Bacteriological evaluation of the drinking water quality in Khartoum State, Sudan

الملخص EN

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 Khartoum bacteriological analysis during the period January November2013.

Water samples were analyzed for 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 state showed presence of total coliform , and fecal coli form, while those obtained from Khartoum North 24.06% ,and 53.61%, East Nile 14.99%,and 0%,Khartoum18.93%,and 21.27%, Jabeel Aeolia3.94%,and 0%, Omdurman12.62%, and 0%, Ombadah14.79%, and 4.68%, karri12.62%, and 20.42%.

But water samples in all locations contained high number of total bacteria, Khartoum North 3.38±0 CFU/ ml, East Nile 3.79±0.86 CFU/ ml, Khartoum 3.92±0.48 CFU/ ml, Jabel Awlia 4.12±0.67 CFU/ ml, Omdurman 3.77±0.58 CFU/ ml, Obadiah 3.93±0.49 CFU/ ml, karri3.84±0.39 CFU/ ml.

Therefore a need for intervention measures such as in order to reduce the burden of contamination caused by coliform bacteria, in the area of study is contamination is above the normal level?.
