What is the Munimetric score for Green Bay Waterworks, WI?

The current Munimetric Infrastructure Stress Index (MISI) score for Green Bay Waterworks, WI is 26.4 out of 100, placing this system in the watch 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 Green Bay Waterworks, WI show signs of drinking-water infrastructure stress?

Munimetric monitors structural stress indicators for Green Bay Waterworks, WI 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 Green Bay Waterworks, WI?

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 Green Bay Waterworks, WI 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 Green Bay Waterworks, WI?

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 Green Bay Waterworks, WI?

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 Green Bay Waterworks, WI?

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 Green Bay Waterworks, WI?

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 Green Bay Waterworks, WI?

The MISI score (26.4/100) 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.

Executive context

What the Data Suggests

Green Bay Waterworks, WI's drinking-water system serves about 107,369 residents, making it a mid-size system within the coverage universe. At the latest reading, Munimetric flags the system as showing early but meaningful signs of structural stress.

The score is being driven mainly by Capex Pressure, which is at the top of its range in the model, with Operational Stress adding further pressure. In other words, Capex Pressure is doing most of the heavy lifting in the headline score.

3 active stress signals are attached to this system, including 3 at high severity. Multiple high-severity signals suggest the score is not being lifted by background noise alone.

Within Community · 100k–250k · Surface, this system ranks around the 26th percentile on measured stress, placing it below typical peer-group stress levels.

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.
