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.

CAIN ALTO is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 2,416 people from surface water.

As of August 1, 2026, its federal record holds 14 entries between 1983 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
