Silvestri Bros. Landfill
Johnston Site
Site Description
The Central Landfill site covers approximately 154 acres of a 600-acre tract in Johnston. This
active landfill is owned and operated by the Rhode Island Solid Waste Management Corporation
and receives approximately 85 percent of Rhode Island's solid waste. The site comprises two
areas, a 121-acre area and a 33-acre expansion area. The 121-acre area was used prior to 1980
for the disposal of municipal and hazardous waste. Between 1980 and 1983, only municipal waste
was disposed of here. The 33-acre area is currently being used to dispose of municipal solid
waste. Located within the 121-acre area is an approximately 1/2- acre area where about 1 1/2
million gallons of hazardous wastes were disposed of between 1976 and 1979. Within this 1/2
acre hazardous waste area, bulk liquid waste was dumped into trenches that had previously been
excavated to bedrock. The wastes disposed of in this area include latex waste, acid waste,
corrosive waste, water soluble oils and waste solvents, including methylene chloride, toluene,
1,1,1-trichlorethane and tetrachloroethylene. In 1982, the owner complied with a State order to
close the areas that had received hazardous material. These areas have been excavated,
backfilled, and capped to prevent further contamination of the groundwater and surface water,
and revegetated as part of the closure plan. Approximately 4,000 people live within 3 miles of
the site; the nearest resident is 1/2 mile away. Private wells downgradient from the site may have
been contaminated. The bedrock aquifer has been contaminated, and adjacent wetlands and
surface waters have also been affected. Cedar Swamp Brook, used for recreational boating, flows
southeast along the southwest perimeter of the site.
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) such as
benzene, chlorobenzene, toluene, vinyl chloride, methyl ethyl ketone, bis(2-
ethylhexyl)phthalate, and 1,2-dichlorobenzene, and metals including arsenic,
beryllium, cadmium, lead, manganese, and vanadium. Adjacent surface waters,
sediments, and wetlands have also been affected by the contamination. The EPA has
determined that the public is not at immediate risk from site contamination; however,
potentially affected residents are being supplied with a public drinking water supply.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on the cleanup of on-site and off-site contamination.
Response Action Status
Initial Actions: A landfill gas collection and combustion system, which is used to
generate electricity, has been built, as well as public water supply lines in the area of
Central Landfill. The current owner also purchased all residential land within 1,000
feet of the landfill, and has offered to purchase all residential property up to 2,000 feet from
landfill.
On-Site Contamination: In 1987, the owner/operator began an investigation to
determine the nature and extent site contamination and to determine alternatives for
cleanup. The study identified sources of contamination and, in the summer of 1994,
final cleanup remedies were selected. The remedies include capping the landfill, extracting and
treating groundwater in the most highly contaminated 11/2 acre of the site, establishing
institutional controls, and conducting a detailed evaluation of the existing landfill gas collection
and combustion system.
Off-Site Contamination: In 1994, the owner/operator began an investigation to
address the cleanup of off-site contaminated groundwater. The first phase will
address the cleanup and control of sources of contamination. The second phase will
address the cleanup of off-site contaminated groundwater, surface water, and sediments. Final
cleanup remedies are scheduled to be selected in early 1996.
Site Facts: In 1987, the owner of the landfill entered into a Consent Order with the EPA to
conduct a study of contamination at the site.
Environmental Progress
The installation of the landfill gas collection and combustion system and public water lines, and
the purchase of residential property around the landfill have reduced the threat of health risks to
the public while studies at the Central Landfill are being conducted and the final cleanup
remedies are being planned.

Glocester/Smithfield
Site Description
The Davis (GSR) Landfill is a 58-acre site that includes a 21-acre inactive landfill located in the
Towns of Glocester and Smithfield. Between 1974 and 1976, the landfill, which was privately
owned and licensed by the State to accept municipal wastes, accepted wastes from Glocester,
Smithfield, Warwick, and Providence. In 1978, the State declined to renew the landfill license
because the facility had violated numerous rules and regulations for operating solid waste
management facilities. Numerous legal actions to close the site ensued, and the State Supreme
Court ruled in favor of the State in 1982, at which time the site became inactive. However, the
landfill was never properly capped or stabilized. The State found both surface water and
groundwater contamination on site. Approximately 200 residents who use private water wells
live within a 1-mile radius; there are approximately 4,700 people within a 3-mile radius using
private wells.
Site Responsibility:
This site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 04/10/85
Final Date: 06/10/86
Threats and Contaminants
On-site groundwater, surface water, and sediments are contaminated with volatile
organic compounds (VOCs), such as vinyl chloride and benzene, polycyclic aromatic
hydrocarbons (PAHs), and heavy metals including manganese, arsenic, and lead.
Surface water and sediments are contaminated with the pesticides chlordane and DDT.
These pesticides pose a potential threat to plants and wildlife at the site. Access to the
site is limited by a locked gate on the access road. Direct contact with or accidental
ingestion of, contaminated on-site surface water, sediment, or groundwater may have
adverse health effects.
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: In 1990, the EPA began an investigation into the nature and extent of
contamination at the site. Completion of the investigation is scheduled for early 1996,
at which time the EPA will select a final cleanup remedy.
Environmental Progress
In 1990, the EPA conducted tests of site conditions and determined that the Davis Landfill poses
no immediate threat to the public or the environment while further investigations are taking place.

