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 facts

System ID (PWSID): PR0003573
System type: Community Water System
Population served: 3,853
Service connections: 1,443
Ownership: local government
Water source: groundwater (wells)

RAYO is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 3,853 people from groundwater.

As of August 1, 2026, its federal record holds 24 entries between 1980 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 24, 14 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 inorganic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
