Superfund Site: ANDERSON DEVELOPMENT CO.
Superfund Site Profile
The Anderson Development Company (ADC) manufactures specialty organic chemicals on a 12-acre facility in Adrian, Michigan, and sells the products to other manufacturers. ADC produced the chemical 4,4'-methylene-bis-2-chloroaniline (MBOCA) from 1970 to 1979 under the trade name of Curine 442. MBOCA is used as a curing agent for polyurethanes and epoxy resins. It is a highly toxic compound that can be absorbed through the skin. MBOCA contamination was found in high concentrations in sludges in a pretreatment lagoon and lower concentrations in sediments and soil within a two-mile radius of the ADC facility in 1979. In 1980 and 1981, the Michigan Department of Natural Resources (MDNR), ADC and Lenawee County Health Department conducted an extensive cleanup and monitoring program that included sampling of nearby surface soil and home carpet vacuum dust testing. Following construction of the site’s long-term remedy, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1996.
