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): MO1010001
System type: Community Water System
Population served: 1,635
Service connections: 731
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

ADRIAN PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 1,635 people from surface water.

As of August 1, 2026, its federal record holds 39 entries between 1993 and 2025, of which 2 remain open; none are health-based.

Of the 39, 19 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.
