Todahaidekani NTUA Water System
Consumer Confidence Report status
Todahaidekani NTUA must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for Todahaidekani NTUA.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Navajo Nation’s official records. Always confirm current status with Navajo Nation before making decisions based on this information.

Todahaidekani NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 301 people from surface water.
As of August 1, 2026, its federal record holds 90 entries between 2002 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 90, 72 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 synthetic organic chemicals, inorganic chemicals, and volatile organic chemicals.
