
Laboratories, Inc., produced organic arsenicals
onsite. In 1964, the new owners, Rohm & Haas,
began storing concentrated wastes in a concrete
vault, and until 1971 conducted onsite ground
water pumping and treatment and ocean
dumping of wastes. In 1977, sludge from
ground water treatment was placed in lagoons in
the eastern area of the site. Between 1978 and
1982, the site changed ownership twice, and then
in 1985, a RCRA site closure plan was filed. In
1986, EPA began providing bottled water to
residents with ground water contaminated by
site activities. A public water supply line
extension is currently being designed and will be
constructed as part of a removal action. When
the site was abandoned in 1987, very little of the
RCRA closure plan had been implemented.
From 1988 to 1990, EPA removed approximately
800 abandoned drums and laboratory wastes
offsite. A1989 ROD provided for remediation of
hazardous concentrated liquids, including
laboratory wastes, abandoned at the site as
operable unit 1 (OU1). A December 1990 ROD
provided a remedy for vault and lagoon wastes,
miscellaneous products and feedstocks, tanks,
process vessels, and other onsite structures as
OU2. This ROD addresses contaminated onsite
soil, sediment, and ground water as OU3. The
primary contaminants of concern affecting the
soil, sediment, debris, and ground water are
VOCs including benzene, TCE, and PCE; other
organics including PAHs; and metals including
arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and fixation of approximately 61,000
cubic yards of soil/sediment with contaminant
concentrations above the "principal threat" action
levels using an iron-based or other fixation
process, followed by offsite disposal; using
biological treatment for approximately 5,600
cubic yards of soil/sediment with organic
concentrations above the "principal threat"
organic chemical action levels for the heavily
contaminated soil either prior to or following
fixation, followed by offsite disposal; excavating
and consolidating onsite in the vadose zone
approximately 39,000 cubic yards of
soil/sediment having contaminant concentrations
below the "principal threat" action levels but
above ground water-based unsaturated soil
clean-up targets, followed by capping with
low-permeability materials; placing onsite in the
vadose zone approximately 16,000 cubic yards of
soil/sediment with concentrations below the
ground water-based unsaturated soil action
levels; soil capping any remaining contaminated
surface soil that contains arsenic concentrations
greater than 21 mg/kg and other disturbed
areas, as needed; backfilling, grading, and
revegetating the excavated areas; demolishing
onsite structures, followed by salvaging
non-hazardous debris and offsite disposal of
unsalvaged debris; onsite pumping and
treatment of contaminated ground water using
physical, chemical, and possibly biological
treatment, followed by either onsite discharge to
surface water, reinjection into the aquifer, or
both methods; disposing of any treatment
residuals offsite; conducting long-term ground
water monitoring; and implementing
institutional controls including deed restrictions

for the remaining contaminated areas.
Additionally, this ROD provides a contingency
for ground water if it becomes technically
impracticable to achieve clean-up goals. The
contingent remedy includes pumping from the
perimeter area only to prevent migration of the
contaminant plume. The estimated present
worth cost for this remedial action is $77,300,000,
which includes annual O&M costs of $2,397,600
or $2,477,600 (depending on the ground water
discharge option chosen).
PERFORMANCE STANDARDS OR GOALS:
Soil action levels for saturated and unsaturated
soil and "principal threat" action levels were
developed based on the threat due to inhalation/
ingestion and to ground water using MCLs,
RCRA toxicity characteristic levels (TCLP), and
health-based criteria. The target clean-up goal
for surface soil is arsenic 21 mg/kg. The action
levels for unsaturated soil include benzene
0.009 mg/kg/ PCE 0.051 mg/kg, TCE
0.017 mg/kg, and arsenic 450 mg/kg. This will
reduce the excess cancer risk level associated
with inhalation/ingestion exposure to 10"6. The
action levels for saturated soil include benzene
0.002 mg/kg, PCE 0.012 mg/kg, TCE
0.004 mg/kg, and arsenic 210 ug/kg based on
protection of ground water. Principal threat
action levels include benzene 10 mg/kg, PCE
14 mg/kg, TCE 10 mg/kg, and arsenic
1,000 mg/kg. Ground water clean-up goals are
based on Federal MCLs, proposed MCLs, and a
10"6 excess cancer risk level and reference dose
equal to 1 for noncarcinogens. Chemical-specific
ground water clean-up goals include benzene
0.005 mg/1 (MCL), PCE 0.005 mg/1 (pMCL), TCE
0.005 mg/1 (MCL), and arsenic 0.05 mg/1. A
State ARAR to remediate ground water to
background levels will be waived because of
technical impracticability. If the contingent
remedy is employed, an ARAR to comply with
SDWA MCLs will also be waived because of
technical impracticability.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
contact with remaining contaminated areas.

WILLIAM DICK LAGOONS, PA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 4.4-acre William Dick Lagoons site is a
chemical wastewater disposal site in West Cain
Township, Chester County, Pennsylvania. Land
use in the area is predominantly residential and
agricultural, with adjacent woodlands. An
estimated 30 residences located within 1,000 feet
of the site use private wells for their drinking
water supply. Two other Superfund sites are
near the site: the Blosenski Landfill located 1.7
miles southeast; and the Welsh Landfill, 5 miles
to the northwest. Originally, the site consisted of
three unlined earthern lagoons or ponds
covering 2.2 acres and an associated borrow area.
From the WSffs to 1970, Mr. William Dick used
the lagoons to dispose of wastewater left from
cleaning the interiors of chemical and petroleum
tank trailers owned primarily by Chemical
Leaman Tank Lines (CLTL), and residual
chemical products. In 1970, the State ordered the
lagoons closed after 37 wild geese descended
into the lagoons, and were coated with waste.
Later in 1970, vandalism caused the release of an
estimated 300,000 gallons of wastewater into
Birch Run, a tributary of the West Branch of
Brandywine Creek. As a result of this discharge,
more than 2,600 fish died, and water supplies
that used Brandywine Creek as a water source
were closed. In 1971, William Dick and CLTL
began lagoon closure as part of a State
agreement. Activities during 1971 included the
addition of alum to the wastewater, spray
irrigation of the treated wastewater into the
woods, and covering and revegetating lagoons
with soil. During 1985, site studies identified
numerous organic compounds in soil samples,
two spring-fed water supplies, and five wells. In
1988, EPA required CLTL to fence around the
site, conduct yearly monitoring of residential
wells, and install point-of-entry treatment
systems for selected private wells. In 1990 and
1991, sampling revealed TCE and other
contaminants in 30 to 40 private wells. As a
result, CLTL installed point-of-entry carbon
filtration units in 12 of the 30 to 40 homes where
contamination in well water exceeded MCLs.
This ROD provides an interim remedy and
addresses contaminated residential water as
operable unit 1 (OU1) and ground water as OU2.
A future ROD will address source control and
will provide a remedy for the cleanup of
contaminated soil. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, PCE, and TCE; other organics
including phenol; and metals,
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
providing an alternate water supply to affected
residences by extending the City of Coatesville
Authority's water line; installing a water storage
tank near the site to provide storage and
pressure feed for the water line connections;
monitoring nearby springs; collecting
hydrogeologic data; conducting initial pumping
and onsite treatment of the contaminated ground
water plume using treatment components that
will be selected during interim remedial design,
which are expected to include chemical
precipitation and one of more of the following:
granular activated carbon, chemical oxidation,
and air stripping, with possible emission
controls; discharging the treated water onsite to
surface water; installing monitoring and recovery
wells to further characterize the entire plume;
and implementing institutional controls
including ground water use restrictions. The
estimated present worth cost for this remedial
action ranges from $5,991,000 to $7,028,000,
which includes an annual O&M cost of $305,000
to $330,000 for years 0-5, and $21,000 to 46,000
for years 6-30.

ABERDEEN PESTICIDE DUMPS (AMENDMENT), NC
September 30,1991
SITE HISTORY/DESCRIPTION.
The Aberdeen Pesticide Dumps site consists of a
plant area and four disposal areas in Aberdeen,
Moore County, North Carolina. The five areas
are Farm Chemicals,. Twin Sites, Fairway Six,
Mclver Dump, and Route 211. Surrounding land
use is primarily residential with some light
industry. Ground water is the main source of
drinking water for local residents. From the
1930's until 1987, chemical companies
neighboring the site blended or formulated
pesticides at the formulation plant located on the
Farm Chemicals area. During operations at the
plant, substantial quantities of pesticide wastes
were disposed of or spilled onsite. After
investigations by EPA's Emergency Response
Section in 1985 and 1986, several removal actions
were conducted including removing surface
contaminants, drums, and soil in several areas.
One removal action, conducted in 1988, resulted
in the excavation of 22,000 cubic yards of
contaminated soil, which was subsequently
stockpiled in the Fairway Six area. This
stockpile was designated as operable unit 2
(OU2). A 1989 ROD documented the selected
remedy for OU2, which included onsite
incineration of the stockpiled material and onsite
disposal of the residual ash. OU2 has
subsequently been redesignated as OU4 and
implementation of the selected remedy
postponed pending a selected remedy for OU1.
A fourth removal action in 1989 resulted in the
excavation and stockpiling of 3,200 cubic yards
of pesticide-laden soil. In 1986, pesticides were
detected in drinking water from four municipal
wells and three private wells. A 1989 EPA
investigation of the remaining areas of the site,
designated as OU1, revealed a total of 98,733
cubic yards of contaminated soil, in addition to
that stockpiled in the Fairway Six and Maclver
Dump Areas, that require remediation. This
ROD concurrently addresses surface and
subsurface soil contamination addressed in OU1
and the former OU2, and includes a change of
treatment technology for the former OU2 from
incineration to thermal desorption. The purpose
of this response action is to prevent current or
future exposure to the contaminated soil and to
reduce further contaminant migration into the
ground water. The primary contaminants of
concern affecting the soil and debris are organics
including pesticides; metals including arsenic,
chromium, and lead; and asbestos, an inorganic.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes conducting a treatability study using
thermal desorption; excavating and treating a
total of 123,933 cubic yards of soil from all five
areas including previously excavated soil from
the Fairway Six and Mclver Dump areas using
an onsite thermal desorption process that
includes an activated carbon adsorption to treat
off-gases, followed by offsite incineration of
residual organics or disposal in another
appropriate manner; disposing of the
non-hazardous treated soil onsite in the original
excavated areas; onsite solidification and
disposal of any residue that remains hazardous
after thermal treatment; removing asbestos and
building demolition at the Farm Chemicals area;
and sampling and analyses of site soil, as
necessary, to confirm clean-up status. A
contingent remedy will be implemented if the
results of the treatability study conclude that
thermal desorption is ineffective or cost
prohibitive. The contingent remedy will include
all items detailed under the selected remedy
except that incineration would be used as the
treatment technology instead of thermal
desorption. The estimated present worth cost for
this remedial action is $29,115,000, which
includes an annual O&M cost of $115,000.

ARLINGTON BLENDING & PACKAGING, TN
June 28,1991
SITE HISTORY/DESCRIPTION:
The 2.3-acre Arlington Blending & Packaging site
is an abandoned pesticide and herbicide
blending and packaging facility in Arlington,
Shelby County, Tennessee. Land use in the area
is predominantly residential, agricultural, and
light commercial. Site operations have
contaminated two units of the underlying
aquifer, which are not used as drinking water
sources. From 1971 to 1978, the Arlington
Blending & Packaging Company operated onsite
to properly formulate and package various
pesticide, herbicide, and other chemical
formulations. During site operations, spills and
leaks of chemicals occurred onsite, which
resulted in compounds soaking into soil and
process building flooring, and migrating offsite
via surface run-off. Process water containing
hazardous contaminants also was discharged to
onsite ditches, contaminating adjacent properties
including a residential area, nearby ditches, and
other surface water bodies. In addition,
numerous barrels and other containers were left
onsite. Site investigations revealed onsite and
offsite contamination of soil and ground water.
In 1983, EPA initiated a removal action, and
excavated and removed 1,920 cubic yards of
contaminated soil with chlordane levels in excess
of 50 mg/kg and 112 drums containing chemical
wastes. In 1990, as a result of the RI data, EPA
conducted another removal action, and
excavated and temporarily stored onsite 70 cubic
yards of contaminated soil from the adjacent
residential property. This ROD addresses final
remediation of primarily pesticide-contaminated
soil and ground water. The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including benzene;
other organics including pesticides; and metals
including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating 24,000 cubic yards of contaminated
soil and decontaminating the soil onsite using
ex-situ thermal desorption; backfilling excavated
areas with treated soil; dechlorinating the
resulting condensed organic liquid from the
thermal desorption process, followed by offsite
disposal of the residual concentrated organic
liquid; treating and disposal of spent carbon or
sludge offsite; temporarily storing residuals
onsite, if needed, prior to treatment to
treatability levels; and offsite disposal; treating
soil containing levels of arsenic and/or other
trace metals above action levels onsite using
solidification, followed by offsite disposal;
decontaminating and demolishing onsite
buildings, followed by offsite disposal; pumping
and onsite treatment of contaminated ground
water using activated carbon, followed by onsite
discharge of the treated effluent to surface water
or offsite to a POTW; regenerating spent carbon
granules offsite; monitoring ground water; and
providing for a contingency remedy that
involves treating soil onsite using thermal
destruction instead of thermal desorption. The
estimated present worth cost for this remedial
action is $12,170,167, which includes a total
present worth O&M cost of $1,605,256 for 30
years.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up levels are based on protection of
ground water and reduction of risk through
long-term dermal contact and oral ingestion, and
include arsenic 25,000 ug/kg, which also takes
into account background levels.
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include benzene
5 ug/1.

CAROLINA TRANSFORMER, NC
August 29,1991
SITE HISTORY/DESCRIPTION:
The 4.8-acre Carolina Transformer site is a
former electrical transformer rebuilding and
repair facility in Fayetteville, Cumberland
County, North Carolina. Land use in the area is
predominantly agricultural and residential, with
a wooded/swamp-like area adjacent to the site.
The site may overlie as many as three aquifers,
of which only the shallow confined aquifer has
been found to be contaminated. From 1967 to
1982, Carolina Transformer Company rebuilt and
repaired electrical transformers onsite. During
site operations, PCB fluids were drained from
transformers and improperly stored and
managed. From 1978 to 1982, a number of EPA
and State investigations identified PCB-
contaminated soil and ground water. In 1982,
the State determined that run-off from the site
violated surface water quality standards for
PCBs. In 1984, EPA began clean-up operations
at the site, and removed and disposed of 975
tons of contaminated soil offsite in a
RCRA-permitted landfill. This ROD addresses
final remediation of contaminated soil, sediment,
debris, and ground water. The primary
contaminants of concern affecting the soil,
sediment, debris, and ground water are VOCs
including benzene and toluene; other organics
including dioxin and PCBs; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and treating onsite soil and sediment
contaminated with PCBs in excess of 1 mg/kg
using a solvent extraction process to separate the
organic contaminants and polynuclear aromatic
compounds from the soil and sediment and to
lower the solubility and mobility of the inorganic
contaminants; backfilling the excavated area with
treated soil; solidifying soil and sediment that
does not meet the RCRA Toxicity Characteristic
Rule; demolishing 970 cubic yards of roof and
wall material from three onsite buildings and
transporting the debris to an offsite landfill;
treating any remaining structural material
contaminated with PCBs in excess of
10 ug/100 cm2 using a solvent washing system;
transporting 180 cubic yards of debris and solid
waste to an offsite landfill for disposal and/or
treatment; pumping and onsite treatment of
contaminated ground water using precipitation
to remove metals and activated carbon
adsorption to remove VOCs, followed by onsite
discharge to surface water or offsite discharge to
a POTW; dewatering sludge generated from the
ground water precipitation process, followed by
offsite disposal; conducting ground water
monitoring; and establishing a contingency
remedy for ground water remediation, which
includes ground water engineering controls,
ARAR waivers, institutional controls, continued
monitoring of specified wells, and periodic
reevaluation of remedial technologies if it is
determined that certain portions of the aquifer
cannot be restored to their beneficial uses. The
estimated present worth cost for this remedial
action is $10,474,500, with an O&M cost of
$78,100 for years 0-1 and $17,400 for years 2-30.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil/sediment clean-up goals
are based on carcinogenic risk and EPA
guidelines, and include dioxin 1.2 x 10"4
(carcinogenic risk) and total PCB 1 mg/kg (EPA
guidelines). Chemical-specific ground water
clean-up goals are based on SDWA MCLGs, EPA
guidance, and State standards, and include
benzene 1 ug/1 (State), chromium 50 ug/1
(MCLG), lead 15 ug/1 (EPA guidance), PCB-1260
0.1 ug/1 (State), and toluene 1,000 ug/1 (State).

from the municipal system. From 1979 to 1982,
unpermitted waste oil recycling was conducted
at the facility using a large boiler to separate the
waste oil from other wastes. Site features
resulting from these activities include drum
storage areas, 12 unlined or partially lined
oil/water waste storage lagoons, buildings,
2 truck tankers, and 14 tanks. In 1980, State
inspectors observed that several of the lagoons
were overflowing with metal-contaminated oil
and sludge contaminating the ground. They also
discovered 175 deteriorating 55-gallon drums
containing various chemicals including VOCs
and other organics. In a 1981 EPA RCRA
compliance inspection of the Macon site,
10 violations of RCRA regulations were cited.
Subsequently, a court order required the PRPs to
initiate clean-up activities at Macon in 1982,
which led to identification of 2,100 drums,
10 tanks, and 11 lagoons of concern. Private
funds were used to remove 300 drums and the
contents of one lagoon, as well as to install two
monitoring wells, before being depleted. EPA
continued site activities in 1983 by removing
3,123 tons of waste and 137,000 gallons of oil. In
1984, EPA conducted similar removal activities at
the Dockery site, and removed 709 tons of waste.
After removal activites for both properties had
been completed in 1984, all but one lagoon,
referred to as Lagoon 10, had been excavated
and backfilled. Because of the size of Lagoon 10,
EPA decided to backfill and cap the lagoon
without excavating the contents. Recent
investigations, however, revealed that site soil
and ground water still pose a threat, particularly
downgradient of source areas such as lagoon
areas. This ROD addresses soil, vessels
containing hazardous materials, and ground
water, which is the principal threat at the site,
and is a final remedy. The primary
contaminants of concern affecting the soil,
sludge, debris, and ground water are VOCs
including PCE, TCE, toluene, and xylenes; other
organics including PAHs; and metals including
arsenic and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating VOC-contaminated soil around the
Lagoon 7 area using in-situ vapor extraction,
with a carbon adsorption system to remove
off-gas organic contaminants; excavating and
treating PAH-contaminated soil from Lagoon 10
in an onsite, biological waste treatment cell
equipped with a carbon adsorption system to
control emissions, followed by returning the
treated soil to Lagoon 10 and covering with a
low permeability cap; emptying and dismantling
all vessels and demolishing buildings as
necessary, and offsite disposal or recycling of
hazardous and non-hazardous wastes; further
sampling of soil, sediment, and surface water;
pumping and treatment of ground water using
air stripping and coagulation/filtration, followed
by discharging treated water to surface water if
NPDES standards are met or to an infiltration
gallery if standards are not met; and monitoring
ground water. The estimated present worth cost
for this remedial action is $8,700,000, which
includes an estimated present worth O&M cost
of $5,400,000 for 30 years.

CIBA-GEIGY, AL
September 30,1991
SITE HISTORY/DESCRIPTION:
The 1,500-acre Ciba-Geigy site is an active
chemical manufacturer in an industrial area in
Mclntosh, Washington County, Alabama. A
wetlands area borders the site property, and part
of the site lies within the floodplain of the
Tombigbee River. From 1952 to present,
Ciba-Geigy, formerly Geigy Chemical
Corporation, has produced various chemicals
including DDT, laundry products, herbicides,
insecticides, agricultural chelating agents,
sequestering agents, plastic resins and additives,
antioxidants, and specialty chemicals. In 1982
during an investigation of an adjacent chemical
company, EPA identified onsite contamination in
a drinking water well on the Ciba-Geigy
property. In 1985, EPA issued a RCRA permit
that included a corrective action plan requiring
Ciba-Geigy to remove and treat ground water
and surface water contamination at the site.
EPA performed further investigations to
determine the extent of contamination, and
revealed 11 areas of waste management and
potential contamination. These areas contain a
variety of waste, debris, and pesticide
by-products and residues. In 1987, as part of the
corrective action plan requirements, Ciba-Geigy
installed an additional wastewater treatment
system and ground water monitoring wells. A
1989 ROD provided for treatment of the
contaminated shallow alluvial aquifer by using
the onsite wastewater treatment plant as
operable unit 1 (OU1). This ROD addresses
highly contaminated soil and sludge at 10 of the
11 former waste management areas as OU2.
Future RODs will address contamination within
the floodplain including the lower portions of an
onsite drainage ditch and areas in the Tombigbee
River in proximity of the site (OU3), and
contamination in the remaining untreated former
waste management area and the upland portions
of the drainage ditch (OU4). The primary
contaminants of concern affecting the soil,
sludge, and debris are VOCs including benzene
and toluene; other organics including PCBs and
pesticides (e.g., DDT); and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for the site includes
excavating contaminated soil and sludge from
within the 10 disposal areas until established
clean-up levels are reached or to a maximum
depth of 20 feet; treating 65,000 cubic yards of
highly-contaminated soil and sludge onsite using
thermal treatment; evaluating the possibility of
pretreatment via solvent extraction, low
temperature thermal treatment, or critical fluid
injection and implementing this process, if
advantageous; treating 62,300 cubic yards of
moderately contaminated soil and sludge using
stabilization/solidification or a proven
innovative technology; obtaining a treatability
variance to dispose of the treated soil and
residual ash in an onsite landvault; treating deep
soil areas, where risk-based levels have not been
achieved during excavation to the depth of 20
feet, using in-situ soil flushing combined with
isolation walls, extraction wells alone, or possibly
extraction wells in combination with in-situ
vacuum extraction or in-situ bioremediation,
whichever is found to most effective; backfilling
and revegetating the excavated areas; operating
and maintaining the landvaults for a minimum
of 30 years; monitoring ground water; and
implementing institutional controls where
necessary including land and ground water use
restrictions. The present worth costs for this
remedial action range from $94,000,000, if
solidification of low level contaminated soil is
effective, to $120,250,000, if incineration of all
contaminated material is required. O&M costs

GOLDEN STRIP SEPTIC TANK, SC
September 12,1991
SITE HISTORY/DESCRIPTION:
The 55-acre Golden Strip Septic Tank (GSST) site
is an inactive waste hauling and disposal facility
in Simpsonville, Greenville County, South
Carolina. Land use in the area is predominantly
residential. The estimated 638 residents who
reside within a quarter-mile of the site use public
water as their drinking water supply. From 1960
to 1975, GSST used the site to dispose of
industrial and septic wastes in five unlined
lagoons. In 1975, GSST applied for an industrial
solid waste permit to dispose of liquid wastes,
but the State denied the permit because the
proposed disposal method was unacceptable.
Subsequently, in 1978, GSST discontinued waste
collection, hauling, and disposal, and filled in
three of the five lagoons by pushing in
surrounding berms. State investigations of the
site began in 1972 and included a site survey of
lagoons and the surrounding area. The State
continued its monitoring after the lagoons were
filled and graded in 1978 and the results of the
monitoring led to additional investigations by
EPA in 1984 and 1986 and an RI and
supplemental RI from 1989 to 1990 and 1990 to
1991, respectively. EPA identified metal
contamination in lagoon soil and sludge, and
limited contamination of ground water. In
addition, 27 abandoned drums that contained
low levels of contaminants were found on the
east side of the site. Six of the drums have been
placed in overpack drums and stored in an
onsite temporary drum storage area. This ROD
addresses remediation of contaminated soil, as
well as sludge and surface water from the
lagoons, as a final remedy. Ground water
contamination is expected to naturally attenuate
within 2 to 5 years after source remediation
occurs. The primary contaminants of concern
affecting the soil, sludge, and surface water are
VOCs including benzene, PCE, toluene, and
xylenes; other organics; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and treating onsite approximately
22,400 cubic yards of soil and 4,200 cubic yards
of sludge using solidification/fixation; backfilling
the treated residuals, covering the area with
clean soil, and revegetating the site; discharging
off site 1.9 million gallons of impounded surface
water from Lagoons 1 and 4 to a POTW;
disposing of drummed liquids, along with other
surface water; establishing Alternate
Concentration Limits (ACLs) for the MCLs that
are periodically exceeded in the ground water to
ensure that source control measures have a
positive effect on ground water; conducting
long-term ground water and surface water
monitoring; investigating further the
contamination from the abandoned onsite drums;
and implementing institutional controls to
control site development. The estimated present
worth cost for this remedial action is $4,529,000,
which includes an annual O&M cost of $991,500.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based
on health-based criteria and include arsenic
18 mg/kg, cadmium 65 mg/kg, chromium 580
mg/kg, lead 500 mg/kg, PCE 56 mg/kg, toluene
12,000 mg/kg, and xylenes 120,000 mg/kg.
Ground water ACLs will be established based on
the arithmetic mean of the first four samples of
each constituent for that well. For means that do
not exceed the MCLs, the MCL will be the
applicable standard against which ground water
monitoring results will be compared.

HERCULES 009 LANDFILL, GA
June 27,1991
SITE HISTORY/DESCRIPTION:
The 16.5-acre Hercules 009 Landfill site is in
Brunswick, Glynn County, Georgia. Land use in
the area is predominantly commercial and
residential. Onsite features in the northern
7 acres of the site are a landfill area with
6 disposal cells containing approximately 33,000
cubic yards of 1 percent toxaphene sludge, a
drainage ditch, and a drainage culvert. Most of
the estimated 1,400 residents within 3 miles of
the site are connected to a public water supply,
except for 6 homes and a church that use private
wells as their drinking water supply. From 1948
to 1980, Hercules, Inc., manufactured the
agricultural pesticide toxaphene. Waste from the
manufacturing process was accumulated by
storing toxaphene-contaminated wastewater in
the offsite settling ponds. In 1975, the State
permitted the site to accept and dispose of
pesticide waste including toxaphene, in the 009
landfill site. Also disposed of in the landfill area
were empty toxaphene product drums, process
sludges, glass, rubble, and trash. In 1979, a State
inspection detected elevated levels of toxaphene
in sediment and surface water in the adjacent
drainage ditch, and in 1980, the State revoked
Hercules' operating permit. In 1983, the State
required Hercules to install a ground water
monitoring system to assess site contamination.
In 1984, because toxaphene was found in a
deep/shallow well cluster in the aquifer beneath
the site, additional ground water monitoring
wells were installed. Hercules closed, covered,
and seeded all landfill cells in accordance with
State solid waste permits. This ROD addresses
operable unit 2 (OU2), the contaminated ground
water, as an interim action. Future RODs will
fully address the principal threat posed by the
site. The primary contaminants of concern
affecting the ground water are organics
including pesticides.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes extending municipal water lines
and connecting all residences with private wells
and the church to the municipal water supply;
and implementing institutional controls,
including ground water use restrictions. The
estimated capital cost for this remedial action is
$106,000. There are no O&M costs associated
with this remedial action.

INTERSTATE LEAD (ILCO), AL
September 30,1991
SITE HISTORY/DESCRIPTION:
The Interstate Lead (ILCO) site consists of seven
subsites located in and around the City of Leeds,
Jefferson County, Alabama. The site includes an
8.5-acre active lead smelting facility and its
parking lot, a service station; a manufacturing
company; a church parking lot; a l.4-acre
residential property; a municipal landfill; and a
restaurant. Land use in the area is mixed
industrial and residential. Parts of the ILCO site
overlie the Fort Payne Chert and Ordovician
Undifferentiated aquifers, both of which are
sources of drinking water for the City of Leeds.
Since 1970, ILCO has manufactured refined lead
alloys through the smelting and refining of
lead-bearing scrap metals including lead-acid
automobile batteries. The resultant furnace slag
has been disposed of at the seven subsites along
with battery casings and wastewater treatment
sludge. From 1973 to 1984, ILCO stored furnace
slag, battery chips, and wastewater treatment
sludge in piles at the main facility and also used
these wastes as fill material at the other site
areas. Additionally, some waste was disposed of
at the municipal landfill. State investigations in
1983 and 1984, and a number of subsequent EPA
investigations, identified metal contamination in
onsite soil, sediment, ground water, surface
water, and air. In 1984, EPA conducted an
emergency removal action at the church subsite,
and removed and disposed of approximately
5,000 cubic yards of waste material and soil
offsite. This ROD provides a final remedy for
soil contamination at all of the subsites except
the main facility portion of subsite #1, and
ground water contamination at four of the
subsites as operable unit 1. Future RODs will
address sediment, ground water, and surface
water contamination at the main facility. The
primary contaminants of concern affecting the
soil, sediment, debris, and ground water are
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected source control remedial action for
the ILCO parking lot and the restaurant subsites
includes excavating soil and sediment with lead
concentrations exceeding 300 mg/kg and 50
mg/kg, respectively; controlling dust with water
spray during excavation and removal;
dewatering the sediment; treating the
contaminated material onsite using solidification
and stabilization; replacing the treated soil into
the excavated areas in compliance with RCRA
requirements, and capping the areas; removing
battery casings and other debris with
solidification of battery casing material, and
onsite disposal of solidified material and offsite
disposal of other debris; and conducting air
monitoring. The selected source control
remedial action for the service station, the
manufacturing company, the residential
property, and church subsites includes
excavating and treating soil using solidification
and stabilization at a centrally located treatment
area in the parking lot subsite; disposing of
treated material at the ILCO parking lot; filling
and revegetation of excavated areas with clean
soil, or disposing of treated materials in the
original excavated areas with implementation of
institutional controls including deed restrictions;
removal of sediment exceeding 50 mg/kg lead,
dewatering, and treating the sediment along
with the soil; and air monitoring. The selected
source control remedial action for the municipal
landfill includes constructing a multi-layer cap
over soil contaminated with lead concentrations
exceeding 300 mg/kg; implementing institutional
controls including land use restrictions, and
access restrictions; and ground water monitoring.
The selected ground water remedial action for

MALLORY CAPACITOR, TN
August 29,1991
SITE HISTORY/DESCRIPTION:
The 8.6-acre Mallory Capacitor site is a former
electrical capacitor manufacturing facility in
Waynesboro, Wayne County, Tennessee. Land
use in the area is mixed residential, commercial,
and industrial, with the Green River bordering
the site to the east. There are 54 private wells
located within a 1-mile radius of the site that
draw on the Fort Payne Formation aquifer for
ground water. The Mallory Capacitor Company
was operated from 1969 to 1979 by Duracell, and
from 1979 to 1984 by Emhart Industries to
manufacture electrical capacitors onsite using
TCE as part of the process. Process liquid
wastes were stored in underground storage
tanks onsite. From 1976 to 1980, clean-up actions
were implemented by Emhart to remove
PCB-contaminated materials from process
equipment within the manufacturing facility.
These actions also included removing the
underground storage tank adjacent to the plant
and associated surrounding PCB-contaminated
soil. In 1984, routine TCE still bottom testing
revealed PCB-containing still bottoms. The
facility was subsequently shut down because of
unsafe working conditions. Subsequent studies
revealed significant levels of PCBs on portions of
the plant structure, in process equipment, and in
soil; and elevated VOC levels also were
identified in ground water. This ROD addresses
contaminated ground water as a final remedy.
The primary contaminants of concern affecting
the ground water are VOCs including 1,2-DCE
and TCE; and other organics including PCBs.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
ground water pumping and onsite treatment
using air stripping; removing precipitates using
filtration and carbon adsorption, followed by
onsite discharge to the Green River or offsite
discharge to a POTW; monitoring ground water;
conducting additional investigations to assess the
extent of offsite ground water contamination and
the impact to surface waters; and implementing
institutional controls including deed and ground
water use restrictions. If it is determined that,
based on site conditions, PCBs are resistant to
removal by pumping and that ground water
cannot be restored to beneficial use for any or all
of the contaminants, all of the following
long-term management measures may be
implemented: employing engineering controls as
containment measures; invoking
chemical-specific ARAR waivers for aquifer
cleanup based on technical impracticability;
implementing institutional controls to restrict
access to the aquifer; reevaluating remedial
technologies for ground water remediation; and
continued monitoring of specified wells. The
estimated present worth cost for this remedial
action is $3,005,000.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include PCBs
0.5 ug/1, TCE 5 mg/1, and cis- and trans-l,2-DCE
70 ug and 100 ug/1, respectively.

MAXEY FLATS NUCLEAR DISPOSAL, KY
September 30,1991
SITE HISTORY/DESCRIPTION:
The 280-acre Maxey Rats Nuclear Disposal site
is an inactive low-level radioactive waste
disposal facility in Fleming County, Kentucky.
Land use in the area is predominantly
agricultural and residential, with mixed
woodlands surrounding the site. The estimated
663 people who reside within 2.5 miles of the
site use the public water supply for drinking
purposes. From 1962 to 1977, Nuclear
Engineering Company, Inc. {NECO), operated a
solid by-product source, and special nuclear
material disposal facility under a license with the
State. During this time, NECO disposed of
approximately 4,750,000 cubic feet of low-level
radioactive waste in an approximately 45-acre
area, designated as the "Restricted Area". The
majority of the waste was disposed of in unlined
trenches, but concrete capped "hot wells"
consisting of coated steel pipe, tile, or concrete
also were used for disposal of small-volume
wastes with high-specific activity. The wastes
were deposited in 52 disposal trenches within 27
acres of the Restricted Area in both solid and
solidified-liquid form and were both
containerized and deposited loosely. Several
State investigations in the 1970*5 revealed that
leachate contaminated with tritium and other
radioactive substances was migrating from the
disposal trenches to unrestricted areas. In 1977,
the State ordered NECO to cease the receipt and
burial of radioactive waste. From 1973 to 1986,
an evaporator was operated onsite as a means of
managing the large volume of water infiltrating
the disposal trenches as well as wastewater
generated by onsite activities. The evaporator
processed more than 6,000,000 gallons of liquids,
leaving behind evaporatory concentrates that
were stored in onsite above-ground tanks, and
eventually disposed of in an onsite trench. In
1979, the State initiated stabilization and
maintenance activities including installing a
temporary PVC cover over the disposal trenches
to minimize rainfall infiltration. In 1988, EPA
conducted a two-phase removal action to handle
the threat posed by 11 onsite 20,000-gallon tanks
of questionable structural integrity located in a
tank farm building. Phase I consisted of
installing a heater in the tank farm building to
prevent the freezing and rupturing of tank
valves and fittings. Phase II consisted of
solidifying approximately 286,000 gallons of
radioactive liquids stored in the 11 tanks and
water on the floor of the tank farm building.
The solidified blocks will be disposed of onsite
in a newly constructed trench. This ROD
addresses final remediation of soil, debris, and
associated leachate. The primary contaminants
of concern affecting the soil and debris are VOCs
including benzene, TCE, and toluene; metals
including arsenic and lead; and radioactive
materials.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
extracting, solidifying, and disposing onsite of
approximately 3,000,000 gallons of trench
leachate; demolishing and disposing of site
structures onsite; excavating additional disposal
trenches for disposal of site debris and solidified
leachate; installing an approximately 50-acre

MEDLEY FARMS, SC
May 29,1991
SITE HISTORY/DESCRIPTION:
The 7-acre Medley Farms site is a former waste
disposal area located on a private farm used as
pasture 6 miles south of Gaffney, Cherokee
County, South Carolina. Land use in the area is
predominantly agricultural and light residential,
and six private wells are within a 1-mile radius
of the site. The site overlies a shallow saprolitic
and a deeper bedrock aquifer. All residents in
the near vicinity of the site are connected to the
public water distribution system. From 1973 to
1976, the site was used for disposal of drummed
and other waste materials. In 1983, the State
identified approximately 2,000 deteriorating
55-gallon drums and numerous plastic containers
scattered throughout the site. Other observations
included a chemical odor in the air, several
excavation pits containing discolored water and
drums, and stressed vegetation. Several State
and EPA studies identified VOCs and other
organics in onsite soil. In 1983, EPA removed
5,383 fifty-five-gallon and fifteen-gallon
containers; disposed of empty drums offsite;
bulked 24,000 gallons of liquid wastes, with
offsite incineration of the wastes; crushed and
disposed of the empty drums offsite; excavated
and disposed of 2,132 cubic yards of
contaminated soil offsite; drained 70,000 gallons
of water from six small lagoons, followed by
treatment using a pressurized sand/gravel/
activated carbon filtration system to remove
organic contaminants; and backfilled the lagoons
with clean soil. Following this removal action,
EPA conducted a geological study to determine
the potential for ground water contamination.
Subsequent EPA studies identified VOCs in both
soil and ground water. This ROD addresses soil
and ground water contamination as a final
remedy. The primary contaminants of concern
affecting the soil and ground water are VOCs
including benzene, PCE, and TCE; and other
organics including pesticides and PCBs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating contaminated soil onsite using in-situ
vapor extraction, and controlling air emissions
using carbon adsorption; regenerating or
disposing of the spent carbon; pumping and
treatment of contaminated ground water using
precipitation, flocculation, ion exchange, or some
other method of metal removal if necessary,
followed by air stripping; discharging the treated
water onsite to surface water; and monitoring
ground water, surface water, soil, and sediment.
If the ground water treatment system cannot
meet the specified remediation goals,
contingency measures and goals will be
implemented including engineering controls or
institutional controls, invoking chemical-specific
ARAR waivers, or reevaluating remedial
technologies for ground water restoration. The
estimated present worth cost for this remedial
action is $2,404,000, which includes an annual
O&M cost of $1,451,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals were
derived from calculations based on leachate
modeling, and include PCE 1,600 ug/kg and
TCE 500 ug/kg. Chemical-specific ground water
clean-up goals are based on SDWA MCLs and
proposed MCLs, and include benzene 5 ug/1
(MCL), PCE 5 ug/1 (MCL), and TCE 5 ug/1
(MCL).
INSTITUTIONAL CONTROLS:
Ground water use restrictions may be
implemented to restrict access to those portions
of the aquifer which may remain above
health-based levels.

SITE HISTORY/DESCRIPTION:
The 75-acre Monsanto site is a former industrial
plant located 3 miles southeast of Augusta,
Georgia. Land use in the area is predominantly
industrial, with a wetland area located
approximately 4,570 feet from the site. In
addition, the site is approximately 3 miles from
the Savannah River, an important source of
water for the Augusta area. The plant began
operations in 1962. From 1966 to 1974,
approximately 1,500 pounds of arsenic were
placed in two onsite landfills. The landfills were
covered with soil, crowned with gravel, seeded
with grass, and closed in 1971 and 1977,
respectively. Ground water investigations
conducted in 1979 and 1980 by Monsanto
identified arsenic in the surficial aquifer in
excess of the Federal MCL. In 1983, Monsanto,
through a State action, excavated the materials in
the landfills and disposed of them offsite. Soil
samples collected from the bottom of the
excavated area did not exceed the EP toxicity
standard for arsenic. This final ROD addresses
ground water contamination. The primary
contaminant of concern affecting the ground
water is arsenic, a metal.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
monitoring ground water to evaluate compliance
with Ground Water Protection Achievement
Levels (GPALs); pumping and discharging
ground water to an offsite POTW, in the event
that non-compliance with GPALs occurs;
monitoring ground water for 2 years following
EPA's acceptance that the MCL has been
attained. The estimated present worth cost for
this remedial action is $600,000.

