Study Of Aluminum concentration levels in Tigris river , Drinking water Treatment Plants and supply network in Nineveh Governorate

AbstractThis study has been done due to the raising importance of aluminum in drinking water from health point of view. Survey of Al+3 concentrations has been done in Tigris river, in the water purification plants and water supply network. These plants are the larger ones in the city ( unified right side plant, Al-Qubba plant, the old left side plant ( Al-Arabi restrict) and Al-Danadan complex project). Results revealed that the Al+3 concentration on the river (through Mosul city) ranged from 7-37g/L. The plants have increased this concentration in raining times (turbidity increasing times) to about 25-50 g/L (ppb), because of adding alum in its work. Water distribution network does not affect the residual Al+3 in this study. There was a correlation between Al+3 and temperature. Finally, it can be said that Al+3 concentration in drinking water is in the safe side according to several international health organizations if the plants do not add alum.
