Facebook Preview Thumbnail

The Lake Roosevelt Forum recently published the Public Guide of the 2020 Draft Human Health Risk Assessment for the Lake Roosevelt and Upper Columbia River Remedial Investigation and Feasibility Study (UCR RI/FS).

The 2020 Public Guide provides data on the EPA’s draft Human Health Risk Assessment (HHRA). The HHRA investigates the heavy metal toxins of concern, the multiple exposure pathways, and the exposed population. The EPA uses established benchmarks to access the risk to residents and visitors, and implement risk prevention.

The Public Guide also provides details on samplings, cleanups, and other actions conducted by Teck, and overseen by the EPA, during the Lake Roosevelt and Upper Columbia River Remedial Investigation. The results of which were used in the HHRA. The Guide also provides the public with precautionary measures to protect visitors and residents who may be exposed to contaminants of concern.

Human Health Risk Assessment Webinar

Dear CCC members and friends,

We have the opportunity, as one of the communities most affected by Teck smelter discharges into the air and water, to provide comments on the EPA’s Human Health Risk Assessment. This document estimates the nature and probability of adverse health effects in humans who may be exposed to chemicals in contaminated environmental media, now or in the future. It will be used to help determine the need for cleanup or other remedial measures to reduce contaminant exposure and protect public health.

As you read through this document, you might consider the effectiveness of past removal actions and whether they were sufficient, whether there are any exposure media (e.g., water, beaches) that have not been fully considered, if you are comfortable with the conclusions about the safety of beaches and fish consumption, and which lead benchmarks should be used for clean-up.

To help prepare you for making comments, the Environmental Protection Agency (EPA) will be holding two identical webinars, on June 10 and July 15, both starting at 5:30 pm to give as many people as possible a chance to learn more about the HHRA directly from the EPA. If you wish to attend the webinars, please preregister at:

The draft Human Health Risk Assessment is available on EPA’s website:

Comments must be received by July 24th. If you have questions about the assessment and cannot attend a webinar please contact Robert Tan at: (206) 553-2580. Also, feel free to email me if needed; best address is smithm69@msu.edu.

Best to all and stay safe and well,
