This $650-million, nine-year remediation project is the world’s largest PCB cleanup in history. The massive project is dredging and processing 3.8 million cu yd of river sediment contaminated with polychlorinated biphenyls that can cause severe health problems for wildlife and for humans who eat fish from PCB-contaminated spots.
It will clean up 13.3 miles of the lower Fox River near Green Bay in northeastern Wisconsin.
