Is Dilkon-Indian Wells-Greasewood-White Cone NTUA required to publish a Consumer Confidence Report?

Yes. Dilkon-Indian Wells-Greasewood-White Cone 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 Dilkon-Indian Wells-Greasewood-White Cone NTUA’s next Consumer Confidence Report due?

Dilkon-Indian Wells-Greasewood-White Cone NTUA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

Consumer Confidence Report status

Dilkon-Indian Wells-Greasewood-White Cone 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 Dilkon-Indian Wells-Greasewood-White Cone 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.

System facts

System ID (PWSID): NN0400342
System type: Community Water System
Population served: 4,986
Service connections: 1,458
Ownership: Native American tribal
Water source: groundwater (wells)

Dilkon-Indian Wells-Greasewood-White Cone NTUA is among the 7 largest community water systems in Navajo Nation, serving 4,986 people from groundwater.

As of August 1, 2026, its federal record holds 111 entries between 2003 and 2024, of which 1 remains open; none are health-based.

Of the 111, 43 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and volatile organic chemicals.

Common questions

Is Dilkon-Indian Wells-Greasewood-White Cone NTUA required to publish a Consumer Confidence Report?: Yes. Dilkon-Indian Wells-Greasewood-White Cone 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 Dilkon-Indian Wells-Greasewood-White Cone NTUA’s next Consumer Confidence Report due?: Dilkon-Indian Wells-Greasewood-White Cone NTUA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does Dilkon-Indian Wells-Greasewood-White Cone NTUA have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for Dilkon-Indian Wells-Greasewood-White Cone 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.
