The investigation of water quality index (WQI) and total coliform bacteria in water coolers water from various locations in faculty of applied sciences, UiTM Shah Alam / Azrena Azman

A study of water quality and bacteria analysis of water cooler water was carried out from various locations in faculty of Applied Sciences, UiTM Shah Alam. Water quality index was determined by specific parameters such as BOD, COD, DO, NH3-N, TSS, and pH. Results show, according to Interim National...
