Columbia River Basin Restoration Working Group

About the working group

The Columbia River Basin Restoration Working Group includes over 500 participants from states, Tribes, industries, and non-governmental organizations. The group meets semi-annually to share information on toxics reduction projects and coordinate on monitoring across the Columbia River Basin.

Working group meetings

The working group meets two times each year, led and coordinated by EPA. Meetings are open to the public and anyone may participate.

Next meeting

April 22-23, 2026
Portland, Oregon (in person + hybrid)
Visit our registration page for meeting details and draft agenda. Registration deadline is April 6, 2026. Registration is free and open to all.

Note: There will be a hybrid meeting option available, but our priority is facilitating meaningful engagement for those attending in person. Details for how to attend the hybrid sessions will be provided closer to the meeting dates.

Toxics monitoring dashboard

The Columbia River Basin Toxics Monitoring Dashboard visualizes the data collected in the Toxics Monitoring Project Tracking Matrix. Together they are intended to advance the broad understanding of toxics monitoring efforts in the Basin (who’s doing what, where, when, and how), help facilitate coordination and collaboration among toxics monitoring projects, and assist with identifying information gaps.
