What These Numbers Mean for Nebraska Residents
PFAS in Nebraska Drinking Water
Nebraska's regional PFAS composite is 2.2 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 Nebraska Tap Water
Lead contamination in Nebraska averages 3.6 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 Nebraska
Nebraska's annual average PM2.5 is 7 µg/m³. This meets the EPA annual standard (9 µg/m³) but exceeds the stricter WHO guideline of 5 µg/m³. A HEPA air purifier in sleeping areas is recommended, particularly for children and people with respiratory conditions.
Filtration Recommendations for Nebraska
- Lead concern: Any NSF 53-certified carbon block filter removes lead at the tap. An RO system covers both PFAS and lead. Shop Berkey →
