In the first cleanup project made possible by the Great Lakes Legacy Act, EPA and the Michigan Department of Environmental Quality worked together to remove 115,000 cubic yards of polluted sludge from Black Lagoon inlet on the Detroit River. The $9.3 million project cost was shared between EPA (65 percent) and MDEQ’s Clean Michigan Initiative funds (35 percent).
The Black Lagoon lies within the U.S. Fish & Wildlife Service’s Detroit River International Wildlife Refuge, the first international wildlife refuge in North America.
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. The bottom of the dredged 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.
Since the Remediation
