In Situ Chemical Oxidation (ISCO) has been shown to be a very effective remedial alternative for a broad-range of petroleum, PAH, and chlorinated solvent contaminants. Slug injections can be used to deliver the chemical to the subsurface where spot treatment is desired. ETEC improves upon the typical slug injection of chemical oxidants by incorporating our ISD™ equipment to create a temporary re-circulation cell. This recirculation approach enables us to deliver the appropriate mass of chemical oxidants/catalysts to the subsurface and to achieve a greater degree of contact between the contaminants and oxidants than what would be possible with a typical slug injection.

| Selecting the most appropriate chemical oxidant for a particular contaminant is as critical as selecting the right delivery system. ETEC has utilized many different chemical oxidation processes in combination with ISD™ equipment. Before implementation of most of these methods, ETEC highly recommends conducting bench-scale tests with impacted media from the site. Many factors affect chemical oxidation (ex. type of catalyst, concentrations of oxidant, natural organic material, etc.), and ETEC can conduct thorough bench-scale experiments to evaluate different concentrations of oxidants and metal catalysts that will provide you the most cost-effective approach prior to application at the site.
