SWAP - Great Lakes Supplies


About 50 water supplies in Michigan get their source water from the Great Lakes. These supplies typically have one or more intakes in the lakes, ranging from a few hundred feet offshore to many miles offshore, and from just a few feet deep to almost 200 feet deep. These intakes and their source water areas are moderately or highly sensitive to their natural setting. The susceptibility, or risk of contamination, from human activities ranges from moderately low to high.
