PFAS+PFOA Health effects:

Exposure to the chemicals, used widely in fire-fighting foams and stain- and water-repellants, is associated with kidney and testicular cancers, low birth weight in babies, thyroid disease, impaired immune function and other health disorders. Mothers and young children may be most vulnerable to the chemicals, which can affect reproductive and developmental health.

Some scientists call PFAS “forever chemicals” because they persist in the environment indefinitely and accumulate in the human body. They are now nearly ubiquitous in human blood serum samples.

Safe levels?

In New York, PFOA had been classified by the state Health Department as an "unspecified organic contaminant" and the enforceable drinking water level of 50,000 parts per trillion had far exceeded the 400-ppt level advised by the U.S. Environmental Protection Agency. Both of those thresholds have since been lowered, in part, due to the outcry that followed the Hoosick Falls' contamination...

70 parts per trillion is the latest health advisory level... for both PFOA and PFAS
