Toxins Leak at NC Coal Ash Dump

Groundwater containing unsafe levels of arsenic apparently leaching from a Duke Energy coal ash dump is still pouring into the Dan River, which is already contaminated from a massive Feb. 2 spill, state officials said.

The state Department of Environment and Natural Resources ordered Duke to stop the flow of contaminated water coming out a pipe that runs under a huge coal ash dump at its Eden, NC, power plant. A nearby pipe at the same dump collapsed without warning two weeks ago, coating the bottom of the Dan River with toxic ash as far as 70 miles downstream.

State regulators expressed concern five days ago the second pipe could fail, triggering a new spill. The water coming out of that pipe contains poisonous arsenic at 14 times the level considered safe for human contact, according to test results released by the state on Tuesday.

“We are ordering Duke Energy to eliminate this unauthorized discharge immediately,” said Tom Reeder, director of the N.C. Division of Water Resources.

Video taken last week by a robot sent inside the 36-inch-wide concrete pipe showed wide gaps between seams through which groundwater is gushing in, likely from the toxic dump above.

Tests on water from the pipe before it goes under the dump showed none of the dangerous contamination detected at the other end. The concrete inside the pipe has heavy stains around the numerous leaks, suggesting the contamination is likely not new.

A state inspector received the video recorded by Duke during a Feb. 11 visit to the site, but did not review it until Thursday. On Friday night, the state agency went public with concerns about the pipe’s structural integrity.

Duke spokeswoman Paige Sheehan quickly issued a statement, downplaying the risk.

“After reviewing the videotape, we determined that no immediate action was necessary,” she said.

In the wake of the initial spill, public health officials issued advisories telling people to avoid contact with the river water and not eat the fish.

Authorities said public drinking water in Danville, Va., and other communities downstream of the Duke plant remain safe.
