The highest PFOA levels in drinking water were found in the Little Hocking water system, with an average concentration of 3.55 parts per billion during 2002–2005. [14] Individuals who drank more tap water, ate locally grown fruits and vegetables, or ate local meat, were all associated with having higher PFOA levels.
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
The United States Environmental Protection Agency has published non-enforceable drinking water health advisories for PFOA and PFOS. [138] [139] In March 2021 EPA announced that it would develop national drinking water standards for PFOA and PFOS. [140] Drinking water utilities are required to monitor PFAS levels and may receive subsidies to do so.
The general population has been exposed to PFOA through massive dumping of C8 waste into the ocean and near the Ohio River Valley. [82] [83] [84] PFOA has been detected in industrial waste, stain-resistant carpets, carpet cleaning liquids, house dust, microwave popcorn bags, water, food and PTFE cookware.
The EPA estimates thousands of PFAS are already in the U.S. environment and can be found in drinking water, soil, food, household items such as carpets and cookware, and more.
Those surveyed had a range of PFOA levels from 0.2-22,412 μg/L, with a median exposure of 28.2 μg/L. [30] These levels were significantly higher than the levels detected in the general American population, which had a median exposure of 3.9μg/L. [30] Results from the study concluded that PFOA exposure was linked to pancreatic cancer and ...
An effective water filtration system will weed out chemicals, pesticides, lead, bacteria and other unhealthy elements. You should at least entertain the idea of abandoning nonstick pans entirely.
A December 2024 study in the journal Chemosphere incorrectly calculated the amount of potentially toxic flame retardants that could be present in some black plastic household products such as ...
