Abstract
The use of a suitable leak-detection system for the prevention and mitigation of pollution due to lining system failures is integral to the proper management of landfill facilities. This paper briefly summarises various methods of leak detection that are currently being practised. The details of a newly developed leak-detection technique are also presented. The tests were conducted to evaluate the performance of the new technique by use of controlled leakage. The resulting resistivity profiles for Perth soil in Australia were obtained at 10 min. This method is found to be effective in detecting and locating liner leakage issues within 30 min from the instant when the defect develops. The electrical resistivity decreases with an increase in the leakage duration. The resistivity was found to increase with an increase in the distance/depth from the leak point. Installation of this innovative detection system below liners can enable the various waste containment facilities, such as landfills and leachate ponds, to monitor the lining systems and in case of failures, to take timely action for hazard mitigation. Results presented in this study can be useful for further development of sensors for leakage detection in lining systems
