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): CO0130055
System type: Community Water System
Population served: 350
Service connections: 137
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

IDLEDALE WSD is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 350 people from surface water.

As of August 1, 2026, its federal record holds 64 entries between 1993 and 2025, all of which EPA lists as closed.

Of the 64, 60 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, inorganic chemicals, and volatile organic chemicals.
