摘要

The 1-acre Peerless Plating site is a former electroplating facility in MuskegonTownship, Michigan, and is located northwest of Little Black Creek and 1 mile north of Mona Lake. Lake Michigan supplies drinking water for residential and commercial businesses within a 3-mile radius of the site. From 1937 to 1983, onsite electroplating operations and processes included copper, nickel, chromium, cadmium, and zinc plating, in addition to burnishing, polishing, pickling, oiling, passivating, stress relieving, and dichromate dipping. In the 1970s, the state directed Peerless Plating to monitor waste discharge daily and to install a treatment system to meet reduced effluent limitations. The site violated the requirements and was charged by the state. The ROD addresses the onsite contaminated soil and ground water as a final remedy. The primary contaminants of concern are VOCs, including benzene, TCE, toluene, and xylenes; metals, including arsenic, chromium, and lead; and inorganics, including cyanide. The selected remedial action for the site are included.
