Spirit Energy, Underground Storage Tanks (UST)
Geotechnology conducted environmental sampling at 69 retail gasoline service stations for Spirit Energy. The work was the result of a nationwide owner of convenience stores/service stations purchasing these sites from Spirit Energy. Fifty-nine of the sites were located in Missouri while 10 were in Illinois. Geotechnology previously provided environmental services at some of the sites through our relationships with Site Oil and Shell. Spirit Energy is a joint business venture between the two firms.
Geotechnology’s scope of services involved completing an established number of borings at each site to assess potential soil and groundwater impacts from underground storage tanks. The drilling was accomplished with a direct-push sampling unit. Temporary monitoring wells were constructed in each of the borings to assess groundwater conditions. The wells were also used to assess the groundwater flow direction at each site.
Prior to drilling, Geotechnology developed a site specific Health and Safety Plan for each site, and contacted the appropriate state one-call system to locate utilities in public right-of-ways. We also utilized our geophysics group to clear private utilities prior to drilling. The geophysicists used Ground Penetrating Radar (GPR), Radio Detection (RD 4000) Magnetics and Electromagnetics (EM31) to identify underground utilities.
