ABSTRACT
Chemical analyses have been carried out for several groundwater samples
collected from 28 producing wells in the area east of the Nile and the
Blue Nile rivers, Khartoum State, Sudan. Three hydrogeochemical facies
are delineated: sodium-chloride-sulfate (Na-Cl-SO4 ), calcium-
magnesium-bicarbonate (Ca-Mg-HCO3 ), and sodium-calcium-magnesium-bicarbonate
(Na-Ca-Mg-HCO3 ). This study indicated that the groundwater
quality in the study area, which lies within the Nubian Aquifer, is fit
for human and agricultural purposes except at a few localities which contain
high chlorides, sodium and sulfates, as well as high values of electrical
conductivity above the permissible limits of the World Health Organization
standards. The groundwater is also fit for irrigation purposes except at
the same localities due to high salinity and a high concentration of sodium
ions.
