The Sauk County Landfill site is located in Sauk County, Wisconsin. Sauk County operated a municipal landfill on site from 1973 to 1983. The landfill occupies about 14 acres of a county-owned 320-acre parcel of land. Municipal, commercial and industrial wastes were disposed of at the site. Sauk County closed and capped the landfill in 1983. Facility operations contaminated groundwater with volatile organic compounds (VOCs) and metals. Following construction of the remedy, operation and maintenance activities and monitoring are ongoing.
