How to Use the NPL Book
The site fact sheets presented in this book
are comprehensive summaries that cover a
broad range of information. The fact sheets
describe hazardous waste sites on the NPL and
their locations, as well as the conditions
leading to their listing ("Site Description").
The summaries list the types of contaminants
that have been discovered and related threats
to public and ecological health ("Threats and
Contaminants"). "Cleanup Approach" pres-
ents an overview of the cleanup activities
completed, underway, or planned. The fact
sheets conclude with a brief synopsis of how
much progress has been made in protecting
public health and the environment. The
summaries also pinpoint other actions, such as
legal efforts to involve polluters responsible
for site contamination and community con-
cerns.
The fact sheets are arranged in alphabetical
order by site name. Because site cleanup is a
dynamic and gradual process, all site informa-
tion is accurate as of the date shown on the
bottom, of each page. Progress is always being
made at NPL sites, and the EPA periodically
will update the site fact sheets to reflect recent
actions. The following two pages show a
generic fact sheet and briefly describe the
information under each section.
How Can You Use
This State Book?
You can use this book to keep informed
about the sites that concern you, particu-
larly ones close to home. The EPA is commit-
ted to involving the public in the decision
making process associated with hazardous
waste cleanup. The Agency solicits input from
area residents in communities affected by
Superfund sites. Citizens are likely to be
affected not only by hazardous site conditions,
but also by the remedies that combat them.
Site cleanups take many forms and can affect
communities in different ways. Local traffic
may be rerouted, residents may be relocated,
temporary water supplies may be necessary.
Definitive information on a site can help
citizens sift through alternatives and make
decisions. To make good choices, you must
know what the threats are and how the EPA
intends to clean up the site. You must under-
stand the cleanup alternatives being proposed
for site cleanup and how residents may be
affected by each one. You also need to have
some idea of how your community intends to
use the site in the future, and you need to know
what the community can realistically expect
once the cleanup is complete.
The EPA wants to develop cleanup methods
that meet community needs, but the Agency
only can take local concerns into account if it
understands what they are. Information must
travel both ways in order for cleanups to be
effective and satisfactory. Please take this
opportunity to learn more, become involved,
and assure that hazardous waste cleanup at
"your" site considers your community's
concerns.

Site Description
The Barkhamsted-New Hartford Landfill encompasses 98 acres near the Barkhamsted and New
Hartford town line. Since 1974, it has been owned and operated by the Regional Refuse Disposal
District One. The unlined landfill accepted municipal and industrial wastes, including oily metal
grindings and sludge containing heavy metals. A barrel-crushing operation to reclaim metals was
also located on site. In 1983, leaking drums containing hazardous solvents were observed on site
during a State inspection. Tests indicated volatile organic compounds (VOCs) were present in
shallow and deep wells on site. An unnamed brook borders the site to the southwest and the
north and flows through a wetland to the Farmington River. The surrounding area is rural and
residential. Many private wells and a municipal water supply well serving an estimated 4,800
people are located within 3 miles of the site. The site was closed under State solid waste
regulations.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 10/04/89
Threats and Contaminants
The groundwater underlying the site is contaminated with VOCs including xylene,
toluene, and vinyl chloride, all of which are present in shallow and deep wells. The
site is not completely fenced, making it possible for people and animals to come into
contact with hazardous substances. Potential public health threats include accidentally
ingesting or coming into direct contact with the groundwater or surface wastes. A
wetland near the site could be threatened by contamination.
July 1995
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: The Farmington Valley Health District shut down the on-site well
serving the landfill office due to VOC contamination.
Entire Site: An investigation into the nature and extent of site contamination began
in late 1991 and is expected to be completed in 1996. A final cleanup remedy for
groundwater contamination is expected to be selected in 1996.
Environmental Progress
The EPA has studied the conditions at the Barkhamsted-New Hartford Landfill site and has
determined that since the contaminated water source has been removed from service, no other
initial actions are required while final cleanup actions are being planned.

Betkoski's Dump
The Beacon Heights Landfill site covers 34 acres on an 83-acre property. Between 1920 and
1979, the landfill was used for the disposal of industrial and municipal waste, including oils,
chemical liquids, sludges, solvents, rubber, and plastics. Landfill operations included open
burning, along with burial of non-combustibles. During an EPA investigation conducted in 1984,
benzene and several other solvents were detected in two private wells on Skokorat Road at levels
that exceeded drinking water standards set by the State of Connecticut. Approximately 44 homes
are located within 1/2 mile of the site along Skokorat and Blackberry Hill Road. The nearest
residences lie approximately 1,000 feet to the north and west of the site; 800 people live within a
mile of the site. Local residences used groundwater as the drinking water supply source until they
were connected to the municipal water supply in 1989. The local surface water is used for
recreational purposes. Hockanum Brook, located 1/2 mile northwest of the landfill, flows into the
Naugatuck River 2 miles northwest of the site. An apple orchard is located approximately 600
feet northwest of the landfill.

Threats and Contaminants
ZEJ
The groundwater underlying the site was found to be contaminated with volatile
organic compounds (VOCs) including methylene chloride. The on-site leachate and
soils are contaminated with VOCs, as well as lead. The on-site surface water has been
shown to be contaminated with VOCs. People are at risk by coming into direct contact
with or drinking contaminated surface water or groundwater, breathing potentially
contaminated air, or by accidentally ingesting soil on the site.
June 1995
-------
Cleanup Approach
The site is being addressed in two long-term remedial phases focusing on control of
contamination sources and cleanup of the leachate at the site.
Response Action Status
Source Control: In 1985, the EPA chose the following remedies: excavating
Betkoski's Dump and other contaminated soils for consolidation with the main landfill
prior to closing it down; fencing the perimeter of the site; covering the consolidated
wastes to prevent contaminant migration; providing gas venting and stormwater management
controls; and installing a system to collect leachate along the perimeter of the site. The potentially
responsible parties completed the cleanup in 1989. State and local control of the use of
groundwater in the area is now being enforced. Connection to the municipal water line was made
available, and 49 residences elected to connect to it. Three pumping stations and a reservoir have
been built to accommodate the additional water service needs.
Leachate: Under the EPA's guidance, a study of leachate disposal was completed by
the potentially responsible parties. The remedy chosen by the EPA for this area
includes excavating leachate for off-site disposal and capping the site. More extensive
groundwater monitoring is planned as well. In the spring of 1992, the potentially responsible
parties completed the design of the remedy and began conducting the cleanup activities. Cleanup
activities are expected to be completed in the fall of 1995.
Site Facts: In 1987, 32 of the more than 70 companies identified by the EPA as potentially
responsible parties agreed to pay for a substantial portion of the site cleanup.
Environmental Progress
Excavating contaminated soil, covering wastes, installing gas venting and leachate collection
systems, and connecting residences to the municipal water line have provided a safe drinking
water supply and reduced the potential for exposure to contamination, making the Beacon Heights
Landfill site safer while final cleanup activities are being completed.