RHODE ISLAND
EPA ID# RID980523070
Site Description
EPA REGION 1
Providence County
Smithfield
The Davis Liquid Waste site is a disposal facility for hazardous wastes that covers approximately
10 acres and is located in a rural section of Smithfield. Throughout the 1970s, the site accepted
liquid and chemical wastes such as paint and metal sludges, oily wastes, solvents, acids, caustics,
pesticides, phenols, halogens, metals, fly ash, and laboratory Pharmaceuticals. Liquid wastes
were transported in drums and bulk tank trucks and were dumped directly into unlined lagoons
and seepage pits. The operator periodically excavated the semi-solid lagoon materials, dumped
them at several locations on the site, and covered them with soil. Other operations included the
collection of junked vehicles and machine parts, metal recycling, and tire shredding. These
activities resulted in soil, surface water, sediment, and groundwater contamination, both on and
off site. In 1978, discovery of off-site well contamination prompted the State Superior Court to
prohibit further dumping of hazardous substances on the Davis property. The owner is still using
sections of the disposal area and a 20-acre adjacent property as a staging and storage area for 10
to 30 million tires. The area is residential and the closest homes are located within 1,500 feet of
the site. There are 240 people living within 1 mile and 4,700 people living within 3 miles of the
site. The nearest well is 300 feet away. The property is bordered on the north and south by
wetlands and swamp areas.
Site Responsibility:
The site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Threats and Contaminants
Groundwater contamination consists of volatile organic compounds (VOCs) and heavy
metals including arsenic and lead from the lagoons and seepage pit areas. The soil,
lagoon sediments, and surface water also are contaminated with VOCs and heavy
metals. Residential wells to the north and northeast of the site are contaminated with
VOCs. People could be exposed to contaminants by ingesting contaminated
groundwater, coming into contact with contaminated soils on site, or by inhaling
chemicals that evaporate from the soil or surface water. Because the bordering
wetlands have been filled with tires and waste material, water elevations have
increased, resulting in a large area of stressed wetland vegetation.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on provision of a new water supply line and cleanup of the entire site.
Response Action Status
Initial Actions: From 1985 to 1986, the EPA sampled, packed, and staged
approximately 600 intact and crushed drums and shipped them off site for approved
disposal. At the same time, bottled water for drinking and cooking was supplied by
the Rhode Island Department of Environmental Management to residences with contaminated
wells. This temporary action provided a safe water supply while a permanent remedy was being
investigated.
Water Supply Line: A new water distribution system will serve 120 lots along
Forge Road, Log Road, Burlingame Road, and Bayberry Road. The new system
includes construction of a 300,000-gallon water storage tank, a water main, pumping
stations, and connections to existing residences. For undeveloped lots, the EPA will bring a
service connection up to the property line so that future connection may take place at the owner's
expense. Installation of the water storage tank and water line piping to residents in the vicinity of
the site has been completed. Construction of the remaining parts of the system, including pump
stations, is under way. All construction activities are planned for completion in 1996.
Entire Site: The final cleanup remedy calls for excavating 25,000 cubic yards of
raw waste and contaminated soils for on-site incineration, and treating on-site
groundwater using an air stripper, followed by carbon filtration to remove the
contaminants from the air. In addition, incinerated soil will be tested and clean soil will be used
to backfill the area; the rest will be placed in an EPA-approved landfill located at the site. The
groundwater extraction and treatment component of the remedy is in the process of being
designed. Design activities are expected to be completed in late 1995. The design of the soil
cleanup component of the remedy will be initiated once the groundwater treatment plant is
operational and functioning. Soil cleanup work is expected to begin in 1997. The EPA expects
soil cleanup to be completed in two years, and groundwater cleanup to take 5 to 10 years.
Site Facts: Discovery of off-site well contamination in 1978 resulted in the State Superior Court
banning dumping on the site. The EPA obtained a Court Order to gain access to the site. The
Department of Justice prepared a motion for a "conditional" site access to be entered in the
Rhode Island Federal Court. The site owner resisted attempts by Federal officials to investigate
the site for cleanup and continued to conduct business operations within 100 feet of the hazardous
dumping site. The State of Rhode Island has recently entered into an agreement with the site
owner for the removal of between 10 and 30 million tires currently being stored at the site.

DOD/NCBC/Allens Harbor Landfill
Site Description
The Davisville Naval Construction Battalion Center (NCBC), located 18 miles south of
Providence in North Kingstown, covers approximately 1,500 acres. Serving as a military
installation since 1951, its primary mission is to provide mobilization support to Naval
construction forces. Much of the NCBC-Davisville site is contiguous with Narragansett Bay and
consists of three areas, including the Main Center, the West Davisville storage area, and Camp
Fogarty, a training facility 4 miles west of the Main Center in the Town of East Greenwich.
Adjoining NCBC's south boundary is the decommissioned Naval Air Station Quonset Point,
which was given to the Rhode Island Port Authority in 1973. The Navy disposed of wastes hi all
four areas. The Navy has identified at least 24 areas with potential hazardous contamination, but
the Department no longer owns several of them. These areas are being investigated by the Army
Corps of Engineers; chief among the areas is the Camp Avenue Landfill at the decommissioned
Naval Air Station. The Navy's studies will focus on ten areas: the Allen Harbor Landfill (the
largest of the areas), which received solvents, paint thinners, degreasers, polychlormated
biphenyls (PCBs) from transformers, sewage sludge, and contaminated fuel oil from 1946 to
1972; the Calf Pasture Point, which received "decontamination agents" and various other
contaminants; the Construction Equipment Department (CED) Battery Acid Disposal Area; the
CED Solvent Disposal Area; the Transformer Oil Disposal Area (near Building 37); the Solvent
Disposal Area; the Defense Property Disposal Office (DPDO) Film Processing Disposal Area
(FPD); the Camp Fogarty Disposal Area; the Fire Fighting Training Area; and the Disposal
Areas northwest of Buildings W-3, W-4 and T-l. Approximately twenty 5-gallon cans of calcium
hypochlorite were disposed of in a drainage ditch at Calf Pasture Point between 1960 and 1971.
In 1973, thirty to forty 35-gallon cardboard containers of a chloride compound were stored at the
site and deteriorated over time. From 1968 to 1974, approximately 2,500 3-gallon cans also were
disposed of at Calf Pasture Point. From 1968 to 1974, the Transformer Oil Disposal Area may
have received 30 gallons of PCB-containing oil, which was drained from transformers and poured
onto the ground east of Building 37. The surrounding area is single-family residential.
Approximately 27,000 people get their drinking water from public wells located within 3 miles of
the site.

