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.

EL ROSARIO Water System

Consumer Confidence Report status

EL ROSARIO 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 EL ROSARIO.

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): PR0003423
System type: Community Water System
Population served: 2,374
Service connections: 889
Ownership: local government
Water source: groundwater (wells)

EL ROSARIO is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 2,374 people from groundwater.

As of August 1, 2026, its federal record holds 62 entries between 1997 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 62, 52 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 the Total Coliform Rules.
