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): MT0000270
System type: Community Water System
Population served: 6,339
Service connections: 2,797
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

LAUREL MUNICIPAL WATER SYSTEM is among the 19 largest community water systems in Montana, serving 6,339 people from surface water.

As of August 1, 2026, its federal record holds 44 entries between 1993 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 44, 39 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, inorganic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
