FIELD TEST OF ELECTROKINETICALLY-DELIVERED THERMALLY ACTIVATED PERSULFATE FOR REMEDIATION OF CHLORINATED SOLVENTS IN CLAY
Head, N.A., Master's thesis, University of Western Ontario, 160 pp, 2018
This field-scale study investigated the novel approach of applying electrokinetics (EK) to enhance the delivery of persulfate and electrical resistance heating (ERH) to activate the delivered persulfate for low-permeability soil remediation. Results demonstrated that EK has the potential to enhance delivery, where the overall mass of persulfate that was observed to be delivered into the chlorinated solvent-impacted clay formation of the field site being a factor of both EK and advection. The application of ERH to activate the delivered persulfate was found to be precluded by catalytic reactions involving naturally occurring iron. Significant chlorinated solvent reduction was observed in groundwater (>80%) resulting from chemical oxidation and dilution from advective flux. https://ir.lib.uwo.ca/cgi/viewcontent.cgi?article=7732&context=etd
