CLACKAMAS RIVER WATER is one of 63 community water systems in Oregon in the 10,001 to 100,000 people size category, serving 29,918 people from surface water.
As of August 1, 2026, its federal record holds 51 entries between 1976 and 2025, all of which EPA lists as closed.
Of the 51, 49 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, inorganic chemicals, and the Total Coliform Rules.

When is CLACKAMAS RIVER WATER’s next Consumer Confidence Report due?
- CLACKAMAS RIVER WATER’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.
