CITY OF SHOW LOW is one of 67 community water systems in Arizona in the 10,001 to 100,000 people size category, serving 17,139 people from groundwater.

As of August 1, 2026, its federal record holds 33 entries between 1980 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

All 33 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 volatile organic chemicals, inorganic chemicals, and the Total Coliform Rules.
