DAN RIVER - Workers at a Duke Energy power plant in North Carolina are scrambling to plug a hole at the bottom of a pond where toxic ash from the coal-fired plant is stored.
The leak was first discovered Sunday. An Associated Press reporter canoed the Dan River on Wednesday and saw gray sludge several inches deep coating the river banks for miles. Twenty miles downstream in Danville, Va., wary fishermen watched gray swirls in the water.
Environmental regulators in North Carolina say they are still awaiting test results to determine if there is any hazard to people or wildlife. Officials in Danville, Va., say they are successfully filtering out contaminates in the drinking water provided to the city.
Danville is located along the Virginia-North Carolina border.
