As Duke Energy and environmentalists have debated the safety of private wells near coal ash ponds, they've disagreed about the source of a carcinogen called hexavalent chromium. Scientists at Duke University figured out how to identify the chemical’s source. Conclusions from the study of 376 private wells say coal ash likely isn't to blame. WFAE's David Boraks talked with the study's lead author, Avner Vengosh about his research and recommendations.
