Sheepsprings North NTUA is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, formerly serving 743 people from groundwater.
EPA's federal records list this system as inactive in 1970; the record below is historical.
As of August 1, 2026, its federal record holds 7 entries between 2002 and 2003, all of which EPA lists as closed. Nothing has been added since 2003.
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 Total Coliform Rules and inorganic chemicals.
