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
This section describes the location and history of the site. It includes descrip-
tions of the most recent activities and past actions at the site that have con-
tributed to the contamination. Population estimates, land usages, and nearby
resources give readers background on the local setting surrounding the site.
THREATS AND CONTAMINANTS
The major chemical categories of site contamination are noted, as well as
which environmental resources are affected. Icons representing each of the
affected resources (may include air, groundwater, surface water, soil, and
contamination to environmentally sensitive areas) are included in the margins
of this section. Potential threats to residents and the surrounding environ-
ments arising from the site contamination also are described.
CLEANUP APPROACH
This section contains a brief overview of how the site is being cleaned up.
RESPONSE ACTION STATUS
Specific actions that have been accomplished or will be undertaken to clean
up the site are described here. Cleanup activities at NPL sites are divided
into separate phases, depending on the complexity and required actions at the
site. Two major types of cleanup activities often are described: initial,
immediate, or emergency actions to quickly remove or reduce imminent
threats to the community and surrounding areas; and long-term remedial
phases directed at final cleanup at the site. Each stage of the cleanup strategy
is presented in this section of the summary. Icons representing the stage of
the cleanup process (initial actions, site investigations, EPA selection of the
cleanup remedy, engineering design phase, cleanup activities underway, and
completed cleanup) are located in the margin next to each activity descrip-
tion.
SITE FACTS
Additional information on activities and events at the site are included in this
section. Often details on legal or administrative actions taken by the EPA to
achieve site cleanup or other facts pertaining to community involvement with
the site cleanup process are reported here.

Site Description
The Atlas Tack Corporation formerly manufactured cut and wire tacks, steel nails, and similar
items on a 12-acre site in Fairhaven. From the 1940s until the late 1970s, wastes containing
cyanide and heavy metals, including high levels of arsenic, were discharged into an unlined acid
neutralizing lagoon located approximately 200 feet east of the manufacturing building and
adjacent to a saltwater tidal marsh in Buzzards Bay Estuary. Other contaminated areas at the site
include a filled wetland, former dump, and other chemical spills. The area is residential and
commercial. Approximately 7,200 people live within a 1 mile radius, and 15,150 live within 3
miles of the site.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88

Threats and Contaminants
Z1AJ
The groundwater is contaminated with cyanide and toluene that leached from the site
lagoons. The on-site soil is contaminated with volatile organic compounds (VOCs),
including toluene and ethyl benzene, as well as heavy metals, including beryllium,
mercury, nickel; pesticides; and polychlorinated biphenyls (PCBs). Nearby residents
are at risk through direct contact with contaminated soil or ingestion of water from
contaminated wells. The marsh south of the lagoon and estuarine areas in Buzzards
Bay are contaminated.
Cleanup Approach
The site is being addressed in two phases: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
July 1995
-------
Response Action Status
Initial Actions: In late 1992, the potentially responsible party installed a fence
around the site to control access.
Entire Site: The EPA is currently conducting an investigation into the nature and
extent of site contamination. The investigation will identify contaminants of concern,
and alternatives for cleaning up the site. A final cleanup remedy is scheduled to be
selected in mid-1996.
Environmental Progress
The EPA has determined that the public and the environment are not at immediate risk while
investigations at the Atlas Tack Corp site continue and final cleanup alternatives are being
determined.

South Street in northwest Holbrook
Site Description
The Baird & McGuire facility is located on a 20-acre site in Holbrook and operated as a chemical
mixing and batching company from 1912 to 1983. Later activities included mixing, packaging,
storing, and distributing various products, including pesticides, disinfectants, soaps, floor waxes,
and solvents. Some of the raw materials used at the site were stored in a tank farm and piped to
the laboratory or mixing buildings. Other raw materials were stored in drums on site. Waste
disposal methods at the site included direct discharge into the soil, a nearby brook, wetlands, and
a former gravel pit. Hazardous wastes historically were disposed of in an on-site lagoon and
cesspool. Also included on site were two lagoons open to rain and large areas of buried wastes
such as cans, debris, and lab bottles and hundreds of bottles of chemicals. The lagoon area has
been capped with clay. The on-site buildings were in various states of disrepair and unsecured;
the EPA has since demolished all but one of the buildings and the tank farms. The tank farm area
has been temporarily capped. The site is completely fenced and has an operating groundwater
recirculation system to contain the groundwater plume. The site is 500 feet west of the Cochato
River, which was diverted into the Richardi Reservoir, a water system serving nearly 90,000
people in the Towns of Holbrook, Randolph, and Braintree. Currently, the Cochato River is not
being used as a supply source for the Richardi Reservoir. The South Street well field, part of the
municipal water supply for Holbrook, is located within 1,500 feet of the site and was shut down
in 1982.
Site Responsibility:
The site is being addressed through
Federal and State actions.

July 1995
-------
Threats and Contaminants
The groundwater is contaminated with pesticides and organic and inorganic chemicals.
Studies found significant levels of volatile organic compounds (VOCs), other organic
compounds, arsenic, and pesticides including DDT and chlordane in the Cochato
River sediments. The contamination is highest on site or within approximately 500
feet downgradient of the current site fence. Site soils were found to be contaminated
with VOCs, poly cyclic aromatic hydrocarbons (PAHs), other organic compounds,
pesticides, dioxin, and heavy metals such as lead and arsenic. Dioxin also has been
detected in area wetland soils. The last operating well in the South Street well field
was shut down in 1982 because of unacceptably high levels of organic contamination.
The area of the site is fenced; however, high levels of pesticides in site soils and
sporadic dioxin contamination pose an imminent threat to public health through
accidental ingestion of or direct contact with the contaminated soils or groundwater.
The groundwater plume continues to contaminate the Cochato River sediments;
however, no significant health risk was found, based on human contact with
contaminated sediments. Contaminated sediments were found to be acutely toxic to
aquatic life.
Cleanup Approach
The site is being addressed in five stages: immediate actions and four long-term remedial phases
addressing the cleanup of the groundwater, soil, and sediments and the provision of an alternate
water supply.
Response Action Status
Immediate Actions: The EPA completed a hydrological study in connection with
this site. The initial response action taken included the removal of 1,020 cubic yards
of hazardous waste, 1 ton of waste creosote, 25 gallons of waste coal tar, 155 pounds
of solid hazardous waste, 47 drums of flammable liquids and solids, and 2 drums of corrosives.
Additional activity included construction of a clay cap, installation of a groundwater
interception/recirculation system, installation of 5,700 feet of fencing, and extensive soil,
groundwater, surface water, and air sampling. The site was graded, capped, and seeded. The site
is secured by a fence to limit contact with contaminants.
Groundwater: The final cleanup remedy chosen to address groundwater
contamination involves pumping groundwater and treating it at an on-site treatment
plant. Treated groundwater will be discharged to the aquifer located on site. On- and
off-site groundwater will be monitored. A new 300,000 gallon-per-day groundwater pump and
discharge treatment plant was constructed and began operations in 1993. Approximately 40
million gallons of groundwater were treated during the plant's first year of operation. Operation
of the treatment plant is expected to last into the next decade.
July 1995 2 BAIRD & MCGUIRE
-------
Soil: In 1990, the EPA completed the engineering designs for the final cleanup
remedies. Approximately 142,000 cubic yards of contaminated soils are expected to
be excavated and removed. The remedy also calls for destruction of contaminants in
the soil by incineration. Wetlands will be restored where contaminated soils are excavated. The
unnamed brook will be relocated. Air quality will be monitored during construction and
implementation of the incineration system. Construction of the incinerator was completed in 1994
and trial burn began in early 1995. Incineration will last approximately two years.
Sediments: The groundwater discharge is believed to be partially responsible for
contamination of Cochato River sediments and adjoining wetlands. Field investigations
in 1987 and 1988 determined that contaminated groundwater and surface runoff from
the site continue to be the principal sources of contamination of the wetlands adjacent to the site.
The investigations defined the contaminants of concern and recommended alternatives for final
surface water and sediment cleanup. The investigations also determined that site contaminants
were being effectively trapped in river sediments and were not migrating down-river. In late
1989, a remedy was selected that entails excavating and incinerating approximately 1,500 cubic
yards of sediments on site. Design of cleanup actions was completed in 1991. Construction
activities began in 1994 and are scheduled to be completed in 1995.
Water Supply: In 1990, the EPA selected a final cleanup remedy that will
reactivate the Donna Road Aquifer, thereby replacing the loss caused by
contamination. Design of this remedy began in 1991 and was completed in late 1994.
Construction of the well-head treatment system is scheduled to begin in 1995.
Site Facts: Between 1954 and 1977, the company was fined at least 35 times by various State
and Federal agencies for numerous violations. A citizen complaint of an oily substance on the
Cochato River initiated a site inspection, which reported surface water, groundwater, and
wetlands contamination. In 1983, the City of Holbrook revoked Baird & McGuire's permit to
store chemicals and ordered it to dismantle the existing storage facilities. The EPA issued Notice
Letters to parties potentially responsible for site contamination. A cost recovery case against the
four potentially responsible parties was filed in 1983. The case was settled on an "ability-to-pay"
basis in 1987. A final Consent Decree was issued by the EPA and was signed by the potentially
responsible parties.
Environmental Progress
The initial cleanup, including the construction of a fence, and continuing actions described above
have greatly reduced the potential of exposure to contamination and continue to reduce
contamination levels at the Baird & McGuire site, making the area safer while it awaits final
cleanup activities. Millions of gallons of groundwater have been treated during the first year of
groundwater treatment plant operation.

Walpole
Other Names:
outh Street Site
after Realty Trust
The Blackburn and Union Privileges site, approximately 30 acres in size, is located in a primarily
residential area. Once known as The Blackburn Privilege and The Union Factory Privilege, these
two areas were originally part of 10 distinct water privileges established along the Neponset
River in the 17th century. Snuff, iron, nails, cotton, and wool were produced at the Union
Privilege site; a tannery also was located in this area. Power was generated by a dam on the
Blackburn Privilege for the production of machinery, cotton, yarn, batting, and lamp wicking.
Since the 17th century, industrial and commercial facilities have been active on 6 of 24 lots in
this area, with the remainder being used as residential and commercial properties. Industrial and
commercial processes conducted during the 17th and 18th centuries involved various hazardous
substances, including chromium, arsenic, and mercury. Beginning hi 1915, Standard Woven
Fabric Co. manufactured asbestos brake linings that involved the crushing of raw asbestos. In
1920, the company changed its name to Multibestos. A pile of raw asbestos still remains on site.
In 1937, the plant was closed and the properties were sold to Kendall Co., which used the site
for various cotton and fabric production processes. The wastewater resulting from these
operations was brought within sewer permit requirements and disposed of in two lagoons. It was
then discharged to a sanitary sewer after cotton fibers had settled out. Kendall stopped using the
first lagoon as a disposal area in 1982; the second lagoon received non-contact cooling waste
until 1985. The current owners of these properties are Shaffer Realty Nominee Trust and BIM
Investment Trust. Municipal wells located within 4 miles of the site draw water from the School
Meadow Brook/Mine Brook aquifer and supply drinking water to approximately 19,500 people of
the Town of Walpole. The nearest well is located within 1 mile of the site. The site lies within
the boundaries of the Neponset River drainage basin which bounds the southern portion of the
site.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.

Threats and Contaminants
On-site soils, sediments, and groundwater are contaminated with inorganic chemicals,
including asbestos, lead, arsenic, and nickel, volatile organic compounds (VOCs), and
non-volatile organic compounds. Ingesting or coming into direct contact with
contaminated soils, sediments, or groundwater poses a health risk.
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: In 1988, Shaffer Realty Nominee Trust and BIM Investment
Trust removed buried tanks and disposed of them off site. An investigation into the
nature and extent of asbestos contamination in the soil was also conducted. As a
result of an Administrative Order, an asbestos pile and asbestos-contaminated soils on site have
been contained. In addition, a 30 inch soil cover has been installed and a 400 foot long
aluminum plate arch culvert was built in 1993 to isolate a portion of the Neponset River running
through the area of contamination.
Entire Site: An investigation into the nature and extent of contamination is scheduled
to begin in 1996. Once the investigation is completed, proposed cleanup alternatives
will be recommended.
Site Facts: The EPA issued an Unilateral Administrative Order to Shaffer Realty Nominee
Trust and BIM Investment Trust on December 15, 1988, that required the potentially responsible
parties to perform the immediate actions described above and conduct an investigation to
determine the extent of asbestos contamination in soils. A second Unilateral Administrative
Order was issued to Shaffer Realty Trust and W.R. Grace in 1992, that required additional
actions to eliminate the actual or threatened release of asbestos into the air or water.
Environmental Progress
The removal of site contaminants in 1988 and 1993 has reduced the potential safety and health
risks to the nearby population while investigations are underway and activities are being planned
for final cleanup of the Blackburn and Union Privileges site.

Superfund Site
Site Description
The Cannon Engineering Corporation (CEC) site is situated on 6 acres between Route 24 and
First Street in Bridgewater. In 1974, Cannon developed the site to transport, store, and incinerate
hazardous wastes, but the facility currently is inactive. On-site structures included 21 storage
tanks, three buildings, an office/warehouse, and an incinerator. The operation was licensed in
1979 to store motor oils, oils and emulsions, solvents, lacquers, organic and inorganic chemicals,
plating waste, clay and filter media containing chemicals, plating sludge solids, and pesticides.
The facility had a license to operate from 1974 until 1980, when alleged waste mishandling and
reporting violations prompted the Massachusetts Executive Office of Environmental Affairs to
revoke it. The facility was placed in receivership when its owners were found to be guilty of
illegal storage and disposal. Operations ceased in 1980, leaving behind approximately 700 drums
and 155,000 gallons of liquid waste and sludge in bulk storage. The on-site soils, sediments,
buildings, groundwater, and surface waters are contaminated with volatile organic compounds
(VOCs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), pesticides,
and metals to varying degrees. The Cannon site is associated with three other NPL sites:
Tinkham Garage, Sylvester, and Plymouth Harbor. The Tinkham Garage and Sylvester sites are
located in New Hampshire. Approximately 1,000 people live within 1 mile of the Cannon
Engineering Corporation site in this residential and light industrial area. The nearest residence is
1/8 mile from the site. There are 13 homes within a 1-mile radius that depend on well water. The
closest municipal well is in Raynham, 1 mile from the site. Bridgewater's municipal wells are
located 3 miles east of the site.
Site Responsibility:
The site is being addressed through
Federal, State, and potentially
responsible parties' actions.

