NASA is providing extra drinking water for Chincoteague after chemicals used in firefighting foam were found in some wells on the Wallops Flight Facility property that supply the town.

Chincoteague and NASA worked out the arrangement after testing in recent weeks found the chemicals in four of the town’s seven wells, officials said.

Wallops said in a statement that firefighters previously conducted training on the north-central side of the main base with a firefighting foam that contained PFAS compounds.

After the EPA advisory was issued last year, NASA decided to conduct water-quality testing, Wallops spokesman Jeremy Eggers said. The testing was conducted by an independent lab, and the results are being shared with state and federal health agencies, he said. Initial tests of the town’s drinking water detected PFAS but at levels below the advisory set by the EPA. Tests of individual wells detected PFAS in one of four deep wells and three shallow ones. In two of the shallow wells and the deep well, it was detected at a level above the health advisory, according to a NASA statement.
