Description of the Web Site

The U.S. Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) is interested in providing federal and state project managers and other users with timely information about the developments in the field of in situ chemical oxidation technologies. This Web site contains information about completed and on-going full-scale in situ chemical oxidation technology applications. As of August 2008, the Web site included information on 81 in situ chemical oxidation projects. This Web site 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.

The in situ chemical oxidation technologies described in the project profiles on this Web site include the use of chemicals such as:

• Fenton's Reagent
• Ozone
• Permanganate
• Hydrogen Peroxide
• Persulfate

The project profiles contain a summary of available information, including:

• Site Information
  • Project name
  • Site name, location, and type
• Design and Operation Factors
  • Oxidant type, quantity and concentration
  • Project start and end dates
  • Summary and description of performance data
  • Summary and description of costs
• Project Data Elements
  • Project scale and status
  • Contaminants of concern
  • Area of contamination
  • Presence of naturally occurring carbon
  • Geologic setting
  • Geology and hydrogeology
  • Media type
  • Additional performance data
• Additional Information
  • Associated vendors or consultants
  • Points of contact
  • References

The project profiles on in situ chemical oxidation provide varying levels of detail, depending on the data and information available.

Data Sources

EPA obtained data from technical journals, conference proceedings, and information provided by various technology vendors and site managers to prepare the profiles.

How to Search the Web Site

The Web site provides a search engine that allows a user to search the profiles by site name, state, type, contaminant, media contaminated, geologic setting, oxidant type, project status, or project scale. A user may also select the button “List All,” which presents a list of all available profiles. Search results are sorted alphabetically by project name.

How to Provide Updates about an In Situ Chemical Oxidation Project Profile or to Submit a New Profile

To provide information about a new or updated in situ chemical oxidation project, please download the project submittal form, enter all relevant details about the project, and e-mail the form, along with any supporting documents, to Jim Cummings at cummings.james@epa.gov.

To provide updates about a project profile, please contact Jim Cummings of EPA’s OSRTI at cummings.james@epa.gov, or by telephone at (703) 603-7197, with the updated information you would like to include.

Additional Resources

EPA resources that contain general information about in situ chemical oxidation projects are available in the In Situ Oxidation section of CLU-IN's Technology Focus.

Future Plans for the Web Site

EPA is preparing more profiles and links for more information on in situ chemical oxidation projects as information becomes available.
