Bioremediation of Contaminated Groundwater Environments
Project Title: Integrated modeling and experimental evaluation of hydrodynamic and microbial controls on DNAPL dissolution and detoxification (Eric Seagren, Co-PI)
Funding: National Science Foundation
Description:
Microbial dehalorespiration of aqueous-phase chlorinated ethenes and hydrodynamic conditions can both impact the dissolution of non-aqueous phase liquid chlorinated ethene contamination, and the impacts are dependent on the dominant dehalorespiring population. These phenomena are being studied using a 2-dimensional finite volume mathematical model as well as experimental systems of different scales, including a:
Experimental Systems: Microfluidic Groundwater Model
Intermediate-Scale Groundwater Model
