Background
The Master Disposal Service Landfill (MDSL) site is located at 19900 West Capitol Drive in the town of Brookfield, Waukesha County, Wisconsin. The site occupies a 40-acre parcel of land, of which 26 acres comprise a now inoperative landfill. The site is on the marshy floodplain of the headwaters of the Fox River, which flows southwest into Illinois. It is estimated that 1,416,000 cubic yards of waste, including 1.5 million gallons of industrial wastes such as solvents, paints, adhesives, oils, and foundry waste were disposed of at the site when the MDSL operated between 1967 and 1982. The site was partially closed in 1982, but the cover materials used at the time were derived from an onsite source with an inadequate clay content. Erosion of the cap and subsequent reexposure of waste materials became a problem.
On September 21, 1984, the site was listed on the National Priorities List (NPL). In June 1986, about 20 potentially responsible parties (PRPs) entered into an Administrative Order on Consent (AOC) with the United States Environmental Protection Agency (U.S. EPA) and the Wisconsin Department of Natural Resources (WDNR) for the purpose of performing a remedial investigation and feasibility study (RI/FS). The goal of the RI/FS was to determine the impact of the site on the surrounding environment and to explore alternatives for cleaning up the site.
