Over much of omdurman area groundwater represents themain source for the domestic water supply as well as for the limitedagricultural and industrial activities.This study was conducted in Omdurman city, which include,Omdurman, Karrari and Ombada localties, during the period fromAugest 2006 to March 2007.15 Boreholes were selected in the study area. These aredistributed according to localities.The target samples were distributed in Omdurman, Karrari andOmbada localties, and were collected from Boreholes, Storagefacilities, houses and Vendors, which are feeding the houses notconnected to the network, samples were taken for laboratoryanalysis, which included chemical, physical and bacteriologicalexaminations.The results of the study showed that, the majority of boreholesin study area were safe regarding chemical quality aspects. Thisincluded (F- NO2- NO3- CL – pH - TDS);the concentration of theseparameters were within the allowable limits set by (WHO) and(SSMO).The samples taken from Elshab factory boreholes recordedhigh level of chlorides 7250mg/l, exceeding the maximumpermissible level of 250mg/l, and TDS values, equaling 1023mg/l,were also more than the maximum permissible level of 1000mg/l indrinking water.Assessment of Groundwater Quality in Omdurman City12The results of physical quality of water samples, taken fromthe study area, were acceptable.The bacteriological analysis of the water samples taken fromthe boreholes in the study area recorded higher level ofthermotolerant and Ecoli, (46%) were more than the permissiblelevels set by (WHO) and (SSMO) standards.The results of samples taken from the Storage facilities showed that(66.7%) of these facilities were safe (not polluted).As for the Bacteriological quality of water samples taken fromHouses, samples were found to be polluted by Ecoli andthermotolerant coliforms.It was observed that the contamination rate of water in houses whichare not connected to the net work was (62.3%) higher in comparisonwith those directly connected to the net work. This demonstrates theimportance of distribution system in alimentally the contaminationrate.This study comes out with many suggested recommendations,the important of which are that the pollution sources should be sitedaway from boreholes, Septic tank and latrines should be of properdesigns to eliminate infiltration to boreholes through soil layers.Also disinfection of wells is important. On the other hand legislativeacts and regulation for well drilling and proper disposal of effluent isof high importance.Assessment of Groundwater Quality in Omdurman City13• Health education and awareness to consumers should beprovided regarding protecting and conservation of waterin houses.• Connect all houses in the study area to the public network of drinking water.• Encourage research in groundwater quality in order toprotect, monitor and control pollution.• Establish ground water conservation programme.
