Abstract |
The 11-acre Caldwell Trucking site is in Fairfield Township, Essex County, New Jersey. The site is situated on an extensive 100-year floodplain of the Passaic River and neighbors Deepavaal Brook and numerous wetlands, as well as residential and commercial properties. From the 1950s to 1984 the Caldwell Trucking Company dumped, and allowed others to dump, septic wastes into unlined lagoons and later into steel holding tanks at the site. An EPA investigation conducted between 1984 and 1986 revealed that onsite soil and a municipal well were contaminated with VOCs, PCBs, and metals. The investigation resulted in a 1986 Record of Decision (ROD) which provided for soil remediation, restoration of a municipal well, and residential hookups to municipal water. Ground water, however, remains contaminated because of a TCE-contaminated plume which extends 4,000 feet from the site towards the Passaic River. The primary contaminants of concern affecting the ground water are VOCs including TCE. The selected remedial action for this site includes pumping and treatment of offsite ground water using air stripping with offsite discharge to the Passaic River. |
