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.
