How to Use the NPL Book
"«.
S-
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.

Off Houghton Lane
Site Description
The Bennington Landfill, located off Houghton Lane in Bennington, is a 15-acre municipal
sanitary landfill. The area was a sand and gravel pit until it began operation as a landfill in 1969.
The Town of Bennington purchased the site in 1985. Several Bennington industries dumped liquid
wastes into an unlined lagoon on the site from 1969 to 1975. Town records indicate that
polychlorinated biphenyls (PCBs), organic solvents, and lead were disposed of at the site. The
lagoon was closed in 1975; workers landfilled it after attempts to dry it up failed. An
underground drainage system built in 1976 is designed to lower the groundwater level below the
landfill. The system discharges through a culvert into an unlined, ponded area. In 1986, the
Vermont Department of Environmental Conservation detected contaminants in the groundwater
discharging from the culvert into the ponded area. Approximately 2,200 residents located within
3 miles of the site use private wells. The area surrounding the site is mainly rural residential.
Morgan Spring, a bedrock water source located 3 miles south of the landfill, is used regularly to
supplement the Bennington water system.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 03/31/89
Threats and Contaminants
Groundwater discharging through a culvert from the underground drainage system
beneath the site contains PCBs from contaminated landfill soils, heavy metals
including lead and arsenic, and volatile organic compounds (VOCs) including benzene
and xylene. The State believes that the ponded area had caught fire in the past. The
State found several flammable materials in it. The site is not completely fenced,
thereby reducing the potential for direct contact with contaminants. A freshwater
wetland is located 500 feet east of the culvert, and may be subject to contamination
from site runoff. Hewitt Brook, which originates from this wetland, is used for trout
fishing.
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 1994, the EPA and the potentially responsible parties began a
short-term action to minimize the migration of contaminants from the landfill into the
groundwater. These actions consisted of installing a composite, low permeability cap
with drainage controls over the site, excavating contaminated soils and sediments and
consolidating them within the existing landfill, collecting the site leachate, managing the landfill
gases, and providing site management and institutional controls.
Entire Site: A potentially responsible party began an investigation into the nature and
extent of contamination at the site in mid-1991. The study will assess the risks to
human health and the environment. The results of the study, expected in late 1995,
will be used to select cleanup remedies.
Environmental Progress
The initial actions underway at the Bennington Landfill site are reducing immediate threats while
site studies continue.

Landfill
Site Description
In the early 1960s, the 17-acre BFI Sanitary Landfill (Rockingham) site served as a borrow area
for the construction of Interstate 91. In 1973, Browning-Ferris Industries, Inc. (BFI) bought the
landfill from an individual who had started operations in 1968. State files indicate that industrial
wastes, including heavy metals, bases, pesticides, and volatile organic compounds (VOCs) were
deposited in the unlined disposal area from 1968 to 1979. In 1983, Vermont licensed the site as a
municipal landfill certified to accept hazardous waste from small quantity generators. The landfill
was closed in 1991. The Vermont Department of Environmental Conservation (VT DEC) reports
that nearby residential and monitoring wells downgradient of the site have been contaminated
since 1979. The contaminated residential wells are no longer in use. There are two leachate
collection ponds on site. A tar cap covers a portion of the landfill to prevent the infiltration of
rainwater; however, cracks in the cap have been observed, and it is covered with new refuse.
Approximately 2,700 people live within a mile of the site, and 6,400 residents live within 3
miles. Three homes near the site are supplied water from a water supply line provided by BFI.
The Connecticut River is located 560 feet to the east, along the drainage route of surface water
leaving the site.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/21/88
Final Date: 10/04/89
Threats and Contaminants
The soil and groundwater contain contamination from VOCs and heavy metals
including chromium, copper, lead. Drinking water from contaminated wells in the
area poses a threat to public health. The Connecticut River also may receive
contaminants from groundwater discharge, posing a threat to water quality and aquatic
life.
July 1995
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase directed
at cleanup of the entire site.
Response Action Status
Initial Actions: BFI is providing an alternate drinking water supply to residences
with contaminated wells. In 1989, BFI installed an active gas collection system to
control landfill gases. In early 1993, BFI also installed a groundwater inceptor trench
to collect surface water and leachate seeps that were discharging into the Connecticut River. In
1993, the EPA completed studies at the site and initiated an early action to address the source of
contamination under the Superfund Accelerated Cleanup Method (SACM). In 1994, the
potentially responsible parties capped the landfill and expanded the existing active gas and
leachate collection system.
Entire Site: In the fall of 1994, a remedy was selected to address the cleanup of the
groundwater. Through management of existing site controls, including the landfill
cap, active gas and leachate collection systems, and long-term monitoring, the
groundwater will clean itself naturally over time. Long-term monitoring of the groundwater,
surface water, and residential wells will continue to ensure that established cleanup levels are
met.
Site Facts: The State issued three orders to the owner between 1980 and 1983, requiring BFI to
determine the hydrogeology of the landfill, monitor on-site groundwater, and provide drinking
water to affected residents nearby. In July 1992, the EPA entered into an Administrative Order
on Consent with two parties, BFI, Inc. and Disposal Specialists, Inc., to perform the site
investigations. An Administrative Order by Consent was signed between the EPA and the
potentially responsible parties, BFI, Inc. and Disposal Specialists, Inc., to perform the initial
actions.
Environmental Progress
Installation of the landfill the cap and gas and leachate collection systems has reduced the
potential for exposure to contaminated soil and groundwater, making the BFI Sanitary Landfill
site safer while monitoring and natural restoration of groundwater continues.

