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.

RIVERSIDE CSD is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 333 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 1980 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

The record involves the Miscellaneous Other Rules, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
