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.
