PHOENIX CITY OF is the largest community water system in Arizona, serving 1,695,000 people from surface water.

As of August 1, 2026, its federal record holds 10 entries between 1987 and 2025, all of which EPA lists as closed.

Of the 10, 9 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 volatile organic chemicals.

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.