Threats and Contaminants
The on-site air contained trace amounts of VOCs, including benzene and methylene
chloride. Groundwater was also found to contain VOCs including toluene, as well as
heavy metals. Soil and sediments contained PAHs, PCBs, dioxin, and pesticides in
addition to VOCs and heavy metals. The surface water was polluted with heavy metals
including high levels of iron, selenium, lead, manganese, and silver. Direct contact
with and accidental ingestion of contaminated material posed a potential public health
threat. Inhaling VOCs and contaminated fugitive dust were potential health threats.
The site is fully fenced to reduce the potential for contact with contaminants. Sensitive
areas that could have been subject to contamination associated with the site include
wetland areas to the south and Lake Nippenicket to the west of the site.
Cleanup Approach
Response Action Status
Initial Actions: In 1982, the State removed 155,000 gallons of sludge and liquid
wastes and approximately 700 drums and incinerated the materials off site. In 1988,
the EPA and the parties potentially responsible for site contamination provided for
the removal and disposal of numerous hazardous materials abandoned at the site. A fence
surrounding the site was erected in 1989.
Entire Site: The final remedy for the site was selected in 1988 and entails two
cleanup phases, source control and restricting the migration of contaminants. Source
control elements included: fencing the area to restrict unauthorized access to
contaminated soils; treating certain contaminated soil on site by heating it to remove contaminants
and burning PCB-contaminated soils off site; installing a groundwater monitoring system;
decontaminating and removing buildings and associated structures; sampling and treating other
soils as necessary; and restorating wetlands disturbed during site cleanup. Key features of the
migration control remedy included restricting the use of groundwater at the site and installing
additional groundwater monitoring wells to keep apprised of the movement of contaminants. In
1990, under EPA and state oversight, cleanup activities were undertaken by the parties potentially
responsible for site contamination. Four hundred tons of PCB-contaminated soil were incinerated
off site, 11,330 tons of soils containing VOCs were treated on site, 1,200 tons of steel and 1,300
tons of concrete were shipped for recycling, 360 cubic yards of hazardous debris were sent to a
federally approved disposal facility, and 480 cubic yards of non-hazardous debris were shipped to
a demolition materials landfill. Cleanup activities were completed in 1991. The testing of debris
from the demolished incinerator for dioxin and subsequent removal was completed in 1991. The
incinerator was shipped off site to an EPA-regulated disposal facility. Once contaminated soils
were removed, the groundwater began to cleanse itself naturally. Long-term groundwater
monitoring began in 1991 and continued quarterly until 1993, at which time an evaluation of the
wells was performed. A five year review is expected to be conducted in 1995. Long-term
monitoring of the site will continue until cleanup goals have been met.

conduct engineering designs and cleanup actions at the site.
Environmental Progress
Construction of all cleanup remedies has been completed. Cleanup activities have resulted in the
removal of contaminated materials from the site, thereby reducing the risk of exposure to
hazardous substances at the Cannon Engineering Corp. site. Cleanup activities have also reduced
movement of contaminants off site. Long-term monitoring of the groundwater will continue until
cleanup goals have been met.

Site Description
From the late 1950s until 1967, the Charles-George Reclamation Trust Landfill, located 1 mile
southwest of Tyngsborough and 4 miles south of Nashua, New Hampshire was a small municipal
dump. A new owner expanded it to its present size of approximately 55 acres and accepted both
household and industrial wastes from 1967 to 1976. The facility had a license to accept hazardous
waste from 1973 to 1976 and primarily accepted drummed and bulk chemicals containing volatile
organic compounds (VOCs) and toxic metal sludges. Records show that over 1,000 pounds of
mercury were disposed of and approximately 2,500 cubic yards of chemical wastes were
landfilled. The State ordered closure of the site in 1983. That same year, the EPA listed the site
on the NPL and the owner filed for bankruptcy. Samples from wells serving nearby Cannongate
Condominiums and some nearby private homes revealed VOCs and heavy metals in the
groundwater. Approximately 500 people live within a mile of the site in this residential/rural
area; 2,100 people live within 3 miles of the site. The nearest residents are 100 yards away. The
site is bordered by Flint Pond Marsh and Flint Pond to the east, Dunstable Brook to the west,
and a condominium complex to the southeast. Seasonal livestock grazing occurs in the area.

Threats and Contaminants
The air on the site is contaminated with VOCs including benzene and vinyl chloride.
Benzene, tetrahydrofuran, arsenic, and 2-butanone, among others, have been detected
in the groundwater. Domestic wells contained benzene. Sediments have been shown to
contain low levels of benzo(a)pyrene. People face a potential health threat by ingesting
contaminated groundwater or inhaling landfill gas on the site. Flint Pond Marsh, Flint
Pond, and the Dunstable Brook, nearby wetlands, were threatened by contamination
migrating from the site.
July 1995
-------
Cleanup Approach
The site is being addressed in five stages: initial actions and four long-term remedial phases
focusing on providing a permanent water supply, capping the site, controlling the migration of
contaminants, and treating leachate in the groundwater.
Response Action Status
Initial Actions: In response to the discovery of contaminated well water in the
adjacent condominium complex in 1983, the EPA installed an insulated, above-
ground pipeline to supply residents with an alternate water supply. In 1983 and 1984,
the EPA installed a security fence and 12 gas vents, and the site was regraded to cover exposed
refuse.
Permanent Water Supply. In 1983, the EPA selected a final cleanup remedy that
would provide a permanent water supply to affected residents. With EPA funds, the
U.S. Army Corps of Engineers installed 4 miles of ductile iron water pipe,
constructed a pump station and water storage tank, and arranged for chlorination services. The
water line extension was completed in 1988.
Capping: In 1985, the EPA completed a study on capping the landfill and selected
the following remedies: installation of a full synthetic membrane cover and a surface
water diversion and collection system, which keeps rainwater from spreading
contamination; construction of a gas collection system venting to the atmosphere; and creation of
a leachate collection system around the entire site. Periodic mowing, landscaping, and
inspection/maintenance services will also be provided. The Corps of Engineers completed
construction of the full synthetic landfill cap in 1990.
Migration of Contaminants: In 1988, the EPA selected a final cleanup remedy to
restrict the movement of contaminants off site. Features of the remedy include:
pumping contaminated shallow groundwater and treating it biologically, along with the
leachate collected from the landfill cap system; collecting and incinerating gas vented from the
landfill; excavating and solidifying 500 cubic yards of contaminated sediments from Dunstable
Brook and placing them under the landfill cap; and monitoring groundwater. The U.S. Army
Corps of Engineers completed the design of the remedy in 1990 and awarded a construction
contract in early 1992. Construction of a gas treatment flare and one of two groundwater
extraction remedies was completed in 1995. Additional design work is being performed to
upgrade the landfill gas flare. Additional design work is being performed for the second
groundwater extraction system on the eastern side of the site. A four-well extraction system was
installed in late 1993 and was tied into one of two new leachate and groundwater pump stations.
This second system is scheduled to go on line in 1995. Site cleanup is expected to be completed
in 1996.

-------
Leachate: Leachate is currently pumped to a 3 1/2 million gallon lagoon and is
periodically treated. These interim leachate treatment rounds have been completed
and the fourth is expected to begin in 1995. Ultimately, leachate will be combined
with groundwater and will be treated jointly in a permanent treatment plant. Design activities for
the plant are underway and are scheduled to be completed in late 1997.
Site Facts: In May 1983, the EPA issued a Notice Letter to the Charles George Reclamation
Trust, requesting its cooperation in the cleanup. An Administrative Order was signed with the
potentially responsible parties to perform treatability studies and groundwater/leachate monitoring
with assistance from the EPA. Two out-of-court settlements have since been reached for
approximately $40 million for recovery of cleanup costs.
Environmental Progress
Providing a water supply system, installing a fence, capping the landfill area, controlling the
spread of leachate, burning off landfill gas and extracting contaminated groundwater have
provided a safe drinking water source and reduced the potential for exposure to hazardous
materials at the Charles-George Reclamation Trust Landfill site, making the site safer while
further cleanup activities are being planned.

Site Description
Fort Devens is 35 miles west of Boston. It covers 9,416 acres at the intersection of four towns:
Ayer and Shirley in Middlesex County, and Lancaster and Harvard in Worcester County.
Founded in 1917, the Fort trains active duty personnel to support various Army units. It also has
custody of Fort Devens-Sudbury Training Annex, 12 miles to the southwest, which was listed on
the NPL in 1990. Fort Devens can be divided into three areas: the 2,300-acre Central Post,
which is flanked by the 1,500-acre North Post and the 5,616-acre South Post. Studies have
revealed 76 potential hazardous waste sites on Fort land. Among them are the 15-acre explosive
ordnance disposal range (South Post), where explosives and unusable munitions have been
detonated or burned in open unlined pits since 1979 and where soil sampling has led to the
discovery of heavy metals, volatile organic compounds (VOCs), and explosives residues; the
84-acre sanitary landfill (Central Post), where household wastes, military refuse, asbestos,
construction debris, waste oil, and incinerator ash have been dumped since the 1930s; and a
firefighting training area (North Post), where the possibility for petroleum, oil, and lubricant
contamination exists, as evidenced by stained asphalt, concrete, and soil. The area is largely
rural/residential. Approximately 21,700 Fort employees and Ayer residents obtain drinking water
from wells located within 3 miles of the landfill; a Fort Devens well is 1,670 feet from the
landfill. An 8-mile section of the Nashua River lies within the Fort's boundaries. The 660-acre
Oxbow National Wildlife Refuge is in the east-central portion of Fort Devens on land the Army
deeded to the Department of the Interior in 1973. An 83-acre wetland is in the refuge northeast
of the ordnance range. In July 1991, Fort Devens was slated for closure under the Defense Base
Realignment and Closure Act. The closure of Fort Devens has accelerated the investigations and
cleanup to protect human health and the environment in a more timely fashion and facilitate
economic redevelopment by disposing of property to interested public and private parties. In
April 1993, the first parcel (18 acres) of the installation was leased to Boston and Maine
Railroad/Canadian Pacific Railroad for the operation of an Internodal Rail Transport Facility.

Monitoring wells near Shepley's Hill Landfill (Main Post) indicate inorganic
groundwater contamination from arsenic, cadmium, chromium, lead, iron, and
magnesium. Sediments in Plow Shop Pond, which is adjacent to the landfill, indicate
heavy inorganic contamination with the following metals: arsenic, cadmium,
chromium, lead, and mercury. Surface soils in several areas on the Main Post exhibit
heavy polycyclic aromatic hydrocarbon (PAH) and petroleum contamination. There is
also petroleum-related groundwater contamination from several leaking underground
storage tanks/fuel depots. A portion of the Nashua River and its surrounding wetlands
on Main Post are threatened by a demolition debris landfill. On the North Post, a
perchloroethylene (PCE) spill threatens the groundwater. On the South Post, there is
inorganic and explosives contamination in the surface soils and inorganic, VOC, and
explosives contamination in the groundwater. Sampling of the fish population has
indicated that mercury is present in fish tissue, thus posing a threat to the recreational
fishery. In addition, off-post sources are currently being investigated as contributors
to the sediment contamination.
Cleanup Approach
The site is being addressed in nine long-term remedial phases focussing on the cleanup of the
Shepley's Hill Landfill; Cold Spring Brook Landfill; EOD and Zulu Ranges; DRMO Yard and
the POL Storage Area; TDA Maintenance Yard; Hotel Range; South Post Impact Area
Groundwater; and other contaminated areas.
Response Action Status
Shepley's Hill Landfill: In 1991, the U.S. Army began an investigation to
determine the nature and extent of contamination. The groundwater and the adjacent
pond were found to be impacted. A final cleanup remedy is expected to be chosen in
Cold Spring Brook Landfill: In 1991, the U.S. Army began an investigation to
determine the nature and extent of contamination. The sediments in the pond adjacent
to the landfill were found to be effected. A final cleanup remedy is scheduled to be
chosen in the fall of 1995.
EOD and Zulu Ranges: In 1992, the U.S. Army began an investigation to
determine the nature and extent of contamination. Initial results have indicated
explosives and inorganic metals contamination in the soils. The investigation is
scheduled to be completed in 1996.
August 1995 2 FORT DEVENS
-------
DRMO Yard and the POL Storage Area: In 1991, the U.S. Army began an
investigation to determine the nature and extent of contamination. Results indicate
that soils are contaminated with inorganic chemicals such as arsenic, cadmium,
chromium, lead, and mercury; PCBs; VOCs; and petroleum products. The groundwater is
primarily contaminated with VOCs and petroleum products. In 1993, an interim removal action
was initiated at the DRMO Yard to remove leaking capacitors and PCB-contaminated scrap, and
to sample the adjacent offices. The capacitors and scrap were disposed of off site and the offices
were found to be unclean. Final cleanup remedies are scheduled to be selected in 1996.
TDA Maintenance Yard: In 1992, the U.S. Army began an investigation to
determine the nature and extent of contamination. Initial results indicted that heavy
contamination exists in the surface soils from carcinogenic PAHs and petroleum
products. A final cleanup remedy has been selected and design of the remedy is underway.
Hotel Range: In 1993, the U.S. Army began investigating this area to determine the
nature and extent of contamination. Initial results indicated that surface soils have
been impacted by explosives residues. A final cleanup remedy is scheduled to be
South Post Impact Area Groundwater: In 1993, the U.S. Army began
investigating the groundwater for effects associated with firing range and training
activities. To date, low levels of explosives have been found. At the conclusion of
the investigation, scheduled for 1996, a final cleanup remedy will be selected.
Other Contaminated Areas: In 1993, the U.S. Army began investigations of
several other areas located on North, Main, and South Posts. These investigations
will determine whether possible contamination warrants a detailed investigation or
removal or long-term cleanup of these areas.
Site Facts: Until the Base Realignment And Closure (BRAC) listing in 1991, Fort Devens was
participating in the Installation Restoration Program (IRP), a specially funded program
established in 1978 by the Department of Defense (DOD) to identify, investigate, and control the
migration of hazardous contaminants at military and other DOD facilities. Since 1991, Fort
Devens has been operating under the BRAC cleanup plan, which is the separately funded
counterpart to the IRP for installations undergoing realignment and closure. The Army and EPA
signed a Federal Facilities Agreement (FFA) in May of 1991. The FFA outlines the legal
framework for the cleanup.
Environmental Progress
To date, four removal actions have been completed that have focused on the cleanup of VOC-
and petroleum-contaminated soils. One removal action is ongoing that is addressing PCE
contamination in the soil and groundwater. Several more soil removals focusing on pesticides,
VOCs, inorganics, and petroleum contaminants are scheduled.

