EXPERIENCE

As the Director of Technology for TRS, Mr. Smith is responsible for leading the research and development of our efforts of combining remediation technologies including heat enhanced biological and abiotic in situ destruction of chlorinated solvents and petroleum hydrocarbons. He will also support the TRS engineering, operations, project management and business development departments.

Mr. Smith has over 25 years of diversified environmental, engineering and geo-hydrologic experience. This experience includes the following application of innovative in situ soil and groundwater remediation technologies:

• Combining the use of in situ steam injection and enhanced biological treatment, resulting in the award of U.S. Patent No. 5,279,740.  This method was successfully applied at 2 locations for the cleanup of perchloroethene, trichloroethene, and 1,1,1-trichloroethane, removing 10s of thousands of pounds of solvents from each site, and achieving no further remediation determinations from Illinois EPA.
• The first full-scale application of in situ electrical resistivity heating beneath the water table.  This application was demonstrated effective, achieving a no further remediation determination from Illinois EPA.  Mr. Smith has been involved with the application of ERH at 8 sites across the United States.
• Worked with Argonne National laboratory to pioneer the use of stable isotopes of chlorine and carbon to diagnose the fate of chlorinated compounds (i.e., evaporation or biodegradation) during in situ thermal remediation.  This analysis was used to determine the appropriate time to discontinue the (expensive) thermal treatment and allow (the less costly) intrinsic biodegradation to take over.
• In situ chemical oxidation, and pH and redox manipulation to modify the zero point of charge (Zpc) on soil minerals to facilitate recovery/treatment.  This method resulted in improved recovery of contaminants, and enhanced the intrinsic biodegradation process, foreshortening the remediation timeframe,
• Redox and geochemical manipulation through the use of magnesium and calcium sulfate to enhance anaerobic in situ biodegradation of aromatic and fuels.  This method was used to enhance the anaerobic biodegradation of fuels, whereby significantly more oxygen can be added as gypsum that can be added in alternate forms.  This method also proved effective in controlling the generation of vinyl chloride and chloroethane in groundwater

As a result of the in situ thermal remediation experience, in 2002, Mr. Smith was asked by the U.S. Army Corp of Engineers and U.S. EPA Technical Innovation Office to lead the effort and co-author an engineering manual for the application of in situ thermal remediation technologies.  This is to be published by U.S. EPA in late 2006.  Further, as result of this experience, Mr. Smith participated in a Blue panel review committee for Oak Ridge National Laboratory to evaluate in situ thermal remediation technologies for the redevelopment of a portion of the reserve for the East Tennessee Technology Park, the site of uranium processing for the Manhattan Project during World War II.

Mr. Smith has also co-authored an encyclopedic dictionary of hydrogeology, scheduled to be published by Academic Press in September 2006.

More recently, Mr. Smith has been involved in establishing third party liability transfers, obtaining bindable quotes, and performing remediation dealing with a wide range of environmental contaminants including arsenic, chromium, fuels, chlorinated industrial solvents, copper sulfate, and black liquor.

Mr. Smith has also been on the design team for a zero valent iron permeable reactive barrier to treat arsenic and perchloroethene in groundwater in Maine.  This would be the first full scale ZVI PRB for treating arsenic in groundwater.
