Is SANTA ISABEL required to publish a Consumer Confidence Report?

Yes. SANTA ISABEL is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is SANTA ISABEL’s next Consumer Confidence Report due?

SANTA ISABEL’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.

SANTA ISABEL Water System

Consumer Confidence Report status

SANTA ISABEL must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for SANTA ISABEL.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Puerto Rico’s official records. Always confirm current status with Puerto Rico before making decisions based on this information.

System facts

System ID (PWSID): PR0003712
System type: Community Water System
Population served: 3,402
Service connections: 1,274
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

SANTA ISABEL is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 3,402 people from surface water.

As of August 1, 2026, its federal record holds 119 entries between 1992 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 119, 69 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Surface Water Treatment Rules, synthetic organic chemicals, and the Total Coliform Rules.

Common questions

Is SANTA ISABEL required to publish a Consumer Confidence Report?: Yes. SANTA ISABEL is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is SANTA ISABEL’s next Consumer Confidence Report due?: SANTA ISABEL’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does SANTA ISABEL have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for SANTA ISABEL.
What is a Consumer Confidence Report?: A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
