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

Site Description
The Aberdeen Proving Ground occupies 79,000 acres of land and water near the head of the
Chesapeake Bay. The Aberdeen Proving Ground consists of two areas that are listed separately
on the NPL: the Edgewood area and the Michaelsville area. The Edgewood area comprises
13,000 acres and includes Gunpowder Neck, Pooles Island, Carroll Island, and Graces Quarters.
The two areas are separated by the Bush River. The Edgewood area was used for the
development and testing of chemical agent munitions. From 1917 to the present, the Edgewood
area conducted chemical research programs, manufactured chemical agents, and tested, stored,
and disposed of toxic materials. There are large areas of land and water and numerous buildings
that are contaminated or suspected of contamination at the Edgewood site. Virtually all the land
areas of the site reportedly are contaminated or potentially contaminated. Substances disposed of
in the area include significant quantities of napalm, white phosphorus, and chemical agents.
On-site surface waters include rivers, streams, and wetlands. There are 38,600 people living
within 3 miles of the site. On-site residences house military personnel and military dependents.
Four standby water supply wells in the Canal Creek area previously served approximately 3,000
people. The Long Bar Harbor well field of the County Department of Public Works and the well
field used by the Joppatowne Sanitary Subdistrict serve 35,000 people within 3 miles of the site.
Site Responsibility:
This site is being addressed through
Federal actions.

Threats and Contaminants
m
On-site groundwater sampling has identified various metals, phosphorus, and volatile
organic compounds (VOCs) including chloroform and benzene. On-site soil
contamination sampling has identified various VOCs, metals, and unexploded
ordnance in surface and subsurface soil. On-site surface water sampling has identified
various metals, phosphorus, and VOCs. People who accidentally ingest or come in
direct contact with contaminated groundwater, surface water, soil, or sediments may
be at risk. The wetlands area is a designated habitat for bald eagles.
Cleanup Approach
The site is being addressed in 10 stages: initial actions and nine long-term remedial phases
focusing on cleanup of the entire site, grouped here according to type of activity.
Response Action Status
Initial Actions: As an initial action, the Army conducted an environmental
monitoring program in 1977 and 1978 at the Edgewood area. Evidence of substantial
groundwater and surface water contamination was found. Contamination at the
Edgewood area has been identified in separate study areas, which will be addressed in future
long-term cleanup actions as described below. In 1991, a leaking underground storage tank was
removed from the Nike site. Other removal efforts include: testing and removing underground
storage tanks, removing contaminated soil and taking post excavation samples, and removing
surface wastes from the G-street location and transporting the wastes to an off-site disposal
facility.
O-Field: Large quantities of munitions were disposed of in various ways at O-Field's
landfill and other areas. White phosphorus, mustard gas, lewesite, and other chemical
agents have been identified as the principal contaminants. The Army selected remedies
for long-term cleanup of the landfill and affected groundwater in late 1994. The remedies include
constructing a permeable cap over the landfill, building a treatment system to address
groundwater that has become contaminated as a result of seepage from the landfill and other O-
Field areas, and continuing investigations of these other areas, including where groundwater has
contaminated sediments in nearby Watson Creek. The groundwater treatment system is designed
to contain the plume through downgradient extraction using newly installed wells. Extracted
groundwater will be treated on-site using chemical precipitation to remove inorganics, air
stripping, ultra-violet oxidation to destroy organics, followed by carbon adsorption. Treated
groundwater will be discharged to the Gunpowder River. The treatment system has been
completed and is now operational. The Army completed the technical design for the landfill cap
in early 1995 and is expecting to begin construction later this year. The Army expects to
complete the additional investigations at the O-Field area by 1997.
February 1995 2 ABERDEEN PROVING GROUND
(EDGEWOOD AREA)
-------
J-Field: Over the years, the Army has detonated munitions in trenches throughout the
J-Field. The Army is continuing investigations into the nature and extent of
contamination of J-Field, and expects to select long-term cleanup plans in early 1996.
In the meantime, the Army has undertaken erosion control efforts to prevent toxic substances
from being eroded into Chesapeake Bay. The Army began these erosion control efforts in 1994
and will continue them through 1995.
Canal Creek: Investigations along approximately 700 acres of Canal Creek are
continuing where the Army had disposed of large amounts of munitions. In mid-1994,
the Army proposed plans to control two sources of contamination. One will address
soil contamination by disposing of soils contaminated with lead and zinc into a landfill in the
area. The second will involve capping the landfill to prevent contaminants from leaching out.
Construction is expected to begin by 1996. Other studies along the Canal are continuing and are
expected to be completed by early 1996.
Carroll Island: The Army is investigating the nature and extent of contamination on
Carroll Island, where the Army had conducted open-air testing of chemical agents.
While conducting this study, the Army also has removed several structures and toxic
pits containing munitions from the Island. The Army anticipates completing the investigation and
selecting a long-term cleanup approach for this area in late 1995.
Graces Quarters: As part of its investigations into the extent of contamination of
Graces Quarters, the Army has removed munitions waste from this area. The Army is
evaluating groundwater treatment options, and is planning to perform treatability
studies over the summer of 1995. The Army expects to complete its investigations at this area in
late 1995. Based on the results of this investigation and the treatability studies, the Army will
then recommend a long-term cleanup approach.
Nike Site: The Army used the Nike Site in the early 1900s to conduct chemical
warfare training and explode munitions for testing. In 1994, the Army dismantled and
removed several anti-ballistic missile silos from this area and filled the cavities with
concrete. The Army completed investigating the extent of contamination at the Nike Site in early
1995 and expects to select a final remedy to clean up the area in mid-1995.
Bush River: The Bush River area has been used mainly for chemical storage, but
also contains a facility that has been used for handling radioactive waste material. It is
believed that many of the chemicals tested or stored in these areas have contaminated
the surrounding environment. Investigations at these areas are underway and will likely continue
through 1997. In the meantime, the Army has removed munitions from several pits and from
King's Creek, and has removed radioactive material from the 26th Street Dump for off-site
disposal.

