SITE DESCRIPTION/RESOLUTION OF ENVIRONMENTAL CONCERNS:
As
of 28 June 2004
Florence Land Recontouring (FLR) Landfill operated as a municipal disposal
facility from 1973 to 1981. The landfill was permitted to accept sanitary
wastes, including sewage sludge and non-chemical industrial wastes; however,
an investigation by NJDEP in 1975 found that hazardous wastes had been
illegally disposed of at the site. The New Jersey Superior Court ordered
the site closed in 1979 due to concerns that it was contaminating the
ground water. The operator installed a clay cap over the landfill and
leachate collection system in 1982. After the landfill was closed, leachate
seeps were observed at the banks of a nearby creek and landfill gases
were found to be emanating from on-site manholes and monitoring wells.
USEPA added FLR Landfill to the National Priorities List of Superfund
sites (NPL) in 1984.
Between 1985 and 1986, NJDEP conducted a Remedial Investigation and Feasibility
Study (RI/FS) to determine the nature and extent of the contamination
at the site and evaluate cleanup alternatives. The RI/FS revealed that
contamination from the landfill had migrated into the underlying shallow
aquifer but the deeper Magothy-Raritan Aquifer was not affected. The RI/FS
also revealed that the shallow ground water contamination had not migrated
laterally beyond the boundaries of the site. In 1986, USEPA signed a Record
of Decision (ROD) with NJDEP concurrence that required installation of
a multilayer landfill cap, a circumferential slurry wall, storm water
controls, leachate and landfill gas collection systems and perimeter fencing.
NJDEP completed construction of the remedial actions in 1994. Operation
and maintenance (O&M) of the cap and engineering control systems are
currently being implemented by Burlington County under the oversight of
NJDEP.
