CAPLUS Abstract According to the US EPA, 80% of hazardous waste sites in the US have contaminated groundwater. The most common contaminants are chlorinated organic solvents including TCE and tetrachloroethylene (PCE). Because conventional pump and treat methods have limited success in remediating sites where dense non-aqueous phase liquids (DNAPLs) are present, in-situ oxidation using K or Na permanganate is emerging as one of the most effective technologies for DNAPL treatment. The merits of any type of treatment technol. can be assessed in terms of effectiveness, ease of use, reaction rate, and cost. The use of permanganate for in-situ chemical oxidation results in the complete mineralization of TCE and PCE. It is easily handled, mixed and injected as well as inexpensive to design and implement as compared to other technologies. This paper describes recent laboratory evaluations using permanganate for the removal of TCE and PCE. A parametric model that relates all of the factors that can effect the oxidation rate; such as, pH, DIC, TOC, background demand, temperature and the like, describes effectiveness of the permanganate oxidation of TCE and PCE. This paper studied the beginning of the response model based on contaminant concentration and permanganate concentration.