-------
Westwood Area: The Westwood area covers approximately 523 acres and was used
as a bomb-drop test area. There is an active solid waste landfill on site which is
licensed to receive only rubble and asbestos wastes. A spill of radioactive material
occurred at the Westwood Area and reportedly was cleaned up. An investigation is underway to
define the extent of contamination at this site. The investigation is scheduled to be completed in
late 1996.
Other Edgewood Areas: This investigation includes all areas not covered by the
specific study areas mentioned above. Other study areas may be added as deemed
necessary by this investigation, which is expected to continue through 2000.
Site Facts: The Aberdeen Proving Ground 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.
Environmental Progress
The various initial actions, removal of munitions and other contaminated waste from the study
areas, and construction of the ground water treatment plant at O-Field have reduced the threat of
exposure to contaminants at the Aberdeen Proving Ground (Edgewood Area) site while final
studies and cleanup activities continue.

The Aberdeen Proving Ground occupies 79,000 acres of land and water near the head of the
Chesapeake Bay. The Michaelsville area consists of 17,000 acres, including the 20-acre
Michaelsville Landfill, the Phillips Field Disposal Area, the White Phosphorous Munition Burial
Site, and numerous known or suspected solid waste management units that may be sources of
contamination. The Michaelsville area is separated from the rest of the Aberdeen Proving Ground
by the Bush River. The area contains firing ranges, impact areas, vehicle test tracks, a fire
training area, and laboratories in support of the testing activities. The Michaelsville Landfill
operated as a sanitary landfill from the 1970s until 1980. The landfill received household garbage
and refuse from the installation. In addition, there are reports of pesticides, waste oils, paints,
solvents, and other materials having been dumped in the landfill. The landfill was originally
excavated to depths below the water table, but was later excavated to a higher depth. The Phillips
Field Disposal Area includes the active Phillips Field Landfill, Disposal Areas 1 through 4, and
two grease pits. Oil wastes suspected to include solvents and transformer oil were dumped in the
grease pits until they closed in 1980. The active Phillips Field Landfill is a construction debris
landfill and lies on top of an older landfill that is unlined and is about 16 feet deep. The White
Phosphorous Munition Burial Site is believed to be within a 15-acre area in the Chesapeake Bay
near Mosquito Creek. Allegedly, munitions were buried under 2 feet of soil at the location. The
Michaelsville area is bordered on the west by the Bush River and to the northeast and south by
the Chesapeake Bay. The area is drained by seven creeks plus the Bush River. There are 38,600
people living within 3 miles of the site. Residences located on the Michaelsville area of the site
house military personnel and dependents. Harford County and town of Aberdeen have water
supply wells on the facility, near the site boundaries.

-------
Threats and Contaminants
Preliminary groundwater and surface water sampling has identified various heavy
metals, phosphorous, and volatile organic compounds (VOCs). Soil is contaminated
with pesticides and polychlorinated biphenyls (PCBs), VOCs and petroleum
hydrocarbons. People who come in direct contact with or accidentally ingest
contaminated groundwater, surface water, soil, or sediments may be at risk. There
also is a possible risk of bioaccumulation of contaminants in the food chain.
Cleanup Approach
The site is being addressed in seven stages: initial actions and six long-term remedial phases
focusing on cleanup of Michaelsville Landfill Source Control, the Michaelsville Landfill
Groundwater, the Phillips Field Disposal Area, the Aberdeen Fire Training Area, the White
Phosphorous Underwater Munitions Burial Site, and Other Michaelsville Areas.
Response Action Status
Initial Actions: The Army excavated pesticide-contaminated soil at the golf course
and the pesticide storage building. Abandoned underground storage tanks also were
removed in accordance with an agreement with the State of Maryland. Soil sampling
around the tanks was conducted to determine if additional excavation and soil removal was
required. Visibly contaminated soil has been removed at each location and post excavation soil
samples have been taken. Wells are installed in each area where contaminated soil is left in
place. In 1991, soil contaminated with pesticides was removed from the site and again from the
golf course and incinerated at an off-site location. In 1992, soil contaminated with pesticides was
excavated from the area adjacent to the Pesticide Storage Building, and incinerated at an off-site
location. In 1993, soil from the Fire Training Area was excavated, and incinerated at an off-site
location. In 1993, a treatment plant was constructed to treat two wells in the Ferryman Wellfield
which were contaminated with VOCs.
Michaelsville Landfill Source Control: An investigation of the landfill was
completed in 1992. Based on the results of this investigation, the EPA determined that
a multi-layer cap should be constructed over the landfill. Construction of this cap was
completed in mid-1994.
Michaelsville Landfill Groundwater: An investigation into the nature and extent
of groundwater contamination at the Michaelsville Landfill is underway and scheduled
for completion in late 1995.
November 1994 2 ABERDEEN PROVING GROUND
(MICHAELSVILLE LANDFILL)
-------
Phillips Field Disposal Area: An investigation currently is underway to determine
the nature and extent of contamination in this area and the most appropriate alternative
for cleanup. This investigation is scheduled for completion in early 1995.
White Phosphorous Underwater Munitions Burial Site: This 15-acre site was
reported to have munitions buried in soil and underwater. An investigation was
completed in 1991, and it was determined that suspected contamination could not be
defined using available technology. The site is monitored after significant storm events. In 1996,
a review of new technologies to study the suspected contamination will be performed.
Aberdeen Fire Training Area: An investigation currently is underway to determine
the nature and extent of contamination at the Aberdeen Fire Training Area. This
investigation is scheduled for completion in 1994, at which time a remedy for final
cleanup will be selected.
Other Michaelsville Areas: This investigation includes all areas not included in the
other specific study areas. Identified areas include, but are not limited to, the Kirk
Incinerator, the Shell Washout Facility, settling tanks, Disposal Areas 5-11, and the
Melt Load Facility. This investigation began in 1991 and is expected to be completed in early
2002.
Site Facts: The EPA and the Army entered into an Interagency Agreement in March 1990.
Under this agreement, the Army will conduct investigations and cleanup activities at the site. The
Aberdeen Proving Ground (Michaelsville Landfill) site 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.
Environmental Progress
The removal of contaminated soil and underground storage tanks, as well as the installation of a
landfill cap and a water treatment system, have reduced immediate threats at the site while
additional studies are underway.

