What These Numbers Mean for Minnesota Residents
PFAS in Minnesota Drinking Water
Minnesota's regional PFAS composite is 5.4 parts per trillion (ppt), which exceeds the EPA's 2024 enforceable limit of 4 ppt for PFOA and PFOS. Water utilities in Minnesota 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 Minnesota Tap Water
Lead contamination in Minnesota averages 4.2 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 Minnesota
Minnesota'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.
