A variety of toxic organics, including dense nonaqueous-phase liquid (DNAPL), are amenable to destruction or at least partial degradation through chemical oxidation processes initiated by the application of compounds such as potassium permanganate or Fenton's reagent. The most recent advances in the understanding of the application of in situ chemical oxidation (ISCO) for ground-water remediation are presented through this multimedia training tool.

Principles and Practices of In Situ Chemical Oxidation: ISCO Short Course
Environmental Security Technology Certification Program (ESTCP), video/documentation, 2010

This video of a short course presented in December 2010 at the SERDP and ESTCP Symposium highlights a technology practices manual developed to enhance site-specific engineering and ensure more predictable, cost-effective performance of ISCO for remediation of contaminated groundwater. Individual modules of the course are available on line, and the material in its entirety is available in a PDF file.

Spreadsheet-Based Modeling of ISCO with Permanganate
Cha, K.Y., T. Simpkin, and R.C. Borden. Remediation Journal, Vol 22 No 1, p 43-58, 2011

CDISCO, a Microsoft Excel spreadsheet-based model, can be used to assist with the design of in situ chemical oxidation (ISCO) systems that use permanganate (MnO4-). The model inputs are the aquifer characteristics (porosity, hydraulic conductivity, effective aquifer thickness, natural oxidant demand, kinetic parameters, contaminant concentrations), injection conditions (permanganate injection concentration, flow rate, duration), and unit costs for reagent, drilling, and labor. Permanganate transport in the aquifer is simulated and used to estimate the effective radius of influence (ROI) and required injection-point spacing. CDISCO then provides a preliminary cost estimate for the selected design conditions. The user can perform multiple runs of CDISCO to optimize the cost of the ISCO design. Comparisons with analytical and numerical models of nonreactive and reactive transport demonstrate that CDISCO accurately simulates permanganate transport and consumption. Comparison of CDISCO results with 3-D heterogeneous simulations show that aquifer volume contact efficiency and contaminant mass treatment efficiency are closely correlated with the ROI overlap factor.
