Long Island, NY Mobile Drug & Alcohol Testing
Northrop Grumman Aerospace · LIRR FRA · ISP Airport FAA · I-495 FMCSA · Suffolk/Nassau County — Mobile collections across Long Island.
Long Island is home to one of the most concentrated aerospace and defense manufacturing clusters in the United States — Northrop Grumman's Bethpage campus (where the F-14 and lunar module were built), Grumman's legacy supply chain, Servo Dynamics, and hundreds of defense subcontractors spanning Nassau and Suffolk counties. The Long Island Rail Road (LIRR) — the nation's busiest commuter railroad — runs its entire operation on Long Island under FRA jurisdiction. MacArthur Airport (ISP) handles commercial aviation for the eastern suburbs. The I-495 Long Island Expressway is one of the most congested CDL freight corridors in the Northeast. OnSite Employer Testing dispatches throughout Nassau and Suffolk counties from Hauppauge.
OnSite Employer Testing coordinates mobile drug testing collections at your Long Island-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.
