What These Numbers Mean for Arizona Residents

PFAS in Arizona Drinking Water

Arizona's regional PFAS composite is 2.7 parts per trillion (ppt), which is at or below the EPA's 2024 enforceable limit of 4 ppt for PFOA and PFOS. That said, the EPA limit reflects what's technically achievable — the agency's health goal is zero, and any PFAS exposure carries some risk given their persistence in the body.

Lead in Arizona Tap Water

Lead contamination in Arizona averages 1.8 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 Arizona

Arizona's annual average PM2.5 is 10.1 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.
