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.
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 ...

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 ...
During this process, oxidizing substances are added to PFAS-contaminated water and then the liquid is heated above its critical temperature of 374 degrees Celsius at a pressure of more than 220 bars. The water becomes supercritical, and, in this state, water-repellent substances such as PFASs dissolve much more readily. [227]
