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

Alaska Context
Remote groundwater is generally clean; PM2.5 spikes in winter inversions and summer wildfire smoke.
Check Your Specific ZIP Code in Alaska
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 Alaska Residents
PFAS in Alaska Drinking Water
Alaska's regional PFAS composite is 1 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 Alaska Tap Water
Lead contamination in Alaska averages 2.4 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 Alaska
Alaska's annual average PM2.5 is 9.5 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.
