DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Kennewick, Washington Mobile Drug & Alcohol Testing
Hanford DOE Nuclear Site · Columbia River Barge USCG · PHMSA Pipeline · Tri-Cities I-82/I-182 — Federal-grade mobile collections in the Tri-Cities region.
The Kennewick-Richland-Pasco Tri-Cities metro is dominated by the Hanford Site — the DOE's most complex nuclear cleanup project, employing tens of thousands of contractor workers subject to DOE Order 442.1A drug and alcohol testing requirements. Columbia River barge operations (one of the primary commercial navigation corridors in the Pacific Northwest) require USCG 46 CFR Part 16 compliance. Pipeline infrastructure throughout the Columbia Basin carries PHMSA obligations. Agriculture — wine grapes, hops, apples, and onions — generates significant CDL activity on I-82 and I-182. OnSite Employer Testing is the region's go-to mobile collection provider for all Tri-Cities DOE, USCG, PHMSA, and FMCSA obligations.
OnSite Employer Testing coordinates mobile drug testing collections at your Kennewick-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.

DOE Order 442.1A governs Hanford Site federal contractor employees — one of the largest DOE cleanup workforces in the U.S., subject to comprehensive drug and alcohol testing. USCG 46 CFR Part 16 applies to Columbia River merchant mariners. PHMSA 49 CFR Part 199 governs Columbia Basin pipeline workers. FMCSA 49 CFR Part 382 covers CDL fleets on I-82. Washington I-502 does not affect DOE or DOT testing.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