Site Description
The Beltsville Agricultural Research Center (BARC) covers 6,500 acres in suburban Washington,
D.C. near the northern portion of Prince George's County, Maryland. The facility, which is
owned and operated by the United States Department of Agriculture (USDA), has conducted
research on animal husbandry, dairying, and animal diseases since 1910. The site consists of
large agricultural plots and about 600 buildings, including research laboratories, administrative
offices, shops, greenhouses, barns, and several houses. To date, BARC has identified 16
separate sources of contamination; however, initial studies have only been completed on one
section of the site. This 4-acre area, known as the Biodegradable Materials Disposal Site, was
used from 1946 to the mid-to-late 1970s for disposal of metal drums, plastic containers, casings
from transformers, and laboratory wastes. Initial studies conducted by the USDA in 1990 and
1992 revealed elevated levels of poly aromatic hydrocarbons (PAHs), pesticides, poly chlorinated
biphenyls (PCBs), 1,1,1-trichloroethane, trichloroethene, xylenes, and heavy metals such as
arsenic and lead. A review of historical site data and aerial photographs has revealed an
additional 92 areas of concern that may need further investigation. A trailer park, a high school,
several housing developments, and Federal installations are located within 4 miles of the site.
Site Responsibility:
The site is being addressed through
Federal actions.

Threats and Contaminants
In 1990 and 1992, USDA analyses in 1990 and 1992 detected elevated levels of PAHs,
several pesticides, PCBs, and a variety of volatile organic compounds (VOCs) and
heavy metals in soil, ground water, surface water, and surface water sediments.
Contaminated surface water threatens several creeks and streams, such as Paint Branch,
Little Paint Branch, Beaver Dam Creek, and Indian Creek, which collect drainage from
the site. These waterways all flow into the Anacostia River, which in turn flows into
the Potomac River. Hazardous wastes from the site also threaten nearby wetlands
adjacent to Beaver Dam Creek. Fisheries in the Northeast Branch and the Anacostia
River provide a habitat for the Bald Eagle, an endangered species, and the Swamp Pink
flower, which is a threatened species.

-------
Cleanup Approach
This site is being addressed in two stages: initial actions and a long-term remedial phase
focusing on the cleanup of the entire site.
Response Action Status
Initial Actions: BARC removed the landfilled material from the Biodegradable
Materials Disposal site and backfilled the area with clean fill.
Entire Site: The EPA and BARC are currently planning site investigations to
determine the nature and extent of groundwater and surface water contamination.
Upon completion of this investigation, final cleanup remedies will be selected.
Environmental Progress
The removal of landfilled material and backfilling the area with clean fill have helped make the
site safer while investigations of the Beltsville Agricultural Research Center (USDA) are being
planned.

Harris Landfill
Site Description
The Bush Valley Landfill site is an unlined, 29-acre, former municipal solid waste landfill located
in Harford County. Prior to 1974, the site was used for grazing cattle and raising crops. In
1974, a local family leased the site area, and in late 1974 or 1975, began operating the property
as a landfill. The landfill was permitted by the State of Maryland in August 1975. From 1975
through 1978, several inspections performed by the Harford County Health Department and the
State noted a number of permit violations in the operation of the landfill. From 1978 through
1982, the State issued orders to the owner to bring the site into compliance with established
cleanup standards; however, the owner never fully complied with the orders. The site received
cover material in 1983 when the landfill operation was abandoned. During investigations
conducted by EPA and Harford County, several leachate seeps were observed on the slopes of
the landfill and groundwater in the vicinity of the site is contaminated. A few private wells are
located nearby on properties adjacent to the site but all residents in the area have been connected
to a public water system for their drinking water supply. The site is bordered to the north by a
wooded flood plain, to the east by a tidal marsh which is part of the Bush Declaration Natural
Resources Management Area, to the south by woods, and to the west by Bush Road.
Groundwater generally flows west to east beneath the landfill. Bynum Run Creek is located
approximately 300 feet to the north of the site. The Bush River Tributary is located
approximately 1,500 feet to the east of the site.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.

Threats and Contaminants
Volatile organic contaminants (VOCs) including benzene, vinyl chloride and
tetrachloroethene, and metals including beryllium, arsenic, and manganese have been
detected in ground water, surface water, soil, and leachate samples. VOCs have been
detected in air samples. The Human Health Risk Assessment performed by the EPA
from 1993 to 1994 indicates that groundwater is the primary source of risk to people;
however, no residents are currently using the groundwater in the area for their water
supply. Additionally, inhaling contaminated air poses a risk to human health. The
contaminants in the leachate seeps and the marsh area east of the site threaten
ecological resources in the area.
Cleanup Approach
This site is being addressed in a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status
Entire Site: In 1992, the parties potentially responsible for site contamination began
conducting an investigation to determine the nature and extent of contamination. This
investigation is scheduled to be completed in 1995. Upon completion, final cleanup
remedies will be selected.
Site Facts: An Administrative Order was issued on December 21, 1990, requiring the
potentially responsible parties to conduct an investigation. In 1994, the EPA prepared a Human
Risk Assessment and an Ecological Risk Assessment at the site to determine whether
contamination posed a threat to human health or the environment.
Environmental Progress
After listing this site on the NPL, the EPA performed a preliminary investigation and determined
that the Bush Valley Landfill site does not pose an immediate threat to nearby residents or the
surrounding environment while investigations are underway and cleanup activities are being
planned.

