In Warminster and surrounding towns in eastern Pennsylvania, and at other sites around the United States, the foams once used routinely in firefighting training at military bases contained per-and polyfluoroalkyl substances, or PFAS.
That was before testing showed it had some of the highest levels of the toxic compounds of any public water system in the U.S. “You all made me out to be a liar,” Hagey, general water and sewer manager in the eastern Pennsylvania town of Warminster, told Environmental Protection Agency officials at a hearing last month.
The meeting drew residents and officials from Horsham and other affected towns in eastern Pennsylvania, and officials from some of the other dozens of states dealing with the same contaminants.
At “community engagement sessions” around the country this summer like the one in Horsham, residents and state, local and military officials are demanding that the EPA act quickly — and decisively — to clean up local water systems testing positive for dangerous levels of the chemicals, perfluoroalkyl and polyfluoroalkyl substances, or PFAS.
Earlier this year, federal toxicologists decided that even the EPA’s 2016 advisory levels for the two phased-out versions of the compound were several times too high for safety.
In Horsham and surrounding towns in eastern Pennsylvania, and at other sites around the United States, the foams once used routinely in firefighting training at military bases contained PFAS.
The chemical industry says it believes the versions of the nonstick, stain-resistant compounds in use now are safe, in part because they don’t stay in the body as long as older versions.
In Delaware, National Guard troops handed out water after high levels of PFAS were found in a town’s water supply.
“If the risk appears to be high, and you’ve got it every place, then you’ve got a different level” of danger and urgency, Clough said.
In 2005, under President George W. Bush, the EPA and DuPont settled an EPA complaint that the chemical company knew at least by the mid-1980s that the early PFAS compound posed a substantial risk to human health.
