On Sunday, North Carolina’s environmental agency says it was wrong to declare the arsenic levels in the river safe for people, Al Jazeera reports.
Duke Energy said its results from the Dan River downstream from the company’s power plant in Eden showed traces of arsenic contamination, but at levels considered safe for both people and aquatic life. Those samples were collected two miles downstream from where about 82,000 tons of toxic coal ash has spilled into the river. The spill was discovered a week ago.
Water samples collected yards from the spill site and tested by a certified lab hired by the Waterkeeper Alliance contained hazardous levels of arsenic 10 times higher than Duke’s readings.
