DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Watford City, ND Mobile Drug & Alcohol Testing
McKenzie County Bakken crude oil tanker fleets · PHMSA pipeline and gathering system operators · Man-camp and well site employer workforce · Oilfield services and construction contractors · Same-day dispatch available
McKenzie County consistently ranks as the highest oil-producing county in the United States, and Watford City is its county seat and commercial hub. This is ground zero for the Bakken oil patch - where crude oil tanker trucks run US-85 and US-23 around the clock hauling production from thousands of active well sites, where pipeline gathering networks operated by companies like Crestwood Midstream and Targa Resources require PHMSA-compliant testing for covered employees, and where man-camp operators house thousands of workers in temporary accommodations far from any fixed clinic. The distances involved in McKenzie County make mobile drug testing the only practical compliance option - the nearest clinic to many active well sites can be 50 to 90 minutes away, making a post-accident timing window genuinely difficult to meet without on-site dispatch. Every major oil company active in the Bakken - Continental Resources, Hess, ConocoPhillips, Chord Energy - requires its contractor workforces to maintain drug-free workplace programs as a condition of well site access. OnSite Employer Testing dispatches mobile collectors to Watford City staging areas, pipeline facilities, man-camps, and employer sites throughout McKenzie County when routing and collector availability allow - we confirm feasibility before you hold the schedule.
OnSite Employer Testing coordinates mobile drug testing collections at your Watford City-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.
Watford City sits in the geographic heart of the Bakken oil formation in McKenzie County - the single highest oil-producing county in the United States - where on-site mobile drug testing is not optional, it is the only viable compliance solution.

Applicable Regulations - Watford City, ND
Watford City and McKenzie County carry the densest DOT and PHMSA regulatory exposure of any small jurisdiction in the country. PHMSA-regulated pipeline operators follow 49 CFR Part 199 for covered employees on regulated crude oil and natural gas pipeline systems. CDL crude oil tanker drivers on US-85 and county roads follow 49 CFR Part 382 (FMCSA) and 49 CFR Part 40. HAZMAT endorsement holders transporting flammable crude oil are subject to enhanced random pool inclusion. Non-DOT oilfield service and man-camp employees are governed by company policy and operator contractor qualification programs - major Bakken operators require pre-qualification drug testing and ongoing random programs as a standard condition of well site access. North Dakota's medical marijuana program does not override DOT or PHMSA testing requirements. North Dakota has no recreational cannabis law. Program design remains the employer's responsibility.

Questions from employers in this region
We operate a crude oil gathering pipeline in McKenzie County - what does PHMSA testing require for our employees?
PHMSA 49 CFR Part 199 requires drug and alcohol testing for covered employees performing operations, maintenance, or emergency response on regulated pipeline facilities. This includes pre-employment, random (minimum 25% for drugs and 10% for alcohol per year), post-accident, reasonable cause, return-to-duty, and follow-up testing. PHMSA program requirements differ from FMCSA in rate calculations, covered employee definitions, and some collection procedures. We perform on-site collections for PHMSA-covered programs at your McKenzie County pipeline facilities. Program design and covered employee determinations remain your responsibility.
We run a man-camp operation housing oil patch workers in Watford City - are we required to test our residents or just our own staff?
Your testing obligations depend on who your employer is versus who is simply residing in your facility. Your own employees performing safety-sensitive functions are subject to your company drug-free workplace policy. Residents who work for other companies are that company's testing responsibility. Some man-camp operators also maintain facility access standards requiring residents to be in active drug testing programs as a condition of occupancy. We perform on-site collections at your Watford City facility for your own employee program.
We are a Bakken contractor required by Continental Resources to maintain a drug-free workplace program - can you document our program for operator pre-qualification?
We perform the collection side of your program - that is, dispatching a qualified collector to your site to collect specimens using proper chain-of-custody procedures. The program documentation, MRO selection, policy language, and operator pre-qualification submission are your responsibility. We can provide collection records and documentation consistent with standard DOT or non-DOT custody-and-control requirements for your program records.
