Michigan Tap Water Quality: Is It Safe to Drink?

2026 EPA water quality data for 1,371 community water systems serving a combined 7,427,437 people in Michigan. Find your water system to see violations, PFAS results, lead testing, and a safety grade — free.

Michigan is surrounded by the Great Lakes but sources much of its drinking water from groundwater wells. The Flint water crisis of 2014-2019 exposed severe lead contamination from corroded pipes and reshaped national attention on drinking water infrastructure. PFAS contamination from industrial sites, military bases, and foam manufacturing affects communities across the state.
