Edible Oil Barriers for Treatment of Chlorinated Solvent and Perchlorate-Contaminated Groundwater

Abstract

The project goals were to: (1) demonstrate and evaluate use of an edible-oil-in-water emulsion as the substrate for stimulating in situ biodegradation of perchlorate and chlorinated volatile organic compounds (CVOC) in groundwater and (2) develop a protocol for its implementation. The pilot tests evaluated the distribution of the emulsion in the aquifer, the impact of substrate injection on permeability and groundwater flow paths, and the changes in contaminant concentrations and biodegradation indicator parameters. The performance objectives for each demonstration were largely achieved, and the results were used to illustrate the cost-effectiveness of the technology both as a PRB and a source area treatment.
