Riverton sits in Fremont County at the heart of the Wind River Basin, surrounded by active oil and gas production, uranium mining operations, and a Wind River Indian Reservation economy that includes tribal enterprise employers. The Wind River Basin is one of Wyoming's most active natural gas production regions, with pipeline gathering operations and oilfield service companies staging from Riverton to serve surrounding fields. Uranium mining has a historical presence in Fremont County with in-situ recovery operations at sites operated by Uranium One and Peninsula Energy - a unique mining employer type with specific safety and contractor testing requirements. US-26 and US-789 route freight between Riverton and Casper to the east and the Idaho/Utah border to the west. SageWest Health Care anchors healthcare employer demand in Fremont County. OnSite Employer Testing dispatches mobile collectors to Riverton oilfield facilities, mine staging areas, fleet yards, and employer sites throughout Fremont County when routing and collector availability allow.

Questions from employers in this region
We operate a uranium in-situ recovery facility in Fremont County - what drug testing program do we need?
NRC and MSHA do not federally mandate drug testing for uranium in-situ recovery operations. However, NRC licensees typically include drug-free workplace programs in their compliance management systems, and most uranium mine operators maintain programs driven by insurance and corporate safety standards. We dispatch to your Fremont County facility for any employer-designed program when routing allows.
We service natural gas wells in the Wind River Basin staging from Riverton - can you come to our yard for pre-employment and random testing?
Contact us with your yard address and we confirm routing and collector availability for your Fremont County location. Remote Wyoming markets require advance confirmation - we give you a direct answer on feasibility before you hold the schedule.
Wyoming has no cannabis law - how does that affect our Wind River Basin oilfield contractor drug policy?
Wyoming's zero-tolerance environment means no state-law cannabis defense for any employee. For oilfield contractors whose operator clients require drug-free workplace programs as a condition of well site access, Wyoming law creates no friction with those requirements. Your written policy governs completely. Policy decisions are the employer's responsibility.
