General geology and groundwater prospecting at Kampung Rahmat, Kuala Krai, Kelantan

Groundwater is used for domestic purposes by the people in the northern part of Kelantan. Normally, they get the water supply from the shallow aquifer through traditionally hand-dug wells as well as from the surrounding rivers. Therefore, this research is important to determine the existence of groundwater especially in the subsurface using the electrical resistivity method. This research was conducted in Kampung Rahmat, Kuala Krai, Kelantan with the title of general geology and the groundwater prospecting at Kg. Rahmat. The study area covers an area of 25 km². The objectives of this study are to produce the geological map of Kg. Rahmat, to identify the aquifer using resistivity method and to determine the physical characteristics of groundwater. Field observation and mapping reveals three types of lithologies present in the study area. It includes granite, shale and andesite porphyry. The groundwater potential at the study area was done by using electrical resistivity method (ERI). The potential aquifer area at the study area was determined. Result from the research is firstly, the geological map is updated to the latest information on the scale of 1:25000. The groundwater potential area and the physical characteristics of groundwater were determined. The further investigation like drilling purpose should be continues as it benefits the community.
