A demonstration of in situ bioremediation of CCL{sub 4} at the Hanford Site

PDF Version Also Available for Download.

Description

The United States Department of Energy`s VOC-Arid Integrated Demonstration Program (VOC/Arid-ID) is developing an in situ bioremediation technology to meet the need for a cost-effective method to clean ground water contaminated with chlorinated solvents, nitrates, or other organic and inorganic contaminants. Currently, a field demonstration of the technology is being conducted at the Hanford site in southeastern Washington state. The goal of this demonstration is to stimulate native denitrifying microorganisms to destroy carbon tetrachloride and nitrate. Contaminants are destroyed by mixing an electron donor (acetate) and an electron acceptor (nitrate) into the aquifer, using a matrix of recirculation wells. This ... continued below

Description

The United States Department of Energy`s VOC-Arid Integrated Demonstration Program (VOC/Arid-ID) is developing an in situ bioremediation technology to meet the need for a cost-effective method to clean ground water contaminated with chlorinated solvents, nitrates, or other organic and inorganic contaminants. Currently, a field demonstration of the technology is being conducted at the Hanford site in southeastern Washington state. The goal of this demonstration is to stimulate native denitrifying microorganisms to destroy carbon tetrachloride and nitrate. Contaminants are destroyed by mixing an electron donor (acetate) and an electron acceptor (nitrate) into the aquifer, using a matrix of recirculation wells. This work also evaluates the effectiveness.of applying scale-up techniques developed in the petrochemical industry to bioremediation. The scale-up process is based on combining fluid mixing and transport predictions with numerical descriptions for biological transport and reaction kinetics. This paper focuses on the necessity of this design approach to select nutrient feeding strategies that limit biofouling while actively destroying contaminants.
