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.

Waltham is one of 739 community water systems in Minnesota in the 500 or fewer people size category, serving 157 people from groundwater.

As of August 1, 2026, its federal record holds 3 entries between 2022 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

All 3 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 the Lead and Copper Rule, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
