Coupling in situ chemical oxidation/reduction (isco/iscr) with bioremediation for sustainable site remediation

Abstract

In the field of remediation it has also become more common to combine two complimentary remediation technologies to present the best technical and economic approach to a given site. This article will examine the use of In Situ Chemical Oxidation (ISCO) utilising RemOx® L ISCO Reagent (sodium permanganate) for source area treatment used in combination with biostimulation for enhanced reductive dechlorination utilizing CAP18 ME® Anaerobic Bioremediation Product for polishing of the source area and treatment of the lower concentration downgradient plume at an industrial dry cleaning facility. The site is a closed industrial dry cleaning facility that is surrounded by both commercial and residential areas. Over the course of the facilities operation, the soil and groundwater at the site became contaminated with tetrachloroethylene (PCE) and trichloroethylene (TCE) which are common chlorinated dry cleaning agents.
