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

Kentucky Context
Ohio River basin sees upstream PFAS pressure; older housing carries lead risk.

What These Numbers Mean for Kentucky Residents
PFAS in Kentucky Drinking Water
Kentucky's regional PFAS composite is 3.2 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 Kentucky Tap Water
Lead contamination in Kentucky averages 5.6 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 Kentucky
Kentucky's annual average PM2.5 is 9.2 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 Kentucky
- 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 →
