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): IA0800601
System type: Community Water System
Population served: 160
Service connections: 64
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

MAPLE GROVE MHC is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 160 people from surface water.

As of August 1, 2026, its federal record holds 20 entries between 1980 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

The record involves inorganic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
