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.

System type: Community Water System
Population served: 2,221
Service connections: 832
Ownership: local government
Water source: groundwater (wells)

ARENAS is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 2,221 people from groundwater.

As of August 1, 2026, its federal record holds 17 entries between 1996 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 17, 13 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 Total Coliform Rules, and the Consumer Confidence Rule.