OAK RIDGE RESERVATION (USDOE)(OPERABLE UNIT 2), TN
June 28,1991
SITE HISTORY/DESCRIPTION:
The Oak Ridge Reservation (ORR) (USDOE) site
is an inactive uranium recovery landfill in Oak
Ridge, Anderson County, Tennessee. The United
Nuclear Corporation (UNO disposal site, which
comprises operable unit 2 (OU2), is one of
several hundred waste disposal sites or areas of
contamination at the ORR site requiring
Superfund remedial action. From 1982 to 1984,
the 1.3-acre disposal site received 11,000
55-gallon drums of cement-fixed sludge, 18,000
drums of contaminated soil, and 288 wooden
boxes of contaminated building and process
equipment demolition debris from the
decommissioned UNC uranium recovery facility
in Wood River Junction, Rhode Island. The
wastes were placed in 5- to 50-foot deep pits and
covered with polyvinyl chloride sheeting.
Although some drums and boxes have
deteriorated, rusted, or split open, investigations
show that migration of contaminants to soil and
ground water has not yet occurred. This ROD
addresses the drummed soil, sludge, and debris
to prevent future ground water contamination.
Subsequent RODs are planned to fully address
the principal threats posed by the ORR site. The
primary contaminants of concern affecting the
soil, sludge, and debris are nitrite, an inorganic;
and strontium-90, a radioactive material.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
clearing and grubbing sparse vegetation; placing
a multi-layer cover over the drums, soil, sludge,
and debris; revegetating the area and backfilling
over the UNC waste with additional soil; and
monitoring ground water. The estimated
present worth cost for this remedial action is
$1,467,500, which includes an annual O&M cost
of $93,600 for year 0-1 and $69,800 for years 2-30.
PERFORMANCE STANDARDS OR GOALS:
The selected remedy will prevent future
contamination of ground water from landfill
wastes. Accordingly, the remedy will meet the
SDWA MCL for nitrate 10 mg/1 at downgradient
wells and meet a 10"6 risk level for strontium-90.

OAK RIDGE RESERVATION (USDOE)(OPERABLE UNIT 3), TN
September 19,1991
SITE HISTORY/DESCRIPTION:
The Oak Ridge Reservation (ORR) (USDOE)
(Operable Unit 3) site is an active nuclear
weapons component manufacturing facility
located in Oak Ridge, Anderson County,
Tennessee. The Y-12 plant, which is addressed
as operable unit 3, is one of several hundred
waste disposal sites or areas of contamination at
the ORR site requiring Superfund remedial
action. The site occupies the upper reaches of
East Fork Poplar Creek (EFPC) in Bear Creek
Valley. From 1940 to the present, the Y-12 plant
has been used to produce nuclear weapons
components. From 1955 to 1963, mercury was
used in a column-exchange process to separate
lithium isotopes. Mercury spills from this
process resulted in mercury and
mercury-contaminated sediment being pumped
from the basements of buildings into three
concrete sedimentation tanks connected to storm
sewers, which discharge to EFPC. Testing of the
three concrete tanks showed that the tank
sediment contained mercury, and that
contaminated waste is still being discharged into
two of the three tanks. This ROD focuses on the
contaminated sediment in the sedimentation
tanks as an interim action. Future RODs will
address principal threats posed by plant
conditions including eliminating mercury from
the storm sewer system. The primary
contaminants of concern affecting the sediment
are mercury, a metal; and radioactive materials.
SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes removing mercury-contaminated
sediment, liquids, solids, oils, and oily water
from tanks, followed by offsite treatment and
disposal; stabilizing mixed wastes from one of
the tanks, followed by onsite disposal; screening
the wastewater removed from the tanks for
hazardous and radiological contamination prior
to sediment removal, followed by onsite
treatment of the wastewater; solidifying mixed
wastes, followed by onsite storage; and
monitoring ground water and sediment. The
estimated capital cost for this remedial action is
$0, with an annual O&M cost of $586,000. This
interim remedy is expected to take only five
months to implement.

OAK RIDGE RESERVATION (USDOE)(OPERABLE UNIT 4), TN
September 19,1991
SITE HISTORY/DESCRIPTION:
The Oak Ridge Reservation (ORR) (USDOE)
(Operable Unit 4) site is a former uranium
isotope processing subsite in Oak Ridge, Roan
County, Tennessee. The 1,700-acre K-25 site,
which comprises operable unit 4 (OU4), is one of
several hundred waste disposal sites or areas of
contamination at the ORR site requiring
Superfund remedial action. Land use in the area
is predominantly residential. Three drum
storage areas are located in the northeastern
portion of the site and consist of two adjacent
asphalt pads covering six acres on the north side
of Mitchell Branch, a small stream. A curb
surrounding the pads directs water to a catch
basin for each yard, all of which discharge to
Mitchell Branch. Built in the 1940's, the K-25 site
was used to separate uranium isotopes by
gaseous diffusion with placement of resulting
wastes and sludge in collection ponds. The
storage yards were constructed to temporarily
store sludge that was removed, stabilized, and
drummed during closure of the collection ponds
from 1987 to 1989. The storage yards contain
36,000 ninety-gallon drums of stabilized sludge,
29,000 ninety-gallon drums of raw sludge, and
16,000 gallons of raw sludge in tanks,
contaminated with mixed radioactive and
hazardous wastes. The drums have started to
deteriorate and develop pin hole leaks resulting
in the release of small quantities of liquids to the
pads. In addition, depressions have been
observed in the asphalt pads causing stacked
drums to lean. This ROD addresses the sludge
stored at the storage yards as an interim action
to prevent or mitigate releases to the
environment. Future RODs will address sludge
remediation and disposal. The primary
contaminants of concern affecting the sludge are
metals and radioactive materials.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes eliminating free liquids in
sludge through filter press, thermal drying, or
similar methods; repacking dry sludge, followed
by onsite storage of containers in existing or new
indoor facilities awaiting remediation and
disposal; and processing liquids removed from
the sludge through existing treatment facilities.
The estimated capital cost for this remedial
action is $69,000,000, with an annual O&M cost
of $400,000. This interim remedy is expected to
take 20 months.

PETROLEUM PRODUCTS, FL
Octobers, 1990
SITE HISTORY/DESCRIPTION:
The Petroleum Products site is an inactive oil
processing plant in Pembroke Park, Broward
County, Florida. The area surrounding the site
is highly developed with industrial, commercial,
and residential properties. The Petroleum
Products (PPC) site lies within the radius of two
major municipal wellfields. Current site features
include an industrial warehouse complex, a
fenced area with several dozen drums of
investigation-derived waste, a french drain
system, and several monitoring and abandoned
storm drainage wells. PPC began onsite
operations as a processor and broker of waste oil
in 1958. Several tanks were located in a tank
farm area bounded on the east and north by
several large areas of standing water, which
served as a culvert drainage system. Sludge
generated during oil refinery processes was
disposed of onsite in unlined disposal pits. In
1970, a major rainfall caused the onsite disposal
pit to overflow, producing an oil slick on the
lakes of a nearby trailer park. Subsequently, all
disposal pits were filled in, but it is suspected
that sludge was mixed with clean fill and
returned to the pit or spread over the property.
Drainage at the site was then upgraded to a
french drain system and drainage wells, which
relieved flooding of the site and permitted
flushing of former disposal pit contamination
into the ground water. In 1971, PPC ended all
onsite refining operations. The property was
subsequently used as a storage and distribution
facility. In 1979, at the request of the County,
PPC cleaned up portions of the site including
two oil-soaked areas. In 1983, the State required
PPC to remove additional waste oils and submit
a detailed site sampling plan. Subsequent
sampling identified that the ground water had
been contaminated by oils, VOCs, petroleum
hydrocarbons, and inorganic compounds. In
addition, a State investigation conducted in 1984
revealed that 20,000 to 60,000 gallons of free oil
were present in a ground water plume centered
on the tank farm area and that fluctuations in
the water table had led to soil contamination by
these oils. In response to an 1985 Administrative
Order (AO), PPC emptied, cleaned, and rendered
inoperable all tanks; tested all oil, water, and
sludge before disposal or recycling; removed and
encapsulated asbestos from a boiler house; and
transported 262 drums of sludge offsite. In 1985,
the State installed a free product recovery system
to recover oil floating under the site, and a
concrete pit was installed in an onsite warehouse
to contain free oil seeping up through the floor.
This ROD addresses the first operable unit
(OU1), enhancement of the free product recovery
system as an interim remedy. A future ROD
will address source control and ground water
treatment. The primary contaminants of concern
affecting the site are metals including chromium
and lead; and oils.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
abandoning the damaged monitoring wells that
remain onsite; abandoning the storm drainage
wells onsite, which put the Biscayne aquifer at
risk; monitoring private wells in the vicinity;
enhancing the present free product recovery
system to remove a larger volume of oil and to
contain the contaminated ground water plume;
and disposing of waste oil offsite at an approved
refinery. The estimated capital cost for this
remedial action is $660,000, with an estimated
O&M cost of $83,000.
PERFORMANCE STANDARDS OR GOALS:
This interim remedy will enhance the free
product recovery system and reduce the threat of
contaminant migration into municipal wells;
therefore, clean-up goals were not provided.

SANGAMO/TWELVE-MILE/HARTWELL PCB, SC
December 19,1990
SITE HISTORY/DESCRIPTION:
The 253-acre Sangamo/Twelve-Mile/Hartwell
PCB site consists of seven separate disposal areas
in Pickens County, South Carolina. These areas
consist of the Sangamo Plant area and six private
disposal areas located offsite of the Sangamo
Plant, which are designated as the Breazeale,
Nix, Dodgens, Cross Roads, John Trotter, and
Welborn areas. Land in the general area is
predominantly forested, and there are several
nearby lakes and streams including Lake
Hartwell and the Twelve-Mile Creek basin.
Since 1955, Sangamo Weston, Inc., has
manufactured electrolytic, mica, and power
factor capacitors. PCBs were used as dielectric
fluid in power factor capacitors. Prior to 1972,
waste materials containing PCBs were land filled
in the seven disposal areas. These
PCB-contaminated materials included scrap
capacitors and aluminum hydroxide sludge from
an onsite wastewater treatment plant. In the
mid-1970's, State and Federal environmental
monitoring programs led to the detection of
PCBs in the sediment of Lake Hartwell, in its
tributaries, and in the soil of Sangamo Weston's
dump sites. In addition, PCBs were detected in
fish samples at two sites in the Twelve-Mile
Creek area of Lake Hartwell, In 1980, Sangamo
Weston, Inc., removed a total of 17,711 cubic
yards of PCB-contaminated soil and debris from
the Nix and Dodgens areas, and disposed of it in
a landfill on the Sangamo Plant property. In
1986, a geotextile liner and soil cap were
installed as an interim measure to retard the
migration of PCB contamination from the
Breazeale site. In 1989, EPA removed offsite
7,285 tons of PCB-contaminated soil and debris
from the Sangamo Plant area to a RCRA landfill,
and 6,684 capacitors were taken to an offsite
incinerator. This ROD addresses the first of two
operable units, and provides for remediation of
the ground water and source contamination at
the seven disposal areas. A future ROD will
address the contamination of the Twelve-Mile
Creek basin and Lake Hartwell. The primary
contaminants of concern affecting the soil,
sludge, debris, and ground water are VOCs
including PCE and TCE; and other organics
including PCBs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating materials contaminated with greater
than 1 mg/kg of PCBs at the Nix and Welborn
areas; excavating materials contaminated with
greater than 25 mg/kg of PCBs at the Sangamo
Plant area; excavating materials contaminated
with greater than 10 mg/kg of PCBs at the
Breazeale, Dodgens, Cross Roads, and John
Trotter areas; transporting the excavated
materials to the Sangamo Plant area for staging
and treatment; treating onsite all excavated
materials using thermal desorption technology
and carbon adsorption to control off-gases;
placing the treated soil within the Plant area;
filling each of the private areas with 2 feet of
clean fill where contaminated materials with
PCBs greater than 1 mg/kg remain, specifically
the Trotter, Dodgens, Breazeale, and Cross Roads
areas; ground water pumping and onsite
treatment at the Dodgens, Breazeale, Cross
Roads, and Sangamo Plant areas using air
stripping and/or carbon adsorption; and
discharging the treated water onsite to surface
water. The estimated present worth cost for this
remedial action ranges from $47,900,000 to
$63,300,000 depending on aquifer characteristics
and the volume of excavated solids. No O&M
costs were provided for this remedial action.

SHERWOOD MEDICAL INDUSTRIES, FL
March 27,1991
SITE HISTORY/DESCRIPTION:
The 42-acre Sherwood Medical Industries (SMI)
site is an active medical supply manufacturing
facility just outside the city limits of Deland,
Volusia County, Florida. Land use in the area is
commercial and residential. Lake Miller is along
the western boundary, and a wooded swampy
area is located to the south of the site. The
underlying Floridan aquifer, which is
restrictively connected to the contaminated
surficial aquifer, is the drinking water source for
local residents. From 1959 to present, SMI has
used the site for manufacturing medical supplies,
primarily hypodermic needles. From 1971 to
1980, SMI disposed of approximately 2 tons of
liquid and sludge waste into two unlined
percolation ponds onsite. At that time, solids
were removed from the ponds and placed into
onsite, unlined impoundments. From 1980 to
1982, SMI analyzed the contents of the
impoundments and disposed of the wastes in an
offsite landfill. Initial site investigations
conducted by SMI and the State identified
ground water contamination in onsite wells. In
1987, the State requested that SMI perform
additional investigations to determine the nature
and extent of ground water contamination, and
to evaluate the need to implement interim
remedial measures. Based on the observed
onsite contamination of the Floridan Aquifer, the
State required SMI to conduct extensive ground
water testing and monitoring, and to provide
bottled water to an affected residence. In 1990,
the State approved SMI's design work plan,
which outlined further interim measures to be
conducted at the site including installation of a
ground water pump and treat system. This ROD
addresses an interim remedy for the surficial
aquifer to prevent the contaminant plume from
spreading offsite and migrating vertically into
the Floridan aquifer. Future RODs will fully
address the principal threats posed by the
conditions at the site. The primary contaminants
of concern affecting the ground water are VOCs
including PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes installing a system of recovery
wells in the onsite surficial aquifer; and pumping
and treatment of contaminated ground water
using air stripping, followed by onsite discharge
of the treated water to Lake Miller. The
estimated capital cost for this interim remedial
action is $400,000, with an annual O&M cost of
$35,000.
PERFORMANCE STANDARDS OR GOALS:
Treated ground water will meet all Federal and
state water quality standards for discharge to
surface water. Final clean-up levels will be
addressed in a future ROD.

on a mile-long ridge between two intermittent
creeks where the unpermitted disposal of drums
containing hazardous waste occurred over a
20-year period. This area has been divided into
two areas known as Area A and Area B, As a
result of EPA investigations in 1984 that revealed
chemicals leaking from drums, EPA removed
6,000 drums of surface wastes, excavated
contaminated soil, and implemented site
stabilization and erosion prevention measures.
A 1989 ROD addressed source control in the
80-acre area through thermal destruction.
Investigations during the RD revealed lower
levels of PCBs and a lower volume of soil
requiring treatment than what was previously
estimated in the RI, making incineration less
practical. This ROD amends the 1989 ROD and
provides source control in the 80-acre area using
chemical treatment, rather than thermal
treatment. A second operable unit will address
remaining potential threats associated with the
landfill, deep ground water aquifers, and other
suspected areas of drum disposal. The primary
contaminants of concern affecting the soil,
sediment, and debris are organics including
PCBs and PAHs, and metals including lead.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes excavating 16,000 cubic yards of
contaminated soil and excavating contaminated
stream sediment in Area B, as defined in the
RI/FS; treating Area B soil and sediment onsite
by a chemical process, possibly dechlorination or
hydrocarbon removal using APEG or BEST,
respectively, and by a solidification/fixation
process; overpacking debris from Area B and
disposing of the overpacked debris and all
treated soil and sediment from Area B onsite
within Area A; consolidating the contaminated
soil, sediment, and debris from peripheral areas
of Area A into Area A; recontouring Area A;
constructing and maintaining retaining walls,
surface run-on/run-off control systems, and a
leachate collection system in Area A, with onsite
or offsite treatment and disposal of leachate;
capping Area A with a RCRA cap after all
material from Area A and B have been disposed
of in Area A; monitoring ground water; and
implementing institutional controls including
land use restrictions, and site access restrictions.
The estimated present worth cost for this
remedial action ranges from $22,000,000 to
$25,000,000, based on the treatment selected.
O&M costs were not provided.
PERFORMANCE STANDARDS OR GOALS:
Action levels for contaminated soil and/or
sediment were determined based on an excess
lifetime cancer risk of 10"5, with the exception of
lead, which was based on an HI<1. Chemical-
specific goals for soil include PAHs 2 mg/kg
and lead 500 mg/kg; and for sediment PAHs
5 mg/kg and PCBs 2 mg/kg.
INSTITUTIONAL CONTROLS:
Land use restrictions will be implemented onsite
to limit further site use.

TRI-CITY INDUSTRIAL DISPOSAL, KY
August 28,1991
SITE HISTORY/DESCRIPTION:
SELECTED REMEDIAL ACTION:
The 349-acre Tri-City Industrial Disposal site is
an inactive industrial waste landfill located in
Brooks, Bullitt County, Kentucky. Land use in
the area is predominantly agricultural and
residential. The estimated 300 people who reside
within 1 mile of the site use ground water from
a thin unconfined limestone aquifer as their
drinking water supply. Ground water
discharges via several springs including the Cox
and Klapper Springs. From 1964 to 1967,
Tri-City Industrial Services, Inc., used the site to
dispose of industrial waste including scrap
lumber, fiberglass insulation materials, drummed
liquid wastes, and bulk liquids that were poured
onto the ground. In 1968, State officials reported
that highly volatile liquid wastes resembling
paint thinners were disposed of onsite. The site
was a source of citizen complaints about the
condition of the landfill, explosions, fires, and
smoke during the disposal operations. A
number of State and EPA investigations that
were conducted between 1965 and 1989
identified contaminants including PCBs, phenols>
metals, and various organic compounds in onsite
soil, wastes, and residential springs. In 1988,
EPA provided local residents with an alternate
water supply, and conducted an emergency
removal action to excavate and remove
approximately 165 drums in generally good
condition, other crushed and empty drums,
metal containers, auto parts, 400 gallons of free
liquids, and over 800 cubic yards of suspected
contaminated soil. This ROD addresses ground
water contamination as operable unit 1 (OU1).
Should the confirmatory sampling of soil,
sediment, and air conducted in OU1 reveal
unacceptable levels of hazardous contaminants,
additional measures may be necessary and will
be implemented as OU2. The primary
contaminants of concern affecting the ground
water are VOCs including PCE, TCE, DCE,
toluene, and vinyl chloride.
The selected remedial action for this site includes
installing a carbon adsorption system at the Cox
Spring; treating contaminated ground water
using carbon adsorption and discharging the
treated ground water to tributaries downstream
of the springs; conducting a teachability test to
determine whether spent carbon is a hazardous
waste; regenerating, or treating and disposing of
spent carbon offsite; continuing to provide
potable water to residents who previously used
contaminated ground water as potable water
until acceptable levels are reached; confirmatory
sampling of soil, sediment, and ambient air to
assess the effectiveness of EPA's 1988 Emergency
Removal Action; long-term monitoring of ground
water, surface water, sediment, and ecology;
implementing a worker health and safety
program; and implementing institutional controls
including ground water use restrictions. The
estimated present worth cost for this remedial
action is $2,098,000, which includes an annual
O&M cost of $89,890 for years 0-1, $70,686 for
years 2-3, and $66,330 for years 4-30.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs or non-zero MCLGs,
and include PCE 5 ug/1 (MCL), TCE 5 ug/1
(MCL), toluene 1,000 ug/1 (MCL), and xylenes
10,000 ug/1 (MCL).
INSTITUTIONAL CONTROLS:
Ground water restrictions will be implemented
to restrict the potable use of ground water
containing or potentially containing levels of
contamination above MCLs or non-zero MCLGs.

USA ANNISTON ARMY DEPOT, AL
September 26,1991
SITE HISTORY/DESCRIPTION:
The 15,200-acre USA Anniston Army Depot site
is an active equipment rework facility for the
U.S. Army in Anniston, Calhoun County,
Alabama. The site is divided into several areas
including a southeast industrial area, which is
the focus of this ROD. Land use in the area is
predominantly residential. An estimated 72,000
residents in Calhoun County use Coldwater
Springs, located 1.5 miles south of the site, as
their primary source of drinking water. The
Army initially used the depot to store munitions,
and subsequently, to overhaul and repair combat
vehicles. Various types of liquid and solid
hazardous wastes were generated, including
electroplating wastes containing metals and
organic solvents from cleaning operations.
Wastes were disposed of in various landfills,
trenches, disposal pits, and lagoons located in
the southeast industrial area and throughout the
site. A number of EPA and State investigations
have revealed contamination by VOCs, other
organic compounds, inorganics, and metals in
the onsite ground water. Between 1978 and
1983, several onsite actions were taken by the
Army to remove contaminated sludge and soil.
In 1990, the Army completed and began
operation of a ground water pumping and
treatment system. This ROD addresses an
interim remedy for ground water contamination
beneath the southeast industrial area as the first
operable unit. Future RODs may address further
contamination in the southeast industrial portion
of the site. The primary contaminants of concern
affecting the ground water are VOCs including
PCE and TCE; other organics including phenols;
and metals including chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continued use the existing ground water
pumping and treatment system using air
stripping to remove VOCs, followed by charcoal
filtration to remove phenols; discharging the
treated ground water onsite to surface water;
and continued operation of the dewatering and
treatment system. The estimated present worth
cost for this remedial action is $945,000, which
includes an annual O&M cost of $60,000. The
capital cost is estimated at $895,000.

June 25, 1991
SITE HISTORY/DESCRIPTION:
The 46.5-acre USAF Robins Air Force Base site is
a logistics management and repair center for
aircraft, missiles, and support systems in Warner
Robins, Houston County, Georgia. The Zone 1
area, which includes a 45-acre inactive landfill
and a 1.5-acre sludge lagoon is part of the
8,855-acre Robins Air Force Base. Land use in
the area is mixed residential and industrial. A
wetlands area borders the site to the east; in
addition, part of the site lies within the 100-year
floodplain of the Ocmulgee River. From 1965 to
1978, an onsite landfill (Landfill No. 4) was used
for disposal of general refuse, and industrial and
hazardous wastes. From 1962 to 1978, the sludge
lagoon was used for disposal of wastewater
treatment plant sludge and other liquid wastes.
Types of wastes generated at the facility
included electroplating wastes, organic solvents
from cleaning operations, and pesticides, all of
which were disposed of in the lagoon and
landfill areas. Robins Air Force Base conducted
a study in 1982 to identify and assess onsite
hazardous waste disposal practices. Disposal
areas were grouped into eight zones based on
location and type of activity. Zone 1 has been
divided into three operable units (OUs). This
ROD, which focuses on OU1, addresses the
remediation of Landfill No. 4 and the sludge
lagoon. Subsequent RODs will address
remediation of the neighboring wetlands and
surface waters (OU2), the ground water adjacent
to Landfill No. 4, and the sludge lagoon (OUS).
The primary contaminants of concern affecting
the soil, sludge, and ground water are VOCs
including PCE and TCE; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating 15,000 cubic yards of soil in the sludge
lagoon using in-situ soil vapor extraction;
removing volatile contaminants from the air
using condensation, distillation, and carbon
adsorption; controlling and treating landfill
leachate; renovating the landfill cover; treating
the sludge lagoon to remove VOCs, treating
metals onsite in the sludge lagoon using
solidification; onsite pumping and treatment of
ground water; diverting surface water near the
sludge lagoon; conducting long-term soil testing;
and monitoring ground and surface water. The
estimated present worth cost for this remedial
action ranges from $9,430,000 to $24,000,000, with
an annual O&M cost ranging from $321,400 to
$334,400, depending on the components of the
landfill cap.
PERFORMANCE STANDARDS OR GOALS:
Contaminant-specific remediation goals have not
been established for soil at the sludge lagoon
because they are dependent on establishment of
ground water goals, which will be developed in
a subsequent ROD.

VELSICOL CHEMICAL, TN
June 27,1991
SITE HISTORY/DESCRIPTION:
The 242-acre Velsicol Chemical site is a former
plant waste landfill located near the City of
Toone, Hardeman County, Tennessee. Land use
in the area is predominantly agricultural with a
wetlands area, 26 residences, and numerous
creeks located within 1 mile of the site. In
addition, part of the site overlies a surficial
aquifer that was used as a potable water supply
in the area. From 1964 to 1973, Velsicol
Chemical Corporation used the site to dispose of
industrial and chemical plant wastes. Waste was
disposed of in trenches excavated on 27 acres of
the property. The site was closed in 1973
because of the possibility of contaminated
ground water migrating offsite. By late 1978,
State and Federal investigations had confirmed
ground water contamination in private wells,
and a public water supply was provided in early
1979. In 1980, a 35-acre low permeability clay
cap was placed over the disposal area to control
and minimize additional impacts from the site.
This ROD addresses offsite ground water
contamination, as operable unit 1 and will
prevent additional onsite ground water
contamination from migrating from the disposal
areas. Future RODs will address other site
contamination and principal threats, The
primary contaminants of concern affecting the
ground water are VOCs including carbon
tetrachloride, chloroform, toluene, and xylenes;
ar>d other organics including pesticides,
.SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
'^stalling extraction wells onsite and offsite to
restore the contaminated ground water to
acceptable drinking water standards;
constructing an onsite ground water treatment
plant and treating contaminated ground water
using solids removal, air stripping, and final
ground water polishing prior to discharge;
discharging the treated water onsite to nearby
surface water bodies; treating off-gases with
carbon adsorption; monitoring ground water;
maintaining the ground water treatment system
and the disposal area cover; and implementing
institutional controls including deed and ground
water use restrictions. The selected remedial
action is contingent upon the performance data
collected during operation. If the selected
remedy cannot meet the specified remediation
goals, contingency measures may include
alternating pumping at wells to eliminate
stagnation points; pulse pumping at wells to
allow aquifer equilibration and encourage
adsorbed contaminants to partition into ground
water; and installing additional extraction wells
to facilitate or accelerate cleanup of the
contaminant plume. The estimated present
worth cost for this remedial action is $11,644,000,
which includes an annual O&M cost of $696,000.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs and health-based
criteria, and include carbon tetrachloride
0.005 mg/1 (MCL), chloroform, 0.006 mg/l,
toluene 1 mg/l (MCL), and xylenes 10 mg/1

WRIGLEY CHARCOAL, TN
September 30,1991
SITE HISTORY/DESCRIPTION:
The 81-acre Wrigley Charcoal site is a former
multi-use industrial operations area in the town
of Wrigley, Hickman County, Tennessee. Land
use in the area is industrial and residential, with
approximately 1,000 people residing within a
one-mile radius of the site. From 1881 to 1985,
the site has been used mainly for pig iron and
wood retorting/wood distillation by-product
manufacturing. Additional activities conducted
between 1978 and 1985 included usage of several
remaining onsite buildings for metals machining,
copper recovery, and storage of drummed
industrial wastes. Improper disposal procedures
have resulted in soil, sediment, and debris
contamination by semi-volatile organic
compounds in coal-tars (mainly PAHs and
phenols), VOCs, metals, and asbestos. EPA
investigations have identified four major areas of
onsite contamination. These four areas are as
follows: the 35-acre Primary Site containing
coal-tar contaminants; the 3-acre Storage Basin
area that also contains coal tar contaminants; the
40-acre Irrigation Field (including an abandoned
wastewater lagoon) that was used for spray
irrigation (disposal) and degradation of PAH
and phenolic wastewaters; and the 3.5-acre
Athletic Field, a field used by local residents,
which is filled with blast furnace slag and soil
derived from the Primary Site from 1938 to 1950.
The Primary Site was an industrial production
facility for iron, charcoal, and wood distillation
products from 1888 to 1966. The Primary Site
was later used for metals machining, storage of
waste products, and recovery of copper from
transformers. The Storage Basin and Irrigation
Held were built in the late 1950's to receive
wastewater from the Primary Site. In 1988, EPA
performed a removal activity, which stabilized
the site by installing clay backfilled culverts
covered with erosion control fabric; installing
sheet piling to stabilize the banks; retaining the
tar pits; removing 8 cubic yards of asbestos
material; solidifying approximately 130 cubic
yards of tar pit wastes, followed by offsite
incineration of the solidified material;
establishing a vegetative cover for the tar pit
cover; constructing a spillway; and offsite
landfilling of debris. This ROD addresses
interim remediation of remaining contaminated
soil, sediment, and debris, and will reduce the
risks at the Primary Site and Storage Basin by
eliminating the most imminent and substantial
threats while permanent solutions are developed
for the entire site. Future RODs may address
remediation of the contaminated Primary Site
soil, tar pits and tar cubes, as well as the Storage
Basin; coal-tar wastes, friable asbestos-corrugated
roofing material (ACM), and any onsite ground
water problems. The primary contaminants of
concern affecting the soil are VOCs; other
organics including PAHs, and phenols; metals
including arsenic, chromium, and lead; and
asbestos, an inorganic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, stabilizing, and disposing of offsite
approximately 15 cubic yards of metallic wastes
from the burn pit; consolidating and securing
onsite approximately 120 drums of transformers;
excavating, incinerating, stabilizing, and
disposing of offsite 14 waste drums, 29 cubic
yards of process tank sludge, and 122.5 cubic
yards of black coal tar wastes located in three
separate areas; decontaminating the tanks;
excavating and disposing of visibly friable
asbestos material in the soil and buildings within
the Primary Site; re-engineering of the spillway
to accommodate flood waters; sorting and
disposing of site surface wastes and debris piles
(including tar-cubes; pieces of ACM, crushed
drums and metallic debris) offsite, or temporarily
consolidating these onsite for future remediation;

ACME SOLVENT RECLAIMING, IL
December 31,1990
SITE HISTORY/DESCRIPTION:
The 20-acre Acme Solvent Reclaiming site is a
former industrial disposal site in Winnebago
County, Illinois. Land use in the area is mixed
agricultural and residential. The site is bounded
by an active quarry to the north, farmland to the
south and east, and the Pagel's Pit Superfund
site to the west. An onsite stream, which is a
tributary of Kilbuck Creek, eventually drains into
the Rock River to the south. The site overlies
two aquifers, which are used by the estimated
400 residents who live within 2 miles of the site
as their drinking water supply. From 1960 to
1973, Acme Solvent Reclaiming disposed of
paints, oils, and still bottoms onsite from its
solvent reclamation plant. Wastes were dumped
into depressions created from previous
quarrying and landscaping operations, and
empty drums also were stored onsite. State
investigations in 1981 identified elevated levels
of chlorinated organic compounds in ground
water. A 1985 ROD provided for excavation and
onsite incineration of 26,000 cubic yards of
contaminated soil and sludge, supplying home
carbon treatment units to affected residences,
and further study of ground water and bedrock.
During illegal removal actions taken by PRPs in
1986, 40,000 tons of soil and sludge were
removed from the site. A 4,000-ton waste pile
and 2 tanks containing contaminated liquids
remain onsite, and since then an additional 2,000
tons of onsite contaminated soil and sludge has
been discovered. This ROD will address waste
areas remaining after the 1986 removal,
including soil, bedrock, and ground water, as
part of operable unit 2 (OU2). A future ROD
will address an area of ground water
contamination between the Acme Solvent
Reclaiming and Pagel's Pit sites as OU3. The
primary contaminants of concern affecting the
soil, sludge, and ground water are VOCs
including benzene, PCE, TCE, and xylenes; other
organics including PCBs; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and treating 6,000 tons of soil and
sludge from two waste areas using low-
temperature thermal stripping; treating residuals
using solidification, if necessary, followed by
onsite or offsite disposal; treating the remaining
contaminated soil and possibly bedrock using
soil/bedrock vapor extraction; consolidating the
remaining contaminated soil onsite with any
treatment residuals, followed by capping;
incinerating offsite 8,000 gallons of liquids and
sludge from two remaining tanks, and disposing
of the tanks offsite; providing an alternate water
supply to residents with contaminated wells;
pumping and onsite treatment of VOC-
contaminated ground water, with discharge to
surface water; monitoring ground water; and
implementing institutional controls including
deed and ground water use and restrictions.
The estimated present worth cost for this
remedial action ranges from $14,633,000 to
$16,233,000, which includes an annual O&M cost
of $908,400.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific clean-up goals for soil are
based on a lifetime excess cancer risk level of
1 x 10"5. All waste area soil exceeding
PCBs 10 mg/kg must be excavated and treated.
In addition, all soil exceeding 10 mg/kg above
background levels using a photoionization
device will be excavated. Any soil remaining
after excavation and residuals landfilled onsite
must meet the site-specific VOC clean-up
standards including benzene 69 ug/kg,
TCE 140 ug/kg, and PCE 1,200 ug/kg.

ALLIED CHEMICAL AND IRONTON COKE, OH
December 28,1990
SITE HISTORY/DESCRIPTION:
The 95-acre Allied Chemical and Ironton Coke
site is composed of a former coke plant and an
operating tar plant in Ironton, Lawrence County,
Ohio. The site is located within a coal mining
region, and surrounding land use is
predominantly industrial and residential. The
Ohio River, a source of drinking water for the
city of Ironton, lies approximately 500 feet to the
west of the tar plant. Onsite lagoons lie within
the 100-year floodplain of the Ohio River, with
portions of the lagoons inundated sufficiently to
maintain wetlands vegetation. From
approximately 1920 to the late 1960's, wastewater
and solid wastes including coke and coal fines,
tank car sludge, boiler ash, and weak ammonia
liquor were discharged into swampy areas east
of the Coke Plant, which are adjacent to Ice
Creek, a tributary to the Ohio River. From the
early 1970's until the coke plant closed in 1982,
a series of four lagoons in the eastern area of the
plant were used to treat process wastewaters,
stormwater run-off, and waste sludge; and a fifth
lagoon was used to dispose of solid waste. Tar
plant operations began onsite in 1945. Types of
wastes generated included anthracene residues
and salts, coal tar pitch scrap, and phthalic
anhydride residues, which were disposed of
onsite in the Goldcamp Disposal Area, a former
sand pit adjoining the tar plant. Extensive
studies and onsite investigations identified
contamination in onsite soil in the Coke Plant
and tar plant areas, lagoon sediment, Ice Creek
sediment downstream of the site, and ground
water beneath and surrounding the site. A 1988
ROD addressed the Gold Camp Disposal Area
and documented installation of a cap and slurry
wall, pumping and treatment of contaminated
ground water, and provisions for supplemental
study and remediation of nonaqueous phase
contaminants found on top of the bedrock. This
ROD addresses contamination at all areas not
previously addressed, and provides a final
remedy at the site. The primary contaminants of
concern affecting the soil, sediment, and ground
water are VOCs including benzene; other
organics including PAHs and phenols; metals
including arsenic; and other inorganics including
cyanide.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and incinerating onsite approximately
122,000 cubic yards of waste material from
Lagoon 5, and 31,000 cubic yards of waste coal,
followed by onsite waste fuel recovery (re-use of
the waste heat generated during incineration),
and disposing of the residual ash offsite; in-situ
bioremediation of approximately 475,000 cubic
yards of waste material from Lagoons 1 through
4, the residual soil of Lagoon 5, and the adjacent
inner and outer dikes; excavating and onsite
bioremediation on a prepared pad of
approximately 40,000 cubic yards of soil from the
Coke and tar plant soil; pumping and treatment
of ground water at a future onsite treatment
facility, with onsite reinjection or offsite
discharge; monitoring ground water onsite and
downgradient of Ice Creek, and developing a
contingency plan in the event that contaminant
migration is encountered; pilot testing the
effectiveness of in-situ bioremediation and
developing a contingency plan for an alternative
remedial action for Lagoons 1 through 4, if
necessary; and implementing institutional
controls including deed restrictions, and site
access restrictions such as fencing. The
estimated capital cost for this remedial action is
$21,000,000, with an estimated total O&M cost of
$28,500,000. Total estimated cost is $49,500,000.

ANDERSON DEVELOPMENT (AMENDMENT), Ml
September 30,1991
SITE HISTORY/DESCRIPTION:
The Anderson Development site is an active
chemical manufacturing facility in Adrian,
Lenawee County, Michigan. The site occupies
approximately 12.5 acres within a 40-acre
industrial park, which is surrounded by
residential areas. Site features include several
onsite buildings used for manufacturing, storage,
laboratories, and offices, as well as a 0.5-acre
former process wastewater pretreatment lagoon
containing lagoon sludge and an underlying clay
layer. From 1970 to 1979, the Anderson
Development Corporation (ADC) produced
specialty chemicals onsite including
4,4-methylene bis (2-chlororaniline) (MBOCA), a
hardening agent for the production of
polyurethane plastics. Untreated process
wastewater was discharged directly to surface
water until 1973, when the State discovered
aniline in a side drain from the facility. Later in
1973, ADC began separating process wastewater
from its cooling water, with subsequent
discharge of wastewater to a POTW. At the
POTW, MBOCA was settled out with other
solids and applied to the land, which has led to
contamination at the POTW drying beds. In
1979, the State ordered the POTW not to accept
the waste stream because of the decreased
efficiency of the POTW resulting from MBOCA
contamination. In 1979, after MBOCA was
found in onsite sediment, production of the
chemical ceased. In 1980 and 1981, the site
owner and the State cleaned up all contaminated
site areas, except for the onsite lagoon and the
adjacent soil, with MBOCA levels greater than 1
mg/kg by decontaminating the plant, sweeping
streets, shampooing/vacuuming residential
carpet, and removing some contaminated surface
soil offsite. A 1990 ROD addressed site
contamination of surface soil, lagoon sludge, and
underlying lagoon clay. This ROD amends the
1990 ROD, which provided for treatment of the
contaminated media using in-situ vitrification,
and documents the selection of low temperature
thermal desorption (LTTD) as the preferred
treatment technology, based on cost and other
concerns. The primary contaminants of concern
affecting the soil and lagoon sludge are VOCs
including toluene and MBOCA and its
degradation products; and metals.
SELECTED REMEDIAL ACTION:
The selected amended remedial action for this
site includes excavating and staging 3,000 to
4,000 tons of contaminated soil, clay, and lagoon
sludge with MBOCA concentrations above the
1.6 mg/kg clean-up action level in an LTTD
device; performing treatability studies to
evaluate effectiveness of the LTTD technology,
then, if effective, treating the contaminated soil,
clay, and sludge onsite using LTTD; placing the
treated soil, sludge, and clay into the excavated
lagoon, covering the lagoon with clean soil, and
regrading the area; or if the results of the
treatability study indicate that LTTD is
unacceptable, using in-situ vitrification as the
alternate remediation technology; collecting
off-gases and treating the gases using an air
pollution control train, which includes a scrubber
system, air filters, and carbon adsorption beds;
treating aqueous streams from the air pollution
control train using liquid phase activated carbon
beds; thermally regenerating or disposing of
spent carbon and fines from the particulate
removal equipment offsite; and monitoring
ground water and air. The estimated cost of the
LTTD treatment options for this amended
remedial action is $1,100,000.

