When a direct-current (dc) electric field is applied to a dilute clay suspension, negatively charged clay particles are moved toward the anode (Positive electrode). This electrokinetic phenomenon is used to reseal leaking geomembrane liners while they are in service. The basis of this innovative environmental protection technology and the results obtained from full-scale evaluation of the feasibility of the technology are presented in the paper. The significant reduction in leakage rate from a geomembrane lined surface impoundment caused by the formation clay cake at the leak indicates the technology is feasible.
