How to read Wyoming headline composite

Plain-language summary

Wyoming currently shows an average MISI headline composite of 20.6 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

25 of the community drinking-water systems in Wyoming are currently scored. Analytics below are calculated from this covered subset only. Covered systems serve approximately 394K people.

What the Data Suggests

Wyoming has 25 scored service markets in the Munimetric coverage set, covering roughly 393,517 residents in total. At the latest reading, the state-level average lands at 20.6 out of 100, indicating limited signs of structural stress in aggregate. No markets currently sit in elevated-stress bands.

Across state markets, Operational Stress (8.7 points average) and Capex Pressure (6.5) are the leading contributors to headline stress. The relatively close spacing suggests pressure is spread across more than one dimension.

111 active signals are recorded across state markets. The most prevalent is Current Drought Severity, affecting 25 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.

This summary is based on structured, source-backed public data and is intended for research and monitoring only. It is not investment advice, a credit opinion, or municipal advisory guidance.

Recent Movement

Latest average MISI is 20.6 as of May 19, 2026. Movement since May 17, 2026 is flat.

Water Infrastructure in Wyoming

Munimetric tracks infrastructure stress across 25 community drinking-water systems in Wyoming. 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 Wyoming 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 Wyoming?
Munimetric assigns a state-level average MISI score based on the individual scores of all covered community water systems in Wyoming. 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 Wyoming face the most infrastructure stress?
The state page ranks the highest-stress systems in Wyoming 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 Wyoming compare to other states for drinking water infrastructure risk?
Wyoming 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 Wyoming 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 Wyoming 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 Wyoming?
Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, population decline, income erosion, data staleness, and parent-government fiscal stress across Wyoming water systems.
Does Munimetric track boil water advisories in Wyoming?
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.
