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): MT0002974
System type: Community Water System
Population served: 116
Service connections: 10
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

SEVILLE COLONY is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 116 people from surface water.

As of August 1, 2026, its federal record holds 60 entries between 1992 and 2025, all of which EPA lists as closed.

Of the 60, 48 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 Surface Water Treatment Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
