Illinois Issues Conservative PFAS Health Advisories
Posted by [email protected] on Feb. 19, 2021
Illinois has become the latest state to issue formal Health Advisories for a number of Per- and Polyfluoroalkyl Substances (PFAS). The Health Advisories are for four compounds—Perfluorobutanesulfonic (PFBS) (140,000 parts per trillion “ppt”); Perfluorohexanesulfonic acid (PFHxS) (140 ppt); Perfluorooctanoic acid (PFOA) (2 ppt); and Perfluorohexanoic acid (PFHxA) (560,000 ppt)—and the Illinois Environmental Protection Agency (EPA) was required to issue them after each chemical was detected in at least one public water system in the state.
