HULING, S. G. IN-SITU CHEMICAL OXIDATION - DNAPL MASS REDUCTION TECHNOLOGY. Presented at EPA's National Association of Remedial Project Managers Conference, Baltimore, MD, May 21, 2007 - May 25, 3007.
Impact/Purpose:
To inform the public.
Description:
In-situ chemical oxidation (ISCO) is a rapidly developing technology used at hazardous waste sites where oxidants and complimentary reagents are injected into the subsurface to transform organic contaminants into less toxic byproducts. This technology is being used at new sites but also at older sites where other remedial technologies had previously been applied. The presentation will involve basic fundamentals, a summary of the state of the practice, technology selection factors, site requirements, limitations/interferences, design considerations, bench- and pilot-scale study guidelines, delivery methods and issues, aquifer plugging, impact on natural attenuation, and chemical rebound.
