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.

Service connections: 216
Ownership: local government
Water source: groundwater (wells)

OZARK COUNTY PWSD 1 is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 243 people from groundwater.

As of August 1, 2026, its federal record holds 49 entries between 1992 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
