Comparisons of water quality and heavy metals concentration between Lata Janggut and Lata Keding, Jeli, Kelantan

Water quality becomes a concern issues because low water quality can affect to organisms and ecosystem Therefore, a study was conducted at two sites which are Lata Janggut and Lata Keding that being attraction to community at Jeli District. The main objective of this study was to determine water quality index and classification at the cascades, also to determine physical parameters which are pH, Total Dissolved Solids (TDS), Salinity, Dissolved Oxygen (DO), and Electric Conductivity (EC) by using Multiparameter (YSI), while for chemical parameters are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammoniacal Nitrogen (NH3N), and Total Suspended Solids (TSS) by using HACH DR6000 UV-VIS Spectrophotometer, same goes to selected heavy metals; zinc, copper and iron. This research provides information about water quality data at Lata Janggut and Lata Keding, as a future reference for any agencies and community uses. 12 samples were collected from each of two points; flowing water and stagnant water area for two times sampling (July and August). Water Quality Index (WQI) of Lata Janggut was analyzed with 69.07 (Class III), and Lata Keding with 71.75 (Class III), according to the WQI value suggested by DOE of Malaysia. Therefore, Lata Janggut and Lata Keding was still in good conditions, but further monitoring is needed to avoid any environmental issues occur.
