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.

GUAYANILLA URBANO Water System

Consumer Confidence Report status

GUAYANILLA 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 GUAYANILLA 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): PR0004054
System type: Community Water System
Population served: 7,302
Service connections: 2,735
Ownership: local government
Water source: groundwater (wells)

GUAYANILLA URBANO is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 7,302 people from groundwater.

As of August 1, 2026, its federal record holds 136 entries between 1998 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 136, 131 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, synthetic organic chemicals, and inorganic chemicals.
