الملخص EN

The present study included the water quality of the drinking water from Bradiiya and Al – Abbas water project supply during the period November 2006 - July 2007 , to consumer and the determined the treatment efficiency in order to view its acceptability for drinking and other domestic uses.

The study involved :Temperature ,Color,Odor ,Tast ,Turbidity , pH ,Electrical conductivity ,,Salinity , Total Dissolved Solid&Total Suspended Solid , Dissolved Oxygen & Biological Oxygen Demand ,Carbon dioxide ,Total Alkalinity &Total Hardness , Ca & Mg Hardness ,Chloride ,Total Residual Chlorine , Sulphate ,Sodium ,Potasium, Nitrite ,Nitrate, Silica and Phosphate, Aluminum , Iron ,Copper &Zinc , which affect water quality .

Also the study was included the biological parameters which involved Bacterial indicators of polluted water (Total Coliform & Fecal Coliform bacteria), and phytoplankton (quantitative study ).

The physical , chemical and biological results obtained from the present study showed that supplied water that pumped from Al-Bradiiya water project and to some extent also from Al-Abass water project , were un acceptable compared with local and international standards .

However , in case of dissolved trace elements , the mean values of element studied (Aluminium, Iron, Copper and Zinc) almost within the acceptable levels.
