“Fish caught in the fresh waters of the nation’s streams and rivers and the Great Lakes contain dangerously high levels of PFOS, short for perfluorooctane sulfonic acid, a known synthetic toxin phased out by the federal government, according to a study of data from the US Environmental Protection Agency.

The chemical PFOS is part of a family of manufactured additives known as perfluoroalkyl and polyfluoroalkyl substances, or PFAS, widely used since the 1950s to make consumer products nonstick and resistant to stains, water and grease damage.

Called ‘forever chemicals’ because they fail to break down easily in the environment, PFAS has leached into the nation’s drinking water via public water systems and private wells. The chemicals then accumulate in the bodies of fish, shellfish, livestock, dairy and game animals that people eat, experts say.

‘The levels of PFOS found in freshwater fish often exceeded an astounding 8,000 parts per trillion,’ said study coauthor David Andrews, a senior scientist at Environmental Working Group, the nonprofit environmental health organization that analyzed the data. The report was published Wednesday in the journal Environmental Research.

In comparison, the EPA has allowed only 70 parts per trillion of PFOS in the nation’s drinking water. Due to growing health concerns, in 2022 the EPA recommended the allowable level of PFOS in drinking water be lowered from 70 to 0.02 parts per trillion.”…
