Shiprock-Rattlesnake-Cudei-Beclabito NTUA is the third largest community water system in Navajo Nation, formerly serving 9,975 people from surface water.
EPA's federal records list this system as inactive in 2007; the record below is historical.
As of August 1, 2026, its federal record holds 9 entries between 1996 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.
Of the 9, 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, the Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.
