INVESTIGATIONS OF SOME HEAVY METALS OF GROUNDWATER AQUIFER OF WADI EL NATROUN AREA IN EGYPT.

In Wadi El Natrun depression the Pliocene aquifer receives inflow of Miocene and Pleistocene aquifer waters and from the agricultural activity and septic tanks. Groundwater samples were collected from 25 water wells and seven principle salt lakes at Wadi El Natrun area. Heavy metal (Cu, Zn, Mn, F, Cr, Ni, Cd, and Pb) concentrations of Wadi El Natrun aquifer were investigated. The determination of trace metals (Cu, Zn, Fe, Mn, and Pb) has been performed in order to study environmental pathways. Evaluation of Groundwater of the Pliocene Aquifer for Drinking Purposes According to International standards for the quality of drinking water The Samples that are away from the saline lakes are acceptable water for drinking but the samples which are close to the saline lakes permissible water for drinking.
