Dzilth-Na-O-Dith-Hle NTUA Water System
Consumer Confidence Report status
Dzilth-Na-O-Dith-Hle 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 1 item for Dzilth-Na-O-Dith-Hle NTUA that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.

Dzilth-Na-O-Dith-Hle NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 462 people from surface water.
As of August 1, 2026, its federal record holds 92 entries between 2002 and 2013, of which 1 remains open; none are health-based.
Of the 92, 91 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, synthetic organic chemicals, and inorganic chemicals.

When is Dzilth-Na-O-Dith-Hle NTUA’s next Consumer Confidence Report due?
- Dzilth-Na-O-Dith-Hle NTUA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

- As of August 1, 2026, EPA's federal records show 1 item for Dzilth-Na-O-Dith-Hle NTUA that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.
