A leak in a geomembrane lined impoundment or landfill has a characteristic electrical response. The author simulated the waste material, the liner, and the soil under the liner by infinite horizontal layers and express the secondary potential for a leak in the geomembrane liner in terms of a three-layer medium Green's function and in the unknown current density distribution at the leak. The area of the leak is sufficiently small for the leak current density to be essentially uniform. The author added the primary potential associated with a leak-free liner to the secondary potential to form an integral equation and derive a general expression for the current density at the boundary between the waste material and the liner. From the expression for the current density, The author determined the current flow through the leak and the amplitude of the leak anomaly response. Multiple circular leaks in the thin resistive liner are included in the analysis.
