Awad, M. Hamza, S. Atwa, M. Sallouma] The groundwater resources of the El-Qusier-Safaga area on the Red Sea coastal zone have still to be utilised fully for social and economic development. In the present study, an inventory of recharge sources and quality of groundwater in different water bearing formations is made to assist in management of these vital resources. From a hydrochemical point of view, the origin of salinity in the five investigated aquifers are mainly dissolution of terrestrial minerals, leaching of soilsvia floods or ion exchanges processes. Stable isotope data clarify the interaction between different aquifers and indicate that the source of recharge is mainly meteoric water originating from palaeowater of the Pleistocene pluvial period, and from local precipitation as well as some marine water. Evaluation of the groundwater quality for domestic, irrigation and industrial purposes is discussed.
