Landfill liner leak detection system and method.

摘要

A landfill liner leak detection and monitoring system and method for determining the existence of a leak in the landfill liner 12. The system consists of a plurality of pipes 14 in the liner underlayer prior to installation of the liner. Each of the plurality of pipes is perforated with pinholes 15 at regular intervals along its length. A tracer chemical is injected into one end of each pipe and air is evacuated through evacuation probed 24 installed in the overlayer 20. The presence or absence of the tracer in the evacuated sample is indicative of the existence of a leak. The presence of tracer in an evacuated sample will be indicative of the position of the liner leak. <IMAGE>
