Oregon Context
Famously clean Bull Run watershed; episodic wildfire smoke spikes summer PM2.5.

What These Numbers Mean for Oregon Residents
PFAS in Oregon Drinking Water
Oregon'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 Oregon Tap Water
Lead contamination in Oregon averages 4.6 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 Oregon
Oregon's annual average PM2.5 is 7.4 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 Oregon
- Lead concern: Any NSF 53-certified carbon block filter removes lead at the tap. An RO system covers both PFAS and lead. Shop Berkey →
