Ash Pond Clean-up Pilot Success in Virginia


An East Coast based coal burning Power Plant* required a water treatment system for a Coal Combustion Residual (CCR) pond to comply with Federal EPA and state regulations. This “Ash Pond” was contaminated with a mix of heavy metals such as lead, copper, thallium, arsenic and selenium. To cap and close the Ash Pond, free and interstitial water, as well as any contact water from rain events, had to be treated to remove these heavy metals prior to discharge to the local river. The General Contractor contracted Envirogen to validate and optimize Envirogen’s treatment approach for this water.
