[43] EPA also announced the availability of grant funds to assist small and disadvantaged communities in testing for and treating PFAS contamination in their water ...
PFAS accumulates in the body, which is why EPA set their limits for drinking water at 4 parts per trillion for two common types — PFOA and PFOS — that are phased out of manufacturing but still are present in the environment. Health experts say low doses of the chemicals can build up in the body over time, so even small amounts are a problem.
