The 9.5-acre Thermo Chem site is comprised of an inactive solvent and chemical waste reprocessing, refining, and incineration facility, and an inactive waste hauling facility in Egelston Township, Muskegon County, Michigan. The site is adjacent to two other Superfund sites: the SCA Independent Landfill site, and the Bofors Nobel site. The Thomas Solvent Company, which lies adjacent to, and is owned by Thermo Chem, has been included as part of the site because it is suspected to be a source of ground water contamination. The Thomas Solvent Company was operated as a hazardous waste hauling facility for Thermo Chem and collected waste for recycling and returned the material to customers. In response to investigation activities during 1988 and 1991, EPA conducted an emergency removal of drums and materials containing hazardous waste. The Record of Decision (ROD) addresses the source of contamination by remediation of soil, sludge, debris, and ground water up to the point where ground water discharges into Black Creek as Operable Unit 1 (OU1). A future ROD will address OU2, the contamination problems within Black Creek and ground water contamination south of Black Creek. The primary contaminants of concern affecting the soil, sludge, and ground water are VOCs including benzene, toluene, and xylenes; other organics including PAHs, PCBs, and pesticides; metals including arsenic, chromium, and lead; and other inorganics. The selected remedial action for this site is included.
