In situ chemical oxidation using potassium permanganate (KMnO4) is an innovative technology applied in the remediation of dense non-aqueous phase liquids (DNAPL) from contaminated groundwater and soil. Experiments were designed to examine important processes that occur during oxidation of pooled DNAPL treated by KMnO4. All experiments were conducted in a two-dimensional tank that contained a single DNAPL pool of either perchloroethylene (PCE) or trichloroethylene (TCE) in a homogeneous porous media. Visual observations and chemical analysis of reactants and products were completed to establish and quantify important oxidation processes. Experimental results showed the effectiveness of KMnO4 treatment and removal of pooled DNAPL to be dependent upon several factors. Extensive manganese dioxide (MnO2) precipitation occurred around the DNAPL pool that potentially reduced the effectiveness of treatment. Significant production of carbon dioxide (CO2) caused de-saturation of the porous media containing the DNAPL. Subsequent reduction of KMnO4 flow into this area resulted in a reduction in treatment efficiency. Mobilization of DNAPL pools due to CO2 degassing was also observed in all experiments. Movement of CO2 gas carrying DNAPL vapour was identified as an important mass transport mechanism.Dept. of Civil and Environmental Engineering.
