As of August 1, 2026, EPA's federal records show 4 items for Red Mesa NTUA that are 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.

Red Mesa NTUA is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, serving 1,023 people from surface water.

As of August 1, 2026, its federal record holds 55 entries between 2004 and 2024, of which 4 remain open; none are health-based.

Of the 55, 32 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 Public Notice Rule and Revised PN Rule.

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.
