Abstract
Physical, chemical and bacteriological properties of drinking water and its quality index in Mosul University were determined. WQI was calculated through twelve parameters of tested results, this index usage in representation of the overall quality of water WQI for any intended use, drinking water samples were collected from eighteen sites in Mosul University, and analyzed to determined water quality parameters during summer 2008.
The study results indicated that al properties in safe international permissible limits for drinking water, except TPC which reached 800 cell/ml, the overall average of WQI reached 249; this high value belongs to high bacterial count which classified as very poor water.
