The Peerless Plating Company site, about one acre in size, is located within a mix of light industrial and residential land uses. Electroplating operations conducted at the facility (1937-1983) included copper, nickel, chromium, cadmium, and zinc plating in processes that required the use of toxic, reactive, corrosive, and flammable chemicals. U.S. EPA conducted emergency removal actions in 1983 and 1991. The 1992 ROD called for building demolition, groundwater pump and treat for VOCs followed by chemical precipitation of inorganics, soil vapor extraction, and excavation and stabilization of inorganics. Construction and startup of these remedies was completed in 2001. In 2012 EPA agreed to undertake, with MDEQ approval, a separate remedial action to include in situ soil treatment and installation of a permeable reactive barrier (PRB) along Little Black Creek to address the remaining cadmium source-area contaminated soils. Results of a pilot test of in situ chemical reduction (ISCR) in 2014 were positive, and both agencies agreed to implement the full-scale remedy in July 2015. Injections took place from mid-August to early October 2015, and the ISCR and PRB remedies operated throughout 2016. At least four years of quarterly groundwater sampling will be conducted to evaluate the effectiveness of the remedy. http://www.michigan.gov/documents/deq/deq-rrd-SFS-2016SuperfundLegislativeReport_559627_7.pdf See additional information in the site's fourth 5-year review (2017) at https://semspub.epa.gov/src/document/05/534560.