BERLIN & FARRO, Ml
September 30,1991
SITE HISTORY/DESCRIPTION:
The 40-acre Berlin and Farro site is a former
liquid incineration and landfill facility in Gaines
Township, Genesee County, Michigan. Land
near the site consists of woodland and
agricultural areas. In addition, the site overlies
two aquifers, which provide well water to the
approximately 80 permanent homes located
within a 1/2 mile radius of the site. From 1971
to 1975, Berlin and Farro Liquid Incineration,
Inc., used the site to accept and store industrial
wastes prior to incineration, and disposed of
crushed drums in a 1.1-acre onsite landfill.
During this period, the owners failed to comply
with air emission standards, onsite storage
volume limits, and permit standards that
prohibited onsite disposal of wastes other than
solid wastes. The facility also operated two
unauthorized waste storage lagoons and two
unlined storage lagoons; illegally buried five
tanks of wastewater and liquid wastes; operated
underground storage tanks; poured liquid wastes
into subsurface agricultural drains; and dumped
thousands of gallons of barrelled wastes into two
onsite pits. In 1975, Berlin and Farro's permits
were revoked; however, illegal dumping of
industrial waste into the lagoons apparently
continued after the site was closed. Several
separate clean-up actions were undertaken by
the PRPs, the State, and EPA during the early to
mid-1980's. These activities included, but were
not limited to, removing lagoon sludge, the
incinerator facility, five underground tanks, an
agricultural drain and paint sludge trench,
surface debris, drums, waste piles and soil, and
1,000,000 gallons of contaminated water;
backfilling the lagoons and old drum landfill;
and constructing settling ponds. This ROD
addresses the final remedy for contaminated soil,
sediment, and ground water at the Berlin and
Farro site. The primary contaminants of concern
affecting the soil, sediment, and ground water
are VOCs including
benzene, PCE, TCE, toluene, and xylenes; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, partially treating using solidification,
and consolidating (in an onsite RCRA
containment cell) contaminated soil and
sediment from the central site area and sediment
from an offsite drain (treatment of the materials
will remove free liquids and render characteristic
waste and non-characteristic RCRA waste);
collection and treating leachate from the cell;
backfilling, covering with soil and revegetating
the excavated onsite areas; regrading the
excavated areas of the drain; pumping and
treatment of ground water from the shallow
portion of the aquifer using a system of
collection trenches, followed by treatment using
air stripping and onsite discharge to the drain;
treating off-gas emissions from the ground water
treatment system; monitoring ground water; and
implementing institutional controls including
deed restrictions. The estimated present worth
cost for this remedial action is $8,119,300, which
includes an annual O&M cost of $233,100 for 30
years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil and sediment clean-up
goals are based on State health-based standards
and include benzene 0.02 mg/kg, lead 20.8
mg/kg, toluene 16 mg/kg, and xylenes 6 mg/kg.
Chemical-specific ground water clean-up goals
are based on health standards, and include
benzene 1 ug/1.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
the installation of drinking wells on the site
during remediation.

BETTER BRITE PLATING CHROME & ZINC, Wl
June 28,1991
SITE HISTORY/DESCRIPTION:
The 2-acre Better Brite Plating Chrome & Zinc
site is composed of two plating facilities in De
Pere, Brown County, Wisconsin. The site
includes the 1.5-acre Chrome Shop and the
0,5-acre Zinc Shop, which are located
approximately 0.5 miles apart. Because of their
proximity and related backgrounds, the two sites
were jointly nominated to the National Priority
List and are addressed as a single site in this
ROD. Land use in the area is predominantly
residential and commercial, with a wetlands
located approximately one-quarter mile from the
site. The estimated 15,000 area residents use the
municipal wells drawing from the deep aquifer
as a drinking water supply. A municipal well
located approximately 250 feet from the site is
thought to influence the ground water flow in
the contaminated shallow aquifer, but impacts
have not been observed in the municipal well
onsite. From 1963 to the early 1970% the Zinc
Shop primarily plated chrome, switching later to
zinc. The Zinc Shop has a long history of
improper operational procedures and spills into
the surrounding soil. Wastewater and/or
plating solutions routinely leaked between the
floor and sill plate of the building. Reportedly,
underground vertical plating tanks were used
early on. The Chrome Shop began chrome
plating operations during the early 1970's using
several above-ground tanks and four buried
vertical tanks in the plating process. In 1978 and
1979, the Chrome Shop was found to be
responsible for surface spills, which resulted in
construction of a shallow ground water
extraction system around a portion of the site.
Later, it was determined that the underground
plating tanks from the Chrome Shop had leaked
an unknown amount of plating solution and
VOCs into the onsite ground water.
Consequently, in 1985, the owner of the Chrome
Shop filed for bankruptcy and operations ceased
m 1986. In 1987, the State installed ground
water monitoring wells at the site, which
identified contamination by metals and VOCs in
soil and ground water. In 1989, the Zinc Shop
closed, and a private contractor removed the
building that housed the Chrome Shop. The
State constructed a clay cap and fenced around
the area of highest soil contamination. In 1990,
the Zinc Shop owner failed to comply with an
AO to conduct clean-up activities. Subsequently,
EPA performed an emergency removal action,
which included shipping 350 cubic yards of
hazardous and solid waste offsite and
constructing a ground water collection sump.
Ground water is collected, stored temporarily,
and treated onsite. The residual chromium
sludge from the ground water treatment is sent
offsite for recycling. Later in 1990, EPA
performed an additional emergency response,
and provided for the construction of a
wastewater pretreatment system and an
extraction system to collect and pretreat shallow
ground water prior to discharge offsite to the De
Pere wastewater system. This ROD addresses
operable unit 1, contaminated ground water and
surface water, as an interim action. Future
RODs will address remaining soil and ground
water contamination. The primary contaminants
of concern affecting the ground water and
surface water are VOCs including 1,1,1-TCA and
1,1-DCA; other organics; and metals including
chromium, cyanide, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes continuing and expanding the
current operation of the ground water extraction
system and pretreatment facility, which will
include pretreatment of the additional water
collected by the surface water and ground water
collection systems, and the Chrome and Zinc
shops, with discharge to the De Pere wastewater
system; improving surface water drainage, and
constructing berms to control surface water run-

BUCKEYE RECLAMATION, OH
August 19,1991
SITE HISTORY/DESCRIPTION:
The 658-acre Buckeye Reclamation site contains
a 50-acre former landfill in Richland Township,
Belmont County, Ohio. Land use in the area is
predominantly agricultural, rural residential, and
strip mining. A total of 46 domestic wells and
springs are located within 1 mile of the site. The
site is situated in the King's Run drainage
ravine, and is bordered by King's Run to the east
and Unnamed Run to the west. King's Run
flows to the south into Little McMahon Creek.
The original topography of the valley has been
altered by coal mining and landfill operations.
Prior to 1940, the site served as a disposal area
for coal mine refuse. The county licensed the
area as a public solid waste landfill in 1971, and
the facility accepted general trash, rubbish, and
nonhazardous waste. The landfill also accepted
industrial sludge and liquids, most of which
were received between 1976 and 1979, and
deposited in the Waste Pit located in the
northern section of the landfill. Solid industrial
wastes also were disposed of along with
municipal wastes elsewhere in the landfill. In
1980, the Waste Pit was filled with sludge, mine
spoil, and overburden soil; covered with soil and
garbage; and seeded. Results of the RI indicate
various levels of contamination in all media
sampled, except air. This ROD addresses the
remediation of contaminated leachate and
ground water and eliminates exposure to
contaminated surface soil. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, TCE,
and toluene; other organics including PAHs; and
metals including arsenic, chromium, beryllium,
and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the entire landfill area including the
Waste Pit and suspected sources of recharge for
the Waste Pit and water bearing zones, with a
solid waste landfill cap; installing a leachate seep
and ground water collection system; treating
collected wastewaters with constructed wetlands
and discharging the treated waters onsite to
Little McMahon Creek; conducting long-term
ground and surface water monitoring; and
implementing institutional controls including
deed, land, and ground water use restrictions, as
well as site access restrictions including fencing.
The estimated present worth cost for this
remedial action is $48,663,000, which includes an
annual O&M cost of $99,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
EPA is invoking a waiver of RCRA closure
requirements due to the steepness of the landfill
slopes, which makes construction of a RCRA
Subtitle C cap technically impracticable.
Contaminants discharged from the wetlands
treatment system will not exceed NPDES
discharge limits. The limits may be modified to
more stringent levels if proven feasible.
INSTITUTIONAL CONTROLS:
Deed, land, and ground water use restrictions
will be implemented at the site.

CARTER INDUSTRIALS, Ml
September 18,1991
SITE HISTORY/DESCRIPTION:
The 3.5-acre Carter Industrials site is a former
scrap metal storage and salvage operation in
Detroit, Michigan. Surrounding land use is
mixed residential and light industrial in an
urban setting, Onsite features include several
buildings, two shelters, an incinerator, a
1,000-gallon underground gasoline storage tank,
and seven piles consisting of approximately
46,000 cubic yards of PCB-contaminated soil and
debris. From 1966 until 1986, the site was used
as a scrap metal salvage and storage facility,
changing ownership several times during the
period. Items accepted for salvage included
electrical capacitors and transformers. During
salvage operations, dielectric fluid containing
PCBs was spilled from the capacitors and
transformers directly onto the onsite soil.
Adjacent commercial, residential, and municipal
properties have been contaminated by direct run-
off of spilled material, storm water run-off,
wind-blown dust, and tracking of spilled
material by vehicles. In 1986, the State identified
elevated levels of PCBs in onsite soil, which was
later confirmed by EPA investigations.
Consequently, in 1986, as part of a removal
action, EPA stabilized the site by diverting
surface water run-off to onsite interception
trenches and a treatment system; excavating and
consolidating onsite contaminated soil and debris
along with offsite residential debris into seven
onsite piles; decontaminating and disposing of
debris offsite; decontaminating alleys and streets
within a 4-square block area; and fencing the
site. Also in 1986, the State removed and
disposed of all PCB-contaminated soil with levels
between 10 to 50 mg/kg from surrounding
residential areas offsite. In 1989, the PRPs
covered onsite piles of contaminated material
with geotextile and vegetative cover to provide
temporary containment. This ROD addresses
remediation of remaining onsite and offsite
source material. A subsequent ROD will address
the need for remediation of contaminated sewer
lines running from the site. The primary
contaminants of concern affecting the soil and
debris are organics including PCBs; and metals
including arsenic, cadmium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating approximately 46,000 cubic yards of
onsite and offsite soil contaminated with greater
than 1 mg/kg PCBs; treating onsite and offsite
soil and debris with greater than 10 mg/kg PCBs
onsite using low temperature thermal
desorption, and solidifying any material that fails
the toxicity characteristic leaching procedure
(TCLP); disposing of all onsite and offsite
material contaminated with PCBs 1 mg/kg to
10 mg/kg including all treatment residuals with
less than 10 mg/kg PCBs in an onsite
containment cell with a clay and soil cover;
disposing of any material that cannot meet the
above onsite disposal criteria offsite; installing a
leachate collection and pumpout system in the
containment cell; decontaminating and
demolishing three onsite buildings, and
containing the decontaminated debris in the cell;
removing an underground storage tank and its
contents, with offsite treatment or disposal of the
contents, and onsite decontamination and offsite
disposal of the tank; excavating and treating
tank-contaminated soil; monitoring leachate and
air; and implementing institutional controls
including deed restrictions, and site access
restrictions such as fencing. The estimated
present worth cost for this remedial action is
$19,508,000. There are no O&M costs associated
with this remedial action.

CHEM-CENTRAL, Ml
September 30,1991
SITE HISTORY/DESCRIPTION:
The 2-acre Chem-Central site is a bulk chemical
storage facility in Wyoming, Kent County,
Michigan. Land use in the area is a mixture of
residential and commercial. An estimated 10,000
people live within 1 mile of the site and receive
their water supply via the municipal distribution
system. Two creeks, Cole Drain and Plaster
Creek, lie in proximity to the site. Cole Drain,
which has been included as part of the site,
empties into Plaster Creek 2,500 feet north of the
site. In addition, two hotels are located 800 feet
from the site. Since 1957, Chem-Central has
used the site to receive and hold bulk chemicals
by truck and railroad tanker before redistribution
to various industries. Facilities at the site
include a building with two loading docks and
a rail spur on the west side of the plant.
Approximately 10 above-ground storage tanks
are located along the plant's north side and are
surrounded by a concrete containment wall and
paved ground surface. Between 1957 and 1962,
hazardous substances entered the ground as a
result of faulty construction of a T-arm pipe used
to transfer liquid products from bulk storage
tanks to small delivery trucks. Additional
hazardous substances may have entered the
ground through accidental spills. In 1977, a
routine State biological survey of Plaster Creek
identified a contaminated ditch containing oils
with organic compounds including PCBs and
metals, that was discharging into Cole Drain. In
1977, the State attempted to stop the oil flow by
damming the ditch. In 1978, EPA excavated
sludge from the ditch and removed the sludge
using twelve 55-gallon drums for offsite
disposal. Oils, ground water, and various
contaminants continued to enter the ditch, and
the State unsuccessfully attempted to filter oil
out of the water. Between 1978 and 1986, the
State and EPA focused their efforts on finding
and eliminating the source of the ditch
contamination through extensive investigations
of area soil, ground water, and surface water.
Results indicated that ground water and soil
surrounding and north of the Chem-Central
plant were contaminated with volatile and
semi-volatile organic compounds. In 1980, the
State required Chem-Central to clean up the
contamination and to institute a ground water
monitoring program. Consequently, between
1984 and 1985, three ground water extraction
wells, an interceptor trench, and a treatment
system using an air stripper were installed.
Contaminated water, soil, and sludge were
removed from the ditch and placed in hazardous
waste landfills, and the ditch was backfilled with
clean soil. This ROD addresses a remedy for
contaminated onsite soil, contaminated offsite
soil surrounding and north of the plant, and the
ground water contamination plume emanating
from the plant and spreading 1,800 feet
northward. The primary contaminants of
concern affecting the soil and ground water are
VOCs including PCE, TCE, and toluene; and

collection option is used.
PERFORMANCE STANDARDS OR GOALS:
Contaminant goals for soil are based on 10"
cancer level or the Human Life Cycle Safe
Concentration (HLSC). Clean-up levels in soil
must be reduced to less than 20 times the
ground water standard for each chemical, or soil
leach tests (TCLP) must produce leachate with
contaminant levels below the ground water
clean-up levels. Chemical-specific ground water
clean-up goals are based on health-based criteria
including 10"6 risk level or Human Life-Cycle
Safe (concentration) and State levels including
TCE 3 ug/1 (health-based), PCE 0.7 ug/1
(health-based), and toluene 100 ug/1.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
installation of water wells in the site area and to
prohibit development that might disturb onsite
and some offsite soil.

CONRAIL RAILYARD ELKHART, IN
June 28,1991
SITE HISTORY/DESCRIPTION:
The 2,500-acre Conrail Railyard Elkhart site is
composed of a 675-acre railroad facility and
adjacent areas of contamination to the northeast
and northwest in Elkhart County, Indiana.
Major surface water bodies in the vicinity are the
St. Joseph River, located 1 mile north of the site,
and the Baugo Bay located to the west of the
site, which both have adjacent wetlands and
floodplain areas. From 1956 to the present, the
site has been used as a classification and
distribution point for rail freight cars. Car
repair, engine cleaning, and diesel refueling
activities were conducted onsite. Reported
onsite spills and releases of oil, diesel fuel,
hydrochloric acid, caustic soda, and various
petroleum-related substances from 1976 to 1986
have occurred onsite. EPA investigations during
the mid-1980's detected elevated levels of TCE in
ground water downgradient from the railyard,
and in the subsurface soil at various points
onsite. After initially providing bottled water,
in-house carbon filters were provided to 76
residences. This ROD provides for the
containment of the contaminated ground water
plume, as an interim action, and provides for a
safe and permanent drinking water supply. A
subsequent ROD will address contaminated soil
and ground water, and will set final ground
water remediation levels. The primary
contaminants of concern affecting the ground
water are VOCs including TCE and carbon
tetrachloride.
SELECTED REMEDIAL ACTION:
studies to determine treatment system design
parameters; providing an alternate water supply
by extending the municipal distribution system
to 505 residences/businesses; monitoring ground
water; and implementing institutional controls
including ground water use restrictions, and site
access restrictions such as fencing. The
estimated present worth cost for this remedial
action is $3,969,300, which includes an annual
O&M cost of $125,000 for 20 years.
The selected remedial action for this site includes
pumping and treatment of ground water using
prefiltration and air stripping, and discharging
the treated water onsite to the St. Joseph River;
treating air emissions, if needed, using carbon
adsorption with offsite regeneration and disposal
of the spent carbon; conducting treatability
PERFORMANCE STANDARDS OR GOALS:

DAKHUE SANITARY LANDFILL, MN
June 28,1991
SITE HISTORY/DESCRIPTION:
The 80-acre Dakhue Sanitary Landfill site is an
inactive sanitary waste municipal landfill located
in Hampton Township, Dakota County,
Minnesota. Land use in the area is agricultural
and residential. The landfill overlies a sand and
gravel surficial aquifer that is not a drinking
water source and that extends downgradient of
the site. However, 15 residential wells are
located within 1 mile of the site, and a municipal
water supply well is located over 3 miles south
of the site, all of which extract ground water
from a deeper aquifer. Investigations are
ongoing to determine whether the two aquifers
are hydraulically connected. From 1971 to 1988,
Dakhue Sanitary Landfill, Inc., owned and
operated the landfill, and accepted mixed
municipal and commercial wastes and small
amounts of industrial waste. State investigations
conducted between 1983 and 1989 identified a
variety of contaminants onsite. Investigations
during the RI/FS identified VOCs, organics, and
inorganics in the surficial onsite aquifer, and it
has been determined that the possible source of
contamination is related to the municipal,
industrial, and commercial waste disposed onsite
in the landfill. Ongoing investigations are
required to further define onsite ground water
contamination. As a result, the site will be
remediated as two operable units (OUs). This
ROD addresses the source of the contamination
as OU1. A future ROD will address ground
water contamination and possible remediation of
the downgradient plume, as OU2. The primary
contaminants of concern affecting the soil and
debris are organics including phenols; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the site with a final cover system
consisting of a gas control layer, a barrier of
low-permeability material, and a drainage layer;
revegetating the area; treating air emissions from
gas vents; conducting air and ground water
monitoring; and installing a fence around the site
perimeter. The capital cost for this remedial
action is $9,800,000, with an estimated annual
O&M cost of $54,000 for 2 years.

ENVIRO-CHEM (NORTHSIDE SANITARY LANDFILL)
(AMENDMENT), IN
June 7,1991
SITE HISTORY/DESCRIPTION:
The Enviro-Chem site is a former waste
recovery/reclamation/brokerage facility in
Boone County, Indiana. Adjacent to the site is
another Superfund site, the Northside Sanitary
Landfill (NSL) which, prior to this ROD
amendment, was to be remediated in a combined
remedy for both sites. Land use in the area is
agricultural to the south and east, and residential
to the north and west, with approximately 50
residences located within one mile of the sites.
Run-off from the sites is collected in a ditch,
which flows offsite and eventually empties into
a reservoir that provides approximately 6 percent
of the drinking water for the City of
Indianapolis. Enviro-Chem began operations in
1977 as a recovery/reclamation/brokerage
facility, accepting solvents, oils, and other wastes
from industrial clients. Accumulation of
contaminated stormwater onsite, poor
management of the drum inventory, and several
spills led to State and EPA investigations of the
site. Between 1977 and 1981, the State permitted
Enviro-Chem to dispose of part of its waste at
the adjacent NSL. In 1981, a consent decree was
issued against Enviro-Chem giving them until
November 1982 to comply with environmental
laws and regulations. In May 1982, the State
ordered Enviro-Chem to close and
environmentally secure the site because it failed
to reduce hazardous waste inventories.
Subsequently, two emergency removal actions
were conducted to remove the major sources of
contamination. From 1983 to 1984,
approximately 30,000 drums, 220,000 gallons of
waste, and 5,650 cubic yards of soil and sludge
were removed offsite and treated. In 1985,
20,000 gallons of contaminated water were
removed. A 1987 ROD provided a combined
remedy for both NSL and Enviro-Chem due to
their proximity and other similarities. The 1987
ROD addressed source control through soil
excavating, dewatering, and onsite disposal,
followed by capping; pumping and onsite
treatment of ground water; and implementing
deed and access restrictions. However, since the
signing of the ROD, EPA and the State have
been engaged in negotiating with the PRPs for
each site. These negotiations have resulted in
separate, complementary remedies and
individual consent decrees for each site, and
modifications to the original selected remedy.
This ROD amends the 1987 ROD and provides a
comprehensive site remedy for the Enviro-Chem
site addressing source control instead of ground
water remediation. The primary contaminants of
concern affecting the soil are VOCs including
PCE, TCE, toluene; and other organics including
phenols.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes treating contaminated soil onsite using
soil vapor extraction with a granulated activated
carbon system to control the extracted vapor, if
necessary; and implementing a contingent
remedy for a subsurface ground water collection
and treatment system based on monitoring
results, if clean-up objectives are not reached in
5 years. Other remedial actions documented in
the 1987 ROD including capping the site,
implementing site access restrictions, and
monitoring of the subsurface and surface water
are not affected by this amendment. The
estimated present worth for this remedial action
ranges between $5,000,000 and $9,000,000. No
O&M costs were provided for this remedial
action.

FADROWSKI DRUM DISPOSAL, Wl
June 10,1991
SITE HISTORY/DESCRIPTION:
The 20-acre Fadrowski Drum Disposal site is an
inactive industrial landfill within the city of
Franklin, Milwaukee County, Wisconsin.
Surrounding land use is mixed residential and
commercial. The western portion of the site lies
within the floodplain of the Root River, and
approximately 9 acres of wetlands are located
onsite. From 1970 until 1982 when the property
was sold, the site was an unregulated and
unlicensed landfill allowed only to receive clean
earth fill containing construction debris.
However, hazardous waste, including several
hundred drums of unknown material and
lubricant sludge, were illegally buried onsite.
State investigations in 1981 identified evidence of
improper disposal of solid wastes including
crushed drums, and boiler and foundry wastes.
In 1982, the site was purchased by Menard, Inc.,
with plans to use the property as a source of fill
material. In 1983, excavation began onsite and
during this work various containers of waste and
sludge were uncovered, some drums were
inadvertently crushed, and liquids and sludge
were released into onsite soil. The State directed
the site owners to contain the exposed waste
until it could be sampled and characterized, but
instead the owners constructed berms, then
covered the waste material with day, without
approval. The RI/FS was conducted by a PRP,
Acme Printing Ink Company. The RI located
several buried drums and identified locations
likely to contain additional buried drums.
Miscellaneous low-level soil and sediment
contamination was also delineated. Ground
water in the thick, continuous layer of clay
below the site was found to contain low levels of
cyanide, mercury, chromium, and barium. EPA
sampling has shown that nearby residential
Water supplies have not been impacted by the
contamination. This ROD addresses soil
contamination to prevent or reduce the migration
°f contaminants into the ground water. The
primary contaminants of concern affecting the
soil, sediment, and debris are VOCs including
toluene and xylenes; other organics including
PAHs and pesticides including DDT; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
excavating previously identified drums and 25
cubic yards of hazardous soil, and recycling, or
treating and disposing of the drummed waste
offsite; constructing trenches to locate and
excavate additional containerized waste and the
surrounding characteristically hazardous soil;
treating any contaminated soil onsite, followed
by offsite disposal of the residuals; constructing
a landfill cap and a leachate collection system,
and disposing of any leachate exceeding State
levels offsite at a POTW or RCRA treatment
facility; allowing natural attenuation to
remediate ground water; monitoring ground
water and surface water for 30 years to ensure
effectiveness of the cap; and implementing
institutional controls to limit land and ground
water use, and site access restrictions such as
fencing. If ground water conditions worsen or
do not improve over a reasonable period of time,
EPA may evaluate the options for a ground
water treatment program. The estimated present
worth cost for this remedial action is $2,230,000,
which includes an annual O&M cost of $32,100
for 30 years.
PERFORMANCE STANDARDS OR GOALS;
Through removal of buried drums and the
containment of remaining low-level
contamination, it is anticipated that ground
water will meet clean-up standards through
natural attenuation. Ground water clean-up
standards are based on Wisconsin Preventive
Action Limits (PALs), which are more stringent
than Federal standards.

FOLKERTSMA REFUSE, Ml
June 28,1991
SITE HISTORY/DESCRIPTION:
The 8-acre Folkertsma Refuse site is an inactive
industrial landfill in Walker, Kent County,
Michigan. Surrounding land use is primarily
industrial with a few private residences in the
vicinity. The site is partially bordered by
woodlands, and migration of contaminants has
impacted a 100-year floodplain and the scattered
wetland areas of Indian Mill Creek located to the
south. The site overlies surficial glacial and
bedrock aquifers, both of which are used for
local drinking water supplies. Onsite features
include an uncapped landfill, a man-made creek,
and a drainage ditch that join and discharge to
Indian Mill Creek; an office building; and three
warehouses. Prior to 1965, the site was used as
a muck farm. From 1965 until 1972, industrial
wastes including foundry sand, chemical
products, construction debris, and other
industrial wastes were disposed of in the onsite
landfill. The primary fill material in the landfill
is foundry sand. Since 1972, the site has been
operated as a pallet repair and manufacturing
facility. In 1984, EPA identified elevated
contaminant levels in the onsite drainage ditch
sediment, but not in onsite ground water.
Further investigations in 1985 and 1988
characterized onsite and offsite (Indian Mill
Creek) contamination, and determined the
potential for future ground water contamination.
This ROD addresses engineering controls for
source material and management of migration of
contaminated ground water, as a final remedy.
The primary contaminants of concern affecting
the landfilled material, sediment, and ground
Water are VOCs; other organics including SVOCs
and PCBs; and metals including arsenic,
chromium, and nickel.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and dewatering approximately 1,300
cubic yards of contaminated sediment from the
man-made creek, the drainage ditch, and Indian
Mill Creek, and consolidating these within the
landfill area; capping the landfill area with a clay
cap and revegetated soil cover installing passive
landfill gas vents, if necessary; converting the
man-made creek and the drainage ditch to
permeable subsurface drains to provide for
landfill surface drainage; monitoring ground
water and surface water; and implementing
institutional controls such as deed and ground
water use restrictions, as well as site access
restrictions such as fencing. The estimated
present worth cost for this remedial action is
$1,500,000, which includes an annual O&M cost
of $58,000 for the first year. O&M costs for
subsequent years were not provided.
PERFORMANCE STANDARDS OR GOALS:
The remedial action is designed to reduce the
excess lifetime cancer risk to the 10"4 to 10'6
level and the noncarcinogenic HI Ł 1.
Chemical-specific clean-up goals were not
provided.
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented at the site to prevent future
disturbances of the cap and landfill materials,
and future installation of drinking water wells.

FULTZ LANDFILL, OH
September 30,1991
SITE HISTORY/DESCRIPTION;
The 30-acre Fultz Landfill site is a privately
owned inactive sanitary landfill on the north
slope of a ridge that overlies abandoned coal
mines in Jackson Township, Guernsey County,
Ohio. Land use in the vicinity of the site is
primarily rural to the south, north, and east; and
residential and light industrial to the west. The
site lies within the drainage basin of Wills Creek,
which flows north adjacent to the site and is
used by the City of Cambridge as the municipal
water supply. The northern half of the landfill
lies in an unreclaimed strip mine where surface
mine spoil and natural soil form a shallow
aquifer. The southern half of the landfill lies
25 to 80 feet above an abandoned flooded
underground mine in the same coal seam as the
strip mine. The flooded underground mine
forms an aquifer, which also is utilized for
drinking water. Six ponds, designated as
wetlands, are located on the north side of the
landfill in the area of unreclaimed strip mine
spoil. Surface water run-off and leachate from
the landfill collect in several of these ponds.
From 1958 to 1968, the landfill was operated as
an open dump. In 1969, the site was licensed by
the County and began to accept household,
commercial, and industrial solid waste. During
the 197(ys, the landfill operator was cited for
various violations including inadequate daily
cover of waste, receiving unauthorized waste,
leachate run-off, blowing debris, and open
dumping; and in 1985, onsite landfill operations
ceased. Disposal records show that an estimated
6.240 drums containing chlorinated and
non-chlorinated solvents and plating sludge were
disposed of in the landfill. Records also show
that drummed liquid and semi-liquid wastes
were disposed of onsite, and some of the
solvents were poured directly onto the ground
frtd burned. Investigations in 1988 by EPA
indicated that ground water and leachate
contaminants emanating from the site have
contaminated the shallow aquifer and, to a lesser
extent, the deep mine aquifer. This ROD
addresses all contaminated media, and provides
a final remedy for the site. The primary
contaminants of concern affecting the soil,
sediment, debris, ground water, and surface
water are VOCs including benzene, PCE, TCE,
toluene, and xylenes; other organics including
PAHs and phenols; metals including arsenic,
chromium, and lead; and other inorganics.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing a containment berm and capping
the entire 30 acres of the landfill with a
multi-layer cap; installing structural supports for
voids in the underground mine to prevent cap
damage by subsidence; constructing an onsite
treatment plant and leachate collection system;
pumping and onsite treatment of contaminated
ground water and leachate using oxidation and
precipitation to remove metals, and filtration and
carbon adsorption to remove organics, or using
another treatment based on the outcome of a
bench-scale treatability study; discharging the
treated effluent onsite to surface water;
regenerating spent carbon or disposing of the
carbon offsite; disposing of sludge resulting from
the treatment plant processes offsite; constructing
surface water and sediment controls to divert
run-off away from the landfill; mitigating
affected wetlands; providing an alternate water
supply for contaminated residential wells by
connecting these homes to a municipal water
supply; monitoring soil, sediment, ground water,
and air; and implementing institutional controls
including deed restrictions to limit ground water
and land use, and site access restrictions
including fencing. The estimated present worth
cost for this remedial action is $19,480,700, which
includes an annual O&M cost of $218,000 for
30 years.

G&H LANDFILL, Ml
December 21,1990
SITE HISTORY/DESCRIPTION:
The 70-acre G&H Landfill site is an inactive
landfill in Shelby Township, Macomb County,
Michigan. Surrounding land use is
predominantly residential with adjacent light
industrial facilities and a recreational area that
includes wetland and woodland habitats. The
site overlies two ground water aquifers, the
uppermost of which is the source of drinking
water for some eastern area residences and
industries. A portion of the site is located within
the 100-year floodplain of the Clinton River. The
site is subdivided into three landfill areas: a
44-acre Phase I landfill area, a 17-acre Phase II
area, and an 8-acre Phase III landfill area. From
1955 to 1973, G&H landfill accepted municipal
refuse, and solid and liquid industrial wastes
including solvents, paints, varnishes, and
lacquers. In addition, from 1955 to 1967, waste
oil and water mixtures were disposed of at the
landfill. Several unsuccessful attempts were
made by the landfill operators to reclaim the oil,
by pumping the oil into settling ponds. After
the oil was allowed to settle, the volatile
components evaporated, and the resulting sludge
was periodically removed and buried in the
landfill. In 1965 and 1966, the State determined
that improper liquid waste disposal operations
and waste oil disposal/reclamation activities at
the landfill were contributing to onsite ground
water contamination and oil seeps south of the
site. Based on these findings, all disposal
operations were ordered to cease. The landfill
continued to operate as a sanitary landfill until
1973, at which time it was closed without a
proper closure plan. From 1982 to 1989, EPA
initiated four removal actions at the site to
restrict public access to contaminated ground
water and oil seeps, and to prevent the
migration of PCB-contaminated oil. In 1989,
approximately 2,400 gallons of a PCB-
contaminated oil and water mixture were
removed and disposed of at an offsite thermal
destruction facility. The site has been divided
into two operable units (OUs) for remediation.
This ROD addresses contaminated soil, sediment,
and landfill material (OU1); and the
contaminated ground water plume, landfill
leachate, and oil seep (OU2). The ground water
contaminant plume and the solvent/oil-
contaminated soil and landfill debris in the
Phase I landfill area have been identified as the
principal threat. The primary contaminants of
concern affecting the soil, sediment, debris, and
ground water are VOCs including benzene, TCE,
toluene, and xylenes; other organics including
PCBs; metals including arsenic, chromium, and
lead; and oils.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes

PERFORMANCE STANDARDS OR GOALS:
Excavated soil and sediment will be treated to
1 mg/kg to destroy PCBs if PCB concentrations
are greater than or equal to 500 mg/kg, or will
be consolidated in the landfill if PCB
concentrations are less than 500 mg/kg. Ground
water clean-up standards are based on State
standards and SDWA MCLs. Chemical-specific
goals include vinyl chloride 0.02 ug/1 (State),
benzene 1 ug/1 (State), PCE 0.7 ug/1 (State),
TCE3ug/l (State), xylenes 20 ug/1 (State),
arsenic 0.02 ug/1 (State) (may change; arsenic
standard will be established based on
background), and lead 5 ug/1 (State). NOTE:
An ESD is adjusting several ground water
standards. Existing standards less than 1 ug/1
will be adjusted to 1 ug/1 for carcinogens, which
is the approximate detection limit for chemicals
of concern. Standards less than 1 ug/1 for
inorganics will be adjusted to background levels
to be determined by EPA.
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented to supplement engineering controls
as appropriate until clean-up standards are met.

KENTWOOD LANDFILL, Ml
March 29,1991
SITE HISTORY/DESCRIPTION:
The 72-acre Kentwood Landfill site is an inactive
municipal landfill in Kentwood, Kent County,
Michigan. Land use in the area is primarily
residential and recreational. Twenty-two
residences to the south and east of the site use
ground water as their drinking water supply.
Landfilling operations at the site began in the
1950's, and continued intermittently until the
county capped and closed the landfill in 1976.
The site consists of two municipally owned
landfill areas: a larger original landfill; and a
20-acre southern extension located south-
southeast of the original landfill. Both landfills
are constructed into the uppermost aquifer
beneath the site, and as a result, the landfilled
wastes including garbage, rubbish, construction,
and demolitions wastes are in direct contact with
the upper aquifer ground water. Site disposal
records show no indication that RCRA
hazardous wastes were placed into the landfills.
In 1983, construction of a leachate collection
system to pump leachate to a POTW was
completed on the eastern side of the original
landfill; however, contamination from leachate is
still of concern. The primary contaminants of
concern affecting the debris, ground water, and
leachate are VOCs including benzene, PCE, and
TCE; other organics; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
improving the landfill cap to include gas controls
and a leachate collection system; pumping and
pretreating ground water onsite along with
collected leachate, as needed, before discharging
to a POTW; monitoring sediment, ground water,
surface water, and air; and implementing
institutional controls including deed and ground
water use restrictions, and site access restrictions
such as fencing. If for any reason the leachate or
contaminated ground water cannot be treated by
the POTW, these liquids will be treated onsite,
with subsequent onsite discharge to surface
water. The estimated present worth cost for this
remedial action is $5,700,000, which includes an
annual O&M cost of $210,000 for years 0-9, and
$200,000 for years 10-30.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific clean-up goals for ground
water in the aquifer are based on SDWA MCLs
and State standards including benzene 1 ug/1
(State), PCE 0.7 ug/1 (State), TCE 3 ug/1 (State),
arsenic 0.02 ug/1 (State), chromium 30 ug/1
(State), and lead 5 ug/1 (State).
INSTITUTIONAL CONTROLS;
Deed restrictions will be implemented to prevent
cap erosion and human exposure to site
contaminants, and to provide site security.
Ground water use restrictions will be
implemented in areas with contaminated ground
water.

SITE HISTORY/DESCRIPTION:
The 45-acre Lemberger Landfill (LL) site is a
former land disposal facility in Manitowoc
County, Wisconsin. The site is located within
one-quarter mile of another Superfund site, the
45-acre Lemberger Transport & Recycling (LTR)
site. Land use in the area is predominantly
agricultural, with four residences within 1,000
feet of the sites. Ground water, as well as the
Branch River located less than 1 mile west of
both sites, is used as a source of drinking water.
From 1940 to 1969, Franklin Township used 21
acres of the LL site as an open dump. After
1970, the State licensed the landfill to receive
only municipal waste and power plant fly ash
and bottom ash. In 1976, the LL site ceased
operations except for disposal of fly ash to bring
the site to final grade. All industrial waste was
diverted to the nearby LTR site. From 1970 to
1976, LTR received industrial waste and a variety
of liquids, sludge, and slurries, which were
deposited onsite in unlined trenches. As a result
of reports of contaminated material seeping onto
local properties, a number of State investigations
were conducted that identified VOCs levels
above State standards in residential wells.
Affected residences received deeper replacement
wells that have not shown contamination.
Because of the proximity of the sites and
similarity in the types of wastes, the the LL and
LTR sites will be remediated concurrently. This
ROD provides a final remedy for source
contamination at the LL site and ground water
contamination at both the LL and LTR sites, as
the first operable unit (OU1). A future ROD will
address the landfill contents at the LTR site, as
OU2. The primary contaminants of concern
affecting the soil, sediment, debris, and ground
water are VOCs including PCE, TCE, toluene,
and xylenes; other organics including PCBs and
Pesticides; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
clearing and regrading the waste area to smooth
out the existing cap; constructing a multi-layer
cap with a vegetative cover to minimize cap
erosion; constructing a slurry wall around the
perimeter of the wastes; installing at least one
small volume extraction well in the upper
aquifer to collect ground water within the slurry
wall; building an onsite treatment facility at the
LL site, and treating contaminated ground water
from both sites using electrochemical
precipitation to remove inorganic contaminants
and granular activated carbon to remove organic
contaminants, unless trea lability studies deem
another technology to be more effective;
blending water extracted from the slurry wall
with ground water extracted for remediation,
and treating these at the treatment facility;
temporarily storing the residual sludge onsite in
55-gallon drums, followed by disposing of
residual sludge as part of the future LTR source
control remedy or treating and disposing the
sludge offsite at a RCRA landfill according to
Federal and State regulations; recycling spent
carbon, if possible; discharging the treated
effluent onsite to the Branch River; providing an
alternate water supply to residents whose water
supply is disrupted due to the operation of the
extraction system; investigating and mitigating
any affected wetlands; monitoring ground water;
possibly implementing institutional controls
including deed and ground water use
restrictions; and constructing a security fence
around the treatment facility to limit site access.
The estimated present worth cost for this
remedial action is $19,200,000, which includes an
annual O&M cost of $731,000 for years 0-1 and
$596,000 for years 2-30.

