Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

Teec Nos Pos NTUA is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, serving 752 people from surface water.
As of August 1, 2026, its federal record holds 42 entries between 1996 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 42, 38 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, inorganic chemicals, and the Total Coliform Rules.

What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