Contaminants detected in the air, soil, and surface water included cyanides, ammonia
compounds, acids, caustics, and heavy metal salts. Health threats at the site included
coming into direct contact with contaminated air, surface water, and soils; breathing
contaminated air; and ingesting contaminated surface water or accidentally ingesting
contaminated soils. Danger of fire and explosion from volatized chemicals on the site
posed an additional threat to nearby residents.
July 1995
-------
Cleanup Approach
Response Action Status
Entire Site: All materials posing an immediate threat at the site were identified,
removed, and disposed of in 1982. Drums, scrap debris, and liquid organic waste
were removed. Liquid inorganic wastes were treated to make them acceptable for
discharge into the city sewer system. The underground storage tank at the former gas station was
filled with concrete slurry. A clay cap and topsoil were applied and compacted over the site.
Sand blasters removed chemical contamination from the walls of the former gas station. The
interior of the laboratory and manufacturing area were cleaned and decontaminated. The site was
fenced and police and fire personnel were made available to ensure site security. As a result of
the cleanup activities and subsequent sampling to ensure the effectiveness of the remedy, the
EPA, in cooperation with the State of Maryland, determined that the site no longer posed a threat
to the public. The site was deleted from the NPL in 1982.
Site Facts: The Chemical Metals Industries site was placed on the Interim Priorities List in
October 1981. All cleanup actions were completed before the first proposed NPL was
established.
Environmental Progress
In conjunction with the State, the EPA has determined that the Chemical Metals Industries site
has been cleaned to established standards and is no longer a threat to the public or the

This site is being addressed through a
combination of Federal, State and
potentially responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/01/84

Threats and Contaminants
The groundwater beneath and in the vicinity of the site is contaminated with volatile
organic compounds (VOCs) including trichloroethene, 1,2,-dichloroethene, vinyl
chloride and benzene, and metals including cadmium, lead and mercury, as a result of
former waste disposal practices. Contaminants detected in soils include VOCs,
polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAHs),
phthalates, and lead. Past health threats included coming into direct contact with
contaminated soil and inhaling contaminated air. Potential health threats include
exposure to contaminated groundwater if used as a drinking water supply.
Cleanup Approach
This site is being addressed in three stages: emergency actions and two long-term remedial
phases focusing on source control and cleanup of contaminated groundwater.
August 1995
-------
Response Action Status
Emergency Actions: In 1984, EPA removed approximately 1,200 drums from the
site. The majority of drums contained flammable solids; an additional drum
contained PCBs. The site was covered with 12,000 cubic yards of topsoil, and
surface contours were reshaped to prevent surface water from mixing with contaminants and
moving off site. EPA also installed a fence for security purposes and to prevent public access.
Source Control: In 1987, EPA selected a remedy to control the source of
groundwater contamination and to reduce the potential for exposure to contaminated
soils. The remedy includes a subsurface slurry wall that encircles the waste disposal
area, a multi-layer cap, a de-watering system, and continued groundwater monitoring.
Construction of the remedy was completed in 1990.
Groundwater: Potentially responsible parties are conducting an investigation to
determine the nature and extent of groundwater contamination coming from the site
and additional land immediately north of the site. This investigation will identify
alternatives for cleanup and is scheduled to be completed in 1997.
Site Facts: In 1983, the State of Maryland ordered the potentially responsible parties to
conduct cleanup activities. The parties appealed the order, and the State requested EPA's
assistance in cleaning up the site. In 1992, EPA issued a Unilateral Administrative Order to the
site owners. The Order restricts uses of the site that would disturb the integrity of the source
control remedy. In 1993, EPA and four potentially responsible parties signed an Administrative
Order on Consent under which the potentially responsible parties agreed to conduct an
investigation into the nature and extent of groundwater contamination under EPA supervision.
Environmental Progress
Removal of wastes, capping of contaminated soils, and installation of fencing has reduced the
potential for exposure to contamination at the Kane and Lombard Street Drums site. Source
control measures, completed in 1990 eliminated the risk associated with exposure to contaminated
soils and controlled the movement of contaminants into groundwater. Alternatives for cleaning
up contaminated groundwater will be identified as a result of ongoing studies.

cleanup.
August 1995
-------
Response Action Status
Entire Site: EPA has selected the following remedies for cleanup of the soil:
reshaping site surface contours to control water runoff; capping contaminated soil on
the properties; and fencing both properties. Construction of the cap began in 1994
and is expected to be completed in 1995.
Groundwater: An initial investigation of groundwater contamination began in 1987.
In 1992, the potentially responsible parties began a supplemental investigation into the
nature and extent of groundwater contamination. The investigation is expected to be
completed in 1995, at which time cleanup alternatives will be identified and a final cleanup
remedy will be selected.
Site Facts: The potentially responsible parties entered into a Consent Decree with EPA and the
State to conduct cleanup activities at the site in December 1989. Also, the potentially responsible
parties agreed to supply drinking water to several residents whose wells are contaminated and to
monitor all residential wells for contamination.
Environmental Progress
Capping the Diggs and Cumberland Cement properties, providing drinking water to affected
residents, and performing continuous monitoring of residential wells has reduced the threat of
exposure to contaminated groundwater at the Limestone Road site while final cleanup activities

