Hermiston Oregon sits adjacent to the Umatilla Chemical Depot — a former US Army chemical weapons storage facility that stored VX nerve agent, GB nerve agent, and mustard blister agent. The chemical weapons have been incinerated, but the site continues environmental remediation. Hermiston is also downstream from several Columbia River dams and faces flooding risk. The city serves as a regional hub for agricultural processing in the Columbia Basin.
