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.

System facts

System ID (PWSID): MO3031366
System type: Community Water System
Population served: 173
Service connections: 68
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

THE MISSING WELL is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 173 people from surface water.

As of August 1, 2026, its federal record holds 29 entries between 2008 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.

Of the 29, 10 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 Public Notice Rule and Revised PN Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
