After decades of remediation work, two Michigan sites are no longer considered Areas of Concern (AOCs). The U.S. Environmental Protection Agency officially removed Deer Lake in the Lake Superior basin and White Lake in the Lake Michigan Basin from the list of toxic hot spots last week. 


These are the third and fourth U.S. sites to be delisted since a 1987 cleanup agreement with Canada identified areas hit hardest by legacy pollutants like PCBs and mercury. The Oswego River in New York became the first in 2006, and Pennsylvania’s Presque Isle Bay was delisted last year.

The Deer Lake AOC, along the southern shore of Lake Superior on the Upper Peninsula, was listed because of mercury contamination that leached into water flowing through an abandoned iron mine, as well as other pollutants. Mercury contamination in fish—and reproductive problems—also were documented in animals and birds, including bald eagles. 

The remediation efforts included a Great Lakes Restoration Initiative grant for $8 million that helped pay for a project diverting water from Partridge Creek. It previously fed the stream flowing through old mine workings under Ishpeming, which then ran into another creek and into Deer Lake. 

The White Lake AOC was on Lake Michigan in Muskegon County and had been contaminated by pollution—especially organic solvents—from tannery operations, chemical manufacturing and other sources, degrading fish and wildlife habitats.

A $2.5-million grant was used to remove contaminated sediment and restore shoreline, with more than 100,000 cubic yards being removed. Read more

More than two dozen AOCs remain throughout the Great Lakes states. But as many as 10 are targeted for completion in the next five years thanks in part to funding from the Great Lakes Restoration Initiative, which will enter its second phase next year. 

Two of the sites slated for delisting are the Buffalo and Grand Calumet rivers, where IISG’s Caitie McCoy has partnered with federal, state, and local groups under the Great Lakes Legacy Act to connect nearby communities with the remediation and restoration. A big part of this work has focused on integrating environmental cleanup projects into the classroom with place-based curriculum and stewardship projects.
