Bench-scale and pilot-scale studies demonstrate that ionic contaminant species, some organic contaminants, and certain radionuclides can be removed efficiently from fine-grained deposits by application of electrical currents across a soil mass, through electrodes that allow egress and ingress of a pore fluid. This technique (electrokinetic remediation or electrochemical soil processing) results in soil acidification, contaminant desorption, transport, accumulation, and removal. A review of the fundamentals of the process and the theoretical development, together with a review of considerations and limitations for full-scale application of the technique for site remediation, are presented.
