Per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," continue to pose one of the greatest challenges to water treatment and environmental remediation industries. Recently, the US EPA announced shockingly low interim drinking water health advisory levels for PFAS compounds PFOA and PFOS: over 1000 times lower than previous levels. What is US EPA's reasoning for the stringent limits, how should water providers be reacting to these new measures, and what should we expect for the future?

Heather Lanza, PFAS health risk expert, has a passion for solving emerging environmental issues and battling chemical exposure health effects. Her work has spanned across the U.S. and internationally, from Australia, to Ireland, to Canada, as Heather conducts health assessments and samples environmental media in the fight against these pervasive chemicals. She shares her insights regarding maximum contaminant levels, the link between PFAS exposure and vaccine effectiveness, and the best ways utilities should be handling public communications.

PFAS regulations are complicated, and each set of state regulations looks a little bit different. To help you understand what PFAS regulations affect your state, CDM Smith has put together an interactive map with the latest details. Check it out here: [ Ссылка ]
