What is the Munimetric score for Arkansas?

Munimetric assigns a state-level average MISI score based on the individual scores of all covered community water systems in Arkansas. 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 Arkansas face the most infrastructure stress?

The state page ranks the highest-stress systems in Arkansas 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 Arkansas compare to other states for drinking water infrastructure risk?

Arkansas 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 Arkansas 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 Arkansas 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 Arkansas?

Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, population decline, income erosion, data staleness, and parent-government fiscal stress across Arkansas water systems.

Does Munimetric track boil water advisories in Arkansas?

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.

How many covered systems in Arkansas have recent recorded drinking-water violations?

Stored public records show 38 covered systems with recent drinking-water violations, with 241 recorded violations across 158 covered systems in the recent 3 years window.

How does Munimetric summarize PFAS public-record context in Arkansas?

Stored contaminant-monitoring summaries are present for 148 covered systems; 49 systems have PFAS detection context in this state summary.

How does Munimetric summarize lead & copper context in Arkansas?

Stored lead & copper summaries are present for 158 covered systems; 74 systems have violation or action-level context in this state summary.

What source-water types are represented across covered Arkansas systems?

Stored identity records group covered Arkansas systems by source-water type: Surface water: 104, Groundwater: 54.

Where can I find official drinking-water records for Arkansas?

The Official records drawer lists Public drinking-water profile, Contaminant monitoring records links where currently available for Arkansas.

Is this a real-time statewide tap-water condition rating?

No. This is not a real-time tap-water condition determination. Munimetric summarizes stored public-record context for research and navigation, and this layer does not change MISI.

State interpretation guide

How to read Arkansas headline composite

Plain-language summary

Arkansas currently shows an average MISI headline composite of 22.7 versus a national average of 24.5. 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.

Why this page stands out

158 scored systems are included in this state view, with explicit confidence and source-backed context.
State posture is benchmarked against national averages, not evaluated in isolation.
Top system links below connect state-level findings directly to profile-level diagnostics.

What to do next

Executive context

What This Page Shows

158 of the community drinking-water systems in Arkansas are currently scored. Analytics below are calculated from this covered subset only. Covered systems serve approximately 2.6M people.

What the Data Suggests

Arkansas has 158 scored service markets in the Munimetric coverage set, covering roughly 2.6 million residents in total. At the latest reading, the state-level average lands at 22.7 out of 100, indicating early but meaningful signs of structural stress in aggregate. A relatively small share — roughly 6% — currently sit in elevated-stress bands.

Across state markets, Capex Pressure (8.8 points average) and Operational Stress (8.7) are the leading contributors to headline stress. The relatively close spacing suggests pressure is spread across more than one dimension.

704 active signals are recorded across state markets. The most prevalent is Climate Hazard Exposure, affecting 134 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 22.7 as of Jul 11, 2026. Movement since Jul 10, 2026 is flat.

Munimetric tracks infrastructure stress across 158 community drinking-water systems in Arkansas, 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 Arkansas compares nationally.

Which water systems in Arkansas face the most infrastructure stress?: The highest-stress systems in Arkansas 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 Arkansas compare to other states for drinking water infrastructure risk?: Arkansas is compared against all 50 states and territories using average MISI score, market count, and band distribution. The state comparison table above shows where Arkansas ranks nationally and how its average score compares.
Are there lead pipe or corrosion-related concerns in Arkansas 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 Arkansas?: Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, data staleness, and financial stress indicators across Arkansas systems. The signal frequency table above summarizes which signals are most prevalent statewide.
Does Munimetric track boil water advisories in Arkansas?: 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.

Water Infrastructure in Arkansas

Munimetric tracks infrastructure stress across 158 community drinking-water systems in Arkansas. 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 Arkansas 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 Arkansas?: Munimetric assigns a state-level average MISI score based on the individual scores of all covered community water systems in Arkansas. 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 Arkansas face the most infrastructure stress?: The state page ranks the highest-stress systems in Arkansas 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 Arkansas compare to other states for drinking water infrastructure risk?: Arkansas 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 Arkansas 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 Arkansas 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 Arkansas?: Munimetric tracks signals such as compliance escalation, monitoring and reporting failures, population decline, income erosion, data staleness, and parent-government fiscal stress across Arkansas water systems.
Does Munimetric track boil water advisories in Arkansas?: 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.
