This project will support source tracking to determine if there remains a significant source of PCBs entering the system. Supported in this effort is the Michigan Department of Environmental Quality. Specifically this project will use caged mussels strategically depolyed along 15 transects in the lower river to provide spatial resolution sufficient to isolate hot spots if they exist. Results of this study will be combined with other studies (spiders, swallows, Hester Dendys, passive samplers) and used as scientific evidence to determine if additional PCB remediation is needed and where.