Site Description
The 4-square-mile (2,750-acre) Fort Devens-Sudbury Training Annex is a U.S. Army military
installation occupying portions of the Towns of Sudbury, Maynard, Hudson, and Stow. Hudson
Road divides the site into two sections. Established in 1942, the Annex has served as an
ammunition depot, an ordnance test station, and a troop training and laboratory disposal center. It
is now under the custody of Fort Devens, located 12 miles northeast of the site. Fort Devens is
also listed on the NPL. In an Installation Assessment Study conducted in 1980, the Army
identified 11 potentially contaminated areas on the site that contained explosive residues, chemical
laboratory wastes, oil lubricants, and other toxic materials. In 1985, 100 to 200 gallons of oil
containing polychlorinated biphenyls (PCBs) spilled from an out-of-service transformer in a
remote abandoned area of the Annex. Four other electrical transformer units in a remote section
of the Annex were found with bullet holes and dents that permitted PCB-contaming fluids to
escape. In 1986, monitoring wells downgradient from Waste Areas A7 and A9 were reported to
be contaminated with the volatile organic compounds (VOCs) trichloroethane and benzene. Area
A7 is a 20-acre gravel pit that was used from the 1940s to the 1980s as a laboratory dump and an
all-purpose dump. Area A9 is a 7-acre parcel used by the Commonwealth of Massachusetts since
the 1950s for fire training. The two areas are separated by an unnamed tributary of the Assabet
River. White Pond, which provides water to 12,000 residents of Maynard, is located
approximately 3 miles downstream of Waste Area A5, a 70-square-foot pit where laboratory
solvents were buried from 1973 to 1979. Approximately 35,700 people obtain drinking water
from public and private wells located within 3 miles of the waste areas; however, no private or
municipal wells are contaminated. Located along the northern boundary of the site, Puffer Pond
is being considered for recreational development. A private well lies 1,600 feet from one of the
waste areas. The area surrounding the Annex is mainly agricultural, with interspersed residential
areas. Aside from Army structures and clearings, the majority of the Annex is undeveloped with
a patchwork of forest, marsh, grassland and open water. Topographically, the Annex is mostly
lowlands, with some hills and surface water. A freshwater wetland is located within 600 feet of
Puffer Pond.

VOCs, xylene, pesticides, and inorganics have been detected in groundwater. Soils at
the Annex are contaminated with PCBs. People trespassing in certain portions of the
Annex are at risk from direct contact with contaminated soil. The freshwater wetland
is potentially at risk from contaminant migration. No private or municipal water
sources are contaminated.
Cleanup Approach
The site is being addressed in five stages: initial actions and four long-term remedial phases
focusing on cleanup of the groundwater (Waste Areas A7 and A9), the PCB spill area (Waste
Area A4), and additional contaminated areas.
Response Action Status
Initial Actions: The Army responded to the 1985 PCB spill by removing 300
gallons of Aroclor and approximately 75 tons of PCB-contaminated soil to an
EPA-approved facility. Workers discovered and removed four transformers and the
contaminated soil surrounding them. An additional 86 tons of contaminated soil was removed
from September through November 1985 at the Former Fire Training Area. The Army removed
1,110 cubic yards of contaminated soil from September 1987 through July 1988. To prevent
trespassers from physical harm and from coming into contact with contaminated areas, the Army
fenced off several sub-sites and buildings. The Army also completed removal of underground
storage tanks at the Annex.
Old Gravel Pit Landfill (Waste Area A7): A7 is a 10-acre site and was reportedly
used from the 1940s to the early 1980s for the disposal of laboratory chemicals from
the Natick Laboratory and miscellaneous solid waste. In 1991, the Army began an
investigation into the nature and extent of the landfill contents and the groundwater contamination
in Waste Area A7. Cleanup remedies are expected to be selected in 1995.
Former Fire Training and Flame Retardant Clothing Testing Area (Waste
Area A9): In 1991, the Army began an investigation into the nature and extent of
groundwater contamination in Waste Area A9. Final cleanup remedies are expected to
be selected in 1995.

Waste Dump (Waste Area A4): In 1991, the Army began an investigation into
the nature and extent of groundwater and soil contamination in Waste Area A4. Final
cleanup remedies are expected to be selected in 1995.
Additional Contaminated Areas: In 1993, the Army began an investigation into
the nature and extent of contamination at 65 additional contaminated areas of the site.
In-depth investigations will be performed at several areas of the site to determine if
further evaluations of remedies are necessary. Final cleanup remedies for these areas are
expected to be selected in 1996 and 1997.
Site Facts: A two-party Interagency Agreement between the EPA and the Army was signed on
May 13, 1991 outlining the legal framework for the site cleanup. The Sudbury Training Annex is
participating in the Installation Restoration Program, a specially funded program established by
the Department of Defense (DOD) in 1978 to identify, investigate, and control the migration of
hazardous contaminants at military and other DOD facilities. An EPA Technical Assistance Grant
was awarded to a local community group called Four Town FOCUS (Families Organized to
Clean Up Sites) in October 1991.
Environmental Progress
Initial activities have removed sources of contamination, reducing the potential for migration of
or exposure to hazardous materials at the Fort Devens-Sudbury Training Annex site. The EPA
has assessed the actions taken by the Army and determined that there are no immediate threats to
public health or the environment while final cleanup remedies are being planned.

Site Description
EPA REGION 1
Essex County
Groveland
The Groveland Wells site includes the watershed and aquifer supplying two contaminated
municipal water wells, as well as three properties known to be polluting groundwater and soil in
the area. The entire site area covers 850 acres. Groveland's production wells #1 and #2 were the
sole source of drinking water for the town. Both were shut down in 1979, when the State
detected trichloroethylene (TCE) contamination. The Town instituted emergency conservation
measures and temporarily obtained water hookups from neighboring communities. Groveland
developed well #3 along the Merrimack River in the early 1980s, but the water supply still falls
short of the town's needs and growth trends. The EPA is currently trying to initiate cleanup of
hazardous waste materials from the highly contaminated Valley Manufacturing Co. site, where
metals and plastic parts have been made since 1963. Operators used subsurface disposal systems
and underground tanks that dispersed liquids into buried leachfields. They routinely dumped
hazardous materials on the ground. From 1964 until 1972, as much as 20 gallons per month of
these materials were released. Chemicals released included cutting oils, volatile organic
compounds (VOCs), and acid bath wastes. An estimated 5,000 people live within 3 miles of the
site in this residential area. The EPA has built a groundwater treatment facility plant at well #1,
which has continuously provided a treated public water supply to the Town since 1989.
Site Responsibility:
This site is being addressed by Federal,
local, and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
The groundwater is contaminated with VOCs. Soil is contaminated with
trichloroethelene (TCE). The greatest threat is posed by drinking water from
contaminated wells, a danger that has been reduced by treating the public water
supply. Highly contaminated soil found on the Valley Manufacturing Co. property
could pose a risk to the workers involved in site cleanup activities.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: immediate actions and two long-term remedial phases
focusing on groundwater migration and source control.
Response Action Status
Immediate Actions: The EPA installed a groundwater treatment facility for
Groveland's municipal well station #1. In 1985, Valley Manufacturing Co., under a
State Order, installed a groundwater treatment system just north of the Old Mill
Pond. The treatment system intercepts and treats a defined area of groundwater contamination.
The EPA has been treating water from municipal supply well #1 with carbon adsorption to
remove VOCs since 1989. The treatment plant operated as a public water supply from August
through November 1987 and again from the spring through the fall of 1988. It went on line again
in early 1989 and is expected to operate on a continual basis throughout the life of the facility.
Groundwater Migration: The EPA began its initial study of site contamination and
cleanup options in 1983. The initial study was completed in 1985. In 1990, the EPA
began conducting a supplemental management of migration study to evaluate the
movement of groundwater contaminants, and to determine what further cleanup activities were
needed. This supplemental study was used to develop a permanent remedy to address
contamination throughout the Johnson Creek aquifer. In 1991, this investigation was completed
and the remedy for cleanup was selected. The remedy called for extraction and treatment of
contaminated groundwater. Organic contaminants in the groundwater will be treated by ultraviolet
light/oxidation. Design of the final cleanup remedies began in 1992, and is scheduled to be
completed in 1995.
Source Control: A supplemental study based on initial studies narrowed the focus
on contamination to one location, and remedies for the Valley area were selected.
They include in-place vacuum extraction of VOCs from 20,000 cubic yards of site
soils and capture of those contaminants by activated carbon treatment, pumping on-site
groundwater and treating it by air stripping, monitoring groundwater, and sealing or
disconnecting all lines to the acid bath finishing process disposal system. Incidental treatment of
inorganic compounds and other contaminants will be provided as necessary to operate the VOC
contaminant treatment system efficiently and meet federally-approved limits. Design of the
remedies was completed in 1993; however, the potentially responsible parties have failed to
implement the approved design and the EPA has taken over the project. Re-design of the cleanup
remedy began in 1993 and is expected to be completed in 1995. The EPA's redesign of the
project included tests to evaluate optimum groundwater recovery rates. The results of these tests
indicated that there was insufficient amount of groundwater to justify building a groundwater
treatment facility at the site. However, the EPA plans to extract as much contaminated
groundwater as possible from the site, and transport this contaminated groundwater to the
ultraviolet light/oxidation treatment facility that is presently under design for groundwater
migration.
July 1995 2 GROVELAND WELLS
-------
Site Facts: The Town of Groveland sued the potentially responsible parties and settled with one
of them to undertake a study of the nature and extent of contamination. The nearby Haverhill site
has been determined to be contributing to the groundwater contamination and has been separately
added to the NPL. In May 1992, a Unilateral Administrative Order was issued that required the
potentially responsible parties to initiate technical designs for cleanup of the groundwater
migration and to initiate the actual cleanup activities. Although the design was completed, the
potentially responsible parties have not complied with the order to perform the actual cleanup
activities and the EPA is in the process of designing the remedy.
Environmental Progress
Initial construction of water treatment facilities has provided a safe drinking water source, and the
various cleanup actions taking place at the Groveland Wells site have reduced the possibility of
exposure to hazardous materials and continue to reduce contamination in groundwater. Final
cleanup remedies to address groundwater migration have been selected and are being designed.
Cleanup activities are expected to begin in 1995.

Site Description
The Hanscom Field/Hanscom Air Force Base site covers approximately 1,120 acres in a light
industrial area of eastern Massachusetts. The site spans the Towns of Bedford, Concord,
Lexington, and Lincoln. The Naval Weapons Industrial Reserve Plant site, also included on the
NPL, is located due south of the Hanscom Field/Hanscom Air Force Base site. In 1942, the
military began using a public airfield at the site that had been built the previous year. In 1952,
the Commonwealth of Massachusetts transferred 396 acres and leased 641 acres of land to the
Air Force. The Commonwealth retained the remaining 83 acres for its own use. Military flying
activities ceased in 1973, and the Commonwealth regained control of the leased acreage. The
airfield and surrounding land were given to the Massachusetts Port Authority (Massport), which
began operating a civilian airport, called the L.G. Hanscom Field. Hanscom Field remains active
today. The Air Force continues to occupy the 396 transferred acres and operates the Electronic
Systems Division of the Air Force Systems Command as Hanscom Air Force Base. Throughout
the 32 years of Air Force occupation, numerous hazardous substances were used, generated, and
disposed of on the airbase and what is now the Massport property. These substances included
chlorinated solvents; gasoline and jet fuel; aromatic solvents; tetraethyl lead, a gasoline additive;
and polychlorinated biphenyls (PCBs). In 1980, two wells belonging to the Veterans
Administration Hospital in Bedford were closed down after volatile organic compounds (VOCs)
were detected in the well water supply. In 1984, VOCs were discovered in three of the Town of
Bedford's wells. The wells were subsequently shut down. Bedford draws its drinking water
from groundwater beneath the base, and therefore conducted an investigation of the base to
determine if it was the source of the contaminated groundwater. The investigation, conducted in
1991, revealed that groundwater and surface water were contaminated with VOCs, and were the
likely source of the contamination of the Town's water supply. A total of 22 possible sources of
contamination were identified, including two former fire training areas, a paint waste disposal
area, a jet fuel residue/tank sludge area, two landfills, a former industrial wastewater treatment
system, a former filter bed area, an elemental mercury spill, and a PCB transformer storage area,
and various underground storage tank spill areas.

Threats and Contaminants
Groundwater and soils are contaminated with VOCs, solvents, gasoline and jet fuel,
PCBs, and tetraethyl lead. People who come into direct contact with or ingest
contaminated ground water or soil may be at risk.
Cleanup Approach
This 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: Drums of waste from the Paint Waste Disposal Area and the Jet
Fuel Residue/Tank Sludge Area were removed. Underground storage tanks and
contaminated soils have also been removed and placed in a secured landfill. A
groundwater treatment system has been built to remove VOC and petroleum contamination from
ground water beneath the base.
Entire Site: In 1991, the Town of Bedford began an investigation into the nature
and extent of groundwater and soil contamination. The EPA is currently reviewing
the results of the investigation to determine the best approach for cleaning up the site.
Environmental Progress
The operation of the groundwater treatment system and the removal of drums of waste and
contaminated soils have reduced the immediate threats to the public and the environment at the
Hanscom Field/Hanscom Air Force Base site while investigations continue and further cleanup
actions are being planned.

the Merrimack River. Trimount Bituminous Products operated the site as an industrial landfill
beginning in the late 1930s, and started to accept municipal wastes in the 1960s. Two of the
landfill's three tracts were used for the disposal of municipal and commercial refuse, while the
third received liquid wastes and sludges. Wastes included steel drums, tires, and flammables,
including lacquers, paints, oils, and glues. These materials were either dumped on the surface of
the site or deposited into shallow pits. Sludges and liquids were dumped near the river, which
borders the site on the north. Resulting land erosion carried liquid wastes into the river.
Monitoring wells located a short distance upgradient from the river showed signs of
contamination. Until 1975, the landfill was operated in an unsanitary manner with little
compaction of refuse. The facility closed in 1981. Since 1981, the landfill has accepted sludges
generated by the Haverhill Wastewater Treatment Plant. The sludge is mixed with sand or loam
and then spread over the surface of the landfill. Numerous reports have cited lax security on the
property; dirt bikers have been observed riding on the site. The area is residential. The two
nearby towns, Haverhill and Groveland, have a combined population of approximately 51,400.

