The Great Lakes Legacy Act was established as a strategy to restore and protect the Great Lakes. “Contaminated sediments at the bottom of the Great Lakes can make fish unsafe to eat for both people and animals. To fix this problem, the Great Lakes Legacy Act authorizes $270 million to clean up contaminated sediments in Areas of Concern.” http://www.epa.gov/glnpo/sediment/legacy/index.html.
I just finished blogging a return comment to ML and decided to post a new blog about it. Here are the results of the first project completed through the Great Lakes Legacy Act. The Black Lagoon in Trenton Channel just South of the Grosse Ile bridge was dredged. This first project was completed in 2005. Ninety thousand cubic yards of silt from the bottom was removed. Lucky me, it was dumped as landfill in a contained disposal site out here in Pt. Mouille somewhere near my home. The site is on the lake, near the game reserves, and wildlife. http://www.epa.gov/glnpo/sediment/legacy/blklagoon/blklagoon.html.
90,000 cubic yards dredged out of the Black Lagoon and dumped near the lake again contains:
160 pounds of PCB’s,
360 lbs. of mercury,
300,000 lbs, of oil and grease,
38,000 lbs. of lead,
140,000 lbs. of zinc.
I did the math and yes the mercury is about 4 /1000th’ per cubic yard, but there will be more. What I want to know is how this stuff just goes away or are we just moving it around? Any civil engineers out there? I would like to know how 300,000 lbs of oil and grease just dissipates somehow? If anyone knows, we would love to hear how we are making this stuff go away for good and what is happening that will prevent more of it. YUK!
Your statistics are as scary as they get! It’s no wonder that there are warnings not to eat the fish from Lake Erie! We used to ice fish there but haven’t been able to for the last 10 years…another telltale sign of destruction.
Ice fishing and ice skating. We used to ice skate on my canal out back. We did it for years. Haven’t had the ice to do that in quite awhile.
