In the new EPA regulations, PFOA and PFOS, two of the most well-studied and potentially toxic chemicals, cannot exceed 4 parts per trillion in drinking water. The prior health advisory set a limit ...
PFAS chemicals are found in almost half of all of America's tap water. But there are some steps you can take to try to clean up what comes out of your faucet.
Where will I find PFAS chemicals? In 2023, the U.S. Geological Survey estimated that 45% of America’s tap water contained one or more of the 32 specific PFAS compounds it tested for, including ...
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 ...
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".
The U.S. Environmental Protection Agency has finalized the first federal regulations on toxic "forever chemicals" in drinking water, setting tight limits that essentially require public water ...
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.
Also, 95 public water systems with PFAS levels between the federal standard's 4 parts per trillion and the state's standard of 20 parts per trillion will need to address PFAS for the first time.
