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): AR0000199
System type: Community Water System
Population served: 712
Service connections: 285
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

DENNING WATERWORKS is one of 376 community water systems in Arkansas in the 501 to 3,300 people size category, serving 712 people from surface water.

As of August 1, 2026, its federal record holds 27 entries between 1994 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 27, 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. The record involves the Total Coliform Rules, the Public Notice Rule and Revised PN Rule, and the Surface Water Treatment Rules.
