Hydrogeochemical Studies on The Groundwater East Gabel El Qalamoon Area, Western Desert, Egypt

The Quaternary deposits of Pleistocene and Holocene cover the major part of the area under study, the Pleistocene deposits are composed of sand and gravels, and covered by Holocene unconsolidated silt and clay. The Pleistocene deposits represent the main water bearing formation in the area. Water samples were collected from 34 wellsin the area. The samples were analysised chemically for studying the water quality for the drinking and irrigation purposes. The hydrochemical studies show that the salinity of the groundwater ranges from 645 to 273170 ppm according to the locality of the studied wells. It increases in the western part of the area which is close to the Eocene aquifer water. The salinity and major ions are higher in shallow wells than deep wells. In some localities the groundwater can be used for domestic and irrigation purposes.
