Abstract Self-potential survey was carried out in Kalamunda area of Perth Western Australia with aim of delineating groundwater contaminant plums leakages. Two self-potential electrode configuration the roving dipole where one electrode is left in a base position while the other electrode scouts each survey position and the leapfrogging approach were potential differences are measured between consecutive sample stations along the line were employed to collect data. Results obtained from the experiments shows numerous small circular potential anomalies which could be interpreted as sources of leakages due to geothermal activity but the only trends that could be correlated across all surveys were the linear E-W trend which shows the location and the direction of the pipe underground to a depth of perhaps 2m. Other anomalies on the map show variations which could be as a result of trees interference on the observed data.
