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:
