Lower Green Bay and Fox River Area of Concern
The Lower Green Bay and Fox River was designated an Area of Concern under the 1987 Great Lakes Water Quality Agreement. The AOC is primarily contaminated with PCBs from industrialization. Since 1988, over 3/4 of the 120 remedial actions recommended by the Lower Green Bay Remedial Action Plan have been implemented or initiated.
The seventh year of dredging in the Lower Fox River from DePere to Green Bay resumed on March 30, 2015. Three hydraulic dredges will be used to remove about 458,000 cubic yards of PCB-contaminated sediment this year. Similar to previous years, dredging will take place 24 hours per day, at least five days a week through early November (except for holidays). The entire cleanup is scheduled to be completed by 2017.
