What These Numbers Mean for Vermont Residents
PFAS in Vermont Drinking Water
Vermont's regional PFAS composite is 1.4 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 Vermont Tap Water
Lead contamination in Vermont averages 3 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 Vermont
Vermont's annual average PM2.5 is 6 µg/m³. This is below both the EPA annual standard (9 µg/m³) and approaches the WHO guideline (5 µg/m³). Running a HEPA air purifier indoors can bring indoor air below the WHO threshold even in areas with clean outdoor air.
