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.

GUAYAMA URBANO Water System

Consumer Confidence Report status

GUAYAMA URBANO 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 GUAYAMA URBANO.

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): PR0004745
System type: Community Water System
Population served: 37,076
Service connections: 13,886
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

GUAYAMA URBANO is among the 18 largest community water systems in Puerto Rico, serving 37,076 people from surface water.

As of August 1, 2026, its federal record holds 277 entries between 1983 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 277, 191 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 volatile organic chemicals, the Surface Water Treatment Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
