Abstract : At the start of this project, neat and emulsified vegetable oil had been used at several different sites to simulate anaerobic biodegradation of chlorinated solvents and other contaminants in groundwater. However, little was known about the transport, retention and biodegradation of these materials in the subsurface or the impact of these materials on contaminant fate. This project included a series of laboratory, field and numerical modeling studies aimed at improving our understanding of edible oil transport and fate in the subsurface. This information was then used to develop and demonstrate an effective process for enhancing in situ anaerobic biodegradation of ground water contaminants.
