Red Valley North NTUA is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, serving 756 people from groundwater.
As of August 1, 2026, its federal record holds 29 entries between 2005 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 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 volatile organic chemicals, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