Threats and Contaminants
Z1AJ
The soil is contaminated with benzoanthracene and dibenzofuran, and volatile organic
compounds (VOCs). Chromium and arsenic have been found in liquids on site. A
nearby creek is contaminated with VOCs and manganese. Drums found on site
contained material contaminated with VOCs including toluene and xylene. The
groundwater is contaminated with VOCs and heavy metals including arsenic, lead,
mercury, manganese, and chromium. People who accidentally ingest contaminated
groundwater or come into contact with contaminated surface waters may be at risk.

-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup alternatives for the entire site.
Response Action Status
Initial Actions: In 1990, the EPA discovered two drums of unknown material on
the site. Tests revealed the contents of the drums to be contaminated with VOCs. The
contaminated drums were stabilized and removed from the site by the site owner.
Entire Site: An investigation into the nature and extent of the site contamination is
scheduled to begin in 1996. The results of the study, scheduled for completion in
1999, will identify appropriate cleanup strategies.
Environmental Progress
After removing contaminated drums, the EPA has determined that the public is not at immediate
risk while the Haverhill site awaits further investigations.

-22* .
The 23-acre Hocomonco Pond site included a recreational pond that was closed by the State in
1980. From 1928 to 1946, the site was used as a wood-treating operation. The business consisted
of saturating wood products with creosote for preservation. During the operations, wastewater
was discharged into a pit lagoon. The lagoon was excavated on the property to store spillage and
waste from the wood-treating operation. As this lagoon became filled with waste creosotes,
sludges, and water, its contents were pumped into a low depression, also known as Kettle Pond.
The wood-treatment facility operated until the mid-1940s, when it was converted into an asphalt
mining plant. Discarded aggregate and asphalt are common throughout the site. The last use of
the site was as a cement plant where dry cement was distributed in bulk. The surface water and
groundwater have shown creosote contamination. Approximately 2,500 people depend on
ground water as a drinking water supply, and 14,000 people use the surface water for other
purposes. All live within 3 miles of the site. The nearest residences lie 2,000 feet from the site.

The site is being addressed through
Federal and potentially responsible

NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
The groundwater, soil, and sediments from the pond and its shore are contaminated
with creosotes, carcinogenic compounds, and heavy metals including arsenic and
chromium. People who come into direct contact with or accidentally ingest
contaminated soil, sediment, and groundwater may be at risk.
July 1995
-------
Cleanup Approach
The site is being addressed in two long-term remedial phases focusing on interim source control
and landfill and groundwater treatment.
Response Action Status
Interim Source Control: In 1989, the EPA selected the following cleanup
remedies: site grading, capping, and relocation of the storm drain pipe currently
located adjacent to the east side of the former lagoon. The parties potentially
responsible for site contamination completed relocation of the storm drain pipe in 1990. The site
has been graded and capped.
Landfill and Groundwater Treatment: In 1985, final cleanup remedies were
selected for the Kettle Pond area. Since that time, a significant amount of
contamination was discovered in deeper soil at the Kettle Pond area which caused the
original remedy to be reevaluated. The selected remedy now consists of excavating the top 4 to 5
feet of contaminated sediments and soils within the Kettle Pond area followed by in-place
bioremediation of the remaining contaminated soils. Hocomonco Pond and a discharge stream
also will be dredged and contaminated sediments will be disposed of in an on-site lined landfill.
The removal and on-site disposal of contaminated materials at isolated areas of contamination, air
and water quality monitoring, and post-closure activities are consistent with federal regulations.
The cleanup design was completed in 1993. The parties potentially responsible for site
contamination began construction of the remedies in the fall of 1993, beginning with the
groundwater treatment plant. The groundwater treatment plant, completed in 1994, will operate
until the groundwater meets required safe cleanup levels. Construction of a landfill on the site for
the containment of contaminated soil and sediments and dredging of sediments in Hocomonco
Pond also were completed in 1994. Remaining cleanup activities include: dredging of sediments
from Hocomonco Brook; excavating soils in a former tank farm area; constructing liners to cover
the surface of the landfill and the surface of a former lagoon; and sealing/lining of a storm drain.
Remaining cleanup activities are scheduled for completion in the fall of 1995. In-place
bioremediation of the Kettle Pond soil area will begin in the fall of 1995 and will continue for
several years.
Site Facts: A Consent Decree was filed in the U.S. District Court in 1987, allowing the
potentially responsible parties to design and construct the selected remedy.
Environmental Progress
Site grading, capping, relocating a storm drain pipe, constructing a landfill, and dredging
sediments, have made the Hocomonco Pond site safe while further cleanup activities are ongoing.

Woburn Site
Industri-Plex 128 Site
Site Description
The Industri-Plex site is a 250-acre industrial park. From 1853 to 1931, the site was used for
manufacturing chemicals such as arsenic insecticides, acetic acid, and sulfuric acid for local
textile, leather, and paper manufacturing industries. Chemicals manufactured by other industries
at the site include phenol, benzene, and toluene. From 1934 to 1969, the site was used to
manufacture glue from raw animal hides and chrome-tanned hides. From 1969 until the present,
the site has been developed for industrial use. Excavation in the 1970s uncovered and mixed
industrial by-products and wastes accumulated over 130 years. Residues from animal hides used
in the manufacture of glue were buried in pits on the site property. Process wastewater was
settled on site and was discharged to the municipal sewer. Many of the pits, piles, and lagoons
are continuously leaching toxic metals into the environment. Many of the wastes in the soil were
relocated and mixed into piles near swampy areas on the property. The site currently consists of
streams and ponds, a warehouse and office buildings, and waste deposits buried on the site.
Animal hide residues are found on approximately 20 acres of the site in four different piles.
Portions of stockpiled wastes sloughed off, releasing hydrogen sulfide gases to the atmosphere
and toxic metals and soils to the pond and wetlands. Residences are located within 1,000 feet of
the site, and more than 34,000 people live within 3 miles of the site.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Threats and Contaminants
The groundwater is contaminated with volatile organic compounds (VOCs) including
benzene and toluene, and with arsenic. The soil is contaminated with heavy metals
including arsenic, chromium, and lead. Also, a pervasive "rotten egg" odor has been
caused by hydrogen sulfide gas generated by the decay of the buried animal hides
from glue manufacturing wastes. People who accidentally ingest or come into contact
with contaminants may be at risk. However, since the site is mostly vacant now, with
plans for industrial and commercial use, the potential exposure most likely is limited
to workers on the site during future construction. The contaminated groundwater has
the potential to migrate to two Woburn municipal drinking wells, which are currently
closed. Wetlands near the site are threatened by site runoff.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on site stabilization and cleanup of groundwater contamination.
Response Action Status
Initial Actions: In 1986, the EPA installed 10,000 feet of fence to restrict site
access in 1986. Extensive damage to the main areas of the fence occurred, and drums
were dumped illegally on the site. Areas of the fence requiring repairs were
identified by the EPA, and work to re-secure the site was completed in 1988. Warning signs also
were posted.
Site Stabilization: In 1986, the EPA selected a final cleanup remedy that is being
implemented by the parties potentially responsible for site contamination. To address
the problem of approximately 90 acres of contaminated soils and sludges, the site will
be graded, a permeable soil cap will be installed over certain areas, institutional controls will be
implemented, water quality will be monitored, and post-closure activities will be maintained,
consistent with hazardous waste regulations. To address groundwater contamination at the site, an
interim remedy was selected that includes the extraction and treatment of the groundwater to
remove VOCs. Ultimately, treated water will be discharged to the surface water and the aquifer.
This will help disperse remaining contaminants. Treatment will be followed by groundwater
monitoring. Remedies selected in connection with odors and air contamination at the East Hide
Pile include stabilization of the side slopes of the various piles, installation of a gas collection
layer, installation of a synthetic and impermeable membrane cap to prevent rainwater from
entering the piles and gases from escaping without treatment, treatment of gases with either
activated carbon or thermal oxidation (the final treatment selection will be decided after the
impermeable cover has been installed), implementation of an air quality monitoring program, and
routine maintenance. The potentially responsible parties began designing the cleanup remedies in
1989. Design of the site cap was finalized in 1992. Construction of the cap began in 1993 and is
expected to be completed in 1995. Design of the interim groundwater treatment system was
completed in the fall of 1992 and the system is undergoing construction. The treatment system
was operational for a short period in the summer of 1994, when the EPA discovered that design
modifications were necessary. Construction activities are expected to be completed in 1996.
Groundwater Contamination: In 1990, the EPA and the potentially responsible
parties began an investigation into the extent and nature of site-wide groundwater
contamination. The investigation is expected to be completed in 1998 after completion
of the site stabilization activities. The investigation will identify the level of metals and organics
in the contaminated plume and also will determine what additional remedies may be required to
cleanup site groundwater.
July 1995 2 INDUSTRI-PLEX
-------
Site Facts: In 1979, in response to illegal filling of wetlands, the EPA obtained a court order to
stop further development activities. The EPA and the State entered into a Consent Order with
Stauffer Chemical in 1982, whereby Stauffer was to conduct an investigation and recommend
cleanup action. In 1988, the EPA and the potentially responsible parties signed a Consent Decree
to implement the remedy for stabilizing the site and to reimburse the EPA for past and future
oversight costs.
Environmental Progress
Initial actions of fencing and posting warning signs around the site have restricted access to the
Industri-Plex site and made it safer while final cleanup activities continue. Upon completion of
the final cleanup remedies, the soil and groundwater contamination levels at the Industri-Plex site
will be reduced to meet established health and ecological standards.

Site Description
The Iron Horse Park site, a 533-acre industrial complex, includes manufacturing and railyard
maintenance facilities, open storage areas, landfills, and wastewater lagoons. A long history of
activities at the site, beginning in 1913, has resulted in the contamination of soil, groundwater,
and surface water. An asbestos landfill is located to the northwest and adjacent to the lagoons
area. Middlesex Canal runs along the length of the northern boundary. It is drained by Content
Brook, which runs through residential areas into the Shawseen River east of the site. Richardson
Pond lies north of the site and is also drained by the Content Brook. An unnamed brook, which
runs northerly through the site near wastewater lagoons, drains into a marshland near the asbestos
landfill. Approximately 61,000 people live within a 3-mile radius of the site. There are four day
care centers or nursery schools, two housing units for the elderly, and a walk-in clinic in the
area. A trailer park and condominium complex are located within a mile of the site.

NPL LISTING HISTORY
Proposed Date: 09/08/83
Final Date: 09/21/84
Threats and Contaminants
On-site groundwater and surface water are sporadically contaminated with organic and
inorganic chemicals, asbestos, and heavy metals including arsenic, cadmium, lead,
and selenium. The soil at the site is contaminated with polychlorinated biphenyls
(PCBs), petrochemicals, and the same heavy metals as those found in the
groundwater. The majority of surface water contamination is located in the vicinity of
the now-closed Shaffer Landfill. People may be at risk by coming into direct contact
with or accidentally ingesting contaminated water, soil, or sediments. Environmentally
sensitive marshland and wetlands are located near the site and could be subject to
contamination.
July 1995
-------
Cleanup Approach
The site is being addressed in four stages: initial actions and three long-term remedial phases
focusing on cleanup of the lagoon areas; Shaffer Landfill; and the groundwater, surface water,
sediments, and soil throughout the rest of the site.
Response Action Status
Initial Actions: In 1984, the EPA removed asbestos deposits from various areas on
the site and covered an asbestos landfill with gravel, stone, and topsoil. The EPA
then seeded and fenced the area. By covering the asbestos landfill, the EPA
eliminated the potential of inhaling fugitive asbestos dust particles.
Lagoon Areas: The remedy selected by the EPA to be performed by the site owners
involves excavation and on-site treatment of contaminated lagoon soil and sludge by
bioremediation, with the residue disposed of in the lagoon area. This action will be
followed by covering the area with clean soil and establishing a vegetative cover. The owner will
then decontaminate the lagoon system piping and pumps. Development of the design and
specifications for these remedies was completed in 1991 and site cleanup activities began shortly
thereafter. Construction is scheduled for completion in 1996.
Shaffer Landfill: In accordance with a State Consent Agreement, the Shaffer
Landfill has been closed. The site owners installed a two-layer cover over the
landfill, the bottom layer consisting of low-permeability clay material and the top
layer of soil capable of supporting vegetation. In addition, a gas collection and a gas vent/flare
system were installed to reduce odors from the landfill. In 1991, the EPA completed an
investigation of the Shaffer Landfill area that evaluated the current cover and considered other
capping options. Cleanup methods selected included reconstruction of the landfill cap and
collection and off-site treatment and disposal of leachate. The potentially responsible parties have
assumed responsibility for the development of the design and specifications, which are expected
to be complete in late 1995.
Groundwater, Surface Water, Sediments, and Soil: Extensive sampling was
conducted during 1993 to evaluate the levels, extent, potential sources, and possible
means of migration of contamination in these media. Additional investigations began
in 1994, and final cleanup technologies are expected to be selected in late 1996.
Site Facts: A Consent Agreement was reached in 1984 between the State and the site owners
for closure of the Shaffer Landfill. The agreement established a series of cleanup activities and a
schedule for their implementation at the landfill. In 1990, the potentially responsible parties
assumed responsibility for designing the cleanup approach for the lagoon areas under a Consent
Decree with the EPA. In 1993, potentially responsible parties assumed responsibility for
designing the remedy chosen by the EPA to address the Shaffer Landfill.
July 1995 2 IRON HORSE PARK
-------
Environmental Progress
The removal of asbestos materials and the construction of a fence surrounding the landfill have
reduced the potential for exposure at the Iron Horse Park site while further cleanup activities are
being planned. The installation of a cap also will control odors and eliminate the migration of
contaminants into the surface water and groundwater on and off site. Further planned activities
will reduce contamination levels at the site, making it safe to area residents and the environment.

