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 ...
Of the 66,000 public drinking water systems impacted by the new standards, the EPA estimates that between 4,100 and 6,700 will eventually have to take action to reduce PFAS contamination.
This US Geological Survey map shows the number of PFAS detected in tap water samples from select sites across the nation. The findings are based on a USGS study of samples taken between 2016 and ...
Other states that have issued PFAS standards include Michigan, New York and Vermont. [79] Between 2016 and 2021 the U.S. Geological Survey (USGS) tested tap water from 716 locations across the United States, finding PFAS levels exceeding the EPA advisories in approximately 75% of samples from urban areas and in approximately 25% of rural areas ...
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.
Prior to the regulations that were just announced, eleven states already had maximum contaminant level regulations in place to limit the amount of PFAS in water. Those states include: Maine ...
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.
