EPA invites you to attend an online presentation about our work at the Upper Columbia River, and a summary of our human health risk assessment.

We will hold webinars on June 10 and July 15, to provide information about our work at the site, and invite input from community members. EPA is committed to providing the affected community with information about our work and an opportunity to provide meaningful input on decisions that affect them.

The webinars will provide an overview of:

  • Background on the Upper Columbia River study.

  • What a human health risk assessment is.

  • How EPA uses the risk assessment.

  • Results of the draft Upper Columbia River Study area human health risk assessment.

Each of the webinars will provide the same information. If you would like to attend either of the webinars please register. You'll get an email after you register with information about how to join the webinar.

  • Instructions for how to join the webinar will be emailed to you after May 29.

  • If you require special accomodations please contact Kay Morrison at 206-553-8321 or within 2 weeks of the presentation.

The Human Health Risk Assessment (PDF) (1,989 pages, 192 MB) is available on EPA’s website. EPA will be accepting feedback on the draft Human Health Risk Assessment through July 24. Comments can be submitted:

EPA is studying contamination in the Columbia River from the U.S./Canada border to the Grand Coulee Dam and surrounding upland areas. The study is called a Remedial Investigation and Feasibility Study. The RI/FS is the step in the Superfund cleanup process that is conducted to gather information to support the selection of a site remedy that will reduce or eliminate the risks associated with contamination.

Past studies of this part of the river by federal and state agencies have shown increased levels of heavy metals such as arsenic, lead, cadmium, copper, mercury, and zinc, and other contaminants like dioxins and furans.

An important part of the RI/FS is the human health risk assessment. A draft of the human health risk assessment is being released to the public on May 26, and will be available through July 24.

If you have questions about the assessment and cannot attend a webinar please contact Robert Tan at: (206) 553-2580
