Groundwater in Dakhla depression is the only source of water wpply in most localities in the Western Desert of Egypt. Now a day, due :o the increase of the population, the groundwater development in the  epression becomes of great necessity, especially because the soil in the area is suitable for cultivation. For this reason, the hydrochernistry of :roundwater in the depression is studied to detect the quality of water. Thnsequently, this work is conducted to give an insight on the :eochemical aspects of groundwater in Dakhla depression, representing :Iferent aquifers of Nubian sandstone (Taref, Sabaya and Six Hills). In z e present study, the recharge sources and average recharge rates of Lroundwater of these aquifers are detennined and evaluated through the assessment of groundwater quality. Also, the objective of this work, is to aluate the hydrochernical data of groundwater of the different aquifers f the studied area and to assess the hydrochemical processes affecting ncr quality (leaching, dissolution, ion exchange, mixing processes, .idation reduction potentials, . . . etc.). Moreover, genesis, groundwater Eneralization and geochemical evolution are among the major targets. In :Jition, quality of groundwater and its suitability for drinking, domestic J irrigation uses are evaluated. Also, the pollution of water is studied  : :augh the determination of some minor and trace elements. The present study depends on a number of 120 drilled wells (50, 35 35 wells tapping of Taref, Sabaya and Six Hills aquifers. :oordingly, 120 wells tapping the different aquifers in the studied area
