The water quality index is an efficient way to assess the water quality of water sources and determine the validity of its use for various activities. The water quality guide (the Canadian model) was applied as an effective means in assessing the water quality of the Al-Haffar River within the city of Nasiriyah. Drinking water and for living purposes and for irrigation purposes in finding the values of the water quality index, which are: Air temperature Water temperature, flow velocity, electrical conductivity, total dissolved materials, salinity, turbidity, pH, total alkalinity, dissolved oxygen, BOD, total hardness, effective nitrate, reactive phosphate, sulfate, chloride, sodium, potassium, calcium, magnesium, boron, sodium adsorption rate, residual sodium carbonate, carbonate, bicarbonate, iron, lead, copper, bacteria, fecal colon. Principal Component Analysis (PCA) studies showed that iron, lead, biological oxygen demand, boron, copper, cadmium, fecal coliform bacteria, chlorine, total solids, and sodium are the most important variables responsible for the variance in the quality of drinking water, and thus the most determinant of the suitability of the river for drinking water supply. It was followed by calcium, total hardness, turbidity, effective nitrate, sulfate, magnesium, electrical conductivity, pH, dissolved oxygen and total basicity, respectively. All the variables were inversely correlated with the evidence used except for dissolved oxygen, total alkalinity, pH, electrical conductivity, magnesium and sulfate. While iron, lead, boron, cadmium, water temperature, the vital requirement for oxygen, copper and total solids were the most important variables responsible for the variation in water quality for living purposes, and thus the most determining the extent of the river’s viability for living organisms, followed by chlorine, effective phosphorous, turbidity, effective nitrate, pH and dissolved oxygen, respectively. . And that all these variables were inversely correlated with the evidence, except for dissolved oxygen, pH and nitrates. While boron, bicarbonate, cadmium, iron, lead, chloride and copper were the most responsible variables in influencing the quality of irrigation water, and thus the most determinant of the suitability of the Euphrates River water for irrigation purposes, followed by electrical conductivity, pH and sodium adsorption rate, respectively, and the remaining sodium carbonate had no effect on The value of the evidence because its values were imperceptible in the studies. All the variables were inversely correlated with the evidence except for the pH and the rate of sodium adsorption.Pages: 13-15 | Views: 298 | Downloads: 28Download Full Article: Click Here
