GLIN==> PCB Levels Continue Decline in Manistique Harbor Following Sediment Cleanup




Post-cleanup studies of Michigan's Manistique Harbor and River show declining levels of PCB contamination, according to U.S. Environmental Protection Agency studies.

EPA oversaw a $48 million Superfund cleanup, which involved dredging and removal of 190,000 cubic yards of sediment from the harbor bottom. The sediment was contaminated by PCB discharges from industrial facilities from the 1950s through the 1980s. Dredging was completed in 2000.

EPA completed a study of sediment, surface water and fish in late 2004, with comprehensive data analysis performed during 2005. A second, smaller-scale sampling effort was performed in 2005, with the data analysis completed recently.  Results from the two studies show encouraging trends for ecological recovery of the harbor.
