By State · NY
Based on EPA UCMR 5 testing of 129 public water systems with PFAS detected in New York.
See New York 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 New York
52 New York water systems tested above EPA PFAS limits. The most severe is PEQUENAKONCK ELEMENTARY SCHOOL, where PFOA measured 111.5 ppt — 28× the federal limit.
State context
Industrial context
New York hosts several of the most-publicized US PFAS contamination cases — most prominently the Saint-Gobain Performance Plastics / Honeywell PFOA contamination of Hoosick Falls (2014–present) and the legacy 3M-related contamination of Newburgh's drinking water sourced from Lake Washington near Stewart Air National Guard Base.
Regulatory stance
New York established a 10 ppt drinking-water MCL for PFOA and PFOS in 2020 — ahead of the federal EPA limit. The New York Department of Health operates an active testing and remediation program statewide.
Notable sites
Hoosick Falls, Newburgh, and the village of Petersburgh have all been forced to install treatment systems; multiple lawsuits against Saint-Gobain, 3M, and Honeywell have produced significant settlements.

Test your water
EPA UCMR 5 tested 129 public water systems in New York — 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.
