This review introduces surfactant enhanced in situ chemical oxidation (S-ISCO) technology and compares it to traditional in situ chemical oxidation. An overview of the three most important components of S-ISCO (surfactant/co-solvent mixtures, the catalyst and/or the oxidant and the free radicals) and major factors affecting the application of S-ISCO for the remediation of contaminated sites are included. The review concludes with a detailed explanation of the recent case studies and field applications of S-ISCO and factors affecting its implementation.
