Evaluation of Bacterial Contamination in Drinking Water at White Nile State, Sudan during 2022-2023

The ecosystems in Sudan are divided into aquatic and terrestrial habitats. The biodiversity including description of status of ecosystems and populations. The aim of this study was to evaluate of Bacterial contamination in drinking water at White Nile State (Kosti and Rabak Cities) during February 2022 and October 2023. Five random sample of drinking water were collected from each City. The quantity was 250 ml and were collected in 250 ml clean and aseptic plastic container. This test was conducted in the Microbiology Laboratory, Faculty of Engineering and Technology, University of Gezira. The technique used was the direct pour and spread plate count method, using 1.0 ml of the drinking water and agar media selective to coliform bacteria. The results showed that, the quality standard for this bacterium was zero in both cities during the whole study periods. The contamination with E. coli observed to be gradually increased each season. Rabak drinking water was significantly contaminated with E. coli more than Kosti. The quality evaluation for the drinking water, whatever the city, should be routine work, and the pollution sources should be detected and treated immediately.
