Per- and polyfluoroalkyl substances are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Different organizations use different definitions for PFAS, leading to estimates of between 8,000 and 7 million chemicals within the group.
Called “forever chemicals” because of how long they remain in the human body and environment, perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are a growing health concern.

Many of the chemicals of high concern listed in the report include “well-known bad actors” such as PFAS (or perfluoroalkyl and polyfluoroalkyl substances), phthalates, bisphenols, flame ...
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.
The new standards regulating PFAS, also known as forever chemicals, have been decades in the making, arriving 23 years after Bilott first alerted the U.S. Environmental Protection Agency to PFAS ...
