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): WA5311476
System type: Community Water System
Population served: 71
Service connections: 61
Ownership: privately owned
Water source: groundwater (wells)

WOLF CREEK PROPERTY OWNERS ASSN is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 71 people from groundwater.

As of August 1, 2026, its federal record holds 106 entries between 1998 and 2025, all of which EPA lists as closed.
