Microbial Analysis and Safety of Drinking Water in Northern and Southern Darfur

Osama SeedAhmed Karrar, Muna Agab, Ahmed Eltiny

Abstract


Twenty four samples of drinking water raw and treated {16 from Northern Darfur (ND) and 8 from Southern Darfur (SD)} were collected at random. The sources of water included wells, dams, hafirs, water stations, and rest houses. Microbial analysis included total bacterial count, Coliforms and fungi. Drinking water microbial analysis showed that well (4) and (5) free from Coliforms, thermo tolerant E. coli, total bacterial count and fungi. They are suitable for human consumption according to WHO and Sudanese Standards of Drinking Water. Values of Coliforms were high for wells (1, 2,3,6,7 and Shigrat Elwadi (Tendulti) deep well), Dams 1and 2, Maleet village and government rest house with Coliforms range of 0.5- 6.5/ml. water is not fit for human consumption.

Microbiological analysis of Coliform of raw water drawn by hand pump from deep wells in Hay El Gabal, Hay Elganayin and Yau yau shallow wells Rope and Bucket ranged 1.2/ml-7 Coliform and is not suitable for human consumption.

Water from Manawashi Hafir, Goz Badeen Rahad, Nyala Khor, Nyala Water Station and Nyala Government House had high Coliforms range from 3/ml- 25.5/ml. it is not suitable for human consumption according to WHO and Sudanese Standards. In spite of this fact out- break of serious water borne- diseases had never been reported.

It is observed that microbiological analysis of sample of drinking water from wells (4) and (5) of ND are the only sources meeting the WHO and Sudanese Standards for indicator organisms. The rest of the samples of water collected from different sources in ND and SD need treatments for their suitability for human consumption according to international and national microbiological standards.
