Michigan Water Systems
1,434 community water systems in Michigan, ranked by violation count. Data from EPA Safe Drinking Water Information System (SDWIS).
Michigan community water systems are regulated by the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act; each utility files compliance results with the state's primacy agency and, for federally listed contaminants, with the U.S. Environmental Protection Agency directly. PlainEnviro's health-based SDWIS extract above counts health-based exceedances only -- monitoring and reporting violations are not present in these figures.
Violation counts reflect both infrastructure realities and reporting diligence, a state with more small rural systems will accumulate more monitoring-type violations without necessarily delivering worse water. Health-based violations are the stronger safety signal. A past violation does not itself indicate current unsafe water; utilities must notify customers, remediate, and publish an annual Consumer Confidence Report. All numbers below draw directly from the federal SDWIS record.