Site Description
EPA REGION 1
Bennington County
Woodford
The 3-acre Burgess Brothers Landfill site is located on the Woodford and Bennington town line.
The site is still owned by the Burgess family and borders the Green Mountain National Forest.
Burgess Brothers Construction Company operated the facility as a sand pit, salvage yard, and
dump from the 1940s until the mid-1970s. The site is still operating as a salvage yard and a sand
pit. For 20 years, Union Carbide Corp.'s Bennington Plant disposed of wastes from battery
manufacturing at the site; an unknown quantity of lead sludge between 1956 and 1971, and the
equivalent of 47,780 drums of hazardous wastes from 1971 to 1976. The wastes were dumped
into and buried in unlined settling lagoons next to the sand pit bank. Studies conducted by both
the State and Union Carbide have determined that soils, groundwater, and surface water both on
and downgradient of the site are contaminated with heavy metals and volatile organic compounds
(VOCs). The site area is largely rural and is sparsely populated, but 13,900 people live within 3
miles of the site. Residents draw drinking water from private and public wells; the nearest well is
located 1/2 mile from the site. A spring used to supply drinking water to Bennington is 1 1/2
miles to the west of the site. Barney Brook and the Waloomsic River are located within 3 miles
downstream of the site; both are used for recreation. A freshwater wetland is located at the toe of
the landfill.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 03/31/89
Threats and Contaminants
Groundwater, surface water, and soils are contaminated with heavy metals, including
mercury and lead, and VOCs, including vinyl chloride and trichloroethylene (TCE).
The site is unrestricted; direct contact with contaminated soils or surface water is a
potential health risk. There are sensitive areas nearby, including freshwater wetlands
and National Forest land, both of which are used for recreational purposes and could
be polluted by site contamination.
July 1995
-------
Cleanup Approach
The site is being addressed in a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status
Entire Site: The potentially responsible parties began an investigation in 1991 to
determine the nature and extent of contamination. Recommendations for the selected
cleanup methods for soil, surface water, and groundwater will be offered at the
conclusion of this study, scheduled for early 1996.
Environmental Progress
The EPA has evaluated this site and determined that the site poses no immediate threat to public
health or the environment. Studies at the Burgess Brothers Landfill are being conducted while the
EPA continues to monitor the site.

Northeast portion of Lyndon
(Lyndonville)
Other Names:
Lyndonville Town Dump
The Darling Hill site is an inactive dump that occupies approximately 31/2 acres at the top of a
steep hill along Darling Hill Road in rural Lyndon. From 1952 to 1972, the Village of
Lyndonville leased and operated the dump. The dump was used for the disposal of light industrial
and municipal wastes. Ray O Parker and Son, Inc. of Lyndonville leased and operated the dump
from 1972 to 1983 and purchased it in 1983. During this time, the dump was used mainly for the
disposal of scrap wood, metal, demolition materials, and industrial wastes. The site continued
operating until the 1980s; in 1989 it was closed. An estimated 92,000 gallons of liquid industrial
wastes were dumped directly on the ground at the unlined site, as were 2,000 tons of liquid,
semi-liquid, and solid industrial wastes including metal-plating rinse water, alkali degreasers, and
organic solvents. The depth to groundwater below the dump is more than 100 feet. The village
well field, serving 3,200 people, is 1/2 mile to the southwest of the dump. An additional 460
people used private wells within 3 miles of the site. About 300 feet west of the site, and down a
steep hill, is the West Branch of the Passumpsic River, which meets the East Branch
approximately 1/2 mile further south. The river is used for recreational fishing and boating.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible

NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 10/04/89
Threats and Contaminants
Metal plating rinse waters, alkali degreasers, and organic solvents were dumped on
the ground at the site. However, the EPA has determined that the low levels of
volatile organic compounds (VOCs), including trichlorethylene (TCE) and toluene in
the groundwater and soil, do not pose a risk to public health or the environment
because of the use of the carbon filtration system on the municipal water supply.
July 1995
-------
Cleanup Approach
Response Action Status
Initial Actions: The Darling Hill Dump was closed in 1989. In 1991, the potentially
responsible parties, under EPA oversight, installed a carbon filtration system to
ensure a safe municipal water supply.
Entire Site: In 1992, following an investigation into the nature and extent of
contamination at the site by the potentially responsible parties and a public comment
period, the EPA determined that, because of the success of the initial actions, no
further actions were necessary at the site. The EPA concluded that the low levels of contaminant
concentrations in the soil and groundwater do not pose a threat to people or the environment. The
Village of Lyndonville now operates the carbon filtration system as needed to ensure that the
municipal water supply remains safe. Monitoring of private wells and the municipal water supply
continues to ensure the long-term effectiveness of the initial actions.
Site Facts: Two Consent Orders were signed in 1989 requiring the parties potentially
responsible for the site contamination to perform an investigation and install a carbon filtration
system at the municipal well field. The Consent Order to remove contaminants from the
groundwater was terminated due to the low levels of contamination found during the site study.
The Village of Lyndonville now operates the carbon treatment system, as necessary.
Environmental Progress
Construction of all cleanup remedies is complete. Installation of a carbon filter in the municipal
water supply by the potentially responsible parties helps ensure that the groundwater remains
within Federal drinking water standards. The operation of the carbon filtration system was turned
over to the Village of Lyndonville, which continues to monitor the groundwater.

EPA REGION 1
Windsor County
Springfield
Site Description
The Springfield Landfill site covers 10 acres of a 30-acre parcel of land. The landfill was
operated by the Town of Springfield between 1947 and 1968 for the disposal of municipal solid
waste and hazardous industrial liquid and semi-liquid waste. The site currently is owned by
Springfield Mobile Estates, which operated a trailer park that once consisted of 38 mobile homes.
Approximately 60 people resided in the trailer park, which was built on top of the landfill. All
residents moved as of June 1990, after selling their trailers to the parties potentially responsible
for the site contamination. Investigation of the site found volatile organic compound (VOC)
contamination in a spring and a residential well near the mobile home park. The EPA began
investigations at the site in 1976, following a resident's complaint of foul-smelling water. Three
areas of contamination have been identified at the site where industrial waste was either disposed
of separately in trenches or mixed with municipal waste. Approximately 500 people live within a
1-mile radius of the site. Many area residences are hooked up to the public drinking water
system. Residents upgradient of the site rely upon private wells for drinking water. The land use
within a 1-mile radius is primarily low-density residential housing, light agriculture, undeveloped
forest land, and commercial development. The site is on a terrace above, and 1/4 mile west of,
the Black River. Leachate from the site flows out of the side of the steep slopes next to the
landfill and eventually reaches the Black River and Seavers Brook; however, neither is used as a
drinking water source.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82

