Groundwater is the second source of drinking and irrigation water in the study area, especially in the regions which lack of the surface water. Accordingly, twenty-five sample of groundwater have been collected from an area between of Abu Qurqas - Dayer Mawas districts and analyzed physically and chemically. The means of pH and TDS of the studied samples were 7.50 and 554 ppm, respectively. The majority of groundwater samples were fresh but very hard water. The groundwater high contents of the analyzed ions are attributed to leaching processes, the effect of marine sediments, agriculture drainage, sewage water, pesticides and fertilizers applications in the study area. The studied samples are earth alkaline water with prevailing sodium and bicarbonate ions due to ion exchange process of the rainfall which recharges the aquifers. Therefore, the majority of groundwater samples are of meteoric origin.
