Chesterfield Power Station

Chesterfield Power Station has 17 groundwater monitoring wells, 10 of which have been polluted above federal advisory levels based on samples collected between January 07, 2010 and August 04, 2016. Groundwater at this site contains unsafe levels of manganese, arsenic, ammonia and molybdenum.

Dominion Generation's Chesterfield Power Station is located on the James River near the Dutch Gap Conservation Area in Chester, Virginia. The plant was commissioned in 1944, and currently operates two coal ash ponds, the lower and upper ash ponds, which were commissioned in 1964 and 1983, respectively. Closure of the upper ash pond began in 2002. Dominion also operates a metal cleaning waste treatment pond on-site.

According to a 2012 groundwater quality and risk assessment report for the lower ash pond, arsenic contamination around well B-41A is "most likely associated with fly and bottom ash found in the [lower] ash pond."

According to a 2010 dam safety assessment, the lower ash pond has a significant hazard potential rating, indicating that failure of the pond could cause loss of life or appreciable economic damage. The upper ash pond is rated as a low hazard dam.