Threats and Contaminants
Proposed Date: 07/14/89
Final Date: 11/21/89
Heavy metals including lead, cadmium, silver, mercury, and chromium were found in
the sediments and on the shoreline of Allen Harbor. Other contaminants in Allen
Harbor include poly cyclic aromatic hydrocarbons (PAHs), polynuclear aromatic
hydrocarbons (PNAs), solvents, and PCBs. Soil contamination is not specified, but
dumping practices involved organic solvents, PCBs, sewage sludge, contaminated fuel
oil, and halogens. Some public wells are located between 1 and 3 miles upgradient
from disposal sites. The potential of contamination from these wells is small.
Groundwater is shallow, 2 to 4 feet in some areas, and the soil is permeable,
conditions that facilitate movement of contaminants into the groundwater. In addition,
it has been shown that Allen Harbor is polluted. A number of salt marshes that could
be affected by contamination from the site have been identified in the Allen Harbor,
Calf Pasture Point, and Narragansett Bay areas.
Cleanup Approach
The site is being addressed in five stages: initial actions and four long-term remedial phases
focusing on cleanup of Buildings 316 and 38, the Allen Harbor Landfill, the DPDO/FPD and
Transformer Oil Disposal Area, and other areas of the site.
Response Action Status
Initial Actions: In 1991, the Navy removed materials from two on-site buildings
that were contaminated by PCB spills. An additional excavation is being planned to
address the removal of the remaining PCB-contaminated materials that were not
removed during the initial phase. Throughout 1995, the EPA plans to remove PCB-contaminated
soil at the disposal areas northwest of Buildings W-3, W-4, and T-l, remove the battery acid
tank at the CED Battery Acid Disposal Area, remove the asphaltic material at the CED Asphalt
disposal area, and remove lead from contaminated soil at Camp Fogarty.
Buildings 316 and 38: In 1991, the Navy removed flooring materials and
underlying soils from Building 316, the DPDO Transformer Oil Spill Area and
Building 38, and Transformer Oil Leak Area. Additional sampling after removal
operations revealed elevated levels of PCBs outside the excavated areas. A long-term remedy
was selected in the fall of 1993 calling for the excavation and off-site disposal of remaining PCB-
contaminated materials at a federally licensed disposal facility. Design for the long-term remedy
was completed in 1994 and construction activities began in 1995.
July 1995 2 DAVISVILLE NAVAL CONSTRUCTION
BATTALION CENTER
-------
Allen Harbor Landfill: In 1985, the water, sediment, and organisms in Allen Harbor
were sampled as part of the confirmation studies and found to be contaminated. Given
the landfill's location adjacent to the harbor, it is possible that leachate could migrate
into the harbor. An investigation into the nature and extent of site contamination and assessment
of possible cleanup alternatives is scheduled for completion in late 1995.
DPDO/FPD and Transformer Oil Disposal Area: The Navy took 16 soil samples
from the Transformer Oil Disposal Area in 1985 and six samples in 1986 and
analyzed them for PCBs. An additional investigation into the nature and extent of site
contamination and assessment of possible cleanup alternatives is scheduled for completion in
1995. The potential for contaminants to migrate off site is moderate to high. Groundwater is
assumed to flow toward Hall Creek, which is located 600 feet from the site.
Other Areas: Investigations into the nature and extent of contamination at eight
additional areas identified by the Navy are scheduled for completion in 1997. These
areas include the CED Battery Disposal Area, CED Solvent Disposal Area, Calf
Pasture Point, Camp Fogarty Disposal Area, Fire Fighting Training Area, and the Disposal Area
northwest of buildings W-3, W-4 and T-l. A magnetometer study was conducted at the Calf
Pasture Point area to locate the cans containing contaminants. Soil borings were taken in 1985 to
determine the depth of contamination. The mobility of contaminants is moderate to high;
however, the effect on the groundwater to date has been minimal.
Site Facts: NCBC 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. In 1988,
the EPA and the Naval Ocean Systems Center began conducting a study at the Allen Harbor
Landfill under a Memorandum of Agreement.
Environmental Progress
A remedy was selected in 1993 to address PCB contamination at Buildings 316 and 38. Removal
of contamination throughout the site began hi 1995. In the meantime, the Navy has performed
preliminary investigations and has determined that there are no immediate threats to human health
or the environment while additional site studies are taking place.

