Presentation Description
Principles and Practices of In Situ Chemical Oxidation for Remediation of Contaminated Sites
In situ chemical oxidation (ISCO) has emerged as one of several viable methods for remediation of organically contaminated sites.  Effective application of ISCO at a particular site depends on a clear and thorough understanding of ISCO and its applicability to a given set of contaminant and site conditions to achieve site-specific treatment goals.  During this presentation, the principles and practices of ISCO will be explored based on a review of the scientific literature, an analysis of over 200 field applications, and the results of a technology practices workshop.  The presentation will also highlight an ongoing ESTCP project that is developing guidance and decision-support tools within a technology practices manual that is designed to enhance the site-specific engineering of ISCO for remediation of contaminated groundwater.
