Site Description 	

The approximately 60-acre GEMS Landfill site has been owned by Gloucester Township from at
least the late 1950s to the present. During that time, the landfill has been operated by various parties
as a disposal site for solid, liquid, and hazardous wastes and substances. Records indicate that a
variety of industrial wastes including asbestos, solvents, and other materials were disposed of at the
GEMS site between 1970 and 1979. In 1980, sludge from the City of Philadelphia's northeast
wastewater treatment facility was disposed of at the site. Analyses of the sludge revealed the presence
of pesticides. The State closed the landfill in 1980. Scattered industrial and recreational areas are
adjacent to the site. The closest residences are approximately 300 feet from the base of the landfill.
Approximately 6,000 people live within a mile of the site, and 38,000 people live within a 3-mile
radius. Holly Run borders the eastern edge of the site and flows into Briar Lake off the northeast
corner of the site.

Site Responsibility: This site is being addressed through

Federal, State, and potentially
responsible parties' actions.

NPL LISTING HISTORY

Final Date: 09/01/83

Threats and Contaminants

The site is contaminated with VOCs, heavy metals and trace amounts of pesticides
including DDE, DDD and DDT. The ground water beneath and near the site is also
contaminated with organics and inorganics from the site.

Cleanup Approach

This site is being addressed in three stages: immediate actions and a long-term remedial stage
comprised of two phases focusing on cleanup of the entire site.

Response Action Status

Immediate Actions: In 1983, EPA removed debris from the site and constructed a
partial fence and two culverts and a berm to prevent residents from coming in contact
with wastes in the area and control drainage from the site.

Entire Site: In 1985, EPA selected the following remedy to clean up the site: (1)
i constructing a landfill cap and regrading existing landfill side slopes; (2) installing an
active gas collection and treatment system, a groundwater/leachate treatment system, and
surface water controls; (3) implementing a monitoring program; and (4) relocating and isolating
Holly Run and installing limited runoff controls. In addition, potentially affected homes have been
connected to the existing public water supply system.

Site Facts: In 1980, the State of New Jersey initiated litigation in State Court which was
subsequently moved to Federal District Court in 1984. This action sought recovery of the State's past
response costs and performance of work at the site. In September 1992, the United States Department
of Justice, on behalf of EPA, filed a civil action against nine defendants pursuant to the Superfund
law. By this action, EPA sought to recover certain costs incurred by the United States in response to
the release and/or threat of release of hazardous substances at the site. Including third party
defendants, the State action involved some 300 parties including the nine sued by the United States.
In November 1992, the two actions were consolidated, and extensive settlement discussions were
commenced resulting in a global consent decree settlement which was completed in fall 1996. The
Consent Decree document was entered in Federal Court on June 27, 1997.

Cleanup Progress =^= (Actual Construction Underway)

Phase I activities, consisting of all of the remedial measures identified above with the exception of
the groundwater/leachate treatment system, were completed in August 1994. The final engineering
design for Phase II, consisting of construction of an on-site groundwater/leachate pre-treatment
facility with discharge to the local POTW, and extensive groundwater and vegetative monitoring
programs, was completed by the potentially responsible parties in February 1998. Construction of the
groundwater/leachate treatment system was begun in July 1998 and is scheduled to be completed in
early 2002. A three month surface water trial will begin in April 2002 which will provide data to
evaluate the final method of treated water discharge. Startup is also anticipated to begin in the
summer of 2002.