mile east of Slatersville Reservoir
in North Smithfield
Site Description
The Landfill and Resource Recovery, Inc. (L&RR) site is a 28-acre landfill on a 36-acre parcel
of land. The site originally was a sand and gravel pit and was used for small-scale refuse disposal
from 1927 to 1974. In 1974, the site was sold and developed into a large-scale disposal facility
accepting commercial, municipal, and industrial wastes. Until 1979, an estimated \lh million
gallons of hazardous wastes were accepted and disposed of with other wastes in the central
portion of the landfill. The hazardous wastes included many types of bulk and drummed organic
and inorganic materials in liquid, sludge, and solid forms. In 1979, the operator placed a
polyvinyl chloride cover over the area containing hazardous waste to prevent rainwater from
entering. Landfilling of commercial and residential wastes continued until 1985, when the owners
closed the landfill and placed another synthetic cover over most of the landfill. Soil was placed
over the synthetic cover and it was partially planted with vegetation. Although the area is still
rural, there are approximately 10,000 residents in a 25-square-mile area; the area appears to be
undergoing a substantial growth in residential development. Within a 1/2-mile radius of the site,
there are fewer than 50 residences and no multi-residential housing developments. More than
3,000 people live within 3 miles of the site. An industrial park is located approximately 3,000
feet to the north, and Air National Guard installations are approximately 1,000 feet to the east
and 3,000 feet to the south of the site. Most, if not all, residences in the site's vicinity obtain
their drinking water from individual wells. Trout Brook, adjacent to the site, and the Slatersville
Reservoir, into which it discharges, are used for fishing and other recreation, but are not public
water supply sources.

Threats and Contaminants
The air at the landfill is contaminated with volatile organic compounds (VOCs)
including carbon tetrachloride, chloroform, and benzene. The on-site groundwater is
contaminated with arsenic, lead, and VOCs from waste liquids disposed of on site and
from rainwater entering the landfilled wastes and causing contamination to move into
the groundwater. The surface water on the site is contaminated with lead. The only
health threat is from gaseous emissions from the landfill. The landfill is enclosed by a
single-strand fence. As a part of the ongoing construction activities, a chain link fence
was constructed in the fall of 1994 to limit access to the site. The only significant
environmental threat is to the wetlands surrounding the site. The wetlands are being
affected by sand eroding from the landfill. The eroded sand is not contaminated;
however, it is filling in the wetlands, destroying vegetation and decreasing the ability
of the wetland area to support plant and animal life.
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 1977, the owner installed monitoring wells on site to ensure
compliance with State regulations. The owner closed the landfill in 1985, and 3/4 of
the site was covered with a synthetic cap to minimize infiltration of rain and melted
snow. Soil also was used to establish a vegetative cover. The cap was designed and built with gas
vents to prevent the buildup of gases under the cap. These vents currently are sealed. The
selected long-term remedy for this site includes: installation of more substantial fencing;
stabilization of the steep side slopes of the landfill and installation of a synthetic cap over the
uncapped area of the landfill, with establishment of a vegetative cover over the entire landfill;
collection and thermal destruction of underlying gases; and groundwater and air monitoring.
Design of these cleanup actions by the potentially responsible parties was completed in 1994
under EPA oversight. Cleanup activities are currently underway.
Site Facts: In 1985, the landfill was closed by the owner under a Consent Order with the State.
In 1990, the EPA issued an Administrative Order to the potentially responsible parties to conduct
the design and implementation of cleanup activities.
Environmental Progress
Partially closing the landfill, installing a cover, and building a fence to limit access to the site
have reduced the potential for exposure to hazardous materials at the Landfill and Resource
Recovery site while final cleanup activities are underway.

Site Description
The 1,063-acre Newport Naval Education and Training Center (NETC) site has been used by the
Navy as a refueling depot since 1900. An 11 1/2-acre portion of the site along the shore of
Narragansett Bay, known as McAllister Point Landfill, accepted wastes consisting primarily of
domestic refuse, acids, solvents, paint, waste oil, and oil contaminated with poly chlorinated
biphenyls (PCBs) from 1955 to the mid-1970s. Three tank farms are located in the Melville
area; one is located in Midway. Sludge from nearby tank farms was dumped on the ground or
burned in chambers. Other contaminated areas on site, such as the Melville North Landfill, are
classified as Formerly Used Defense sites and are being addressed separately. Surface water and
ground water flow from the landfill into the bay, which is used for boating and fishing. One tank
farm is 300 feet from a coastal wetland. Other areas of concern include Old Fire Fighting
Training Area/Site 09, Tank Farm Four/Site 12, and Tank Farm Five/Site 13. An estimated
4,800 people obtain drinking water and 220 acres of land are irrigated from private wells within
3 miles of hazardous substances at the site. Approximately 10,000 people live within 3 miles of
the site.