EPA REGION 3
Anne Arundel County
Harmans
Site Description
The 3-acre Mid-Atlantic Wood Preservers, Inc. site was an active wood-treating facility in
Harmans until 1993. The site consists of two parcels that straddle Shipley Avenue near its
intersection with Dorsey Road. Both parcels are enclosed by chain-link fencing. The operation
employed a two-part process to preserve the wood with chromated copper arsenate (CCA). In
the first part, workers would pressure-treat lumber with CCA solution in a housed processing
plant; in the second, the wood was allowed to drip and dry. Analyses conducted by the
Maryland Department of the Environment (MDE) in 1978 revealed that the groundwater beneath
and downgradient from the site was contaminated with chromium. The contamination was
determined to have originated from two sources: overflow from a CCA preservative storage tank
and drippings from the wood drying area. Based on these findings, MDE issued an order
requiring Mid-Atlantic Wood Preservers to remove 26 cubic yards of highly contaminated soil
beneath the CCA storage tank's overflow pipe. Although the actions were taken in compliance
with the State's order to improve the quality of the groundwater, residual contamination
remained. In 1993, the owner of the facility discontinued preserving operations on the site. The
Stoney Run creek flows north through a wetland area 600 feet west of the site, extending
approximately 4 miles before discharging into the Patapsco River near Elkridge. Surface water
from the site drains toward Stoney Run, which is used for recreational purposes. The area
surrounding the site is industrial, commercial, and residential. The closest residence is located
within 200 feet of the site.

Threats and Contaminants
m
Groundwater beneath and downgradient of the site was contaminated with arsenic and
chromium from a 1978 spill of CCA solution; recent sampling shows no remaining
health risks due to that release. Heavy metals including arsenic and chromium from
former process wastes are present at elevated concentrations in the surface soils on
site. People were at risk if they accidentally ingested or inhaled dust from
contaminated soils. The site has been paved with asphalt to prevent the threat of
direct contact. The wetlands and stream areas near the site are not contaminated, but
were potentially subject to surface water run off from the site.
August 1995
-------
Cleanup Approach
Response Action Status
Immediate Actions: Under State orders in 1980, the owner developed plans to
address the groundwater contamination. Operational changes included leaving the
drying wood on the concrete drainage pad longer before moving it to the storage lot
and modifying the drainage pad so that it collected all waste drippings for reuse. All wastes
captured by the drip pad were recirculated within the process system, and sludges were shipped
off site for disposal. The owner also removed 26 cubic yards of contaminated soil from beneath
the chemical storage tank overflow pipe and disposed of it at a federally approved facility.
Surface Soils: An investigation into the nature and extent of groundwater and soil
contamination at the site was completed in 1990 by the site owner. In 1990, remedies
were selected for site cleanup, including capping of arsenic-contaminated soils hi areas
where the concentrations exceed 10 mg/kg, environmental monitoring, and deed restrictions.
Design activities and construction of the remedy were completed by the potentially responsible
party in 1993, under EPA oversight.
Site Facts: The owner/operator of the facility was implementing the cleanup remedy in
accordance with a Unilateral Order until June 1993, when the owner/operator notified EPA of his
inability to finance the remaining construction activities. Gunther's Transport, an adjacent
landowner and prospective purchaser of the property decided to finance the construction efforts at
its own risk as a gesture of good-faith. The primary component of the selected remedy included
paving the facility with asphalt. In January 1994, EPA finalized a prospective purchaser
agreement with Gunther's Transport. Inc. in which the government agreed not to sue for past
costs incurred by EPA under the former owner. In return, Gunther's Transport, Inc. agreed to
contribute $10,000 toward the Agency's past costs, complete the construction of the remedy, and
perform operation and maintenance and periodic reviews. Gunther's Transport, Inc. now uses
the 3-acre parcel for company parking. Land-use restrictions are in place.
Environmental Progress
All construction at the site is complete. Removing contaminated soil and paving the site with
asphalt to prevent the threat of direct contact with surface soils has reduced site contamination to
safe levels.

Threats and Contaminants
Wastes located on site were contaminated with paint sludges, solvents, and heavy
metals. Some drums were crushed, ruptured, or deteriorating. Soil was contaminated
with heavy metals such as lead, aluminum, chromium, zinc, cyanide, barium, and
cadmium. Because access to the site was unrestricted, direct contact with contaminated
soil was possible; however, no contamination remains on site today.
August 1 995
-------
Cleanup Approach
Response Action Status
Emergency Actions: In 1983, EPA conducted an emergency cleanup to eliminate
immediate threats from contamination. EPA performed the following tasks: removed
contaminated soil and 5-gallon pails of marine paint; sampled the soil to confirm that
contaminant removal had been adequate; installed six groundwater monitoring wells around the
site perimeter; sampled and tested drums; and moved 1 million tires elsewhere on the site to
expedite subsurface investigation. More drums were discovered under the tires. The EPA later
removed 68 drums, 70 contaminated tires, and 610 tons of contaminated soil.
Entire Site: The EPA and the State conducted an intensive investigation of site
conditions during and after the emergency removal. The study evaluated groundwater,
surface water, soil, air quality, and sediment quality in the vicinity of the site. It
revealed that, as a result of the previous EPA cleanup actions, the hazardous wastes had been
eliminated, and no threat to public health or the environment remained. The site contains only
uncontaminated trash and debris. Declaring that no further cleanup action was warranted, EPA,
with agreement from the State, deleted the site from the NPL in April 1988. In 1993, EPA
conducted a site visit and a review of the file to evaluate whether the site remains safe. The
State also collected groundwater samples. Pursuant to this review, EPA recommended that the
State resample the wells on site, abandon several wells which are no longer useable, and
investigate the continued use of the site as a dump. The State has agreed to implement these
recommendations.
Environmental Progress
Through emergency removal of hazardous wastes and evaluations of the extent of contamination
at the Middletown Dump, EPA successfully cleaned up the site. After further studies, EPA, with
concurrence by the State, determined that the site no longer posed a threat to the surrounding
community or the environment, and deleted the site from the NPL in 1988.