MacGILLIS & GIBBS/BELL LUMBER & POLE, MN
September 30,1991
SITE HISTORY/DESCRIPTION:
The MacGillis & Gibbs/Bell Lumber & Pole site
consists of two active, adjacent wood preserving
facilities, referred to as the M&G and Bell
facilities, in New Brighton, Ramsey County,
Minnesota. Land use in the area is residential
and commercial. Several lakes, streams, and
wetlands are located within 2 miles of the site.
Most local residents receive drinking water from
10 municipal wells, the nearest of which is
located one-quarter mile southeast of the site.
There are also a limited number of residential
wells existing in the area. This ROD addresses
the 24-acre M&G facility on the eastern portion
of the site. Site features include a disposal area
in the west-central portion of the facility used to
dispose of PCP-contaminated wood chips, settled
solids, spent treatment solutions, and copper
chromium arsenic (CCA) contaminated drum
shells; onsite drums; and a storage area. From
the late 1920's to 1970, M&G used the site to
treat wood poles with various preservatives
including creosote and PCP. Process wastewater
from these activities may have been discharged
to the disposal pond. In 1970, M&G began using
only CCA for treatment and began recycling the
process solution within the treatment system.
Investigations conducted by EPA have detected
contamination of the onsite surface and
subsurface soil and ground water, which is
thought to be a result of leaking pipes, drippings
from treated poles, contamination from the
disposal area, and an onsite spill of 4,000 to 5,000
gallons of CCA in 1979. In 1988, M&G
conducted initial clean-up activities by
overpacking and storing onsite approximately
200 deteriorated drums containing PCP-
contaminated soil and waste. In 1989, a thick
layer of PCP-contaminated oil, referred to as the
LNAPL plume, was identified floating on the
upper aquifer. Subsequently, a pump was
installed in an onsite well to recover the oil,
which is currently stored onsite in the drum
storage facility. In 1988, EPA initiated pilot tests
for soil washing to remove PCP and PAHs from
contaminated onsite soil, and in 1989 initiated
tests for a mobile biological ground water
treatment system. EPA has divided the site into
two operable units (OUs) for remediation. OU1
will address remediation within the onsite
disposal area of the M&G facility. OU2 will
address ground water remediation for the entire
site, as well as remediation of soil, process and
storage tanks, and waste containers outside of
the disposal area. This ROD provides an interim
remedy for OU2. The primary contaminants of
concern affecting the soil, debris, sludge, and
ground water are organics including dioxins,
PAHs, and PCP; and metals including arsenic
and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
removing 100,000 gallons of PCP waste oil and
sludge from abandoned, above-ground and
underground PCP process/storage tanks;
decontaminating, dismantling, and disposing of
offsite the waste process/storage tanks;
separating PCP wastes and decontamination
liquids into oil and water phases using an
oil/water separator; plugging a discharge line
from one of the underground vaults to the
disposal offsite area; pumping ground water
from beneath the LNAPL plume to enhance
LNAPL recovery via a ground water
depression/oil extraction process; containing and
onsite storage of PCP-contaminated oil and
sludge from tanks, residuals from ground
water/wastewater treatment facility, and LNAPL
oil from ground water; treating ground water,
and tank and tank decontamination wastewaters
using an onsite bioremediation wastewater
treatment facility and, if necessary, a carbon
adsorption polishing unit; discharging effluent

MAIN STREET WELL FIELD, IN
March 29,1991
SITE HISTORY/DESCRIPTION:
The 48-acre Main Street WeH Field (MSWF) site
is in Elkhart, Elkhart County, Indiana. The well
field provides the primary water supply for the
44,000 city residents. Adjacent to the site are
several industrial properties, Excel and Durakool
to the east; Elkhart Products to the west that
used TCE and other organic solvents as part of
their operations. The site is bounded by
Christiana Creek to the north and the St. Joseph
River to the south. MSWF is located in both a
wetlands and a floodplain, and overlies a sole
source aquifer. Since the early 1900's, an onsite
treatment and pumping station has been used
for the purification and distribution of water to
the surrounding community. The well field
contains 17 production wells, two interceptors
used as production wells, two 2-million gallon
storage tanks, an air stripper facility, and
recharge ponds. Site contamination first
occurred during the 1950's when phenols from a
nearby fuel tank farm, east of the well field,
were detected in onsite wells. The
contamination was mitigated by excavating six
recharge ponds and diverting the water to those
ponds from Christiana Creek. During routine
sampling in 1981, EPA identified TCE
contamination in onsite wells. Sampling wells
were installed on the Excel and Durakool
properties, and the results of this testing
indicated these industries were the likely sources
of contamination. Subsequently in 1981, the city
constructed two eastern interceptor wells, which
discharged to Christiana Creek, and removed the
nearby production wells from service. As a
result, TCE levels in finishing and production
wells dropped significantly. In 1984, TCE levels
on the west side of the field increased, and EPA
suspected a second plume had impacted the well
field. A 1985 ROD provided for construction of
an air stripping facility to treat water from the
seven production wells and the two eastsidc
interceptions. Subsequent investigations further
characterized onsite contamination and led to the
discovery of a TCE-contaminated paint layer on
the soil in eastern area of the site. This ROD
addresses management of migration of the
western contaminant plume, as well as source
control on the east side of the well field. A third
remedial action may be necessary if further
onsite contamination is identified. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE, TCE,
and xylenes; other organics including PAHs; and
metals including arsenic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating 22,000 cubic feet of contaminated soil by
in-situ vacuum extraction; removing 60 cubic
yards of soil containing the paint layer, followed
by offsite incineration or suitable treatment
based on waste characterization and offsite
disposal in accordance with the Land Disposal
Restrictions Soil and Debris Treatability
Variance; constructing new interceptor wells on
the west side of the field; continued pumping
and treatment of ground water using the existing
air stripping unit; monitoring ground water; and
implementing institutional controls including
deed restrictions. The estimated present worth
cost for this remedial action is $3,370,000, which
includes an estimated annual O&M cost of
$130,000 for 20 years.
PERFORMANCE STANDARDS OR GOALS:
Performance standards for soil and ground water
are based on a 10"5 excess lifetime cancer risk.
Chemical-specific goals for soil include TCE
100 ug/kg. Interceptor wells will remain
operational as long as plumes entering the field
have cancer risk levels greater than 10".
Chemical-specific goals for ground water include
PCE 0.6 ug/1 and TCE 1 ug/1.

MICHIGAN DISPOSAL SERVICE, Mi
September 30,1991
SITE HISTORY/DESCRIPTION:
The 68-acre Michigan Disposal Service Landfill
site is an inactive municipal landfill in
Kalamazoo, Kalamazoo County, Michigan. Land
use in the area is predominantly industrial,
commercial, and residential. The eastern border
of the site lies within a wetland and the 100-year
floodplain of nearby Davis Creek. From 1925 to
1961, the site was owned and operated by
private parties as a municipal landfill.
Forty-seven acres of the total site were used as a
landfill. In 1961, the City of Kalamazoo
purchased the property and began accepting
wastes from residences, businesses, and local
industries. The majority of these wastes were
incinerated onsite, with onsite disposal of the
ash. From 1968 to 1981, the site was licensed to
accept only inert wastes, and incineration ceased
due to new air pollution regulations. In 1981,
the site was sold, and subsequently, was
operated as a licensed landfill. During the
mid-1980's, the State conducted investigations as
part of a landfill extension request These onsite
studies documented that wastes leaching from
the landfill had contaminated onsite soil,
sediment, and ground water. To continue
landfill operations, the owners were ordered to
install a collection system to intercept leachate
prior to entry into Davis Creek to prevent
contamination of the creek. This ROD addresses
onsite contaminated soil, sediment, ground
water, and surface water, as a final remedy. The
primary contaminants of concern affecting the
soil, sediment, debris, ground water, and surface
water are VOCs including benzene; other
organics including PCBs; and metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing a clay cap and revegetating the landfill
contents; installing a leachate collection system
and a gas venting system for the landfill;
pumping and pretreating ground water onsite, as
required, followed by offsite discharge of the
ground water/leachate to a POTW; monitoring
all media; and implementing institutional
controls, and site access restrictions including
fencing. The estimated present worth cost for
this remedial action is $8,269,500, which includes
an annual O&M of $253,800 for 20 years.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals are based on
SDWA and State standards. Chemical-specific
goals for ground water include benzene 1 ug/l
(State), arsenic 0.02 ug/l (State), and lead 5 ug/l
(State).
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented to prevent exposure to site
contaminants.

MOTOR WHEEL, Ml
September 30,1991
SITE HISTORY/DESCRIPTION:
The 24-acre Motor Wheel site is an inactive
industrial waste disposal site in Lansing, Ingham
County, Michigan. Land use in the area is
predominantly industrial. The site overlies a
glacial till and a glacial aquifer. From 1938 to
1978, the Motor Wheel Corporation used the site
for the disposal of solid and liquid industrial
wastes including paints, solvents, liquid acids
and caustics, and sludge. Wastes were disposed
of in tanks, barrels, seepage ponds, and open fill
operations. An estimated 210,000 cubic yards of
waste fill are in place onsite. As a result of
disposal practices, contaminants have leached
through the soil and into the underlying glacial
aquifer and perched zone. Between 1970 and
1982, at least three onsite clean-up actions were
initiated. In 1970, the State required the removal
and offsite disposal of solid wastes, paint sludge,
and oils from seepage ponds and backfilling of
excavated pond areas. In 1978, industrial wastes
and degraded soil were excavated and stockpiled
onsite under a clay cover. In 1982, the site
owners removed three 10,000-gallon tanks, their
contents, and surrounding contaminated soil,
along with contaminated fill material containing
an unknown quantity of drums. This ROD
addresses the waste mass and ground water
contamination in the perched zone and the
glacial aquifer. The primary contaminants of
concern affecting the soil, debris, and ground
water are VOCs including benzene, PCE, TCE,
toluene, and xylenes; other organics including
PAHs, PCBs, and pesticides; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
backfilling the northern portion of the fill area
with 125,000 cubic yards of fill; capping the
disposal area with a 14.9-acre multi-media cap;
installing a slurry wall at the western and
southern boundary of the disposal area;
installing ground water recovery wells or
trenches downgradient, and a collection transfer
system to deliver water to an onsite treatment
facility; pretreating ground water onsite to
remove iron and manganese using aeration,
clarification, and filtration if needed, followed by
onsite treatment using air stripping and carbon
adsorption; using activated alumina to remove
fluoride from ground water, followed by offsite
discharge of the treated water to a POTW;
monitoring ground water; and implementing
institutional controls including deed and ground
water use restrictions, and site access restrictions
such as fencing. The estimated present worth
cost for this remedial action is $30,720,300, which
includes a capital cost of $11,083300 and an
annual O&M cost of $1,277,400 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals are based on State
health-based standards or method detection
limits (MDL), whichever is higher. Chemical-
specific goals include benzene 1 ug/1 (State),
PCE 1 ug/1 (MDL), TCE 3 ug/1 (State), toluene
800 ug/1 (State), xylenes 300 ug/1 (State), and
lead 5 ug/1 (State).
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented onsite.

NATIONAL PRESTO INDUSTRIES, Wl
September 30,1991
SITE HISTORY/DESCRIPTION:
The 325-acre National Presto Industries site is a
former munitions and metal-working facility in
Eau Claire, Chippewa County, Wisconsin,
adjacent to the town of Hallie. Surrounding land
use is light residential and commercial, and the
Chippewa River is located approximately 2 miles
north and west of the site. Lake Hallie is located
approximately 1 mile north of the site. The site
overlies a buried pre-glacial valley that serves as
a primary source of drinking water. From 1942
until 1945, the site was a government-owned,
contractor-operated producer of gunpowder,
small arms, and radar tubes. The site was
owned by National Presto Industries (NPI) since
1948. Initially, NPI manufactured cookware and
consumer products, and generated waste streams
consisting of metals, oils, grease, and spent
solvents during operations. Also, beginning in
1951, artillery shell fuses and aircraft parts were
produced by NPI under military contracts.
Metal projectiles production began in 1954 under
separate contracts. Early waste-handling
practices included the use of dry wells and
seepage pits with overflow from the pits
discharged to a former sand and gravel pit via
gravity flow. Wastes also were discharged
directly to the sand and gravel pit. During the
1960's, three additional lagoons were constructed
as percolation ponds with the former sand and
gravel pit serving as a settling pond. A major
waste stream generated from the defense-related
activities was a spent forge compound,
composed of mineral oil, graphite, VOCs, and
asphalt, which accounts for much of the sludge
in the bottom of one of the settling ponds. From
1966 to 1969, the spent forge compound also was
landfilled onsite. Subsequently, the spent forge
compound was recycled as part of the
manufacturing process. Based on their
investigations, EPA required NPI to provide
bottled water to an area in Hallie where private
wells were contaminated or threatened by
contamination from confirmed onsite sources. A
1990 ROD provided a permanent alternate water
supply in the form of hookups of affected
residents and businesses to municipal
distribution systems. Further investigations by
EPA helped determine the presence of four
major contaminants migrating from the NPI site.
This ROD addresses management of migration
as an interim remedy. A subsequent ROD will
address final remedies for both onsite source
control and ground water. The primary
contaminants of concern affecting the ground
water are VOCs including PCE, TCA, and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes onsite pumping and treatment
of ground water using two cascade aeration
units; discharging the treated water to onsite
storm sewers for transport to surface water;
conducting further studies to determine the need
for pretreatment of ground water; installing a
dedicated pipe system for surface water
discharge if the storm sewer system cannot be
utilized; and conducting long-term ground water
monitoring. The estimated present worth cost
for this remedial action is $1,290,000, which
includes an annual O&M cost of $163,000 for
years 0-1 and $104,000 for years 2-30,
PERFORMANCE STANDARDS OR GOALS:
Treated water must meet the requirements of
CWA Ambient Water Quality Criteria and State
standards for discharge to surface water.
Chemical-specific goals are not provided, but
will be developed as part of subsequent
investigations.

NORTHSIDE SANITARY LANDFILL (ENVIRO-CHEM)
(AMENDMENT), IN
July 31,1991
SITE HISTORY/DESCRIPTION:
The Northside Sanitary Landfill site is a
hazardous and solid waste disposal facility in
Boone County, Indiana. Adjacent to the
Northside Sanitary Landfill (NSL) site is another
Superfund site, Enviro-Chem which, prior to this
ROD amendment, was to be remediated in a
combined remedy for both sites. Land use in the
area is agricultural to the south and east, and
residential to the north and west, with
approximately 50 residences located within one
mile of the sites. Run-off from the sites is
collected in a ditch, which flows offsite and
eventually empties into a reservoir that supplies
approximately 6 percent of the drinking water
for the City of Indianapolis. NSL began
operating as a landfill between 1955 and 1962.
By 1981, NSL was operating as a hazardous
waste disposal facility and had accepted at least
16 million gallons of hazardous substances
including paint sludge, acids, spent acids, and
waste oil. Throughout its operation history, NSL
was allegedly accepting an abundance of
unapproved waste from offsite facilities
including Enviro-Chem, an adjacent waste
recovery, reclamation and brokering facility.
Additionally, EPA and the State cited NSL for
numerous operational deficiencies. In 1983,
NSL's hazardous waste and solid waste
operators permits were denied because of
leachate collection problems, acceptance of
unapproved waste, and deficiencies in its
closure, post-closure, and ground water
assessment plans. The State then ordered NSL
to perform several remedial measures including
installing a functioning leachate collection system
around the entire perimeter of the landfill,
installing a slurry wall or another measure to
prevent ground water migration, monitoring
ground water, and to discontinue acceptance of
solid waste except for that amount needed to
adequately contour the site. A 1987 ROD
provided a combined remedy for both the NSL
and Enviro-Chem sites due to their proximity
and other similarities. The 1987 ROD addressed
source control capping; pumping and onsite
treatment of ground water; and implementing
deed and access restrictions. Since the signing of
the ROD, EPA and the State have been engaged
in negotiations with the PRPs for each site.
These negotiations have resulted in separate,
complimentary remedies and individual consent
decrees for each site, and modifications to the
original selected remedy. This ROD amendment
provides a comprehensive remedy and addresses
both source control and ground water
remediation. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, PCE, TCE, and toluene; other
organics including phenols; metals including
arsenic, chromium, and lead; and oils.
SELECTED REMEDIAL ACTION:
The selected amended remedial action for this
site includes constructing a pipeline to pump
ground water and leachate offsite to the city
sewer system at the city wastewater treatment
plant and constructing a hydraulic isolation wall
system south and west of NSL to prevent
uncontaminated ground water from entering the
ground water leachate collection trench. If for
any reason the city treatment plant cannot be
used, this ROD amendment provides a
contingency for onsite treatment of ground
water, followed by onsite discharge to surface
water as specified in the 1987 ROD; treatment at
another wastewater treatment plant; or another
alternative consistent with the Clean Water Act.
Other remedial actions documented in the 1987
ROD including construe ting a RCRA cap and gas
venting system; collecting leachate and ground
water in a trench system; monitoring ground
water, surface water, and leachate; and
implementing site access restrictions are not
affected by this amendment. The estimated
present worth cost for this remedial action

NOVACO INDUSTRIES (AMENDMENT), Ml
September 5,1991
SITE HISTORY/DESCRIPTION:
The 2.6-acre Novaco Industries site is a one-
building site in Temperance, Michigan. Land
use in the area is predominantly residential and
agricultural. The estimated 85 residences located
within 1/2 mile of the site use the underlying
sand/gravel and limestone aquifer as their
drinking water supply. In 1979, a chromic acid
leak occurred from a 1,870-gallon underground
storage tank at Novaco, which led to chromium
contamination of an onsite well. Subsequent
sampling from 1979 to 1982 detected chromium
in wells of properties adjacent to the site, and as
a result, new wells were installed in the
uncontaminated lower aquifer. Later in 1979,
Novaco Industries began pumping and treatment
of 122,000 gallons of contaminated ground water,
removing 400 pounds of hexavalent chromium.
In 1983, the State sampled several residential
wells, and chromium was not detected above
background levels. However, sampling of
ground water monitoring wells in 1984 and 1985
revealed chromium contamination levels in
excess of the MCL. A 1986 ROD addressed a
final remedy for ground water contamination,
and provided for ground water pumping and
treatment using electrochemical reduction/ion
exchange polishing, followed by onsite discharge
to surface water. This ROD amends the 1986
ROD. Pre-design studies during 1988 have
determined that contaminant levels have
continued to decrease over time, and there is no
longer any indication of a chromium
contaminant plume. Therefore, based on these
data, there are no contaminants of concern
affecting the site.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site is no
further action. Although no significant
contamination is present at the site, EPA
recommends that nested wells be installed and
ground water monitoring be implemented to
evaluate the attenuation process. However, if
contaminant levels for hexavalent chromium
exceed 50 ug/1 for two consecutive periods of
monitoring, the remedy from the 1986 ROD will
be implemented. There are no costs associated
with this no action remedy.

OAK GROVE SANITARY LANDFILL, MN
December 21,1990
SITE HISTORY/DESCRIPTION:
The 45-acre Oak Grove Sanitary Landfill is a
former municipal and industrial solid waste
landfill in Oak Grove Township, Anoka County,
Minnesota. Land consists of low regions of
uplands and sand dunes interspersed among
numerous lakes and wetlands. The nearby
developed land use in the area is agricultural
and residential. The site overlies two aquifers,
which are separated by a semi-confining layer.
The deeper aquifer provides regional potable
water and supplies many area residential wells.
Landfill operations began in 1967 and continued
until 1984, when the operating license was
suspended. An estimated 2.5 million cubic yards
of waste is present in the landfill including
acidic oil sludge, paint and solvent waste,
foundry sands and sludge, inorganic acids, metal
sludge, and chlorinated and unchlorinated
organic compounds from pesticide
manufacturing. In addition, lime sludge was
used as a cover material on two-thirds of the
landfill. A 1988 ROD addressed the sources of
contamination by containing the onsite waste
and contaminated soil with a cover. EPA
investigations in 1989 determined that the
contaminated shallow aquifer discharges directly
to the surface water of the adjoining wetlands
where ground water contamination is being
reduced by natural attenuation, and thus, limits
migration of contaminants to the surface water.
This ROD addresses remediation of
contaminated shallow ground water, prevention
of significant impacts on surface water from the
discharge of contaminated shallow ground
water, and provides for continued use of the
deep aquifer as a drinking water supply. The
primary contaminants of concern affecting the
ground water are VOCs including benzene,
toluene, and xylenes; and metals including
arsenic.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
long term monitoring of the shallow and deep
aquifers, surface water, and sediment at a
frequency of three times per year for the first
year and semi-annually thereafter; natural
attenuation of shallow ground water;
abandoning non-essential wells; and
implementing institutional controls including
ground water use restrictions. The estimated
present worth cost for this remedial action is
$800,000, which includes an annual O&M cost of
$90,000 for the first year and $70,000 for
subsequent years.
PERFORMANCE STANDARDS OR GOALS:
Sediment, ground water, and surface water
monitoring will assure that contaminant levels
do not exceed SDWA MCLs, CWA AWQCs, and
State surface water quality standards.
INSTITUTIONAL CONTROLS:
Institutional controls will be implemented for the
placement of drinking water wells.

SITE HISTORY/DESCRIPTION:
The 5-acre Organic Chemicals site is an inactive
solvent reclamation and chemicals manufacturing
facility in Grandville, Kent County, Michigan.
The site includes several onsite buildings,
structures, above-ground storage tanks, and
drum storage areas, a boiler facility, a
wastewater treatment facility, and a seepage
lagoon. Wetlands potentially are located 1,900
feet northwest of the site, and the Grand River is
located 0.95 miles to the north of the site. A
succession of petroleum-related industries leased
the land for petroleum refining from 1941 to
1945, followed by transport and storage
operations from 1945 to 1966. Organic
Chemicals Inc. (OCI), began site operations in
1968. Company records show that between 1968
and 1980, process waste and cooling water
including RCRA hazardous wastes were
discharged to the onsite seepage lagoon. In
1979, 2,200 gallons of lacquer thinner were
spilled onto the ground onsite and, subsequently,
some of the spilled thinner was recovered and
disposed of onsite in the seepage lagoon. In
1980, discharges to the lagoon ceased, and the
company installed a wastewater pretreatment
system, which discharged wastes to the sanitary
sewer system. Subsequently, in 1981, the
seepage lagoon sludge was excavated and
disposed of offsite. In 1983, EPA documented
onsite soil and potential ground water
contamination resulting from the solvent-
contaminated seepage lagoon. Additionally, in
1986, the State determined that OCI was illegally
disposing of sludge and other hazardous
residuals from the onsite solvent recovery
operations by placing these into drums or rolloff
containers along with routine non-hazardous
waste materials. Analysis of the drum and
container contents and soil samples from the
vicinity of these storage units revealed the
presence of VOCs and other organics.
During 1987, OCI, as part of a voluntary
investigation, discovered and removed 150
buried drums containing sludge and liquid
residues offsite, and identified further onsite soil
contamination. Federal and State investigations
have determined that site contamination has
resulted from past operation of the seepage
lagoon by OCI, chemical spills at the site and
past oil-related activities. EPA has divided the
remediation into two response actions. This
ROD addresses contamination in the upper
ground water system, as an interim remedy. A
future ROD will constitute the final response at
the site by addressing the remaining onsite
ground water and soil contamination. The
primary contaminants of concern affecting the
ground water are VOCs including benzene,
toluene, and xylenes; and other organics
including PAHs and pesticides.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
onsite pumping and treatment of ground water
using a treatment system consisting of an
equalization/sedimentation basin, two granular
activated carbon vessels, and an air stripper
polishing unit; discharging the treated water
onsite to the Grand River; disposing of treatment
carbon residuals in an offsite landfill; conducting
a treatability study and pump test to determine
the proper treatment train and pumping rates;
and ground water monitoring. The estimated
present worth cost for this interim remedial
action is $5,931,000, which includes an annual
O&M cost of $317,000.
PERFORMANCE STANDARDS OR GOALS:
This remedial action is only part of a total
remedial action and will attain ground water
clean-up ARARs during future response actions.

OSSINEKE GROUND WATER CONTAMINATION, Ml
June 28,1991
SITE HISTORY/DESCRIPTION:
The Ossineke Ground Water Contamination site
is an area overlying a contaminated aquifer in
Ossineke, Alpena County, Michigan. Land use
in the area is predominantly residential and
commercial, with wetlands areas bordering the
west and northeast boundaries of the site. The
site hydrogeology is characterized by an upper
aquifer and lower confined aquifer, both of
which supply drinking water to local residents.
Historically, there have been two contaminant
source areas of concern within Ossineke. Area 1
is in the center of the Town of Ossineke where
two gas stations are located, consisting of
underground storage tanks, and a former
automobile rustproofing shop. In 1973, the
rustproofing shop closed, the garage floor was
reportedly washed with chlorinated solvents,
and the residue was disposed of on the ground
behind the shop. Area 2 is a laundry and dry
cleaning facility that has an associated wash
water pond containing chlorinated hydrocarbons
and VOCs. In 1977, citizen complaints about
odors from drinking water obtained from the
upper aquifer prompted a number of State
investigations, which revealed extensive onsite
ground water contamination in the upper
aquifer. Consequently, the State advised all
users of the upper aquifer to stop using their
wells. In 1982, the State discovered that a snow
plow had hit a gasoline pump causing an
unknown amount of gasoline to spill and,
subsequently, contaminate the basements of
several businesses. In 1986, the State replaced
the residential wells affected by ground water
contamination. Because the contaminants of
concern have been confirmed to be related to
petroleum releases from underground storage
tanks, the Superfund program does not have the
authority to address cleanup under CERCLA.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site is that
no further action be taken under CERCLA
Section 101, and that the site be transferred to
the EPA Office of Underground Storage Tanks
(OUST). In 1990, a formal transfer of the project
from OSWER to OUST occurred. There are no

PAGEL'S PIT, IL
June 28,1991
SITE HISTORY/DESCRIPTION:
The 100-acre Pagel's Pit site is an active sanitary
landfill facility in a predominantly rural area of
Winnebago County, Illinois. Surrounding land
use is mixed agricultural, rural residential,
commercial, and industrial. The site is bounded
on the west by Killbuck Creek. Another
Superfund site, Acme Solvent Reclaiming, Inc., is
located east and upgradient of Pagel's Pit. The
Acme Solvent site has been shown to have
contaminated the ground water in the
downgradient direction. The landfill at the
Pagel's Pit site is a former sand and gravel
quarry with a sealed asphalt liner that covers
about 47 acres. The landfill, which began
operating in 1972, accepted primarily municipal
waste, sewage sludge, and limited amounts of
Illinois special wastes. Beginning in 1980, a
network of gas extraction wells was installed to
remove landfill gas that is generated by the
wastes. Gas collected from the wells is used as
a fuel source for a sludge drying operation.
Some of these wells also are used for leachate
collection along with the manholes installed in
the landfill. In 1990, it was estimated that the
landfill contained about 4,700,000 cubic yards of
waste and had 5 to 7 years of operating capacity
remaining. It has been determined that the
landfill has caused contamination of the ground
water. This ROD addresses the landfill wastes
and contaminated ground water at the
downgradient side of the site as operable unit 1
(OU1). A future ROD will address ground water
contamination in the southeast corner of the site
that is currently undergoing further study. The
primary contaminants of concern affecting the
ground water are VOCs including 1,2-
dichloroethene and vinyl chloride; and metals
including arsenic, barium, manganese, thallium
and zinc.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing a sanitary landfill cover for the
waste disposal area; pumping ground water
along the west side of the site; removing
inorganics by treating with ion exchange or
coagulation/flocculation, if necessary, prior to
onsite treatment using carbon adsorption or air
stripping, followed by carbon polishing of the
treated water, with onsite discharge to surface
water; removing spent carbon offsite for
regeneration or disposal; extracting and treating
leachate offsite at a POTW; extracting landfill gas
and using the gas for fuel, or flaring the gas;
monitoring ground water, leachate, and air;
maintaining all remedial action components; and
implementing institutional controls including
deed restrictions. The estimated present worth
cost for this remedial action is $9,800,000 or
$11,000,000, which includes O&M costs of
$310,000 or $248,000 for 30 years, depending on
the process selected.
PERFORMANCE STANDARDS OR GOALS:
Ground water goals are based on currently
promulgated MCLs or non-zero MCLGs, (except
for arsenic and 1,1,-dichloroethene) or a risk
level of 10"5 or an HI=1 for contaminants without
MCLs. Chemical-specific goals were not
provided.
INSTITUTIONAL CONTROLS:
Deed restrictions may be implemented to limit
the development of property, and the placement
of new wells on the property and adjacent to the
site.

PINE BEND SANITARY LANDFILL, MN
September 30,1991
SITE HISTORY/DESCRIPTION:
The Pine Bend Sanitary Landfill site is located
1 mile east of the Mississippi River in Inver
Grove Heights, Dakota County, Minnesota.
Land use in the area is residential and industrial.
The terrain is generally flat and contains an
immature drainage system resulting in onsite
numerous ponds and wetlands. The site is
composed of two landfills: the 255-acre active
Pine Bend Sanitary Landfill (PBSL) and the
inactive 52-acre Crosby American Demolition
Landfill (CADL). PBSL began operation in 1971
as a mixed municipal solid waste facility, CADL
accepted compressed bales of municipal solid
wastes from 1971 to 1974, and later, from 1976 to
1989 also accepted demolition wastes.
Hydrogeologic data from the site show that the
two landfills are considered one site because
their ground water plumes commingle within a
common surficial aquifer. The resulting plume
moves through the surficial aquifer and is
believed to eventually discharge to the
Mississippi River via springs in the river bottom.
In 1983, elevated levels of VOCs were detected
in the surficial ground water beneath the site,
and low levels of VOCs were identified in
numerous downgradient commercial and
residential wells. This contamination is believed
to be the result of precipitation infiltrating
through the permeable landfill material and
coming in contact with buried waste. Since 1986,
at the request of the State, CADL has provided
bottled water to residences with contaminated
wells to minimize the risk of VOC-contamination
migrating from the PBSL/CADL site. This ROD
addresses ground water contamination as the
first of three operable units (OUs). Future RODs
will address source control and final remediation
of ground water. The primary contaminants of
concern affecting the site are VOCs including
benzene, PCE, TCE, and toluene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
providing a permanent alternative water supply
by extending the existing Inver Grove Heights
municipal water supply; connecting impacted or
potentially impacted premises to the municipal
water supply; and permanently sealing the
potentially affected onsite private water supply
wells. The estimated present worth cost for this
remedial action is $2,649,499, which includes an
annual O&M cost of $30,350 for 30 years.

RASMUSSEN'S DUMP, Ml
March 28,1991
SITE HISTORY/DESCRIPTION:
The 33-acre Rasmussen's Dump site is a former
industrial and domestic waste disposal area in
Green Oak Township, Livingston County,
Michigan. Surrounding land is predominantly
wooded with some residential and agricultural
development. Area residents rely solely on the
aquifer underlying the site for their drinking
water supply. The site is adjacent to the
Spiegelberg Landfill, another Superfund site.
During the 1960's and early 1970's, domestic,
industrial, and drummed hazardous wastes were
disposed of on approximately one-third of the
site. Many incidences of onsite burning of
wastes were reported during operational years of
the facility. Landfill operations ended in 1977
without complying with State laws on proper
capping or closure. Sand and gravel mining,
which began following site closure, caused
unearthed waste fill and drummed wastes to be
redistributed around the site. In 1981, the State
detected low levels of ground water
contamination onsite. This contamination
includes: two onsite contaminated ground water
plumes and four areas of soil contamination
referred to as the Top of the Municipal Landfill
(TML), the Northeast Buried Drum Area
(NEBD), the Industrial Waste Area (IW), and the
Probable Drum Storage, Leakage, Disposal Area
(PDSLD). In 1984, EPA removed approximately
3,000 drums and 250 cubic yards of
contaminated onsite soil. In 1990, the PRPs
removed an additional 650 onsite drums, waste,
and associated visibly contaminated soil from the
TML, NEBD, and IW areas, thereby reducing the
risk posed by the areas. Testing in the PDSLD
area indicated that soil contamination resulting
from drum leakage continues to migrate into the
soil directly above the ground water table or into
the ground water itself, and poses a continuing
ground water threat. This ROD provides a final
remedy for onsite contaminated soil and ground
Water. The primary contaminants of concern
affecting the soil and ground water are VOCs
including benzene, TCE, toluene, and xylenes;
other organics including ketones, chlorinated
hydrocarbons, and phenols; and metals including
cadmium, and lead,
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the waste in the TML and NEBD areas,
and removing and disposing of waste drums
unearthed during cap construction offsite at a
RCRA facility; ground water pumping and
treatment using chemical precipitation followed
by pH adjustment to remove metal
contaminants, a biological treatment system to
remove organic ground water contaminants, and
air stripping and granular activated carbon to
remove residual organic contaminants as
necessary; discharging the treated ground water
onsite through a seepage basin in the IW and
PDSLD areas to flush area soil; monitoring
ground water; continuing residential well
sampling in conjunction with sampling for the
adjacent Spiegelberg Superfund site; and
implementing institutional controls including
deed restrictions, and site access restrictions such
as fencing. The estimated capital cost for this
remedial action is $7,320,000, with an annual
O&M cost of $4,580,000.
PERFORMANCE STANDARDS OR GOALS:
Soil contaminant levels in the PDSLD/IW areas
will be reduced to less than 20 times the ground
water clean-up level for each chemical; or leach
tests performed on the PDSLD/IW soil must
produce leachate with concentrations below the
ground water clean-up levels. Ground water
clean-up goals are based on a 10"6 cancer risk
level, Human Life Cycle Safe Concentrations
(HLSC) detection limits, Taste and Odor (T&O)
Threshold, State standards, and risk- and
health-based criteria. Chemical-specific goals for

SOUTHEAST ROCKFORD GROUNDWATER CONTAMINATION, IL
June 14,1991
SITE HISTORY/DESCRIPTION:
The 2- to 3-square mile Southeast Rockford
Groundwater Contamination site is a residential
area with contaminated private wells in
Winnebago County, Rockford, Illinois. The site
is in a predominantly urban residential area that
includes retail and commercial operations.
Surrounding land use is industrial. During
sampling from 1981 to 1984, the City of Rockford
identified elevated VOC levels in ground water.
Subsequently, in 1985, four municipal wells
including Municipal Well #35 and several private
wells were closed. In 1984, after plating waste
was illegally disposed of in a well, EPA
conducted investigations that identified
contamination by VOCs and inorganics in
municipal and private wells. From 1986 to 1989,
further EPA investigations defined a 1.2-mile
contaminated area. In 1989, EPA initiated an
emergency action including temporarily
providing bottled water and attaching carbon
filters at affected residences and ultimately
connecting wells to the city water supply if VOC
contamination exceeded 25 percent of the
Removal Action Level (RAL). This ROD
addresses the elimination of risk to residents of
the Southeast Rockford area due to contaminated
ground water. A subsequent ROD will address
remediation of the contaminated ground water
plume. The primary contaminants of concern
affecting the ground water are VOCs including
PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes providing an alternate water
supply by constructing and extending water
niains, and installing connections and service to
the city distribution system for affected residents;
reactivating Municipal Well #35 after
constructing a granular activated carbon water
treatment facility at the well; and abandoning
contaminated private wells. The estimated
present worth cost for this remedial action is
$5,820,000, which includes an annual O&M cost
of $436,800 for years 1-5 and $58,800 for years
6-30.

SOUTH MACOMB DISPOSAL #9, 9A, Ml
August 13,1991
SITE HISTORY/DESCRIPTION:
The 159-acre South Macomb Disposal #9,9A site
contains two inactive municipal landfills in
Macomb Township, Macomb County, Michigan,
Land use in the area is predominantly
agricultural and rural, with several adjacent
residences. A small stream, the McBride Drain,
runs along the western and southern boundaries
of the site, and there is a possible wetlands area
located at the site. Until 1989, the estimated 34
residents in the immediate vicinity of the site
used shallow and intermediate aquifers
associated with contamination from landfills as
their drinking water supply. From 1968 to 1975,
South Macomb Disposal Authority (SMDA), a
municipal corporation, used the site to facilitate
the management and disposal of municipal
refuse for five towns in Macomb County. SMDA
acquired the 75-acre area #9 in 1968, accepted
680,000 cubic yards of municipal waste, and
capped the area with soil in 1971. Subsequently,
SMDA acquired the adjacent 84-acre area 9A in
1970, filled it with 1,200,000 cubic yards of
municipal waste, and capped the area with a
mixture of sand, clay and silt in 1975. As a
result of reported fish kills and continued reports
of leachate seepage into McBride Drain, a
number of State investigations between 1976 and
1982 verified that the site was the source of the
leachate problem and prompted SMDA to
upgrade and expand leachate collection systems
along various porh'ons of area 9A. From 1983 to
1984, the State investigations detected
VOC-contaminated ground water in several
residential wells near the site. Consequently,
from 1985 to 1988, SMDA constructed an
additional leachate collection system on area #9,
and a slurry wall across the northern portion of
area #9. In 1989, Macomb Township connected
residences near the site to the municipal water
supply. This ROD addresses onsite
contaminated ground water as operable unit 1
(OUl). A future ROD will address the landfill
contents as OU2. The primary contaminants of
concern affecting the ground water are VOCs
including benzene and toluene; other organics
including phenols; and metals including arsenic
and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing extraction wells in the intermediate
aquifer, both within and outside the site
boundary and subsurface drains in the shallow
aquifer along the periphery of the waste deposits
in both sites #9 and 9A; collecting ground water
and leachate in a series of collection sumps,
followed by pumping to the onsite ground water
treatment system; treating the contaminated
ground water onsite using air stripping, followed
by granular activated carbon, oxidation/
precipitation, and granular media filtration, with
onsite discharge of the treated water to McBride
Drain; disposing of any treatment residuals
offsite; extending the existing slurry wall along
the east side of area #9; providing a municipal
water supply to any residences within a one-half
mile radius of the site that are not currently
attached; conducting long-term monitoring of
ground water, surface water, sediment of
McBride Drain, leachate, air, and residential
wells; and implementing institutional controls
including deed and ground water restrictions,
and site access restrictions including fencing.
The estimated present worth cost for this
remedial action is $9,264,000, which includes an
annual O&M cost of $224,000.
PERFORMANCE STANDARDS OR GOALS;
Chemical-specific ground water clean-up goals
are based on the more stringent of State
standards or SDWA MCLs, and include benzene
2 ug/1 (State), toluene 100 ug/1 (State), phenols
1,100 ug/1 (State), arsenic 1 ug/1 (State), and

STOUGHTON CITY LANDFILL, Wl
September 30,1991
SITE HISTORY/DESCRIPTION:
The 27-acre Stoughton City Landfill site is a
former waste disposal facility in Stoughton, Dane
County, Wisconsin. The site was an
uncontrolled dump site from 1952 to 1969, and
later from 1969 to 1977 operated as a
State-licensed landfill covering approximately
15 acres. Land use in the area is predominantly
agricultural and residential, with several
wetlands areas located adjacent to the site. In
addition, part of the site lies within the 100-year
floodplain of the Yahara River, located west of
the site. From 1954 until 1962, liquid wastes
Were routinely poured over garbage and burned.
In addition, some liquid wastes were poured
down holes drilled to test auger drilling
equipment. From 1969 to 1977, both solid and
liquid municipal wastes were disposed of at the
Stoughton Landfill. In 1977, the State required
that the site be closed and initiated closure
activities that included constructing a trash
transfer station, placing cover materials, applying
topsoil, and seeding. As a result of improper
disposal activities, a number of investigations
were conducted by the State and EPA that
revealed ground water contamination resulting
from leachate discharge and surface water run-
off from the landfill. This ROD addresses soil
and ground water contaminated by leaching
tandfilled waste. The primary contaminants of
concern affecting the soil, debris, and ground
water are VOCs including benzene,
tetrahydrofurans (THF), toluene, and xylenes;
pther organics including PAHs; and metals
Deluding arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
placing a solid waste disposal facility cap over
the site; excavating wastes in contact with
ground water along the southeastern and
northeastern sections of the site and
consolidating these wastes under the cap;
pumping and treatment of contaminated ground
water unless additional monitoring indicates that
ground water extraction is not required to
achieve compliance with State quality standards,
and subsequent onsite discharge of the treated
ground water to the Yahara River in compliance
with NPDES effluent limitations; long-term
monitoring of ground water; and implementing
institutional controls and site security measures
including fencing the entire site perimeter. The
estimated present worth cost for this remedial
action is $7,546,000, which includes an annual
O&M cost of $329,600 for years 0-5 and $146,600
for years 6-30.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on State Preventive Action Limits
(PALs), and include THF 10 ug/1.
INSTITUTIONAL CONTROLS:
Land use restrictions will be implemented to
prevent the installation of a well within 1,200
feet of the property boundary and residential
development of the site.