Threats and Contaminants
The groundwater, surface water, and sediments are contaminated with VOCs including
benzene and vinyl chloride. The on-site soil is contaminated with VOCs,
polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs).
On-site workers and residents are at risk by coming into direct contact with or
ingesting contaminated groundwater, surface water, soils, or sediments.
July 1995
-------
Cleanup Approach
Response Action Status
Immediate Actions: In 1984, the potentially responsible parties connected area
residents to the public water supply. In a separate action in 1987, the EPA
temporarily relocated 42 families while testing was conducted on the site. The
families were returned to their homes within a few weeks.
Leachate and Groundwater: The remedy selected by the EPA for cleanup of
leachate and groundwater includes: constructing an underground system to collect
leachate passing through the site; installing wells to extract contaminated groundwater;
treating the collected leachate and groundwater on site or possibly removing the leachate and
groundwater to a publicly owned treatment works; monitoring the site; and performing additional
studies to determine how to isolate the landfill waste materials from the groundwater. The EPA
also plans to place restrictions on future use of groundwater underlying the contaminated area.
The potentially responsible parties completed the technical specifications and design for the
selected cleanup plan in 1992. Shortly thereafter, the potentially responsible parties began
building the leachate collection, and groundwater extraction and treatment system. Construction
was completed in early 1993. The systems have been operating successfully since startup.
Routine operation and maintenance activities will be performed to ensure the continued
effectiveness of the cleanup remedy.
Source Control: The potentially responsible parties conducted additional studies to
determine alternatives for preventing waste materials from entering the groundwater.
The investigation was completed in 1990. In late 1991, the potentially responsible
parties began design of a variety of methods to control the source of site contamination. These
methods include capping Waste Areas 2, 3, and 4; collecting groundwater and surface water in
french drains; extracting groundwater in Waste Area 3 with source control wells; collecting and
venting landfill gases; stabilizing side slopes; conducting operation and maintenance activities;
limiting use of the site via institutional controls; and submitting the area to review every five
years. Construction activities were completed in the fall of 1993. The cap will be inspected
periodically and maintained to ensure its continued effectiveness.
Site Facts: An Administrative Order was issued in 1984, requiring the potentially responsible
parties to supply an alternate water supply. A second Administrative Order was issued in 1989,
requiring the parties to perform a study for a second long-term remedial phase. A partial Consent
Agreement was signed in 1990, requiring that the potentially responsible parties conduct cleanup
of the leachate and groundwater, A second partial Consent Decree was signed in 1991, requiring
that the potentially responsible parties to conduct cleanup activities to address the source of
contamination.

Site Description
The Parker Sanitary Landfill is a 25-acre site that operated as a solid waste landfill from 1972
until 1992. Before 1983, approximately 1 million gallons of liquid wastes and 760 tons of solid
or semi-solid wastes including metal plating wash waters, waste oils, electroplating sludges, paint
sludges, chlorinated solvent sludges, caustic cleaners, and metallic salts were disposed of in at
least three areas of the landfill. Liquid and sludge wastes were poured directly onto the ground or
into unlined pits and lagoons. During a site inspection in 1984, the State detected contaminants in
a stream bordering the landfill, in groundwater at the landfill, and in four private wells located
1/2 mile from the landfill. The site is located in a residential area, and an estimated 3,200 people
obtain drinking water from a municipal well field approximately 2 miles from the landfill; 124
private wells are located within 3 miles. The stream flows into the Passumpsic River, which is
used for recreational activities.

compounds (VOCs), including trichloroethylene (TCE). The site is unfenced, making
it possible to come into direct contact with hazardous substances. Trespassers or
future residents may face health threats by coming into direct contact with or ingesting
contaminated groundwater, surface water, or soil.

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: Residences with contaminated wells were hooked up to the local
public water supply.
Entire Site: Parties potentially responsible for site contamination are studying the
nature and extent of contamination at the site. The investigation is identifying
contaminants and will result in the recommendation of alternatives for final cleanup.
In 1994, EPA issued a proposed plan for cleanup of the site. The proposed plan includes capping
the landfill, including the industrial waste areas, and capturing the groundwater plume at the site
boundary, and allowing for the natural restoration of the downgradient aquifer. After reviewing
public comments on the proposed plan, expected in 1995, the EPA will evaluate the findings and
select cleanup remedies to address site contamination.
Environmental Progress
Connecting nearby residents to public water at the Parker Sanitary Landfill site has reduced
threats to public health while final cleanup activities are being planned.

