PFAS, or polyfluoroalkyl substances, are a large group of man-made toxic chemicals.
(PFAS are sometimes also called PFCs, or perfluorinated compounds.)
In recent years, some PFAS chemicals have been found at high levels in drinking water systems around the world.
This page provides for communities concerned about PFAS contamination and their drinking water. This work is a collaboration of the Boston University Superfund Research Program and Toxics Action Center, and is supported by independent funding from an anonymous donor.