Threats and Contaminants
Monitoring wells detected petroleum products and heavy metals, including lead in the
ground water. Groundwater also is contaminated with volatile organic compounds
(VOCs), PCBs, and petroleum hydrocarbons. Landfill soil and leachate contain heavy
metals, petroleum hydrocarbons, and PCBs. Initial studies have shown that none of
the areas on site pose an immediate threat to public health. However, the site warrants
a study to assess potential long-term impacts. The tidal action of the Narragansett Bay
may spread contamination to the shore, marine environment, and nearby wetlands. A
sediment sampling program is underway to determine the impact.
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 McAllister Point Landfill, Tank Farms, and the remaining site areas.
Response Action Status
Initial Actions: A 1991 investigation revealed elevated levels of petroleum
hydrocarbons in soils. This study led to the removal of the contents of tanks 53 and
56. These tanks are being closed pursuant to the State of Rhode Island's underground
storage requirements. Another action is scheduled to remove known soil contamination and to
address groundwater contamination around the tanks.
McAllister Point Landfill: A remedy was selected in 1993 that called for capping of
the landfill. This will emiminate the infiltration of rainfall through waste materials
and reduce the generation of leachate released to the near shore marine environment.
This source control remedy also required a series of additional investigations designed to
determine if the landfill gases will require treatment, determine if additional measures are
necessary to address the lateral flow of groundwater, delineate near-shore contamination of the
sediments, and determine whether Non-Aqueous Phase Liquids (NAPLs) are present. Design of
the remedy was completed in 1994. Construction of the cleanup remedy is currently underway
and scheduled to be completed in 1996.
Tank Farms: An investigation into the nature and extent of site contamination was
completed in 1992. An interim remedy for the management of contaminated
groundwater originating from Tank Farm 5 was selected in 1992. A groundwater
pump and treat system has been installed to eliminate the flow of contaminated groundwater from
the source area soils to the waters of the adjacent Narragansett Bay. Additional investigations are
scheduled that will further define the extent of contamination associated with the ruins,
characterize the sludge material in the oil/water separator, confirm the contamination levels in on-
site groundwater, and determine the significance of inorganic contaminant levels in soil and
groundwater.
Remaining Site Areas: Investigations of contamination at the remaining site areas
are underway, including the former Fire Fighting Training Area, the Coddington
Cove Rubble Fill, the Naval Undersea Warfare Center, and the Gould Island
Electroplating Shop. These studies will identify the source and extent of soil and groundwater
contamination.
Site Facts: This site is being addressed under 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.

Other Names:
Blackstone Valley
Site Description
The Peterson/Puritan, Inc., site is located along the Blackstone River within the Towns of
Cumberland and Lincoln. The site is about two miles long and extends approximately 2,000 feet
to the east and west of the main river channel. The Peterson/Puritan, Inc. plant was built in
1959 and began packaging aerosol consumer products. In 1976, following a major fire, the plant
was rebuilt. The site "study area" comprises an industrial park, including the former
Peterson/Puritan facility, an inactive landfill known as JM Mills Landfill, an inactive solid waste
transfer station, sand and gravel operations, Rhode Island State Park development, affected
municipal water supply wells and numerous interspersed areas of undeveloped land along the
Blackstone River. The Martin Street well and Lenox Street well in the Town of Cumberland and
the Quinnville well field in the Town of Lincoln were closed due to contamination, and remain
out of service. Attempts to flush contaminants from the Lincoln wells were abandoned after
repeated efforts to remove the contaminants failed. The Peterson/Puritan, Inc., site is located in
a mixed industrial and residential area. There are approximately 12,000 people living within a
4-mile radius of the site; the nearest residence is less than 1/4 mile away. Approximately 17,000
people were served by the Lenox Street well prior to its closure due to contamination. The
Town of Lincoln has since been connected to an alternate water supply while the Town of
Cumberland absorbed the cost of its wells by increasing production from remaining town water
supplies.

Threats and Contaminants
Groundwater is contaminated with chlorinated solvents, volatile organic compounds
(VOCs) including acetone and benzene; phthalates; and heavy metals such as
chromium, lead, and mercury. Certain soil sample locations are contaminated with
polychlorinated biphenyls (PCBs). Surface water is contaminated with low
concentrations of VOCs. People are at risk if they come into direct contact with or
accidentally ingest contaminated ground water, surface water, sediment, leachate, or
potentially contaminated soil. The site is located in a flood plain, which may cause
water, sediments, plants, and animals to become contaminated.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on cleanup of the primary source area and the JM Mills Landfill.
Response Action Status
Initial Actions: In 1992, a fence was constructed to restrict access to the JM Mills
landfill and drums containing contaminated materials were removed from the base of
the landfill.
Primary Source Area: Parties potentially responsible for site contamination
completed investigating the full extent of contamination in 1993. In late 1993, after
evaluating cleanup alternatives, the EPA selected remedies to address the primary
sources of contamination at two areas: the CCL-Area and the PAC-Area. The remedy for the
CCL-Area includes using soil vapor extraction technology to clean soils surrounding a tank farm,
pumping and treating a contaminated groundwater plume emanating from the tank farm, and
pumping groundwater downgradient from the tank farm to the local sewer system. The leach
fields will be excavated in the PAC-Area and in-place oxidation will be used to reduce arsenic
concentrations in groundwater. The EPA also will monitor contaminant levels in groundwater to
ensure that the cleanup efforts are effective. Technical design activities are underway and
construction is expected to begin shortly.
JM Mills Landfill: An investigation into the nature and extent of contamination at
the landfill is scheduled to begin in late 1996. Following the completion of this study,
a final cleanup remedy will be selected.
Site Facts: After a preliminary investigation in 1982, the EPA identified the Peterson/Puritan
facility as the major source of the contamination in the Quinnville Well Field. The Town of
Lincoln filed a lawsuit against Peterson/Puritan, Inc. based on these findings. In 1984, the
company reached a settlement with Lincoln and assisted with the cost of the town's new water
supply. The company also installed a recovery well on its property for the purpose of capturing
contaminated groundwater underlying its property. In 1987, an Administrative Order was issued
to Peterson/Puritan, Inc. to take over the site investigation from the EPA.
Environmental Progress
Alternative water supplies have provided safe drinking water to affected area residents, and
access to the landfill has been restricted. EPA has completed its investigation of the source
control and selected a final cleanup remedy.

