Water Treatment and Testing
Dominion Energy is leading the way in the transition to cleaner energy sources. As part of this transition, we are safely and responsibly monitoring coal ash ponds and landfills using the best science and engineering possible.
We’ve designed a plan - which goes above and beyond U.S. Environmental Protection Agency and Virginia Department of Environmental Quality regulations - to clean up the coal ash ponds. We are using a multi-stage water treatment and filtration process that incorporates state-of-the-art science and engineering and independent, third-party verification. Water is tested multiple times before it ever touches the river, ensuring safety for people, wildlife, and our environment.
We began treating, testing and releasing water from ash ponds at Bremo Power Station in April 2016, at Possum Point Power Station in May 2016, and at Chesterfield Power Station in November 2017.
Note that while the recycling analysis is conducted at Possum Point, at the last remaining pond with ash (Pond D), the company will temporarily cease the release of treated water from the pond. Therefore, water treatment will not be required while this assessment is completed. The current treatment system will be temporarily removed from the site. Therefore there will not be water testing results for Possum Point for the remainder of 2018.
Groundwater monitoring continues around our coal ash ponds and landfills.
