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.

TOLSTOY is one of 583 community water systems in South Dakota in the 500 or fewer people size category, serving 36 people from surface water.

As of August 1, 2026, its federal record holds 14 entries between 1976 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

The record involves the Total Coliform Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Radionuclides and Revised Rad Rule.
