DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Yakima, Washington Mobile Drug & Alcohol Testing
Tree Fruit & Hop Agriculture · Food Processing · I-82 FMCSA · Central Washington — Mobile collections in the heart of Washington's orchard country.
Yakima Valley is the most productive agricultural region in Washington State — producing 70%+ of the nation's hops, vast quantities of apples, pears, and cherries, and substantial wine grape production. Cold storage, packing houses, and food processing operations employ thousands of seasonal and permanent workers. CDL fleet activity on I-82 and US-97 is heavily agricultural. The rapid growth of craft brewing and cider production industries adds employer testing demand. OnSite Employer Testing covers all of Yakima County and the broader Central Washington agricultural corridor.
OnSite Employer Testing coordinates mobile drug testing collections at your Yakima-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.
