Rare Metals NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 72 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 2004 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule, synthetic organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
