Tsehootsooi Middle School Water System
Consumer Confidence Report status
Tsehootsooi Middle School 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 4 items for Tsehootsooi Middle School 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.

Tsehootsooi Middle School is one of 77 community water systems in Navajo Nation in the 501 to 3,300 people size category, serving 875 people from groundwater.
As of August 1, 2026, its federal record holds 175 entries between 1996 and 2025, of which 4 remain open; none are health-based.
Of the 175, 154 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, synthetic organic chemicals, and volatile organic chemicals.

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.
