Superfund Site Profile
The Janeville Disposal Facilities are located on a 65-acre parcel of land on Black Bridge Road in Rock County, Wisconsin.
The Janesville Ash Beds site operated from 1974 to 1985. It comprises five ash beds in an area about 400 feet by 400 feet. Industrial liquids and sludges were deposited in this area and allowed to evaporate. Dried sludge was then disposed of in two adjacent landfills: the "Old Landfill," another Superfund site, and the "New Landfill." Both are now closed.
The primary contaminants in the groundwater were volatile organic compounds (VOCs) such as tetrachloroethene, trichloroethene, and vinyl chloride. 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, there are about 12 homes within one-half mile to the northwest of the site. Groundwater monitoring is ongoing.
