St. Clair Power Plant has 4 groundwater monitoring wells, 4 of which have been polluted above federal advisory levels based on samples collected between August 03, 2016 and October 06, 2017. Groundwater at this site contains unsafe levels of lithium, molybdenum, cobalt, arsenic and radium.

Site description

St. Clair Power Plant is a five-unit coal-fired power plant owned by DTE Energy. The plant is located near St Clair River in East China, Michigan, with a total capacity of 1,547 MW. The plant opened in 1953 and is planned for retirement between 2020 and 2022. The two Bottom Ash Basin are constructed such that all CCR is held to approximately 13 feet belowground surface into the native clay‐rich soil. The basins are used for receiving bottom ash and other process flow water from the power plant, which is first sent to the East BAB then to the West BAB through a connecting concrete canal. You can find the industry-reported data here.
