Is CUBUY MAIZALES required to publish a Consumer Confidence Report?

Yes. CUBUY MAIZALES 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 CUBUY MAIZALES’s next Consumer Confidence Report due?

CUBUY MAIZALES’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.

CUBUY MAIZALES Water System

Consumer Confidence Report status

CUBUY MAIZALES 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 5 items for CUBUY MAIZALES that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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): PR0005286
System type: Community Water System
Population served: 595
Service connections: 223
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CUBUY MAIZALES is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 595 people from surface water.

As of August 1, 2026, its federal record holds 82 entries between 1980 and 2024, of which 5 remain open; none are health-based.

Of the 82, 20 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 Total Coliform Rules, the Surface Water Treatment Rules, and the Public Notice Rule and Revised PN Rule.

Common questions

Is CUBUY MAIZALES required to publish a Consumer Confidence Report?: Yes. CUBUY MAIZALES 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 CUBUY MAIZALES’s next Consumer Confidence Report due?: CUBUY MAIZALES’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CUBUY MAIZALES have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 5 items for CUBUY MAIZALES that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.
