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): WA5326214
System type: Community Water System
Population served: 171
Service connections: 57
Ownership: privately owned
Water source: groundwater (wells)

ALDERDALE WATER ASSN is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 171 people from groundwater.

As of August 1, 2026, its federal record holds 51 entries between 1992 and 2024, all of which EPA lists as closed.

Of the 51, 46 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 inorganic chemicals, the Total Coliform Rules, and the Consumer Confidence Rule.
