Site Description
The seven-acre Liquid Disposal, Inc. (LDI) National Priorities List (NPL) site is located in Shelby Township in Macomb County, Michigan. LDI was a commercial liquid waste incineration facility which accepted wastes from major automobile manufacturers, chemical companies, and other industries around the state. Site facilities included an ash pit, scrubber and oil lagoons, surface and underground storage tanks, and an assortment of drums. Indiscriminate storage practices and spills led to soil and groundwater contamination with volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and numerous heavy metals, including barium, cadmium, and lead. The site is bordered on two sides by wetlands and the Clinton River and on the south side by an auto junkyard. The Rochester-Utica State Recreational Area and the Shadbush Tract Nature Study Area are within one mile of the site. Approximately 54,000 people live within three miles of the site; an estimated 3,500 people rely on groundwater for household use.Site Responsibility
This site is being addressed through federal, state, and potentially responsible parties' actions.Threats and Contaminants
Soil and groundwater are contaminated with VOCs, PCBs, PAHs, and numerous heavy metals, including barium, cadmium, and lead.Cleanup Progress
Between 1982 and 1986, the United States Environmental Protection Agency (U.S. EPA) in cooperation with the Michigan Department of Natural Resources removed lagoon wastes; contaminated sediments; approximately two million gallons of liquid waste; 2,800 cubic yards of heavy metal sludge; and 200 drums from the site. Between 1987 and 1991, six settlements resolved the liability of hundreds of small generators. In 1992, 35 major potentially responsible parties (PRPs) signed a Consent Decree (CD) with U.S. EPA for final cleanup of the site. The PRP group has completed the following work:
- Solidification with concrete of a 20- foot wide swath of perimeter site soil and highly contaminated soil and debris on site
- Construction of an underground slurry wall inside the 20-foot solidified swath around the perimeter of the site
- Construction of a clay cap over the site
- Installation of extraction wells inside the slurry wall and monitoring wells inside and outside the wall
- Soil replacement and revegetation of a wetlands and uplands area east of the site
