Executive context

What the Data Suggests

Newmarket Water Works, NH is a smaller community water system, serving approximately 5,030 residents. At the latest reading, the system shows limited signs of structural stress.

The score is being driven mainly by Operational Stress, with Capex Pressure contributing at a lower level. The pressure is distributed rather than concentrated in a single dimension.

3 active stress signals are attached to this system. The breadth of active signals, even without concentrated high severity, suggests pressure across more than one dimension.

Within Community · < 25k · Ground, this system ranks around the 11th percentile on measured stress, placing it among the least stressed in its peer group.

Recent score history has been relatively steady, consistent with the system's overall profile.

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.

About Newmarket Water Works, NH

Newmarket Water Works, NH is a community drinking-water system in New Hampshire that Munimetric monitors for infrastructure stress. The current MISI score of 13.4 out of 100 places this system in the stable stress band as of 2026-05-28. The MISI composite reflects five structural risk families: Operational Stress, Capex Pressure, Revenue Fragility, Rate Constraint, and Governance Risk. Higher scores indicate more structural stress.

Data is assembled from EPA SDWA compliance records, American Community Survey demographic and economic indicators, FEMA National Risk Index hazard exposure data, state-reported financial disclosures, and stored public-record water quality context where available. This system serves approximately 5,030 people. The system has 172 recorded compliance violations in the SDWA record. Munimetric does not fabricate data where public records are unavailable. This profile is for structural monitoring and research—not a current-condition determination or credit rating. Updated May 2026.

What is the Munimetric score for Newmarket Water Works, NH?
The current Munimetric Infrastructure Stress Index (MISI) score for Newmarket Water Works, NH is 13.4 out of 100, placing this system in the stable stress band. MISI is a composite of five structural risk families. Higher values indicate more stress. The score is deterministic, source-backed, and updated as new data becomes available.
Does Newmarket Water Works, NH show signs of drinking-water infrastructure stress?
Munimetric monitors structural stress indicators for Newmarket Water Works, NH across operational conditions, capital needs, revenue stability, rate affordability, and governance quality. The current MISI score and active signals shown in this profile reflect the latest available evidence from EPA, ACS, FEMA NRI, and state financial disclosures.
Does Munimetric rate current tap-water conditions for Newmarket Water Works, NH?
No. Munimetric is not a water testing service and does not make current-condition determinations. This profile tracks structural conditions: compliance posture, financial pressure, infrastructure stress, and governance quality. For current water quality testing results, consult the system's Consumer Confidence Report or contact the local water utility.
Has Newmarket Water Works, NH had a boil water advisory?
Munimetric does not track real-time boil water advisories. For current advisory status, contact your local water utility or state drinking water program. This profile tracks structural risk indicators and compliance history that provide long-term context around system reliability.
Are lead pipes or corrosion risk a concern in Newmarket Water Works, NH?
Where EPA SDWA compliance data includes lead and copper rule monitoring, violations, or enforcement actions, that information feeds into the Operational Stress component of the MISI score. Munimetric does not fabricate lead pipe data where public records are silent.
Does Munimetric include PFAS monitoring context for Newmarket Water Works, NH?
Where stored public records include UCMR or contaminant-monitoring summaries, Munimetric displays PFAS monitoring context as public-record evidence. Missing PFAS summaries are treated as missing records, not as non-detections. This context does not change MISI by itself.
What source-water context is available for Newmarket Water Works, NH?
Munimetric displays stored source-water and supply context where public drinking-water identity records are available. Source-water context helps explain treatment and supply exposure, but missing source records remain explicit rather than inferred.
Why might water rates be increasing in Newmarket Water Works, NH?
Rate pressure can reflect capital investment needs, a declining customer base, revenue fragility, affordability constraints, or parent-government fiscal stress. The Rate Constraint and Revenue Fragility score families specifically measure these pressures where data is available from public financial disclosures.
What does the MISI score mean for Newmarket Water Works, NH?
The MISI score (13.4/100) is a composite measure of structural risk across five families: Operational Stress, Capex Pressure, Revenue Fragility, Rate Constraint, and Governance Risk. The headline remains a blended structural stress composite rather than a pure physical-condition index. The current methodology also downweights factors that are nearly universal or very rare in the frozen national reference population, so one common contextual factor does not dominate the headline by itself. Higher scores indicate more structural stress. It is deterministic and source-backed, not a credit rating.