Site Description
The Materials Technology Laboratory (USARMY) (MTL) site occupies a total of 47¥2 acres,
with 36!/2 acres located on the north bank of the Charles River, approximately 5 miles west of
Boston. The facility was established hi 1816 by President James Madison, and was originally
used for the storage, cleaning, repair, and issuance of small arms. During the mid-1800's, the
mission was expanded to include ammunition and pyrotechnics production; materials testing and
experimentation with paints, lubricants, and cartridges; and the manufacture of breech loading
steel guns and cartridges for field and siege guns. The mission, staff, and facilities continued to
expand until after World War II, at which time the facility encompassed 131 acres, including 53
buildings and structures, and employed 10,00 people. Arms manufacturing continued until an
operational phasedown was initiated in 1967. In 1968, GSA sold approximately 55 acres to the
Town of Watertown. This property was subsequently used for the construction of apartment
buildings, the Arsenal Mall, and a public park and playground. MTL currently employs
approximately 300 people and contains 15 major buildings and 15 associated structures. In 1960,
the Army's first material research nuclear reactor was completed at MTL. The reactor was used
actively in molecular and atomic structure research activities until 1970, when it was deactivated.
The research reactor was decommissioned under the jurisdiction of the Nuclear Regulatory
Commission in 1992 and the structure was demolished in 1994. At the time of the operational
phasedown, much of the MTL property was transferred to General Services Administration
(GSA). The current mission of MTL is materials testing, structural integrity testing, solid
mechanics, lightweight armor research and development, and manufacturing testing technology.
In 1987, the U.S. Army Toxic and Hazardous Material Agency (THAMA) initiated preliminary
site studies, the first stage of the facility's closure plan. In late 1988, Congress officially
recommended the closure of the facility. There is a private drhiking water well located 2l/2 miles
northwest of the property. The municipal drinking water within 4 miles of the site is supplied by
surface water sources located to the west of MTL and is unaffected by the site. The Charles
River is used for recreational boating, swimming, and fishing. The active portion of MTL is
completely fenced and public access is restricted. MTL is scheduled for closure by the fall of
1995.

number of the containers at the site and poses an additional risk.
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: Leaking underground storage tanks and drums containing mixed
waste have been removed from the site. The nuclear reactor and associated buildings
and structures were demolished in 1994.
Entire Site: The U.S. Army initiated site studies in 1991 and 1992. Once these
studies are complete, the EPA will recommend alternatives for cleanup of the site.
Environmental Progress
The removal of leaking underground storage tanks, the decommissioning of the nuclear reactor
and associated buildings and structures, and the removal of drums containing mixed waste have
reduced the risk posed to the public and the environment while site studies leading to the
selection of final cleanup remedies continue.

Site Description
The Natick Laboratory Army Research, Development, and Engineering Center (Natick
Laboratory) is a 74-acre facility located in Natick, Massachusetts. The Natick Laboratory
occupies a peninsula on the eastern shore of Lake Cochituate and is bordered on the north by a
residential area. The site was purchased by the Army in 1949 and primarily used as a forested
recreational area, but it also included a gravel pit in a section of the site known as the Building
T-25 Area. The Army built the Natick Laboratory in 1954 and has since used the area for
industrial, laboratory, and storage activities for research and development in the areas of food
science, aero-mechanical, clothing, material, and equipment engineering. During its operation,
the Army used a variety of substances including the volatile organic compounds (VOCs)
tetrachloroethene, trichloroethene, carbon disulfide, benzene, chloroform, and acetone; "standard
laboratory chemicals"; mineral spirits/turpentine; paints; inks; lubricants; gasoline; tetraethyl
lead, a gasoline additive; pesticides; and metal dusts. In 1989, personnel at the facility noticed a
sheen on the site runoff water generated during rainstorms. Construction workers also noticed a
benzene-like odor in soil near a boring that was drilled for the construction of a gymnasium on
site. The Army conducted soil gas surveys in the Building T-25 and Gymnasium Areas and
detected several types of VOCs. In addition, soil, groundwater, and surface water samples
revealed elevated levels of VOCs and a variety of heavy metals, such as barium, arsenic, copper,
chromium, lead, and zinc. Other potential sources of contamination have been identified near the
laboratory. Petroleum, organic compounds, and chlorinated solvents have been discovered in soil
and groundwater on a property previously used as a laundromat, which is located approximately
3,600 feet from the laboratory well field. Several other potential sources of groundwater
contamination, including automotive garages and other laundromats, have been identified. The
Evergreen and Springfield municipal well fields are located in the area and may be threatened by
the contaminated groundwater. About 37,000 people obtain their drinking water from wells
within 4 miles of the site.

Threats and Contaminants
Soil, groundwater, and surface water are contaminated with various VOCs,
naphthalene, and Freon 113 and a variety of heavy metals such as barium, arsenic,
copper, chromium, lead, and zinc. Contamination threatens several municipal well
fields. Contamination also may threaten Lake Cochituate, which borders the site on
the east. People who ingest or come into contact with contaminated soil, surface
water, or groundwater may be at risk.
Cleanup Approach
This site is being addressed in three long-term remedial phases focusing on the cleanup of the T-
25 Area, the Former Gym Site, and the remaining areas of the site.
Response Action Status
T-25 Area: The Army began an in-depth study of soil and groundwater
contamination at the T-25 Area in 1993. Further studies are expected in 1995 that will
determine cleanup strategies for containing contaminant migration. The Army is
currently monitoring the groundwater in the T-25 Area.
Former Gym Site: The Army is scheduled to begin an extensive investigation of
groundwater and soil contamination at the Former Gym Site in the fall of 1995. This
investigation will lead to the selection of cleanup remedies for the area.
Remaining Areas: The Army has identified several other areas of possible
contamination at the site. In 1996, detailed investigations are scheduled to be
performed at some of these areas to determine the full extent of contamination.
Environmental Progress
The EPA has determined that the Natick Laboratory Army Research, Development, and
Engineering Center site poses no immediate threat to human health or the environment while
studies leading to site cleanup are being planned and conducted.

Site Description
The Naval Weapons Industrial Reserve Plant (NWIRP) is a 46-acre facility that is part of a larger
industrial complex located immediately north of Hanscom Air Force Base, which is also on the
NPL. NWIRP and the Raytheon Missile Systems Division (RMSD), also located within the
industrial complex, are operated by Raytheon Co. Operations continue today at NWIRP, which
was established in 1952 when a missile and radar development laboratory was built. Then known
as the Naval Industrial Research Aircraft Plant (NIRAP), the laboratory's mission was to provide
facilities for research and development of radar, missile guidance systems, and related equipment.
Flight test facilities were added on the southern portion of the site in 1959. Between 1959 and
1977, the Navy obtained about 43 additional acres from the Air Force. Buildings constructed
during the past 25 years include large facility storage and government buildings near the northern
property boundary, an Antenna Range Building, air conditioning and incineration facilities, and
the Advanced Medium Range Air to Air Missile Development (AMRAD) Building. NWIRP
currently is used for advanced technology research in weapons systems development. These
activities include the design, fabrication, and testing of prototype equipment such as missile
guidance and control systems. There are two primary operating areas at NWIRP: the
Components Laboratory and the Flight Test Facility. Approximately 21 other buildings house
various support activities related to the work at these two centers. Throughout its operational
history, NWIRP has generated or stored wastes at numerous locations. Hazardous waste was
disposed of either through direct discharge to the septic system or through barrel storage and off-
site disposal. The septic system consisted of on-site leaching fields until municipal sewer lines
were constructed. Wastes generated at NWIRP include various volatile organic compounds
(VOCs), photographic fixer, waste oil and coolants, lacquer thinner, unspecified solvents and
thinners, Stoddard solvent, waste paint, and chromic, sulfuric, nitric, hydrochloric, and
phosphoric acids. The Hartwell Road Well Field, part of the municipal water supply for the
Town of Bedford, is located less than 1/2 mile from NWIRP. The three wells in this field were
closed in 1984 after VOC contamination was discovered. The Town of Bedford conducted an
investigation that determined that NWIRP was a likely source of the well field contamination.
Hanscom Air Base is also a potential contributor to the groundwater contamination in this area.
Approximately 11,000 people rely on drinking water wells within 4 miles of the site. The
Shawsheen River, 7 miles downstream of NWIRP, is a source of drinking water for
approximately 12,800 people. Nine residential areas and wetlands are located to the east and
northeast of the site. There are extensive wetlands and several species of rare plants and wildlife
along the Shawsheen River and the Elm Brook, both located downstream of NWIRP.

Threats and Contaminants
Final Date: 05/31/94
Hazardous wastes generated at NWIRP include VOCs, photographic fixer, waste oil
and coolants, lacquer thinner, unspecified solvents and thinners, Stoddard solvent,
waste paint, and chromic, sulfuric, nitric, hydrochloric and phosphoric acids. Iron
and VOC contamination including benzene, trichlorethene, and tetrachlorethene have
been detected in three water supply wells operated by the Town of Bedford; these
wells have since been closed. There are extensive wetlands and several species of
rare plants and wildlife along this river and the Elm Brook, which is also located
downstream from NWIRP. Ingesting or coming into contact with contaminated
ground water or wastes could be a health risk.
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: In 1986, the Navy initiated a study to determine potential contaminant
sources at NHIRP. The study focused on past hazardous substance storage, use and
disposal practices at the site. As a result, two disposal and spill sites were identified:
the Old Incinerator Ash Disposal Area and the Components Laboratory Fuel Tank Area. Potential
contaminants of concern were metals in soils and groundwater near the Ash Disposal Area, total
petroleum hydrocarbons (TPH) in soils and metals, and TPH in surface water near the
Laboratory Fuel Tank Area. The study concluded that neither of the two areas posed a threat to
human health or the environment, and that the contaminant migration from them was unlikely.
Additional investigations were conducted at NWIRP in 1989 and 1990. These investigations
provided further data on soil and groundwater contamination associated with past storage and
disposal practices at NWIRP. The investigation initially focused on the Ash Disposal Area and
the Laboratory Fuel Tank Area, but also identified additional locations where potential
contaminant sources might exist, including underground storage tanks (UST) for fuel and waste,
leach fields, dry wells, and waste storage areas. The investigations concluded that additional
studies are needed to completely characterize the nature and extent of contamination of the
NWIRP. More investigations began in late 1994 which are scheduled for completion in 1998.

Site Description
The 18,000-acre New Bedford site is an urban tidal estuary consisting of a harbor and bay that
are highly contaminated with polychlorinated biphenyls (PCBs) and heavy metals. Manufacturers
in the area used PCBs while producing electric capacitors from 1940 to 1978. Until the late
1970s, when the use of PCBs was banned by the EPA, factories discharged industrial process
wastes containing PCBs into the harbor. As a result, PCB contamination in the New Bedford
Harbor area is widespread. The harbor is contaminated for at least 6 miles, from the upper
Acushnet River into Buzzards Bay. Approximately 98,500 people are living within 3 miles of the
site. A 5-acre northern portion of the Acushnet River Estuary is contaminated with high levels of
PCBs and has been identified as the "hot spot" area of the site. Measurements taken at the site
indicate tidal action transports PCBs from the hot spot to the harbor and ultimately, into the
larger bay. The contamination of the harbor and bay sediments by high concentrations of PCBs
and heavy metals has resulted in closing the area to lobstering and fishing, and has limited
recreational activities and harbor development.

Threats and Contaminants
PCBs and heavy metals, notably cadmium, lead, copper, and chromium, were
identified in sediments, soil, and marine life. The major public health risks involve
coming into direct contact with contaminated sediments and ingesting contaminated
fish and shellfish from the area. Levels of PCBs in some fish and lobsters at the site
exceed the Food and Drug Administration's (FDA) limit for PCBs in food. There is
an increased risk of cancer for people who repeatedly eat PCB-contaminated seafood
from the harbor and estuary. Currently, fishing is restricted to minimize this risk. The
risk to plant or animal life is greatest for bottom-dwelling organisms that have direct
contact with contaminated sediments.
, July 1995
-------
Cleanup Approach
This site is being addressed in four stages: initial actions and three long-term remedial phases
focusing on the hot spot area, the Acushnet River and New Bedford harbor, and the Buzzards
Bay Area.
Response Action Status
Initial Actions: In 1982, the Coast Guard erected signs warning the public of the
presence of PCBs in the harbor and industrial areas. The Commonwealth intensified
efforts to restrict access to the harbor. Bilingual warning signs in English and
Portuguese were posted along the New Bedford and Fairhaven shoreline. When the signs were
destroyed by winter weather, the EPA replaced them. In 1985, 2,000 feet of chain-link fence at
two recreational facilities were erected to keep people out of the contaminated areas. In 1992,
additional signs with warnings in English, Portuguese, and Spanish were installed along the
shoreline.
Hot Spot Area: In 1985, the Army Corps of Engineers (Corps) and the EPA began
to evaluate alternatives for addressing harbor contamination. In 1988, the investigation
was expanded, allowing the Corps to conduct demonstrations of dredging equipment
and construction and testing of disposal facilities in the estuary, while continuing to carry out site
sampling, analysis, and research. Hydraulic dredges were tested, sediment disposal facilities were
built, and extensive environmental monitoring was conducted to determine whether removal and
construction activities could occur without spreading contaminants. The engineering study
conducted by the Corps was used by the EPA to design the cleanup approach for the site. The
EPA's selected remedy for the hot spot area includes removal and incineration of contaminated
sediments to permanently reduce the migration of contaminants throughout the harbor area.
Specifically, this remedy calls for the removal of 10,000 cubic yards of contaminated sediments
from the hot spot area, followed by dewatering of the sediments. Wastewater produced during
dewatering will be treated prior to discharge into the harbor. Contaminated sediments will be
treated at a transportable incinerator. The treated sediments, in the form of incinerator ash, will
be tested for leaching of toxic metals. If the testing indicates that treatment is required to
immobilize the metals, the incinerator ash will be solidified before it is placed into a lined
shoreline landfill and covered with an impermeable membrane and vegetated cover. While work
progressed in preparation for dredging and incineration of the hot spot sediments, local
opposition to the incineration component of the project increased. In September 1993, the EPA
asked the U.S. District Court to overturn a local ordinance restricting the transport of wastewater
treatment equipment and incinerator components. In a settlement approved by the court, the EPA
was granted unimpeded access to the site and agreed to participate in mediated discussions with
local representatives opposed to incineration. The wastewater treatment plant is complete,
dredging of hot spot sediments began in 1994 and is scheduled for completion by 1995. A water
quality monitoring system was implemented to ensure that the dredging was done in a safe and
protective manner. Due to local concerns about incineration, however, the EPA has elected to
postpone the incineration component of the hot spot remedy, and explore alternative treatment
technologies. The dredged sediment is being held in a lined and covered holding pond until
treatment takes place; decanted seawater from the sediments is treated on site. Pilot studies of
alternative technologies are planned for the fall of 1995.
July 1995 2 NEW BEDFORD SITE
-------
Acushnet River & New Bedford Harbor: The EPA is currently evaluating
different alternatives for cleaning up this portion of the site. Many comments on the
study were submitted, primarily by the potentially responsible parties. The EPA plans
to issue a proposed cleanup plan for this area in 1995, after which design and construction of the
cleanup activities will begin.
Buzzards Bay Area: The EPA plans to initiate additional investigations of this area
of the site (south of the hurricane barrier) to determine if additional cleanup is
necessary.
Site Facts: In 1982, the EPA entered into Consent Agreements with two companies to address
the PCB contamination on their properties. The EPA, the Commonwealth of Massachusetts, and
five companies that used PCBs have reached settlement regarding the EPA's claims.
Environmental Progress
Posting warning signs, fencing contaminated areas, dredging the hot spot area sediments, and
investigating alternatives to incineration are reducing the threat posed by the site while further
investigations leading to the selection of final cleanup remedies are being conducted.

