Dominion Virginia Power is offering to pay the costs of connecting residents who live near its Possum Point power plant to Prince William County’s public water system, after tests in nearby wells showed elevated levels of nickel, boron and other contaminants.

The utility, which has been working to rid the power station of coal ash pollution inside five retention ponds, plans to meet with county officials this week about the offer, company spokesman Robert Richardson said Monday.

Richardson said Dominion sent letters last week to 35 properties along the edge of the Possum Point plant that provided details about the contamination inside company-owned wells located near the retention ponds.

Most of those residents are already connected to the county water system, he said. But between eight and 11 homes along Possum Point Road rely on their own wells for drinking water.

Richardson said the water was tested in September at the behest of the state Department of Environmental Quality, which is preparing to hold public hearings in January on an application by Dominion to seal the coal ash at Possum Point instead of carting it away.

The company has faced legal challenges to its cleanup efforts, but those efforts have gone nowhere.

Richardson said the elevated levels of contaminants inside the plant’s wells still fall below state standards for safe drinking water. But, he added, the company wants to erase any concerns about public safety.

“We want people to feel good about their drinking water,” he said.
