Michigan

State intelligence is assembled from EPA SDWA compliance records, American Community Survey demographic and economic indicators, FEMA NRI hazard exposure profiles, and state-reported financial disclosures. Each service market receives a MISI score (0–100) based on five families: Operational Stress, Capex Pressure, Revenue Fragility, Rate Constraint, and Governance Risk. Scores are deterministic and threshold-based. In v0.1.2, the headline composite remains a blended structural stress measure rather than a pure physical-condition index. A frozen national reference and a 50 percent single-factor cap reduce the dominance of near-universal and very rare factors, while the component bars continue to separate infrastructure, socioeconomic, and observability readings. Peer context is provided by percentile ranking within population-based cohorts.

Munimetric tracks infrastructure stress across 304 community drinking-water systems in Michigan, covering compliance conditions, capital needs, revenue and rate pressure, and governance risk. Use this page to research which systems face the highest structural stress and how Michigan compares nationally.

Which water systems in Michigan face the most infrastructure stress?

The highest-stress systems in Michigan are ranked by MISI score above. Stress reflects operational burden, capital gaps, revenue fragility, rate affordability constraints, and governance risk—not a single compliance event. In v0.1.2, the headline composite remains a blended structural stress measure rather than a pure physical-condition index. A frozen national reference and a 50 percent single-factor cap reduce the dominance of near-universal and very rare factors, while the component bars continue to separate infrastructure, socioeconomic, and observability readings.

How does Michigan compare to other states for drinking water infrastructure risk?

Michigan is compared against all 50 states and territories using average MISI score, market count, and band distribution. The state comparison table above shows where Michigan ranks nationally and how its average score compares.

Are there lead pipe or corrosion-related concerns in Michigan water systems?

Where lead and copper rule compliance data is available from EPA SDWA records, Munimetric factors it into the Operational Stress family. Specific lead service line inventories vary by system. Individual system profiles contain the most detailed compliance context available.

What compliance signals are active in Michigan?

Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, data staleness, and financial stress indicators across Michigan systems. The signal frequency table above summarizes which signals are most prevalent statewide.

Does Munimetric track boil water advisories in Michigan?

Munimetric does not track real-time boil water advisories. For current advisories, contact your local water utility or state drinking water program. Munimetric monitors structural conditions—compliance posture, infrastructure stress, and governance risk—that provide broader context around system reliability.
