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.

CIMARRONA Water System

Consumer Confidence Report status

CIMARRONA 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 CIMARRONA.

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): PR0003832
System type: Community Water System
Population served: 2,411
Service connections: 903
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CIMARRONA is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 2,411 people from surface water.

As of August 1, 2026, its federal record holds 45 entries between 2004 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 45, 41 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 synthetic organic chemicals, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
