CONDENSATE IMPACTS IN FRACTURED BEDROCKWaddell, 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.
