The frequency electromagnetic method was employed to investigate the geoelectrical features and map the extent of contamination at a mining abandoned site with the purpose of detecting the spread of groundwater and soil contamination, locating possible pathways of pollution and detecting the buried underground tanks. Based on an electrical conductivity analysis of the survey area, the authors delineated the geophysical anomaly zones. The results show that the frequency electromagnetic method technique is sensitive to conductive layers, has the capability of measuring small changes in subsurface properties in relation to underground water and is thus quite suitable for high-accuracy environmental monitoring.
