Detroit River's Black Lagoon Project

This photo shows the silt curtain that was
constructed
around the Black Lagoon to keep
re-suspended
sediment from entering the river.
More than 470,000 pounds of contaminants were removed from the Black Lagoon inlet on the Detroit River, completing the first cleanup project made possible by the Great Lakes Legacy Act. U.S. Environmental Protection Agency’s Great Lakes National Program Office and Michigan Department of Environmental Quality coordinated the removal of 115,000 cubic yards of polluted sludge from the small bay during the $9.3 million project.
Dredging of the polluted mud began in October 2004 and took
thirteen months. The sediment was dredged out of the lagoon and the
sludge was solidified before being transferred by truck or barge to
the Pointe Mouille Confined Disposal Facility. After the dredging
phase was completed, the bottom of the lagoon was covered with 6
inches of sand and 3 inches of stone to protect fish and wildlife
from any remaining contamination in the river mud. Approximately 160
lb of PCBs; 360 lb of Mercury, 300,000 pb of Oil and Grease, 38,000
lb of lead and 140 lb of zinc were removed from the inlet. /more/
