Abstract

Data for aluminum concentration in Baghdad raw and drinking waterhave been taken from Baghdad Mayoralty for the period of the year (2005-2006)and for six water treatment plants (Al-Karkh, East Tigris, Al-Wathba, Al-Karama,Al-Qadisia and Al-Dora). The available data were analyzed by using statisticalprograms like (spss, statistica, grapher and excel) .Relation with water qualityparameters was obtained like relation with pH and temperature. From the studythe pH value was found to be ranged between (7.45-7.85) in supplied water forminimum aluminum residual. From the contour plot results show that an equationhas been concluded which connect concentration with pH and temperature.Seasonal variation was also studied; maximum concentration found to be insummer season, at Al-Karama and Al-Wathba water treatment plantsconcentrations were constant during the period of the study. Comparison betweenwater treatment plants was also made, Al-Qadisia and Al-Karkh water treatmentplants have the best control conditions, aluminum concentrations were found tobe within the Iraqi drinking water quality standards (0.2 mg/l).