Site Description
The Picillo Farm site is a portion of a former 100-acre pig farm. More than 10,000 drums of
hazardous waste and an undetermined bulk volume of liquid chemicals were disposed of into
several unlined trenches on an 8-acre area of the farm. The site was discovered in 1977, when a
fire and explosion occurred. After requiring the property owners to halt the illegal disposal
operations, the State of Rhode Island conducted an emergency removal of drums containing
sodium aluminum hydride. From 1980 through 1982, the Rhode Island Department of
Environmental Management and the EPA excavated the trenches and removed the majority of the
wastes. The contaminated soil was stored on site in three piles. These piles were moved off site
in 1988. More than 2,000 people live within 3 miles of the site. There are 50 residences located
within a mile of the site; two are within 1A mile. All residences rely on private wells for their
water; these wells are sampled approximately once a year by the Rhode Island Department of
Health. The site lies near the upper Roaring Brook watershed, which is a tributary to the Moosup
River. Groundwater and surface water runoff flows away from the disposal site toward an
unnamed swamp, Great Cedar Swamp, and Whitford Pond, which is used to irrigate a cranberry
bog.

Threats and Contaminants
On-site groundwater is contaminated with VOCs including toluene and xylene and
semi-volatile organic compounds (SVOCs). Off-site groundwater and surface water in
the swamp is contaminated with VOCs and SVOCs. On-site soil is contaminated with
phenols, polychlorinated biphenyls (PCBs), and VOCs. Potential threats include use of
groundwater and surface water as drinking water supplies and direct contact with
contaminated soil. Contaminated surface water and surface soil may pose ecological
risks.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: emergency actions and two long-term remedial phases
focusing on controlling the source of the contamination and cleanup of groundwater and surface
water.
Response Action Status
Emergency Actions: From 1980 to 1982, the EPA and the State removed 10,000
buried drums from five trenches on site; bulk wastes were also removed.
Contaminated soils were dug from trenches and were stockpiled on site.
Source Control: The remedy selected by the EPA and performed by the parties
potentially responsible for site contamination included: disposal of 3,500 cubic yards
of PCB-contaminated soils and 3,000 cubic yards of phenol-contaminated soils in an
approved, off-site landfill; installation of a fence; installation of a surface drainage control
system; and closure of the site. These remedies were completed in 1988. The Rhode Island
Department of Health samples private wells in the vicinity approximately once a year. The Rhode
Island Department of Environmental Management is responsible for operation and maintenance of
the cleanup remedies.
Groundwater and Surface Water: The EPA completed the study of on- and
off-site groundwater and surface water contamination, as well as residual soil
contamination. The investigation defined the nature and extent of contamination, and
performed human and ecological risk assessments. The field investigation was completed in 1992
and final cleanup remedies were selected in 1993. The selected remedies consist of in-place
enhanced soil vapor extraction and treatment of VOCs and SVOCs in contaminated soil, off-site
disposal of the surface soil contaminated with PCBs, and extraction and treatment of
contaminated groundwater. Design of the cleanup remedies began in early 1995 and is expected
to be completed in 1996.
Site Facts: In 1988, the EPA entered into an agreement with 12 potentially responsible parties.
Four of these companies removed approximately 6,500 cubic yards of contaminated soils and
closed and vegetated the site under monitoring by the EPA.
Environmental Progress
Removal of the contaminated soil from the trenches has reduced the potential for accidental
contact or exposure to contaminated soil and dust and addressed the source of groundwater
contamination. Removal of buried drums and closure of the site has reduced the potential of
exposure to site contaminants while remedies to clean up the groundwater and surface water are
being designed.

Rose Hill Road
Site Description
The Rose Hill Regional Landfill site is a former municipal landfill located in the Town of South
Kingstown. The Town leased the land for a domestic and industrial waste disposal facility, which
operated from 1967 to 1983. In 1983, the facility became inactive, and the operator graded and
seeded the disposal areas. A transfer station for municipal waste, currently owned and operated
by the Town, is located on a portion of the site. Three separate areas on the site received waste:
a solid waste landfill, a bulky waste disposal area, and a sewage sludge landfill. Current owner-
operated activities within the site's boundary include a hunting preserve, field skeet range,
qualifying range, kennel and field training of bird dogs, and a pet cemetery. An estimated 17,300
people obtain water from wells located within 3 miles of the site. The area is both rural and
residential, with forested areas, fields, small farms and sand/gravel mining activities nearby. The
site is bordered by the Saugatucket River to the east, and Mitchell Brook flows through the site.
Site Responsibility:
This 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
On-site groundwater monitoring wells contain several volatile organic compounds
(VOCs) including 1,1 dichloethane, chloroethane, vinyl chloride, benzene, and
xylenes, as well as some heavy metals. Observations indicate that Mitchell Brook, an
unnamed brook, and the Saugatucket River could be affected by contaminated runoff
from the site. Three private wells adjacent to the site are contaminated with low levels
of organic compounds, as are on-site soils. The site is not completely fenced, making
it possible for people to come into direct contact with hazardous substances.
Saugatucket Pond, 2,000 feet downstream, is used for fishing and swimming. A
freshwater wetland is 500 feet downstream and also could be subject to contamination.
June 1995
-------
Cleanup Approach —
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: In 1985, the Town of South Kingstown Utilities Department
extended the municipal water line to residences on Rose Hill Road with contaminated
wells. EPA investigations during the winter and spring of 1993 indicated gas
migration from the landfill to nearby residences. In response to this information, the Town of
South Kingstown installed gas alarms in the residences and relocated one residence.
Entire Site: EPA began its investigation into the nature and extent of contamination
in the three separate disposal areas in 1990. The scope of the investigation included
sampling of groundwater, surface water, soils, and sediments. Expanded studies
included an ecological impact assessment, and a landfill gas migration evaluation. The EPA will
evaluate cleanup alternatives during 1995 and following a public comment period will select a
cleanup remedy for the site.
Environmental Progress
The Town of South Kingstown has provided a safe drinking water supply to residents who could
potentially be affected by contaminants migrating from the site. EPA has investigated landfill gas
migration from the site to nearby residences and the Town of South Kingstown has taken action
to control the threat to the public. The EPA will continue to assess conditions at the Rose Hill
Regional Landfill site as the evaluation of cleanup alternatives progresses.

