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

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

Site Description
The Taputimu Farm is owned by the Government of American Samoa and was the Territory's
primary repository of unused and outdated agricultural chemicals and pesticides. The farm
consists of a three-room farm warehouse and a trailer. The pesticide materials were stored on a
concrete or steel floor of the storage areas and trailer. Ten drums and leaking and deteriorating
containers were found improperly stored within the facility buildings. The facility is located
approximately 1/4 mile from a public beach. Approximately 3,000 people depend on groundwater
within a 3-mile radius of the site for domestic purposes.
Site Responsibility:
This site was addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Deleted Date: 03/07/86
Threats and Contaminants
The interior floor areas of the warehouse and trailer were contaminated with
pesticides. Soil sampling for primary pollutants and visual examination of the site
confirmed that contamination was confined to the interior floor areas of the warehouse
and trailer. Direct contact with contaminants while in the warehouse or trailer was a
threat to human health.

-------
Cleanup Approach
Response Action Status
Entire Site: Based on the results of the site investigation in 1984, the EPA
performed the following activities: sealed the warehouse opening to restrict access to
the site by trespassers; repacked the pesticides and shipped them to Long Beach,
California for disposal at a Federally-approved disposal facility; washed down all the exposed
surfaces of the storage areas with bleach to ensure deactivation of residual materials not picked
up by sweeping and vacuuming; applied two layers of epoxy paint to the interior walls and
poured concrete over the existing floor; and banned all food storage in the building and placed
warning signs on the building prohibiting food storage as an additional precautionary measure.
The EPA, with the agreement of the Government of American Samoa, deleted the site from the
NPL after determining that all the appropriate responses had been completed and no further
cleanup was necessary.
Environmental Progress
The cleanup activities at the Taputimu Farm site have been completed. The EPA deleted this site
from the NPL in 1986.

Saipan Island
Site Description
The PCB Warehouse site was a shelter in Saipan, a Commonwealth of the Northern Mariana
Islands, where drums of liquid tainted by polychlorinated biphenyls (PCBs) from transformers
were stored. The site contained 21 drums of oil contaminated with PCBs and three crates of
sodium arsemte. The drums in the shelter were intact and the EPA found no evidence of spills or
leaks on the site. The transformers from which the oil was drained were located at the Saipan
Headquarters Building and at the Yard of the Department of Public Works. The EPA found no
indication of spills or leaks near the transformers. The site was located approximately 1,000 feet
upstream from the nearest freshwater intake.
Site Responsibility:
This site was addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Deleted Date: 03/07/86
Threats and Contaminants
Three crates in the shelter contained sodium arsemte. Twenty-one drums of oil in the
shelter contained PCBs from transformer liquid. The EPA was concerned that oils
containing PCBs could be released in the event of a severe tropical storm, thereby
threatening the health of people who ingest or come into direct contact with the
contaminants.
April 1995
-------
Cleanup Approach
Response Action Status
Immediate Action: The EPA was concerned that a tropical storm could cause PCBs
to leak into the Philippine Sea from the drums and crates in the shelter. In 1984, the
EPA repacked the drums and crates and shipped them to the United States to a
Federally-approved disposal facility. The EPA tested the site after removing the wastes and found
that neither PCBs nor sodium arsenate contaminated the site and its surroundings during or
before the cleanup action. The EPA finished cleaning up the site in 1984 and, with the
concurrence of the Commonwealth of the Northern Mariana Islands, determined that no further
cleanup actions were needed.
Environmental Progress
The removal of the drums and crates has eliminated the potential for exposure to contaminants at
the PCB Warehouse site. The site now is safe for nearby residents and the environment. The
PCB Warehouse site has been deleted from the NPL.

