CITY OF WILLCOX is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 3,236 people from groundwater.

As of August 1, 2026, its federal record holds 8 entries between 1987 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.

Of the 8, 7 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.

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.
