Introduction & Rules
Oregon Administrative Rule (OAR) 333-061-0043 requires water suppliers, being the owners or operators of public water systems, to deliver a consumer confidence report (CCR) to customers at community water systems at least once every year.- CCRs must include a summary of key information at the beginning of the report, including but not limited to; contact information for the water supplier, a brief description of any violations, and a note if public notices are included in the report.
- CCRs must include water quality and monitoring information from the previous calendar year and be delivered to customers by July 1st. See
Tools & Resources (below) for help developing a CCR.
- A copy of the CCR must be submitted to the Oregon Health Authority (OHA) by July 11th every year (10 days after the delivery deadline), along with certification identifying how the CCR was delivered to customers and attesting that information contained in the CCR was correct and consistent with compliance monitoring data. See
Tools & Resources for a certification template.
- Water suppliers are encouraged to develop their own dedicated CCR web page so that customers can access past and current reports online.
- Water suppliers must also make a good faith effort to deliver copies of their CCR to consumers who do not receive a water bill.
- Submitting your CCR and certification by email to
dwp.dmce@odhsoha.oregon.gov is preferred and will provide a receipt of delivery to OHA.
- If you don’t have access to email, you may also submit copies of CCRs and certifications by fax to 971-673-0694 or mail to:

2026 Rule Amendments
-
OHA amended CCR rules on January 1, 2026, including changes to the content that must be included in CCRs. For a comparison of the differences between the new and previous requirements, see this
CCR Side-By-Side Comarison. - Beginning on January 1, 2027, the following additional changes will take effect:
- For water systems serving more than 100,000 people, water suppliers must develop a language access plan.
- For water systems serving 10,000 or more people, water suppliers must deliver CCRs twice every year. The first report must be delivered by July 1st and a second report must be delivered by December 31st. If applicable, the second report must include a six-month update for water systems where violations occurred, action levels were exceeded, or where results were received according to the federal Unregulated Contaminant Monitoring Rule (UCMR).

Unregulated Contaminant Monitoring Rule and CCRs
OAR 333-061-0043(3)(l) requires water suppliers to report detections of unregulated contaminants monitored under the Unregulated Contaminant Monitoring Rule (UCMR) in their CCR. Specifically, they must report the average and the range at which the contaminant was detected. Water suppliers should briefly explain in the CCR why they are monitoring for unregulated contaminants, using an explanation such as: "
Unregulated contaminant monitoring helps the U.S. Environmental Protection Agency to determine where certain contaminants occur and whether the Agency should consider regulating those contaminants in the future." Water suppliers may use an alternative explanation in the report if approved by OHA.
Although not required, a water supplier may also choose to add additional information about reference concentrations in order to provide context for their customers around the detection of a particular contaminant. See the following document for reference concentration information from EPA:
UCMR5 Health-Based Reference Values
Additionally,
OAR 333-061-0042(6) requires requires notice to customers at community and non-transient non-community water systems about the availability of the UCMR test results no later than 12 months after the monitoring results are known. Water suppliers can satisfy this requirement for community systems by providing a notice of availability in their annual CCR.
The form and manner of the public notice must meet the requirements for a tier 3 public notice as prescribed in
OAR 333-061-0042(3)(c)(B) and (C). The notice must also identify a person and provide the telephone number to contact for information about the monitoring results. While there is no mandatory language required for notifying customers about the availability of UCMR data, water suppliers may use the language in the following public notice template.
