In: Proceeding of 2nd Scientific Congress:the role of veterinary medicine in animal & environment protection: 29 -31 October, 2007Summary: Eighty (80) samples of ground water in Wady EL-Hyal, Libya have be studied to evaluate its Potability for human and animal consumption. The chemical anaIysis of the collected samples revealed that the mean values of nitrite, nitrate, chloride. sodium, potassium, calcium, magnesium and total hardness were 0.15,22.5,160.75,97.5,6.7,55.6,22.6 and 341.2 mgtl, respectively. The results also .showed that the mean values of iron, copper and lead were 0.47 mgtl, 0.31 mgll and 32.5 ug/l, respectively. The obtained data of bacteriological examination showed that the mean values of total colony count/ml, coliform count /100 ml and E. coli count /100 ml, were 82.2,40.2 and zero, respectively. High percentages of samples lay within the pennissible limit recommended by WHO except for iron, and total colony count where the number of samples lay within the permissible . limit were 66.5% and 60%, respectively. The hygienic significance as well as the sanitary measures suggested for preyention of chemical and bacterial pollution of ground water were discussed.
