SITE DESCRIPTION/RESOLUTION OF ENVIRONMENTAL CONCERNS:
of 28 June 2004
The Denzer & Schafer X-Ray Company formerly operated a silver reclamation
facility at this site. The industrial process entailed using caustic chemical
solutions to strip silver from x-ray film. Between 1974 and 1981, the
facility discharged its process waste water to an underground septic system.
NJDEP ordered the facility to cease the discharge to the septic system
in 1981 and required the owner to install monitor wells to determine whether
ground water quality at the site had become degraded due to past discharges.
Sampling of the monitor wells confirmed that the underlying shallow aquifer
was contaminated with volatile organic compounds and metals. Due to the
potential for the contamination to migrate downward and affect domestic
and public water supply wells in the area, USEPA added the Denzer &
Schafer facility to the National Priorities List (NPL) of Superfund sites
in 1983. Between 1987 and 1995, NJDEP's Remedial Response Element conducted
a Remedial Investigation and Feasibility Study (RI/FS) to delineate the
contamination in the soil and ground water and evaluate cleanup alternatives.
The RI/FS revealed that the volatile organic contamination detected in
the ground water early in the investigation had largely dissipated due
to natural biodegradation and attenuation. The RI/FS also revealed that
the metals contamination in the ground water did not pose a risk to any
private or public wells. Sampling of the surface and subsurface soils
across the site and surface water from a ponded area did not indicate
contamination above levels of concern. In 1995, NJDEP issued a Record
of Decision (ROD) with USEPA concurrence that called for no action at
the site except for monitoring. Under the no action with monitoring remedy,
there will be no remedial action to address the residual ground water
contamination; however, monitoring of the ground water, surface water
and sediments would be conducted for a period of at least five years to
ensure the concentrations of contaminants in these media remain below
levels of concern. The ROD also required establishment of a ground water
Classification Exception Area (CEA) at the site to ensure that proper
precautions are taken if any new potable wells are installed at the property.
Shortly after the ROD was signed, the owner of the Denzer & Schafer
company abandoned the facility and left drums of hazardous materials inside
the process building and in a storage trailer that was parked on site.
USEPA disposed of the drums of hazardous materials during a Removal Action
in 1996 and a private party interested in developing the area subsequently
demolished and disposed of the building. USEPA removed the Denzer &
Schafer site from the NPL in 1998. NJDEP is periodically monitoring environmental
conditions at the site pursuant to the requirements of the ROD.