EPA ID# GU6571999519
Site Description
PA REGION 9
Yigo
Andersen Air Force Base (AAFB) is a 20,000-acre site located in the city of Yigo on the
northern end of the island of Guam. Operational since 1940, AAFB's main purpose has been to
provide support for Strategic Air Command operations. Hazardous substances associated with
AAFB operations include: solvents such as trichloroethane (TCE) and paint thinners; dry cleaning
fluids and laundry products; fuels such as JP-4 and gasoline; pesticides; antifreeze; aircraft
cleaning compounds; and poly chlorinated biphenyls (PCBs). These substances are found in
unlined landfills, drum storage and disposal areas, chemical storage areas, fire training areas,
waste storage areas, the laundry facility, and industrial and flight line operations. AAFB is
located in a karst limestone terrain. The Northern Guam Lens is a Sole Source Aquifer
underlying the site. This aquifer supplies drinking water to at least 50 percent of the area
residents; approximately 40,200 people draw drinking water from wells located within a 4-mile
radius of the site. Groundwater sampling by the Air Force indicates the presence of heavy metals
and volatile organic compounds (VOCs). Not all contaminants can be directly linked to AAFB
operations, and background levels have not been determined for metals. An estimated 34,000
people live within a 4-mile radius of the site; 3,400 military personnel, 600 civilians, and 4,000
dependents live, work, or attend school on AAFB.
Site Responsibility:
This site is being addressed through
Federal actions.
NPL LISTING HISTORY:
Proposed Date: 02/07/92
Final Date: 10/14/92
Threats and Contaminants
Some of the areas where hazardous wastes are stored are inadequately contained and
located near sinkholes; therefore, they constitute a threat to groundwater.
Groundwater sampling indicates the presence of heavy metals, such as lead and
chromium, and VOCs including TCE, toluene, and tetrachloroethane. Surface areas,
including unlined landfills and chemical storage areas, are contaminated with VOCs,
PCBs, fuels, and pesticides. People could be at risk by ingesting or coming into direct
contact with contaminated groundwater. There are 23 endangered species living near
or on the base, which currently is being considered for designation as a wildlife and
marine preserve.
April 1995
-------
Cleanup Approach
This site is being addressed in seven stages: initial actions and six long-term remedial phases
focusing on the cleanup of different portions of the site.
Response Action Status
Initial Actions: Closure of the main base landfill in accordance with the
requirements of the Resource Recovery and Restoration Act (RCRA) was completed
in 1994. Landfill closure included the construction of a cover over the landfill.
Entire Site: An investigation of the source of base contamination began in early 1993
and is expected to be completed in 2001.
Basewide Groundwater: This investigation is scheduled to begin in 1996, and will
determine the nature and extent of ground water contamination throughout the base.
Two Landfills and Three Waste Piles: The nature and extent of contamination
posed by the waste piles are scheduled to be investigated during 1996. The landfills
are expected to be investigated in 1998.
Fire Land Disposal and Laundry Complex: The investigation of the contaminants
at these site areas began in 1994. Based on the results of this investigation,
appropriate cleanup remedies will be selected.
Four Storage and Ten Land Disposal Areas: The investigation of these areas is
scheduled to begin in 1995.
Two Storage and Eleven Land Disposal Areas: The investigation of the nature
and extent of contamination at these areas is scheduled to begin in 1995.
Site Facts: AAFB is participating in the Installation Restoration Program, a specially funded
program established by the Department of Defense (DOD) to identify, investigate, and control the
migration of hazardous contaminants at military and other DOD facilities.
Environmental Progress
Immediate threats to the health and safety of the nearby population and environment have been
reduced by the construction of the landfill cover. Further investigations will assess the nature of
contamination and the effectiveness of the initial actions at the Andersen Air Force Base site.

