Mitchell Power Station has 31 groundwater monitoring wells, 26 of which have been polluted above federal advisory levels based on samples collected between March 28, 2011 and February 22, 2016. Groundwater at this site contains unsafe levels of manganese, sulfate, arsenic, boron, molybdenum, selenium, mercury, cadmium, lead, nitrate and silver.

Site description

FirstEnergy's Mitchell Power Station operated from 1963 until late 2013. The former 370 MW coal-fired power plant is located in Courtney, Pennsylvania along the Monongahela River. Coal ash from the site was disposed of in a 70-acre landfill a mile north of the Power Station from the 1970s until 1982. Two wastewater treatment lagoons were also operated on-site and contained coal ash. Coal ash from the site has also been disposed of in other locations in Southwestern Pennsylvania.

Mitchell Power Station is listed among the U.S. Environmental Protection Agency's potential damage cases, indicating that it has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
