The use of in situ chemical oxidation ISCO for treatment of chlorinated solvent source areas is rapidly increasing as Department of Defense DoD and other stakeholders search for remedial approaches that reduce long-term operations and maintenance requirements. While ISCO is a promising technology for some chemicals, there remains significant data needs related to 1 reaction kinetics for common DoD contaminants 2 the effects of natural oxidant demand on oxidant mobility and delivery under varying site conditions and 3 the effects of ISCO on long-term groundwater quality. This study, Strategic Environmental Research and Development Program SERDP research project CU-1289 An Improved Understanding of In Situ Chemical Oxidation, focused on addressing these data needs for permanganate, persulfate and Fentons reagent. The overall goal of this research program was to address critical research needs for the improved implementation of ISCO using Fentons reagent, persulfate or permanganate. These critical research needs include Technical Objective 1, the development of a comprehensive kinetic perspective on the kinetics of oxidation of common DoD contaminants by the most commonly used oxidants, permanganate MnO4 -, Fentons reagent H2O2Fe2 and persulfate and Technical Objective 2, assess how soil properties e.g., soil mineralogy, natural carbon content affect oxidant mobility and stability in the subsurface, and develop a standardized natural oxidant demand NOD measurement protocol.
