The Janesville Old Landfill site is being remediated concurrently with the Janesville Ash Beds site and two nearby, non-NPL sites, the Janesville Old Dump and the Janesville New Landfill sites. These four sites comprise the 65-acre Janesville Disposal Facility (JDF) in Janesville, Wisconsin. The 18-acre Janesville Old Landfill site was operated from 1963 to 1978, accepting both municipal and industrial wastes. The site was capped with silty sand and sandy clay at the time of closure in 1978, but was subsequently shown to be contributing to air and ground water contamination. A 1986 Consent Order authorized that the four sites comprising the JDF would be addressed in one remedial investigation under the joint authority of CERCLA and RCRA. The primary contaminants of concern affecting the ground water and air are VOCs including benzene, PCE, and TCE; and metals including arsenic. Remedial activities at the JDF site will be implemented at three of the sites and include treating the landfill gas by extraction and flaring, upgrading the landfill cap, and air monitoring at the Old Landfill site.
