Abstract

The physio-chemical characteristics and chemical composition of the Sawa lake water ,well water  ,and Al-Atshan river water  (branch of the Euphrates river ) were studied for determination the ionic composition of water samples .The type  of water in Sawa was  Mg- chloride ,It shows   hydrochemical characteristics similar to  Al-Atshan river rather  than the well water  near by or sea water .Its water could be subjected to  mixing with  fresh and groundwater of marine origin. The water in the lake and that  at   the  Euphrates river  are similar in hydrochemical characters. Based on terrestrial   water exchange with  marine origin sediments, Sawa lake water  is over saturated  with calcite, dolomite , aragonite ,gypsum and anhydrite minerals.
