Is CLARKS BRANCH WATER ASSOC required to publish a Consumer Confidence Report?

Yes. CLARKS BRANCH WATER ASSOC is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is CLARKS BRANCH WATER ASSOC’s next Consumer Confidence Report due?

CLARKS BRANCH WATER ASSOC’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.

Consumer Confidence Report status

CLARKS BRANCH WATER ASSOC must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for CLARKS BRANCH WATER ASSOC.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Oregon’s official records. Always confirm current status with Oregon before making decisions based on this information.

System facts

System ID (PWSID): OR4100548
System type: Community Water System
Population served: 140
Service connections: 85
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

CLARKS BRANCH WATER ASSOC is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 140 people from surface water.

As of August 1, 2026, its federal record holds 96 entries between 1976 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 96, 94 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 Surface Water Treatment Rules, and the Total Coliform Rules.
