Microbiological Quality of Drinking Water SupplyfromDifferent localities in Khartoum State

Abstract

The aim of this study was aseptically evaluate the Bacterial contamination of drinking tap water from different locations in Khartoum State (Khartoum, Omdurman and Khartoum North).A total of 150 samples were aseptically obtained for bacteriological analysis during the period from January toNovember2013. Water samples were analyzedfor E.coli, and total coli form, total count using membrane filter technique,Multiple-Tube fermentation Techniques a Pour plate count. Most samples obtained from Khartoum locality showed presence of total coliform18.93%, and fecal coli form21.27%,while those obtained from Khartoum North24.06% and53.61%, East Nile 14.99%,and 0%,Jabeel Aeolia3.94%,and 0%, Omdurman12.62%, and0%,Obadiah14.79%, and 4.68%, karri12.62%, and 20.42%.But water samples in all locations contained high number of total viable bacteria, Khartoum North3.38±0 CFU/ ml, East Nile3.79±0.86 CFU/ ml, Khartoum3.92±0.48 CFU/ ml,Jabeel Aeolia4.12±0.67 CFU/ ml ,Omdurman3.77±0.58 CFU/ ml, Obadiah3.93±0.49 CFU/ ml, Karri3.84±0.39 CFU/ ml. Data emphasized the fact that the Khartoum potable water supply has many microbial environmental problems, which may lead to series health problems for peoples. Therefore a need for intervention measures in order to reduce the burden of contamination.
