Study of Raw Water Pollution and its Impact on Water Supply Quality of Al Qasr Water Treatment Plant / Northern Iraq

Abstract

The present work included the study of Tigris River raw water, supplying Al-Qasr water treatment plant, 15km south of Mosul city, Sulfate water spring near the station were also studied. Field observation together with chemical analysis suggested that the area of study is affected by the water of sulfate springs, resulting in high concentration of major cations and anions of the water of the station. Trace elements, like (Cd, Cu, Fe, Mn, Ni, Pb and Zn) also showed relatively high concentrations The treated water of the plant is out of the recommended of the international standards of drinking water, to evaluate its water quality for human consumption. They are polluted with the heavy metals mainly (Cd, Ni and Pb).
