Abstract
A system for determining the location of a leak in a pond liner made of electrically insulating material supported by a medium which is electrically conductive consists of a movable nozzle for directing a stream of an electrically conductive liquid against the liner, a ground electrode connected to the electrically conductive supporting medium exterior of the pond and liner, a current source connected between the nozzle and the ground electrode, and a galvanometer located in the electrical circuit comprising the nozzle, current source and ground electrode for monitoring at least one electrical property in the circuit when a change in an electrical property occurs as a result of the stream of electrically conductive liquid completing the circuit by contacting the supporting medium through a hole in the liner.
