About Maricao, PR

Maricao, PR is a community drinking-water system in Puerto Rico that Munimetric monitors for infrastructure stress. The current MISI score of 15.0 out of 100 places this system in the stable stress band as of 2026-05-24. 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 4,556 people. 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 Maricao, PR?
The current Munimetric Infrastructure Stress Index (MISI) score for Maricao, PR is 15.0 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 Maricao, PR show signs of drinking-water infrastructure stress?
Munimetric monitors structural stress indicators for Maricao, PR 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 Maricao, PR?
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 Maricao, PR 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 Maricao, PR?
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 Maricao, PR?
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 Maricao, PR?
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 Maricao, PR?
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 Maricao, PR?
The MISI score (15.0/100) 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.
