PFAS Forever Chemical Contamination
Per- and polyfluoroalkyl substances (PFAS) are detected in the blood of 99 percent of Americans, including newborns. 176 million Americans are exposed through drinking water. PFAS are associated with cancers, immune suppression, thyroid disorders, reproductive harm, and reduced vaccine effectiveness. They persist in the environment essentially forever, with no known natural degradation pathway. While some regulation is advancing, the US EPA is rolling back limits on several PFAS compounds. No method exists to remove PFAS from the human body. Cleanup costs potentially reach into the trillions.

Claims
PFAS are present in the blood of essentially all Americans and persist in the environment indefinitely, with no known natural degradation pathway.
CDC NHANES biomonitoring data confirms near-universal PFAS detection in US blood samples. The carbon-fluorine bond stability that defines PFAS is established chemistry. No known environmental degradation pathway has been identified in peer-reviewed literature. Evidence Level A.