Site Description
Stamina Mills, which is on a 5-acre parcel of land, began operating as a textile mill in the early
1900s. It was closed for an undetermined period of time during the Depression and changed
ownership in the 1940s. In 1969, a solvent scouring system for removing oil and dirt from newly
woven fabric was installed. Some time during that year, a trichloroethylene (TCE) spill occurred
and was never cleaned up. In 1975, the mill was closed. In 1977, a fire destroyed the
manufacturing complex; the site has been vacant and unused since then. In 1981, in response to
the discovery of private well contamination, the Rhode Island Water Resources Board and the
Town of North Smithfield installed a public water line to area residences; however, not all
residences were connected to the service. The EPA later provided resources to extend the water
system and complete connections to those residences. By 1987, all residences were connected to
the public water supply. The Village of Forestdale, with a population of approximately 1,000, is
located within a Va-mile of the site. A school and private residences with nearly 300 people are
within !4 mile of the site. Industrial and commercial facilities with about 1,200 people are within

dieldrin, and polycyclic aromatic hydrocarbons (PAHs). The soil is contaminated with
TCE, dieldrin, and heavy metals including lead, arsenic, and cadmium, as well as
PAHs. Surface water is contaminated primarily with VOCs. People who trespass on
the site potentially are at risk from direct contact with contaminated soils, surface
water, or groundwater. In 1986, a security fence was erected to prevent unauthorized
entry into the site.
July 1995
-------
Cleanup Approach
This 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 1981, the Rhode Island Water Resources Board and the
Town of North Smithfield installed a public water line to area residences and
provided bottled water to those residences that were not connected to the services. In
1984, the EPA provided resources for extending the public water system and connecting
additional residences to the system. By 1987, all residences were connected to the public water
supply. In 1986, the EPA also installed a fence to prevent entry to the site. In 1988, the EPA
removed two tanks from the site, pumped the waste from the tanks, and sent it to an approved
hazardous waste facility. In 1990, the EPA removed the contents of an aboveground storage tank,
decontaminated the tank shell, and disposed of the tank contents at an EPA-approved hazardous
waste facility.
Entire Site: Based on its investigation, the EPA selected the following remedy to
clean up the site: in-place vacuum extraction of soil contaminated with TCE in the
spill area, which involves installation of a number of shallow wells to withdraw air
containing TCE and other VOCs for carbon treatment; excavation of approximately 550 cubic
yards of landfill waste and sediments in the 100-year flood plain; and redepositing excavated
landfill waste under a new multi-layer cap. Ground water will be extracted and treated with
ultraviolet light and hydrogen peroxide, an innovative technology, to remove VOCs. Mill
raceways will be sealed, and on-site buildings will be demolished. Deed restrictions will be used
at the site to regulate land use and preserve the integrity of the remedy's components. The septic
tank location will be confirmed and its contents tested and removed. The contents of the tank and
the tank itself will be disposed of. A monitoring program for the groundwater, soil, surface
water, and sediments will be implemented to ensure the effectiveness of the selected remedy.
Demolition activities were completed in the summer of 1992. At this time, partially standing
structures were demolished, debris and building rubble were sorted and disposed of, voids were
collapsed and filled in, the two raceways were sealed, and a majority of the site was graded and
covered with clean fill. Quarterly groundwater sampling activities were initiated at the site in
November 1992. The results of quarterly groundwater monitoring will be used to establish a
baseline of information prior to the design and construction of the groundwater extraction and
treatment system. Pre-design field work is underway, including the operation of a pilot-scale soil
vapor extraction and groundwater UV/Hydrogen Peroxide System. The technical design of the
remaining portions of the cleanup remedy is scheduled for completion in early 1996.
Site Facts: In 1991, an Administrative Order was issued by the EPA to the operator of the site
to perform the cleanup of the site. To date, the operator has been in compliance with the
requirements of the order.

Environmental Progress
The initial actions of providing a public water supply and fencing the site have reduced the
potential for exposure to the contamination at the Stamina Mills site. A deteriorating tank
containing low pH hazardous substances was removed and properly disposed of. Some drums and
underground tanks have been removed from the site, further reducing the potential for exposure
to contamination. In the summer of 1992 the buildings and demolition debris were removed from
the site and the site was graded in preparation for the design and construction of the soil vapor
extraction and groundwater treatment systems. These actions have reduced site risks while
construction of the final site remedies is underway.

