Environmental Influencing Factors of Permeability on Contaminative Aquifer Medium by Ethanol Blended Gasoline

Different ethanol concentration of gasoline components have a significant influence on the permeability of aquifer medium. Because the different of pollutant concentrations will change the environment of aquifer medium, bring on jamming the pore space of medium and influence the hydraulic conductivity and bioremediation of pollutants in aquifer. This study focuses the environmental influencing factors of permeability on contaminated porous medium via four sand columns experiments. Results show that environmental influencing factors of permeability are dissolved oxygen, temperature, PH value and conductivity, and the dissolved oxygen is the main influencing factor of permeability.