STURGIS MUNICIPAL WELLS, Ml
September 30,1991
SITE HISTORY/DESCRIPTION:
The 5-square-mile Sturgis Municipal Wells site is
an active municipal well field in Sturgis, St.
Joseph County, Michigan. Land use in the area
is predominantly mixed industrial and
residential, with several wetlands areas located
near the site. The estimated 10,000 residents of
Sturgis use the intermediate and deep aquifers as
their drinking water supply. The site includes
the former Wade Electric facility, which closed in
1966 and burned down in 1974, and the Kirsch
Company, which operated as a manufacturing
facility until 1980. These two properties have
been identified as two source areas responsible
for the ground water contamination in the
aquifer used for the municipal water supply.
State investigations starting in 1982 identified
contaminated soil and VOC-contaminated
ground water onsite and extensive ground water
contamination in various wells throughout the
city. This ROD addresses final remediation of
soil and ground water. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
and TCE; and other organics including PAHs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating VOC-contaminated soil using vapor
extraction, followed by activated carbon
adsorption to capture off-gases; regenerating
carbon offsite; excavating and disposing of of fsite
10,890 cubic yards of low level PAH-
contaminated soil (10,000 cubic yards from the
Kirsch property and 890 cubic yards from the
Wade property); onsite pumping and treatment
of ground water using air stripping, followed by
vapor phase granular activated carbon to treat
off-gases; discharging the treated water onsite
either to surface water via a storm sewer or
making the water available for use by the
municipal water system; ground water
monitoring; and implementing institutional
controls, and site access restrictions including
fencing. A contingency plan would be
developed to allow for the rapid installation of a
mobile water supply treatment system, should it
be required at any of the existing municipal
supply wells. The estimated present worth cost
for this remedial action is $13,810,000 for
discharge of treated ground water to a storm
sewer, which includes an annual O&M cost of
$644,600 for years 0-3 and $598,000 for years
4-30.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals for VOCs
are based on State standards, and include PCE
14 ug/kg and TCE 60 ug/kg. Soil containing
PAHs will be excavated to 330 mg/kg, based on
State standards. Chemical-specific ground water
clean-up goals are based on State standards, and
include benzene 1 ug/1, PCE 1 ug/1, and TCE
3 ug/1.
INSTITUTIONAL CONTROLS;
Ground water use restrictions will be
implemented to prevent further installation of
wells in the City of Sturgis pending restoration
of the well field and associated aquifers.

SUMMIT NATIONAL LIQUID DISPOSAL SERVICE (AMENDMENT), OH
November 2,1990
SITE HISTORY/DESCRIPTION:
The 11.5-acre Summit National Liquid Disposal
Service site is a former liquid waste disposal
facility in rural Deerfield Township, Ohio. The
site contains two ponds, an inactive incinerator,
and several vacant buildings. Surrounding the
site are several residences, two landfills, light
industries, and farmland. Fifteen to twenty
residential wells are located within 1,000 feet of
the site. From 1973 to 1978, Summit National
operated a solvent recycling and waste disposal
facility onsite. Oil, resins, sludge, pesticide and
plating wastes, and other liquid wastes were
stored, incinerated, and buried or dumped onsite
during facility operations. In 1978, the State
ordered Summit National to stop accepting
waste material and to remove all liquid waste
from the site. In 1980, EPA removed three bulk
tanks, which contained approximately 7,500
gallons of hexachlorocyclopentadiene along with
contaminated soil, and treated some
contaminated water. In 1981, the State and eight
of the potentially responsible parties removed
additional drums, tanks, surface debris, and a
small amount of contaminated soil from the site.
Subsequently, EPA took interim measures to
control the migration of contaminants offsite and
excavated an underground storage tank. During
the RI/FS, conducted from 1984 to 1987, EPA
documented onsite contamination of soil,
sediment, ground water, and surface water by a
variety of organic and inorganic compounds.
Contaminated property outside the site
perimeters also was found. This ROD amends a
1988 ROD that provided for remediation of
contaminated soil, sediment, debris, ground
water, and surface water. Based on further site
investigations, EPA modified their original goal
of containing contaminated media to one of
long-term cleanup at the site. In both the 1990
proposed remedy for this ROD amendment and
the 1988 ROD, the remedy for the most highly
contaminated soil and sediment is excavation
and treatment; however, the ground water
extraction method in the 1990 proposed remedy
was significantly different from the 1988 ROD
and employed a different technology that will
result in long-term soil cleaning, thus eliminating
the need for the containment of contaminants
with a slurry wall and multi-layer cap as
provided in the 1988 ROD. The primary
contaminants of concern affecting the soil,
sediment, debris, ground water, and surface
water are VOCs including benzene, TCE,
toluene, and xylenes; other organics including
PAHs, PCBs, and phenols; and metals including
arsenic and chromium.
SELECTED REMEDIAL ACTION:
The selected amended remedial action for this
site includes expanding site boundaries to
include contaminated areas along the site
perimeters; excavating and incinerating onsite
24,000 cubic yards of soil excavated to a depth of
2 feet, 4,000 cubic yards of sediment from the
site perimeter, drainage ditches and offsite
ponds, and 900 to 1,600 buried drums, followed
by backfilling the residual ash onsite, or
disposing of the ash offsite in a RCRA facility if
the waste does not meet EPA performance
standards; regrading the site; installing a
permeable soil cover over 10.6 acres of the site
with gas vents for treating and monitoring
potential air emissions; dismantling and/or
demolishing all onsite structures, and disposing
of debris onsite; collecting ground water from
the upper aquifer via pipes and drains, and
constructing additional extraction wells in the
lower aquifer to augment the pipe and drain
system, followed by treating ground water
onsite; collecting and treating onsite surface
water from the two onsite ponds and drainage
ditches using precipitation, flocculation,
coagulation, oil and water separation, filtration,
and carbon adsorption using a pipe and drain
collection system; excavating sediment after

Site features include a warehouse, an incinerator,
above-ground storage tanks, a laboratory, and
process buildings and associated lagoons. A
trout stream, Black Creek, is located
approximately 1,500 feet south of the site and
forms a broad and flat wetland. From 1969 to
1980, Thermo Chem received, distilled, and
regenerated solvents, paint wastes, and
antifreeze into usable solvents. Unrecoverable
materials and by-products including sludge and
residues were incinerated onsite. The Thomas
Solvent Company, which lies adjacent to, and is
owned by Thermo Chem, has been included as
part of the site because it is suspected to be a
source of ground water contamination. The
Thomas Solvent Company was operated as a
hazardous waste hauling facility for Thermo
Chem and collected waste for recycling and
returned the material to customers. Wastewater
generated from the distillation and
equipment-cleaning process at Thermo-Chem
was discharged onsite into a series of three
interconnected lagoons. In addition,
approximately 3,500 drums containing raw and
recycled materials were stored in an onsite
underground storage tank farm area during the
years of operation. Former onsite personnel
indicated that sludge was occasionally buried
onsite, and that onsite chemical spills frequently
occurred. In response to investigation activities
during 1988 and 1991, EPA conducted an
emergency removal of drums and materials
containing hazardous waste. Federal
investigations in 1990 indicated that contaminant
releases were one source of ground water
contamination. This ROD addresses the source
of contamination by remediation of soil, sludge,
debris, and ground water up to the point where
ground water discharges into Black Creek as
operable unit 1 (OU1). A future ROD will
address OU2, the contamination problems within
Black Creek and ground water contamination
south of Black Creek. The primary contaminants
of concern affecting the soil, sludge, debris, and
ground water are VOCs including benzene,
toluene, and xylenes; other organics including
PAHs, PCBs, and pesticides; metals including
arsenic, chromium, and lead; and other
inorganics.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, removing, and incinerating offsite
approximately 2,000 cubic yards of soil and
sludge; treating and disposing offsite any ash or
residuals produced from offsite incineration;
installing an in-situ vapor extraction (ISVE)
system and treating onsite approximately 9.5
acres of remaining contaminated soil; conducting
a treatability study to determine the feasibility of
enhancing the natural biodegradation of organic
compounds in the soil undergoing ISVE
treatment; treating gases emitted from the
extraction wells using a fume-rich incinerator;
treating liquid from the vapor extraction process
onsite; covering the site with clean soil and
vegetation, if necessary; decontaminating,
demolishing, and disposing of offsite all onsite
buildings and structures; onsite pumping and

VERONA WELL FIELD, Ml
June 28,1991
SITE HISTORY/DESCRIPTION:
The Verona Well Field site consists of a well
field, three contaminant sources, and the ground
water between the source areas and the well
field in Battle Creek, Calhoun County, Michigan.
Surrounding land use is mixed residential and
industrial. Part of the site lies within the
100-year floodplain of the Battle Creek River,
which runs southwesterly through the site. The
site overlies a surficial glacial aquifer and a
deeper bedrock aquifer, both of which are local
sources of drinking water. The estimated 53,000
people who reside within the City of Battle
Creek and several surrounding communities and
industries use the Verona Well Field, screened
within the bedrock aquifer, as their primary
drinking water source. From 1964 until 1984, the
Thomas Solvent Company stored, blended,
repackaged, distributed, and disposed of
industrial solvents at both their Thomas Solvent
Raymond Road (TSRR) facility and their Thomas
Solvent Annex facility. Three source areas of
contamination have been identified onsite,
including the TSRR and Annex facilities, and a
paint shop in the Grand Trunk Western Railroad
(GTWRR) marshalling switching yard.
Contamination of the onsite soil has resulted
from surface spills, leaking drums, and leaking
underground storage tanks. During the 1960's
and 1970's, the paint shop in a car department at
the GTWRR used solvents for degreasing and
cleaning purposes. Spent solvents were either
disposed of directly on the ground or in a drum
pit outside the car department building. In 1981,
ground water contamination was discovered at
the site, which resulted in a number of
investigations conducted by the State and EPA.
In 1984, an Initial Remedial Measure (IRM)
provided for the conversion of 12 production
wells into purge wells, and the installation of
3 new production wells and an air stripper. A
1985 ROD addressed remediation of soil and
ground water at the TSRR facility, and provided
for treatment of contaminated soil using vapor
extraction with off-gas treatment, and pumping
and treatment of contaminated ground water.
This ROD addresses the second and final
operable unit for soil and ground water
contamination at the site. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
TCE, toluene, and xylenes; other organics
including phenols; and metals including arsenic
and chromium.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
treating soil at the Thomas Solvent Annex and
the GTWRR paint shop area using in-situ soil
vapor extraction; continuing the operation of the
existing purge wells and air stripper; installing
additional purge wells, and treating extracted
ground water from the well field and source
areas onsite using air stripping and vapor phase
carbon adsorption, with onsite discharge to
surface water; and monitoring ground water,
soil, surface water discharge, and air. The
estimated present worth cost for this remedial
action is $15,300,000, which includes an annual
O&M cost of $840,000 for a maximum of 30
years.
PERFORMANCE STANDARDS OR GOALS:
Clean-up goals for soil and ground water are
based on State standards. Chemical-specific
goals for soil include benzene 20 ug/kg,
PCE 10 ug/kg, TCE 60 ug/kg, toluene

WASHINGTON COUNTY LANDFILL, MN
November 15,1990
SITE HISTORY/DESCRIPTION:
The 40-acre Washington County Landfill site is
an inactive sanitary landfill in Lake Elmo,
Washington County, Minnesota. Land use in the
area is predominantly residential and
agricultural. Lake Jane is located 250 feet north
of the landfill. The site overlies the St. Peter
Sandstone and Prairie du Chien Dolomite
aquifers, both of which are sources of drinking
water for an estimated 3,000 residents living
within 3 miles of the site. From 1969 to 1975,
Washington and Ramsey counties used the site
as a sanitary landfill. The landfill is located in
an old gravel pit, and was constructed without
a liner. An area of approximately 35 acres was
filled with solid waste to an average depth of
approximately 30 feet. About 2.57 million cubic
yards of solid waste, excluding cover material,
were disposed of in the landfill. The waste was
primarily composed of residential waste with
smaller amounts of demolition and commercial
waste. Monitoring by Washington County in
1981 revealed low-level VOC contamination,
which poses a health risk based on long-term
ingestion of ground water. In 1983, four nearby
private wells also were found to contain low
levels of VOCs, and drinking water well
advisories were issued. A 1984 ROD provided
for the installation and operation of a ground
water gradient control and spray-irrigation
treatment system at the landfill. It also provided
a safe drinking water supply to residents with
drinking water well advisories and initiated
monitoring of the ground water gradient control
system. This ROD addresses a final remedy for
drinking water supply as part of a second
operable unit. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, PCE, TCE, and xylenes.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
providing a municipal drinking water supply
system to supply drinking water to 10 homes
with private wells that have been affected by the
contaminant plume; and continued operation of
the gradient control well and spray-irrigation
treatment system for the first operable unit,
which consists of four gradient control wells,
two onsite spray-irrigation treatment areas, and
onsite discharge to surface water. The estimated
present worth cost of this remedial action is
$400,000, which includes an annual O&M cost of
$2,469.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on Recommended Allowable Limits

ZANESVILLE WELL FIELD, OH
September 30,1991
SITE HISTORY/DESCRIPTION:
The 100-acre Zanesville Well Field site is an
active manufacturing and municipal well site in
Zanesville, Ohio. The site is composed of the
28-acre United Technologies Automotive (UTA)
facility and the 72-acre City of Zanesville Well
Field. Land use in the area is predominantly
residential and industrial. The Muskingum
River borders the manufacturing area on the
west and the well field on the east From 1929
to the present the UTA property was used for
various types of manufacturing activities.
During the early 1970's, a 10-foot wide, 75-foot
deep onsite well was filled in by using
demolition material and approximately 121 steel
drums, some of which contained TCE.
Additionally, TCE-based solvents were stored in
a bulk storage tank adjacent to the well, and
other waste solvents were stored in drums
located near storm sewer basins. After EPA
investigations in 1981 revealed VOC
contamination in onsite ground water, the use of
three wells at the Zanesville Municipal Well
Field was discontinued. In 1983, approximately
145 tons of waste were removed from the filled
in well by UTA when the well was properly
abandoned and sealed. Two of the three onsite
wells are currently part of a ground water
interceptor system, in which extracted
contaminated water is discharged directly to the
Muskingum River. This ROD addresses
contaminated soil on and around the UTA
facility, contaminated ground water under and
around the Zanesville Well Field and the UTA
facility, and the sources of the ground water
contamination. The primary contaminants of
concern affecting the soil and ground water are
VOCs including TCE and dichloroethylene;
metals including arsenic, chromium, and lead;
and other inorganics.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating approximately 36,000 cubic yards of soil
and source areas contaminated by VOCs using
in-situ vapor extraction, followed by activated
carbon to control off-gases; regenerating the
spent carbon from the air stripping process;
treating onsite 1,800 cubic yards of
inorganic-contaminated soil using soil washing;
replacing the treated soil onsite; disposing of the
concentrated waste and treatment residuals
offsite, with further treatment, if needed;
pumping and onsite treatment of contaminated
ground water using air stripping; and
implementing site access restrictions to the UTA
property, and to the interceptor wells, discharge
pipes, and treatment facilities located in the
Zanesville City Well Field. The estimated
present worth cost for this remedial action is
$2,972,450, which includes a present worth O&M
cost of $1,952,300.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based
on risk-based levels for a cumulative excess
lifetime cancer risk less than 10"6 and an HI<1,
and include TCE 6.3 ug/kg and lead 12 mg/kg.
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include TCE
5 ug/1.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to control
future use of the UTA facility until soil clean-up
levels have been met and to control the use and
placement of wells in the affected area until
ground water clean-up levels have been met.

CIMARRON MINING, NM
September 6,1991
SITE HISTORY/DESCRIPTION;
The Cimarron Mining site consists of two
inactive ore-processing mills in Carrizozo,
Lincoln County, New Mexico. Operable Unit 2
(OU2), which is the focus of this ROD, addresses
contamination at the 7.5-acre Sierra Blanca mill
location. Land use in the area is predominantly
residential, with an estimated 900 people
residing within 1/2 mile north/northwest of the
site. Onsite features at the Sierra Blanca location
include two buildings, four discharge pits, one
cinder block trench, a septic tank system, and
numerous process tanks and material piles.
Prior to 1970, Scott-Tex, Inc., used the site to
recover a variety of metals from ores transported
to the site. In the early 1970's, the mill was
temporarily shut down, and ownership was
transferred to the town of Carrizozo. The site
was then leased and used to recover platinum
and silver from ore material. In 1982, after a
possible spill occurred at the Cimarron mill,
milling operations were relocated to the Sierra
Blanca mill. During operations, the facility
discharged contaminated liquids onsite and
produced approximately 570 cubic yards of
contaminated material piles and other waste
sludge. In 1990, EPA investigations revealed
43 cubic yards of tank sediment, 182 cubic yards
of material pile soil and rock, and 345 cubic
yards of discharge pit sediment and soil
contaminated with high concentrations of metals,
particularly lead at the Sierra Blanca location. A
1990 ROD addressed contamination of the
original Cimarron mill, as OU1. This ROD
addresses the final remedial action of the soil
and waste piles at the Sierra Blanca mill location,
as OU2. The primary contaminants of concern
affecting the soil, sediment, debris, and sludge
are metals including arsenic and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for the site includes
excavating and treating onsite 225 cubic yards of
contaminated material piles and tank sediment,
including cinder block trench sediment which
failed the TCLP test, using cement solidification
and stabilization; excavating and disposing of
345 cubic yards of contaminated surficial soil
and sludge that did not fail the TCLP test in an
onsite discharge pit along with the solidified/
stabilized waste; capping the discharge pit with
an impermeable cover; removing all process
drums, and decontaminating tanks and
associated piping onsite; filling in the discharge
pits and the cinder block trench with onsite soil
and covering with clean fill; installing additional
ground water monitoring wells; monitoring
ground water; and implementing institutional
controls including deed restrictions, and site
access restrictions including fencing and zoning
ordinances. The estimated present worth cost
for this remedial action is $79,000, which
includes a total present worth O&M cost of
$10,000.
PERFORMANCE STANDARDS OR GOALS:
Chemical- and action-specific soil clean-up goals
for lead are based on the "Interim Guidance on
Establishing Soil Lead Clean-up Levels at
Superfund Sites," and remediation levels will not
exceed lead 500 mg/kg.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to
regulate use of property, to notify potential
buyers of past activities, and to restrict
permissible uses.

RETRO-CHEMICAL (TURTLE BAYOU), TX
September 6,1991
SITE HISTORY/DESCRIPTION:
The 500-acre Petro-Chemical (Turtle Bayou) site
is in Liberty County, Texas. Current land use in
the area is divided among cropland, pasture,
range, forest, and small rural communities. The
site overlies two aquifers and is located partially
within the Turtle Bayou floodplain. Since 1929,
the site has been used for cattle grazing, timber
collection, and rice farming. Since 1971,
numerous undocumented disposal activities
occurred onsite involving primarily
petrochemical wastes. Waste oils were dumped
in unlined pits and also spread onto Frontier
Park Road, an access road through the site.
These disposal activities have resulted in
contamination of onsite soil and ground water.
Waste samples collected during State and EPA
investigations indicated elevated concentrations
of metals, VOCs, and organics. A 1987 ROD
addressed operable unit 1 (OU1), and provided
for excavation of highly contaminated soil from
Frontier Park Road; placement of the highly
contaminated soil in a temporary RCRA vault;
filling excavated areas with clean soil; and
resurfacing the entire length of the road. This
ROD for OU2 focuses on three areas of
contamination at the site affecting soil and
ground water contamination, known as the main
waste area, the east disposal area, and the Bayou
disposal area. The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene and xylenes; other
organics including PAHs; and metals including
lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating 302,800 cubic yards of contaminated soil
onsite using in-situ vapor extraction to remove
VOCs, including injecting air below affected soil
to enhance removal of VOCs below the shallow
water bearing zone; controlling vertical air
infiltration using an engineered soil and
synthetic liner cap; consolidating
lead-contaminated soil in the Main Waste Area,
followed by capping; using a slurry wall to
control horizontal migration of ground water;
treating extracted vapors from soil and ground
water using catalytic thermal destruction;
treating ground water using in-situ vapor
extraction/air stripping, including injecting air at
the base of the shallow water-bearing zone to
remove VOCs from ground water; monitoring
ground water; and installing structures to control
surface water run-on and run-off. The estimated
present worth cost for this remedial action is
$26,430,000, which includes a total present worth
O&M cost of $11,466,000.
PERFORMANCE STANDARDS OR GOALS:
Clean-up goals for soil are based on a leaching
model used to determine the remedial levels in
soil required to protect the ground water.
Chemical-specific soil clean-up goals include
benzene 0.35 mg/kg and 10 mg/kg for soil at
depths of greater than 10 feet and less than
10 feet, respectively (leachate model), and lead
500 mg/kg (interim guidance). Chemical-specific
ground water clean-up goals include benzene
5 ug/1 (MCL), lead 15 ug/1 (EPA policy action
level), and xylenes 10,000 ug/1 (health-based).

E.I. DUPONT De NEMOURS (COUNTY RD X23), IA
May 28,1991
SITE HISTORY/DESCRIPTION:
The E.I. DuPont De Nemours (County RD X23)
site is a paint waste disposal site 3.5 miles south
of West Point in Lee County, Iowa. The site is
divided into two subsites, McCarl and Baier,
which are three-fourths of a mile apart. Land in
the area is agricultural, residential, and
woodlands, and the nearest residence is located
500 feet from the McCarl subsite. The site
overlies two water-bearing units, separated by 75
feet of very low permeable clay. The Baier
subsite was used as the primary disposal site,
and the McCarl subsite, purchased in 1986, was
used when weather did not allow access to the
Baier site. From 1949 to 1953, an estimated
48,000 to 72,000 55-gallon waste drums were
disposed of at the two sites. Paint waste was
generally placed in trenches and burned,
resulting in an estimated 4,500 to 7,000 tons of
ash remaining onsite. Paint cans, ash-like
material, and sludge casting were also visible on
the surface of the site. In 1983, an EPA
investigation of the Baier Farm detected levels of
metals and organics in excess of soil background
levels. In addition, ground water monitoring
wells, installed during 1985 and 1986, detected
metal concentrations above MCLs. A 1989
investigation identified the source of
contamination as paint disposed of onsite.
Removal from the Baier site was scheduled for
July 1989 by a Unilateral Administrative Order
from EPA to DuPont, but deferred by a February
1990 amendment. This ROD addresses the soil,
debris, and ground water, as a final remedy.
The ground water was determined to be of little
threat and is not further addressed by this ROD.
The primary contaminants of concern affecting
the soil and debris at both subsites are VOCs
including TCE, toluene, and xylenes; and metals
including arsenic, chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for the site includes
stabilizing/solidifying the contaminated soil at
both subsites, and covering the stabilized mass
with clean soil and vegetation; removing and
disposing offsite all surface debris not amenable
to solidification at an authorized RCRA landfill;
monitoring ground water; and implementing
institutional controls including deed restrictions.
The estimated present worth cost for this
remedial action is $1,400,000. There are no O&M
costs associated with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based
on health-based criteria, and include lead
350 ug/kg, selenium 10 ug/kg, and cadmium
20 ug/kg.
INSTITUTIONAL CONTROLS:
Institutional controls including deed restrictions
will be implemented onsite.

floodplain, but flooding of Caulks Creek occurs
during periods of heavy rain. During the 1960's
and 1970's, Bliss Waste Oil Company used the
site to transport and dispose of waste oil
products (some of which were contaminated
with dioxin), industrial wastes, and chemical
wastes. Liquid wastes were poured into pits,
applied to the ground surface, and stored in
drums and buried. Dioxin-contaminated waste
oil was applied directly to surface soil for dust
control, and spillage from trucks also occurred.
Investigations conducted from 1982 through 1983
concluded that site contamination was not
affecting the ground water; however, some
onsite surface migration of contaminated soil and
sediment had occurred. In 1985, the State
constructed a diversion dike to redirect
stormwater run-off, which flowed through a fill
area containing buried drums; and fenced the
site. A 1986 ROD selected a final remedy for
non-dioxin wastes at the site and an interim
remedy for dioxin waste at the site including
excavation and interim onsite storage of
dioxin-contaminated materials. The interim
remedy has not been implemented. A1988 ROD
for the Times Beach site established the
availability of a thermal treatment unit at the
Times Beach site to treat dioxin-contaminated
sites in eastern Missouri including the Ellisville
Area. This ROD provides a final remedy for
dioxin-contaminated soil, which involves
excavation and direct transport of dioxin wastes
offsite for treatment. The 1986 remedy for
non-dioxin wastes is not affected. The primary
contaminant of concern affecting the soil is
dioxin, an organic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and direct transportation of
approximately 7,000 cubic yards of
dioxin-contaminated soil for treatment at an
offsite temporary thermal treatment unit
constructed at the Times Beach site; disposing of
treatment residuals at the Times Beach site as
nonhazardous solid waste if delisting criteria are
met, or retreating at Times Beach or managing
residuals offsite as a hazardous waste if delisting
criteria are not met. The estimated present
worth cost for this remedial action is $17,530,000.
There are no O&M costs associated with this
remedial action.
PERFORMANCE STANDARDS OR GOALS:
Performance standards for the thermal treatment
of soil include six-nines (99.9999 percent)
destruction and removal efficiency and delisting
of the thermal treatment residue.

SITE HISTORY/DESCRIPTION:
The Ellisville Area site is a former waste oil
disposal site in Ellisville, St. Louis County,
Missouri. The site consists of the 11.6-acre Bliss
property and four contiguous properties where
hazardous substances have been identified.
Land use in the area is mixed residential, rural,
and recreational. Surface run-off at the site
drains to Caulks Creek, a tributary of Bonhomme
Creek, which enters the Missouri River about
1 mile upstream of a city of St. Louis
waterworks intake. The site does not lie in a
floodplain, but flooding of Caulks Creek occurs
during periods of heavy rain. During the 1960's
and 1970's, Bliss Waste Oil Company used the
site to transport and dispose of waste oil
products (some of which were contaminated
with dioxin), industrial wastes, and chemical
wastes. Liquid wastes were poured into pits,

onsite surface migration of contaminated soil and
sediment had occurred. In 1985, the State
constructed a diversion dike to redirect

excavation and interim onsite storage of
dioxin-contaminated materials. The interim
remedy has not been implemented. A 1988 ROD
For the Times Beach site established the
availability of a thermal treatment unit at the
Times Beach site to treat dioxin-contaminated
sites in eastern Missouri including the Ellisville
area. This ROD amends the 1986 ROD because
the pending availability of a thermal treatment
unit at Times Beach has prompted EPA to
reconsider the need for excavation and interim
onsite storage. This ROD also provides a final
remedy for dioxin-contaminated soil, which
involves excavation and direct transport of
dioxin wastes offsite for treatment. The 1986
remedy for non-dioxin wastes is not affected.
The primary contaminant of concern affecting
the soil is dioxin, an organic.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes excavating, and direct transportation of
approximately 7,000 cubic yards of
dioxin-contaminated soil for treatment at an
offsite temporary thermal treatment unit
constructed at the Times Beach site; disposing of
treatment residuals at the Times Beach site as
nonhazardous solid waste, if delisting criteria are

HASTINGS GROUNDWATER CONTAMINATION
(OPERABLE UNIT 1), NE
September 30,1991
SITE HISTORY/DESCRIPTION:
The Hastings Groundwater Contamination site
consists of localized areas where the aquifer is
contaminated with industrial chemicals,
primarily VOCs, in the City of Hastings, Adams
County, Nebraska. This ROD addresses part of
the Colorado Avenue subsite, which is one of
several Hasting Groundwater Contamination
subsites. This subsite consists of contaminated
soil at three industrial properties, which was
addressed in a 1988 ROD as OU9, and a ground
water contaminant plume approximately 1 mile
long, which is the subject of this ROD and
referred to as OU1. Land use in the area is
residential and industrial. The West Fork Big
River lies to the north of the site, and the site is
characterized by a nearly flat ground surface
with a gentle slope to the southeast. The
estimated 23,000 residents of Hastings obtain
their drinking water from a municipal system
that taps into the underlying sole-source aquifer.
From 1967 to 1982, Dravo Corporation, the
former owner of one of the industrial properties,
manufactured heating and air conditioning
equipment onsite and discharged chlorinated
solvents from its vapor degreasing process into
sanitary and storm sewers. Leaky sewer joints
and discharge of storm drains to open ditches
have resulted in seepage of chlorinated
compounds into the soil, and eventually into the
aquifer. In 1983, after 30 years of nonuse,
Hastings municipal well #18 was put back online
to pump ground water, but complaints from
citizens about the odor and taste of the water
prompted the city to remove the well from
service. In 1985, EPA investigated onsite ground
water contamination, including well #18, and
identified onsite TCA, TCE, and PCE
contamination. Monitoring wells showed that
the contaminant plume extended about 1 mile
eastward in the direction of ground water flow.
The source of this contamination was traced to
Dravo's industrial facility. All affected wells
were subsequently shut down. A 1988 ROD
addressed the soil component of the Colorado
Avenue subsite as OU9 and identified treatment
using soil vapor and vacuum extraction
technologies, followed by treatment of extracted
vapor using an activated carbon system, and
monitoring soil, ground water, and air. This
ROD addresses the ground water contamination
component as OU1. Future RODs may address
additional source control measures, subsurface
monitoring, ground water extraction and
treatment, wellhead protection and treatment,
and provide institutional controls. The primary
contaminants of concern affecting the ground
water are VOCs including DCE, PCE, and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes managing the contaminant
plume by pumping a number of pore volumes
(5,550,000 gallons) of VOC-contaminated ground
water, treating the extracted ground water onsite
using granular activated carbon (with a
contingency to use air stripping and emissions
treatment, or UV oxidation), and reusing or
reinjecting the treated ground water;
regenerating spent carbon offsite; and monitoring
ground water quality to measure effectiveness of
the interim action. The estimated present worth
cost for this remedial action is $6,061,000, which
includes an annual O&M cost ranging from
$269,000 to $767,000 for 10 years. EPA has
increased the estimated remedial action
timeframe for this interim action to 15 years.
The total present worth cost of the remedial
action will increase from the 10-year estimate
primarily due to a longer period of O&M.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on State and Federal MCLs, and
include PCE 0.005 mg/1 and TCE 0.005 mg/1.

HASTINGS GROUNDWATER CONTAMINATION
(OPERABLE UNITS 10, 2), NE
September 30,1991
SITE HISTORY/DESCRIPTION:
The Hastings Groundwater Contamination site
consists of localized areas where an aquifer is
contaminated with industrial chemicals in or
near the City of Hastings, Adams County,
Nebraska. Both the source control operable unit
10 (OU10) and ground water operable unit
(OU2) of the North Landfill, a 13.4-acre former
municipal landfill are addressed by this ROD.
Land use near the landfill is mixed residential
and commercial with an active railroad directly
north of the site. The estimated 23,000 residents
of Hastings obtain their drinking water from the
municipal water system, which taps into the
underlying sole-source aquifer. As early as 1938,
brickmakers obtained clay source materials from
the area of the landfill. From 1961 to 1964, the
City of Hastings operated a municipal landfill
onsite and accepted municipal and industrial
wastes including wastes containing VOCs. The
landfill was initially capped, and later in the
1970's an additional 2 feet of capping materials
were added. In 1983, ground water
contamination was discovered when the Stale
sampled the Hastings public water supply
system in response to citizen complaints about
water quality. EPA investigations have
identified VOCs including benzene, TCE, DCE,
and vinyl chloride in the ground water adjacent
to and downgradient from the site. In 1985,
soil-gas samples indicated that the vadose zone
above the aquifer was contaminated. This ROD
provides an interim remedy for both OUs.
Future RODs may address additional source
control measures, subsurface monitoring, ground
water extraction and treatment, wellhead
protection and treatment, and provision of
institutional controls. The primary contaminants
of concern affecting the soil and ground water
are VOCs including TCE, DCE, and vinyl
chloride.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes geotechnical testing of the
existing landfill cap, improving the present cap
through regrading to promote surface run-off,
and revegetating the landfill surface; pumping
and onsite treatment of contaminated ground
water with a technology to be determined after
further testing, but will be either air stripping or
UV oxidation; monitoring the vadose zone,
saturated zones, and ground water; and
implementing institutional controls including
deed restrictions, and site access restrictions such
as fencing. The estimated present worth cost for
this remedial action will range from $2,300,000 to
$4,000,000, based on ground water treatment and
discharge options.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include
TCE 5 ug/1, cis 2-DCE 70 ug/1, trans 1,2-DCE
100 ug/1, and vinyl chloride 2 ug/1.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented onsite to
prevent construction, and ensure cap integrity.

JOHN DEERE (OTTUMWA WORKS LANDFILL), IA
September 23,1991
SITE HISTORY/DESCRIPTION:
The 105-acre John Deere (Ottumwa Works
Landfill) site is an active agricultural equipment
manufacturing and assembly facility in
Ottumwa, Wapello County, Iowa. Land use in
the area is predominantly residential, with
wetlands located within 1,000 feet of the site
across the Des Moines River. All of the site lies
within the 100-year floodplain of the Des Moines
River, and a drainage ditch borders the site on
the east side. The estimated 27,000 Ottumwa
residents use municipal water obtained from the
Des Moines River as their drinking water
supply. The municipal intake is located
approximately 1,000 feet upgradient from the
site. Black Lake, located 150 feet east of the site,
is used as an additional water source on an
infrequent basis, contributing approximately 1/2
to 1-1/2 percent of the total annual volume of
water distributed by the Ottumwa Water Works.
From 1911 to 1973, Deere & Company buried
plant-generated wastes including solvents, paint
sludge, heat treating cyanide, heat treating
sludge, petroleum distillates, and foundry sand
in the shallow alluvium underlying the site.
After landfilling, some of the wastes were
burned onsite on a regular basis. In 1965, Deere
& Company acquired the southwestern portion
of the site, which had been used previously as a
salvage yard. In the late 1980's, investigations of
the disposal areas identified subsurface soil and
ground water contamination by VOCs, other
organics, and metals. This ROD addresses the
disposal areas, the drainage ditch, and Black
Lake surface water. The primary contaminants
of concern affecting the soil, sediment, debris,
and ground water are organics including PAHs;
and metals including arsenic, chromium, and
lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
implementing institutional controls including
deed restrictions, and site access restrictions
including maintaining the perimeter fence. The
estimated present worth cost for this remedial
action is $4,000. There are no O&M costs
associated with this remedial action since fence
maintenance is covered by the facility's operating
budget.

KEM-PEST LABORATORIES, MO
December 31,1990
SITE HISTORY/DESCRIPTION:
The 6-acre Kem-Pest Laboratories site is a former
pesticide production facility located in Cape
Girardeau County, Missouri. Site features
include a concrete block building that housed the
pesticide formulation operation and currently
holds approximately 11,200 gallons of
contaminated water in its basement; six storage
tanks used for storing solvents and oil; and a
lagoon used for the disposal of sewage and plant
waste. An unconfined aquifer system lies within
the alluvial and colluvial deposits at the site.
From 1965 to 1977, Kem-Pest Laboratories
formulated various pesticide products including
liquid pesticides, granular insecticides and
herbicides, and pesticide dust onsite. Wastes
generated from pesticide production contained
several pesticides including aldrin, dieldrin,
endrin, and heptachlor. Plant wastes were
disposed of in the onsite lagoon. No production
or disposal activities have occurred onsite since
1977, and the lagoon was backfilled with clay by
the owner in 1981. Based on Federal
assessments and investigations conducted in
1981, it was determined that the lagoon and the
formulation building were the most significant
sources of site contamination. Ground water
contamination has occurred from the migration
of contaminants from the soil within the lagoon;
ground water may also act as a flushing
mechanism for contaminants in the subsurface
soil. A 1989 ROD addressed OU1, the
contaminated surface soil in the lagoon; surface
soil in the lagoon area and near the formulation
building; and sediment in drainage channels
onsite and offsite. This ROD addresses pesticide
contamination in the formulation building,
ground water, and surface water, as OU2. The
primary contaminants of concern affecting debris
and surface water are VOCs including benzene;
other organics including pesticides; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
decontaminating the formulation building by
surface layer removal; dismantling
approximately 50 tons of interior structures and
formulation equipment not amenable to
decontamination, followed by offsite incineration
and disposal of decontaminated and dismantled
debris; implementing additional decontamination
measures including scarification and applying a
sealant to the concrete floors, if necessary;
collecting and treating onsite approximately
11,200 gallons of water that has collected in the
basement of the formulation building using
activated carbon adsorption, with onsite
discharge of the water and offsite carbon
regeneration or disposal; long-term ground water
and surface monitoring; and implementing
institutional controls. The estimated present
worth cost for this remedial action is $727,000,
which includes an annual O&M cost of $5,000
for 30 years.
PERFORMANCE STANDARDS OR GOALS:
No Federal or State clean-up standards exist for
remediation of contaminated structures in regard
to risks posed by direct contact. EPA has
determined that a 10"5 individual lifetime excess
cancer risk will be protective of human health
from risks associated with contaminated
structures. Performance standards for inhalation
of pesticides are the worker permissible exposure
limits as defined by OSHA regulations including
aldrin 0.25 mg/m3 and dieldrin 0.25 mg/m3.
INSTITUTIONAL CONTROLS:
Institutional controls will be implemented to
limit future use of the formulation building to
commercial or industrial activities.

LEE CHEMICAL, MO
March 21,1991
SITE HISTORY/DESCRIPTION:
The 2.5-acre Lee Chemical site is a former water
treatment plant and chemical repacking and
distributing facility in Liberty, Clay County,
Missouri. Land use in the area is commercial
and rural. The estimated 17,000 people who
reside in Liberty obtain drinking water from
municipal water wells located approximately
2,000 feet southeast of the site. These wells draw
water from the alluvial aquifer underlying the
site. From 1920 to 1962, the city of Liberty used
the site as the city's water treatment plant. From
1965 until 1975, when the city repossessed the
property, the site was leased to Lee Chemical
Company for packaging and distributing
commercial and industrial cleaning solvents and
other chemicals, some of which were reprocessed
onsite in 55-gallon drums. In 1977, as required
by EPA, the city removed and disposed of
approximately three hundred 55-gallon drums of
waste offsite. In 1979, low levels of TCE were
detected in the public water supply wells.
Subsequent EPA and State investigations
revealed contaminated ground water, soil, and
deteriorated drums and chemical containers; and
in 1982 the city and State identified the site as a
source of TCE contamination in the public water
supply. In 1983, the onsite water plant building
and its contents were demolished and disposed
of offsite. In 1984, in an effort to contain the
contaminated ground water plume and reduce
TCE levels in the water supply, the city
discharged water from the most highly
contaminated of its municipal water wells
through an abandoned sewer line to the
Missouri River and Shoal Creek. Later that year,
an abandoned municipal well onsite was added
to the plume control measure and the discharge
was diverted to an abandoned water main to
nearby Town Branch Creek. Currently, no
detectable levels of TCE are found in wells
connected to the water supply system. This
ROD addresses soil and ground water
contamination, and provides a final remedy for
the site. The primary contaminants of concern
affecting the soil and ground water are VOCs
including TCE.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
installing an in-situ aqueous soil washing system
consisting of infiltration trenches to enhance the
flushing of contaminants from onsite soil to the
underlying aquifer; pumping ground water to
flush contaminants from the underlying aquifer
to the extraction system and to control ground
water movement away from the site, followed by
onsite discharge to surface water; implementing
a contingency phase ground water treatment
project consisting of air stripping or other
treatment methods, if additional treatment of
discharge water becomes necessary to meet
health based risk levels, existing NPDES permit
limits, or other ARARs; and monitoring ground
water and air. The estimated present worth cost
for this remedial action is $550,000, which
includes an annual O&M cost of $52,000 for 5
years. If treatment is deemed necessary, the
revised present worth cost for this remedial
action is $670,000, which includes an annual
O&M cost of $67,000 for 5 years.

