The Fox River Cleanup Project was designed to reduce risk to human health and the environment due to the presence of PCBs in Fox River sediment, The multi-year cleanup effort included dredging, capping and covering over a 13-mile stretch of the Lower Fox River.
The project officially started with dredging and processing in spring 2009. Dredging, capping and covering operations were completed this summer.
Dredging involves removing sediment from the riverbed. The sediment is dewatered and the resulting filter cake material is transported by truck to a landfill.
Capping and sand covering involves adding cover above PCB containing sediment by placing sand and gravel on the river bottom. Capping and covering further prevents the PCBs from being released into the river. The thickness of the caps vary from a six inch sand cover to a 33 inch cover of sand, gravel and quarry stone.
As part of the Fox River Cleanup Project, a processing facility was constructed along the river in Green Bay where dewatering, sediment processing and water treatment take place.
A staging facility is located in Ashwaubenon to support the pipeline to the spreader barge and manage capping and covering materials. There is no contaminated sediment at the staging area. Contaminated sediment is handled only at the Green Bay Processing Facility.
A Transportation Plan is in place outlining primary and secondary routes for trucking processed sediment for disposal.
Throughout the project, safety is a top priority. Rigorous health and safety plans are in place for all aspects of the project, including safety on the river for project workers as well as boaters, anglers and other recreational river users.
