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): IA8055014
System type: Community Water System
Population served: 1,683
Service connections: 900
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MOUNT AYR WATER TREATMENT PLANT is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 1,683 people from surface water.

As of August 1, 2026, its federal record holds 54 entries between 1982 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

The record involves volatile organic chemicals, inorganic chemicals, and the Former Total Trihalomethane Rule.
