NOVELTY - Removal of contaminants from soil and ground water, comprises preparing an aqueous emulsion of a sparingly soluble microbe digestible fat or oil; heating the emulsion to pasteurization temperatures and homogenizing the emulsion until a stable emulsion having a particle size below 1 micron is obtained; and injecting substrate under anaerobic conditions into contaminated soil and ground water.    USE - The method is used for removing contaminants, e.g. chlorinated hydrocarbons (claimed), trichloroethene (TCE), trichloroethane (TCA) and their degradation products dichloroethene (DCE) and vinyl chloride (VC), from soil and ground water. It may be used for the bioremediation of halogenated organic compounds, inorganic compounds that can be biodegraded through anaerobic processes and soluble compounds that can be precipitated and immobilized under anaerobic conditions. It can also be used in the denitrification of nitrate to nitrogen gas.    ADVANTAGE - The method provides for long term anaerobic remediation of contaminated soil and ground water. The aqueous emulsion of a sparingly soluble fat or oil effective for remediation has minimal increase in viscosity over water and causes minimal pore blockage in soil. It has superior stability and droplet size for long term remediation of contaminated soil and ground water. The method employs more than one anaerobic electron donor and nutrient. It reduces contaminant levels to below recognized safety levels.    DETAILED DESCRIPTION - Removal of contaminants from soil and ground water using biostimulation to produce an anaerobic treatment zone that enhances biotransformation or immobilization of the target contaminants, comprises preparing an aqueous emulsion of a sparingly soluble microbe digestible fat or oil; heating the emulsion to pasteurization temperatures and homogenizing the emulsion until a stable emulsion having a particle size below 1 micron is obtained; and injecting substrate under anaerobic conditions into contaminated soil and ground water.    DESCRIPTION OF DRAWING(S) - The figure is a side elevation schematic drawing illustrating the remediation process.
