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.

System facts

System ID (PWSID): MO5024591
System type: Community Water System
Population served: 1,478
Service connections: 913
Ownership: local government
Water source: groundwater (wells)

MO ARK WATER CO is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 1,478 people from groundwater.

As of August 1, 2026, its federal record holds 83 entries between 2008 and 2024, all of which EPA lists as closed.

Of the 83, 78 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 volatile organic chemicals, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
