The 7-acre Liquid Disposal, Inc. (LDI) site is located near the northwest corner of the intersection of Ryan and Hamlin Roads in Shelby Township in Macomb County, Michigan. During its history, the site was used as a sand and gravel pit, a landfill, and for the storage and incineration of liquid industrial wastes. From 1968 through 1982 liquid industrial wastes awaiting incineration were stored in lagoons, 55-gallon drums, underground tanks and aboveground tanks. Wastes received for incineration included polychlorinated biphenyls (PCBs), solvents, paints, laboratory wastes and various contaminated soils.The United States Environmental Protection Agency (U.S. EPA) proposed the site for the National Priorities List (NPL) in December 1982 and officially listed the site on the NPL in September 1983. During the period of 1982 through 1986, the EPA performed four major removal actions at the site. The cleanup remedy included on-site land disposal of debris, on-site solidification / fixation of soil and waste, extraction and treatment of groundwater, installation of groundwater monitoring wells, landfill slurry wall and cap construction. The cleanup remedy was officially completed with the signing of the Preliminary Close Out Report (PCOR) on September 15, 1997.

The EPA conducted its most recent five-year review in 2008 and is set to begin its fourth five year review for final completion by mid-June of 2013. The assessment conducted for the 2008 review found that the remedy was constructed as specified in legal and technical documents between the EPA and the potentially responsible parties. The only exception was that a slurry wall with an inward hydraulic gradient is required for the site to comply with the requirements.
