Origin of Springs at Najaf Area .South Western of Iraq
Abstract
Study area of spring's water is located at south western of Iraq in the Najaf city government between latitude (31º 00 ? – 32º 15 ? ) and longitude (43º 30 ? – 44º 30 ? ). The hydrogeology of area is explained two layers of groundwater. The first is resent deposits and the second is Miocene deposits. The second layer is important because of containment a big quantity of groundwater. Results show the classification for spring's water according to total dissolved solids (TDS) is slightly water to slightly brackish water and it was very hard according to total hardness.Also the results show the predominant salt is Magnesium Sulfate (MgSO4) and sodium chloride (NaCl) according to hypothetical salts in spring's water. The water type is sulfate according to predominate of ions in springs. Most of spring's water (70%) is Calcium Chloride (CaCl2) of marine water origin, while the minority (30%) is Sodium Sulfate (Na2SO4) of continental origin.
