The United States Environmental Protection Agency (EPA) defines PFAS in the Drinking Water Contaminant Candidate List 5 as substances that contain "at least one of the following three structures: R−CF 2 −CF(R')R", where both the −CF 2 − and −CF− moieties are saturated carbons, and none of the R groups can be hydrogen; R−CF 2 −O ...
Remediation of per- and polyfluoroalkyl substances refers to the destruction or removal of per- and polyfluoroalkyl substances (PFASs) from the environment. PFASs are a group of synthetic organofluorine compounds, used in diverse products such as non-stick cookware and firefighting foams, that have attracted great concern as persistent organic pollutants.
In 2023, the United States EPA proposed "the first (US national) standard to limit (PFAs) in drinking water;" albeit only six of >12,000 such chemicals were addressed. [11] At high temperatures or in a fire, fluoroelastomers decompose and may release hydrogen fluoride. Any residue must be handled using protective equipment. [citation needed]
These PFAS would be added to the list of substances identified for consideration in facility assessments and, where necessary, further investigation and cleanup through the corrective action ...
Per-and polyfluoroalkyl substances are found in thousands of products most Americans use or come into contact with daily, such as: Food containers that have PFAs are waterproof and grease-proof ...
A 2018 report to Congress indicated that "at least 126 drinking water systems on or near military bases" were contaminated with PFAS compounds. [ 8 ] [ 9 ] A 2016 study found unsafe [ 10 ] levels of fluorosurfactants in 194 out of 4,864 water supplies in 33 U.S. states.
Flavor-wise and chemical-wise, Spindrift gets some of the highest marks, with 0.19 ppt PFAS, or parts per trillion ("safe" PFAS levels are seen as being below 1 ppt).
In the United States there are no federal drinking water standards for any of the perfluorinated alkylated substances as of late 2020. [21] 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 ...