Site Description
The 47-acre Ordot Landfill site has been in operation since World War II. The site served as the
island's primary landfill for industrial and municipal waste, including spent industrial and
commercial chemicals, polychlorinated biphenyl (PCB)-contaminated oils from transformers, and
munitions. Analysis of groundwater, surface water, leachate, soil, and air detected several
contaminants at levels that should not affect human health. The nearest residences are 1,500 feet
from the site. The nearest groundwater well is located 1,000 feet northwest and uphill from the
site. The residents of Guam rely primarily on a sole-source aquifer located north of the site for
their drinking water. Groundwater samples indicate the landfill currently is not affecting the
quality of the municipal wells. The landfill is in a volcanic upland region, where site runoff flows
directly into the adjacent Lonfit River, which empties into Pago Bay.
Site Responsibility:
This site was addressed through
Federal and Territorial actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Threats and Contaminants
Groundwater, surface water, and leachate contained heavy metals such as iron,
manganese, and nickel. Soil was contaminated with phthalates and volatile organic
compounds (VOCs). Leachate seeped from a number of locations around the site into
the Lonfit River. Samples from both the river and the bay indicated that leachate from
the site had not caused a measurable change in the water quality. There are no
drinking water wells downgradient from the site; therefore, contact with contaminated
groundwater or surface water was unlikely.
April 1995
-------
Cleanup Approach
Response Action Status
Entire Site: In 1988, the EPA selected a "no further action" remedy for the Ordot
Landfill site. Through site studies, the EPA concluded that current threats to human
health and the environment are a result of poor landfill operation practices. Therefore,
any threats are best controlled by appropriate operation and maintenance practices enforceable
under the Clean Water Act. Groundwater monitoring wells were installed in 1992. These wells
will be monitored by the Guam EPA to ensure that contamination levels remain within established
levels. No further Superfund actions are planned, unless new information warrants a response
action.
Site Facts: In 1986, the EPA found Ordot Landfill in violation of the Clean Water Act for
discharging landfill leachate to the Lonfit River without a permit.
Environmental Progress
The investigation into the nature and extent of contamination has demonstrated that no further
Superfund actions are necessary at the Ordot Landfill site. The EPA has decided to pursue
enforcement of appropriate landfill operation and management practices under the Clean Water
Act.

Site Description
The PCB Wastes site is composed of eight separate locations scattered throughout the United
States-administered Trust Territory and several independent islands of the Pacific. These subsites
are located on the islands of Koror in the Republic of Palau, Moen in Truk State, Yap, Kosrae,
with two each on Ponape and Majuro. In 1982, an investigation revealed polychlormated
biphenyls (PCBs) in drums and transformers and some pesticides and chemicals improperly
stored at the subsites. A previous oil spill was apparent at one area formerly used to store
transformers. Some subsites stored intact transformer oil containers in unsecured areas open to
the general public. These areas represented a threat to public health and the environment because
of their proximity to human populations, groundwater supplies, and marine resources. The Trust
Territory of the Pacific Islands are populated with approximately 116,000 people.
Site Responsibility: The site was addressed through Federal
actions.
NPL LISTING HISTORY

Threats and Contaminants
Soil was contaminated with PCBs, pesticides, and other chemicals. People who came
into direct contact with contaminated soil were at risk.
April 1995
-------
Cleanup Approach
Response Action Status
Entire Site: In 1984, the subsites were cleaned up in conjunction with a larger
integrated action at 31 areas throughout the Trust Territory of the Pacific Islands.
PCB fluids were blended and burned on the islands. Other PCB and hazardous wastes
were transported to an approved disposal facility in the United States. During the removal action,
soils and waste oils were sampled in the field using a portable testing kit that allowed for the
segregation of wastes for transport. Only one subsite had contaminated soils. Testing was
conducted before and after removal of contaminated soils to determine whether PCBs remained.
No PCBs were found in structures or soils after removal actions were completed. The EPA, with
the concurrence of the Trust Territory Environmental Quality Commission, determined that all
appropriate cleanup actions had been completed at the PCB Wastes site and that no further
cleanup was required.
Environmental Progress
All the cleanup goals at the PCB Wastes site have been met through the removal of hazardous
wastes and contaminated soil, thereby eliminating all exposure pathways. The EPA has
determined that the site is now safe for nearby residents and the environment. The PCB Wastes
site was deleted from the NPL in 1986.
