A study was conducted to determine the characteristics and potential use of surface water and groundwater at UTHM campus. Electrical Resistivity Imaging (ERI) was carried out previously in this study to interpret the potential shallow groundwater as to identify the depth and variation of aquifer layer. Three representative groundwater were collected from three new installation boreholes, while surface water was collected from nearest (lakes, swale and retention pond). Nine samples from surface water and groundwater were use and degree correspondences of major cation and major anions among them were analyses in determining their hydrochemical characteristics and the quality suitability for irrigation supply purposes. In general, trend of concentration distribution among cations shows Na+ > Ca2+ > K+ > Mg2+ while anions exhibit similar distributions patterns where Cl- > SO4 2- > NO3 for both surface water and groundwater samples. Almost all the groundwater sample is characterized by types of saline water due to high content of chloride, sodium and high electrical conductivity value. The high concentration in groundwater could be due to location of study that situated on marine clay layer which have been intrusion with seawater. |
