By State · TX
Based on EPA UCMR 5 testing of 1,072 public water systems with PFAS detected in Texas.
See Texas 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 Texas
103 Texas water systems tested above EPA PFAS limits. The most severe is CITY OF GRAND PRAIRIE, where PFOS measured 82.0 ppt — 21× the federal limit.
State context
Industrial context
Texas's PFAS exposure profile is one of the broadest in the US: petrochemical manufacturing across the Houston/Beaumont corridor, AFFF impacts at Joint Base San Antonio, Dyess AFB (Abilene), Sheppard AFB (Wichita Falls), and Naval Air Station Fort Worth, plus legacy semiconductor manufacturing in Austin and Dallas.
Regulatory stance
Texas follows the federal EPA framework. The Texas Commission on Environmental Quality has not promulgated state-level PFAS MCLs.
Notable sites
Communities near Joint Base San Antonio and Dyess AFB have detected PFAS in public water testing; the Lubbock-area former Reese AFB is also on the DoD's PFAS list.

Test your water
EPA UCMR 5 tested 1,072 public water systems in Texas — 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.
