The 9-acre Waste Research & Reclamation CO. (WRR) site is located in Eau Claire, Wisconsin. A roofing company operated on site from the 1970s to 1981. WRR has occupied the site since then. WRR is primarily a reclamation and recycling business for hazardous liquid wastes, fuel blending and transportation of hazardous waste for incineration or disposal. Facility operations contaminated soil, surface water and groundwater with hazardous chemicals. The site is now being managed under the Resource Conservation and Recovery Act (RCRA); EPA took the site off the Superfund program�s National Priorities List (NPL) in 1993.