LEHIGH PORTLAND CEMENT, IA
June 28, 1991
SITE HISTORY/DESCRIPTION:
The Lehigh Portland Cement site is composed of
two areas: the 150-acre Lehigh Portland Cement
Company (LPCC) cement production facility,
and the 410-acre Lime Creek Nature Center
(LCNC), in Mason, Gordo County, Iowa. Land
use in the area is rural, agricultural, and
industrial. The site overlies an aquifer that
serves as a source of water for 12 nearby wells;
and municipal water is obtained from a deeper
aquifer. Calmus Creek borders the site and
discharges to the Winnebago River, located
within a mile of the site. From 1911 to the
present, the LPCC has manufactured cement
products. As a result of operations, site features
currently include four abandoned quarries at the
LPCC area, which were worked until the 1950's,
and subsequently were filled in with water, and
numerous tailings piles. The water bodies are
known as Blue Waters Pond, Arch Pond, Cooling
Waters Pond, and Area C Pond. During its
history, the LPCC disposed of cement kiln dust
(CKD) in several onsite piles and in Area C
Pond. The LCNC area was used by LPCC to
quarry materials until 1979, and subsequently
was backfilled with CKD from the parent site
and sold. Consequently, the LCNC quarries also
have become ponds, including Quarry Pond. In
1981, hydrochemical tests of Blue Waters Pond
on the LPCC area indicated high alkalinity.
Subsequent investigations indicated that the
ponds on the LCNC area also have high pH
levels, although water quality is better than at
the LPCC area. Testing showed that CKD was
the cause of high alkalinity, and that
contamination of the aquifers has occurred. In
addition, a flow control structure installed on the
southeastern corner of Blue Waters Pond allowed
highly alkaline water to discharge into Calmus
Creek. Subsequently, overflow prevention
measures at Blue Waters Pond were
implemented by LPCC, but seepage to Calmus
Creek continued. This ROD addresses the CKD,
ground water, and surface water as a final
remedy. Elevated pH of ground water and
surface water also is of potential concern.
SELECTED REMEDIAL ACTION:
The selected remedial action for the LPCC area
includes dewatering Blue Waters, Area C, and
Arch Ponds, and treating pond water using acid
neutralization, followed by ion exchange or
reverse osmosis if needed, with onsite discharge;
excavating and consolidating CKD from Blue
Waters and Arch Ponds within Area C Pond,
followed by constructing a clay cap over Area C
Pond; constructing a cap over the existing area
known as the CKD Reclamation Area; collecting
shallow ground water via sumps and a seep
collection system constructed in the base of Blue
Waters and Area C Ponds, and treating the
ground water in the onsite treatment system
before onsite discharge; monitoring ground
water, surface water, and treated discharge; and
implementing institutional controls including
deed restrictions. The selected remedial action
for the LCNC area includes constructing a dam
across Quarry Pond and draining the western
portion of the pond; excavating CKD within the
western portion of Quarry Pond and
consolidating the CKD within an exhausted
quarry east of the pond; constructing a clay cap
over the exhausted quarry; consolidating CKD
from all other LCNC areas in the Badlands area,
and constructing a clay cap over the consolidated
material; allowing Quarry Pond to refill; and
monitoring ground water and surface water.
The estimated present worth cost for remedial

MID-AMERICA TANNING, IA
September 24,1991
SITE HISTORY/DESCRIPTION:
The 98.7-acre Mid-America Tanning site is a
former leather tannery in Sergeant Bluff,
Wood bury County, Iowa. Surrounding land use
is mixed industrial and agricultural. A portion
of the site is bordered by Oxbow Lake and lies
within the 100-year floodplain. The Missouri
River is approximately 1.5 miles to the southwest
of the site and receives discharges from Oxbow
Lake. The facility began onsite processing of
animal hides in 1970. From 1973 to 1989, the site
was used intermittently under various owners as
a chrome tanning operation. Process wastewater
containing debris, chromium, and other
chemicals was discharged to onsite lagoons and
impoundments. Sludge generated from the
process was disposed onsite in the surficial soil
or in disposal trenches. Occasional system
overloads resulted in overflow of chromium
wastewater into Oxbow Lake. In 1980, the State
confirmed the onsite burial of
chromium-containing sludge in trenches, and the
company was cited for permit violations. A1985
EPA investigation identified excessive chromium
contamination in onsite soil, sediment, and
ground water. In 1990, EPA conducted a
removal action that included excavating and
consolidating onsite 1,290 cubic yards of sludge
from the trench disposal area. This ROD
addresses the contaminated soil, impoundment
sediment and water, and the excavated trench
material. A future ROD will address onsite
ground water contamination. The primary
contaminants of concern affecting the soil,
sediment, debris, sludge, and surface water are
metals including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for the site includes
treating 8,300 cubic yards of contaminated soil
and 44,500 cubic yards of impoundment
sediment onsite using in-situ immobilization;
immobilizing 1,293 cubic yards of consolidated
trench sludge onsite, followed by either onsite or
offsite disposal; removing and disposing of
debris offsite and discharging impoundment
water onsite through an NPDES-permitted
outfall or treatment, if needed, with offsite
discharge to a POTW; capping contaminated
areas, and grading and seeding top soil;
conducting ground water monitoring; and
implementing institutional controls including
deed restrictions. A contingent remedy using
ex-situ immobilization will be implemented if
treatability studies determine that the selected
remedy is inadequate. The estimated present
worth cost for this remedial action is $4,857,000,
which includes an annual O&M cost of $21,000.
PERFORMANCE STANDARDS OR GOALS:
Federal and State clean-up standards for
chromium have not been established at this time.
Clean-up objectives are based on a Iff4 cancer
risk to human health and include hexavalent
chromium 2,490 mg/kg.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented at the site
to ensure that it is not used for residential or
agricultural purposes, and that buildings are not
constructed on the capped areas.

PEOPLE'S NATURAL GAS, IA
September 16,1991
SITE HISTORY/DESCRIPTION:
The 5-acre People's Natural Gas site is a former
coal gasification plant in Dubuque County, Iowa.
The City of Dubuque maintains a public works
garage on the eastern portion of the site, and the
Iowa Department of Transportation owns the
western portion. The site is located 300 feet west
of the Mississippi River, and is within the
Mississippi River floodplain. In addition, the
site overlies a silty sand unit and an alluvial
aquifer, which has been determined to be a
potential source of drinking water. Surrounding
land use is primarily industrial and commercial,
with adjacent residential areas. From at least the
1930's to 1954, the site was used to manufacture
gas. By-products produced during this process
included coal tar, which was stored in an
underground tank and an above-ground tank,
and cyanide-bearing woodchips, which were
buried on the eastern portion of the site. From
1954 to 1964, the site was used as a natural gas
distribution, storage, and maintenance facility.
In 1986, EPA investigations identified extensive
contamination of onsite soil and ground water at
the site. In 1989, the PRPs conducted a removal
action that included excavating 5,500 cubic yards
of PAH-contaminated soil from the western
portion of the site, removing tanks used to store
coal tar, installing a leachate collection system to
prevent contamination from leaching into the
alluvial aquifer; and implementing institutional
controls. This ROD addresses both soil and
ground water contamination, as a final remedy.
The primary contaminants of concern affecting
the soil and ground water are VOCs including
benzene, toluene, and xylenes; and other
organics including PAHs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and incinerating an estimated 18,500
cubic yards of contaminated soil offsite; treating
the soil and ground water within the silty sand
unit, which are contaminated with coal tar
wastes using in-situ bioremediation; pumping
and onsite treatment of contaminated ground
water using air stripping, followed by offsite and
storm sewers discharge to a POTW; monitoring
ground water and air; and implementing
institutional controls such as ground water and
land use restrictions, as well as site access
restrictions including fencing. A contingency for
ground water treatment includes engineering
controls and an ARAR waiver if the extraction
system does not achieve clean-up levels. The
estimated present worth cost for this remedial
action is $8,000,000, which includes an estimated
O&M cost of $788,000 for 10 years.
PERFORMANCE STANDARDS OR GOALS:
Federal and State clean-up standards for soil
have not been established at this time.
Therefore, goals for soil cleanup are based on a
carcinogenic risk level of 10 , and include
500 mg/kg for total PAHs and carcinogenic
PAHs 100 mg/kg. Remediation levels for
ground water are based on SDWA MCLs, and
include benzene at 1 ug/1.
INSTITUTIONAL CONTROLS:
Ground water and land use restrictions will be
implemented onsite to prevent direct contact
with contaminants.

SHAW AVENUE DUMP, IA
September 26,1991
SITE HISTORY/DESCRIPTION:
The 26-acre Shaw Avenue Dump site is a
chemical waste site in Charles City, Floyd
County, Iowa. Land use in the area is
predominantly residential. Part of the site lies
within the 100-year floodplain of the Cedar
River, and a wetlands area is located
approximately 600 feet south of the site. From
1899 to 1964, Charles City used the site as a
municipal landfill for waste incineration, and
disposal of liming sludge from the city's POTW.
Asphaltic materials continue to be disposed of in
the onsite landfill. Additionally, from 1949 to
1953, chemical wastes generated by chemical
batch processing of arsenic and compounds used
in the production of animal pharmaceuticals at
Salsbury Laboratories were disposed of onsite.
Between 1977 and 1981, the State issued reports
based on studies of the site and surface water
that documented elevated levels of metals in an
abandoned gravel pit near the site.
Approximately 14,000 to 28,000 cubic feet of
chemical waste and 10,000 tons of solid waste
from the POTW including sludge containing
hazardous waste from Salsbury Laboratories, and
associated contaminated soil are currently
present onsite. Leaching of contaminants,
especially arsenic, from 370 cubic yards of
chemical fill and adjacent soil into ground water
is thought to be the principal threat at the site.
A 200-gallon underground storage tank (UST) is
located within the vicinity of the chemical fill,
and also is considered to be a possible source of
onsite contamination. This ROD addresses the
chemical fill, surrounding contaminated soil, and
the underground gasoline tank as operable unit
1 (OU1). A future ROD will address
contaminated ground water as OU2. The
primary contaminants of concern affecting the
soil and debris are VOCs including benzene,
toluene, and xylenes; other organics including
PAHs; metals including arsenic and lead; and
other inorganics.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating the chemical fill and soil using in-situ
fixation and stabilization, followed by
constructing a low permeability cap over the
fixed and stabilized fill; conducting treatability
studies to determine the effectiveness of the
treatment, and if treatment is not effective,
issuing an ESD and disposing of the waste
offsite; removing and disposing of offsite the
underground gasoline tank; monitoring ground
water quality; and implementing institutional
controls including deed restrictions, and site
access restrictions including fencing. The
estimated present worth cost for this remedial
action is $513,400, which includes an annual
present worth O&M cost of $65,550.
PERFORMANCE STANDARDS OR GOALS:
Action-specific soil clean-up goals are based on
State and Federal standards, RCRA Land
Disposal Restrictions, OSHA, RCRA Toxic
Characteristic Leachate Procedure, and UST
regulations, and include arsenic 50 mg/kg and
cadmium 20 mg/kg.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
construction, installation, and maintenance of
any ground water wells. Access easements also
will be implemented to prevent unauthorized
entry to the site.

ANACONDA SMELTER, MT
September 23,1991
SITE HISTORY/DESCRIPTION:
The 6,000-acre Anaconda Smelter site is a former
copper and ore processing facility in Deer Lodge
County, Montana. Land use in the area is
predominantly residential. The site is bounded
on the north and east, respectively, by the Warm
Springs Creek and Mill Creek, both of which are
potential sources of drinking water. From 1884
until 1980 when activities ceased, the site was
used for ore processing and smelting operations.
Rue dust was generated as a by-product of
copper smelting operations. The majority of flue
dust that was generated was reprocessed, and
the remaining portion was stockpiled at nine
locations on and around the site. In 1988, EPA
conducted an investigation to determine the
nature and extent of the flue dust contamination.
A 1988 ROD addressed the Mill Creek operable
unit (OU15) and documented the relocation of
residents from the community surrounding the
smelter site as the selected remedial action. This
ROD addresses the Flue Dust Operable Unit
(OU11). Subsequent RODs will address further
site contamination in adjacent soil, ground water,
and surface water. The primary contaminants of
concern affecting this site from the flue dust
materials are metals including arsenic, cadmium,
and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating a total of approximately 316,500 cubic
yards of flue dust from the nine flue dust
locations and treating the dust onsite using
cement/silicate based stabilization; disposing of
the treated residuals in an onsite engineered
repository, which will include a soil or clay liner
and a leachate collection system; conducting air
and ground water monitoring; and implementing
institutional controls including land use
restrictions, and site access restrictions. The
estimated capital cost for this remedial action is
$25338,000, with an annual O&M cost of $10,000.
PERFORMANCE STANDARDS OR COALS:
The treatment levels of flue dust cement/silicate
based stabilization will render the material
non-hazardous by meeting RCRA TCLP
regulatory limits, and include levels that will
limit leaching of contaminants to ground water
to arsenic 5 mg/1, cadmium 1 mg/1, and lead
5 mg/1.
INSTITUTIONAL CONTROLS:
Land use restrictions will be implemented.

BRODERICK WOOD PRODUCTS (AMENDMENT), CO
September 24,1991
SITE HISTORY/DESCRIPTION:
The 64-acre Broderick Wood Products (BWP) site
is a former wood treatment facility in Adams
County, Colorado. Land use in the area is
predominantly industrial. The site is one-half
mile south of Clear Creek, a perennial stream.
The nearest residences are less than one-eighth
mile north of the site. From 1947 to 1981, BWP
used the site for treating power poles, fence
posts, railroad ties, and other wood products.
Process wastes from the onsite plant were
disposed onsite in two unlined surface
impoundments in the northwest corner of the
site. Waste seepage occurred just north of the
site and was burned off starting in 1955. Also,
four other ponds were periodically used for this
purpose, and several fires have occurred onsite.
In 1981, BWP submitted a RCRA permitting
application and obtained interim status to
operate its facility, but ceased operations because
of economic conditions. As a result of the waste
disposal practices at BWP, a number of
investigations were conducted by EPA and the
State. In 1981 and 1982, EPA noted several
violations of RCRA requirements; and other site
investigations identified possible contamination
of a trench near the surface impoundments that
had reportedly been used for the disposal of
solid waste, and ground water contamination
downgradient of the surface impoundments.
Additionally, a fire in 1985 damaged the
treatment plant building. Water that was used
to fight the fire has been contaminated with
asbestos and remains in the basement of the
building. A 1988 ROD addressed interim source
control treatment of onsite sludge, as operable
unit 1 (OU1), and provided for excavation and
onsite incineration of impoundment sludge,
onsite incineration or stockpiling of visibly
contaminated soil found beneath the sludge, and
treatment of water in the impoundments and
buildings. Based on new technical data and cost
information EPA has decided against using
incineration as treatment in OU1. This ROD
amends the original 1988 remedy for sludge
treatment. A future ROD will address the final
remedy for the site by providing for treatment of
contaminated soil, debris, and surface and
ground water, as OU2. The primary
contaminants of concern affecting the sludge are
VOCs including toluene and xylenes; other
organics including dioxin and PAHs; and metals
including lead.
SELECTED REMEDIAL ACTION:
The amended remedial action for this site
includes excavating and preparing 950 cubic
yards of solid sludge, 1,220 cubic yards of liquid
sludge, and 500 gallons of oil collected from the
sludge from temporary storage cells within the
impoundments area; and transporting sludge
and oil to a permitted recycling facility to
reclaim creosote for use at other wood treating
facilities, followed by offsite incineration of
recycler residues, and offsite disposal of
incinerator ash in a permitted landfill. The
estimated total cost for this remedial action
ranges from $2,058,200 to $2,191,000. O&M costs
are included in the capital costs because
treatment will occur offsite.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific sludge clean-up goals are
based on RCRA land disposal restrictions and
include lead 0.51 mg/1, toluene 28 mg/kg, and
xylenes 33 mg/kg.

CENTRAL CITY-CLEAR CREEK, CO
September 30,1991
SITE HISTORY/DESCRIPTION:
The Central City-Clear Creek site is an active
mining facility in Central City, Clear Creek and
Gilpin counties, Colorado. Land use in the area
is predominantly commercial and recreational,
and an artificial wetlands area is located onsite.
The site lies within the 400-square mile drainage
basin of Clear Creek, which serves as a drinking
water source for several municipalities. Gold
mining operations began onsite in 1859 and
portions of the site became some of the most
heavily mined areas of Colorado. Extraction of
surface ores led to an increase in the depth of
the mining and, consequently, drainage tunnels
were constructed to control water drainage
problems. Presently, six major mine drainage
tunnels are thought to be principal discharge
sources of acid mine water containing high
concentrations of metals to surface waters
including Clear Creek and its tributaries. In
addition, over 21 mine tailings piles with an
estimated total volume of over 2,000,000 cubic
yards at numerous locations throughout the site
are thought to be major sources of
contamination. In response to site
contamination, EPA has conducted three removal
actions since 1987. In 1987, EPA conducted a
removal action to prevent the collapse of a mine
waste pile. Also in 1987, EPA conducted a
second removal action, which involved
connecting three residences with private wells to
the municipal public water supply. In 1991, EPA
conducted a third removal action, which
involved removing uncontaminated mercury
from a small trailer. Because of the complexity
of the site, EPA divided the site into several
operable units (OUs) for remediation. A 1987
ROD addressed OU1 and provided for passive
treatment of acid mine water discharge from five
discharging tunnels: National, Gregory Incline,
Argo Tunnel, Big Five, and Quartz Hill tunnels.
A 1988 ROD addressed OU2 and provided for
the remediation of mine waste piles in the
immediate proximity of the five discharging
tunnels. This ROD supersedes the remedy
provided for OU1 in the 1987 ROD by including
active treatment of the Argo Tunnel and
delaying a decision on treating the discharges
from the Big Five, National and Quartz Hill
tunnels, and the Gregory Incline. EPA will
consider a subsequent ROD to address treatment
of the remaining onsite tunnels pending further
monitoring and treatability studies. The primary
contaminants of concern affecting the ground
water are metals including arsenic, cadmium,
chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing physical barriers for mine waste
piles (to reduce metals loading to surface water
and human health risks from ingestion or
inhalation of metals); treating discharges from
the Burleigh tunnel passively through the use of
man-made wetlands; treating discharges from
the Argo runnel actively along with ground
water pumped from the immediate area;
providing an alternate water supply where
needed; invoking an interim action waiver of
ARARs for discharges from the National, Quartz
Hill, and Big Five tunnels, and the Gregory
Incline, and invoking a technical impractical!ty
waiver for restoring ground water to MCLs;
collecting discharges from the National and
Quartz Hill tunnels, and Gregory Incline with
final disposition to be established pending
further monitoring and treatability studies; and
implementing institutional controls. The
estimated present worth cost for this remedial
action is $23,510,000, which includes an annual
O&M cost of $1,204,000 for 30 years.

SITE HISTORY/DESCRIPTION:
The Chemical Sales (New Location) (Operable
Unit 1) site is an active chemical sales and
storage facility in Commerce City, Adams and
Denver Counties, Colorado. Land use in the
area is predominantly industrial, and there are
six residences located on the northern portion of
the site. The site is bounded by Sand Creek to
the north and lies within the 100-year floodplain
of the creek. An estimated 30,000 people who
reside near the site use the alluvial aquifer as the
principal source of drinking water. Since 1976,
Chemical Sales (CS) has used the site to store
and sell organic chemicals and acids. Site
features include a warehouse and tank farm
including an associated system of above-ground
and underground storage tanks and pipelines.
Between 1985 and 1990, three onsite chemical
releases of hazardous substances into the soil
and ground water from the CS facility were
reported. In 1985, approximately 200 gallons of
methylene chloride were spilled into onsite soil
during a chemical transfer. The second release
was in 1986 when rainwater contaminated with
several VOCs was discharged into a nearby
drainage ditch. The third release occurred in
1990, when approximately 3,700 gallons of
methanol were spilled on the ground surface
near the CS tank farm. Several EPA
investigations confirmed the release of hazardous
substances into the ground water from the CS
Property. The site has been divided into three
operable units for remediation. This ROD
addresses remediation of soil and ground water
contamination south of Sand Creek, as OU1.
Future RODs will address other site
contamination including the ground water plume
and associated contamination (OU2), and
residential exposure to contaminated wells and
domestic water from the municipal water supply
(OU3). The primary contaminants of concern
affecting the soil and ground water are VOCs
including PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating contaminated onsite soil using vapor
extraction; treating air emissions with catalytic
oxidation; recirculating exhaust from the catalytic
oxidation system into the contaminated soil;
pumping and onsite treatment of ground water
in the source area and plume area using air
stripping, followed by reinjecting the treated
water from the source area wells and
reinfiltrating treated water from the plume area
through onsite discharge; monitoring ground
water, treated water, and air; providing public
notice of potential health threat from
contamination ground water; and implementing
institutional controls including ground water use
restrictions. The estimated cost for this remedial
action is $2,081,000. No O&M costs were
provided for this remedial action.
PERFORMANCE STANDARDS OR GOALS:

approximately 200 gallons of methylene chloride
were released during a chemical transfer second,
in 1986 VOC-contaminated rainwater was
discharged into a nearby drainage ditch. And
this in 1990, approximately 3,700 gallons of
methanol were spilled onto the the ground near
the CS tank farm. The site has been divided into
three operable units (OUs) for remediation. A
previous ROD addressed onsite soil and ground
water contamination as OU1. This ROD
addresses OU2, the VOC-contaminated ground
water plume, which is north of Sand Creek. A
subsequent ROD will address residential
exposure to the contaminated alluvial aquifer.
The primary contaminants of concern affecting
the ground water are VOCs including benzene,
PCE, and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for OU2 of this site
includes pumping and onsite treatment of
ground water using air stripping, followed by
onsite reinjection of treated water into the
aquifer; annual ground water monitoring; and
voluntary abandonment of bedrock wells. The
estimated present worth cost for this remedial
action is $2,420,000, which includes an annual
O&M cost of $223,000 for years 0-8 and $27,000
for years 8-20.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include

CHEMICAL SALES (NEW LOCATION) (OPERABLE UNIT 3), CO
June 27,1991
SITE HISTORY/DESCRIPTION:
The Chemical Sales (New Location) (Operable
Unit 3) site is an active chemical sales and
storage facility in Commerce City, Adams
County, Colorado. Land use in the area is
predominantly industrial. This area is part of a
4-square-mile area, which consists of single and
multifamily residences, small businesses,
municipal facilities, and agricultural and
undeveloped land. An estimated 30,000
residents near the site use the alluvial aquifer as
the principal source of drinking water. Since
1976, Chemical Sales (CS) has used the site to
store and sell a variety of organic chemicals and
acids. Onsite features include a warehouse, a
tank farm, and an associated system of
underground storage tanks and pipelines.
Between 1985 and 1990, three onsite chemical
releases of hazardous substances into the soil
and ground water from the CS facility were
documented. First, in 1985, approximately 200
gallons of methylene chloride were released
during an onsite chemical transfer. Second, in
1986, VOC-contaminated rainwater was
discharged into a nearby drainage ditch. And
third, in 1990, approximately 3,700 gallons of
methanol were spilled on the the ground surface
near the CS tank farm. EPA investigations
confirmed the release of hazardous substances
into ground water from the CS property. This
site has been divided into three operable units
(OUs) for remediation. Two previous 1991
RODs have addressed soil and ground water
contamination as OU1 and OU2. This ROD
addresses OUS, residential exposure to site
contaminants through domestic use of the
underlying alluvial aquifer. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, and
TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
connecting residences currently using alluvial
wells for domestic water supply to the South
Adams County Water Supply District
(SACWSD); installing home-activated carbon
units in homes not readily accessible to
SACWSD; implementing ground water
monitoring for benzene; and providing public
notification of the potential health threat from
the contaminated ground water. The estimated
present worth cost for this remedial action is
$157,000, which includes an annual O&M cost of
$5,520 for 30 years. Future costs for activated

HILL AIR FORCE BASE, UT
September 30,1991
SITE HISTORY/DESCRIPTION:
The 6,700-acre Hill Air Force Base (Hill AFB) site
is an active military facility situated between the
cities of Ogden and Salt Lake City, covering
portions of Davis and Weber Counties, Utah.
This ROD addresses part of operable unit 2
(OU2), which consists of two unlined disposal
trenches, seeps, and springs, and confined and
unconfined aquifers. Land use in the area is
mainly agricultural and residential. Both South
Weber and Hill AFB obtain drinking water from
deep wells in confined aquifers. Because the
base covers a large area, the Air Force has
grouped geographically adjacent contaminated
areas into seven OUs. From 1967 to 1975, Hill
AFB disposed of waste solvents and sludge from
degreasing operations in the onsite disposal
trenches. It is estimated that 100,000 to 1,000,000
gallons of TCE bottoms from the solvent
recovery unit, sludge from vapor degreasers, and
plating-tank sludge bottoms were disposed of in
these trenches. Federal investigations from 1983
to 1986 identified VOC contamination in onsite
and offsite ground water. As a result of these
investigations, Hill AFB began collection and
treatment of contaminated ground water from
seeps and springs in 1986. In addition, an
alternate water supply was provided to five
properties to prevent the use of contaminated
ground water from seeps and springs. This
ROD addresses the interim remediation of OU2
subsurface soil and ground water by removing
a DNAPL source and thus preventing
contaminants from reaching aquifers currently
used as drinking water sources. A subsequent
ROD will provide a final remedy for OU2 soil,
ground water, surface water, and air. The
primary contaminants of concern affecting the
soil and ground water are VOCs including PCE,
TCE, toluene, and xylenes.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes installing and maintaining a
source recovery system to remove DNAPL
contamination from the subsurface; pumping
DNAPL-contaminated ground water, with onsite
discharge to a pretreatment facility to separate
DNAPL from ground water using a steam
stripper; temporarily storing the DNAPL onsite
in steel tanks, followed by transporting the waste
offsite for incineration; installing a pipeline from
the site to the base Industrial Wastewater
Treatment Plant (IWTP); treating the pretreated
ground water at the IWTP using air stripping,
followed by carbon adsorption; discharging the
treated water offsite to a POTW; and monitoring
DNAPL collection and treatment during
remediation activities. The estimated present
worth cost for this remedial action is $3,710,000,
which includes an annual O&M cost of
$1,000,000 for 2 years.
PERFORMANCE STANDARDS OR GOALS:
Actual chemical-specific standards or goals will
be set in a future ROD.

ROCKY FLATS PLANT (USDOE), CO
January 25,1991
SITE HISTORY/DESCRIPTION:
The Rocky Eats Plant (USDOE) site is part of the
6,550-acre nuclear weapons research,
development, production, and plutonium
processing complex in Jefferson County,
Colorado. The plant is composed of the 450-acre
Rocky Flats Plant (RFP) security area and the
remaining buffer area. Land use in the area is
predominantly rural and agricultural with
several new residential areas under
development. This ROD addresses operable unit
2 (OU2), which includes the 903 Pad and Lip,
and Mound and East Trenches Areas, which are
located southeast of the RFP. The site lies within
the South Walnut Creek and Woman Creek
drainage basins. The South Walnut Creek Basin
and Woman Creek surface water serve as a
source of drinking water. Since 1951, the
Department of Energy (DOE) used the site for
manufacturing components for nuclear weapons,
processing plutonium, and fabricating,
machining, and assembling components from
metals. A number of past onsite storage and
disposal activities are potential sources of
contamination. From 1958 to 1967, drums
containing radioactively contaminated oils and
solvents were stored onsite, with some of the
drums corroding and leaking approximately
5,000 gallons of liquid into the soil. During a
clean-up and removal effort of the drum storage
area, winds distributed plutonium to the south
and east. Prior to 1968, sanitary sewage sludge
and flattened drums contaminated with uranium
and plutonium were disposed of in onsite
trenches, and drums of uranium-contaminated
oil were burned in onsite pits. During the 1950's
and 1960's, reactive metals including lithium,
and solvents were destroyed onsite. In addition,
various bottled gases were detoxified onsite
between 1982 and 1983. Current waste handling
Practices involve onsite and offsite recycling of
hazardous materials, and offsite disposal of solid
radioactive materials at another DOE facility.
DOE has conducted a number of investigations
that revealed VOCs, metals, and radionuclides
above background levels in soil, sediment,
ground water, and surface water. A 1969
clean-up action attempted to remove corroded
and leaking drums of radioactive waste from an
onsite area, remove contaminated soil, and cap
the soil. In 1970, approximately 1,405 drums
containing radioactive waste were removed and
disposed of offsite. A 1990 ROD addressed
contaminated ground water. This ROD provides
an interim remedy for contaminated South
Walnut Creek Basin surface waters as part of
OU2. The primary contaminants of concern
affecting the surface water are VOCs including
carbon tetrachloride, PCE, and TCE; and
radioactive materials.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes collecting surface water using
diversion; treating surface water using
precipitation and cross-flow membrane filtration
to remove suspended solids and radionuclides,
followed by liquid-phase activated carbon to
remove organic contaminants; discharging the
treated water onsite to South Walnut Creek;
conducting treatability studies; and monitoring
surface water. The estimated present worth cost
for this remedial action is $4,850,600, which
includes an annual O&M cost of $361,600.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific surface water clean-up goals
will be based on the most stringent of State and
Federal allowable limits as set forth in ARARs,
and will apply to the final remedial action.

ROCKY MOUNTAIN ARSENAL (OPERABLE UNIT 21), CO
June 6, 1991
SITE HISTORY/DESCRIPTION:
The Rocky Mountain Arsenal (RMA) (Operable
Unit 21) site comprises part of the 17,000-acre
RMA site, which is a former U.S. Army chemical
warfare and incendiary munitions manufacturing
and assembly plant in Adams County, Colorado.
From the 1950's until late 1969, the U.S. Army
used the RMA facility to produce the nerve
agent GB (isopropylmethyl-phosphono-
fluoridate). In addition, between 1947 and 1982,
private industries leased major portions of the
plant's facilities to manufacture various
insecticides and herbicides. From 1970 through
1982, U.S. Army facility operations have
primarily involved the destruction of chemical
warfare materials. Because final remediation of
the RMA site will take many years to complete,
13 interim response actions (IRAs) were
determined necessary prior to implementing the
final On-Post ROD. Operable Unit 21 (OU21),
the South Tank Farm Plume (STFP), is one of
several areas being addressed as part of the
Other Contaminated Sources IRA. The STFP is
located in the southern half of sections 1 and 2
of the RMA site. From 1947 to 1978, STF tanks
464A, 464B, and others were used intermittently
to store bicycloheptadiene (BCHPD) and
dicyclopentadiene (DCPD) bottoms generated
from pesticide manufacturing. In addition,
mixtures of BCHPD, DCPD, and fuel oil were
pumped onto the ground, or collected or buried
onsite during tank cleanings. From 1960 to 1963,
teakage of BCHPD/DCPD bottoms occurred
from a pipe connected to tank 464A, and
additional spills occurred in 1964 and 1978. The
e*act spill locations and amounts are generally
not known. Additionally, in 1948, a large spill of
benzene containing toluene and xylene
impurities occurred in the STF. A number of
U.S. Army investigations have revealed ground
water contamination originating from the areas
of light nonaqueous phase liquid (LNAPL)
located near tank 464A. Recent investigations
have shown that the STFP does not pose
significant risk to public health or the
environment, as originally suspected, because
data indicate that the plume will not migrate
into nearby Lake Ladora or Lake Derby prior to
implementation of the final remedy. In addition,
biodegradation of the plume may be occurring.
This ROD addresses interim management of
migration of the STFP and is consistent with the
Final Response Action. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, toluene, and
xylenes.
SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes performing one-time comprehensive
ground water monitoring throughout the STFP
to verify the extent and migration rate of STFP
constituents and the existence of conditions
conducive for biodegradation within the STFP;
and conducting annual ground water monitoring
including performing quarterly measurement of
STFP water levels. No cost information was
provided for this interim remedial action.

The Rocky Mountain Arsenal (RMA) (Operable
Unit 26) site comprises part of the 17,000-acre
RMA site, which is a former U.S. Army chemical
warfare and incendiary munitions manufacturing
and assembly plant in Adams County, Colorado.
From the 1950s until late 1969, the U.S. Army
used the RMA facility to produce the nerve

Because final remediation of the RMA site will
take many years to complete, 13 interim
response actions (IRAs) were determined
necessary prior to implementing the final
On-Post ROD. Operable unit 26 (OU26), which
is one of these 13 IRAs, is composed of the
piping and equipment in the buildings in the
North and South Plants at RMA. From 1987 to
1989, the U.S. Army surveyed and sampled the
former chemical process equipment and piping
in the North and South Plants. In 1990, the U.S.
Army decontaminated piping and equipment in
some buildings in the North Plant, and sampled
2,354 1-ton containers. This ROD addresses
contaminated piping and equipment in
numerous buildings in the North and South
Plants, and contaminated 1-ton containers. This
IRA will facilitate the final remedy for the
cleanup of chemical process buildings and
structures, by verifying the decontamination
status of chemical process piping, equipment,
and 1-ton containers, and decontaminating these
structures and 1-ton containers, as necessary, to
allow for reuse or disposal of the equipment and
piping. The primary contaminants of concern
affecting the debris and air are the chemical
agents GB (Agent GB, Sarin), HD (Agent
Mustard), L (Agent Lewisite), and VX (Agent
VX).
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
sampling to determine the level of
decontamination inside piping and equipment as
identified in the sampling operations in the

WASATCH CHEMICAL (LOT 6), UT
March 29,1991
SITE HISTORY/DESCRIPTION:
The 18-acre Wasatch Chemical (Lot 6) site is an
active chemical production, storage, and
distribution facility in Salt Lake City, Utah.
Land use in the area is predominantly industrial.
The site lies one-half mile east of the Jordan
River, within the center of the Jordan River
Valley. The site overlies a thick aquifer that is a
regional source of potable water. Surface water
run-off from the site is drained by a series of
ditches, which ultimately discharge to the Great
Salt Lake. From 1957 to 1986, Wasatch Chemical
Company and other tenants used the site for
production, packaging, storage, and distribution
of various chemical products including industrial
chemicals, acids, solvents, pesticides, and
fertilizers. Process wastes including dioxins,
were directed toward an onsite evaporation
pond, stored in 40 drums, and also discharged
directly in the ground and possibly into the Salt
Lake City sewer system. Noncompliance with
State and Federal hazardous waste storage
practices and disposal standards prompted a
number of the State investigations, which
revealed elevated levels of VOCs in onsite soil
and sludge, and PCE in ground water. In 1986,
as part of a removal action, EPA removed 40
drums and cylinders and other contaminated
materials offsite. This ROD addresses
contamination of onsite soil, sludge, and ground
water as a final remedy. The primary
contaminants of concern affecting the soil,
sludge, and ground water are VOCs including
PCE, TCE, toluene, and xylenes; and other
organics including pesticides, herbicides, and
dioxins.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating and consolidating 3,587 cubic yards of
contaminated soil and sludge and 650 gallons of
liquid waste in the former evaporation pond;
treating these materials onsite using in-situ
vitrification; excavating and land farming
1,111 cubic yards of hydrocarbon-contaminated
soil; sealing the surface of the site using asphalt
paving; pumping and onsite treatment of 20.4
million gallons of contaminated ground water
using air stripping; controlling air emissions with
carbon adsorption, if needed, followed by offsite
disposal of residuals; and implementing
institutional controls including deed and ground
water use restrictions. The estimated present
worth cost for this remedial action is $3,900,000,
which includes an estimated annual O&M cost of
$33,000 for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Soil clean-up goals are based on health-based
action levels and include PCE 103,000 ug/kg,
TCE 22,000 ug/kg, and dioxin <1 ug/kg (based
on RCRA Land Disposal Restrictions). Ground
water action levels are based on SDWA MCLs
and proposed MCLs, and include PCE 5 ug/1
(MCL) and TCE 5 ug/1 (MCL).
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented to prevent land and ground water
access and use at the site.

