DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Killeen, Texas
We travel to your Fort Cavazos contractor facility, fleet yard, manufacturing plant, or job site and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Killeen is the primary civilian community adjacent to Fort Cavazos (formerly Fort Hood) — the largest active-duty military installation in the United States by land area, covering over 214,000 acres in Bell and Coryell Counties and home to the Army's III Armored Corps. The defense contractor ecosystem around Fort Cavazos — including logistics support, vehicle maintenance, construction, IT services, and facilities management contractors — represents one of the densest concentrations of federal contractor Non-DOT drug testing demand in the country. Defense contractors operating at Fort Cavazos include DynCorp International, Vectrus (now Amentum), PAE Government Services, and dozens of smaller prime and sub-contractors. BNSF Railway operates through Bell County on its main line. Killeen-Fort Hood Regional Airport (GRK) serves the installation with commercial air service and military aviation operations. McLane Company, headquartered in Temple adjacent to Killeen, operates distribution fleet logistics that require FMCSA testing compliance. For contractors whose entire workforce operates in and around a military installation, mobile testing at the contractor facility — not a clinic in Killeen — is the only practical model.
OnSite Employer Testing coordinates mobile drug testing collections at your Killeen contractor facility, fleet yard, or job site. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Killeen Employers Need Mobile Testing
Fort Cavazos generates continuous contractor workforce cycling. Defense contractors supporting the installation bring in new employees on a rolling basis tied to contract award cycles, deployment support operations, and vehicle fleet surges. Pre-employment testing for a new contractor employee who reports to work Monday morning cannot wait for a Tuesday clinic opening. Mobile collection at the contractor's Killeen office or staging area keeps the hiring pipeline running without the delays that clinic-based testing imposes.
The sheer workforce volume around Fort Cavazos — the installation's total employment exceeds 45,000 military personnel with a proportional civilian and contractor population — means that any local clinic servicing the Fort Cavazos contractor community is operating at capacity during contractor mobilization surges. Mobile testing at the contractor's facility, not a clinic queue, is the model that scales with contractor demand.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Killeen
Fort Cavazos Defense Contractors
Defense contractors providing logistics, vehicle maintenance, facilities management, construction, and IT support at Fort Cavazos are subject to Drug-Free Workplace Act requirements and typically maintain Non-DOT company-policy programs as a condition of their federal contracts. Amentum (formerly Vectrus and PAE), DynCorp, Leidos, and other major defense service contractors operating at the installation require pre-employment, random, and post-accident testing programs for their contract workforces. CDL-operating contractors on the installation additionally require FMCSA 49 CFR Part 382 programs. We coordinate both DOT drug testing and Non-DOT workplace drug testing for Fort Cavazos contractors at their Killeen-area facilities.
Construction — Fort Cavazos and Bell County
Active military construction (MILCON) projects and Bell County commercial and infrastructure construction generate significant construction contractor testing demand around Killeen. General contractors and specialty subcontractors working on MILCON projects at Fort Cavazos maintain Non-DOT programs under their federal contract drug-free workplace requirements. CDL crane and heavy equipment operators require FMCSA programs. We coordinate both program types at contractor yards and job site trailers throughout Bell County.
Rail — BNSF Bell County Operations
BNSF Railway operates through Bell County on its main line between Fort Worth and San Antonio. FRA 49 CFR Part 219 requires covered BNSF employees in the Bell County area to participate in random, post-accident, and reasonable suspicion programs. We coordinate FRA-compliant DOT drug testing collections at BNSF facilities and crew reporting points in Bell County.
Logistics and Distribution — Temple Corridor
McLane Company, headquartered in Temple and operating distribution facilities serving the Central Texas corridor, runs FMCSA-regulated CDL driver fleets delivering to convenience, grocery, and restaurant customers throughout Texas. The Killeen–Temple distribution corridor generates ongoing CDL pre-employment and random testing demand. We coordinate logistics and transportation collections at carrier facilities and distribution dock areas in Bell and Coryell Counties.
Aviation — Killeen-Fort Hood Regional Airport
Killeen-Fort Hood Regional Airport (GRK) serves American Airlines flights and supports military charter and contract aviation operations tied to Fort Cavazos.

Questions from employers in this region
Amentum has a contract at Fort Cavazos that requires pre-employment testing before new employees begin on-installation work. Can you coordinate testing at Amentum's Killeen office before the employee goes on-post?
Yes. Pre-employment collections at contractor offices in Killeen — before employees begin on-installation work — are a standard use case. We travel to your office or staging location, complete the collection, and the employee can begin work once a verified negative result is received from the MRO.
Our company has a MILCON contract at Fort Cavazos. The installation requires all construction workers to have a valid drug test within the past 90 days before receiving a base pass. Is that a DOT requirement?
No. A 90-day recency requirement for base access is an installation security requirement — it is a Non-DOT host employer access control standard, not a DOT modal agency regulatory requirement. It is separate from and in addition to any FMCSA DOT program your CDL-operating employees require. Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
We operate a CDL vehicle fleet supporting Fort Cavazos logistics operations. Does operating on a military installation change the FMCSA testing requirements?
Operating on private property — including a military installation — does not exempt CDL drivers from FMCSA 49 CFR Part 382 if they also operate on public roads. If your drivers enter or exit the installation via public roads while operating a CMV that meets the FMCSA definition, FMCSA testing requirements apply. Program design and compliance obligations remain your responsibility — we coordinate the collections.
Can you serve defense contractors in Copperas Cove and Harker Heights as well as Killeen?
Yes. Copperas Cove and Harker Heights are within our standard Bell County service range. Contractors with facilities across the Fort Cavazos corridor can be served at each location.