The Norwood PCBs site is located on 26 acres of mainly commercial and industrial properties.
The site is bordered by Route 1, the Dean Street access road, Meadow Brook, Pellana Road, and
Dean Street. The site consists of several parcels of land, including the Grant Gear facility, which
currently produces gears for industry; properties in Kerry Place; an automobile dealership; and
associated parking areas and adjacent fields. In 1979, the site was subdivided. The northeastern
portion of the site, approximately 9 acres in size, was purchased by Grant Gear Realty Trust and
leased to Grant Gear Works, Inc. The southern and western portions of the site were further
subdivided, a major portion of which was named Kerry Place. Most of the lots now are occupied
by commercial and light industrial buildings. Beginning in the 1940s, previous owners or
operators of the Grant Gear building used polychlorinated biphenyls (PCBs) in the production of
electrical transformers and other electrical components. In 1983, the State detected high levels of
PCBs in the soil on the site, and the EPA conducted an emergency removal of contaminated soil.
Approximately 8,000 people live within 1 mile of the site.

Threats and Contaminants
Groundwater is contaminated with PCBs and volatile organic compounds (VOCs) such
as trichloroethylene (TCE) and vinyl chloride. Soil and sediments are contaminated
with PCBs, polycyclic aromatic hydrocarbons (PAHs), and heavy metals. People are
at risk when coming into direct contact with or accidentally ingesting contaminated
groundwater, soil, and sediments. Increased risk may be posed if on-site groundwater,
left untreated, were used as a drinking water source. The concentrations of PCBs in
the sediments in Meadow Brook may pose an increased risk to aquatic organisms.
Exposure to PCB-contaminated soils also may pose a threat to animal life inhabiting
the site area.
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 1983, the EPA conducted an emergency removal of over 500
tons of highly contaminated soil from the site and transported it to an approved
disposal facility. In 1986, the Commonwealth installed a 4-foot-high wire mesh fence
around a IVa-acre portion of the northwestern and southwestern corners of the Grant Gear
property and covered contaminated soils within the fenced areas. The cover consisted of a
filter-fabric liner and 6 inches of crushed stone.
Entire Site: The remedies selected by the EPA to clean up the site include
excavating soils, dredge material, and sediments; treating them by solvent extraction
of PCBs and disposing of them on site; flushing or replacing the site drainage system;
cleaning equipment surfaces; collecting groundwater and removing the contaminants using air
filtering to convert volatile chemicals to a gas (activated carbon will be used before or after the
air filtration step to remove PCBs); and restoring the wetlands after minimizing the effects on the
wetlands during the cleanup of Meadow Brook sediments. Cleanup of groundwater contamination
began in 1994 and is scheduled to continue until 1996. The EPA is preparing the technical
specifications and design for the remainder of the cleanup, which is expected to begin in 1995.
Site Facts: The Commonwealth originally investigated the site in response to a telephone call
from an area resident.
Environmental Progress
The initial cleanup actions described above have removed contaminated sources and restricted
access to the site, thereby reducing the potential of exposure to hazardous substances at the
Norwood PCBs site while final cleanup activities are being planned and conducted.

The Nyanza Chemical Waste Dump site is a 35-acre parcel of land located adjacent to an active
industrial complex. From 1917 to 1978, the site was used to produce textile dyes, intermediates,
and other products. Nyanza, Inc., operated on this site from 1965 until 1978, when it ceased
operations. Large volumes of industrial wastewater containing high levels of acids and numerous
organic and inorganic chemicals, including mercury, were generated by these companies. Some
of the wastes were partially treated and discharged into the Sudbury River through a small
stream, referred to as Chemical Brook. Over 45,000 tons of chemical sludges generated by
Nyanza's wastewater treatment processes, along with spent solvents and other chemical wastes,
were buried on site. The area that contains the largest amount of buried waste and exposed
sludge is referred to as the Hill section. The current owner leases the old plant grounds to
various businesses. Approximately 10,000 people live within 3 miles of the site.

Threats and Contaminants
m
The groundwater, soil, sediments, and surface water are contaminated with heavy
metals and chlorinated organics. The groundwater and soil are also contaminated with
spent solvents and chemical wastes. Health threats include direct contact with and
accidental ingestion of contaminated surface water, groundwater, or soil. Wetlands
nearby and fish in the Sudbury River are contaminated with mercury. Two
downstream reservoirs, designated as backup water supplies, also contain sediment
with high mercury contamination levels.
July 1995
-------
Cleanup Approach
This site is being addressed in five stages: initial actions and four long-term remedial phases
focusing on source control and cleanup of the soil, off-site groundwater, wetlands and
drainageways, and the Sudbury River.
Response Action Status
Initial Actions: In 1987 and 1988, the EPA excavated an underground storage vault
containing 12,025 tons of material; 300 tons of contaminated soils were incinerated,
and an additional 356 tons of soils were excavated and disposed of off site.
Source Control and Soil: The remedy selected by the EPA to control the source of
the contamination and to clean up the soil includes excavating all outlying sludge
deposits and contaminated soils and sediments associated with these deposits,
consolidating this material with the Hill sludge deposits, capping the Hill section to prevent water
from entering it and spreading contaminants, constructing a groundwater and surface water
diversion system on the upgradient side of the Hill area, backfilling the excavated areas to
original grade, establishing a vegetative cover in the wetland areas, and constructing a more
extensive groundwater monitoring system to allow for future evaluation of the cap.
Approximately 60 percent of the 13-acre cap in an area of existing lagoons, sludge pits, and
buried building debris was covered with earth from on-site excavations in clean areas. The
remaining portion of the area to be capped was excavated to bedrock to create a cell for the
disposal of contaminated soils and solidified sludges from the on- and off-site cleanup areas. The
site was fenced. More than 65,000 cubic yards of contaminated soil were excavated and placed in
the cell in 1990. Final construction of the site cap was completed in 1991. All cleanup actions
were completed in late 1992.
Off-site Groundwater: The EPA selected a remedy to clean up the off-site
groundwater contamination in 1991. The selected remedy was to pump and treat the
contaminated groundwater from most contaminated portions of the plume for five
years. Once this is completed, the EPA will determine whether additional cleanup measures are
necessary. Technical design for the selected remedy began in early 1992. Two technologies are
being considered for cleanup of the groundwater. Both will be pilot tested in 1996. Final cleanup
actions are expected to begin in 1997.
Wetlands and Drainageways: Preliminary sampling showed that sediment and
surface water of the wetlands and drainageways between the site and the Sudbury
River are.contaminated with heavy metals. A decision was reached in 1993 to
excavate and landfill contaminated sediments from these wetlands. The design of the remedy is
currently underway and is expected to be completed in late 1996.
Sudbury River: After initial investigations of the contamination in the Sudbury
River, the EPA determined that additional studies were warranted. The initial
investigation showed that sediments and fish are contaminated with mercury and other
heavy metals. Additional studies of mercury and mercury cycling in the river system began in
1994 and will continue for several years.

-------
Environmental Progress
The excavation of contaminated soil and capping of the Hill area of the site have reduced the
potential of exposure to hazardous substances by controlling contamination migration and
isolating wastes. In 1992, the EPA re-posted the river with signs warning against the
consumption of contaminated fish. These actions have made the Nyanza Chemical Waste Dump
site safer while remaining cleanup actions are being planned.

Site Description
The Otis Air National Guard/Camp Edwards site covers approximately 21,000 acres and today is
known as the Massachusetts Military Reservation (MMR). Although the occupants and property
boundaries have changed several times since MMR was established in 1935, the primary mission
has always been to provide training and housing to Air Force or Army units. A review of past
and present operations and waste disposal practices identified numerous potentially contaminated
areas, including eight that cover 3,900 acres on the southern portion of MMR. Six of the eight
areas are located within Otis Air National Guard Base property boundaries: Former Fire Training
Area, Current Fire Training Area, Base Landfill, Non-destructive Testing Laboratory Leach Pit,
Fly Ash Disposal Area, and a plume of contaminated groundwater from a sewage treatment
plant, which extends 3 miles south. The two remaining waste areas, the Unit Training Equipment
Site and Property Disposal Office Storage Yard, are located at Camp Edwards, which currently is
leased to the Army. The materials found at the eight areas are fly ash, bottom ash, waste
solvents, waste fuels, herbicides, and transformer oil. While the Non-destructive Testing
Laboratory operated from 1970 to 1978, waste solvents, emulsifiers, penetrants, and
photographic developers were deposited in the sewer system. Effluent from the sewage treatment
plant was discharged into sand beds where it seeped into the groundwater. In 1984, the U.S.
Geological Survey detected contaminants in the monitoring wells downgradient of the plant. In
1983 and 1984, the Air Force detected volatile organic compounds (VOCs) in on-site monitoring
wells near the Base Landfill and Current Fire Training Area. Monitoring by the Air National
Guard and the State Department of Environmental Quality has detected VOCs in more than 200
private wells and in one Town well. The EPA has designated the Cape Cod Aquifer underlying
MMR as a sole source aquifer under the Safe Drinking Water Act. The municipalities of Bourne
and Sandwich and the Air Force base have an estimated population of 36,000 people and have
drinking water wells within 3 miles of hazardous substances at the site. Irrigation wells also are
located within 3 miles. Ashumet Pond, located less than 1 mile from the Former Fire Training
Area, is used for recreational activities.

Remaining Priority One, Two, and Three Areas; and groundwater plumes.
Response Action Status
Initial Actions: In 1986, water lines were installed to private residences affected by
groundwater contamination. In 1990, contaminated sediment was pumped from the
site and removed.
Chemical Spill Area Ten: The National Guard Bureau (NGB) is studying the
nature and extent of contamination at the site. The investigation will define the
contaminants and will recommend alternatives for cleanup. The study is expected to
be completed in 1995.
Chemical Spill Area Four: In 1992, the remedy for cleaning up the Chemical Spill
Area Four was selected. The remedy calls for a groundwater extraction and treatment
system. The system has been installed and began operation in late 1993. It is
expected to continue operating through 1995.
Fuel Spill Area Two: The NGB currently is investigating the contamination at this
area to determine the best cleanup strategy. The study is scheduled to be completed
in late 1995.
Fire Training Area One: The NGB is conducting a study of the area to define the
contaminants and to recommend alternatives for final cleanup. A removal action is

miles northwest of Plymouth Center
The Plymouth Harbor/Cannon Engineering Corp. site covers 2l/2 acres in Cordage Industrial
Park. The site is located near the Town of Plymouth. The facilities on site consisted of three
above ground storage tanks and the foundation of a razed building. Each storage tank was
surrounded by a 6- to 8-foot-high earthen berm. The northernmost tank was located about 50 feet
from Plymouth Harbor, while the central and southern tanks were located about 180 feet from the
Harbor. The storage tanks were originally constructed in the 1920s and used for storing fuel and
oil that were unloaded from barges. In 1975, the company obtained a license to store motor oils,
industrial oils and emulsions, solvents, lacquers, organic and inorganic chemicals, cyanide and
plating wastes, plating sludge, oily solids, pesticides, and clay and filter media with chemicals.
Cannon Engineering Corp. transported and stored hazardous wastes at the Plymouth facility and
incinerated the wastes at its Bridgewater facility until 1980, when the facilities went into
receivership. Approximately 50,000 people live in the two communities surrounding the site;
33,000 people live within a 3-mile radius of the site, and about 300 people work within l/2 mile
of the site. The area has a number of beaches, summer cottages, public recreation, and tourist

Cleanup Approach
Response Action Status
Immediate Actions: In 1983, Salt Water Trust removed the contents of and then
cleaned and decontaminated the south tank. The EPA removed the contents of the
central tank. A total of 44,022 gallons of oil-phase waste and 139,877 gallons of
aqueous-phase waste were transported to disposal facilities for incineration. Sludge pumping
operations began at the completion of the oil and aqueous waste removal. An estimated 52,750
gallons of sludge and 8,000 gallons of toluene were removed from the tanks and shipped for
disposal at an approved facility.
Source Control: The remedies selected by the EPA in 1985 included removing the
tanks and their pipes and disposing of them at an approved facility; conducting
additional soil sampling at the site to determine the distribution of contaminants;
sampling of groundwater, surface water, and sediment near the site; and assessing flood plains to
determine possible effects on cleanup actions. In 1986 and 1987, the EPA cleaned the interiors of
the three empty storage tanks and dismantled them. The pipework, foundations, and 33 drums of
wastes already on the site were transported to a licensed disposal facility. Soil was excavated
from two locations on the site, placed in drums, disposed of, and replaced with clean fill. Once
the tanks and other materials were removed, the EPA sampled soil, groundwater, surface water,
and sediments for the presence and distribution of remaining contamination at the site. A Flood
Plains Assessment Report was prepared and evaluated for the site. The site was fenced at that
time. All cleanup activities were completed in late 1987.
Sampling Program Investigations: The EPA studied the results of the sampling
program to evaluate any possible human health and environmental risks. Based on
this evaluation, the EPA is satisfied that the site poses no threat to human health and
the environment. The Final Site Close Out Report, filed in May 1992, confirms the EPA's
findings.
Site Facts: A history of complaints of odors and reports of leaks from the storage tanks on the
site prompted the State and the EPA to investigate the site. In 1983, a Consent Agreement was
reached with Salt Water Trust, the owners of the site. In accordance with the agreement, the site
owners cleaned the south tank, and the EPA cleaned the central tank.

