ANTELOPE PEAK DWID Water System
Consumer Confidence Report status
ANTELOPE PEAK DWID 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 ANTELOPE PEAK DWID.
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 Arizona’s official records. Always confirm current status with Arizona before making decisions based on this information.

ANTELOPE PEAK DWID is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, serving 150 people from groundwater.
As of August 1, 2026, its federal record holds 49 entries between 1987 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 49, 40 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, inorganic chemicals, and the Radionuclides and Revised Rad Rule.

Common questions
Is ANTELOPE PEAK DWID required to publish a Consumer Confidence Report?
- Yes. ANTELOPE PEAK DWID 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 ANTELOPE PEAK DWID’s next Consumer Confidence Report due?
- ANTELOPE PEAK DWID’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does ANTELOPE PEAK DWID have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for ANTELOPE PEAK DWID.
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.
