muskego sanitary landfill

HIGHWAY 24 & CROWBAR ROAD

The 56-acre Muskego Sanitary Landfill site is a former animal-rendering plant and gravel quarry located west of the town of Waukesha (pop. 51,000). In 1954, the site owner, Mr. Alfred Wauer, obtained a permit from the city of Muskego to operate the site as a public dumping ground. In 1969, Acme Disposal, a subsidiary of Waste Management of Wisconsin, Inc. (WMWI), leased the property and continued operations at the dump. The site was licensed by the Wisconsin Department of Natural Resources (WDNR) in 1971 as a sanitary landfill. In 1975, WDNR determined that the quality of groundwater was deteriorating in the vicinity of the site and subsequently ordered WMWI to cap and close the site. By 1976, the landfill had been renamed the Muskego Sanitary Landfill and was operated directly by WMWI. Groundwater contamination was discovered in 1982, when WDNR reviewed data in response to a request from WMWI for approval to do repair work on both fill areas. In 1987, WMWI was issued a unilateral administrative order (UAO) to finance and conduct the remedial investigation (RI) at the site. Finally, a second UAO was issued in June 1995 to address the groundwater issues. Site Responsibility This site is being addressed through federal, state, and potentially responsible parties' actions and is considered a federal enforcement lead site.