Threats and Contaminants
Shallow groundwater contamination consists mostly of volatile organic compounds
(VOCs) including benzene and methylene chloride. Polychlorinated biphenyls (PCBs),
including Aroclor-1248 and Aroclor-1260, and lead have been found in soil samples.
The surface water and oil in the dikes contain the heavy metals arsenic and lead, as
well as benzene and PCBs. Oil in a rainwater catch basin contains PCBs and
tetrachloroethylene. Contaminants have been detected in the soils and shallow
groundwater in the nearby wetlands. The site is located in a 100-year flood plain,
providing conditions for flooding to wash contaminants from the site into the Quaboag
River. People may be exposed to contaminants by inhaling polluted air emanating
from the site, coming in direct contact with or accidentally ingesting contaminated
water or soil, or by eating contaminated fish.
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 tanks were emptied of over 1 million gallons of hazardous
wastes between 1979 and 1984. In 1986, the State Department of Environmental
Protection (DEP) cleaned and removed the tanks. The DEP also fenced the site in
1986. The EPA completed the repair and reinforcement of the fence in the fall of 1991. The
repair was necessary to limit unauthorized access and to extend the fence to include the debris
pile and spill area on the western and southern sides of the site. Warning signs also were posted
along the fence and on facility buildings.
Entire Site: The DEP has studied the nature and extent of the contamination at the
site. The investigation defined the contaminants and recommended alternatives for the
final cleanup. The study was completed in May 1991, and a proposed plan for
cleanup was distributed for public comment. The remedy, selected in 1992, calls for the use of
in-place stabilization of the on-site contaminated soils and sediments, followed by capping. The
engineering design of the remedy began in late 1994 and is scheduled for completion in mid-
1996.
Site Facts: In 1982, acting under authority of the Clean Water Act, the EPA asked the owner
to contain the oil discharge, determine the contents of 22 tanks, and investigate the possibility of
groundwater contamination. The owner complied with all requests. In 1994, the EPA, the
Department of Justice, and the State Attorney General's Office announced a settlement with
approximately 165 potentially responsible parties who have agreed to pay $6 million to cover past
costs and the cost of cleaning up the site.
Environmental Progress
The removal of hazardous wastes and installation of a fence have reduced the potential of
exposure to hazardous substances at the PSC Resources area while further cleanup activities are

Site Description
The Re-Solve, Inc. site is a former waste chemical reclamation facility situated on 6 acres of
land. Between 1956 and 1980, Re-Solve handled a variety of hazardous materials, including
solvents, waste oils, organic liquids and solids, acids, alkalines, inorganic liquids and solids, and
polychlorinated biphenyls (PCBs). Residues from the distillation tower, liquid sludge waste,
impure solvents, and burned tires were disposed of in four on-site unlined lagoons. The lagoon
contents were burned periodically to reduce the volatile organic compounds (VOCs) content. An
oil waste that accumulated at the bottom of the degreaser distillation still was disposed of on one
portion of the site through landfarming. This oil waste also was spread throughout the site to
control dust. Cooling water from the distillation tower was discharged to a shallow on-site
lagoon. In 1974, the State issued Re-Solve a license to collect and dispose of hazardous waste. In
1980, the State agreed to accept Re-Solve's offer to surrender its disposal license on the condition
that all hazardous waste be removed from the site. In 1981, legal action resulted in all drums,
debris, and buildings being removed, but the contents of the four lagoons remained.
Approximately 300 people live within a 1-mile radius of the site. Two residences are located
within 150 yards of Re-Solve. The Re-Solve, Inc. site is bounded by wetlands, and the land
surrounding the site is predominantly zoned for single family residential use. The bottoms of the
lagoons are situated in the water table, and some contaminants have migrated to groundwater. All
residences obtain their water from private wells located on their property.
Site Responsibility:
This site is being addressed through
Federal, Commonwealth, and
potentially responsible parties' actions.

Threats and Contaminants
Groundwater is contaminated with VOCs, PCBs, and lead. Sediments are
contaminated with PCBs and arsenic. Soil contains PCBs, arsenic, and VOCs
including trichloroethylene (TCE), vinyl chloride, methylene chloride, and toluene.
Surface water is contaminated with PCBs and VOCs. Fish from the river and ponds
contain PCBs, zinc, and mercury. Trespassers may be at risk by coming into direct
contact with or accidentally ingesting contaminated soil, sediments, groundwater, or
surface water. Also, people who eat contaminated fish may be at risk. The Copicut
River, located about 500 feet from the site, has been designated for the protection and
propagation of fish, other aquatic life, and wildlife. The site is located over an aquifer
that serves as a recharge area for part of a nearby town where a new municipal well is
being planned. Contaminants are moving off site in surface water runoff and
groundwater.
Cleanup Approach
This site is being addressed in four stages: an emergency action and three long-term remedial
phases focusing on controlling the sources of contamination and cleanup of the entire site.
Response Action Status
Emergency Action: In 1985, the EPA removed sludges from the lagoons and
excavated approximately 16,000 cubic yards of contaminated soil for off-site disposal
in a federally approved landfill.
Source Control: To control the source of the contamination at the site, the EPA
selected a remedy that included removing the contents of the four unlined lagoons,
excavating soil from hot spots, and excavating soil from the former oil spreading
area for disposal at an off-site approved facility. The entire site was capped to prevent contact
with surface and groundwater. Approximately 16,000 cubic yards of soil was removed from the
site. These remedies were completed in 1987. In addition, the site was fenced to limit access to
the contaminated areas.
July 1995 2 RE-SOLVE, INC.
-------
Additional Source Control Measures: The remedies selected by the EPA to
prevent the additional migration of contaminants include excavating 22,500 cubic
yards of PCB-contaminated soil located above the groundwater table; treating the soil
on site by removing the contaminants using dechlorination, and then placing the soil back on site
with 18 inches of gravel capping; excavating 3,000 cubic yards of PCB-contaminated sediments
from wetland areas and treating them through dechlorination; conducting studies to determine if
the dechlorination process can be used on a full-scale level; and restoring the wetlands. Also,
emissions from the soil excavation and treatment will be monitored, and groundwater and surface
water will be monitored quarterly to evaluate the effectiveness of the cleanup. The technical
specifications and design for the cleanup were prepared by the parties potentially responsible for
site contamination under EPA supervision. The pilot soil treatment plant began operations in
1992. As a result of the pilot studies, the EPA modified the soil/sediment treatment technology to
low thermal desorption in place of dechlorination followed by off-site incineration of the desorped
contaminants. From mid-1993 to mid-1994, the parties potentially responsible for site
contamination, successfully excavated and treated 36,000 cubic yards of PCB-contaminated soils
and sediments, and approximately 75 cubic yards of desorped contaminants were sent off site for
incineration. In addition, approximately one acre of wetlands surrounding the source area were
restored. The treated soil was backfilled, and the site graded and covered with 18 inches of
crushed stone. Final activities are scheduled to be completed by late 1995.
Entire Site: Remedies selected to address contamination at the rest of the site
include pumping the groundwater to keep the contaminant plume from moving;
treating groundwater by exposing it to the air to evaporate the contaminants and
using carbon filters to recapture the contaminants; discharging the treated water back into the
aquifer; monitoring the groundwater, surface water, and wetlands; and restricting the future use
of groundwater. A pilot test addressing the management of contaminant migration was completed
in 1990. The design for the selected cleanup remedies is being performed by the potentially
responsible parties and is scheduled to be completed in early 1996. Fish sampling will be
performed at downgradient stations. Drinking water wells also will be monitored for traces of
contamination. The clean up of PCB-contaminated sediments will require temporarily disrupting
the wetlands. These effects are unavoidable; however, a wetlands restoration program will be
implemented following completion of the cleanup activities. A plan for the wetlands restoration is
currently being developed as part of the cleanup design phase.
Site Facts: A Consent Decree was signed in 1988 under which the parties potentially
responsible for site contamination agreed to conduct the cleanup activities and to reimburse the
government for past costs and future oversight costs.
Environmental Progress
Removing the contamination sources such as soils and sludges from the site, along with
restricting access to the site with a security fence, have reduced the health risks and
environmental threats posed by the Re-Solve, Inc. site while final cleanup actions are being
planned.

Site Description
The Rose Disposal Pit site is a IV^-acre waste disposal area. The site occupies a section of a
14-acre residential lot bordering Balance Rock State Park, which is forest land, and the former
Balance Rock Cafe; cropland and pastures also are nearby. Beginning in 1951 and continuing
through 1959, waste oils and solvents from the General Electric (GE) Plant in nearby Pittsfield
were disposed of in an open trench at the site. In 1980, the State Department of Environmental
Quality Engineering inspected the site and found 15,000 cubic yards of soil contaminated with
polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs). Two plumes of
contaminated groundwater were discovered moving to the east and south away from the disposal
area. Approximately 100 people live within a mile of the site and may be affected by the
contaminated drinking water.

The groundwater is contaminated with PCBs and VOCs including trichloroethylene
(TCE), benzene, and vinyl chloride. The contaminant plumes extend from the pit
eastward into the park and to the south, and are carried off by a small unnamed
stream. The sediments, soil, and surface water at the site and a nearby wetland were
contaminated with PCBs and VOCs. VOCs, as well as vinyl chloride were found in
downgradient drinking water wells.
July 1995
-------
Cleanup Approach
Response Action Status
Initial Actions: GE erected a storm fence and covered the site with plastic in 1984.
GE then pumped out a pocket of contaminated oil found beneath the surface to
prevent rain or snow from further spreading the contamination. An alternate
permanent water supply also was provided to the restaurant and those residences affected by the
contaminated plume.
Source Control and Migration Management: The selected remedy controls the
source of contamination and manages the migration of contaminants. GE has
performed all cleanup work. The remedy included excavation and on-site incineration
of approximately 51,000 tons of contaminated soil and sediment. Soil in the disposal area was
excavated below the water table. The intent of treating soils in the saturated zone was to remove
PCBs from the source area. Migration of contaminants was controlled by active restoration of the
shallow aquifer by air filtering the VOCs to a gas, and then using carbon adsorption to remove
the airborne contaminants. Groundwater is being treated to reduce contaminants to levels that will
meet drinking water standards. Sediments and surface water in the small pond located near the
disposal area also were treated, and the pond was restored to its original wetlands character after
cleanup. Incineration involved the use of an innovative form of on-site incineration that included
an initial thermal extraction phase instead of chemical extraction to separate contaminants from
the soil. Treatment of the VOCs rendered the PCBs relatively immobile in the saturated zone of
the disposal area. Construction activities began in early 1993 and were completed in 1994.
Groundwater will continue to be treated until drinking water standards are met.
Site Facts: In 1984, the EPA issued a joint enforcement order requiring GE to conduct removal
activities at the site. In 1989, the EPA and GE signed a Consent Decree for the company to
perform the cleanup and to reimburse the EPA for past and future oversight costs.
Environmental Progress
The installation of a fence, the covering of the site, the provision of an alternate water supply,
and treatment of contaminated soil, sediments and surface water have eliminated the potential of
exposure to hazardous materials in these media. All construction activities have been completed at
the Rose Disposal Pit site. Groundwater treatment will continue until drinking water standards are
met.

Site Description
From 1946 through 1969, 4 acres of the 235 Salem Acres site received sludge, grit, and grease
from the South Essex Sewerage District through an agreement with the owners. This sludge
contained tannery waste. The sludge was placed in eight unlined, uncovered disposal pits.
Polychlorinated biphenyls (PCBs), volatile and semi-volatile organic compounds, arsenic, and
chromium were found to be present in the pits. Residential housing borders the site on the south
and the east. Approximately 65,000 people live within 1 mile, and 127,000 people live within 3
miles of the site. One of the disposal pits is located approximately 20 feet from Strongwater
Brook. The site lies on the divide of two drainage basins that channel both surface water and
ground water directly into two major aquifers.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/15/84
Final Date: 06/10/86
Threats and Contaminants
The on-site soils and sludge are contaminated with PCBs, volatile and semi-volatile
organic compounds, arsenic, and chromium. The sludge pit areas are now fenced, and
access to them is restricted. Emergency capping of the pits in 1987 by the EPA has
largely eliminated them as a current source of exposure. There is also a landfill and
fly ash pile at the site. These remain uncapped and the potential contact or ingestion
of these uncapped contaminants pose a health risk.
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.
July 1995
-------
Response Action Status
Initial Actions: In 1988, the EPA covered the sludge pits with a high density,
polyethylene synthetic cap, removed the liquid wastes from the disposal pits to an
off-site storage facility, and constructed concrete cut-off walls to prevent further
releases into the wetlands. In 1990, repairs were made to a monitoring well and a security fence
on site, and signs were posted to further restrict access.
Entire Site: The South Essex Sewerage District completed an investigation into the
nature and extent of the soil and sludge contamination in early 1993. The
investigation defined the contaminants of concern and recommended alternatives for
final cleanup. The EPA selected a final remedy for the site, which includes sludge-fixation with
fly ash and other substances such as cement and soil, as necessary. A contingent remedy
includes the installation of an EPA-approved cap. After treatment, the sludges from the lagoons
will be taken off site to a municipal landfill. The fly ash and "old landfill" on site also will be
treated as necessary, excavated, and taken off site to a municipal landfill. The design of the
cleanup remedies is underway by the potentially responsible parties, and is expected to be
completed in 1996.
Site Facts: On May 26, 1987, the EPA signed a Consent Order with the South Essex Sewerage
District to have the District perform the studies to examine the nature and extent of contamination
and present technical options for cleanup. In December 1993, the EPA signed a Consent Decree
with the South Essex Sewerage District to clean up the lagoons. The EPA also signed a separate
Consent Decree with the Massachusetts Electric Company to clean up the fly ash pile on site. In
October 1994, the EPA signed a Consent Order with Ugo DiBase, the remaining party, to clean
up the landfill and three debris piles.
Environmental Progress
The EPA has assessed conditions at the Salem Acres site and has determined that the initial
capping and liquid waste removal actions, combined with the site security measures taken, have
reduced the potential for exposure to contamination while final cleanup remedies are being
designed.

