[126] In animals, PFOA is mainly present in the liver, blood, and kidneys. [16]

The U.S. Environmental Protection Agency (EPA) published a non-enforceable health advisory for PFOA in 2016. The agency's health advisory level for the combined concentrations of PFOA and PFOS is 70 parts per trillion (ppt). [22] [23] In June 2020 the State of New Jersey published a drinking water standard for PFOA, the first state to do so.
Many PFAS such as PFOS and PFOA pose health and environmental concerns because they are persistent organic pollutants; they were branded as "forever chemicals" in an article in The Washington Post in 2018. [10] Some have half-lives of over eight years due to a carbon-fluorine bond, one of the strongest in organic chemistry.
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.
