Objective:

The overall objective of the project was to investigate the use of biochemical reductive processes for remediation of contaminated soils. The specific goal was the development and pilot demonstration of the in-situ remediation of trinitrotoluene (TNT)-contaminated soil using an initial reduction of TNT with natural organic matter as catalysts under controlled conditions followed by enhanced mineralization under oxidizing conditions.

Approach:

Each of the participating institutions had a specific set of objectives on which they worked but overall all pilot-scale demonstration projects and associated research was performed at Georgia Tech, all degradation pathway studies were done at Rice while LSU performed the analytical studies on transport behavior via static and dynamic components.
