This study investigates the effect of continuous pumping on the quality and quantity of water supply in northeast Elobeid town, Bara basin in North Kordofan State, Sudan.

The principal objective of this study is to; assess the impact of Eelobeid water supply project on both the quality and quantity .The data used in this study includes lithological logs, pumping test, recovery data and monitoring water table levels information in addition to water quality parameters. Rock ware, surfer, Aquitest and aquichem softwares were used to analyze the data.

Based on the lithological logs from nine observation wells and seven boreholes in the study area, the geological formation was found tobe Umm Ruwaba formation composed of two aquifers one shallow and one deep aquifer. The transmissivity of the deep aquifer was found to be 0.176m² / min, which is good, and the average of hydraulic conductivity was found to be 0.0014m / min., which is high. High drawdown was seen in the production and observation wells resulting from the excessive pumpage.

The direction of flow of groundwater was found to be from North West to North East direction in the area. Chemical analysis showed that the average TDS concentration in the study area amounts to 375mg / l, which is within the permissible limit of the Sudanese standard and WHO.

The average of calcium concentration and iron were found to be 44.15mg / l and 0.258mg / l respectively, which are within the permissible limits of the Sudanese standard and WHO.

Average of nitrate concentration was found to be 74.1mg / l, which is above the permissible limit of the Sudanese and WHO standards. The water type in the study area was found to be calcium-nitrate-chloride-bicarbonate. It could be concluded that the quality of water in the study area is good for human consumption.
