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 re-seal 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.
