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 type: Community Water System
Population served: 4,309
Service connections: 1,559
Ownership: local government
Water source: groundwater (wells)

KEWASKUM WATERWORKS is one of 102 community water systems in Wisconsin in the 3,301 to 10,000 people size category, serving 4,309 people from groundwater.

As of August 1, 2026, its federal record holds 56 entries between 1992 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
