    The purpose of this study was to assess bacteriological, physical, and chemical quality of drinking water distributed at Khartoum metropolitan state, in order to ascertain water quality for human consumption. 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)

    Evaluation of the Drinking Water in Khartoum North Municipality
    (جامعة النيلين, 2017) El fadil, A. G.; Muzdalifa O. A.; Ahmed MahgoubHamed
    Abstract—The aim of this study was to assess the bacteriological, chemical and physical quality of the drinking water distributed at Khartoum North Municipality, in order to ascertain water quality for human consumption. Five samples ( in triplicates) of tap water were collected randomly from five different locations in the municipality, namely; Al-faihaa, Al-mogtarbin, Shambat, Al- Kadaru and Alwosta, water samples were analyzed using the standard procedures. The results of the bacteriological analysis revealed that all the five treated tap water samples (100%) were positive for different bacterial contaminations. Isolation of coliform group bacteria was confirmed, the isolates were then tentatively identified as Enterobacter sp., Citrobacter sp. E. coli, and Klebsiella sp. Klebsiella sp. was found only in Shambat water sample. 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) and Sudanese Standards and Metrology Organization (SSMO, 2006), whereas, some parameters were out of the standards as The Total Alkalinity at Alwosta, also the Turbidity in Al-mogtarbin was a little higher than the standard limits. Calcium Hardness in Al-faihaa andAlwosta was higher than the standard limits and it was found that the Free Chlorine in all water samples was quite low than the recommended level, which ensure the prevention of the further contamination.
