Abstract: 

This study deals with new reclamation areas in East Beni Suef and El Minya governorates, Its identified by two types of aquifers, top one Quaternary aquifer and deeper one Eocene aquifer. The study confirmed the relationship governing the groundwater movement with geological structures. Where faults trends coincided with the groundwater movement. The hydrogeological survey of the area indicated that the aquifer discharges its waters through hundreds of existing wells for irrigation and agriculture. Eocene aquifer consists of deposits of limestone, groundwater depths ranges between 70 m to 95 m, the discharges range between 6 m3/hour and 30 m3/hour, The mean depths for drilling wells range between 180 m and 200 m., The transmissivity ranges between 2.47 m2/day and 1248.7 m2 / day.  Groundwater salinity ranging between 1000 ppm. and 3300 ppm. , the highest groundwater salinity in the central region and near the River Nile, while decreases as we go north, south and east. The prevailing salt in groundwater is sodium sulphate which represents 43% of the total salts in groundwater .Interpretation of chemical analysis indicated the presence of groundwater source deeper than Eocene aquifer, it may be Nubian Sand Stone Aquifer (NSSA).
