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): AR0000660
System type: Community Water System
Population served: 1,500
Service connections: 529

Water source: surface water (rivers, lakes, or reservoirs)

CASA WATER DEPT is one of 376 community water systems in Arkansas in the 501 to 3,300 people size category, serving 1,500 people from surface water.

As of August 1, 2026, its federal record holds 35 entries between 1991 and 2025, all of which EPA lists as closed.

Of the 35, 6 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
