No One Seems to Know Who — or What — Is Poisoning North Carolina Drinking Water Supplies


What seems like a clear case of an energy company polluting people's drinking wells in North Carolina is actually much more complicated, thanks to the state's rock formations.

Last week, North Carolina's Department of Environment and Natural Resources (DENR) sent another round of letters to residents living near the 32 ponds where Duke Energy, the largest electric power company in the country, dumps highly toxic waste known as coal ash produced at its 14 power plants. DENR found that 152 of the 163 private water wells it tested failed to meet state groundwater standards, according to the Associated Press. That's a 93 percent contamination rate.

The tests for contaminates are being conducted on all water wells within 1,000 feet of Duke's coal ash storage ponds, thanks to a 2014 state law passed after a breech at one of the storage ponds sent 39,000 tons of toxic ash into a major river basin — one of the worst coal ash spills in history. Coal ash is what's left over when coal is burned for electricity. It contains toxins such as arsenic, lead, mercury, cadmium, hexavalent chromium, and selenium, all of which can cause an array of illnesses in humans.

The most recent tests conducted by DENR found high levels of lead, vanadium, and hexavalent chromium in the contaminated wells. While Duke told AP it is providing bottled water to "about half a dozen" of the affected residents, Duke Energy spokeswoman Erin Culbert told VICE News that some of the toxic metals may be forming naturally in the groundwater.  READ MORE
