Superfund Site Profile
The 58-acre Laurer I Sanitary Landfill site (also known as the Boundary Road Landfill) is located in Menomonee Falls, Wisconsin. A landfill on site accepted municipal and industrial wastes until 1973. It took several years for the owners to vegetate the cover and properly abandon the site. In 1973 and 1974, state inspectors identified holes in the berm around the site that allowed leachate from a collection pond to escape into a ditch that drains into the Menomonee River. In 1981, the owner installed an underground wall of clay materials between the landfill and the pond to stem the flow of leachate. Currently, Waste Management of Wisconsin (Waste Management) collects leachate accumulating behind the cutoff wall and sends it to a municipal wastewater treatment plant. Following construction of the site’s remedy, operation and maintenance activities and monitoring are ongoing.