Site Description
Ordnance Products, Inc. (OPI) is a 95-acre site located in a rural area, adjacent to the Little
Northeast Creek, 2 miles northeast of the Town of North East in Maryland. In 1960, OPI
purchased the property and began ordnance manufacturing. During the 1960s, the facility
manufactured grenade fuses, detonation devices, and smoke grenades, among other ordnance.
Some off-specification ordnance was burned in open pits or buried on site. The wastewater
resulting from the manufacturing operations was disposed of in five unlined surface enclosures.
Ordnance manufacturing at the site ceased in 1972, and OPI closed the facility. In 1986,
Mechanics Valley Trade Center (MVTC) the site and planned to develop it as an industrial park.
MVTC and the site have since been sold, but retained the MVTC corporate entity; currently,
they are renting several buildings in a secure portion of the site. In 1987, the Maryland
Department of the Environment (MDE) discovered the site while investigating a property nearby.
MDE conducted extensive site sampling and determined that there were elevated levels of heavy
metals such as arsenic, selenium, and barium in site soils, groundwater, and surface water.
MDE also discovered volatile organic compounds (VOCs) such as trichloroethene,
tetrachloroethene, vinyl chloride, and xylene in two on-site wells and four off-site residential
wells. One of the on-site wells is currently connected to an on-site air stripping tower. In 1988,
in accordance with an EPA-issued Unilateral Administrative Order, Kraus Design, Inc. (KDI),
the holding company of OPI, began site investigations. Their results indicated several sources of
contamination, including drums scattered over the site, five surface enclosures reportedly used for
disposal of plating and other waste, three subsurface disposal areas containing discarded
ordnance, three burn areas also containing ordnance, and other areas of contaminated soil.

The Patuxent River Naval Air Station is a 6,400-acre facility located at the confluence of the
Patuxent River and the Chesapeake Bay on a peninsula known as Cedar Point. Most of the
peninsula is woods or wetlands. Surface water on Cedar Point is contaminated as a result of the
operations of three known landfills—the Fishing Point Landfill, the Former Sanitary Landfill, and
the Current Sanitary Landfill—and from a portion of the site known as the Pesticide Control
Rinse Area. From 1960 to 1974, the Fishing Point Landfill received solid and hazardous wastes
such as sewage treatment plant sludge, cesspool wastes, spent oil absorbents, paints, antifreeze,
solvents, thinners, pesticides, and photolab wastes. In 1974, the Navy began depositing these
wastes in the Former Sanitary Landfill and, in 1980, began using the Current Sanitary Landfill,
which remains in operation today. Combined, the Former and Current Sanitary Landfills cover
approximately 16 1/2 acres. Before the Navy established the landfills, it disposed of hazardous
substances in the surrounding wetlands. The Pesticide Control Shop Rinse Area has generated
300 to 400 gallons of rinsate per day since 1962. Two fishing areas on the site, Pond 3 and Pine
Hill run, are located in the surface water pathway of the Pesticide Control Shop Rinse Area and
the Former and Current landfills. Pine Hill Run empties into the Chesapeake Bay. The State of
Maryland has issued a fish advisory for the ponds on the base. The town of Lexington Park

Threats and Contaminants
The shallow groundwater contains heavy metals including cadmium and chromium,
volatile organic compounds (VOCs) including benzene and toluene from former waste
disposal practices, and semi-volatile organic compounds. Heavy metals, pesticides,
and VOCs have been detected in sediments and surface water. Soil is contaminated
with VOCs. Accidental ingestion of shallow, on-site groundwater poses a risk to those
who drink it. Trespassers are at risk by coming into direct contact with, inhaling, or
accidentally ingesting contaminated soils. Site access is restricted by a fence around
the perimeter of the facility. Fish samples taken downstream from the site show no
sign of being contaminated.
Cleanup Approach
The site is being addressed in four stages: immediate actions and three long-term remedial actions
focusing on cleanup of the shallow aquifer, monitoring of the deep aquifers, and cleanup of
on-site soil.
July 1995
-------
Response Action Status
Immediate Actions: Under State order, the owner removed 200,000 gallons of
liquid waste from the site in 1974. In 1985, a temporary fence was constructed
around on-site ponds and seeps to limit access to these contaminated areas.
Drums and Shallow Aquifer: In 1983, the EPA began an investigation into the
nature and extent of contamination of the shallow aquifer. The contamination resulted
from drums stored on site. Based on the results of the study, the EPA issued a
statement in 1985 outlining a long-term cleanup approach. The selected cleanup actions include
pumping and treating shallow groundwater, fencing the site to restrict access, and excavating and
disposing of drums of hazardous materials. Site fencing was completed in 1989. Drum removal
activities were completed in early 1991. The groundwater treatment system is currently under
construction.
Deep Aquifers: In 1986, the potentially responsible parties began an intensive study
to determine the nature and extent of deep aquifer contamination and to identify
alternatives for cleanup. The remedy selected by the EPA calls for on-site and off-
site groundwater monitoring and on-site and/or off-site point-of-use treatment for the
contaminated groundwater, as necessary. Currently, the parties are conducting groundwater
monitoring under EPA oversight.
On-Site Soils: There are several pits of buried hazardous material which may serve
as a source for groundwater contamination. The EPA has decided to excavate and
dispose of the contents of one pit of highly contaminated material and to investigate
two additional pits. Investigations will be completed in 1995, at which time the EPA will
determine the final cleanup approach for on-site soils.
Site Facts: In 1986, a group of potentially responsible parties signed a Consent Agreement with
the EPA under which they agreed to perform investigations at the site. Forty-one potentially
responsible parties and the EPA signed a Consent Decree in November 1987, in which the parties
agreed to conduct cleanup actions and to pay for a portion of the EPA's past and future oversight
costs. This Decree was amended in April 1991 to include monitoring and cleanup, if necessary,
of the deep aquifers. The EPA expects to offer the potentially responsible parties the opportunity
to conduct actions to address the hazardous wastes buried in on-site pits, as well.
Environmental Progress
The construction of a fence around the site to limit public access, the removal of liquid wastes,
and the excavation and removal of buried drums have reduced the potential for direct contact
with hazardous materials at the Sand, Gravel, and Stone site. The planned excavation of a buried
pit will further reduce the threat to human health posed by the site.

