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.

HAWAII
EPA ID# HID980637631
Site Description
The Del Monte Corp. (Oahu Plantation) site covers 6,000 acres in Honolulu County, on the
Island of Oahu. The surrounding area is mostly agricultural and military. Del Monte began
growing pineapple on the plantation in the 1940s. Fumigants, such as ethylene dibromide (EDB),
were used from the early 1940s until 1983 to control nematodes that infest the pineapple root. In
1980, the Hawaii Department of Health (HDOH) initiated an investigation to determine whether
the fumigants used in pineapple agriculture had contaminated drinking water wells on Oahu. As
part of the investigation, the Del Monte Kunia well, which provides drinking water to about 700
people, was sampled. The results indicated the presence of EDB and l,2-dibromo-3-
chloropropane (DBCP). As a result of the studies, HDOH ordered the well removed from
service. Following the discovery of the fumigants in the water, Del Monte, HDOH, and the
Hawaii Department of Agriculture identified two sources of the contamination. The first was an
area used to store drums of fumigant; the second source discovered was an area located near the
well where 495 gallons of EDB had spilled in 1977. Both soil and groundwater in these areas
contain high levels of fumigants. Since the discovery of the contamination, Del Monte has
initiated cleanup at the site, including the removal of 18,000 tons of contaminated soil. Despite
the cleanup, the Kunia well continues to show high concentrations of fumigants.

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: Since 1977, Del Monte has removed 18,000 tons of soil which
were spread onto a nearby field. In early 1980, the State ordered the Del Monte
Kunia well removed from service for drinking water purposes. Water from the
contaminated well is now sprinkled onto noncrop fields.
Entire Site: An investigation into the nature and extent of contamination at the site
has begun and is expected to be completed in the fall of 1996. The investigation will
lead to the selection of appropriate cleanup remedies.
Environmental Progress
The removal of the Del Monte well from service and 18,000 tons of soil have reduced immediate
threats to human health and the environment while studies leading to final cleanup of the site are
underway.

Site Description
Kokekole Pass
Pearl Harbor
The Naval Computer and Telecommunications Area Master Station Eastern Pacific (NCTAMS
EASTPAC) consists of facilities located throughout the Island of Oahu. These include facilities
at Wahiawa, Lualualei, Opana, Kokekole Pass, Pearl Harbor, and various satellite
telecommunication locations. The Navy's Initial Assessment Study identified 14 potential
hazardous waste sources at NCTAMS EASTPAC, all located at either Lualualei or Wahiawa.
The Lualualei and Wahiawa facilities are located approximately 10 miles from each other. The
Lualualei facility occupies approximately 1,700 acres in a large coastal valley on the southeastern
shore of Oahu and is surrounded by agricultural, urban, and conservation land areas. Eight
potential hazardous waste sources have been identified at the Lualualei facility, including Old
Coral Pit, Antenna 403 Disposal Area, Antenna 441 Disposal Area, Building 65 Disposal Area,
Antenna 354 Disposal Area, two wells near Building 1, Old NRTF Landfill, and Transformer
Locations. Initial investigations by the Navy to date have focused on the Antenna 354 Disposal
Area and Transformer locations. Ground water in the area is brackish; no drinking water wells
are located down stream from the facility, and neither groundwater nor surface water is used as a
source of drinking water. The Wahiawa facility occupies 700 acres on the central plateau of
Oahu and borders the Ewa Forest Reserve and other conservation land to the north and east, and
pineapple and conservation land to the south. The town of Whitmore Village borders the facility
to the west, and the City of Wahiawa is located approximately 1 mile to the southwest. From
1942 to 1977, a 6-ounce sample of fluid from each transformer was tested quarterly to evaluate
insulating properties, and was then disposed of on the ground. Once in 1988 and twice in 1990,
the Navy took soil samples around the transformers that indicated the presence of polychlorinated
biphenyls (PCBs). Approximately 248 people live in residences 200 feet from the contaminated
soil surrounding the transformers. In addition, an inactive landfill (Old Wahiawa Landfill) is
located at the facility. This landfill contains municipal solid wastes, waste lube oils, chlormated
and non-chlorinated solvents, transformer oil, hydraulic fluid, paint thinners, trichloroethane,
creosote, and mercury. Drainage from the site eventually reaches the Pacific Ocean. The
Wahiawa Public Fishing Area is located about 1/2 mile downstream of the facility in the North
Fork Kaukonahua Stream. Additional fisheries are located within 15 miles downstream,
including Kaiaka Bay, the Pacific Ocean, and the area at the merging of Poamoho and
Kaukonahua Streams. There are six Federally-designated endangered/threatened species of birds
and five Federally designated/threatened species of turtles located within 15 miles of the facility.

NPL LISTING HISTORY
Proposed Date: 01/18/94
Final Date: 05/31/94
Threats and Contaminants
Soil is contaminated with PCBs. Other contaminants such as solvents, creosote, and
mercury may be present and are being investigated by the Navy. Ingesting or touching
contaminated soil is a threat to public health and to the endangered species located near
the site.
Cleanup Approach
The site is being addressed in two phases: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Immediate Actions: In July 1990, the Navy excavated PCB-contaminated soil to
meet a cleanup goal of 10 parts per million. Soil removal activities began in late
1990 and were completed in early 1991.
Entire Site: The EPA is planning a full investigation into the nature and extent of
soil contamination. This investigation will lead to the selection of final cleanup
remedies.
Environmental Progress
After initial investigations of the site, the Navy determined that groundwater poses no immediate
threat to the community because of its limited use. In addition, the disposal of PCB-
contaminated soil has reduced immediate threats to people and the environment while the EPA
plans further site investigations.