Cjheshire Associates Property
The 15-acre Cheshire Ground Water Contamination site in Cheshire has been leased by a number
of tenants who have conducted various manufacturing processes. A major portion of the site has
been owned by Cheshire Associates, a New York-based partnership, since 1966. The company
leased the property to Valley National Corporation from 1966 to 1979 and to Cheshire Molding
Co. from 1979 to 1980. Both companies manufactured plastic molding at the site; neither kept
records of disposal practices or waste quantities. Airpax Corporation Plant 2, the current lessee,
manufactured electrochemical and electronic devices, beginning in 1983, and disposed of its
wastes in accordance with the State regulations at that time. The wastes of principal concern at
the site include organic chemicals and solvents. Both soil and ground water on the site are
contaminated with volatile organic compounds (VOCs), as are on- and off-site residential wells,
on-site shallow wells, and an off-site bedrock well. The area is residential and industrial. About
330 people living within 1 mile of the site use private wells for drinking water. Cheshire
municipal wells, serving 22,900 people, lie 2 miles southeast of the site.

The ground water is contaminated with VOCs from the organic chemicals and solvents
formerly used at the site. Wells are polluted with VOCs, including high levels of
trichloroethane, dichloroethylene, tetrachloroethylene, and xylenes. VOCs
contaminating the soil also include trichloroethane, dichloroethylene, and
tetrachloroethylene. People who drink contaminated ground water or come into direct
contact with contaminated soil are at risk. The site is in a low-lying, freshwater
wetland bordered by two ponds.
July 1995
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: In October 1983, in compliance with a State Consent Agreement,
Cheshire Associates removed 20 cubic yards of contaminated soil to an
EPA-regulated landfill. Municipal water supplies have been provided to the
Entire Site: An investigation into the nature and extent of contamination at the site
is scheduled to begin in 1996. This investigation will identify cleanup strategies and
lead to the selection of a final remedy.
Site Facts: In 1983, the Connecticut Department of Environmental Protection signed a Consent
Agreement with Cheshire Associates, requiring the company to remove contaminated on-site soil
and to monitor VOCs in the two private wells for five years.
Environmental Progress
The removal of contaminated soil and the provision of a safe drinking water supply have reduced
the potential for exposure to contaminated drinking water at the Cheshire Ground Water
Contamination site, making it safer while site investigations are being planned.

Merriam Mfg.
Site Description
Investigations at the Durham Meadows site are focusing on several sources of contamination,
including the Merriam Manufacturing Company and the Durham Manufacturing Company, both
located on Main Street. The Merriam Manufacturing Company, which occupies 5 acres on Main
Street, was established in 1851. The company makes metal displays and boxes. The Durham
Manufacturing Company was established in 1922 and also manufactured metal boxes.
Contaminated wastewater and sludges were disposed of in two unlined and undiked lagoons
between 1973 and 1982. Paint wastes and degreasing solvents were stored on the ground in
drums. Some were in poor condition or were discovered to be leaking during a State inspection
in 1981. In early 1983, after an EPA/State inspection, the EPA ordered the owner to correct
several violations of State hazardous waste management regulations. In response, Merriam
removed drums and supplied bottled water to affected residents. Durham has a population of
approximately 5,600 residents, all using private wells. Rural residential, commercial, and light
industrial properties surround the area of concern; however, the exact boundary of contamination
is not currently known. The nearest residence lies only 10 feet away from the site's border. The
site is less than Vz mile from the Coginchaug River, which drains into the Connecticut River. A
freshwater wetland is location within 1,500 feet of the site.
Site Responsibility:
The site is being addressed through
Federal, State, and potentially

NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 10/04/89
Threats and Contaminants
Wastewater and sludges from manufacturing processes at the site contained paint
waste and organic solvents. In 1982, the State Department of Environmental
Protection detected volatile organic compounds (VOCs), including methylene chloride,
in private wells in the Durham area. Drinking contaminated ground water may threaten
the health of nearby residents. Certain areas of the site currently lacks any security or
physical barrier to prevent direct contact with contaminated soils. The nearby
freshwater wetlands could potentially become polluted from the contaminants
migrating from the site.
July 1995
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: Under State order, Merriam removed drums containing hazardous
wastes to an EPA-approved facility, and supplied bottled water to residents in the
vicinity of the site after the private wells were found to be contaminated. Carbon
filters have since been installed in affected homes and are regularly monitored under State Order.
Entire Site: An investigation into the nature and extent of groundwater contamination
is scheduled to begin in 1995. This investigation will identify alternative cleanup
strategies and lead to the selection of a final cleanup remedy.
Site Facts: In early 1993, the State ordered Merriam Manufacturing to supply bottled water to
residents in the vicinity of the site. The EPA issued an Administrative Order, requiring Merriam
to correct several violations of State hazardous waste management regulations.
Environmental Progress
Installing carbon filters on drinking water wells and removing some hazardous materials have
reduced the potential for exposure to contaminants at the Durham Meadows site, making it safer
while site studies are completed. Affected drinking water wells are monitored regularly, and the
State continues to monitor other wells in the area.

