Snapshot

Merom Generating Station has 37 groundwater monitoring wells, 24 of which have been polluted above federal advisory levels based on samples collected between May 26, 2010 and September 05, 2017. Groundwater at this site contains unsafe levels of cadmium, lithium, sulfate, boron, manganese, arsenic, cobalt, chromium, lead, barium, beryllium and fluoride.

Site description

Merom Generating Station is a coal-fired plant located near Sullivan, Indiana and the Wabash River. The plant sits on the banks of an unnamed lake. Opened since 1982, the station operates two generating units with the total capacity of 1,080 MW. There are three coal ash landfills at the station: Inactive Area 1, Active Area 2, and Area 3. The landfills were designed with either natural cohesive soil barriers or a compacted clay liner. Area 1 and Area 2 landfills were not equipped with a leachate collection system. Area 3 was planned for closure in October, 2016. You can find the industry-reported data here. For more information on the Merom Generating Station, see EIP’s 2019 National Coal Ash Report.
