On Monday, Maysville switched to Jones County water after high levels of PFAS were detected in the town's well water. Samples analyzed by the NC Per- and Polyfluoroalkyl Substances Testing Network found a combination of perfluorooctanoic acid (PFOA) and perfluorooctanoate sulfonic acid (PFOS) were detected at a level of 103 parts per trillion. PFOS was detected at a concentration greater than 70 ppt, according to a news release from the town. Raw and finished water samples also showed PFOS and the combination of PFOA and PFOS above lifetime Health Advisory Levels established by the Federal Environmental Protection Agency.
Maysville's well water is drawn from the Castle Hayne Aquifer from a depth of 300 ft. About 70,000 gallons of water is used by roughly 450 customers each day. Schemata Brown, the Town Manager of Maysville said in the news release that PFAS is considered an unregulated substance and that samples collected May 7 were the first time the town has tested for PFAS.
Maysville is holding a special session on Thursday, June 13 to discuss the high levels of PFAS. The town is working with government experts to pinpoint a source for the PFAS contamination and figure out how to remove it from the municipal well.
According to the EPA, Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals that are very persistent in the environment and in the human body. In addition to drinking water, PFAS can be found in nonstick cookware, waterproof clothing, and other commercial household products.
