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): MO5010446
System type: Community Water System
Population served: 4,500
Service connections: 2,063
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

LAMAR PWS is one of 140 community water systems in Missouri in the 3,301 to 10,000 people size category, serving 4,500 people from surface water.

As of August 1, 2026, its federal record holds 51 entries between 1989 and 2024, all of which EPA lists as closed.

Of the 51, 22 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
