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.