The Shpack Landfill covers 8 acres, 51/2 acres of which are within the Town of Norton, and the
remaining 21/2 acres are in the City of Attleboro. The landfill was operated from 1946 until
1965, when a court order forced its closing. This landfill received domestic and industrial waste,
including inorganic and organic chemicals, as well as radioactive waste. The area near the site
includes a wooded swamp. Approximately 40,000 people live within a 3-mile radius of the site.
Municipal water supplies for both townships do not extend to the area around the site. Therefore,
residents in this area use private drinking water wells, most of which withdraw water from the
bedrock aquifer. The distance from Shpack Landfill to the nearest residential well is about 150
feet. There are 27 private wells within a mile of the site that serve 103 people. The two
municipal water supply well fields for Norton are situated in the shallow aquifer and are located
3 miles east and 51/4 miles northeast of the area. Municipal well fields for Attleboro also are

to individuals.
Cleanup Approach
This site is being addressed in two stages: interim actions and a long-term remedial phase
focusing on cleanup of the entire site.
July 1995
-------
Response Action Status
Interim Actions: Before the site was listed on the NPL, the State removed all
chemical wastes in above-ground storage containers, fenced the site, and dismantled
buildings. In 1983, the EPA monitored the air and sampled soils, and found
contamination both on site and off site. In 1984, the EPA raised the height of the fence from 6 to
8 feet and covered highly contaminated areas with 9 inches of crushed gravel and a clay cap. In
1986, damage to the original fence was repaired. Subsequent sampling revealed an additional area
of soil contamination that the EPA enclosed. In 1986, the EPA discovered dioxin; the fence was
relocated to prevent public access, and a temporary gravel cover was laid over the dioxin-
contaminated soil to prevent contact.
Entire Site: The potentially responsible parties and the EPA conducted investigations
into the contamination and assessed the alternative technologies for cleanup. Activities
included: groundwater, surface water and sediments sampling; monitoring; well
installation; and sampling vents for air contamination. Surface soil testing and sampling beneath
the clay cap and outside the fence determined the extent of soil contamination. These activities
were completed in mid-1991, and remedies for final cleanup were selected by the EPA in late
1991. Soil will be treated by a vapor extraction system and through stabilization. Stabilized soil
will be capped. The groundwater will be extracted and treated by air stripping. These cleanup
activities are scheduled to last until late 1995. A pilot test of the soil vapor extraction system is
scheduled for late 1995.
Site Facts: The EPA negotiated with a group of potentially responsible parties to conduct
studies which determine the nature and extent of contamination and to develop alternative cleanup
technologies. In the past, some residents and doctors of the community had attributed health
effects to site contamination.
Environmental Progress
Initial actions to fence the site and to cap or cover areas of contamination have reduced the
potential for accidental exposure and the further migration of contamination from the Silresim
Chemical site. These actions have eliminated the immediate threats posed by the site while
cleanup activities are underway.

requirements of the Massachusetts Department of Environmental Protection. In 1992, during
demolition of a secondary containment area at the former sewage treatment plant, several empty
pesticide containers and two compressed gas cylinders (one was found to contain chlorine) were
unearthed. The soil, cylinders, containers, and debris were excavated. In addition the chlorine
cylinder was containerized and removed from the site.

The 12-acre Sullivan's Ledge disposal area, in the northwestern corner of New Bedford, operated
as a quarry until about 1932. In 1935, the City of New Bedford acquired the site through tax title
foreclosure. Between the 1940s and the 1970s, local industries used the quarry pits and adjacent
areas for disposal of hazardous material and other wastes including electrical capacitors, fuel oil,
volatile liquids, tires, scrap rubber, demolition materials, brush and trees. After a fire at the site
in the 1970s, the City backfilled the only existing open pit and covered all exposed refuse. In
1982, when the Massachusetts Department of Public Works drilled test borings as part of a plan
to build a commuter parking lot, electrical capacitors, which may have caused poly chlorinated
biphenyl (PCB) contamination, were unearthed. Approximately 98,500 people live within 3 miles

-------
Cleanup Approach
The site is being cleaned up in three stages: an initial action and two long-term remedial phases
focusing on cleanup of the Sullivan's Ledge Disposal Area and the Middle Marsh.
Response Action Status
Initial Action: The City of New Bedford erected a fence around the Sullivan's
Ledge Landfill from 1984 to 1985 to limit the potential for exposure to hazardous
materials at the site.
Sullivan's Ledge Disposal Area: The EPA has chosen the following remedies for
cleaning up the disposal area portion of the site: establish security measures, connect
the site to power lines, and furnish sanitary facilities; excavate, solidify, and dispose
of soils on the site; excavate and dispose of sediments from the stream and the golf course water
hazards; construct an impermeable cap over an 11-acre area to cover the quarry pits and contain
the contaminated surface soils and sediments that would be solidified and placed on site; divert
and line a portion of the unnamed stream to prevent water from being pulled into extraction
wells; install an active pumping system to collect contaminated shallow bedrock groundwater, a
passive collection system to collect contaminated seeps and shallow groundwater, and a treatment
system to treat collected groundwater; restore and enhance the wetlands to reasonably similar
hydrologic and botanical conditions that existed prior to excavation; monitor the site with 5-year
reviews; and use institutional controls to ensure that the bedrock groundwater will not be used for
drinking water since it cannot be cleaned to drinking water standards. The technical design of
these selected remedies began in 1991, and is scheduled to be completed in late 1995.
Middle Marsh: In 1989, the EPA began a study of the contamination in the Middle
Marsh sediments. In 1991, the EPA released results of the studies undertaken, which
indicated significant PCB accumulation in wildlife in and around Middle Marsh.
While sediments in the Marsh also were found to be heavily contaminated with PCBs, the threat
to human health was judged to be negligible. A decision on the appropriate cleanup remedy was
reached in late 1991. The EPA chose the following remedy for Middle Marsh: establish security
measures and clear the land; excavate contaminated sediments from portions of the Middle Marsh
and the adjacent wetland; screen and dewater the excavated sediments; dispose of the excavated
materials beneath the cap to be constructed at the Sullivan's Ledge Disposal Area; restore the
affected wetlands; use institutional controls to prevent future residential use of and restrict access
to the area; and establish a long-term environmental monitoring plan. In the event that the
Sullivan's Ledge Disposal Area would be unavailable for disposal, the EPA also selected a
contingency remedy which includes the same site preparation, excavation, wetlands restoration,
institutional controls and long-term monitoring as the remedy described above; however,
excavated sediments would be treated by solvent extraction and would be replaced within Middle
Marsh. The technical design of these selected remedies began in 1993 and is expected to be
completed in early 1996.

Site Description
The W. R. Grace and Company site covers approximately 200 acres. The site was the former
location of the American Cyanamid Company and the Dewey & Almy Chemical Company. These
companies produced sealant products for rubber containers, latex products, plasticizers, resins,
and other products. Operations at the W. R. Grace facility included the production of materials
used to make concrete, container sealing compounds, latex products, and paper and plastic
battery separators. Effluent wastes from these operations flowed into several unlined lagoons (the
Primary Lagoon, Secondary Lagoon, North Lagoon, and Emergency Lagoon), and solid and
hazardous wastes were buried in or placed onto an on-site industrial landfill and several other
disposal areas. These other waste sites include the Battery Separator Lagoons, the Battery
Separator Chip Pile, the Boil Lagoon, and the Tank Car Area. In addition, the by-products of
some chemical processes were disposed of in the Slowdown Pit. Since 1973, residents in South
Acton have filed complaints about periodic odors and irritants in the air around the W. R. Grace
plant. Investigations in 1978 indicated that two municipal wells, Assabet #1 and #2, were
contaminated. As a result of these findings, the Town took precautionary action and closed the
two wells. Discharge to all lagoons and the Battery Separator Area ceased in 1980. The site is
bounded in part by Fort Pond Brook and by the Assabet River.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.

Threats and Contaminants
Groundwater is contaminated with volatile organic compounds (VOCs) and heavy
metals including lead, arsenic, chromium, and nickel. Sediments are contaminated
with cadmium. The soil and sludge in the disposal areas are contaminated primarily
with arsenic and VOCS, including vinyl chloride, ethyl benzene, benzene, 1,1-
dichlorethylene, and bis(2-ethylhexyl)phthalate. Trespassers may be at risk by coming
in direct contact with or accidentally ingesting contaminated groundwater, surface
water, sediments, soil, or sludge.

Cleanup Approach
The site is being addressed in four stages: interim actions and three long-term remedial phases
focusing on aquifer restoration, landfill and lagoon closure, and residual contamination.
Response Action Status
Interim Actions: The parties potentially responsible for site contamination removed
tanks from the site in 1982 and 1983.
Aquifer Restoration: The potentially responsible parties have installed an aquifer
restoration facility. It has been in operation since 1985 to stop the discharge of
contaminated ground water into the Assabet River, Fort Pond Brook, and various
other ponds. Supplemental studies will be conducted in mid-1996 to evaluate the effectiveness of
the aquifer restoration facility. If necessary, modifications will be made to upgrade the facility.
Landfill and Lagoon Closure: The EPA's recommended cleanup plan includes:
excavating and transporting for off-site incineration the highly contaminated material
from the Blowdown Pit; excavating and stabilizing the material in the Blowdown Pit,
the Primary Lagoon, Secondary Lagoon, North Lagoon, and Emergency Lagoon by mixing it
with cement, lime, and fly ash to form a solid; excavating the soils from the Battery Separator
Lagoons, Boiler Lagoon, and Tank Car area; placing both the stabilized and non-stabilized
materials excavated from the site in the existing industrial landfill and covering these materials
with a cap to prevent surface water or rain water from coming into contact with the buried
contaminants; closing the Chip Pile area; modifying the Aquifer Restoration System to address
emission controls; and monitoring each area. The design for this remedy was conducted in phases
and completed in 1993. Construction was initiated in 1994.
Residual Contamination: An investigation is scheduled to begin in 1996 to
determine if any remaining contamination exists in the lagoons. If cleanup goals are
not met through the first set of remedies, other methods will be evaluated to address
the remaining contamination.
Site Facts: The company entered into a Consent Decree with the EPA in 1980 to conduct a
study of the site and to carry out cleanup activities.
Environmental Progress
Removing tanks and installing an aquifer restoration facility have reduced the potential for
exposure to hazardous substances in ground water and leaking tanks, making the W. R. Grace
area safer while cleanup activities are underway.

City of Woburn
Site Description
Wells G & H were two municipal wells developed in 1964 and 1967 to supplement the water
supply of the City of Woburn. The site covers a total area of 330 acres. The wells supplied 30
percent of the city's drinking water. In 1979, city police discovered several 55-gallon drums of
industrial waste abandoned on a vacant lot in the vicinity of the site; subsequently these drums
were removed. As a result of this discovery, the nearby wells were tested and found to be
contaminated. Both of the wells were shut down in 1979. Five separate properties on the site
were found to be the contributing sources of contamination to the aquifer that supplied the water
to these two municipal wells. The population of Woburn is approximately 36,600 people. The
area surrounding the site is predominantly residential. Some non-residential properties are fenced
to limit unauthorized access. The site includes commercial and industrial parks, as well as
recreational areas and some residential gardens. The Aberjona River flows through the middle of
the site. Surface water runoff from the site is directed through drainage systems toward the river
and its tributaries.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
The ground water is contaminated with volatile organic compounds (VOCs) including
trichloroethylene (TCE) and tetrachloroethylene (PCE). Sediments in the Aberjona
River are contaminated with polycyclic aromatic hydrocarbons (PAHs) and heavy
metals such as chromium, zinc, mercury, and arsenic. Soil is contaminated with
PAHs, polychlorinated biphynels (PCBs), VOCs, and pesticides. Children use an
undeveloped portion of Olympia Nominee Trust, located near the site, for riding dirt
bikes. People are at risk if they accidentally touch or swallow contaminated
groundwater, soil, or sediments in the Aberjona River. The site is located on land that
serves as a recharge area for the aquifer from which the Woburn Municipal Wells G
& H drew water.
July 1995
-------
Cleanup Approach
The site is being addressed in four stages: immediate actions and three long-term remedial phases
focusing on source control and contaminant migration, and cleanup of the central aquifer and the
Aberjona River.
Response Action Status
Immediate Actions: One of the parties potentially responsible for site
contamination secured their own property with a fence and a guard. Drums
containing PCB sludge and soil were removed to an approved facility. One of the
potentially responsible parties was required to investigate and remove the pure PCE found in a
well on their property.
Source Control and Contaminant Migration: The EPA's selected remedy
includes excavating and incinerating 2,100 cubic yards of contaminated soils on site
and backfilling the excavated areas; treating additional contaminated soil in place by
extracting soil vapors for treatment with activated carbon; and pumping contaminated
groundwater from the five source areas and removing the contaminants by using a stream of air
that is forced through the water. Contaminants removed by the air stream will be further treated
prior to being released into the atmosphere. The EPA negotiated with the potentially responsible
parties to prepare the technical specifications and design for the cleanup. The potentially
responsible parties have begun some and completed other pre-design activities at four of the five
properties. Design work and construction of groundwater treatment systems at two of the four
properties was completed in 1993. All remaining design work is expected to be completed in
1995. The two operating groundwater recovery and treatment systems recovered more than 25
million gallons of contaminated groundwater during their second year of operation. Excavation of
contamination at one of the properties led to off-site disposal of 67 tons of hazardous sludge, 354
tons of non-hazardous sludge, 255 tons of debris soils, 45 drum carcasses, and 987 tons of mixed
contaminant soils this year.
Central Aquifer: In 1993, three of the five parties potentially responsible for site
contamination began a study to explore the nature and extent of contamination in the
central aquifer area, which is beyond the various other source area property
boundaries within the Wells G & H site. The study will evaluate a way to cleanup the
contamination that has migrated from the source areas. Completion of the study is scheduled for
1997.
Aberjona River Study: The EPA is conducting an investigation into the risk to
human health and the environment within the Aberjona River and the upper Mystic
Lake. If risks are found, a more complete investigation of contamination and cleanup
alternatives will be undertaken. The investigation is expected to be completed in 1997.
Site Facts: The EPA has signed a Consent Decree with three of the potentially responsible
parties to conduct a study of contamination at the Central Aquifer area.
