EPA added the Kauffman & Minteer, Inc. site in Jobstown, New Jersey (Burlington County) to the Superfund National Priorities List on March 30, 1989 because of harmful chemicals that were detected in lagoon sediments, shallow ground water and on-site soil. Company-owned tanker trucks transported bulk liquids, including synthetic organic chemicals, plastics, resins, vegetable oils, petroleum and alcohol. From 1960 to 1980, the company discharged wastewater used to clean the trucks into a drainage ditch and an unlined lagoon site. In 1984, a lagoon dike broke allowing wastewater to migrate off-site to a neighboring property and into wetlands. Discharges from the lagoon and the washing areas contaminated shallow groundwater beneath the site and threatened the Wenonah-Mount Laurel aquifer.
In 1991, EPA initiated a remedial investigation and completed a feasibility study to identify and screen cleanup alternatives. A Record of Decision (ROD) was signed in 1996, and soil excavation, off-site disposal of lagoon and drainage ditch sediments were undertaken; long-term monitoring of the contaminated shallow groundwater was initiated; and institutional controls were put into place to limit groundwater use in the shallow groundwater. Another soil removal was completed in 1998.
A second ROD was signed in 2002. The major components of this selected remedy include: In-situ treatment of the contaminated soil and groundwater; Extraction and treatment of the contaminated groundwater; establishment of institutional controls; and groundwater monitoring to ensure effectiveness of remedy.
EPA started the first phase of the Remedial Action in 2007. In-Situ Chemical Oxidation involves the injection of chemical oxidants into the subsurface to destroy organic contaminants in soil and groundwater. The main objective of chemical oxidation is to transform undesirable chemicals into chemicals that are harmless or not objectionable.
