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. |
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/
