Greenville, SC Mobile Drug & Alcohol Testing
BMW · Michelin · GE Power · GSP Airport FAA · I-85 FMCSA — Mobile collections at the engine of Upstate South Carolina's manufacturing boom.
Greenville anchors Upstate South Carolina's extraordinary advanced manufacturing corridor — one of the most productive in the United States. BMW's Spartanburg plant (the largest BMW plant in the world by volume) is 30 minutes away; Michelin's North American headquarters is in Greenville; GE Power and Fluor Corporation anchor an enormous energy and industrial services base. The I-85 corridor between Atlanta and Charlotte runs directly through Greenville, making it one of the Southeast's most active CDL freight routes. Greenville-Spartanburg International Airport (GSP) serves growing commercial and cargo aviation. OnSite Employer Testing covers all of Greenville County and the Upstate corridor.
OnSite Employer Testing coordinates mobile drug testing collections at your Greenville-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.
