The former Electro-Voice facility in Buchanan, Michigan is a Superfund site. Before closing in 2000, the business was engaged in die-casting, machining, assembly, painting and electroplating activities. According to the EPA, "contamination at the site resulted from Electro-Voice's discharge of electroplating wastes into two clay-lined lagoons from 1952 to 1962, and from the disposal of paint wastes and solvents into a drywell from 1964 to 1973. The waste disposal activities caused groundwater to become contaminated with chemicals called volatile organic compounds, or VOCs. Following construction of the site's long-term remedy, operation and maintenance activities and monitoring are ongoing". Construction of the site's long-term remedy finished in 1999, with the EPA reporting, "soil cleanup included construction of a clay cap and active treatment by an in-place ventilation and volatilization system. Groundwater remediation is ongoing through monitored natural attenuation of pollutants".
