SITE DESCRIPTION/RESOLUTION OF ENVIRONMENTAL CONCERNS:
As
of 28 June 2004
The site was originally a sand and gravel pit before it was converted
into a private landfill in 1969. During the early 1970s, industrial wastes
were disposed of at the site. Records indicate that liquid chemical wastes
were poured directly into the landfill as well as buried in 55 gallon
drums. It is estimated that nine million gallons of chemical wastes were
disposed of at the landfill in this manner. The operator of the landfill
stopped accepting chemical wastes in 1972 and ceased operations entirely
in 1978. In the early 1980s, state and local officials determined that
contaminated ground water at the landfill presented a substantial threat
to nearby private potable wells and the Atlantic City Well Field, which
was located less than a mile away. In 1982, USEPA placed the landfill
on the National Priorities List of Superfund sites and NJDEP began a Remedial
Investigation and Feasibility Study (RI/FS) to determine the extent of
the contamination and evaluate cleanup alternatives. USEPA issued a Record
of Decision (ROD) with NJDEP concurrence in 1983 that required relocation
of the Atlantic City Well Field and replacement of private potable wells
with public water supplies. This work was completed in 1985. Based on
the RI/FS, NJDEP determined that the ground water at Prices Landfill was
significantly contaminated with a variety of volatile organic compounds
and metals, including benzene, vinyl chloride, cadmium and lead, and that
a plume of contaminated ground water was migrating off site. In 1986,
after the RI/FS was completed, USEPA issued a second ROD for the site
with NJDEP concurrence that required the following actions: 1) installation
of a security fence around the landfill; 2) installation of an on-site
remediation system to collect and pretreat contaminated ground water and
landfill leachate, followed by discharge of the treated effluent to the
Atlantic County Wastewater Treatment Facility (ACWTF); 3) installation
of a cap over the landfill; and 4)
implementation of a long-term ground water monitoring program to evaluate
the effectiveness of the remedial actions. Progress on the ground water
remediation system was delayed when ACWTF changed its discharge criteria
and would no longer accept treated effluent from the landfill, which required
NJDEP to modify the Remedial Design to incorporate discharge of the treated
effluent to the ground water through infiltration galleries. NJDEP completed
construction of an interim ground water remediation system at the landfill
in 2000. The interim system collects contaminated ground water from a
recovery well on the eastern side of the site, conveys it to an on-site
treatment system that removes the volatile organic compounds, and discharges
the treated water into an infiltration gallery located on the landfill.
It currently extracts and treats approximately 100,000 gallons of ground
water each day. The interim system will be evaluated and modified over
a period of two years to optimize its performance. NJDEP began the Remedial
Design for the landfill cap and a final ground water remediation system
in 2002. The Remedial Design is expected to be completed in 2004. |
