Ecological study of some physical and chemical parameters of Al-Gharraf river and one water treatment plant in Wasit province, Iraq

Abstract

This study was conducted to measure some of physical and chemical parameters for Al-Gharraf river water and water treatment plant (Al-Karimmia water treatment plant) in Wasit Province from May 2017 to October 2017.Ecological factors that measure included water temperature, turbidity, pH, electrical conductivity , total dissolved solid, total hardness, alkalinity and the concentrations of (Ca,Mg,SO4,Cl,Na,K) for the samples of the raw water from river water and drinking water from water treatment plant and compared drinking water with Iraqi standards to determine its suitability for human uses. The results of this study of the raw water showed that water temperature was in the range(23-34.7Co), turbidity in the range(35-123 NTU),EC and TDS ranged between (1018-1343 μs/cm) (640-864 mg/L) respectively. The range of pH (7 to 7.5),total hardness (335 to 448 mg/L) and alkalinity (158 to 197 mg/L). The concentrations of Ca and Mg in the range (72-115 mg/L) (33-47 mg/L) respectively. The monthly concentrations of sulphate ranged between (200 -320 mg/L) while the concentration chloride (91-119 mg/L). Sodium and potassium values varied from (78-107 mg/L) (2-3 mg/L) respectively. The physical and chemical parameters such as water temperature, turbidity, pH, electrical conductivity , total dissolved solid (TDS), total hardness, alkalinity and the concentrations of (Ca,Mg,SO4,Cl,Na,K) were measured for drinking water and all of these agree with Iraqi standards.