WOOD TREATING
MARYLAND
EPA ID# MDD980704852
Site Description
The Southern Maryland Wood Treating (SMWT) site is an inactive wood treating facility located
approximately 50 miles southeast of Washington, DC near Hollywood, Maryland. From 1965
until 1978, 25 acres of the 96-acre property were used during wood treatment operations. Both
creosote and pentachlorophenol (PCP) were used to treat wood at the site. Process wastewater
was piped into six unlined lagoons located near the process buildings. In 1982, the State of
Maryland ordered the site owner to clean up the site by spraying water from the lagoons on a
wooded portion of the site, and by land farming the lagoon sludge on a 3-acre field previously
used to store untreated wood. The landfarming was performed improperly, and shallow soil in
that section of the site remains highly contaminated. Other areas of the site were contaminated
by drippings from treated wood, or by spills of wood treating chemicals. The land near the
SMWT site is mainly forest and fields. Fewer than 125 residences are located within a 1/2 mile
radius of the site. Residents rely on groundwater as a source of drinking water; however,
residential wells located downgradient of the site have not been found to be contaminated.

Threats and Contaminants
Proposed Date: 10/15/84
Final Date: 06/10/86
The shallow on-site groundwater in the former lagoon area is contaminated with
volatile organic compounds (VOCs), PCP, and polynuclear aromatic hydrocarbons
(PAHs), which are constituents of creosote. Shallow soil in the land farming area and
deep soil in the former lagoon area is also highly contaminated. The primary threats
to the public include long-term exposure to shallow soil and ingestion of shallow
groundwater from the former lagoon area.

-------
Cleanup Approach
This site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on cleanup of the entire site and remaining areas.
Response Action Status
Initial Actions: In 1982, under state order, the site operators attempted to clean up
the site by spray irrigating the lagoon liquid onto a wooded area of the site and
landfarming sludge from the lagoons onto an area formerly used to store untreated
lumber. The lagoons were emptied, filled with clean fill, and graded. The excavated sludge was
layered with wood chips from a sewage treatment operation and covered with soil. During a
1985 site assessment, the EPA discovered sludge-like materials seeping into an on-site fresh
water pond. In late 1985 and early 1986, 1,400 cubic yards of contaminated sediment and soil
were dredged from the pond area, stabilized with cement kiln dust, and stored inside
impermeable synthetic materials. In 1993, the EPA undertook additional actions to further
stabilize the site. These actions included: off-site disposal of products left in tanks and retorts;
off-site disposal of highly contaminated soil contained in several on-site tanks; disposal of drums
of investigation- derived waste; installation of an under flow dam to prevent the release of
floating and sinking materials from an on-site pond; and demolition of on-site buildings in danger
of collapse. In addition, a trench was installed between the on-site pond and the former lagoon
area in an attempt to intercept dense non-aqueous phase liquids (DNAPLs) migrating toward the
pond. A water treatment system, which will treat contaminated groundwater from the pond and
the trench, is under construction and is expected to be completed in 1995.
Entire Site: In 1988, the EPA selected a remedy for the site which included: on-site
thermal treatment of contaminated soil, sediment, and liquids remaining in abandoned
process tanks; on-site treatment of water using carbon adsorption or chemical
treatment; and construction of a barrier wall to reduce the potential of off-site migration of
contaminants during site cleanup. To reduce the threat of off-site migration of contaminated
groundwater, the EPA constructed the barrier wall of interlocking steel sheet piles in 1990. All
cleanup actions were completed in 1991. No further action is planned for these areas.
Remaining Areas: The EPA, in conjunction with the State, undertook a Focused
Feasibility Study (FFS) in mid-1992 to re-evaluate a limited range of site cleanup
options. A plan identifying cleanup alternatives is scheduled to be released in 1995,
with the final cleanup remedy slated to be selected later in the year.
Site Facts: In mid-1992, the State of Maryland informed the EPA that it could not fund its
share of the cost of cleanup. Under the Superfund law, for federally funded site cleanups, states
must pay ten percent of the cost of the cleanup.

Environmental Progress
By excavating and stabilizing contaminated freshwater pond sludge, removing buildings, drums,
and various wastes, and by installing a sheet pile barrier wall around the groundwater
contamination plume, the EPA has prevented the further spread of contaminants while remaining
activities are being planned.

Cecil County
Elkton
Site Description
The Spectron, Inc. site is approximately 8 acres and located in Elkton, a primarily rural area.
From the 1800s until 1946, several paper manufacturers occupied the site. In 1961, Galaxy
Chemicals, Inc. took over the site, using it to recover organic solvents from wastes generated by
the electronics, pharmaceutical, paint, lacquer, coatings, and chemical process industries. Galaxy
Chemicals went bankrupt in 1975 and the facility was taken over by Solvent Distillers, Inc. in
1976. Solvent Distillers, Inc., which changed its name to Spectron, Inc. in 1978, closed the
facility in 1988 as a result of actions taken by various county, State, and Federal agencies; it
currently is in bankruptcy proceedings. Over the years, several lagoons were used at the site to
recover wastes. Approximately 1,500 drums were found in a former evaporation lagoon during a
joint investigation conducted by the EPA and the Maryland Water Resources Administration; 500
of these drums were damaged, rusting, open, and leaking. In mid-1969, a sludge pit that had
been filled with solid residues was discovered adjacent to the lagoon. Nearby residents
repeatedly complained about the odors emanating from the lagoon and sludge pit. Investigators
also reported that finding between 50 and 73 tanks holding 582,000 gallons of hazardous
substances, including chlorinated solvents, other organic compounds, and heavy metals. Little
Elk Creek and Elk River are used for recreational fishing; the State has designated these bodies
of surface water for protection and maintenance of aquatic life. Approximately 5,200 people
obtain their drinking water from private wells located within 4 miles of the site; the nearest
private wells are located within several hundred feet of the site. Well waters are also consumed
by livestock.
Site Responsibility:
The site is being addressed through
Federal, State, local, and potentially
responsible parties' actions.

