Possum Point Power Station

Possum Point Power Station has 36 groundwater monitoring wells, 18 of which have been polluted above federal advisory levels based on samples collected between April 12, 2010 and August 29, 2019. Groundwater at this site contains unsafe levels of cobalt, manganese, arsenic, nickel, cadmium, boron and radium.

Dominion Generation's Possum Point Power Station is a natural gas and oil plant located along the Potomac River in Dumfries, Virginia. The plant was commissioned in 1948 and has the total capacity of 613 MW. The plant has one active dual fired combined-cycle unit. Units 1 through 5 have been retired, including two coal-fired, two natural gas, and one oil-fired unit. The station used to store byproducts from combustion of coal including fly ash and bottom ash in five surface impoundments. No new CCR has been generated or placed in these impoundments since the conversion to gas‐ fired units in 2003. There are three disposal areas regulated under the CCR rule: Ponds ABC, Pond D, and Pond E. Ash from Ponds ABC and Pond E, both inactive surface impoundments, has been removed and placed in Pond D. Possum Point is among the U.S. Environmental Protection Agency's list of potential damage cases, indicating that coal ash disposal at the site has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
