janesville ash beds


The Janesville Ash Beds Site is located on a 65-acre parcel of land in Rock County, Wisconsin. The parcel contains four different areas [two Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites and two Resource Conservation and Recovery Act (RCRA) units]: the Janesville Ash Beds, the Old Dump, the Old Landfill, and the New Landfill. All four sites have been combined as the Janesville Disposal Facility (JDF) and are being addressed jointly under CERCLA and RCRA. The Janesville Ash Beds site comprises five ash beds in an area of approximately 400 feet by 400 feet. Industrial liquids and sludges were deposited in this area and allowed to evaporate. The resultant dried sludge was then disposed in two adjacent landfills: the Old Landfill, another National Priorities List (NPL) site, and the New Landfill, a RCRA-regulated unit. Both are now closed. The Site operated from 1974 to 1985. The primary contaminants in the groundwater downgradient of the site were volatile organic compounds (VOCs) such as tetrachloroethene, trichloroethene, vinyl chloride, 1,1-dichloroethene, and 1,2-dichloroethene. The area surrounding the ash beds is industrial property and vacant land. There are no private residential wells or municipal supply wells in the line of the groundwater plume between the facility and the Rock River, the groundwater discharge point. However, approximately 12 residences exist within one-half mile, to the northwest of the site. Site Responsibility The Potentially Responsible Parties (PRPs), pursuant to a Consent Decreee (CD) with the U.S. EPA, performed the cleanup of the combined Janesville Disposal Facility sites. The work peformed by the PRPs was approved by U.S. EPA, with the assistance of the Wisconsin Department of Natural Resources (WDNR).
