HARBOR

The Sheboygan Harbor & River site extends approximately 14 miles through the communities of Sheboygan Falls, Kohler, and Sheboygan, Wisconsin. The site area includes Sheboygan Harbor, located on Lake Michigan, and the lower Sheboygan River, which discharges into the Sheboygan Harbor. In 1977, the State of Wisconsin detected polychlorinated biphenyls (PCBs) during routine sampling of fish. PCBs were later detected in fish, wildlife, surface water, sediments in the harbor and river, and in floodplain soils. The highest concentrations of PCBs were detected in sediments immediately downstream from a die-casting plant in Sheboygan Falls, with concentrations declining farther downstream from the plant. The potentially responsible party (PRP) excavated PCB-contaminated soils from its property along the river and disposed of them offsite in 1978. The Sheboygan River drains into Lake Michigan, the source of drinking water for approximately 58,000 people within the Sheboygan/Sheboygan Falls/Kohler metropolitan area. The U.S. Environmental Protection Agency (EPA) proposed the site for the National Priorities List (NPL) in September 1985 and finalized the site on the NPL in June 1986. Site Responsibility The Site is being addressed by the PRP with EPA oversight.
