| Abstract | ||||
| The current study examined the quality of raw Tigris River water used in water purification plants located on both sides of the river within the city of Mosul. Monthly water samples were collected from sites within the New Right Water Project purification plant. A range of physical, chemical, and biological tests were conducted on these samples. The results revealed clear variations in the measured values and concentrations over the study period and across the sampled sites. In October, the water quality parameters recorded the following average values: water temperature at 21.15°C, total dissolved salts at 206.44mg/ L, electrical conductivity at 413.11µS/ cm, turbidity at 7.38 NTU, and pH at 7.50. Additionally, the concentrations of total hardness, calcium hardness, and magnesium hardness were 78.44, 28.62, and 49.82mg/ L (as calcium carbonate), respectively. The concentrations of major negative ions were also measured in October, with nitrate at 0.18mg/ L, phosphate at 0.22mg/ L, sulfate at 24.86mg/ L, and chloride at 7.99mg/ L. | ||||
