Investigation of surface water quality and degree of hardness at Semenyih Dam, Selangor / Norfadzilah Abd Rahim
Semenyih Dam is one of the Klang Valley major dams in Malaysia which is an important water resource. Water quality is important because they help to protect and restore of the quality of surface water that is suitable for human use. The objectives of this study are to determine Water Quality Index (...

Water quality is important because they help to protect and restore of the quality of surface water that is suitable for human use. The objectives of this study are to determine Water Quality Index (WQI), water classification and to measure the degree of water hardness for surface water at Semenyih Dam.

Water Quality Index (WQI) was calculated based on 6 parameters which were Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH, Total Suspended Solid (TSS) and Ammoniacal-Nitrogen.
