Abstract

The Tigris River is one of Iraq's most important water resources; therefore, its water quality must be monitored continuously, especially from an environmental perspective. The current study aimed to evaluate the quality of Tigris River water in Mosul before entering the filtered Tigris River water and after the Tigris River water exits the Qayyarah filter. Water samples were taken in September, November, January, and March at a rate of one sample per month to study some physicochemical properties such as acidity, temperature, electrical conductivity, total dissolved solids, turbidity, total hardness, calcium and magnesium hardness, sulfate, nitrate, fats and lipids, biological oxygen demand, chemical oxygen demand, lead, and cadmium. Some physical and chemical properties were within the recommended Iraqi disposal limits for 2009, except for turbidity, biological oxygen demand, total hardness, calcium, magnesium hardness, and lead and cadmium, which exceeded the recommended Iraqi disposal limits for drinking water for 2009.
