Is LAGO GUAJATACA required to publish a Consumer Confidence Report?

Yes. LAGO GUAJATACA 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 LAGO GUAJATACA’s next Consumer Confidence Report due?

LAGO GUAJATACA’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.

LAGO GUAJATACA Water System

Consumer Confidence Report status

LAGO GUAJATACA 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 LAGO GUAJATACA.

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): PR0003772
System type: Community Water System
Population served: 10,018
Service connections: 3,752
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

LAGO GUAJATACA is one of 61 community water systems in Puerto Rico in the 10,001 to 100,000 people size category, serving 10,018 people from surface water.

As of August 1, 2026, its federal record holds 179 entries between 1993 and 2025, all of which EPA lists as closed.

Of the 179, 90 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, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and volatile organic chemicals.
