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): IA0400900
System type: Community Water System
Population served: 33,000
Service connections: 13,190
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

RATHBUN REGIONAL WATER ASSN (RATHBUN) is among the 18 largest community water systems in Iowa, serving 33,000 people from surface water.

As of August 1, 2026, its federal record holds 35 entries between 1980 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

The record involves volatile organic chemicals, synthetic organic chemicals, and inorganic chemicals.
