Qualitative Evaluation of Selected Well Water from the South Areas of Tal Afar District in Nineveh Governorate / Iraq for Various Civil Uses

Abstract

The study included the random selection of water from five wells from the southern districts of Tal Afar district to assess its quality and determine its suitability for drinking purposes and various civil uses by studying the physical and chemical properties (temperature, total solid dissolved materials, pH in addition to positive and negative ions) and applying the water quality index (WQI). The results of the current study showed that the water temperature was relatively constant throughout the study period, while the values of total dissolved solids (TDS) ranged from 1186 mg/l in the well (1) to 1859 mg / l in the well (5) While the concentration of dissolved oxygen decreased to an average of 1.2 mg/l in well (1), while the values of total hardness and sulfate increased to the limits of 1530 mg/l and 840 mg/l, respectively, and the nitrate values ranged between (1.2 - 13.8) mg / l and A Phosphate values ranged between (1.33-0.02) mg / l due to its adsorption with minerals in the rocks around the groundwater, and the results of the water quality coefficient (WQI) indicated that the values ranged between (109-125), and the studied was considered to be of poor quality for drinking purposes and various household uses due to the high values of total dissolved solids (TDS) and sulfur for the studied well water.
