SEDIMENT

摘要

The Fox River cleanup project is a project near Green Bay, Wisconsin designed to reduce risk to human health and the environment due to the presence of PCBs in Fox River sediment. This multi-year cleanup effort includes dredging, capping with coarse sand, the separation of clean sand and dewatering of fine sediments with membrane presses. It's currently one of the largest cleanup projects of its kind in the world and its unique approach will remove approximately 3.8 million cubic yards (cy) of PCB-contaminated sediments and place a protective cap or sand cover over 600 acres. In addition, billions of gallons of water removed from the river will be treated and returned.
