GREENSBORO, N.C.-- The city of Greensboro has launched an investigation after they say elevated levels of perfluorooctane sulfonic acid (PFOS) and related chemical perfluorooctanoic acid (PFOA) were found in samples from a city treatment plant.
The Water Resources Department received samples Monday and reports the results showed the finished water from the Mitchell Water Treatment Plant exceeded the US EPA health advisory level for these two chemicals.
The city says no drinking water regulatory limit was violated and they're working to resolve and address any concerns.
