GREENSBORO, N.C. - Almost a week after the City of Greensboro launched an investigation into high levels of two chemicals found in the water it has announced a weekly sampling protocol.
Recently the City discovered the chemicals called perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). These chemicals belong to a family of manmade chemicals that were used for more than 50 years to make products that resist heat, oil, stains, grease, and water. Perfluorinated compounds like PFOS and PFOA are extremely stable and do not breakdown in the environment.
