There is current interest in finding sustainable remediation technologies for the removal of contaminants from soil and groundwater. This review focuses on the combination of electrokinetics, the use of an electric potential to move organic and inorganic compounds, or charged particles/organisms in the subsurface independent of hydraulic conductivity; and(More)
Physical heterogeneity in the subsurface poses significant problems for the bioremediation of contaminants, these include: (1) delivery of biological amendments to stimulate bioremediation by hydraulic techniques is limited to soils and sediments with hydraulic conductivities above around 10-7 m s-1 [1]; and (2) physical heterogeneity imparts controls on(More)
