• Abstract:
  A primary goal of the research project is to improve the efficiency and effectiveness of chemical oxidation systems during in-situ treatment of non-aqueous phase liquid (NAPL) source zones. Efficiency and effectiveness are defined in Table 1-1; other selection criteria include time required to achieve acceptable levels of treatment, oxidant selectivity, and oxidant delivery methods. Several novel approaches have been taken to reach the goals of the study. The first approach enhances the application of Fenton's reagent in soil slurry systems, resulting in a better understanding of the magnitude of non-specific oxidant losses relative to consumption by the target compounds. The second approach explores minimizing non-specific losses of the oxidant by introducing the oxidant (KMnO4) in an encapsulated form. Finally, solubility enhancers are examined to enhance the aqueous NAPL concentrations. Significant enhancements in NAPL aqueous concentration will result in corresponding enhancements of the observed oxidation rate.
