Assessment the Quality Number of Well Water on the Left Side of the City of Mosul / Iraq and its Suitability for Drinking Using the Canadian Water Quality Index.

Abstract

The current study was conducted on 10 wells of water located within the city of Mosul / on the left side. The quality of this water was evaluated to determine the number of physical and chemical properties, including acidity, turbidity, total dissolved salts, total alkalinity, nitrates, chlorides, phosphates, calcium, magnesium, and sulfates. The current study showed that the values of total dissolved solids and sulfate rates for well water ranged between 155-1150 mg/L, and 226-1037mg/L, respectively, and the acidity function rates ranged between 7-7.6, which are within The appropriate determinants of drinking according to the specifications of the World Health Organization, while the average values of turbidity ranged between 0.5-21 N.T.U, and the nature of the geological formations of the study area had an impact on the concentration of calcium and magnesium, as well as the chlorides and total alkalinity where the concentration rate ranged Between 29-325, 16-89, 20-259 and 179-366 mg/L, respectively. The results of the current study showed that wells water for drinking purposes, according to the Canadian Water Quality Index (CWQI), varied between (doubtful -good).
