In situ chemical oxidation or ISCO schemes involve the addition of a chemical oxidant, such as potassium permanganate (KMnO4), which destroys chlorinated solvents like TCE in a straightforward reaction. Although ISCO is now regarded as a developing technology in an industrial sense, beyond active flushing schemes, there have been relatively limited investigations in how ISCO might be better used. Our previous study showed that KMnO4 flushing approaches often would be frustrated by the inability to control the delivery of the treatment fluid due to precipitation of low-permeability reaction by-product like MnO2 and other problems. It was therefore suggested that development of a new ISCO scheme that can provide both destruction efficiencies and plugging control would be required.
