What These Numbers Mean for Michigan Residents

PFAS in Michigan Drinking Water

Michigan's regional PFAS composite is 5.8 parts per trillion (ppt), which exceeds the EPA's 2024 enforceable limit of 4 ppt for PFOA and PFOS. Water utilities in Michigan 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 Michigan Tap Water

Lead contamination in Michigan averages 8.4 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 Michigan

Michigan's annual average PM2.5 is 8.6 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.
