Study of Some Physical and Chemical Properties of Some Wells' Water in Qalat Sukkar / Dhi Qar Governorate - Southern Iraq

Abstract

Due to the lack of hydrogeological studies in Qalat Sukkar / Dhi Qar, it was selected for the study. Eight groundwater wells were selected as the second water source in areas that don't have liquefaction services or don't contain creek coming from Al-Gharraf River. Well water samples were collected on 3/28/2021. (1)liter of water was taken from each well and placed in (1)liter plastic bottles and kept in the refrigerator. Some physical and chemical properties (pH, turbidity, electrical conductivity, Cl- , TDS) of water were studied by analytical and electrical methods in the laboratories of the Department of Soil Sciences and Water Resources-College of Agriculture/University of Sumer. pH values recorded a significant change, the highest value was 8.223 in W6 and the lowest value was 7.713 in W3. EC ranged from 2.45 to 11.570 mmhos/cm. The lowest amount of TDS w was 1568ppm and the highest value was 7404ppm . Well water was classified as medium salinity according to Bouwer classification. The highest value of chlorine was 41.850meq/L and the lowest value was 3.5meq/L. Turbidity was between 2.18 and 101FTU. After comparing our results with the WHO standard specifications and the Iraqi specifications and the international physical specifications for drinking water and Altoviskig specifications for water for animal consumption and Ayers and Westocot classifications, and Scofield classification for the evaluation of water for irrigation purposes, it was found that the water is not suitable for human consumption for drinking purposes, It is also suitable for irrigation and animal consumption.
