The samples were collected randomly from 15 different locations in the city and analyzed using standard procedures. As a result of bacteriological analysis, all the fifteen treated tap water samples (100%) were positive for bacterial contamination. Isolation of coliform bacteria was confirmed and isolates were tentatively identified as Enterobacter sp., Citrobacter sp. and E. coli, at a percentage of 28.6% for each of them, and and Klebsiella sp. was comprised only (14.2%) from Al=Mugran and Al-Mamora water samples. As a result of chemical and physical analysis, EC, TDS, pH, Magnesium and Calcium Hardness and the Total Hardness, in all samples, were within permissible limits of World Health Organization ( WHO, 1995)
