In Situ Application of Potassium Permanganate Solution for VOCs-Impacted Groundwater Cleanup – The Regulatory Perspective

Abstract: In-situ chemical oxidation has been an attractive option as an expedited restoration of aquifers impacted by chlorinated volatile organic compounds (VOCs). Both pilot tests and full-scale application of potassium permanganate (KMnO4) solution have been demonstrated in the field. Compared to typical pump-and-treat technologies, use of chemical oxidation can be significantly faster and more cost-effective to reach cleanup goal. In this paper, the pros and cons of using KMnO4 solution in in-situ restoration of VOCs-impacted aquifer are discussed from a regulatory perspective
