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.
Some, but not all, studies in humans with PFAS exposure have shown that certain PFAS may affect growth, learning, and behavior of infants and older children, lower a woman's chance of getting pregnant, interfere with the body's natural hormones, increase cholesterol levels, affect the immune system, and increase the risk of cancer."

[11] [16] [17] [6] Since PFAS compounds are highly mobile, they are readily absorbed through human skin and through tear ducts, and such products on lips are often unwittingly ingested. [18] Due to the large number of PFAS, it is challenging to study and assess the potential human health and environmental risks; more research is necessary and ...
The EPA’s proposed drinking water standards would remove six PFAS or “forever chemicals” from water. Here’s what PFAS really are—and how they can cause harm.
PFAS, or per- and polyfluorinated substances, were invented in the late 1930s and have been used to make coatings and products that resist heat, grease, stains, oil and water, according to the ...
As a result, the plant wasn’t built for PFAS removal. The facility is removing some trace amounts of PFAS arriving from Worcester’s water sources, said Divoll. Worcester’s water is supplied ...
Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS). It is an anthropogenic (man-made) fluorosurfactant, now regarded as a global pollutant.
On Wednesday the FDA announced certain grease-proofing substances containing per and polyfluoroalkyl substances, or PFAS, would no longer be sold for use in food packaging in the U.S.