Site Description
EPA REGION 9
Honolulu County
Pearl Harbor
The 6,300-acre Pearl Harbor Naval Complex consists of six facilities: the Naval Shipyard; the
Naval Supply Center; the Naval Station; the Naval Submarine Base; the Public Works Center;
and Inactive Ships. After being attacked by the Japanese in 1941, this naval complex became a
center of industrial activity. By mid-1943, the civilian population had reached 24,000 people. At
the end of World War II, activity declined and has since fluctuated with the Navy's requirements.
Since 1983, 31 potential sources of hazardous waste contamination within six facilities have been
identified, including unlined landfills, pesticide disposal pits, chromic acid disposal areas,
polychlorinated biphenyl (PCB) disposal areas, mercury-contaminated harbor sediments, leaking
underground solvent tanks, and waste oil facilities. Six of these potential sources have been
evaluated to date. The National Wildlife Refuge, which consists of wetlands and provides a
habitat for four endangered species, borders the site by a Navy landfill. Pearl Harbor and nearby
portions of the Pacific Ocean contain recreational and commercial fisheries, habitats for
endangered species, wetlands, and water-contact recreational areas. Land around the complex
supports agriculture; aquaculture; and industrial, urban, and commercial uses.
Site Responsibility:
The site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 07/29/91
Final Date: 10/14/92
Threats and Contaminants
Hazardous substances were found in the soil at 35 areas in the complex. These
contaminants include mercury, chromium, PCBs, pesticides, and volatile organic
compounds (VOCs). Contamination was detected in sediment samples taken from the
National Wildlife Refuge in 1988. The migration of contaminants into groundwater is
facilitated by the permeability of soils beneath the site. Touching or ingesting
contaminated soil or water could pose a health threat. There is a potential for
VOC-contaminated gases to be released into the air.
April 1995
-------
Cleanup Approach
This site is being addressed in a number of long-term remedial phase directed at cleanup of the
entire site.
Response Action Status
Entire Site: In 1993, the Navy began several investigations into the nature and extent
of contamination throughout the site to identify remedy alternatives.
Site Facts: The Pearl Harbor Naval Complex 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
Preliminary investigations have indicated that no immediate threats currently exist at the Pearl
Harbor Naval Complex site while further investigations into the nature and extent of site
contamination are underway.

Wahiawa, Oahu
Site Description
The 17,725-acre Schofield Barracks site was established in 1908 to provide a base for the Army's
mobile defense of Pearl Harbor and the entire island. Industrial operations involved maintenance,
repair, painting, and degreasing, all of which required using various organic solvents. In 1985,
the Hawaii Department of Health informed the Army that high levels of volatile organic
compounds (VOCs) contaminated wells that supply drinking water to 25,000 people at Schofield
Barracks. In 1986, the Army began removing the contaminants from the water by using an air
stripping facility. Most of the area around the barracks is rain forest. Approximately 55,000
people in Wahiawa and Mililani obtain drinking water from public wells located within 3 miles of
the base. Three miles downstream of the base is Wahiawa Reservoir, which is used to irrigate
3,000 acres of pineapple fields. The reservoir also is used for recreational activities.
Site Responsibility: This site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 07/14/89
Final Date: 08/30/90
Threats and Contaminants
Groundwater and soil contain trichloroethylene (TCE). People who drink or come into
direct contact with contaminated groundwater could be at risk. Most of the area
surrounding the barracks is a rain forest that could be affected by site contamination.
Cleanup Approach
This site is being addressed in five stages: immediate actions and four long-term remedial phases
focusing on cleanup of suspected TCE sources, groundwater, non-TCE sources, and the landfills.
April 1995
-------
Response Action Status
Immediate Actions: In 1986, the Army installed a groundwater treatment system,
consisting of an air stripper, on four existing production wells to remove or reduce
concentrations of TCE in the drinking water used at the base. The State has been
monitoring the groundwater since the contamination was discovered.
Suspected TCE Sources: The Army initiated a thorough investigation of suspected
TCE sources in late 1991. Based on the results of the investigation, scheduled for
completion in 1996, remedies will be chosen to address these sources of
Groundwater: A study of the nature and extent of groundwater contamination at the
site began in late 1991. At its conclusion, scheduled for 1997, techniques for cleaning
up groundwater contamination will be chosen.
Non-TCE Sources: In late 1991, the Army began a study of contamination from
sources other than the TCE problem areas. Recommended cleanup actions will be
provided at the conclusion of the study, scheduled for completion in 1996.
Landfills: In late 1991, the Army began a study of the presence of landfill gases and
the nature and extent of contamination of the soils and groundwater. Based on the
results of the study, scheduled for completion in 1996, appropriate cleanup remedies
will be chosen.
Site Facts: Schofield Barracks 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. A Federal Facilities Agreement between the EPA and the Army was signed in 1991
that established an enforceable schedule for addressing site contamination.
Environmental Progress
The groundwater treatment system has reduced the potential for exposure to contamination at the
Schofield Barracks site while studies continue and cleanup activities are being planned.
