Michigan Drinking Water Alerts — EPA & State Boil-Water Notices
Drinking water tracks Active boil-water advisories, lead-action exceedances, and EPA Safe Drinking Water Act violations for Michigan public water systems. The reading is aggregated by Michigan Gateway from EPA SDWIS · EGLE Drinking Water Division, an authoritative public source, and refreshed automatically throughout the day.
For Michigan residents this indicator is one of several environmental-hazard signals that inform day-to-day decisions — from whether it's safe to be outdoors to whether a specific community needs additional attention. Combined with the other environment indicators listed at the bottom of this page, it helps residents, journalists, and county officials build a fuller picture of current conditions in Michigan.
The current reading for this indicator updates live on the

Michigan has 1,400+ public water systems serving roughly 80% of the state population. Federal Safe Drinking Water Act standards cover lead, copper, bacteria, nitrate, arsenic, and disinfection by-products. The Flint water crisis (2014–15) and ongoing PFAS issues have made Michigan one of the most actively monitored states in the country.
