DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
The Dalles, OR Mobile Drug & Alcohol Testing
Columbia River USCG · BNSF/UP FRA Gorge Corridor · I-84 FMCSA · Aluminum & Agriculture — Mobile collections in the Columbia River Gorge.
The Dalles sits at the heart of the Columbia River Gorge — one of the most heavily industrialized stretches of river in the Pacific Northwest. BNSF and Union Pacific run parallel lines along the Oregon side of the gorge, making The Dalles a significant FRA compliance location. Columbia River barge operations add USCG obligations. The nearby Google data center campus (one of the largest in the world) and historic aluminum smelting operations (Alcoa/Columbia Falls Aluminum) round out the area's industrial profile. Cherry and pear orchards generate agricultural CDL activity. OnSite Employer Testing covers Wasco and Hood River counties.
OnSite Employer Testing coordinates mobile drug testing collections at your The Dalles-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.
