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): IA5225101
System type: Community Water System
Population served: 26,684
Service connections: 95
Ownership: state government
Water source: surface water (rivers, lakes, or reservoirs)

UNIVERSITY WATER SYSTEM is among the 23 largest community water systems in Iowa, serving 26,684 people from surface water.

As of August 1, 2026, its federal record holds 18 entries between 1982 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 18, 17 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, synthetic organic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
