Chemical Oxidation Site Profiles

The U.S. Environmental Protection Agency (EPA) has developed this website to summarize timely information about completed and ongoing full-scale applications of in situ chemical oxidation technologies. In situ chemical oxidation requires injection of oxidants into the subsurface. The oxidants chemically break down the organic contaminants to inert compounds such as carbon dioxide, chloride, and water. This technology also provides environmental engineers another tool to treat nonaqueous phase liquids (NAPL), which are difficult to treat using conventional technologies. Projects for this website are collected using information from technical journals, conference proceedings, as well as information obtained from technology vendors and site managers. The project profiles contain information about relevant site background, contaminants, and media, technology design and operation, and cost and performance results, as well as points of contact and references. This website can be used as a networking tool (each profile lists a contact) to identify past solutions and lessons learned that would apply to new sites with similar contaminants and climate.
As of August 2011, the website includes information on 135 in situ chemical oxidation technology projects in various stages of development and deployment. The profiles have documented the use of the in situ chemical oxidation technology for various contaminants in groundwater and soil, such as chlorinated solvents, petroleum products, and pesticide compounds. As further information is obtained, EPA plans to update and expand this website with new project profiles on the in situ chemical oxidation technology and updated information about existing project profiles. EPA is continuing its efforts to examine trends in the use of in situ chemical oxidation technology.
