Montezuma Creek NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 424 people from groundwater.
As of August 1, 2026, its federal record holds 46 entries between 2008 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 46, 29 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, synthetic organic chemicals, and the Total Coliform Rules.