Site Description
Gallup's Quarry is a 22-acre abandoned gravel pit located in a rural area on Tarbox Road, 1 mile
south of Plainfield's business district. In the 1970s, the owner accepted chemical wastes without a
permit. Drums and free liquids were dumped at the site, including wastes containing volatile
organic compounds (VOCs) and heavy metals. Several of these contaminants were detected in
on-site monitoring wells operated by the State from 1978 to 1981, and by the EPA in 1986. In
1989, the EPA sampled private drinking water wells and found no contamination. The area is
rural and residential. Approximately 6,500 people rely on wells located within 3 miles of the site
as their sole source of drinking water. A community well is located 4,000 feet away, and the
nearest private well is located 1,160 feet from the site.

Threats and Contaminants
The groundwater is contaminated with VOCs and heavy metals, including copper,
nickel, and chromium. Ketone and hydrocarbons have been found in the soil. Access
to the site is currently unrestricted. Direct contact with hazardous substances on site
may pose a health threat. Mill Brook and associated wetlands, located 500 feet
downgradient of the site, are threatened by site contamination. Local residents use
these resources for recreational purposes.
June 1995
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: In 1978, the site was evaluated by the Connecticut Department of
Environmental Protection. The State environmental staff and the State Police
supervised the removal of waste drums and contaminated soil. The owner agreed to
reimburse the State for the removal activities at Gallup's Quarry and at another property that he
owned. However, limited soil analyses conducted by the State in 1981 indicated that contaminants
still remained on the site. Further definition of the remaining contaminants will occur as part of
the site-wide investigation described below.
Entire Site: The potentially responsible parties are currently investigating the nature
and extent of soil and groundwater contamination. Based on the results of this study,
the EPA will recommend cleanup alternatives for the site. Completion of the study
and final selection of a cleanup remedy is scheduled for early 1996.
Site Facts: An EPA Administrative Order on Consent was signed with the parties potentially
responsible for site contamination in September 1993 to conduct the site investigation and to
evaluate potential cleanup alternatives.
Environmental Progress
Removal of waste drums and contaminated soils has reduced the risk of accidental exposure to
contamination, making the site safer while investigations leading to further cleanup actions are
currently underway.

Smith Well Field
Site Description
The Kellogg-Deering Well Field site consists of an approximately 10-acre municipal well field
and adjacent areas that contribute to the well field contamination. Groundwater sampling data
indicated that a significant source of contamination exists below the Elinco/Pitney Bowes/Matheis
Court Complex located at the eastern edge of the site. The well field supplies approximately 25
percent of the drinking water to 45,000 residents in the City of Norwalk. The primary source of
public water supply to the Norwalk First Taxing District (NFTD) Water Department is surface
water from four reservoirs. Reservoir water is blended with well field water at varying ratios,
depending on reservoir storage and distribution system location. The well field is adjacent to
residential and industrial areas.
Site Responsibility:
The site is being addressed through
Federal, State, and potentially
responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 09/08/83
Final Date: 09/21/84
Threats and Contaminants
The groundwater and soil are contaminated with volatile organic compounds (VOCs),
primarily trichloroethylene (TCE) and perchloroethylene (PCE). People could be
exposed to chemical contaminants by drinking contaminated water if no treatment
were provided; however, the water department is treating and blending water from the
wells and reservoir to provide safe drinking water.
July 1995
-------
Cleanup Approach
The site is being addressed in three long-terra remedial phases focusing on wellhead treatment,
source control, and downgradient aquifer management.
Response Action Status
Wellhead Treatment: The Water Department installed an aerator in 1981 at one of
the wells. The aerator consistently removes 65 percent of the volatile organics in the
groundwater. In 1984, NFTD installed an air stripper on another well, bringing the
removal of VOCs to 99 percent. Air filtering actions were completed in 1988. The air stripper is
part of the water treatment plant and will remain in operation. Contaminants have been removed
from the water by air filtering the volatile contaminants into a gaseous state. The treated water is
discharged into the existing conventional water treatment plant and distribution system.
Source Control: The remedy selected by the EPA for controlling the source of
contamination involves removal of contaminants from the soil with vacuum extraction,
treatment and discharge of contaminated groundwater, and institutional controls to
prevent exposure during the time that the remedy is being conducted. Air and groundwater
monitoring also will be provided. Design of the cleanup was completed in late 1994.
Construction of the remedies began in late 1994 and is scheduled to be completed in late 1995.
Downgradient Aquifer Management: In 1990, the EPA began an investigation
into the nature and extent of contamination of areas downgradient from the source and
above the well field. The study will evaluate the impact of the cleanup at the well
head and source control areas on reducing the levels of contaminants downgradient from the
source and above the well field.
Site Facts: In 1987, an EPA Administrative Order was issued to one of the potentially
responsible parties to ensure wellhead treatment. In 1990, EPA signed a Consent Decree with
four potentially responsible parties to design and implement source control cleanup activities. The
current owners of the source area property are operating a separate groundwater extraction and
treatment system under order by the Connecticut Department of Environmental Protection. This
treatment system will continue to operate concurrently with the supplemental cleanup activities
being implemented under the 1990 Consent Decree.
Environmental Progress
Wellhead treatment actions have eliminated the potential of exposure to hazardous substances in
the drinking water and will continue to protect the neighboring residents while planned cleanup
activities at the Kellogg-Deering site are completed.

Murthas Hunter Mountain Landfill
Laurel Park Landfill
Site Description
The Laurel Park, Inc. site is a landfill that occupies approximately 20 acres of a 35-acre parcel of
land. The landfill has been in existence since the late 1940s, and several industries disposed of
solvents, oils, hydrocarbons, chemical and liquid sludge, chemical solids, tires, and rubber
products there. The facility continued to operate as a municipal landfill until 1987. The centrally
developed portion of the Town of Naugatuck, which has an estimated population of 26,500
people, is located approximately 1 mile northeast of the site. Homes are located around three
sides of the landfill. Approximately 50 homes are located within a 1/4-mile radius of the site,
with the closest residents being about 1,000 feet from the site. The nearest homes used
ground water from private wells as a drinking water source, but have since been connected to the
public water supply. The homes at the bottom of Huntington Hill, downslope of the landfill, are
served by a public water supply line. Most of the area immediately bordering the site is forested.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.

