Abstract

This paper focused on the quality of surface and groundwater at the ex-promontory-land of Carey Island in Selangor, Malaysia, to study the effects of salinity and agricultural activities on groundwater aquifers. Groundwater quality was measured regularly by using ion chromatography from November 2010 to April 2012. High amounts of Na+ (6377 mgL-1) and Cl- (10,643 mgL-1) showed that seawater intrusion has occurred. High amount of nutrients such as NH4+ (36.06 mgL-1), PO4- (647.61 mgL- 1), NO2- (13,543 mgL-1) and NO3- (33.82 mgL-1) were also found in the groundwater indicating long term fertilizers application on the land. Other physical parameters such as total dissolved solids, pH, conductivity and water table were also determined to trace out the groundwater quality trends.