ADVANCED MICRO DEVICES 901 (SIGNETICS)
(TRW MICROWAVE), CA
September 11,1991
SITE HISTORY/DESCRIPTION:
The 3-acre Advanced Micro Devices (AMD) site
is an active semiconductor manufacturing facility
in Sunnyvale, Santa Clara County, California.
The site is part of a larger study area that
includes four operable units (OUs): the AMD
901 site, the Signetics site, the 1-acre TRW
Microwave site, and a 100-acre offsite
contaminated ground water plume. Land use in
the area is predominantly commercial and
industrial. Residential property lies to the north
and west of the main facilities and overlies
portions of the offsite ground water OU. Six
aquifers are associated with the study area
including a deeper aquifer confirmed only at the
TRW and Signetics sites. Currently, the
contaminated ground water is not used as a
drinking water supply, but the State considers
several of the aquifers to be potential drinking
water sources. From 1969 to the present, AMD
has used its portion of the study area for
manufacturing semiconductors using organic
solvents, acids, and metals. These substances
also were used in semiconductor manufacturing
at the Signetics and TRW sites from 1964 to the
present and from 1974 to 1986, respectively. As
a result of a leakage from the acid neutralization
system at the AMD site, a number of
investigations were conducted that revealed
extensive contamination of onsite soil and
ground water. Leakage from an underground
waste solvent storage tank at the Signetics site
and responses to an information questionnaire
regarding an underground tanks investigation at
the TRW site resulted in a number of
investigations that revealed extensive
contamination of soil and ground water. Several
initial remedial measures were conducted at the
AMD OU. During 1983 and 1984, acid
neutralization sumps and approximately
217 cubic yards of contaminated soil were
removed. From 1984 to 1988, remediation of
ground water was implemented using extraction
wells and dewatering sumps. Several initial
remedial measures also were conducted at the
Signetics OU. From 1982 to present, ground
water has been pumped from various site
locations and treated using air stripping and
carbon adsorption, followed by air stripping to
control off-gases and reuse of the treated water
in industrial processes. Contaminated soil has
been removed from three separate locations,
including 4,720 cubic yards of soil from a waste
solvent storage tank area in 1983. In 1989, three
vapor extraction wells were installed to treat
contaminated soil. Several initial remedial
measures also have been conducted at the TRW
OU. From 1983 to 1984, an underground waste
solvent storage tank and 120 cubic yards of
onsite contaminated soil were removed. From
1984 to present, ground water has been pumped
and treated using air stripping, followed by
onsite discharge to surface water. In addition,
two ground water extraction systems pump
contaminated ground water from the 100-acre
offsite plume. The extracted water is treated at
a neighboring AMD facility using air stripping,
followed by liquid phase granular activated
carbon polisher and onsite discharge to surface
water, or reuse by the facility. This ROD
collectively addresses final remediation of soil
and ground water in the four separate OUs
within the study area. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE and TCE;
and other organics.
SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
separate remedies for the four different OUs of
the study area. The remedy for the AMD OU
includes excavating 37 cubic yards of onsite
contaminated soil, followed by offsite
incineration and/or disposal, and backfilling the

excavation with clean soil; and continuing onsite
pumping and treatment of ground water using
air stripping and carbon adsorption of off-gases,
followed by reuse of the treated water. The
remedy for the Signetics OU includes expanding
the onsite soil vapor extraction system and
continuing onsite pumping and treatment of
ground water using air stripping, followed by
aqueous-phase carbon polishing, reuse of the
treated water, and vapor-phase carbon treatment
of the effluent air stream. The remedy for the
TRW OU includes continuing onsite pumping
and treatment of ground water using air
stripping, followed by onsite discharge of treated
water to surface water. The remedy for the
offsite ground water OU includes continuing and
expanding the pumping and treatment system
for contaminated ground water using air
stripping and aqueous-phase carbon adsorption,
followed by reuse of the treated water or onsite
discharge to surface water, and offsite
regeneration of spent carbon. Each OU also will
involve continued ground water monitoring, and
implementing institutional controls including
deed and ground water use restrictions. The
estimated present worth cost for the remedial
action for all OUs is $11,900,000, which includes
an estimated O&M cost of $225,000 for the AMD
OU; $236,000 for the Signetics OU; and $255,000
for the offsite ground water OU. No annual
O&M cost was provided for the TRW OU.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals have been

ADVANCED MICRO DEVICES #915, CA
August 26,1991
SITE HISTORY/DESCRIPTION:
The Advanced Micro Devices (AMD) #915 site is
an active semiconductor manufacturing facility
in Santa Clara County, California. The site
consists of approximately 5 acres and contains
three physical structures, the largest of which is
a 116,000-square-feet building known as AMD
915. The site is in the Santa Clara Valley, and
the facility lies within an industrial park
bordered by residential areas- Ground water
from this basin provides up to 50 percent of the
municipal drinking water for 1.4 million
residents of the Santa Clara Valley. The site
overlies three aquifers, one of which is known as
the B aquifer, which is approximately 20 to 100
feet below the surface. AMD #915 was built in
1974, and onsite manufacturing processes have
involved the use of solvents, caustics, and acids.
Eleven chemical storage or treatment areas have
been documented at the AMD #915 facility
including three underground acid neutralization
systems, two above-ground drum storage areas,
and six underground tank complexes. Two of
the acid neutralization systems remain in
operation, as well as one drum storage area, and
two tank complexes. Records indicate that
solvent wastes and other materials were stored
in underground tanks, and as many as 28
separate underground tanks may have been in
service at various times. In 1981, site
investigations discovered soil contamination
during a planned underground storage tank
removal. Two leaking underground tanks were
identified, and 7,000 cubic yards of contaminated
soil were removed. The majority of these tanks
now have been removed from service or
replaced. In 1982, ground water contamination
also was addressed and found to be limited to
the B aquifer. Additional offsite sources of
ground water contamination may have a
significant effect on the AMD #915 site including
commingling of ground water contamination.
The most notable of these are Advanced Micro
Devices 901/902 facilities, Signetics, and FEI
Microwave. Two interim remedial actions for
soil were completed during 1981 and 1982,
including offsite removal and disposal of a waste
solvent tank, and the removal of one acid
neutralization system and 5,500 cubic yards of
soil. In 1982, ground water pumping and
treatment using air stripping and carbon
adsorption began onsite using existing building
dewatering sumps. This was supplemented with
the installation of a series of wells during 1982
and 1988. This ROD addresses remediation of
onsite contaminated ground water. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, TCE,
toluene, and xylenes; other organics; and metals
including arsenic and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continuing the operation of eight existing ground
water extraction wells; and treating contaminated
ground water onsite using air stripping and
carbon adsorption, followed by discharge of the
treated water onsite to surface water. The
estimated present worth cost for this remedial
action is $2,100,000. This figure represents the
O&M costs for 30 years since the system is
already in place as an interim measure and no
additional capital costs are required.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up standards are based on
the more stringent of Federal or State MCLs for
drinking water. Chemical-specific goals for
ground water include PCE 5 ug/1 (MCL), and
TCE 5 ug/1 (MCL).

ATLAS ASBESTOS MINE, CA
February 14,1991
SITE HISTORY/DESCRIPTION:
The 450-acre Atlas Mine Area is part of the Atlas
Asbestos Mine site in Fresno County, California.
The site consists of four geographically distinct
areas (the Atlas Mine Area, the Clear Creek
Management Area (CCMA), the Ponding Basin
of the California Aqueduct, and the City of
Coalinga). The Atlas Mine Area is on rural land
owned by the Federal government and private
parties, and surrounding land is used for
mining, ranching, farming, and recreation. The
Mine Area includes three open pit asbestos mine
surfaces, stockpiles of asbestos waste material, an
abandoned mill building, a settling pond, and
debris. Construction of an asbestos mill at the
Atlas Mine began in 1962, and onsite asbestos
mining and milling activities occurred from 1967
to 1979. Approximately 3 million cubic yards of
asbestos ore and asbestos mill tailings from
onsite operations were bulldozed into piles
adjacent to the mill building. In 1976 and 1980,
the Atlas Mine was cited for violating asbestos
emissions standards. In early 1980, after
detecting elevated levels of asbestos in water
samples from the California Aqueduct, the State
concluded that additional corrective measures
were necessary to prevent mine- and
mill-generated asbestos from entering the
drainage basins. Further State investigations
identified high concentrations of asbestos in the
Mine Area soil, surface water, and air. A 1989
ROD for the City of Coalinga Operable Unit
addressed cleanup of asbestos-contaminated soil
in Coalinga, California by burying the
contaminated material in a waste management
unit with an impermeable cap. This ROD is
designed to control the release of asbestos from
the Mine Area. No actions are proposed at this
time for the CCMA or the Ponding Basin of the
California Aqueduct. In 1992, EPA will evaluate
the Department of Interior Bureau of Land
Management's revised land use plan for CCMA
to determine if the plan is adequate to minimize
airborne asbestos emissions, and the U.S. Bureau
of Reclamation and California Department of
Waste Resources actions to minimize airborne
emissions from the Ponding Basin to determine
if further action is necessary. The primary
contaminant of concern affecting the soil,
sediment, debris, surface water, and air is
asbestos, an inorganic.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
paving the road through the Mine Area or
implementing an appropriate road maintenance
alternative; constructing stream diversions,
sediment trapping dams, and other slope
stabilization elements; instituting a verification
sampling plan involving surface water modeling
and surface water and stream bed sampling, as
necessary; conducting a revegetation pilot
project, and implementing revegetation if found
to be technically feasible and cost-effective;
dismantling the mill building with offsite
disposal along with other debris from the Mine
Area; and implementing institutional controls
including deed and land use restrictions, and site
access restrictions such as fencing. The
estimated present worth cost for this remedial
action is $4,286,000, which includes an annual
O&M cost of $19,000.
PERFORMANCE STANDARDS OR GOALS:
All diversion and drainag^ facilities will be
designed and constructed to accommodate the
anticipated volume of precipitation and peak
flows from surface runoff in a 25-year, 24 hour
storm. All tailings will be protected from
100-year peak stream flows. Quantification of
risk reduction is difficult because asbestos from
natural and disturbed areas will continue to
enter the surface water; however, a verification
sampling plan will be implemented to confirm
that an appropriate reduction in asbestos
transport is achieved.

CTS PRINTEX, CA
June 28,1991
SITE HISTORY/DESCRIPTION:
The CTS Printex site is an inactive printed circuit
board manufacturing facility in Mountain View,
Santa Clara County, California. Land
surrounding the site is used for industrial,
commercial, residential, and agricultural
purposes. The site overlies two major
water-yielding zones, a shallow and deep
aquifer, which are suspected to be hydraulically
continuous. Historical ground water use in the
area surrounding the site includes private
water-supply wells for homes and agriculture
prior to the construction of public water and
sewer connections in 1984. Site features include
a flammable materials storage shed area, an
industrial wastewater sump used to neutralize
and discharge waste to the POTW, a "wet floor"
building used for both wet and dry
manufacturing processes, a materials and waste
storage warehouse, and various office buildings.
From 1981 to 1985, the CTS Printex site
manufactured printed circuit boards at its onsite
facilities. Site investigations by CTS Printex in
1985 established that the "wet floor" building and
the wastewater sump areas were the sources of
onsite soil and ground water contamination, and
that the release of contaminants was attributed to
deterioration of the concrete bases. In 1986, the
State certified closure of the former CTS facility.
In 1987, the State required CTS to implement the
following interim remedial actions for soil and
ground water: destroying and removing
contaminated onsite structures, removing
residual metals sludge and process debris from
the site, hydroblasting interior areas of structures
exposed to contaminants, excavating the sump
and contaminated soil, and installing and
operating a ground water extraction system.
This ROD addresses contaminated onsite ground
water. The primary contaminants of concern
affecting the ground water are VOCs including
benzene, PCE, TCE, and toluene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continuing the current ground water extraction
system, including discharging the untreated
water to the sanitary sewer for offsite treatment
at the POTW; and conducting ground water
monitoring. Passive air stripping is created by
passing water through the sewer collection
system and through the sewage treatment plant.
The estimated present worth cost for this
remedial action is $786,000, which includes an
estimated O&M cost of $104,700 for 15 years.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals are based on the
more stringent of Federal MCLs or non-zero
MCLGs, or State MCLs. Chemical-specific goals
include benzene 1 ug/1 (State), PCE 5 ug/1
(MCL), TCE 5 ug/1 (MCL), and toluene 100 ug/1
(State). Action-specific goals include compliance
with the City of Mountain View's discharge
requirement for the sanitary sewer, which is total
organics equal to 1 ug/1 at the point of
discharge.

CASTLE AIR FORCE BASE, CA
August 12,1991
SITE HISTORY/DESCRIPTION:
The 2,777-acre Castle Air Force Base is a
Strategic Air Command training base 6 miles
northwest of the City of Merced in Merced
County, California. Land use in the area is
predominantly agricultural. Several irrigation
canals and laterals are located within 1 mile of
the base including Canal Creek, which borders
the base on its southwest boundary and receives
runoff from the base and irrigated land
downstream. At least 20 agricultural wells are
located within 3 to 4 miles of the site, and a
number of residential and municipal wells are
located within 2 miles of the site. Since 1941, the
site has been used as a military air training base.
Fire training activities, as well as aircraft and jet
engine maintenance activities including metal
plating and processing, have occurred onsite.
Both processes involve the use of fuels, solvents,
and chemicals and have generated municipal
and chemical wastes. During routine well
sampling, the State identified elevated TCE
concentrations in ground water in the shallow
aquifer beneath and south of the site. In 1984,
the base was required not only to implement
remedial measures to correct this identified
contamination but also to prevent future ground
water degradation from waste discharges. The
site has been divided into operable units (OUs)
for remediation. This ROD provides an interim
remedy for the main TCE plume, as OU1.
Future RODs will address remaining soil and
ground water contamination. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, and
TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this interim
remedy includes onsite pumping and treatment
of ground water using air stripping, followed by
natural biological enhancement to accelerate the
release and degradation of hazardous
constituents in the saturated zone; reinjecting the
treated ground water onsite to maintain
hydraulic control and avoid depletion of the
aquifer; treating emissions from the air stripping
process using granular activated carbon; and
treating the emissions abatement unit by onsite
steam regeneration, and disposing of the liquid
condensate offsite. The estimated present worth
cost for this remedial action is $28,445,000, which
includes an annual O&M cost of $2,744,000.
PERFORMANCE STANDARDS OR GOALS:
Ground water clean-up goals based on MCLs
and risk levels will be established in a

FMC (FRESNO PLANT), CA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 17-acre FMC (Fresno Plant) site is an active
pesticide manufacturing facility in Fresno,
California. Surrounding land use is primarily
industrial, but several residential areas are
within 1 kilometer of the site. The site overlies
two unconsolidated sand zones that are a
potential source of ground water, and have been
contaminated by site operations. Since 1931,
various agricultural product operations have
been conducted onsite including sulfur
processing, and fertilizer and pesticide
manufacturing. Wastewater from liquid
pesticide formulation was discharged to a
4.92-acre area of the site via a trench during the
1960's and 1970's. From 1963 until 1974,
wastewater from oil drum cleaning operations
was stored in an above-ground tank and was
sprayed on a concrete evaporation slab in an oil
drum yard. A former disposal pond area was
used for the disposal of fertilizer process wastes
from 1967 to 1972. From 1972 until 1983, a
wastewater evaporation pond was used for the
discharge of wastewater, including oil drum
washing rinsate. From 1976 until 1988, a
rainwater percolation pond was used to collect
surface run-off from non-production areas of the
site. These waste disposal practices have led to
contamination of onsite soil and ground water.
In 1980, FMC excavated a portion of the
contaminated soil in the oil drum yard. In 1983,
discharge to the wastewater evaporation pond
was discontinued. In 1985,1,500 cubic yards of
contaminated soil were excavated from the waste
pond. In 1989, this pond was lined with a
synthetic liner. Investigations by FMC under
EPA oversight from 1989 to 1991 characterized
and quantified site contamination, affected
media, and probable source areas. This ROD
provides for remediation of onsite source areas
and restoration of ground water as a final
remedy. The primary contaminants of concern
affecting the soil and ground water are
organochlorine and organophosphorous
pesticides although VOCs including PCE, TCE,
toluene, and xylenes; other organics including
dioxin, PAHs, and phenols; and metals including
arsenic, chromium, and lead are also present.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating approximately 25,000 cubic yards of
contaminated soil from onsite source areas, and
treating the soil using soil washing and
stabilization technologies; backfilling the
excavated areas with treated soil; treating soil
wash water using carbon adsorption; capping
unpaved and excavated areas including the
4.92-acre wastewater evaporation pond, oil drum
yard, and percolation pond; onsite pumping and
treatment of ground water using filtration, air
stripping, and carbon adsorption; reinjecting or
reusing the treated ground water onsite;
providing an alternate water supply to onsite or
offsite well users, if necessary, to eliminate
adverse affects to ground water treatment;
monitoring ground water; and implementing
institutional controls including deed, land, and
ground water use restrictions. The estimated
present worth cost for this remedial action is
$17,310,681, which includes an annual O&M cost
of $445,163 for 30 years.
PERFORMANCE STANDARDS OR GOALS;
Clean-up standards for soil are based on a
carcinogenic risk level of 10"4 and an HI=1.
However, when combined with capping and
institutional controls, the selected soil remedy
attains a 10'6 carcinogenic risk level. Ground
water clean-up standards are based on the more
stringent of Federal or State MCLs or non-zero
MCLGs. If these standards do not exist, State
Action Levels, site-specific Health-Based Levels,
or Quantification Limits will be used.

INDIAN BEND WASH AREA (OPERABLE UNITS 1, 4, 5, 6), AZ
September 12,1991
SITE HISTORY/DESCRIPTION:
The Indian Bend Wash Area site is an active
electronics manufacturing and metal plating
facility located in the Cities of Scottsdale and
Tempe, Maricopa County, Arizona, The site
consists of two study areas, the North Indian
Bend Wash (NIBW) and South Indian Bend
Wash (SIBW), both of which contain portions
that lie in the 100-year floodplain of the IBW.
The NIBW area is the focus of this ROD and
consists of four operable units; 1, 4, 5, and 6,
Land use within the 10-square-mile NIBW study
area is mainly residential, commercial/industrial,
and developed open space (parks and golf
courses). In addition, the Salt River
Pima-Maricopa Indian Community maintains a
portion of NIBW as Cropland. The Indian Bend
Wash provides the major surface water drainage
for the NIBW area. Since 1950, various
electronics manufacturing and metal plating
facilities, as well as other industries, have been
active at NIBW. Onsite operations have
included the use and disposal of organic
solvents. During operations, waste solvents and
waslewater containing solvents were released
from solvent storage tanks and pipes directly to
dry wells, surface pits, ponds, lagoons, and the
ground surface. In 1981, the State conducted
well sampling and identified VOC contamination
in several municipal supply wells. EPA
investigations have concluded that the methods
used for solvent disposal led to soil
contamination, which in turn acted as a source of
contamination for underlying alluvial units. A
1988 ROD provided for remediation of the
middle and deep alluvial units at NIBW. This
ROD addresses contamination in the vadose
zone and in the upper alluvial unit within the
NIBW area. However, because the vadose zone
overlies the upper alluvial unit, which overlies
the middle and deep alluvial units, remedial
actions documented in this ROD are dependent
upon successful completion of the 1988 ROD.
The primary contaminants of concern affecting
the soil and shallow ground water are VOCs
including benzene, PCE, TCE, and toluene; other
organics; and metals including arsenic,
chromium, and lead. EPA has designated 13
areas at NIBW for potential contamination in the
vadose zone. Twelve of these areas are
designated by number. The 13th area is in the
vicinity of several City of Scottsdale ground
water supply wells.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing a soil vapor extraction system for
Areas 7 and 8 consisting of soil vapor extraction
wells, a manifold collection system, a vacuum
pump, and a vapor-phase carbon adsorption
system; installing additional soil vapor
monitoring wells to continue investigations in
Areas 3, 5, 6,9,11, and 12 with either soil vapor
extraction or no further action remedies as
needed; conducting no further action for Areas
1, 2, 4, 10, and the City of Scottsdale wells; and
ground water monitoring in the upper alluvial
unit. The estimated present worth cost for this
remedial action is a minimum of $21,576,000,
depending upon the need for soil vapor
extraction in Areas 3, 5, 6, 9, 11, and 12, which
includes an annual O&M co&t of at least $935,000
for 30 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil and ground water criteria
are based on the more stringent of State water
quality standards, Federal MCLs, or non-zero

MESA AREA GROUND WATER CONTAMINATION, AZ
September 27,1991
SITE HISTORY/DESCRIPTION:
The 80-acre Mesa Area Ground Water
Contamination site is a semiconductor
manufacturing facility in Mesa, Maricopa
County, Arizona. Land use in the area is
predominantly industrial and residential. The
site overlies two aquifers: a Lower Alluvial
Aquifer (LAA), which is used by the residents of
Mesa as a drinking water source, and an Upper
Alluvial Aquifer (UAA). Since 1966, Motorola,
Inc., has used the site for the production of
semiconductors and the storage of chemicals in
an underground storage system. Onsite
manufacturing processes involve the use of
solvents, acids, and bases. In 1983, Motorola
identified VOCs including TCE, in ground water
originating from the LAA. Subsequent
investigations by Motorola revealed high levels
of VOC-contaminated soil in the main chemical
handling area, and VOC and chromium
contamination in the UAA. From 1983 to 1987,
Motorola performed a partial closure of the
underground waste solvent storage system under
RCRA authority. In 1984, Motorola installed
ground water monitoring wells, later converted
these into extraction wells, and pumped
contaminated ground water from the UAA.
Since 1987, as a result of Motorola's actions,
contamination levels have been consistently
below MCLs. However, by 1991, the
contaminated ground water plume had migrated
to over 1 mile southeast of the site. In 1991, EPA
dropped the Mesa Ground Water Contamination
site from the NPL and referred the site to the
RCRA program because the site is a RCRA
facility, the ground water contamination is solely
from the Motorola facility, and no public
drinking water supply wells have been
contaminated. This action will be implemented
by the PRP under State supervision, and
incorporated as a component of the Corrective
Action Plan under RCRA. This ROD documents
final remediation of contaminated soil and
ground water. The primary contaminants of
concern affecting the soil and ground water are
VOCs including PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating shallow onsite soil using soil vapor
extraction, controlling VOC emissions using
carbon adsorption, followed by offsite disposal
of carbon residuals; onsite and offsite pumping
of contaminated ground water; treating the
ground water onsite using vacuum
degasification, followed by carbon adsorption to
remove VOCs; discharging the treated water
from the degasifier to the deionized water
treatment plant for reuse in manufacturing and
other facility processes; disposing of remaining
wastewater at a POTW; and rehabilitating two
deep industrial ground water supply wells to
prevent them from acting as conduits for
contaminant plume migration from the upper to
the lower aquifer. The estimated present worth
cost for this remedial action is $7,144,000, which
includes an annual O&M cost of $581,000 for 13
years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based

manufacturing facility and a magnetic bubble
production and testing facility in Santa Clara,
Santa Clara County, California. Land use in the
area is predominantly industrial, although
approximately 300,000 people reside within a
3-mile radius of the site. In addition, the site
overlies two shallow aquifers zones, which in
turn, overlie the Santa Clara Valley ground
water basin, the primary drinking water source
for the 1.4 million residents of the Santa Clara
Valley. From 1985 to 1986, Micro Storage
Corporation (MSC) researched, developed, and
manufactured microcomputer disk drives.
Chemicals used onsite were stored in an external
shaded storage area in 55-gallon drums. From
1978 to 1987, Intel Magnetics (IM), a magnetic
bubble production and testing facility, operated
both an underground solvent tank used to store
waste solvents, and an inorganic acid
neutralization system. As a result of possible
improper storage procedures at both facilities, a
number of State and EPA investigations
identified VOCs including benzene, TCE, and
TCA, and other organics in the ground water
aquifer beneath the site. Interim remedial
measures have included: extracting contaminated
ground water at both sites; removing all
chemicals stored on the combined MSC/IM site;
and replacing the underground storage tank and
excavating contaminated soil at the IM site.
Treated ground water is discharged to a storm
sewage system tributary of nearby Calabazas
Creek. This ROD addresses ground water
contaminated by past facility operations. The
primary contaminants of concern affecting the
ground water are VOCs including benzene, PCE,
TCE, and toluene; and other organics.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continuing ground water extraction and
treatment with carbon adsorption until clean-up
standards are achieved in all combined MSC/IM
site monitoring wells; installing and sampling a
minimum of two new monitoring wells;
hydraulically contain the entire 93,000 cubic
yards ground water plume above clean-up
standards; maintaining hydraulic control to
prohibit the further vertical and horizontal
migration of the ground water pollution;
quarterly ground water monitoring at the
combined MSC/IM site during the clean-up
period; treating the extracted ground water with
an existing carbon absorption system;
discharging the treated ground water onsite to
Calabazas Creek; and implementing deed
restrictions onsite. The estimated present worth
O&M cost for this remedial action ranges from
$630,000 to $1,100,000 for 10 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on the more stringent of Federal and
State MCLs standards, and include benzene
1 ug/1, PCE 5 ug/1, TCE 5 ug/1, and toluene
100 ug/1.
INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prohibit
the use of onsite shallow ground water and
control other subsurface activities.

SITE HISTORY/DESCRIPTION:
The Monolithic Memories (MM) site is a former
semiconductor manufacturing facility located in
Sunnyvale and Santa Clara, California. Land
surrounding the site is used for commercial and
light industrial purposes. The site lies within the
confined area of the Santa Clara Valley ground
water basin, which consists of various upper and
lower aquifer zones. Ground water from this
basin provides up to 50 percent of the municipal
drinking water for Santa Clara Valley residents.
Remediation of the MM site has been combined
with another National Priorities List (NPL) site.
National Semiconductor (NSC), because both
sites contribute to the same ground water
contamination problem. The combined
remediation has been divided into two operable
units (OUs). This ROD addresses GUI, which
consists of three subunits. Subunit 1 includes
the 60-acre NSC facility, which contains more
than 20 buildings used for administrative offices,
laboratories, and semiconductor manufacturing;
and the 10-acre United Technology Corporation
facility, which was used to develop and test
rocket propellants. Subunit 2 includes the MM
facility, currently owned by Advanced Micro
Devices, and consists of buildings used for office
space and semiconductor production facilities.
Subunit 3 consists of the areas downgradient
from Subunits 1 and 2 and extends to the
leading edge of the contaminant plume.
Semiconductor manufacturing activities took
place onsite at NSC beginning in 1967, and at
MM in 1970, and continued until 1989. Virgin
solvents and acids used in semiconductor
manufacturing processes were stored in
above-ground tanks and storage drums. Waste
solvents were stored in underground and
above-ground tanks, and acid wastes were
treated in underground and above-ground tanks
or underground neutralization sumps. In 1982,
NSC and MM conducted preliminary
assessments of soil and ground water near
underground storage tanks and sumps, in
response to a state-initiated storage tank leak
detection program. As a result, both NSC and
MM removed tanks, sumps, and soil from areas
containing elevated concentrations of solvents.
In addition, in 1984 and 1986, NSC installed
offsite and onsite ground water extraction
systems, and MM installed onsite extraction
systems in 1986 and 1988. This ROD addresses
remediation of contaminated soil on the facility
property and ground water in the upper aquifer
zone as OU1. OU2 will address remaining soil
and ground water problems associated with the
western portion of the ground water
contaminant plume. The primary contaminants
of concern affecting the soil and ground water
are VOCs including benzene, PCE, TCE, toluene,
and xylenes; and other organics including PAHs
and phenols.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating contaminated soil in Subunits 1 and 2
onsite using soil vapor extraction, with carbon
adsorption to control emissions, if required;
excavating and surface aeration of contaminated
soil, if necessary; pumping and onsite treatment
of contaminated ground water by expanding the
existing extraction system and adding an ozone
oxidation treatment system to the current air
stripper treatment systems; controlling air
emissions from the air strippers using carbon
treatment, if necessary; discharging the treated
ground water onsite to storm sewers; monitoring
ground water; and implementing institutional
controls including deed restrictions. The
estimated present worth cost for this remedial
action is $8,400,000, which includes a 30-year
operation period. O&M costs were not
provided.

SIGNETICS (ADVANCED MICRO DEVICES 901)
(TRW MICROWAVE), CA
September 11,1991
SITE HISTORY/DESCRIPTION:
The Signetics site is an active semiconductor
manufacturing facility in Sunnyvale, Santa Clara
County, California. The site is part of a larger
study area that includes four operable units
(OUs): the Signetics site, the 3-acre Advanced
Micro Devices (AMD) 901 site, the 1-acre TRW
Microwave site, and a 100-acre offsite
contaminated ground water plume. Land use in
the area is predominantly commercial and
industrial. Residential property lies to the north
and west of the main facilities and overlies
portions of the offsite ground water OU. Six
aquifers are associated with the study area
including a deeper aquifer confirmed only at the
TRW and Signetics sites. Currently, the
contaminated ground water is not used as a
drinking water supply, but the State considers
several of the aquifers to be potential drinking
water sources. From 1964 to the present,
Signetics used its portion of the study area for
manufacturing semiconductors with organic
solvents, acids, and metals. These substances
also were used in semiconductor manufacturing
at the AMD and TRW sites from 1969 to the
present and from 1974 to 1986, respectively. As
a result of a leakage from an underground waste
solvent storage tank at the Signetics site, a
number of investigations were conducted that
revealed extensive contamination of onsite soil
and ground water. Leakage from the acid
neutralization system at AMD and responses to
an information questionnaire regarding an
underground tanks investigation at TRW
resulted in a number of investigations that also
revealed extensive contamination of onsite soil
and ground water at both of these sites. Several
initial remedial measures were conducted at the
Signetics OU. From 1982 to present, ground
water has been pumped from various site
locations and treated using air stripping and
carbon adsorption, followed by air stripping to
control off-gases and reuse of the treated water
in industrial processes. Contaminated soil has
been removed from three separate locations,
including 4,720 cubic yards of soil from a waste
solvent storage tank area in 1983. In 1989, three
vapor extraction wells were installed to treat
contaminated soil. Several initial remedial
measures also have been conducted at the AMD
OU. In 1983 and 1984, acid neutralization sumps
and about 217 cubic yards of contaminated soil
were removed. From 1984 to 1988, remediation
of ground water was implemented using
extraction wells and dewatering sumps. Several
initial remedial measures also have been
conducted at the TRW OU. From 1983 to 1984,
an underground waste solvent storage tank and
120 cubic yards of onsite contaminated soil were
removed. From 1984 to present, ground water
has been pumped and treated using air
stripping, followed by onsite discharge to surface
water. In addition, two ground water extraction
systems pump contaminated ground water from
the 100-acre offsite plume. The extracted water
is treated at a neighboring AMD facility using
air stripping, followed by liquid phase granular
activated carbon polisher , with onsite discharge
to surface water or reuse by the facility. This
ROD collectively addresses final remediation of
soil and ground water in the four separate OUs
within the study area. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
separate remedies for the four different OUs.
The remedy for the Signetics OU includes
expanding the onsite soil vapor extraction
system; and continuing onsite pumping and
treatment of ground water using air stripping,
followed by aqueous-phase carbon polishing,
reuse of the treated water, and vapor-phase
carbon treatment of the effluent air stream. The
remedy for the AMD OU includes excavating 37

by offsite incineration and/or disposal, and
backfilling the excavation with clean soil;
continuing onsite pumping and treatment of
ground water using air stripping and carbon
adsorption of off-gases, followed by reuse of the
treated water. The remedy for the TRW OU
includes continuing onsite pumping and
treatment of ground water using air stripping,
followed by onsite discharge of treated water to
surface water. The remedy for the offsite
ground water OU includes continuing and
expanding the pumping and treatment system
for contaminated ground water using air
stripping and aqueous-phase carbon adsorption,
followed by reuse of the treated water or onsite
discharge to surface water, and offsite
regeneration of spent carbon. Each OU also will
involve continued ground water monitoring, and
implementing institutional controls including
deed and ground water use restrictions. The
estimated present worth cost for the remedial
action for all OUs is $11,900,000, which includes
an estimated annual O&M cost of $236,000 for
the Signetics OU; $225,000 for the AMD OU; and
$255,000 for the offsite ground water OU. No
annual O&M cost was provided for the TRW
OU.

SITE HISTORY/DESCRIPTION:
The 35-acre Sola Optical site is an active
ophthalmic lens manufacturing facility in
southern Sonoma County, California. Land use
in the surrounding area is mixed residential,
manufacturing, commercial, and undeveloped.
Adobe Creek is located 1,500 feet west of an
onsite building. The City of Petaluma utilizes an
unconfined aquifer, which underlies the site, as
a drinking water source. In 1982, Sola identified
low levels of solvents in onsite ground water
near six underground solvent storage tanks used
to store TCA, acetone, and methanol. In 1983,
the San Francisco Regional Water Quality
Control Board (SFRWQCB) directed Sola to
investigate ground water contamination at the
site. In 1985, Sola independently excavated and
removed the underground tanks along with the
gravel backfill and 3 to 5 feet of native soil from
the sides and bottom of the excavation. In 1987,
the SFRWQCB ordered Sola to construct a
ground water extraction and treatment system
and, in 1988, the treatment system began
pumping and treating ground water using
granulated activated carbon to remove VOC
contamination, followed by discharging the
treated ground water under permit to Adobe
creek. This ROD provides a final remedy to
restore ground water to its beneficial use. The
primary contaminants of concern affecting the
ground water are VOCs.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing additional extraction wells onsite;
continuing pumping and treatment of ground
water using the existing granulated activated
carbon adsorption system, followed by
discharging the treated water onsite to surface

SOUTH BAY ASBESTOS AREA (AMENDMENT), CA
June 26,1991
SITE HISTORY/DESCRIPTION:
The 550-acre South Bay Asbestos Area site
consists of a ring levee in Alviso, San Jose,
California. Land use in the area is mixed
residential, commercial, light industrial, and
agricultural. A 300-acre wetlands area is located
adjacent to the site and is partially covered by
the levee. The ring levee was constructed by the
City of San Jose as an emergency measure
during a flood in March 1983, but a number of
subsequent EPA investigations determined that
the levee soil was comprised of 40 percent
asbestos. In 1986 and 1987, EPA conducted
several emergency response actions to reduce
asbestos exposure around the site including the
removal of an asbestos pile, paving and covering
local roads and lots, and spraying the levee with
a dust-suppressing polymer. A 1988 ROD
provided for installation of a vegetated soil cover
over the levee. A subsequent 1989 ROD
addressed the remediation of portions of the site
not previously addressed and provided for
paving of contaminated truck yards, monthly
wet sweeping of streets, removal of asbestos
waste debris, cover requirements, inspections,
deed restrictions on landfills, and site
maintenance and monitoring. This ROD amends
the 1988 ROD for the asbestos-contaminated soil
in the ring levee and surrounding area. The
primary contaminant of concern affecting the soil
is asbestos, an inorganic.
SELECTED REMEDIAL ACTION:
The selected amended remedial action for this
site includes excavating and disposing offsite
25,000 cubic yards of asbestos-contaminated
levee soil; restoring any wetlands areas located
under the levee, or which were disturbed by the
excavation; and conducting soil sampling. The

SITE HISTORY/DESCRIPTION:
The Spectra-Physics site is composed of two
Superfund sites: the Spectra-Physics site, a laser
and related components manufacturing facility,
and the Teledyne Semiconductor site, a
semiconductor manufacturing facility, as well as
offsite areas associated with a contaminated
ground water plume in Mountain View,
California. Land use in the area is
predominantly commercial and industrial. The
site is bordered by Permanente Creek to the west
and a landfill dewatering trench to the north.
Prior to the construction of public water and
sewer connections in 1984, ground water use in
the area included private water supply wells for
homes and agriculture. Many of these wells
have been abandoned, and only a few currently
are in use. Since 1963, Spectra-Physics has
manufactured lasers and associated components
onsite, and has used VOCs including TCE as
part of the manufacturing processes.
Wastewater and rinse water were discharged
through five below-grade sumps into the
sanitary water system. Since 1962, Teledyne
Semiconductor, Inc., has operated a
semiconductor manufacturing facility onsite.
Below-grade sumps were used for acid
neutralization and waste TCE collection.
Furthermore, an underground storage tank (Tank
A) was used for storing waste solvents. In 1980,
all underground solvent handling activities were
discontinued and all chemicals are currently
stored above ground. From 1982 to 1984, State
investigations identified the release of VOCs
from solvent tanks into onsite soil at both areas.
Spectra-Physics and Teledyne have together and
separately implemented interim actions onsite.
In 1987, Spectra-Physics excavated and removed
all but one of the sumps and 6 feet of
contaminated soil from the facility area, and
installed a soil vapor extraction system as an
interim removal action to reduce VOCs in soil.
Teledyne excavated and removed Tank A and
the surrounding contaminated soil, and installed
ground water extraction systems on and around
the site to remove VOCs present in
concentrations above specified levels followed by
discharge of the extracted water to the sanitary
sewer system. This ROD addresses
contamination of the ground water aquifers and
onsite soil. The primary contaminants of
concern affecting the soil and ground water are
VOCs including PCE, TCE, and toluene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
expanding the existing soil vapor extraction
system at the Spectra-Physics area including
treatment of off-gases using granular activated
carbon; ground water pumping and treatment at
both the Teledyne and Spectra-Physics areas
using air stripping, followed by vapor phase
carbon to control air emissions, if the air levels
exceed permitted standards, followed by
discharging the treated water into an onsite
storm drain; continuing operation of the existing
ground water extraction systems at the offsite
Mountain View Area, with a contingency for
adding additional air stripping capacity prior to
discharge into the city sewer system; and soil
and ground water monitoring. The estimated
present worth cost for the Spectra-Physics area is
$2,729,595, which includes an annual O&M cost
of $188,600. The estimated present worth cost
for the Teledyne area is $2,000,000, which
includes an annual O&M cost of $86,000 for 30
years. The estimated present worth cost for
monitoring the offsite Mountain View Area is
$10,496,757, which includes an annual O&M cost
of $720,739 for 30 years. The estimated total
present work cost for this remedial action is
$18,226,352, which includes an annual O&M cost
of $909,425 for 30 years.

SYNERTEK (BUILDING #1), CA
June 28,1991
SITE HISTORY/DESCRIPTION:
The 1.5-acre Synertek (Building #1) site is a
former semiconductor products manufacturing
facility in Santa Clara, Santa Clara County,
California. The major site feature is a 24,000-
square-foot building (Building #1). The site is
composed of both onsite and offsite components.
The onsite component includes the area within
the Synertek property boundaries surrounding
Building #1, and the offsite component includes
the area contaminated by a ground water plume
that has migrated north past the property
boundaries and into the adjacent industrial park.
The surrounding area is zoned for light
industrial manufacturing. The site overlies three
shallow aquifer zones, and a deep aquifer zone
that provides up to 50% of the municipal
drinking water for the Santa Clara Valley
residences. It is suspected that hydraulic
separation among shallow aquifers is imperfect
owing to the discontinuous nature of sediment
types. Municipal water supply wells perforate
the aquifer zones nearby. Historical ground
water use in the area includes private
water-supply wells for homes and agriculture
prior to the construction of public water
connections and municipal water supply wells.
The location of one agricultural well still remains
unknown and is still under investigation. The
Synertek site manufactured semiconductor
products from 1978 to 1985. During this period
Synertek constructed and utilized two
underground tank systems to store chemicals
and solvents used in semiconductor
manufacturing processes, and an underground
concrete vault was constructed for process water
neutralization. In 1982, after Synertek submitted
a Facility Questionnaire to the State describing
their underground neutralization systems,
sumps, and tanks, the State initiated further site
studies to characterize subsurface pollution. The
State determined that accidental release of
chemicals leaking from the two underground
tank systems was a source of onsite ground
water and soil contamination. In 1985, the State
required the excavation and offsite removal of
the solvent and neutralization tanks. In addition,
onsite ground water pumping and treatment
using an air stripping tower began in 1987. A
well search for abandoned potentially
contaminated agricultural wells was conducted
in 1986 and one well is still unaccounted for.
This ROD addresses only contaminated ground
water since the contaminated soil and structures
were removed previously. The primary
contaminants of concern affecting the ground
water are VOCs including TCE, vinyl chloride,
1,1-DCE, cis-l,2-DCE, TCA, and 1,1-DCA.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continuing operation of the existing ground
water extraction and air stripping treatment
system; discharging the treated effluent to an
onsite storm drain; controlling air emissions by
carbon adsorption, if emissions exceed levels
currently permitted by the Bay Area Air Quality
Management District (BAAQMD); conducting a
pilot injection study to evaluate if the reinjection
of treated water would enhance the removal of
pollutants, speed ground water cleanup, and
reduce ground water discharge to the surface;
conducting potential conduit investigations to
locate and seal the remaining abandoned
agricultural well that is believed to exist close to
the plume; monitoring ground water; and
implementing institutional controls including
deed and well use restrictions. The estimated
present worth cost for this remedial action is
$895,000, which includes an annual O&M cost of
$61,000.

TRW MICROWAVE (ADVANCED MICRO DEVICES 901)
(SIGNETICS), CA
September 11,1991
SITE HISTORY/DESCRIPTION:
The 1-acre TRW Microwave site is an active
semiconductor manufacturing facility in
Sunnyvale, Santa Clara County, California. The
site is part of a larger study area that includes
four operable units (OUs): the 3-acre Advanced
Micro Devices (AMD) 901 site, the Signetics site,
the 1-acre TRW Microwave site, and a 100-acre
offsite contaminated ground water plume. Land
use in the area is predominantly commercial and
industrial. Residential property lies to the north
and west of the main facilities and overlies
portions of the offsite ground water OU. Six
aquifers are associated with the study area
including a deeper aquifer confirmed only at the
TRW and Signetics sites. Currently, the
contaminated ground water is not used as a
drinking water supply, but the State considers
several of the aquifers to be potential drinking
water sources. The 1-acre TRW portion of the
site has changed hands several times from 1968
to present; however, from 1974 to 1986, TRW
used its portion of the study area for
manufacturing semiconductors using solvents,
metals, and acids. These substances also were
used in semiconductor manufacturing at the
AMD and TRW sites from 1969 to the present
and from 1964 to the present, respectively. As a
result of responses to an information
questionnaire regarding an underground tanks
investigation at the TRW site, a number of
investigations were conducted that revealed
extensive contamination of onsite soil and
ground water. Leakage from the acid
neutralization system at the AMD and leakage
from an underground waste solvent storage tank
at the Signetics site resulted in a number of
investigations that also revealed extensive
contamination of onsite soil and ground water at
both of these sites. Several initial remedial
measures have been conducted at the TRW OU.
From 1983 to 1984, an underground waste
solvent storage tank and 120 cubic yards of
onsite contaminated soil were removed. From
1984 to present, ground water was pumped and
treated using air stripping, followed by onsite
discharge to surface water. Several initial
remedial measures also have been conducted at
the AMD OU. In 1983 and 1984, acid
neutralization sumps and about 217 cubic yards
of contaminated soil were removed. From 1984
to 1988, remediation of ground water was
implemented using extraction wells and
dewatering sumps. Several initial remedial
measures also were conducted at the Signetics
OU. From 1982 to present, ground water has
been pumped from various site locations and
treated using air stripping and carbon
adsorption, followed by air stripping to control
off-gases and reuse of the treated water in
industrial processes. Contaminated soil has been
removed from three separate locations, including
4,720 cubic yards of soil from a waste solvent
storage tank area in 1983. In 1989, three vapor
extraction wells were installed to treat
contaminated soil. In addition, two ground
water extraction systems pump contaminated
ground water from the 100-acre offsite plume.
The extracted water is treated at a neighboring
AMD facility using air stripping, followed by
liquid phase granular activated carbon polisher
and onsite discharge to surface water or reuse by
the facility. This ROD collectively addresses
final remediation of soil and ground water in the
four separate OUs within the study area. The
primary contaminants of concern affecting the
ground water are VOCs including PCE and TCE;
and other organics.

