Biofouling effects on in situ TCE bioremediation by phenol utilizers
- Stanford Univ., CA (United States). Civil Engineering Dept.
In situ bioremediation involves stimulating the growth of bacteria within the contaminated region of an aquifer to break down the contaminants. This large bacteria population often can have the unwanted effect of clogging the porous media. The clogging reduces the porosity and the hydraulic conductivity of the soil. These hydrodynamic changes can affect the flow of groundwater used to deliver nutrients to the bacteria in the contaminated region of the aquifer. The authors developed a mathematical model to study the impact of biofouling on a recirculation well flow system used to mix nutrients with contaminated groundwater. The insights gained from this examination can aid in designing a system to minimize biofouling problems.
