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.

ESTELLINE is one of 124 community water systems in South Dakota in the 501 to 3,300 people size category, serving 749 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1976 and 2001, all of which EPA lists as closed. Nothing has been added since 2001.
