Water & Air Quality in Texas
Regional composite data for PFAS, lead, and PM2.5 in Texas. Values are derived from EPA UCMR 5, EWG Tap Water Database, and AirNow annual averages. Check your specific ZIP code below for localized results.

Texas Context
Petrochemical Gulf Coast drives PM2.5; PFAS detections in eastern Texas utilities.

State averages mask wide local variation. Your ZIP code may be significantly cleaner or more contaminated than the state composite — especially near industrial sites, military bases, or older housing stock.

What These Numbers Mean for Texas Residents
PFAS in Texas Drinking Water
Texas's regional PFAS composite is 4.2 parts per trillion (ppt), which exceeds the EPA's 2024 enforceable limit of 4 ppt for PFOA and PFOS. Water utilities in Texas have until 2029 to comply. In the interim, a point-of-use reverse osmosis filter (NSF 58 certified) removes 95%+ of PFAS at the tap.
Lead in Texas Tap Water
Lead contamination in Texas averages 3.4 ppb at the 90th percentile. This is within the EPA's action level but above the zero health goal. Lead pipes in pre-1986 homes remain the primary risk factor — consider an NSF 53-certified filter as a precaution.
PM2.5 Air Quality in Texas
Texas's annual average PM2.5 is 9.2 µg/m³. This exceeds the EPA annual standard of 9 µg/m³. Long-term PM2.5 at this level is associated with increased cardiovascular mortality (Pope & Dockery). A high-CADR HEPA purifier in your main living and sleeping areas is strongly recommended.
Filtration Recommendations for Texas
- PFAS concern: AquaTru Countertop RO (NSF 58) removes >95% of PFAS — the most effective countertop option. Shop AquaTru →
- Lead concern: Any NSF 53-certified carbon block filter removes lead at the tap. An RO system covers both PFAS and lead. Shop Berkey →
- PM2.5 concern: Blueair Blue Pure 211i Max (HEPA, 635 sq ft) is the top value pick for PM2.5 reduction. Shop Blueair →
