History
Formed as a Wyoming corporation in January 1999, AristaTek is a certified HUBZone small business concern located in Laramie, WY. The four founders are former employees of the University of Wyoming Research Corporation (UWRC) and were the core technical staff of the Hazardous Materials Research Group that conducted field scale research studies at the Nevada Test Site’s Hazmat Spill Center (HSC). The research was mandated in the 80’s when Congress decided to include UWRC in the 1986 Superfund and Reauthorization Act (SARA) to investigate and develop new hazardous chemical technology while developing a Technology Transfer Program to convey these new technologies to the public sector. Again in 1990, UWRC was directed in the Clean Air Act Amendments (CAAA) to develop calibrated data sets of field-scale vapor cloud dispersion releases of dense-gas stimulants under worst-case scenarios that would be used to establish a basis for the Risk Management Plans (RMPs) to be implemented in 1999. These investigations were funded by industry, DOE and EPA and managed by the UWRC technical staff that eventually formed the AristaTek spin-off.

The field-scale research studies involved source strength studies to validate mathematical model formulations for the evaporation rates of liquid chlorine and liquid anhydrous ammonia in the existing wind tunnel at the HSC. The vapor dispersion studies culminated in the Kit Fox Series conducted in the summer of 1995 that were the first of a kind investigations to document dispersion of heavier-than-air gases under neutral and stable meteorological conditions across multiple surface roughness configurations. The project required management and collaboration with ten petrochemical participants*, DOE’s Office of Fossil Energy, DOE’s Office of Nonproliferation and National Security, EPA’s Office of Research and Development, EPA’s Chemical Emergency Preparedness and Prevention Office, University of Nevada – Reno, and US Army’s Dugway Proving Grounds.
