Geology and delineation of groundwater potential zone using electrical resistivity method in Kampung Pulau Layak

The present study conducted in Kampung Pulau Layak, Dabong. This research focused on produce geological map of the study area on 1:25,000 scale and to delineate the existence of groundwater potential zone. The community in this area is depends on the surface water and in future, there may be water shortage. Geological mapping conducted through many fieldwork and sampling. The lithologies were updated in geological map which shows the distribution of phyllite, schist and shale. For electrical resistivity, there are three locations selected for electrical resistivity survey. The first location used poledipole electrode configuration while the other two lines use Schlumberger electrode configuration. The resistivity data of three lines were collected by using ABEM Terrameter LS1 and later analysed by using RES2DINV software. The results showed that there is fractured zone in survey line 1 and survey line 2 showed a layer assumed as fracture aquifer while line 3, water in weathered zone. The method shows reliability for identifying groundwater potential zone in the study area. The findings of this research will be useful in future for practitioners for references.
