Geology mapping in Dabong and groundwater quality analysis of quaternary aquifers in Kota Bharu

The quality analysis of groundwater extraction focuses predominantly on the coastal region of Kota Bharu. The field of research ranges from the lower part of Pengkalan Chepa to the upper part of Bachok. A 25-km box covers the study area. There are villages scattered throughout the study area, indicating that the annual groundwater withdrawal is high. The research aims to create an updated map of Kampung Durian Badak, Dabong by using Google Earth, Aerial Photograph and literature review were widely used by using GIS and to conduct quaternary aquifer quality analysis in the study area. In order to produce a geological map, the geology of the study region in Kampung Durian Badak was determined by geological mapping. The area of study has 4 kinds of lithology, mainly mudstone, followed by sandstone, slate, carbonaceous and mica schists. An updated geological map based on geological data produced by ArcGIS software. The result of water sampling indicates that the water from the aquifers are not suitable for drinking purposes due to high content of chemicals which is been eliminated from the Agricultural sectors.
