Bacteriological and Physical Analysis of Dug Wells in South Darfur (Tolus town) for Indication of Pollution by Enterococus E. faecalis and Coliform

The provision of safe and adequate water supply for the population has far reaching effects on health, productively and quality of life, as well as socio-economic development of the nation. The present study was undertaken to determine bacteriological quality of water sources in Tolus town, South Darfur state west Sudan. Water samples from fifteen randomly selected, unprotected dug wells were collected during rainy season (2001) and transferred and analyzed in Nyala veterinar research laboratory (N. V. R. L). Presumptive coliform test for determination of most probable number ( MPN), followed by a physical confirmatory tests. Where, the investigation revealed that the number of bacteria is inversely proportional to Reynoldss number that is obeyed the laminar flow, which confirm the biological results. The investigation revealed that all the studied water sources were contaminated with faecal bacteria and have presumptive bacteria count above the permissible limits for sanitary water, recommended by (WHO, 2008).
