Description: ETPI project homepage

This research contributes to the goals of DOE's Environmental Technology Partnership Program and specifically addresses the recommendations outlined in the workshop on "Basic Research Needs for Environmentally Responsive Technologies of the Future", subsection " Resources Management, Transportation, Recovery, and Renewables". Its purpose is to provide an improved understanding and predictive capability of the fate and transport of industrial mixed waste plumes in subsurface environments. The research is a multidisciplinary experimental and numerical effort that integrates the behavioral dynamics of chemicals and microbes in subsurface environments, with a novel biophysicochemical model. The ultimate goal of this effort is to provide new insights on coupled hydrological, geochemical, and microbial processes that influence contaminant migration and integrate these experimental findings with an advance software system that maintains the conceptual rigor of field-scale processes. The resulting product will facilitate the exploration of possible solutions for industrial waste management problems and energy sources recovery.
