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.

Water source: groundwater (wells)

CENTENNIAL PARK DWID is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 1,578 people from groundwater.

As of August 1, 2026, its federal record holds 22 entries between 1987 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

The record involves volatile organic chemicals, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
