Some of the populations living along Terengganu coastline where the study area was conducted were still dependent on groundwater as water resource. Therefore, this study is carried out to evaluate the groundwater quality and to identify the source of groundwater quality variation spatially and temporally. It is also carried out to investigate the extent of saltwater intrusion into the coastal aquifer. Groundwater quality monitoring was conducted at 13 sampling wells during dry and wet seasons. Water quality data was evaluated in accordance to National Water Quality Standard (NWQS) for Malaysia and was analysed by using Principal Component Analysis (PCA) to determine the source of water quality variation. Resistivity survey was performed at four different sites to delineate the saltwater intrusion. The 2D resistivity profiles that display the resistivity of subsurface material was produced by applying least-square inversion technique using RES2DINV software. Groundwater quality showed no differences between low and high tide but, it worsen during dry season compared to wet season. This is due to the sea level fluctuation that affects groundwater level and leads to dynamic variation in coastal groundwater quality. During low tide, three major sources that caused groundwater quality deterioration were saltwater contamination (45.55 %), physical pollutant (17.38 %) and biotic component living in water (15.77 %). Station B1, B3 and KT1 were highly affected by saltwater contamination, meanwhile station M3 was highly affected by physical pollutant. Moreover during high tide, four major sources of pollution were saltwater contamination (39.62 %), anthropogenic pollutant (15.97 %), biotic component (13.44 %) and sea level movement (8.67 %). Saltwater contamination was the greatest at station B1, B3 and KT1, meanwhile anthropogenic pollution was the greatest at station M2, M3 and S1. For dry season, groundwater quality was influenced by saltwater contamination (69.90 %) and anthropogenic pollutant (16.66 %). Saltwater contamination was the highest at station B1, B3 and KT1, meanwhile anthropogenic pollutant was the highest at station S1 and M2. During wet season, groundwater quality was influenced by saltwater contamination (49.87 %), anthropogenic pollutant (20.97 %) and dissolution of rock minerals (10.65 %). Groundwater at station B3 was highly influenced by saltwater contamination, meanwhile groundwater at station S1, B1 and KT2 were highly influenced by anthropogenic pollutant. Hierarchical Agglomerative Cluster Analysis (HACA) and 2D model section produced from resistivity survey show that, the extent of saltwater intrusion was the greatest at Besut coastal areas, the second worst was at Kuala Terengganu coastal area and the third was at Marang coastal area and the least was at Kemaman coastal area. Groundwater quality of Terengganu coastal areas are greatly influenced by saltwater due to saltwater intrusion in response to sea level fluctuation. This situation is expected to persist or may even worsen with the increase of global temperature.
