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): MO4010689
System type: Community Water System
Population served: 278
Service connections: 150
Ownership: local government
Water source: groundwater (wells)

RISCO PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 278 people from groundwater.

As of August 1, 2026, its federal record holds 30 entries between 2002 and 2026, of which 3 remain open; none are health-based.

Of the 30, 18 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 Groundwater Rule, synthetic organic chemicals, and the Consumer Confidence Rule.
