Monroe Power Plant has 8 groundwater monitoring wells, 8 of which have been polluted above federal advisory levels based on samples collected between June 03, 2010 and September 19, 2017. Groundwater at this site contains unsafe levels of sulfate, lithium, arsenic and selenium.

Site description

DTE Energy’s Monroe Power Plant is a four-unit coal-fired power plant that has been online since 1971. The plant is located on a 200-acre peninsula that juts into Lake Erie, Michigan. There are two coal ash disposal-related facilities at this site. The first is an 18,500 acre-foot Fly Ash Basin located west of the plant. It was classified as a "significant hazard" dam by the Environmental Protection Agency, though it is regulated as a landfill under Michigan law. The second disposal facility is the Inactive Bottom Ash Basin, which is classified as a low-hazard dam. The Fly Ash Basin is regulated under the CCR rule. You can find the industry-reported data here.
