CONDENSATE IMPACTS IN FRACTURED BEDROCK
Waddell, J. and C.D. Sandau. Canadian Reclamation, Vol 20 No 1, p 30-32, 2011

TRIUM Environmental Inc. was selected to investigate contamination in subsurface soil and groundwater on an active well site in Alberta. During this project, TRIUM characterized and delineated shallow soil impacts. Upon completion of the baseline site investigation, a pilot-scale in situ chemical oxidation (ISCO) treatment was conducted to evaluate fracture connectivity and ascertain whether a modified Fenton's reagent would reduce contaminant levels effectively. Pilot results showed that the fracture network was highly connected, and good delivery of the oxidant was achieved. The investigation highlighted that an accurate assessment is key to the success of remedial strategies, and the pilot results demonstrated that ISCO is an appropriate method for this site.
