HIGH QUALITY H2O is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 200 people from groundwater.

As of August 1, 2026, its federal record holds 33 entries between 1993 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 33, 30 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 HIGH QUALITY H2O required to publish a Consumer Confidence Report?

Yes. HIGH QUALITY H2O 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 HIGH QUALITY H2O’s next Consumer Confidence Report due?

HIGH QUALITY H2O’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does HIGH QUALITY H2O have any open drinking water violations on record?

As of August 1, 2026, EPA's federal records show no open violations for HIGH QUALITY H2O.

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.