Threats and Contaminants
Sampling of leachate seeps discharging into Little Elk Creek indicate elevated levels of
chlorinated solvents and volatile organic compounds (VOCs). Similar contaminants
have been detected hi samples of the water downstream from the site. On-site
monitoring wells are also contaminated with VOCs. The wetlands by the creek are
potentially threatened by polluted air migrating from the site. Touching or ingesting
contaminated surface water, groundwater, or soil and breathing contaminated air may
pose a health risk. Wetlands near Little Elk Creek are located within 15 miles of the
site and are potentially threatened by air pollution.
Cleanup Approach
This site is being addressed hi two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: In mid-1989, the EPA and the potentially responsible parties
removed and disposed of wastes and cleaned the tanks, berms, and dikes. In 1991,
these parties fixed dikes around the tanks and overpacked leaking drums to control
the release of hazardous substances from seeps and groundwater entering Little Elk Creek.
Entire Site: An investigation into the nature and extent of groundwater
contamination began in 1990. Upon completion of the investigation, EPA will select
a final cleanup remedy for the remainder of the site.
Site Facts: EPA has issued several Administrative Orders on Consent (AOCs) to the parties
potentially responsible for site contamination. The first of these orders resulted hi the initial
actions taken hi 1989. The EPA ensured that the potentially responsible parties had the
opportunity to remove site contaminants by negotiating a second AOC hi mid-1990. A third
AOC, negotiated hi 1991, resulted hi additional removal actions undertaken by the potentially
responsible parties. Spectron, Inc. is currently hi bankruptcy procedures.

Environmental Progress
By removing and disposing of hazardous substances and stabilizing site conditions, the EPA and
the potentially responsible parties have reduced the immediate threats posed to the nearby
population and environment while additional investigations at the Spectron, Inc. site are
underway.

EPA ID# MDD980504344
EPA REGION 3
Cecil County
Woodlawn
Other Names:
dlawn Transfer Station
Site Description
Cecil County owned and operated the 37-acre Woodlawn County Landfill from 1965 to 1979,
when it was closed under a State order. Before becoming a landfill, the property was a privately
owned sand and gravel quarry. Operators filled two large quarry pits with agricultural,
municipal, and industrial wastes. According to State records, the only documented hazardous
waste disposal at the site was polyvinyl chloride (PVC) sludge from the Firestone Tire and
Rubber Company (now Bridgestone/Firestone, Inc.). This sludge initially was disposed of
throughout the site, but between 1978 and 1981 three designated disposal cells were put into use.
Analyses by the EPA, State, and parties potentially responsible for site contamination found
contamination in on-site groundwater as well as in stream sediments near the site. An estimated
5,700 people draw drinking water from public and private wells located within 3 miles of the
site. The nearest private well is located within 400 feet of the landfill. All homeowners adjacent
to the site use private wells as their sole source of water. Samples obtained from 13 domestic
wells surrounding the site were found to be free of site-related contamination at levels of
concern. However, recent sampling has indicated the presence of vinyl chloride in one private
well. The contaminated stream enters Basin Run, a State-designated trout stream, located
approximately 2 miles from the site.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 01/22/87
Final Date: 07/22/87
Threats and Contaminants
The groundwater is contaminated with volatile organic compounds (VOCs), including
vinyl chloride, benzene, and toluene; pthalates; polynuclear aromatics hydrocarbons
(PAHs); and heavy metals including manganese, lead, cadmium, and arsenic. VOCs
and heavy metals are found in stream sediments. Vinyl chloride has been detected in
on-site sludge. Potential health threats include accidentally ingesting or coming into
direct contact with contaminated groundwater or sludge.
August 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: The parties potentially responsible for the contamination
capped the PVC sludge in 1981 to keep rainwater from spreading pollutants, and
installed monitoring wells. The State samples on-site monitoring wells twice a year.
In addition, a carbon water treatment system was installed at the one residential well where vinyl
chloride was detected.
Entire Site: The potentially responsible parties agreed to undertake an intensive
study of soil and groundwater contamination at the site and to recommend the best
cleanup alternatives. Prior to the beginning of the investigation, 20 monitoring wells
were installed by Cecil County and the State. Twelve additional wells were installed during the
investigation. The investigation began in 1988 and was completed in 1993, at which time the
EPA selected a final cleanup remedy. The remedy includes excavating and disposing of the soils
from the former drain field of the transfer station septic system; relocating the current drain field
of the transfer station septic system; capping of the landfill; extracting and treating on-site
groundwater, with discharge to an on-site stream; groundwater, surface water, and landfill gas
monitoring; providing an alternate water supply, if necessary; deed restrictions; and perimeter
fencing. Design activities are expected to be completed in early 1997.
Site Facts: The EPA signed a Consent Order in 1988 with the Firestone Tire and Rubber
Company (now Bridgestone/Firestone, Inc.) and Cecil County to conduct an investigation of site
contamination.
Environmental Progress
Capping the PVC sludge has eliminated the possibility of rainwater spreading the contaminants
from the Woodlawn County Landfill, and installing a carbon water treatment system at one
residential well has eliminated exposure to contaminated drinking water of one affected residence
while final cleanup activities are being planned.
