Per- and polyfluoroalkyl substances ( PFAS [1] or PFASs [2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make fluoropolymer coatings and products ...
Following initial discoveries of groundwater contamination in 2002, the Minnesota Department of Health conducted numerous studies –concluding in 2008, 2010, and 2014 – on the level of PFAs found in the bloodstreams of exposed residents. On February 20, 2018, the state of Minnesota settled its lawsuit against 3M in exchange for $850 million.
In 2018, Elsie Sunderland of Harvard's School of Public Health, said the chemical industry's practice of manufacturing ever-increasing numbers of new PFAS compounds − even as they phase out old ...

Perfluorohexanesulfonic acid ( PFHxS) ( conjugate base perfluorohexanesulfonate) is a synthetic chemical compound. It is one of many compounds collectively known as per- and polyfluoroalkyl substances (PFASs). It is an anionic fluorosurfactant and a persistent organic pollutant with bioaccumulative properties.
Feb. 3—SANTA FE — The U.S. Environmental Protection Agency on Thursday announced two proposed rules "to ensure that certain per- and polyfluoroalkyl substances (PFAS), also known as 'forever ...
March 2018 The United States Department of Defense's (DoD)'s report to Congress said that test that they conducted showed that the amount of PFAS chemicals in water supplies near 126 DoD facilities, "exceeded the current safety guidelines". The DoD has "used foam containing" PFAS chemicals "in exercises at bases across the country".
In an effort to combat PFAS or "forever chemicals" found in the drinking water of communities throughout the country, the Environmental Protection Agency received $1 billion in federal funding.
