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.

System facts

System ID (PWSID): AZ0415058
System type: Community Water System
Population served: 559
Service connections: 254
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

EPCOR - HOLIDAY HARBOR is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 559 people from surface water.

As of August 1, 2026, its federal record holds 57 entries between 1981 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 57, 54 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 inorganic chemicals, the Surface Water Treatment Rules, and synthetic organic chemicals.
