What These Numbers Mean for Alabama Residents

PFAS in Alabama Drinking Water

Alabama'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 Alabama 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 Alabama Tap Water

Lead contamination in Alabama averages 5.4 ppb at the 90th percentile. This is at or above concerning levels. Homes built before 1986 face the highest risk from lead service lines and solder. An NSF 53-certified under-sink filter or reverse osmosis system removes lead at the tap.

PM2.5 Air Quality in Alabama

Alabama's annual average PM2.5 is 9.4 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 Alabama

  • 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 →
