Metals found in wells at NC coal plants

Elevated levels of metals have been found in groundwater near ash basins at all 14 N.C. coal-fired power plants, state regulators say after intensified monitoring.

Duke Energy and Progress Energy sank test wells around their ash ponds several years ago and found tainted groundwater. N.C. officials told them in 2010 to sink more wells, farther from the ponds. That led to results the N.C. Division of Water Quality is now reporting.

Iron, manganese and low pH, all in excess of what the state says is allowable, were found at all 14 plants. Duke and Progress each own seven. Sulfate, dissolved solids and chromium were found at seven plants. Boron was found at six, arsenic at three, and selenium, thallium and antimony at two. Chloride and nickel were each detected at one plant.
