ABSTRACT:
A system for monitoring the continuity and potential rate of leakage of an underground tank hole liner formed of a sheet of electrically insulating polymeric material in which a standard current measurement is made of a circuit comprising a standard electrode in the form of a container of electrically insulating material having a small hole in a side thereof and containing an electrically conductive fluid connected to an injection electrode through a current source, the electrodes being immersed in a conductive fluid in the bottom of the tank hole to provide a calibrated liner leakage value, and such measurement is compared with the current provided by a circuit comprising the injection electrode connected to a ground electrode through the current source. If the latter current measurement is less than the standard, the area of the liner tested is considered to meet specifications as regards leakage since the total area of leaks, if any, is no greater than the area of the hole in the standard electrode, where as if the current exceeds the standard value, the liner is deemed not to meet specifications.
