Recent Case Studies


  • Cold Weather Injections at Remote Site

    Project Category: ,

    A historical leaking UST resulted in contamination to soil and groundwater inside a remote National Park. A Risk Assessment identified concerns over benzene concentrations for a planned building expansion. Excavation was ruled out due to the depth of the impacts (up to 8 mbgs) and disruption to the environmentally-sensitive area. As such, ISCO was selected

  • PHC High Resolution Site Characterization Survey

    Project Category: ,

    A historic leak from a UST released over 19,000 L of gasoline directly into the subsurface over a five year period. Extensive borehole drilling and monitoring well installations were completed. A downgradient area of high PHC concentrations was discovered extending up to 26 meters below ground surface. Traditionally, this would serve as delineation of impacted
