Columbia, SC Mobile Drug & Alcohol Testing
Fort Jackson · McEntire JNGB · CAE Airport FAA · I-20/I-26 FMCSA · SC State Contractors — Mobile collections at South Carolina's capital.
Columbia is South Carolina's state capital and military training hub. Fort Jackson — the U.S. Army's largest and most active Initial Entry Training installation — processes over 50% of all Army basic training soldiers annually, supporting an enormous defense contractor community. McEntire Joint National Guard Base houses the SC Air National Guard. Columbia Metropolitan Airport (CAE) handles commercial and military aviation. I-20 and I-26 intersect at Columbia, creating one of South Carolina's busiest CDL freight nodes. State government contracting and USC-affiliated research add further testing demand. OnSite Employer Testing covers Richland and Lexington counties.