Threats and Contaminants
ZGJ
The on-site soil and leachate are contaminated with inorganic and organic chemicals
including dichloroethane and benzene. Groundwater and surface water are
contaminated with heavy metals, including calcium and magnesium, and volatile
organic compounds (VOCs) such as toluene and acetone. Health threats include
coming into direct contact with, drinking, or accidentally ingesting contaminated
groundwater, surface water, soils, and leachate. Forested areas surrounding the site
may be threatened by runoff of site contamination.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases.
focusing on fencing a portion of the site, installing a water line, and building a sewer and source
control and groundwater treatment.
Response Action Status
Initial Actions: Under a court order, a leachate collection system was built in 1984
to capture contaminants leaching from the landfill area into the groundwater and
other site areas. Additionally, the potentially responsible parties provided bottled
water to area residents affected by the contaminated drinking water supply.
Fencing, Water Line, and Sewer Treatment: The potentially responsible
parties fenced a leachate seep in 1986 and installed a water supply line in 1989. The
water line is completed. All of the homes are hooked up, with the exception of three
residences whose owners refused to be connected to the system. There is no hook-up fee, but the
homeowners do have to pay for municipal water use. The potentially responsible parties built a
sewer line in 1990 to carry leachate from the site to the Naugatuck Water Pollution Control
facility for treatment.
Source Control and Groundwater Treatment: The remedy selected by the
EPA to control the source of contamination and to treat groundwater includes:
installation of a synthetic cap over all waste disposal areas to prevent contact with
surface water and groundwater; rehabilitation of the existing leachate collection system, possibly
including the addition of a system consisting of french drains and groundwater extraction wells,
followed by off-site treatment and discharge at the Naugatuck Water Pollution Control Facility;
monitoring of the air, water, soils, and groundwater at the site; and installation of a permanent
fence around the perimeter of the site following the completion of the cap and landscape grading.
Preparation of the design and technical specifications for the selected remedies are underway and
expected to be completed in 1995.
Site Facts: In the early 1960s, citizens began to complain about odors, fires, spills, and runoff
from the site. In 1985, Uniroyal Chemical Company, Inc., a potentially responsible party,
entered into an Administrative Consent Order with the EPA to conduct an investigation into the
type and extent of contamination at the site. In 1987, the EPA issued an Administrative Order on
Consent to potentially responsible parties for construction of a water line. In 1989, the State and
Uniroyal agreed to equally fund the installation of a sewer line to convey leachate from the
landfill. In 1991, 19 potentially responsible parties signed a Consent Decree and the
accompanying Administrative Order to conduct the technical design of the remedy.

Environmental Progress
Initial actions to provide safe drinking water and to control leachate from the landfill have
reduced the immediate threats at the Laurel Park, Inc. site. Additional cleanup actions and the
planned groundwater treatment will further reduce contamination levels at the site, making it safe
to the nearby residents and the environment.

Plaine Hill Road in Woodstock
Site Description
The 45-acre Linemaster Switch Corporation site has been used to manufacture electrical and
pneumatic foot switches and wiring harnesses since 1952. Facility operations involve the use of
trichloroethylene (TCE), paint, and thinners. Wastes are stored in barrels inside of sheds near the
factory building. The site boundary has been expanded to 92 acres, due to the spread of
contamination, extending to Route 171 to the south, Plaine Hill Road to the west, and Route 169
to the north and east. Approximately 2,100 people live within 3 miles of the site and obtain
drinking water from wells drawing on the contaminated ground water. An on-site well supplies
drinking water to the factory and its offices. The site is surrounded by the Town of Woodstock, a
rural community of approximately 5,300 people. Artificial ponds located on the site are used for
boating.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 02/21/90
Threats and Contaminants
Groundwater, sediments, surface water, and soils are contaminated with TCE. TCE
was also detected in Linemaster's main pump house well, which supplies drinking
water to the factory and its offices. Solvents were detected in the artificial ponds. The
site is unfenced, making it possible for people and animals to come into direct contact
with hazardous substances. Other public health threats include drinking contaminated
ground water and coming into direct contact with the soil, surface water, and
sediments.
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
June 1995
-------
Response Action Status
Initial Actions: Linemaster began providing bottled water to its employees in 1986.
Also in 1986, the EPA began to provide bottled water to off-site residents whose
wells were contaminated. Currently, all bottled water is provided by Linemaster.
Linemaster's main production well has been equipped with an air stripper to remove ground water
contaminants, and the well now supplies drinking water to the factory and one on-site residence.
Several other contaminated wells, located on and off site, have been equipped with carbon filter
treatment systems to remove contaminants. A water supply monitoring program has been
established for on- and off-site wells. Monitoring wells have been drilled to determine the extent
of site contamination and to aid in developing a cleanup remedy. In addition, the parties
potentially responsible for site contamination have installed a groundwater extraction and
treatment system to eliminate the contamination threat.
Entire Site: In June 1993, following the completion of an extensive site-wide
investigation and a public comment period, the EPA selected a remedy to address the
contaminated soil and groundwater. The remedy includes the use of a soil vapor
extraction system with carbon controls as well as a system of groundwater extraction wells
connected to an air stripper with emission controls. Design of the remedy began in late 1994 and
is expected to be completed in 1995.
Site Facts: In 1986, the Connecticut Department of Environmental Protection issued an
Abatement Order, requiring Linemaster to develop a plan for a hydrological study to determine
the nature and extent of contamination. In 1987, Linemaster and the EPA entered into a Consent
Order for the company to provide bottled water off site, monitor residential wells, and conduct a
hydrogeologic study.
Environmental Progress
Supplying bottled water to affected residents and Linemaster Switch Corp. employees has reduced
the potential for exposure to hazardous substances in the drinking water. During 1993, the
existing groundwater extraction and treatment system contained the contaminated groundwater
plume within the Linemaster property boundaries. Since that time, TCE in off-site residential
wells has not exceeded drinking water standards.

