A Study of Spring Water Quality and Its Suitability for Different Uses in the Area of Bartella – Eastern Mosul

Abstract

The water of the three springs in the village of Tarjla (located in the area of Bartala, eastern Mosul) is characterized by different physical and chemical properties depending on the results of the laboratory tests of (NTU, EC, TDS, TH, PH) and major ions (Na+, Ca+2, Mg+2, Cl-, ) for six selected water samples for the study area. This difference did not remain constant, but changed with the flow of water to the neighboring villages (Sheikh Amir, Shaquli, Karemlesh), where the percentages of physical and chemical concentrations have changed in terms of the increase and decrease of some water samples. This is due to the time factor and the water contact of some of the soils and rocks that encountered their flow as well as exposure to the sun. The purpose of the research is to study the quality of springs water to determine its suitability for different uses. Using the Piper and Stiff classifications, the water quality is calcium-bicarbonate, the calcium ion predominates over the rest of the positive ions and the bicarbonate ion prevails over the rest of the negative ions, this indicates that spring number (1) and spring number (3) are derived from the Fat'ha formation deposits, which contain limestone and gypsum rocks that contain high concentrations of sulphates. The spring number (2) is derived from the Injana formation and modern sediments that is hydraulically connected with each other and can be considered one reservoir. By comparing the results of laboratory tests with the international standards, it was found that the water of spring number (2) is suitable for human use, and that the water of spring’s number (1) and (3) are not suitable for human use because they contain a high proportion of sulfur ions. All water samples are suitable for agricultural and animal use and very good to excellent
