Abstract
The concrete or soil protection layer, placed on geomembrane, laid over slope surface of the landfills, makes electric circuit to connect inside and outside of stock yard. In this condition, it is too difficult to search and locate the leak points of geomembrane liner by the electrical leak detection systems due to electric potential and current anomaly can't occur close by the leakage point.
Authors have developed the new electrical leakage detection method for the landfill which search leakage by current measuring under controlled electric potential field. This paper presents some principles of our electrical leakage detection system audits ability, examined by an experiment.
