Mobile Drug & Alcohol Testing — Peoria, IL
Caterpillar. Komatsu. Liberty Steel. SC2 Services. Central Illinois's manufacturing and logistics core — collections at your facility.
Peoria is the manufacturing capital of central Illinois. Caterpillar Inc. maintains 12,000 local employees in engineering, manufacturing, and logistics. Komatsu is expanding its Peoria operations with a new facility. Liberty Steel & Wire employs 912 workers producing 700,000 tons of steel annually. SC2 Services (packaging, warehousing, industrial logistics, 1,030 employees) and Advanced Technology Services (industrial machinery maintenance, 1,073 employees) round out a manufacturing cluster where heavy equipment operation, CDL driving, and safety-sensitive work are daily realities.
OnSite Employer Testing coordinates mobile and on-site drug and alcohol testing for Peoria-area employers — DOT and Non-DOT programs for Caterpillar and Komatsu contractors, steel manufacturers, logistics companies, and central Illinois carriers. We travel to your facility. See how it works and all locations.
Why Peoria Employers Need a Reliable Mobile Testing Partner
Peoria's workforce is disproportionately concentrated in industries that require drug and alcohol testing by federal mandate or operational necessity. Over 24,500 people are employed in the manufacturing sector — a workforce density 56% higher than the national average. Construction machinery operators, steel workers, logistics personnel, and long-haul drivers based in Peoria all require ongoing testing programs.
Fixed clinics have limited hours and require employees to leave work. For a Caterpillar contractor running a 6 AM day shift or a steel mill crew on nights, the walk-in clinic model fails. Mobile testing solves this by bringing the program to your site, on your schedule.
Industries We Serve in Peoria and Central Illinois
Heavy Equipment Manufacturing (Caterpillar, Komatsu)
Caterpillar maintains 12,000 local employees and an expansive contractor and subcontractor ecosystem. Komatsu is constructing a new Peoria facility. Contractors and skilled trades workers supporting these employers — along with CDL drivers delivering components — require pre-employment and random testing programs.
We coordinate on-site collections for contractor workforces at Caterpillar and Komatsu facilities — arriving during your shift window at your staging area.
Steel Manufacturing (Liberty Steel & Wire)
Liberty Steel employs 912 workers in a high-hazard steel manufacturing environment, producing wire rod, rebar, and industrial wire. Both Non-DOT production worker programs and DOT programs for fleet and delivery drivers are standard in steel operations of this scale.
We coordinate Non-DOT and DOT collections for manufacturing employers on rotating shift schedules.
Logistics and Warehousing (SC2 Services)
SC2 Services operates packaging, warehousing, industrial painting, and logistics operations across six Peoria-area locations: Bartonville, Delavan, East Peoria, Mossville, Pekin, and Peoria. Multi-site employers with 1,000+ workers need a testing partner who can coordinate collections across all locations in a single visit rotation.
We coordinate multi-site testing routes across the Peoria metro — reducing per-test travel costs for employers with multiple facilities.
FMCSA Trucking and Freight Corridor
Peoria sits at the intersection of I-74 and I-474, with Route 29 running north–south along the Illinois River. FMCSA-regulated carriers operating these corridors require full DOT drug and alcohol programs — pre-employment, random, post-accident, and return-to-duty.
Construction
Commercial and civil construction contractors supporting Caterpillar, Komatsu, and central Illinois infrastructure projects require pre-employment and random testing — either DOT (for CDL vehicle operators) or Non-DOT company-policy programs.

Questions from employers in this region
We are a Caterpillar subcontractor with 30 field workers. What program do you recommend?
For field workers accessing Caterpillar facilities, we recommend a Non-DOT pre-employment plus quarterly random program. If any of your workers drive CDL vehicles, those workers also require a DOT program. We audit your workforce and vehicle roster to determine which employees fall under which program, then build one coordinated testing schedule.
Can you test multiple Peoria-area sites in one visit?
Yes. If you operate across Peoria, East Peoria, and Bartonville — as SC2 Services does, for example — we coordinate a single visit route covering all locations in sequence. This is significantly more cost-effective than scheduling separate visits per site.
Do you serve Peoria regularly or only by special request?
We serve Peoria on a scheduled route basis, batching testing visits to serve multiple central Illinois employers on the same trip. For regularly scheduled random programs, we build your facility into our central Illinois rotation. For urgent post-accident or for-cause needs, call (219) 315-0345 immediately.
Our steel mill runs 24/7 with rotating shifts. Can you test across all three shifts?
Yes. We accommodate shift-specific testing windows. For a 24/7 facility, we recommend a random draw that allocates employees proportionally across shifts so no shift bears a disproportionate testing burden. Nights and weekends are available with advance scheduling.
