What is the Munimetric score for Massachusetts?

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

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

Massachusetts 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 Massachusetts 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 Massachusetts 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 Massachusetts?

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

Does Munimetric track boil water advisories in Massachusetts?

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 Massachusetts have recent recorded drinking-water violations?

Stored public records show 71 covered systems with recent drinking-water violations, with 1,231 recorded violations across 255 covered systems in the recent 3 years window.

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

Stored contaminant-monitoring summaries are present for 250 covered systems; 142 systems have PFAS detection context in this state summary.

How does Munimetric summarize lead & copper context in Massachusetts?

Stored lead & copper summaries are present for 251 covered systems; 211 systems have violation or action-level context in this state summary.

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

Stored identity records group covered Massachusetts systems by source-water type: Surface water: 145, Groundwater: 110.

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

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

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.

How to read Massachusetts headline composite

Plain-language summary

Massachusetts currently shows an average MISI headline composite of 37.9 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

255 of the community drinking-water systems in Massachusetts are currently scored. Analytics below are calculated from this covered subset only. Covered systems serve approximately 9.9M people.

What the Data Suggests

Massachusetts has 255 scored service markets in the Munimetric coverage set, covering roughly 9.9 million residents in total. At the latest reading, the state-level average lands at 37.9 out of 100, indicating early but meaningful signs of structural stress in aggregate. Roughly 45% of scored markets sit in elevated-stress bands, a substantial concentration.

Across state markets, Operational Stress stands out as the dominant contributor to headline stress (18.1 points average), with Capex Pressure a distant second at 10.9. That pattern suggests a particular kind of pressure — concentrated rather than broadly distributed.

1638 active signals are recorded across state markets. The most prevalent is Climate Hazard Exposure, affecting 251 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 37.9 as of May 19, 2026. Movement since May 17, 2026 is flat.

Munimetric tracks infrastructure stress across 255 community drinking-water systems in Massachusetts, 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 Massachusetts compares nationally.

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

Munimetric tracks infrastructure stress across 255 community drinking-water systems in Massachusetts. 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 Massachusetts 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 Massachusetts?: Munimetric assigns a state-level average MISI score based on the individual scores of all covered community water systems in Massachusetts. 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 Massachusetts face the most infrastructure stress?: The state page ranks the highest-stress systems in Massachusetts by MISI score.
