Gap-Cedar Ridge NTUA is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, serving 1,125 people from groundwater.

As of August 1, 2026, its federal record holds 46 entries between 2001 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 46, 45 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 synthetic organic chemicals, volatile organic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
