St Clair River Area

St. Clair River Area of Concern (AOC)

The St. Clair River AOC is shared between Michigan and Ontario, Canada. It was originally identified as an AOC due to contamination in the river and the soil. This contamination includes heavy metals, E. coli and chemicals such as mercury, dioxins and polychlorinated biphenyls (PCBs). Industrial, urban, agricultural and navigational developments have contributed to the breakdown of wetland, river and shoreline habitats.
