Abstract

This study was conducted to achieve several objectives that determine the value of the parameters that were studied based on Water Quality Index (WQI). The parameters include Dissolved Oxygen (DO), pH, Biochemical Oxygen Demand (BOD), Ammoniacal nitrogen, Chemical Oxygen Demand (COD) and Suspended Solids. In this study, Sungkai River, located in the state of Perak, Malaysia was selected as the sampling area. There are a few villages located near the river area. Sungkai river is a famous spot for water and family activities such as kayaking, rafting, camping, bathing and many others. Through the researcher’s observations, several pollutions were found occurring along the research area such as the disposal of waste water directly from the villagers, widespread dumping of solid waste and the development of the surrounding areas that contributed to the pollution of the river. Results from the experiments showed that the Water Quality Index (WQI) result for Sungkai River is 72.5 and classified under class III which is safe, specifically for fishery and livestock drinking but it is slightly not so suitable to be used for recreational and bathing purposes. In addition, the water is not drinkable by human and extensive treatments are required. This category is based on the experiments results and referred to the Interim National Water Quality Standard for Malaysia (INWQS). As a recreational spot for the locals and tourists, the activities that could lead to the pollution of the Sungkai River need to be prevented and overcome. Therefore, there is a requirement to investigate and analyse the water quality of all rivers in Malaysia focusing especially on the area of water activities. This study can provide a good outcome on the water quality of the rivers, hence, actions can be taken to overcome any problems regarding river water quality for the safety of all.
