Abstract

A study of groundwater potential of Ganduman Formation in Dent Peninsular, Sabah was carried out using Vertical Electrical Sounding (VES) method. A total of 25 VES stations were carried out across the Ganduman Formation area using SAS300C Terrameter with schlumberger electrode array configuration. The sounding data were processed and interpreted using the curve matching technique and PROGRESS interpretation software. The Ganduman Formation comprises variable thickness sandstone interbedded with thin mudstone or clay layers. The VES results revealed that the substratum of Ganduman Formations generally characterized by four to five geoelectrical layers. The VES interpretation results were used to generate five profiles of resistivity sections (G1, G2, G3 G4 & G5) from which the potential aquifer layers are identified. In conjunction with borehole data, the results show that low resistivity sandy layer constituted the aquiferous zone in all the VES stations. Profile G1, G2 and G4 appear to have thick sandstone layers which indicate there are better aquifers potential compared to profile G3 and G5.
