One of the RAP goals is to implement Superfund remediation of the in-place sediments in the River and Harbor. The RAP suggests that the Federal government address policy concerns including the role of the state and federal government in the disposal of sediments. The RAP urges the Federal government to look to alternate disposal methods for sediment remediation. The site area includes Sheboygan Harbor, located on Lake Michigan, and the lower Sheboygan River, which discharges into the Sheboygan Harbor. Since then, PCBs have been detected in fish, wildlife, surface water, sediments in the harbor and river and in flood plain soils.
Concentrations decline farther downstream from the plant.
The PRP excavated PCB contaminated soils from its property along the river and disposed of them off site in 1978. People who come in direct contact with or ingest contaminated soil, sediments, or surface water may be at risk. Because fish and wildlife are contaminated with PCBs, people who eat contaminated fish or waterfowl also may suffer adverse health effects. In 1978, the State advised residents not to eat fish from the Sheboygan River and two tributaries, the Mullet and Onion Rivers, because of PCB contamination. In 1987, the State also issued an advisory not to eat wildlife from the area.