TELEDYNE SEMICONDUCTOR (SPECTRA-PHYSICS), CA
March 22,1991
SITE HISTORY/DESCRIPTION:
The Teledyne Semiconductor site is composed of
two Superfund sites: the Teledyne
Semiconductor site, a semiconductor
manufacturing facility, and the Spectra-Physics
site, a laser and related components
manufacturing facility, as well as offsite areas
associated with a contaminated ground water
plume in Mountain View, California. Land use
in the area is predominantly commercial and
industrial. The site is bordered by Permanente
Creek to the west and the City of Mountain
View landfill dewatering trench to the north.
Since the construction of public water and sewer
connections in 1984, most private wells have
been abandoned; however, eight private wells
are currently operational for residential and
agricultural uses. Since 1962, Teledyne
Semiconductor, Inc., has operated a semi-
conductor manufacturing facility onsite. From
1962 to 1980, the facility used two 1,400-gallon
underground sumps for acid neutralization and
waste TCE collection, and a 2,000-gallon waste
solvent tank (Tank A) for collection and disposal
of liquid chemical wastes onsite. In 1980, all
underground solvent handling activities were
discontinued and waste holding and disposal
facilities were moved above ground.
Spectra-Physics, Inc., has manufactured lasers
and associated components onsite since 1963,
and has used VOCs including TCE as part of the
manufacturing processes. Wastewater and rinse
water were discharged through five below-grade
sumps into the sanitary water system. From
1982 to 1984, State investigations identified the
release of VOCs from solvent tanks into onsite
soil at both areas. Teledyne and Spectra-Physics
have together and separately implemented
interim actions onsite. Teledyne excavated and
removed Tank A and the surrounding
contaminated soil, and in 1986, installed ground
water extraction systems on and around the site
to remove VOCs present in concentrations above
specified levels and discharge extracted water to
the sanitary sewer system. In 1987,
Spectra-Physics excavated and removed all but
one of the sumps and six feet of contaminated
soil from the facility area, and installed a soil
vapor extraction system as an interim removal
action to reduce VOCs in soil. This ROD
addresses contamination of the ground water
aquifers and onsite soil. The primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE, TCE,
toluene, and xylenes.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
expanding the existing soil vapor extraction
system at the Spectra-Physics area including
treatment of off-gases using granular activated
carbon to control air emissions; ground water
pumping and treatment at both the Teledyne
and Spectra-Physics areas using air stripping,
followed by vapor phase carbon to control air
emissions, followed by discharging the treated
water into an onsite storm drain; continuing
operation of the existing ground water extraction
systems at the offsite Mountain View Area, with
a contingency for adding additional extraction
wells and treating the extracted water using air
stripping prior to discharge into the city POTW;
and conducting soil and ground water
monitoring. The estimated present worth cost
for this remedial action at only the Teledyne area
is $2,000,000, which includes an annual O&M
cost of $86,000 for 30 years. The estimated
present worth cost for the Spectra-Physics area is
$2,729,595, which includes an annual O&M cost
of $188,600. The estimated present worth cost
for monitoring the offsite Mountain View Area
is $10,496,757, which includes an annual O&M
cost of $720,739 for 30 years. The estimated total
present cost for this remedial action is
$18,226,352, which includes an annual O&M cost
of $909,425 for 30 years.

VALLEY WOOD PRESERVING, CA
September 27,1991
SITE HISTORY/DESCRIPTION:
The 14.4-acre Valley Wood Preserving (VWP)
site is a former wood preserving facility in
Turlock, Stanilaus County, California. Land use
in the area is predominantly agricultural, and
one residence is located onsite. There are
subsurface irrigation drains at the site, which
eventually discharge to the San Joaquin River
about 12 miles west of the site. From 1973 to
1979, VWP used a solution of chromated-copper
arsenate (CCA) to preserve lumber onsite. Wood
preserving chemicals were mixed and stored
onsite in three above-ground storage tanks.
After treatment, the wood was allowed to drip
dry on paved and unpaved areas. Chemical
spills, leaking tanks, improper onsite disposal
practices, and chemical drippings from the
treated lumber are known sources of
contamination. In 1979, State investigations
identified metals including arsenic and
chromium in an onsite storage pond, holding
tanks, onsite and offsite soil, and the onsite
underlying shallow aquifer. In 1989, EPA
investigations identified low levels of chromium
contamination in several domestic wells, and
required VWP to install an interim ground water
extraction and electrochemical treatment system
to help contain the migration of contamination.
EPA also required VWP to design a plan for the
development of an alternative water supply for
any affected residences. VWP also installed
three deep ground water wells to serve as
domestic water supplies. This ROD provides a
final remedy for contaminated soil and ground
water. The primary contaminants of concern
affecting the soil and ground water are metals
including arsenic and chromium.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating approximately 15,000 cubic yards of
contaminated surface and subsurface soil;
treating the soil using cement-based fixation;
backfilling excavated areas with treated soil that
meets State criteria, maintaining stabilized soil
mass onsite to prevent future exposure; placing
treated soil that exceeds State criteria in lined
cells onsite; collecting, handling, and disposing
of leachate; pumping and treatment of
contaminated ground water using
electrochemical treatment to reduce hexavalent
chromium to its trivalent form, followed by
treating the residual using alumina adsorption to
remove any residual arsenic; disposing of
ground water onsite by infiltration and
evaporation at one or more percolation ponds, or
by underground injection through subsurface
injection wells; disposing of sludge generated
during the treatment process offsite; conducting
soil, ground water, surface water, and air
monitoring; and implementing institutional
controls possibly including deed restrictions,
The estimated present worth cost for this
remedial action is $3,850,000, which includes an
annual O&M cost of $224,000.
PERFORMANCE STANDARDS OR GOALS:
Soil excavation clean-up standards are based on
an excess cancer risk level of 10~6 for surface soil
and levels protective of ground water from
contaminated leachate for subsurface soil.
Ground water clean-up standards are based on
State levels and potential health risks.
Chemical-specific soil goals include arsenic
2 mg/kg (risk-based) and hexavalent chromium
4 mg/kg (risk-based) for surface soil; and arsenic
5 ug/kg and hexavalent chromium 5 ug/kg for
subsurface soil. State criteria require a liner
below soil containing arsenic and chromium
concentrations greater than 500 mg/kg and
below soil exhibiting leachable arsenic and
chromium at 5 ug/1. Ground water clean-up
goals include arsenic 16 ug/1 (health-based) and
chromium 50 ug/I (State).

VAN WATERS & ROGERS, CA
September 11,1991
SITE HISTORY/DESCRIPTION:
The 13.7-acre Van Waters & Rogers site is a
commercial chemical storage, handling, and
distribution facility in San Jose, California. Land
use in the area is predominantly commercial and
industrial. Nearby surface drainage features
include Coyote Creek, approximately 1,200 feet
to the east, and the Guadalupe River,
approximately 6,000 feet to the west, that
discharge to San Francisco Bay 9 miles to the
north. Since 1976, Van Waters & Rogers has
used the site for bulk chemical transfers; storage
in drums and underground tanks; chemical
blending, packaging, and distribution; and
rinsing of containers. Surface features from
which releases of organic chemicals have
occurred are above-ground storage tanks,
rail-mounted tank cars, drum fillers,
underground storage tank (UST) fill pipe
manifolds, and a hazardous waste storage area.
Subsurface features include 37 USTs; subsurface
product transfer piping; and the subsurface
storm drain system, which eventually discharges
to the Guadalupe River. Fourteen USTs are not
in service and are currently empty. With the
exception of one tank used to store diesel fuel,
all USTs have been used to store various
industrial chemicals including PCE, toluene, and
xylenes. During a survey of regional hazardous
waste facilities in 1982, the State identified
VOCs, selected aliphatic hydrocarbons, aromatic
hydrocarbons, ketones, glycols, and alcohols in
onsite soil and ground water. Potential sources
of contamination include a 1977 accidental
release of PCE from an above-ground
12,000-gallon tank at the loading dock and
various leaks from USTs and associated piping.
Van Waters & Rogers began an interim ground
water remediation program in 1986 that involves
ground water extraction and treatment using air
stripping with onsite discharge to the storm
drain. This ROD provides a final remedy for
onsite contaminated soil, debris, and ground
water. The primary contaminants of concern
affecting the soil, debris, and ground water are
VOCs including PCE and TCE.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
treating approximately 8,100 cubic yards of soil
"hot spots" containing more than 10 mg/kg of
one or more of PCE, TCA, and TCE using in-situ
vapor extraction; temporarily capping 46,000
cubic yards of soil containing greater than
1 mg/kg total VOCs, including areas containing
USTs until tank removal can take place;
removing USTs at a later date and investigating
adjacent soil; expanding the existing upper
aquifer ground water pumping and treatment
system by adding an air stripping unit and
converting existing monitoring wells to
extraction wells, wherever possible; treating the
off-gases from the new air stripping unit;
treating the lower aquifer by either granular
activated carbon or air stripping; discharging the
treated ground water onsite to the storm drain
system; monitoring soil and ground water; and
implementing institutional controls including
deed restrictions. The estimated present worth
cost for this remedial action is $4,997,000, which
includes a net present value O&M cost of
$4,374,000.
PERFORMANCE STANDARDS OR GOALS:
Clean-up goals for soil are intended to minimize
contaminant migration to ground water.
Chemical-specific initial soil goals for PCE and
TCE are 10 mg/kg. Final soil goals will be
1 mg/kg for total VOCs. Chemical-specific

AMERICAN LAKE GARDENS (McCHORD AFB-AREA D), WA
September 19,1991
SITE HISTORY/DESCRIPTION:
The American Lake Gardens (McChord
AFB-Area D) site is an active U.S. Air Force Base
located at McChord Air Force Base, Pierce
County, Washington. The site consists of two
areas, Area D and American Lake Garden Tract
(ALGT). Area D is located entirely on-base.
Area D activities include Air Force Base
administration, flight operations support
functions, and housing and recreation facilities.
Approximately 2,384 people reside in the Area D
housing facilities. ALGT is an off-base
commercial and residential area with
approximately 3,431 residents and various
businesses. Hydrogeologic units exist onsite
including a series of confined and unconfined
aquifers that appear to be hydraulically
connected. Various surface water bodies exist
near the site and are principally ground
water-fed. From the mid-1940's to the present,
no known industrial activities have occurred in
the ALGT area; however, seven waste disposal
sites have operated within the Area D portion of
the site. In 1981, the Air Force initiated a
multi-phase program to identify past disposal
sites and contaminants and to eliminate public
health risks. Concurrent with DOD
investigations, EPA discovered TCE in ground
water monitoring wells installed at the ALGT,
and in 1984, concluded that waste disposal sites
in Area D were the likely source of ground
water contamination. Modeling studies indicate
that most of the soil contamination by VOCs has
moved into the ground water, and that DNAPLs
may continue to act as a secondary source of
ground water contamination. In 1986, the Air
Force provided an alternate water source to
residents of ALGT, and subsequently connected
80% of the residences to a public water supply.
This ROD addresses remediation of the
contaminated onsite and offsite ground water
plume, as a final remedy. The primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCE,
toluene, and xylenes; other organics; and metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and treating both the onsite and offsite
ground water contaminant plumes in the
confined aquifer using an onsite multi-bed
carbon adsorption treatment facility, followed by
recharging or irrigating the treated ground water
onsite; regenerating the spent carbon offsite;
monitoring the ground water contaminant
plume; and implementing institutional controls
such as deed, ground water, and land use
restrictions. The estimated present worth cost
for this remedial action ranges from $4,445,000 to
$6,949,000, for interest rates of 10% and 4%
respectively, which includes an annual O&M
cost of $341,000 for years 0-2 and $318,000 for
years 3-30.
PERFORMANCE STANDARDS OR GOALS:
Ground water will be restored to levels
consistent with State and Federal MCLs.
Chemical-specific goals for ground water include
cis-l,2-DCE 70 ug/1 (MCL), 1,1-DCE 0.7 ug/1
(Model Toxic Control Act), TCE 5 mg/1 (MCL),
and vinyl chloride 0.04 ug/1 (Model Toxic

surrounding communities. Demilitarizing
(demil) operations were conducted from 1940
until 1978, and included collecting condensate
and solid explosive within a holding tank,
followed by removal of the solid material from
the wastewater before final discharge. Site F, a
wastewater lagoon, was used between 1960 and
1971 to dispose of final wastewater solution.
Periodically, the lagoon was allowed to drain.
Waste materials present in surficial sediment of
the lagoon were burned off in place with waste
oils, or transported to the onsite ordnance
burning area for thermal destruction. Between
1972 and 1980, wastewater was collected into
55-gallon barrels and delivered to the SUBASE
liquid-waste incinerator. Several onsite
investigations of the distribution and transport of
waste constituents at Site F have occurred since
1971. Based on data collected, it was confirmed
that soil in the lagoon area is contaminated by
ordnance constituents. In 1972,500 cubic feet of
soil was excavated from the top several feet of
the lagoon and transported to the onsite
ordnance burning area for burning. In 1980, the
lagoon was filled in and covered with a low
permeability asphalt cover Ground water
quality data collected at Site F during prior
studies indicated that only the Shallow Aquifer
has been impacted by Site F. This ROD is an
interim remedial action addressing ground water
contamination at Site F as operable unit 2 (OU2).
The intent of this remedy is to contain the
contaminated ground water plume. A future
ROD will address final remediation of both soil
and ground water. The primary contaminants of
concern affecting the ground water are organics
including RDX; 2,4,6-TNT; 2,4-DNT; 2,6-DNT;
1,3,5-TNB; 1,3-DNB; N-nitrate; and nitrobenzene.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
pumping and treatment of ground water from
the Shallow Aquifer using UV-oxidation;
reinjecting the treated ground water onsite into
the Shallow Aquifer, or infiltrating it onsite
using a recharge basin; monitoring ground
water; and providing design information, as
applicable, for the final remedy. If the
UV-oxidation process cannot achieve the
specified performance standards due to either
technological or economic concerns, then carbon
adsorption will be coupled with the
UV-oxidation system to complete the treatment
process prior to disposal. The estimated present
worth cost for this remedial action is $2,515,000,
which includes an O&M cost of $1,300,000 over
2 years.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific ground water clean-up goals
are based on Model Toxic Control Act (MTCA)
clean-up standards and include RDX 5 ug/1;
2,4,6-TNT 3 ug/1; 2,4-DNT 0.1 ug/1; 2,6-DNT
0.1 ug/1; 1,3,5-TNB 0.8 ug/1; 1,3-DNB 2 ug/1;
N-nitrate 10,000 ug/1; and nitrobenzene 8 ug/1.

BUNKER HILL MINING AND METALLURGICAL COMPLEX, ID
August 30,1991
SITE HISTORY/DESCRIPTION.
The Bunker Hill Mining and Metallurgical
Complex site is a 21-square-mile area centered
around an inactive industrial mining and
smelting site, and includes the Cities of Kellogg,
Smelterville, Wardner, Pinehurst, and Page, in
Shoshone County, Idaho. The inactive industrial
complex includes the Bunker Hill mine and mill,
a lead smelter, a zinc smelter, and a phosphoric
acid fertilizer plant, all totaling several hundred
acres. Furthermore, the site includes the South
Fork of the Coeur d'Alene River, an alluvial
floodplain bordered by mountains, numerous
valleys and gulches, and vegetated residential
areas. In 1886, the first mill for processing lead
and silver ore was constructed at the site.
Operations were expanded in later years with
the addition of a lead smelter; a blast furnace;
and electrolytic zinc, sulfuric acid, phosphoric
acid, and fertilizer plants. Onsite operational
and disposal practices have caused the
deposition of hazardous substances (e.g., metals)
throughout the valley via airborne particulate
deposition, alluvial deposition of tailings
dumped in the river, and migration from onsite
sources. Initially, most of the solid and liquid
residue from the complex was discharged into
the river. When the river flooded, these
materials were deposited onto the valley floor,
and have leached into onsite soil and ground
water. Although some of the industrial wastes
have been removed and disposed of offsite,
thousands of tons of sludge, tailings, flue dust,
and other wastes still remain onsite.
Contamination at the site is a result of tailings
deposition in the floodplain, and airborne
deposition from smelter and mill complex
emissions. A fire in 1973 severely reduced air
pollution control capacity at the lead smelter. A
1974 public health study and concurrent
epidemiologic and environmental investigations
concluded that atmospheric emissions of
particulate lead from the active smelter were the
primary sources of elevated blood lead levels in
local children. In 1977, two tall stacks were
added to disperse contaminants from the
complex. The complex ceased smelter operations
in 1981, but continued limited mining and
milling operations from 1988 to early 1991. In
1989, EPA began a removal program to excavate
lead-contaminated soil from affected residential
properties. Federal and State agencies have
designated a 21-square-mile study area, which
has been divided into populated areas and
non-populated areas for remediation. This ROD
addresses contaminated residential soil within
the populated areas of the site, and includes four
incorporated communities and three
unincorporated residential areas as operable unit
1. The nonpopulated areas of the site as well as
all other contaminated media in the populated
areas (e.g., house dust, and commercial
properties) will be addressed in a future ROD.
The primary contaminants of concern affecting
residential area soil are metals including arsenic
and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
soil sampling; excavating contaminated soil and
sod exceeding 1,000 mg/kg lead on
approximately 1,800 residential properties, and
replacing it with clean soil and sod; disposing of
the contaminated soil and sod at an onsite
repository; capping the repository; placing a
visual marker if lead levels in soil exceed
1,000 mg/kg below the depth of excavation;
revegetating the area; conducting long-term
environmental monitoring; and implementing
institutional controls including deed and land
use restrictions. The estimated present worth
cost for this remedial action is $40,600,000, which
includes an annual O&M cost of $460,000 for 30
years.

NORTHWEST TRANSFORMER - MISSION POLE (AMENDMENT), WA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 1.6-acre Northwest Transformer - Mission
Pole site, a former transformer storage and
salvage facility, is 2 miles south of Everson in
Whatcom County, Washington. The site is
bordered by low-density residential areas to the
north and east, and farmland to the south.
Storage and salvage operations were conducted
in an onsite barn where PCB-contaminated
dielectric fluid was drained from the
transformers prior to dismantling. Transformer
casings and associated parts were incinerated
onsite, and some of the recovered oil was burned
to heat the barn. Spills and leakages of
PCB-laden oil onto the ground occurred
frequently. Additionally, oil was dumped
directly into a seepage pit onsite, and has
contaminated soil and possibly ground water.
EPA studies from 1977 to 1985 identified PCS
concentrations as high as 38,000 mg/kg in onsite
media. In 1985, EPA removed 1,400 cubic yards
of PCB-contaminated soil and debris, 6,660
gallons of PCB-contaminated liquids, and several
contaminated transformer casings. In addition,
EPA initiated a ground water monitoring
program and imposed site access restrictions. In
1987, sufficient PCB contamination was identified
in the soil to warrant further site remediation. A
1989 ROD addressed remediation through
excavation, consolidation, and onsite treatment
using in-situ vitrification. This ROD amends the
1989 ROD and provides a change in the remedy
for soil due to excessive cost. The primary
contaminant of concern affecting the soil is PCB,
an organic.
SELECTED REMEDIAL ACTION:
The amended remedial action for this ROD
includes incinerating approximately 70 cubic
yards of soil contaminated with PCBs at levels
greater than or equal to 50 mg/kg at a TSCA-
approved facility, landfilling approximately 1,500
cubic yards of soil contaminated with PCBs at
levels greater than or equal to 1 mg/kg and less
than 50 mg/kg off site at a TSCA-approved
facility; demolishing the barn and disposing of
the debris off site; testing the soil and concrete
within the barn; placing a soil cover over the
entire site; and implementing institutional
controls, if necessary. The estimated capital cost
for this amended remedial action ranges from
$1,400,000 to $4,000,000 depending on the
amount of soil removed. O&M costs were not
provided.
PERFORMANCE STANDARDS OR GOALS:
Chemical-specific soil clean-up goals are based
on the Washington State Model Control Act and
include PCBs 1 mg/kg.
INSTITUTIONAL CONTROLS:
If complete removal of soil with PCB levels
>1 mg/kg cannot be demonstrated and
hazardous materials remain onsite, institutional
controls will be implemented.

UNION PACIFIC RAILROAD YARD, ID
September 10,1991
SITE HISTORY/DESCRIPTION:
The Union Pacific Railroad Yard site is an active
railyard located in Pocatello, Bannock County,
Idaho. Land use in the area is mixed
commercial and light industrial, with some
residential areas. Site features include sludge
pits along the northwestern edge of the site, and
Portneuf River, which is located 1,000 feet from
the pit. Ground water in the vicinity of the
sludge pit occurs in two distinct water-bearing
deposits, the Upper and Lower Aquifers, which
appear to be hydraulically connected. Union
Pacific Railroad (UPRR) began operations around
the turn of the 20th century. Site operations
have included maintenance and repair work,
train assembly, and refueling, which involved
the use of various fuels, cleaning agents,
detergents, and degreasers, including
halogenated and non-halogenated hydrocarbon-
based solvents. UPRR constructed a treatment
plant in 1961 to receive industrial wastewater
and surface stormwater run-off from the
railyard. Until 1983, sludge from the treatment
plant's oil/water separator and from a dissolved
air flotation unit was disposed in the onsite
sludge pit. Currently, the sludge pit contains
approximately 2,500 cubic yards of sludge and
1,700 cubic yards of contaminated soil beneath
the sludge. In 1983, EPA determined that
seepage from UPRR's sludge pit, and from a
nearby area where an oil tie treating facility was
located were contributing to Upper Aquifer
ground water contamination. In 1985, UPRR, the
only identified PRP, conducted an investigation
of the railroad yard, and the sludge pit was
determined to be the principal source of onsite
contamination. This ROD addresses
contamination of the Pocatello Sludge Pit located
at the UPRR property. The primary
contaminants of concern affecting the soil,
sediment, sludge, and ground water are VOCs,
other organics including PAHs and
petroleum-based hydrocarbons (oils), and metals.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
implementing a comprehensive soil, sediment,
sludge, and ground water sampling effort prior
to remedial activities to determine background
levels and to set final remediation goals;
excavating to the maximum extent practicable up
to 4,200 cubic yards of visibly-contaminated soil,
sediment, and sludge; testing these media for
compliance with land disposal restriction
treatment standards, followed by disposal at an
approved offsite landfill; treating soil remaining
beneath the excavated area using in-situ soil
flushing as part of the Upper Aquifer ground
water treatment system, backfilling, grading, and
capping the entire pit boundary; extracting and
treating nonaqucous phase liquid contaminants
from the Upper Aquifer ground water using an
onsite oil/water separator and a dissolved air
flotation unit; discharging effluent offsite to a
POTW; placing skimmed oil in an onsite holding
tank for sale to a recycler; disposing of residual
sludge from ground water treatment offsite;
conducting quarterly sampling and analysis of
ground water to ensure remediation goals are
met; constructing a fence around the sludge pit;
providing advanced funding for design and
installation of an alternate water supply system
to be implemented if monitoring indicates that
ground water contamination has not beeri
adequately remediated; monitoring ground
water, surface water, and air; and implementing
administrative and institutional controls
including deed, land, and ground water use
restrictions. The estimated present worth cost
for this remedial action is $3,797,550, which
includes a present worth O&M cost of $1,657,900
for 30 years.

YAKIMA PLATING, WA
September 30,1991
SITE HISTORY/DESCRIPTION:
The 0.94-acre Yakima Plating site is an inactive
nickel-chrome automobile bumper replating
facility in Yakima, Yakima County, Washington.
The site lies within a mixed light commercial
and residential area, and there are four schools
within 1 mile of the site. Ground water from the
shallow alluvium aquifer supplies much of the
domestic and irrigation water in the Yakima
Basin, and many residences adjacent to the site
utilize private ground water wells for their water
supply. Yakima Plating began operations in
1965 utilizing 20 to 30 above-ground holding
tanks, which were stored within the plating
building. These tanks were used during the
electroplating operation cleaning, plating, and
rinsing processes. Rinse water and spent plating
tank solutions were disposed of in a floor drain
within the plating room. The floor drain was
connected to an underground sedimentation tank
and drain field line that collected the
sedimentation tank overflow and distributed the
wastewater to subsurface soil. The wastewater
system operated from 1965 until plating
operations ceased in 1990. Site assessments and
investigations conducted by EPA contractors in
1984 and 1990 determined that the sludge and
effluent from the settling tank were a dangerous
waste under State regulations and that the
potential exists for public exposure to metals
from contact with contaminated surface and
subsurface soil. This ROD addresses
remediation of contaminated onsite soil, debris,
and sludge. The primary contaminants of
concern affecting the soil, debris, and sludge are
organics including pesticides; and metals
including arsenic, chromium, copper, lead, and
nickel.
SELECTED REMEDIAL ACTION.
The selected remedial action for this site includes
removing 1,500 gallons of liquid and 6.5 cubic
yards of sludge currently in tanks and
containers, and treating and disposing of these
materials at an offsite facility; excavating,
treating, and disposing of contaminated soil at
an offsite landfill; excavating and
decontaminating underground tanks using a
solvent or water-based solution; abandoning the
tanks in place, and covering the tank areas with
clean fill; treating and disposing of any liquids
or sludge generated during the decontamination
process at an offsite facility; and excavating and
disposing of 540 cubic yards of soil and
underground drain lines at an offsite facility;
ground water monitoring; and implementing
institutional controls including land and ground
water use restrictions. The estimated present
worth cost for this remedial action ranges from
$310,000 to $377,000, depending on the type of
solution used for debris decontamination. There
are no O&M costs associated with this remedial
action.
PERFORMANCE STANDARDS OR GOALS:
Clean-up levels for soil and ground water are set
at the more stringent of Federal and State
standards. Chemical-specific soil remediation
goals include arsenic 20 mg/kg, chromium
400 mg/kg, lead 50 mg/kg, and DDT 2.9 mg/kg.
INSTITUTIONAL CONTROLS:
Land use and ground water restrictions will be
implemented at the site.

An enhanced recovery process will
be applied to the free coal tar (i.e.,
coal tar at 100% pore volume
saturation) areas, and will remove
and treat 60-70% of the free coal

Federal standards, further
remediation was deemed necessary
to prevent additional leaching of
contaminants from the soil to the

clean-up goals
Soil action levels for saturated and
unsaturated soil and "principal
threat" action levels were
developed based on MCLs, RCRA
toxicity characteristic levels
(TCLP), and health-based criteria.
The target clean-up goal for
surface soil is arsenic 21 mg/kg.
Action levels for unsaturated soil
include benzene 0.009 mg/kg,
PCE 0.051 mg/kg, TCE 0.017
mg/kg, and arsenic 450 mg/kg.
Action levels for saturated soil
include benzene 0.002 mg/kg,
PCE 0.012 mg/kg, TCE
0.004 mg/kg, and arsenic
210 ug/kg based on protection of
GW. Principal threat action levels
include benzene 10 mg/kg, PCE
14 mg/kg, TCE 10 mg/kg, and
arsenic 1,000 mg/kg. GW clean-
up goals are based on Federal
MCLs, proposed MCLs, a 10"*
excess cancer risk level, and an
HI=1. Chemical-specific GW
clean-up goals include benzene
0.005 mg/1 (MCL), PCE 0.005
mg/1 (pMCL), TCE 0.005 mg/1
(MCL), and arsenic 0.05 mg/1. A
State ARAR to remediate GW to
background levels will be waived
because of technical
impracticability.

SECTION V
DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
SOURCE CONTROL AND GROUND WATER
Source Technologies:
Treatment technology for source material are grouped based on the primary functions for which
they are generally used: destruction/detoxification, separation/recovery, immobilization, and
other. The specific technologies listed are those identified in the RODs.
I. DESTRUCTION/DETOXIFICATION
A. Bioremediation
Biological treatments use microorganisms to degrade primarily low to moderate levels of
organic contaminants in aqueous waste streams and soil. Biological treatments include:
In-Situ Bioremediation - uses natural populations or seeded bacteria to
biodegradc organic compounds. The biological process may be
accelerated by introducing nutrients and oxygen. This process is often
used in conjunction with a ground water pumping and reinjection
system to circulate nutrients and oxygen through a contaminated aquifer
and associated contaminated soil.
Solid/Slurry Phase Bioremediation - involves commingling excavated
organic-contaminated soil and sludge with bioactive microorganisms in a
mobile batch reactor or an in-ground reactor. Waste is mixed with water
to create a slurry composition, and the slurry is mixed to maximize
treatment of organic contaminants. Upon completion of the process, the
slurry is dewatered and the treated soil is disposed of.
B. Chemical Destruction/Detoxification
Chemical destruction/detoxification processes alter the hazardous substances to produce
a by-product residue that is less hazardous than the original waste and may be easier to
remove from the waste stream. Chemical destruction/detoxification processes include:
Chemical Reduction/Oxidation (redox) - a destructive process that
changes the chemical nature of the nature of the contaminants.
Dechlorination - is a destruction process in which chlorine is chemically
removed from chlorinated organic compounds. This process converts
the more toxic compounds into less toxic, more water soluble products.
The transformation of contaminants within the soil produces compounds
that are more readily removed from the soil.
639

SOURCE CONTROL AND GROUND WATER
(CONTINUED)
C Thermal Treatment
Thermal treatments use heat to destroy or detoxify hazardous substances, encompassing
such technologies as incineration, pyrolysis, and wet air oxidation. Specific incineration
types include rotary kiln, liquid injection, fluidized-bed, and infrared treatment.
Incineration - is a controlled flame combustion process in which organics are
destroyed producing carbon dioxide, water, and other compounds.
Pyrolysis - is a decomposition process in which organics are thermally
decomposed into their individual elements, in an oxygen deficient atmosphere.
Wet Air Oxidation - is a process that involves adding high pressure and
temperature to a water solution or suspension to destroy organics.
II. SEPARATION/RECOVERY
A. Chemical/Physical Extraction
Chemical/Physical Extraction is a transfer/separation process in which contaminants are
dissociated from the matrix either through a chemical or a physical process and are
dissolved in a liquid or gaseous phase which may require further treatment.
Chemical/physical extraction processes include:
In-SituSoil Flushing - is an in-situ extraction process that uses a flushing
agent, e.g., water to extract contaminants.
In-Situ Vacuum/Soil Vapor Extraction - is an in-situ process that
involves extraction of VOCs from soil using a vacuum or forced air. This
process is generally used with other technologies since it transfers
contaminants from the soil to air and water waste streams.
Soil Washing - is a physical/chemical separation technology in which
excavated soil is washed with fluids to remove contaminants. Soil
washing is generally followed by other technologies in a treatment train.
640

DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
SOURCE CONTROL AND GROUND WATER
(CONTINUED)
B. Thermal Desorption
Thermal Desorption uses heat to extract volatile organics from the matrix and may be
followed by other treatments to collect and/or destroy contaminants. Thermal
desorption processes include:
Ex-Situ Thermal Desorption - is a physical transfer process that uses air, heat, and
mechanical agitation to change volatile organic compounds (VOCs) in soil into a
gas stream, where the contaminants are then further treated.
In-situ Stream Stripping/Hot Air Stripping - involves the injection of steam or
hot air into soil to volatilize VOCs. As VOCs rise to the surface they are
condensed or trapped on activated carbon.
III. IMMOBILIZATION
Immobilization
The term "immobilization" is used to mean any of the technologies which limit the
solubility or mobility of contaminants. The term "fixation" has also been used as a
synonym for immobilization. Technology types which fall within the realm of
immobilization include:
Stabilization - involves the addition and mixing of materials that limit the
solubility or mobility of the waste constituents even though the physical
characteristics of the waste may not be changed.
Solidification/Stabilization - involves the addition and mixing of
materials that limit the solubility or mobility of the waste constituents,
and results in a monolithic structure.
Sorbent Solidification - involves the addition and mixing of materials that
limit the mobility of the waste constituents through the action of
sorption,
IV. OTHER
In-situ Vitrification (ISV) - is a thermochemical treatment process that destroys,
removes, or immobilizes hazardous wastes by electrically melting the waste media (e.g.,
soil) which upon cooling creates an extremely stable glass-like solid. ISV can be used to
treat soil and sludge contaminated with radioactive, inorganic, or organic wastes or
mixtures of these contaminants.

DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
SOURCE CONTROL AND GROUND WATER
(CONTINUED)
Ground Water Technologies:
Treatment technologies for ground water are grouped based on the categories commonly used in
the waste water treatment industry: chemical/physical treatment biological, and other. The
technologies are listed in their order of appearance in Exhibit 5.
I. CHEMICAL/PHYSICAL
Air Stripping (Desorption) - is a physical process that involves bringing
ground water into close contact with air thereby causing VOCs in the
liquid phase to transfer to the gas phase. For ground water, this
generally is accomplished by injecting water into an air stream. Exhaust
air may have to be treated (e.g., using carbon adsorption) to remove
VOCs before discharge to the atmosphere.
Carbon Adsorption - is a physicochemical process that involves using
activated carbon as a sorbent to remove primarily soluble organics from
air and water. As contaminated ground water contacts activated carbon,
organic molecules become physically/chemically attached (i.e.,
adsorbed) to the carbon surface. There are two basic types of activated
carbon: granular and powdered, based on the size of the carbon
particles.
Precipitation - is a physicochemical process that involves transforming a
contaminant from solution into a solid phase. Precipitation for ground
water remediation is used primarily for the removal of heavy metals
using such precipitating chemicals as lime, alum, or iron salts. Chemical
precipitation is followed frequently by flocculation to enhance settling of
solid particles for subsequent removal by filtration or sedimentation.
Physical precipitation, including cooling, heating or altering the solvent
concentration, also can be used to alter solubilities and precipitate
contaminants.
Granular Activated Carbon - is carbon prepared by heating various types
of woods and coal to drive off hydrocarbons but with insufficient air to
sustain combustion. The resulting char is activated by exposure to an
oxidizing gas at high temperatures. The carbon particles generally are
used in carbon adsorption processes (see above).
Filtration - is a physical process that involves forcing contaminated
ground water through a porous granular-media filter (e.g., sand,
anthracite) to remove suspended particles. Several mechanisms are
involved in filtering suspended particles from the ground water,
including straining, flocculation, and sedimentation.
642

DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
SOURCE CONTROL AND GROUND WATER
(CONTINUED)
Ion Exchange - is a reversible process whereby toxic ions (i.e., anions and
cations) in solution are exchanged with less harmful, similarly charged
ions electrostatically attached to a solid synthetic resin material. The
toxic ions having a stronger affinity to the resin, will replace the original
ions that were placed on the resin before treatment. Once the available
exchange sites on the resin are filled, the resin can be regenerated.
Sedimentation - is the removal of suspended solids from wastewaters by
the gravitational settling of particles heavier than water. Sedimentation
may be used in ground water treatment after biological treatment or
precipitation/flocculation to remove biomass or precipitants.
UV Peroxidation - is a chemical oxidation process that uses hydrogen
peroxide in the presence of a catalyst to generate hydroxyl radicals that
react with organics and reduced compounds to yield carbon dioxide,
water, salts, simple organic acids, and/or sulfates thereby reducing the
toxicity and organic content of wastewaters. The application of
ultraviolet (UV) light to the waste treatment (photolysis) to
enhance/induce chemical
transformations can be used in conjunction with peroxidation. A major
advantage of UV application is that specific bonds can be targeted by
selecting the appropriate frequency of the light source.
Chemical Treatment - involves chemical reduction-oxidation (redox)
reactions in which the oxidation state of at least one reactant is raised
while that of another is lowered. Redox reactions can detoxify and
enhance biodegradability or adsorption (oxidation), or reduce solubility
(reduction).
Flocculation - is a chemical/physical process that involves agitating
chemically treated water to enhance precipitation and induce
coagulation. Fine suspended particles formed during precipitation
collide during gentle mixing, and agglomerate into larger heavier
particles or floes and settle out. Flocculating agents such as alum, lime,
iron salts, and organic flocculating agents are added to reduce natural
repelling surface charges on particles, and physical agitation is used for
the formation of large floes.
Activated Alumina - is an adsorption process that is used to remove
dissolved inorganic constituents such as arsenic, fluoride, and selenium.
As contaminated ground water contacts activated alumina, inorganics
become physically/chemically attached (i.e., adsorbed) to the alumina
surface. Activated alumina is a highly porous, granular form of
aluminum oxide.
643

DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
SOURCE CONTROL AND GROUND WATER
(CONTINUED)
Aeration - is a gas-liquid mass-transfer process that is used for adding
oxygen during biological treatment processes, or for air stripping VOCs
from wastewaters.
Neutralization (pH Adjustment) - is a chemical process that involves
adding an acid (e.g., sulfuric acid) or base (e.g., lime) to adjust the pH.
Neutralization may be used as a pretreatment before biological or
chemical treatment.
Reverse Osmosis - is a physical separation process involving membrane
filtration. Sufficient pressure is applied to a concentrated solution to
force the water from the solution to flow through a semi-permeable
membrane but selectively prevents impurities from passing through the
membrane; concentrations of impurities build up on the pressure
induced side of the membrane. Reverse osmosis is generally limited to
polishing low flow streams containing highly toxic contaminants, and is
especially effective for high molecular weight organics and ions.
II. BIOLOGICAL
Biological Treatment (In-Situ Bioremediation) - is an in-situ process that
uses natural populations or seeded bacteria in an aquifer to transform
organic contaminants (e.g., petroleum hydrocarbons) into less hazardous
compounds thereby reducing the concentration of hazardous substances.
The biological process generally involves the aerobic oxidation of organic
compounds by bacteria, which produce water, carbon dioxide, and new
biomass as products. In-situ biological treatment generally is
accomplished via a ground water pump-and-reinjection system and is
often limited by the ability to provide additional oxygen and nutrients to
the bacteria.
Ex-situ Bioremediation - is a batch process that uses bacteria to degrade
organic matter aerobically or anaerobically. Aerobic bioremediation
involves the conversion of organics to carbon dioxide, water, and new
bacteria cells. Anaerobic bioremediation generally involves the
conversion of organics to carbon dioxide and methane gas in the absence
of molecular oxygen. There are several biological treatment processes,
including conventional activated sludge systems and fixed film systems
(e.g., trickling filter, biotower).
III. OTHER
Publicly Owned Treatment Works (POTW) - encompasses any device or
system used in the treatment (including recycling and reclamation) of
municipal or industrial wastes of a liquid nature, that is owned by a State
or municipality, including sewers, pipes, or other conveyances if they
convey wastewater to a facility providing treatment.
