Fox River dredging begins for 2014 season

GREEN BAY, WI (WTAQ) - The dredging of old cancer causing PCB's and the removal of shipwrecks has resumed in Green Bay.

Tetra Tech has resumed its work, after shutting it down for the winter on the Fox River behind its production facility. It's part of a long-range effort to remove the PCB's that were dumped in the river in the 1950's and 60's, as part of the process of making copy paper without carbons.

Since the project began in 2009, over two million cubic yards of sediment have been dredged from the Fox River. Tetra Tech plans to remove another 670,000 cubic yards this year.

Also, Tetra Tech has a subcontractor removing a cluster of sunken tugboats at the site from the 19th century. The boats went down in the 1940's in a spot that's now part of the National Register of Historic Places.

Because of that, the company reached an agreement with the federal and state governments on the clean-up work. The recovered vessels will later become part of a Green Bay museum display.
