Wheatfields NTUA Water System
Consumer Confidence Report status
Wheatfields 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 Wheatfields NTUA.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

Wheatfields NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 321 people from groundwater.
As of August 1, 2026, its federal record holds 59 entries between 2008 and 2024, all of which EPA lists as closed.
Of the 59, 56 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, volatile organic chemicals, and the Lead and Copper Rule.

Common questions
Is Wheatfields NTUA required to publish a Consumer Confidence Report?
- Yes. Wheatfields NTUA is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is Wheatfields NTUA’s next Consumer Confidence Report due?
- Wheatfields NTUA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does Wheatfields NTUA have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for Wheatfields NTUA.
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.
