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): OR4100438
System type: Community Water System
Population served: 250
Service connections: 188
Ownership: privately owned
Water source: groundwater (wells)

ROUND LAKE WATER UTILITIES is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 250 people from groundwater.

As of August 1, 2026, its federal record holds 80 entries between 1976 and 2025, all of which EPA lists as closed.

Of the 80, 74 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 synthetic organic chemicals, the Total Coliform Rules, and volatile organic chemicals.
