The North Carolina Department of Environment and Natural Resources conducted tests in the Dan River for pH, Specific Conductance, Temperature, and Dissolved Oxygen. They say, “Initial water quality testing performed by DENR staff on site at Duke Energy’s Dan River power plant on Tuesday showed no deviation from normal levels of temperature, pH, dissolved oxygen and conductivity due to the release of water and ash from the facility’s coal ash impoundment…These initial results do NOT mean the water is safe. DENR staff are continuing to sample and test the water. On Tuesday, the first round of water samples were delivered to a lab in Raleigh for further testing for heavy metals, sulfates, nutrients (nitrogen and phosphorus), and total suspended solids.”
