Initial Notification: Primarily, the problems in the River Raisin, Michigan Area of Concern (AOC) are heavy metals and PCBs. These pollutants have contaminated sediments, water, and fish. Heavy metals found in sediment include copper, zinc, and chromium. Oil and grease have also been found in river and harbor sediment. Planning for the cleanup of the AOC has been underway since 1987. Industrial and municipal discharges of these substances in the past have left a legacy of problems in the AOC. Several potential nonpoint sources of contaminants are the result of historic discharges. Potential sources include Port of Monroe landfill, industrial landfills, waste piles, City of Monroe landfill, and contaminated sediment in the harbor and river. USCG district 9.
