Superfund Record of Decision (EPA Region 2): Imperial Oil/Champion Chemicals, Marlboro Township, Monmouth County, NJ. (First remedial action), September 1990

Technical Report · Wed Sep 26 00:00:00 EDT 1990

OSTI ID:5324654

The 15-acre Imperial Oil/Champion Chemicals site is an active oil blending facility in Marlboro Township, Monmouth County, New Jersey. Surrounding land use is primarily residential, and several contaminated wetland areas are located to the north of the site. Since 1912, a variety of operations have taken place onsite, including food processing, chemical manufacturing, and flavor and essence production. Residual sludge and oily filter clay were disposed of onsite and wash water was discharged to an onsite settling lagoon. In 1969, Imperial Oil began onsite oil blending operations that included mixing and repacking unused oil. The resulting oil/water separator sludge reportedly has been disposed of onsite near the oily filter clay pile. Several private and State investigations from 1981 to 1990 revealed contamination in onsite soil and ground water, as well as contamination by oily sludge in two of the offsite wetland areas. Probable sources of the contamination include leaching and erosion of material from an onsite waste pile, overflowing of oil/water separators, and improper treatment of separator effluent for arsenic. The Record of Decision (ROD) addresses remediation of the contaminated offsite wetland areas. Remediation of onsite sources and contaminated ground water will be addressed in a subsequent ROD. The primary contaminants of concern affecting the soil are VOCs including benzene, toluene, and xylenes; other organics including PAHs and PCBs; and metals including arsenic, chromium, and lead.
