How to read Ohio headline composite
Plain-language summary
Ohio currently shows an average MISI headline composite of 28.7 versus a national average of 25.0. 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.

Executive context
What This Page Shows
332 of the community drinking-water systems in Ohio are currently scored. Analytics below are calculated from this covered subset only. Covered systems serve approximately 13.3M people.
What the Data Suggests
Ohio has 332 scored service markets in the Munimetric coverage set, covering roughly 13.3 million residents in total. At the latest reading, the state-level average lands at 28.7 out of 100, indicating early but meaningful signs of structural stress in aggregate. A relatively small share — roughly 8% — currently sit in elevated-stress bands.
Across state markets, Capex Pressure (10.8 points average) and Operational Stress (10.5) are the leading contributors to headline stress. The relatively close spacing suggests pressure is spread across more than one dimension.
1663 active signals are recorded across state markets. The most prevalent is Lead & Copper Rule Risk, affecting 281 markets.
State-level average stress has been relatively steady between recent observation periods, suggesting the current picture reflects persistent conditions rather than a sudden shift.

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 332 community drinking-water systems in Ohio, 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 Ohio compares nationally.
- Which water systems in Ohio face the most infrastructure stress?
- The highest-stress systems in Ohio 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 Ohio compare to other states for drinking water infrastructure risk?

Water Infrastructure in Ohio
Munimetric tracks infrastructure stress across 332 community drinking-water systems in Ohio. Each system receives a Munimetric Infrastructure Stress Index (MISI) score from 0 to 100, calculated across five risk families: Operational Stress, Capex Pressure, Revenue Fragility, Rate Constraint, and Governance Risk. Higher scores indicate more structural stress. Scores are source-backed and deterministic, drawing from EPA SDWA compliance records, American Community Survey demographic and economic data, FEMA National Risk Index hazard profiles, and state financial disclosures.
State-level monitoring shows which systems face the highest structural stress, how Ohio compares against other states nationally, and which monitoring signals are most active across the state. Each individual system profile includes compliance history, score family drivers, peer rankings within population-based cohorts where safeguards pass, and public source context. Full provenance cards and source workbench views remain workflow-gated. Munimetric covers community water systems across all 50 states and territories. This is structural risk research—not a water quality rating, advisory feed, or credit rating. Updated May 2026.
The statewide public-record layer adds drinking-water violation categories, PFAS monitoring summaries where stored, lead and copper context, source-water mix, and official record links across covered systems. These records help explain water-system context alongside infrastructure stress without turning Munimetric into a tap-water safety determination.
- What is the Munimetric score for Ohio?
- Munimetric assigns a state-level average MISI score based on the individual scores of all covered community water systems in Ohio. The state average, band distribution, and market-level rankings are shown on this page. Higher MISI values indicate greater structural stress.
- Which water systems in Ohio face the most infrastructure stress?
- The state page ranks the highest-stress systems in Ohio by MISI score. Stress reflects operational burden, capital gaps, revenue fragility, rate affordability constraints, and governance risk, not a single compliance event. The headline remains a blended structural stress composite rather than a pure physical-condition index. Workflow actions remain reserved for account access.
- How does Ohio compare to other states for drinking water infrastructure risk?
- Ohio is compared against all 50 states and territories using average MISI score, market count, and band distribution. Munimetric tracks nationwide coverage across 9,000+ scored service markets.
- Are there lead pipe or corrosion-related concerns in Ohio water systems?
- Where lead and copper rule compliance data is available from EPA SDWA records, Munimetric factors it into the Operational Stress family score. Specific lead service line inventories vary by system. Individual system profiles contain the most detailed compliance context available.
- Does Munimetric include PFAS monitoring context for Ohio water systems?
- Munimetric summarizes stored PFAS monitoring context where public contaminant-monitoring records are available. Missing PFAS summaries remain missing records, not non-detections, and this public-record layer does not change the MISI score by itself.
- What compliance signals are active in Ohio?
- Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, population decline, income erosion, data staleness, and parent-government fiscal stress across Ohio water systems.
- Does Munimetric track boil water advisories in Ohio?
- 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 that provide context around system reliability over time.
