ORO VALLEY WATER UTILITY is among the 25 largest community water systems in Arizona, serving 42,316 people from groundwater.

As of August 1, 2026, its federal record holds 421 entries between 1980 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 421, 420 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 volatile organic chemicals, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.

Yes. ORO VALLEY WATER UTILITY 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 ORO VALLEY WATER UTILITY’s next Consumer Confidence Report due?

ORO VALLEY WATER UTILITY’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

Does ORO VALLEY WATER UTILITY have any open drinking water violations on record?

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.
