GROUNDWATER DESALINATION USING MEMBRANE DISTILLATION AT THE AREA BETWEEN RAS ELHEKMA AND ELDABA`A NORTH WESTERN COAST, EGYPT

Abstract
ABSTRACT
El Daba`a area is located in the rid zone along the Northwestern coastal of Egypt, where the groundwater represents the major source for drinking and agricultural purposes. Over groundwater exploitation has detrimentally affected the groundwater quality. A field trip has been carried out to collect 45 groundwater samples tapping the two aquifers in the study area, where these samples were investigated and hydrochemically evaluated. The hydrogeochemical results demonstrate wide ranges of groundwater salinity and major ions in the oolitic Pleistocene and the fractured Miocene aquifer. The lower groundwater salinity has been recorded toward the south, closer to the Tableland plateau. On the other hand, groundwater of high salinity is located inland and near the Mediterranean coast due to the influence of seawater intrusion as a result of over-pumping. Based on the water chemistry and stable isotopes, groundwater recharge is limited and the main source for groundwater recharge is the annual precipitation. Higher groundwater salinity is mostly enriched in δ2H and δ18O due to mixing with seawater. The fresh groundwater occurs as a thin lens of freshwater which is very sensitive to pumping. Most of groundwater samples in the study area are unsuitable for drinking, livestock and poultry drinking, domestic & laundry uses and irrigation.