DOD/USN SB/Area A Landfill #2
Site Description
The New London Submarine Base site covers 576 acres of the 1,412 acre base on the eastern
bank of the Thames River in Groton. The base was established in 1868 as an operation and
support base for submarine activities in the Atlantic Ocean since 1916. Areas of concern include
the Area A Landfill, the Over Bank Disposal Area, the Defense Reutilization and Marketing
Office (DRMO), the Lower Submarine Base, and the Goss Cove Landfill. From 1957 to 1973,
volatile organic compounds (VOCs), pesticides, poly chlorinated biphenyls (PCBs), spent battery
acids, and other wastes were buried below the water table in the 11-acre Area A Landfill, which
is situated adjacent to wetlands. The Over Bank Disposal Area was created sometime after an
earthen dam was built in 1957. The DRMO was used as a burning ground and landfill from 1950
to 1969 and is currently used as a temporary storage area. Inspection reports from 1982 recorded
leaking containers and evidence of spills associated with containers stored directly on the ground.
In 1983, approximately 40 gallons of PCB-contaminated oil were reported to have been spilled
onto the ground. In 1988, Navy sampling revealed lead, cadmium, and various pesticides in
sediments and surface water. The area around the base is mixed industrial, commercial, and
residential property. Groundwater in some areas of the base is as shallow as 10 feet below the
surface, with permeable soils. These conditions potentially threaten the area groundwater. The
population within 1 mile of the base is 4,000.
Site Responsibility:
The site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 10/26/89
Final Date: 08/30/90
Threats and Contaminants
The soil, sediments, and surface water are contaminated with pesticides and heavy
metals including cadmium and lead. The soil also contains VOCs, PCBs and
polycyclic aromatic hydrocarbons (PAHs). The site is a restricted-access Naval base,
so the chance of direct contact with on-site sediments, soil, or surface water is
minimal.
July 1995
-------
Cleanup Approach
The site is being addressed in five long-term remedial phases focusing on cleanup of the Area A
Landfill, the Over Bank Disposal Area, the DRMO Area, the Lower Sub Base, and other
contaminated areas of the base.
Response Action Status
Area A Landfill: In 1990, the Navy began an investigation into the nature and extent
of VOC, pesticide, battery acid, and other contamination at the Area A Landfill.
While in operation, the landfill accepted all non-salvageable materials. Leachate from
the landfill drains into the area wetland and is ultimately carried downstream and discharged into
the Thames River. The second phase of this investigation is currently underway. When the study
is completed, expected in the fall of 1995, cleanup alternatives will be identified and a cleanup
remedy will be chosen. The Navy is currently evaluating interim cleanup actions at this location.
Over Bank Disposal Area: In 1990, the Navy began an investigation into the
nature and extent of contamination at the Over Bank Disposal Area. When the study is
completed, scheduled for 1996, cleanup alternatives will be identified and a final
remedy will be chosen. The Navy is currently evaluating interim cleanup actions at this location.
DRMO: In 1990, the Navy began a study into the nature and extent of contamination
at the DRMO Area. Initial findings detected high to moderate levels of contaminants
in the soil samples analyzed; low contaminant levels were detected in the
groundwater. The second phase of this investigation is currently underway. Upon completion of
the investigation, scheduled for 1997, a final cleanup remedy will be selected. In winter 1994, as
an interim cleanup remedy, the Navy removed PCB- and lead-contaminated soil, backfilled the
area with clean fill, and placed an impermeable cap over the area. The removal action is
currently being evaluated for its long term effectiveness.
Lower Sub Base: In 1990, the Navy began an investigation into the nature and
extent of contamination at the Lower Sub Base. Petroleum products have been
observed in several man holes. The exact source of these releases is still being
investigated, although it appears to be from underground fuel lines or storage tank leaks. The
final cleanup remedy will be chosen when the study is completed, scheduled for 1997.
Other Areas: In 1993, the Navy began an investigation into the nature and extent of
contamination in other site areas. The site areas being investigated include: CBU
Drum Storage Area; Rubble Fill at Bunker A-86; Torpedo Shops, Buildings 325 and
450; Gross Cove Landfill; Over Bank Disposal Area Northeast; Spent Acid Storage and Disposal
Area; and a Former Gasoline Station. Once the investigations are completed, the EPA and the
State will evaluate the study results to determine the most appropriate cleanup remedies.
Site Facts: The base is participating in the Installation Restoration Program, a specially funded
program established by the Department of Defense (DOD) hi 1978 to identify, investigate and
control the migration of hazardous contaminants at military and other DOD facilities.

Site Description
The investigation of the Nutmeg Valley Road site centers around Nutmeg Screw Machine
Products Company (NSMP), which covers 3l/2 acres on Nutmeg Valley Road. The area around
the site is both rural residential and light industrial, with several other metal-working and
metal-finishing shops in the immediate vicinity, including Waterbury Heat Treating Corporation
(WHTC) and Alpine Electronic Components, Inc. (AEC). WHTC is located 300 feet to the
northwest of NSMP and performs various heat-treating operations (annealing and hardening) on
metal parts and degreasing, polishing, acid dipping, and assembly functions. AEC leases part of
the NSMP building. The NSMP is a small metal-working and machine shop that has been in
business since 1951. Substances used in the machining processes include a kerosene-like cutting
oil, machine lubrication oils, and agents used for cleaning and degreasing, such as carbon
tetrachloride. Carbon tetrachloride, cyanide wastes, and cutting oils were dumped onto the
ground at an estimated rate of up to 15 gallons per day, according to the State. This practice was
followed for approximately 14 to 20 years, ceasing by 1980. Approximately 10,500 people draw
drinking water from private wells within 3 miles of the site. There are 43 industries and 25
residences using groundwater as a drinking water source at this site. The Towns of Waterbury,
with a population of approximately 103,800, and Wolcott, with a population of approximately
13,200 lie within 3 miles of the site.

