MAP: Where water systems reported PFAS contamination. This map shows water systems included in the EPA’s PFAS testing records, as of July 11, 2024. It’s based on boundaries developed by ...
It includes a recommendation that the State of Michigan set advisory limits for PFAS other than PFOA and PFOS, and for the state to develop new drinking water standards "based on weight of evidence and convergence of toxicological and epidemiological data", suggesting that the current national advisory level of 70 ppt for PFOA + PFOS may be too ...
Per- and polyfluoroalkyl substances – also known as PFAs – are widely used, long lasting chemicals found in many consumer, commercial, and industrial products. [2] Breaking down very slowly in the environment, PFAs have been found in water, air, fish, soil, the blood of humans and animals, and food products around the world.
This USGS map shows the number of PFAS detected in tap water samples from select sites across the US. EPA began requiring public water systems to monitor for PFOA and perfluorooctanesulfonic acid (PFOS) in 2012, and published drinking water health advisories, which are non-regulatory technical documents, in 2016.

According to the EPA, well owners should conduct regular testing “for information on the overall quality of the water and whether it contains PFAS.” “Contact your state environmental or ...
Toxic PFAS chemicals are found in drinking water supplies throughout New Mexico. The state's contamination of per- and polyfluoroalkyl substances were largely tied to fire-fighting foam at Air ...
In 2023, the United States EPA proposed "the first (US national) standard to limit (PFAs) in drinking water;" albeit only six of >12,000 such chemicals were addressed. [11] At high temperatures or in a fire, fluoroelastomers decompose and may release hydrogen fluoride. Any residue must be handled using protective equipment. [citation needed]
PFAS in food and your home. Drinking water is not the only way PFAS enters the bloodstream. PFAS is used in nonstick cookware and food packaging to make products resistant to stains, water and ...
