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): OR4100508
System type: Community Water System
Population served: 600
Service connections: 245
Ownership: local government
Water source: groundwater (wells)

MARCOLA WATER DISTRICT is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 600 people from groundwater.

As of August 1, 2026, its federal record holds 66 entries between 1976 and 2026, all of which EPA lists as closed.

Of the 66, 60 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 volatile organic chemicals, the Total Coliform Rules, and synthetic organic chemicals.