Cleanup Approach
The site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Immediate Actions: The State has been supplying bottled drinking water to
affected residents since 1987. Also, carbon filters have been installed on the
industrial wells to reduce contamination levels. Interim measures have included the
extension of public water supplies to the area, and removal of some contaminated soil from a
lagoon on site.
Entire Site: The EPA plans to conduct an investigation into soil and groundwater
contamination at the site and develop strategies for final cleanup. The study is
scheduled to begin in 1997. Upon completion, the EPA will evaluate the study's
findings and select the final cleanup remedies.
Environmental Progress
The initial actions described above have provided safe drinking water to affected residents and
reduced contamination levels in the industrial water supply, limiting the threat of exposure while
the investigation leading to final cleanup is being planned at the Nutmeg Valley Road site.

Site Description
The Old Southington Landfill is a 11-acre site that may have been used as early as the 1920s
until 1967 as a municipal disposal area. During this time, the landfill was open to residents and
businesses of the Town. In 1967, the Town of Southington closed the landfill. Closure
procedures included compacting loose refuse, covering the landfill with at least 2 feet of clean fill
material, and reseeding with grasses. Between 1973 and 1980, the landfill was subdivided and
sold for residential and commercial development. Several residential and commercial structures
now occupy the closed landfill and adjacent areas. The former landfill is located approximately
700 feet southeast of the former municipal Well No. 5, which was installed in 1971 by the Town
of Southington Water Department as a public water supply. In 1979, the municipal well was
closed because groundwater analyses indicated the presence of volatile organic compounds
(VOCs) at levels that exceeded State standards. The well has permanently been closed. The site is
located about 1800 feet to the east of the Quinnipiac River.

July 1995
-------
Cleanup Approach
The site is being addressed in a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status
Entire Site: The potentially responsible parties completed the site investigation in late
1993. The investigation defined the contaminants and recommended alternatives for
the final cleanup. EPA selected an interim cleanup remedy in September 1994. The
interim remedy consists of capping the site, excavating and consolidating a "hot spot" in a lined
cell on site, removing all buildings from the landfill, installing a soil gas collection/treatment
system, and performing long term monitoring of soil gas, groundwater, surface water, and
sediment. Also, additional groundwater studies will be performed to determine the extent of
contamination of the plume and determine if it may be adversely impacting any downgradient
natural resource areas. The EPA will evaluate the results of these studies in conjunction with
those of the long term monitoring program and select a final groundwater remedy, as necessary.
Site Facts: In 1987, the EPA issued an Administrative Consent Order to three parties
potentially responsible for the contamination of the site to perform a study to determine the
nature and extent of contamination at the site, determine potential risks to the public and the
environment, and evaluate feasible remedial alternatives for the site's cleanup. In January 1993,
320 new parties were named as potentially responsible. All parties are expected to participate in
future work relating to groundwater studies and implementation of the interim remedy.
Environmental Progress
After adding this site to the NPL, the EPA assessed conditions at the site and determined that
contamination from the Old Southington Landfill site currently does not pose an immediate threat
to area residents and surrounding environments, and no emergency actions were required to make
it safe while waiting for cleanup actions to begin. An interim remedy has been selected for the
site which will address all contaminated media except for groundwater. Groundwater
contamination will be addressed in the final remedy for the site.

rinsing, buffing, and polishing. Wastes generated during this process include rinse waters
containing heavy metals, batch wastes of alkaline cleaner, and spent plating and etching acids.
Before 1983, rinse waters were discharged to a storm drain outside the building. Process plating
acids and chrome plating wastes were stored on the ground in drums and in a 500-gallon tank. In
1979, Vernon's Health Department found the well serving Hillside Industrial Park to be
contaminated with hexavalent and trivalent chromium. The rupturing of drums and the tank by a
snow plow was determined to be the cause of contamination. The company, and later the EPA,
confirmed that the groundwater underlying the site had become contaminated. An estimated
10,800 people obtain drinking water from public and private wells located within 3 miles of the
site. Surface waters in the area are used for recreational fishing. The site is located within 1 mile

Site Description
EPA REGION 1
Fairfield County
Stratford
The Raymark Industries, Inc. site encompasses a 33 acre industrial parcel of property located at
75 East Main Street in Stratford, Connecticut. The manufacturing waste byproducts from
Raymark were also used for fill on numerous residential, commercial, and municipal properties
throughout Stratford. These historic filling activities primarily occurred within several wetland
areas in close proximity to the Housatonic River. The property was used as a manufacturing
facility for brakes, clutch parts, and other friction products by Raymark Industries Inc. and its
predecessors from 1919 until it ceased operations in 1989. The facility is located adjacent to
Interstate 95 in an area which includes many industrial, commercial, recreational, and residential
properties. The facility operated as a hazardous waste generator and land disposal facility,
regulated under Subtitle C of the Resource Conservation and Recovery Act (RCRA).
Polychlorinated biphenyls (PCBs), dioxin, semi-volatile and volatile organic compounds (VOCs),
lead-asbestos dust, metals, and solvents were produced on site. From 1919 to 1984, Raymark
used a system of lagoons to capture wastes produced by its manufacturing process. Dredged
materials from the lagoons were landfilled at numerous off-site locations, including an adjacent
ballfield, residential, and municipal properties. The Connecticut Department of Environmental
Protection (CT DEP) and the EPA conducted extensive surficial sampling of the site in 1993.
Based upon the detection of elevated concentrations of lead, asbestos, and polycholorinated
biphenyls (PCBs) in surficial soil, the Agency for Toxic Substances and Disease Registry
(ATSDR) issued a public health advisory on May 26, 1993. The total population within 4 miles
of the site is approximately 145,000. No known public drinking water wells are located within 4
miles of the site; however, a few private drinking water wells may exist upgradient of the
facility. Ferry Creek, the Housatonic River, and Long Island Sound are located downstream from
some of the disposal areas. Seed oysters are cultivated in this area of Long Island Sound and
crabs and clams may also be recreationally harvested. The Raymark property currently includes a
number of former waste lagoons and vacant buildings. The site was built up over many years
using manufacturing waste-by products for fill. Site drainage discharges into a storm sewer which
eventually discharges into Ferry Creek which flows 1/2 mile into the Housatonic River.

