U.S. Geological Survey scientists created an interactive map to help the public better understand their risk of exposure to PFAS, also known as “forever chemicals.” This interactive tool allows you to view data from a recently published USGS study on PFAS in tap water as well as learn where known PFAS sources are near your community.
