We launched an updated version of our PFAS Contamination Site Tracker, a publicly available resource that now includes 1,938 sites of known PFAS contamination across US states and territories. In the update, we added over 150 new contamination sites and updated information on existing sites if new testing data were available. In particular, this round of updates has a number of sites in Michigan, New York, Tennessee, and Washington State, among other states. The corresponding interactive PFAS sites and community resources map is now updated and available for viewing!
