Low Mountain Boarding School BIA Water System

Consumer Confidence Report status

Low Mountain Boarding School BIA 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 2 items for Low Mountain Boarding School BIA 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.

Low Mountain Boarding School BIA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 339 people from groundwater.

As of August 1, 2026, its federal record holds 139 entries between 1996 and 2025, of which 2 remain open; none are health-based.

Of the 139, 135 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 inorganic chemicals.

Common questions

Is Low Mountain Boarding School BIA required to publish a Consumer Confidence Report?

Yes. Low Mountain Boarding School BIA 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 Low Mountain Boarding School BIA’s next Consumer Confidence Report due?

Low Mountain Boarding School BIA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does Low Mountain Boarding School BIA have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show 2 items for Low Mountain Boarding School BIA 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.

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.
