(WITN) - The City of Jacksonville said Saturday its water is safe to use and consume following ONWASA findings Friday. Although Jacksonville wells are not near the areas where PFAS was discovered, the city said it will test each of its wells for PFAS in the coming weeks as a precaution. The Onslow Water and Sewer Authority said on Friday that PFAS, or perflouroalkyl and polyflouroalkyl substances, had been discovered near two of its wells within a mile of a Marine Corps Base landing field in the Holly Ridge area.