Site Description
This site consists of two adjacent properties, the West Kingston Town Dump and the University
of Rhode Island (URI) Disposal Area. Known in the past as "South Kingstown Landfill #2," the
61/2 acre West Kingston Town Dump received solid waste from the Town of South Kingstown
beginning in the 1930s. In the early 1950s, the Town of Narragansett and URI also began
disposing of their solid waste in the landfill. This disposal of solid waste went unregulated until
1967, when the Rhode Island Department of Health (RI DOH) noted during a site inspection that
wastes disposed of at the site were from industrial, residential, commercial, and institutional
sources. Numerous operational violations were subsequently cited by RI DOH. A 1975 study
conducted by the URI Department of Civil Engineering and the Rhode Island Water Resources
Board resulted in the discovery of a leachate plume beneath the landfill which was contaminating
ground water as far as 1,200 feet west of the dump. From 1945 to 1987, solid waste was also
accepted at the 12-acre URI Disposal Area, referred to in the past as the "URI Gravel Bank" or
the "Sherman Farm." After closure of the town dump hi 1978, the URI Disposal Area began
accepting most of URI's waste, including small quantities of empty paint cans, oil containers, and
pesticide containers. Lab equipment, machinery, closed drums, and old tanks buried on site were
discovered by the Rhode Island Department of Environmental Management (RI DEM) during a
1987 inspection. RI DEM instructed URI to remove contaminated debris from the site, an action
which was completed by URI in 1987. Vehicle access to the site is restricted by a locked chain-
link gate across the gravel access road at its intersection with Plains Road. An estimated 15,800
people obtain their drinking water supply from three major public wells located within 4 miles of
the site. An additional 12,000 persons are supplied by private wells, the nearest being
approximately 1,000 feet northwest of the site. Three private wells, approximately 875 feet west
of the site, were closed in 1988 due to contamination. The site is located within the Chipuxet
River valley basin. Hundred Acre Pond, part of the river, is approximately 1,500 feet from the
site. The river basin is a major groundwater resource.

Immediate Actions: In 1987, URI removed 159 tons of materials and transported
them to regulated waste disposal facilities. Removal investigations of the site were
performed in mid-1992 and the fall of 1993. These investigations indicated that the
site does not pose an immediate threat to human health or the environment.
Entire Site: An investigation to determine the extent of contamination at the entire
site is planned to begin in mid-1996.

Burrillville, adjacent to Douglas Pike
Western Sand & Gravel, a 20-acre site located in a rural residential area of Burrillville, was a
sand and gravel quarry operation from 1953 until 1975. The quarrying operation continues today.
From 1975 to April 1979, approximately 12 acres of the 20-acre site were used for the disposal
of liquid wastes, including chemicals and septic waste. Over time, the wastes penetrated into the
permeable soil and contaminated the groundwater. Contents of tank trucks were emptied directly
into 12 open lagoons and pits, none of which were lined with protective materials. The pits were
concentrated on a hill that slopes to Tarkiln Brook, which is used for recreational purposes and
drains into the Slaterville Reservoir. The State closed the disposal operation because nearby
residents complained of odors. Approximately 600 people within a 1-mile radius of the site
depend on groundwater. Eight homes were found to have contaminated wells.

Cleanup Approach
Response Action Status
Initial Actions: In early 1980, the State began to pump one lagoon dry to halt
leachate movement. Approximately 60,000 gallons of liquid chemical and septic
waste were removed for off-site disposal. A groundwater recirculation system was
installed.
Water Line: The EPA built a permanent alternate water supply to service
approximately 56 parcels of land. The potentially responsible parties installed carbon
canister filters as a temporary protective measure in all the homes in the affected area
until the permanent water supply was functional. Construction of the permanent water line was
completed in 1992.
Soil Capping: In 1988, the parties potentially responsible for contamination installed
a 2!/2-acre cap over the areas of contaminated soil and sludge and graded the site to
promote runoff and drainage. The site was also fenced and the potentially responsible
parties agreed to maintain the fence, cap, and site. All construction is complete.
Groundwater: The potentially responsible parties conducted an investigation to
determine the extent of contamination and to evaluate alternatives for cleanup of the
off-site groundwater. The investigation was completed in early 1991. Based on the
investigation, the EPA selected a remedy of cleanup through natural attenuation. The site will be
monitored through 1995. At that time, a system to pump and treat the groundwater will be
installed if monitoring shows that natural cleanup is not occurring as predicted. If natural cleanup
is working as expected, the potentially responsible parties will monitor groundwater and conduct
evaluations every three years, with EPA oversight.
Site Facts: Approximately 45 potentially responsible parties entered into a Consent Decree with
the EPA and agreed to pay for past costs, to build a cap, to conduct an investigation to determine
the nature and extent of contamination, and to identify alternatives for cleanup of contaminated
groundwater. The parties also agreed to pay the EPA for the cost of construction of the alternate
water supply system.
Environmental Progress
Construction of all cleanup activities are complete, including fencing, capping, and grading the
contaminated areas of the Western Sand & Gravel site, installing carbon canister filters, installing
an alternative water supply system, and installation and monitoring of a groundwater monitoring
network. Stabilizing the site and providing an alternate water supply system are keeping the site
safe while natural processes clean the groundwater.