Threats and Contaminants
Lead, asbestos, PCBs, semi-VOCs, VOCs, and solvents have been detected in on-site
soils. Groundwater is contaminated with heavy metals, chlorinated solvents, semi-
VOCs, and VOCs. Ingesting or coming into contact with these contaminants could be
harmful to public health. An advisory was issued by the Agency for Toxic Substances
and Disease Registry based on the concern that people could be exposed to site-related
contaminants through inhalation of, direct contact with, and ingestion of waste present
in the soil, and consumption of potentially contaminated seafood. No current human
health threat is posed by the groundwater contamination on and near the site since it is
not currently used for drinking water purposes.
Cleanup Approach
The site is being addressed in four stages: initial actions and three long-term actions focusing on
source control, groundwater, and the ecological area.
Response Action Status
Initial Actions: During the summer of 1992, the EPA built a temporary cap on a
portion of the commercial property known as the Raybestos Memorial Field.
Railroad tracks separate the commercial facility from the Raymark Industries, Inc.
facility. The EPA excavated contaminated waste/soil from approximately 40 residential properties
during the fall of 1993. This contaminated material was transported back to the Raymark
Industries, Inc. facility for temporary storage. The contaminated materials being stored at the
Raymark facility will be addressed as part of the cleanup action selected for the Raymark
Industries, Inc. property. Additionally, throughout 1993, Raymark undertook a number of interim
actions at its 75 East Main Street facility, including removing thousands of 1 1/2 cubic yard bags
of asbestos and containers holding hazardous substances, temporarily capping four waste lagoons,
and securing the facility. Finally, the CT DEP has undertaken an number of interim actions on
municipal properties between 1993 and 1994, including installing temporary caps and fencing at
the Wooster Jr. High School and a portion of what is known as Short Beach Park. Also during
1994, the CT DEP required several commercial property owners to restrict access to known
contaminated waste areas through the installation of fences or pavement.
Source Control: The EPA began an investigation into the nature and extent of the
source of contamination in late 1994. Upon its completion, scheduled for late 1995,
a final cleanup remedy will be selected.
Groundwater: The EPA began an investigation into the nature and extent of
groundwater contamination in late 1993. Upon its completion, scheduled for 1995, a
final cleanup remedy will be selected.

The EPA, working cooperatively with the CT DEP, the town, and commercial property owners,
has taken extensive immediate actions to protect public health by excavation of wastes from
residential areas, interim capping of wastes and fencing at municipal properties, and restriction of
access at commercial properties. The interim actions to stabilize waste at the site are keeping the
Raymark Industries site safe while studies leading to final cleanup are underway.

Site Description
The Revere Textile Prints Corporation site covers 15 acres in a town-owned industrial park. The
textile processing facility first operated over 50 years ago as the U.S. Finishing Company. In
1978, Revere Textile was allegedly observed dumping barrels of wastes into the Moosup River.
The facility was destroyed by fire in 1980. Following the fire, a number of drums were evident
in the ruins of two buildings on site. The property was sold after the fire in 1980. On site at the
time were over 1,500 drums that leaked dyes, paints, solvents, and heavy metals onto the
ground. The State detected over 30 compounds in the drums and soil on site and issued an order
against the new owner to clean up the site. In 1982, ownership of the site was transferred to
Sterling Industrial Park Corporation. After several State inspections and rounds of sampling, the
drums were removed in 1983 by the new owner. An unknown quantity of contaminated soil also
was removed. On-site monitoring wells were sampled in 1984 and found to be contaminated. The
site is located in an industrial park with approximately 350 people living within 1 mile of the site
and 4,500 people living within a 3-mile radius. The site is now inactive. The Moosup River is
located downgradient of the site and is used for recreational purposes.

Threats and Contaminants
Ground water was contaminated with antimony, methanol, and volatile organic
compounds (VOCs) including toluene and trichloroethylene (TCE). The soil was
contaminated with barium and VOCs including ethyl benzene and xylene. Before
cleanup actions were initiated, people who accidentally came into direct contact with
or ingested contaminated groundwater or soil may have been at risk. Residents in the
area depend on the groundwater as their sole source of drinking water. However, the
water supply to the residents is not affected by this contamination.

Cleanup Approach
Response Action Status
Immediate Actions: In 1983, more than 1,500 drums containing dyes, paints,
solvents, and heavy metals were removed by the Town of Sterling. In 1990, the town
removed an additional six drums and paint cans from the site that contained solvents,
oils, naphthalene, and VOCs. The Town placed restrictions on land use, specifically excluding
non-commercial development and groundwater use.
Entire Site: In 1992, the EPA completed an investigation into the nature and extent
of site contamination. The EPA reviewed the study findings and determined that, due
to the immediate actions undertaken by the Town, the level of contamination at the
site was no longer harmful to the surrounding population or environment; therefore, no further
action was necessary. The site will be monitored for five years to ensure that the site remains
safe.
Site Facts: In 1980, the State issued an order against the owner to clean up the site. In 1982,
ownership of the site was transferred to Sterling Industrial Park Corp. In September 1983,
Sterling Industrial Park Corp. complied with the 1980 State Order and removed the leaking
drums and an unknown quantity of contaminated soil from the site.
Environmental Progress
The initial actions to remove drums and contaminated soils from the site reduced the potential for
accidental exposure to hazardous wastes at the Revere Textile site. Investigations determined that
the site no longer poses a threat to public health or the environment. Five years of monitoring
will ensure that the immediate actions taken at the site continue to protect public health and the
environment. The site was deleted from the NPL in September 1994.

