Charlotte Metro South · I-77 FMCSA · Manufacturing · York County Growth — Mobile collections at the South Carolina gateway to Charlotte.
Rock Hill and York County sit directly south of Charlotte, NC on I-77 — one of the most active CDL freight corridors in the Carolinas. Lower land costs and proximity to Charlotte's airport and distribution network have attracted Amazon, LKQ, and major manufacturers to the York County industrial parks. The area is one of South Carolina's fastest-growing communities. OnSite Employer Testing serves York County as part of a seamless Charlotte-Rock Hill metro service corridor.
OnSite Employer Testing coordinates mobile drug testing collections at your Rock Hill-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.
