ON THE DAN RIVER, N.C. (AP) — Canoe guide Brian Williams dipped his paddle downstream from where thousands of tons of coal ash has been spewing for days into the Dan River, turning the wooden blade flat to bring up a lump of gray sludge.
On the riverbank, hundreds of workers at a Duke Energy power plant in North Carolina scrambled to plug a hole in a pipe at the bottom of a 27-acre pond where the toxic ash was stored.
Since the leak was first discovered by a security guard Sunday afternoon, Duke estimates up to 82,000 tons of ash mixed with 27 million gallons of contaminated water has spilled into the river. Officials at the nation's largest electricity provider say they cannot provide a timetable for when the leak will be fully contained, though the flow has lessened significantly as the pond has emptied.
An Associated Press reporter canoed downstream of the spill at the Dan River Steam Station and saw gray sludge several inches deep, coating the riverbank for more than two miles. The Dan had crested overnight, leaving a distinctive gray line that contrasted with the brown bank like a dirty ring on a bathtub.
Williams, a program manager with the Dan River Basin Association, worried that the extent of the damage might not be fully understood for years.
"How do you clean this up?" he said, shaking his head as he churned up the ash with his paddle. "Dredge the whole river bottom for miles? You can't clean this up. It's going to go up the food chain, from the filter feeders, to the fish, to the otters and birds and people. Everything in the ecosystem of a river is connected."
Environmental regulators in North Carolina say they are still awaiting test results to determine if there is any hazard to people or wildlife. Coal ash is known to contain a witch's brew of toxic chemicals, including lead, arsenic, mercury and radioactive uranium.
Twenty miles downstream from the spill site and across the state line in Danville, Va., worried fishermen watched ash swirl in the water. A woman dipped her hand into the water and it came out coated slate gray.
Municipal officials in Danville say they are successfully filtering out contaminates in the drinking water for the city of about 43,000 people.
Meanwhile, officials in Virginia Beach, Va., announced they had stopped drawing water from Lake Gaston, a major reservoir fed by the Dan.
Personnel from Duke Energy and an alphabet soup of state and federal agencies, including the U.S. Environmental Protection Agency and U.S. Fish and Wildlife Service, traveled the river in motorboats Wednesday, collecting water and sediment samples. A command center has been set up at the power company's facility in Eden.
