EXPERTISE

GSI develops innovative site remediation technologies; teams with academic / industry / military partners for technology development; and works with government and industry transferring new technology to potential end users.

REPRESENTATIVE EXPERIENCE

Technology: Developed patented new remediation technology for chlorinated solvent sites involving direct hydrogen delivery with Rice University partner. The technology is now being funded by the U.S. Air Force, the U.S. Dept. of Defense Strategic Environmental Research and Development Program (SERDP), and U.S. EPA's Hazardous Substance Research Center.

Long-Term Monitoring: Developed Air Force's MAROS Long Term Monitoring Decision Support System software with University of Houston to help site owners reduce long term monitoring costs.

Barriers: Developed an in-situ, permeable, mulch filled biowall to treat chlorinated solvent-impacted groundwater. The development of this technology is currently being funded by the Air Force Center for Environmental Excellence.

Radionuclides: Developed and patented innovative Ensorb technology for managing dissolved radionuclides in subsurface.

Natural Attenuation: Developed key natural attenuation models BIOSCREEN and BIOCHLOR and now developing an innovative source lifetime estimation tool for the US Air Force.

Tech Transfer: Wrote numerous tech transfer documents for US EPA, state regulatory agencies, companies, and American Petroleum Institute, including US EPA LNAPL and DNAPL Fact sheets.

Books: Co-authored two groundwater books, Natural Attenuation of Fuels and Chlorinated Solvents, published by John Wiley & Sons; and Ground Water Contamination: Transport and Remediation, published by Prentice Hall.
