By State · AK
Based on EPA UCMR 5 testing of 10 public water systems with PFAS detected in Alaska.
See Alaska on the national heatmapState totals reflect systems with at least one PFAS detection in UCMR 5 (the canonical EPA dataset). The 6,151 national total includes ~123 additional systems in US territories and on tribal lands not browsable as state pages.
Most contaminated in Alaska
4 Alaska water systems tested above EPA PFAS limits. The most severe is BARROW UTILITIES & ELEC. COOP., INC. (BU, where PFOS measured 46.3 ppt — 12× the federal limit.
State context
Industrial context
Alaska's PFAS contamination is concentrated near military installations and former DEW Line / Air Force radar stations, where decades of AFFF firefighting foam use saturated groundwater. The state has no significant fluorochemical manufacturing footprint.
Regulatory stance
Alaska's Department of Environmental Conservation has established action levels for PFOA and PFOS in drinking water and operates one of the more active state-level PFAS investigation programs by per-capita scope.
Notable sites
Gustavus, Fairbanks (Eielson AFB), and the former Galena military airfield are all known PFAS-contamination areas with documented well impacts.

Test your water
EPA UCMR 5 tested 10 public water systems in Alaska — but at the utility entry point, not your tap. Aging pipes and indoor plumbing can change what reaches your home, and private wells aren't covered by UCMR 5 at all. To find out what's actually in your water, test it with a certified lab.
