Abstract

This study was conducted to assess the quality of drinking water in the public network in some areas of Wadi –Shati. It included 10 samples with three replications for each sample from the areas of Ashkeda, Qaira, Barak, Tamzawa, Al-Qarda, Burqin, Wonzrek and Idri. The results of physical, chemical and bacteriological analyses showed a difference in the quality of drinking water. The results of turbidity in water supplies distribution system ranged from (0.5 - 7  JTU) and the values pH ranged between (6.47 - 7.37), while the concentration of total soluble salts, total hardness, calcium, magnesium, sodium, potassium, chloride, nitrate, sulphate, bicarbonate, iron, manganese, zinc, copper ranged from 648 – 1523, 52 – 224, 11 – 37, 2 – 33, 26 – 112, 17- 34, 121 – 540, 3 – 33, 29 -  695, 46 – 78, 0.03 – 2.77, 0.07 – 2.07, 0.0 – 1.0, 0.0 – 0.026 mg/l respectively. While all samples were free of lead, the total number of bacteria ranged between (7 - 65 UFC/ ml); all samples studied were free from coliform bacteria.
