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 (...
