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): ID3140013
System type: Community Water System
Population served: 74,000
Service connections: 25,000
Ownership: local government
Water source: groundwater (wells)

CALDWELL CITY OF is the fourth largest community water system in Idaho, serving 74,000 people from groundwater.

As of August 1, 2026, its federal record holds 164 entries between 2007 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

All 164 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 the Radionuclides and Revised Rad Rule.