Site Description
Solvents Recovery Service of New England (SRS) is a fenced 2 1/2-acre facility located in the
Town of Southington. The facility operated as an EPA-approved hazardous waste treatment and
storage facility. The facility received various waste industrial solvents that are blended for use as
a fuel product. From 1957 to 1967, stillbottom sludges were disposed of in two unlined lagoons.
In 1967, sludge disposal was discontinued, and the lagoons were drained and covered with fill.
After the lagoons were closed, wastes were burned in an open pit on site or disposed of off site.
In the 1970s, the State ordered that the incineration practice be discontinued. Past operating
practices on site, such as accidental spills or poor housekeeping, may have constituted additional
sources of contamination. The Town of Southington Well #4 is located approximately 2,000 feet
south of the site, and Well #6 is located 1,300 feet to the south of the site. Both of these wells
were closed in 1979 because of contamination. In 1991, all activities at the site ceased in
preparation for closure under the Resource Conservation and Recovery Act (RCRA). No
hazardous waste disposal currently takes place at the site. The population of Southington is
38,000. The area near the site is a mixture of commercial, light industrial, residential, and some
agricultural uses. The facility is located approximately 500 feet to the west of the Quinnipiac
River.

Threats and Contaminants
The groundwater is contaminated with isopropyl alcohol, acetone, toluene, and other
volatile organic compounds (VOCs). The soil is contaminated with lead, cadmium,
poly chlorinated biphenyls (PCBs), and VOCs. People who accidentally drink
contaminated groundwater may be at risk. However, since the two municipal wells
have been taken out of service, this health threat has been reduced. In addition, direct
contact with or accidental ingestion of contaminated soil may pose a health risk.
Cleanup Approach
The site is being addressed in three long-term remedial phases focusing on cleanup of on-site and
off-site groundwater and source control.
Response Action Status
On-site Groundwater: Under a 1983 Consent Decree, the parties potentially
responsible for the site contamination agreed to pump and treat groundwater in the
operations area by an ultraviolet/oxidation system installed and operated by the
Connecticut Department of Environmental Protection. The treated water subsequently is
discharged through a drainage ditch to the Quinnipiac River. Solvents Recovery Service has
installed the on-site groundwater pumping system, which currently is operational.
Off-Site Groundwater: An interim action is ongoing to contain and treat
contaminated shallow groundwater which is migrating from the operations area, in
addition to performing additional investigations. The potentially responsible parties
began construction of the final cleanup remedy in early 1994 which is scheduled to be completed
by 1999.
Soil: The EPA is conducting an investigation into the sources and the nature and
extent of soil contamination to identify alternatives for cleaning up the site. The
investigation is scheduled to be completed in 1996.
Site Facts: In 1983, Solvents Recovery Service signed a Consent Decree with the EPA
requiring the installation of a system to recover groundwater on and off site and a plan for on-site
storage and management of hazardous wastes. The EPA signed a final Consent Decree with SRS
for settlement of its liabilities with respect to the site in early 1994. In addition, the EPA signed
a Consent Decree with approximately 830 small potentially responsible parties for release of their
liability for the site in late 1994.

Canterbury Township
Site Description
The Yaworski Waste Lagoon is a dewatered and backfilled lagoon, approximately 800 feet by
300 feet and 12 feet deep. From about 1948 to 1973, drummed material and bulk wastes
including textile dyes, solvents, resins, acids, caustics, stillbottom sludges, and solvent-soaked
rags were disposed of in the lagoon. Periodically, flammable liquid waste was burned in several
pits in the lagoon area until 1965, when the Connecticut Department of Health ordered a halt to
on-site burning of waste. The combined efforts of local residents and State and local officials
concerned about adverse human health and environmental effects from disposal operations at the
site led to the end of all dumping at the site in 1973. In 1976, the Connecticut Department of
Environmental Protection (CTDEP) directed the site owner to assess the environmental hazard
posed by the site. The owner was required to install monitoring wells adjacent to the lagoon.
Sampling of these wells detected contaminated groundwater. In 1980, the CTDEP ordered the
site owner to employ a professional engineering firm to conduct an environmental study of the
property. The firm recommended closing the lagoon by covering the waste and, in 1982, the
CTDEP ordered that the lagoon be closed in accordance with the engineering firm's report. After
a fire in 1982, the EPA decided that additional information was needed about the site to better
assess the potential threats to human health and the environment. The population of Canterbury is
approximately 1,600. The nearest residence that uses groundwater is located 1,600 feet
upgradient from the site and across the Quinebaug River. The site is surrounded by agricultural
land and bordered by the Quinebaug River. It lies within the 100-year flood plain.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.

Threats and Contaminants
Groundwater samples taken from the areas immediately adjacent to the lagoon
revealed the presence of volatile organic compounds (VOCs) and heavy metals.
Inorganic contaminants were found in the sediments in the wetlands area just south of
the lagoon. The lagoon soil is contaminated with polychlorinated biphenyls (PCBs)
and polycyclic aromatic hydrocarbons (PAHs). Soil samples taken from areas
immediately adjacent to the lagoon revealed the presence of low levels of VOCs.
Contaminants have also been detected in the Quinebaug River.
Cleanup Approach
The site is being addressed through a long-term remedial phase focusing on cleanup of the entire
site.
Response Action Status
Entire Site: The parties potentially responsible for the site contamination contained
the waste in the lagoon by building an impermeable cover that complied with all
environmental laws; improving the dike around the lagoon, ensuring that it would
withstand floods; establishing a groundwater protection standard known as an Alternate
Concentration Limit (ACL); and monitoring the groundwater for 30 years to confirm that the
ACL standard is met. The lagoon was covered in the summer of 1990. A permanent vegetative
cover was added in 1991. In early 1992, the EPA approved closure of the lagoon. In addition,
monitoring wells were installed in late 1990, 1991, and 1992. The potentially responsible parties
are currently conducting groundwater, surface water, and sediment sampling on site to ensure the
effectiveness of the cleanup actions taken. Additionally, an investigation to address groundwater
contamination across the Quinebaug River is expected to begin in 1995.
Environmental Progress
After adding this site to the NPL, the EPA assessed site conditions and determined that the site
contamination did not pose an immediate threat to area residents and the surrounding environment
while waiting for cleanup actions to be completed at the Yaworski Waste site. The construction
of an impermeable cover and improvements to the dike have eliminated the threat of residents
coming into direct contact with contaminants from the lagoon.
