DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Alamosa, Colorado Mobile Drug & Alcohol Testing
San Luis Valley Agriculture · US-160 FMCSA · Remote Southern Colorado — On-site mobile collections where clinics are scarce.
Alamosa is the hub city of Colorado's San Luis Valley — a vast, high-altitude agricultural basin producing potatoes, quinoa, barley, and hemp. CDL fleets on US-160 and US-285 serve agricultural transport and regional freight with no major testing clinic within 60–90 miles for rural operators. OnSite Employer Testing dispatches to the San Luis Valley — farm operations, agricultural processing plants, and construction sites in Alamosa, Conejos, Rio Grande, and Saguache counties.
OnSite Employer Testing coordinates mobile drug testing collections at your Alamosa-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.
