Abstract
A system of leak detection in an impoundment including a first impoundment layer containing a brine solution, a second impoundment layer positioned beneath the first impoundment layer and having a brine-filled space therebetween, a first electrode positioned in the brine-filled space, an injection electrode positioned in the brine solution on the first impoundment layer, a plurality of sensor elements extending outwardly from the injection electrode for measuring electrical potentials at points distal the injection electrode, and a source of power electrically connected to the first electrode and to the injection electrode for passing a current between the electrodes. A probe assembly is connected to the injection electrode for supporting the injection electrode above the first impoundment layer. The sensor elements are arranged generally coplanar to the injection electrode. Each of the sensor elements are separated by an equal distance from an adjacent sensor element. A processor is interconnected to the sensor elements for determining a vector of current flow from the injection electrode toward a leak in the impoundment layer.