PINE STREET
CANAL
VERMONT
EPA ID# VTD980523062
Site Description
EPA REGION 1
Chittenden County
Burlington
The 80-acre Pine Street Canal site consists of a portion of the Pine Street Canal, a turning basin,
an adjacent filled-in wetland, an area formerly known as Maltex Pond, and an additional portion
of land. In 1908, a coal gasification plant began operating on Pine Street, southeast of the canal.
The plant ceased operations hi 1966. Plant wastewaters and residual oil and wood chips saturated
with organic compounds were directly discharged or disposed of in the Pine Street Canal
wetland. During the 1960s and 1970s, an oil-like material was detected seeping from the wetland
into Pine Street Canal, the turning basin, and Maltex Pond. The State detected high levels of
organic compounds associated with coal tar at several locations on the site, which is located along
the proposed location for a major highway. The State is concerned that construction will release
organic compounds into the canal and possibly into Lake Champlain, the source of Burlington's
drinking water. There are several single and multiple-family dwellings, including apartment
buildings, located within a mile of the site. Burlington has a population of approximately 39,100.
Site Responsibility:
This 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
Contaminants in the groundwater include polycyclic aromatic hydrocarbons (PAHs)
and volatile organic compounds (VOCs), including benzene, toluene, and xylenes. The
sediment is contaminated with polychlorinated biphenyls (PCBs), PAHs, and VOCs.
The surface water is polluted with semi-volatile organic compounds and VOCs. The
soil contains PAHs, VOCs, and heavy metals including lead. Cyanide has also been
detected in the soil. There is unrestricted public access to the site, although access is
difficult because of the marshy terrain. Trespassers may be at risk by touching or
ingesting contaminated surface water, groundwater, soil, or sediment, or by swimming
in the canal. In addition, eating contaminated fish may pose a health hazard. Portions
of the site are seasonally flooded, permitting the spread of contamination. To inform
the public of potential health risks, the site has been posted with warning signs and no
fishing signs by the City of Burlington and the Vermont Department of Health. In
addition, wildlife at the site has been adversely affected by contaminants, especially by
the canal sediments.

Cleanup Approach
The site is being addressed in two stages: emergency actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Emergency Actions: In 1985, the EPA excavated 500 cubic yards of coal tar,
solidified it, and disposed of it in an approved facility. The Maltex Pond area also
was capped with clay, and was covered with topsoil and seeded. A temporary fence
was erected, warning signs were posted, and some sampling was conducted.
Entire Site: The EPA is currently investigating the nature and extent of site
contamination. The EPA has conducted field investigations including a soil gas
survey, a geophysical survey, air sampling, ecological studies, surface water and
sediment sampling, soil sampling, installation of monitoring wells, and groundwater sampling.
The field work was completed in early 1991. Treatability studies to aid in remedy selection were
completed in 1992. An investigation to determine cleanup alternatives was completed in late 1992
and the EPA proposed a cleanup plan. The cleanup plan was withdrawn in 1993 after the public
comment period. As a result, further studies will be undertaken prior to identifying alternative
cleanup measures and selecting final remedies.
Site Facts: In 1993, a Coordinating Council was formed to address the complex issues
regarding the cleanup of this site. The group, under the direction of a neutral facilitator, includes
EPA, the State, the potentially responsible parties, the U.S. Fish and Wildlife Service, the city,
and environmental and community groups. Working as an EPA pilot project for more effective
community involvement and alternative dispute resolution, the group has begun additional studies
to fill data gaps prior to the selection of a final cleanup remedy.
Environmental Progress
The emergency removal of coal tar, capping of the Maltex Pond area, and construction of a fence
have reduced the potential of exposure to hazardous substances, making the Pine Street Canal site
safer while further investigations are underway.

Bennington
Site Description
Tansitor Electronics, Inc. manufactures electronic capacitors and is located on approximately 36
acres in a predominantly rural area of Bennington. According to the Vermont Department of
Environmental Conservation (VT DEC), Tansitor disposed of the equivalent of 115 drums of
process wastes directly into an unnamed stream or onto the ground. An estimated 1,500 residents
of Vermont and New York obtain drinking water from private wells located within 3 miles of the
site. Runoff from the disposal area, overflow from an on-site pond, and the process wastes have
entered the perennial stream that joins Brown's Brook, which is used for recreational activities
and located 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
Final Date: 10/04/89
Threats and Contaminants
The VT DEC found that the on-site surface water, groundwater, sediment, and soils
are contaminated with silver, boron, and volatile organic compounds (VOCs). Process
wastes were found to contain the VOCs trichloroethane and acetone, oils, and acid
sludges. Due to the absence of contaminants in drinking water supplies, the site does
not pose an imminent threat to the health of the nearby population; however,
environmental damage has occurred to soils, surface water, and groundwater.
