EVALUATION OF ENVIRNMENTAL IMPACT OF TIGRIS RIVER POLLUTION BETWEEN JADIRRIYA AND DORA BRIDGES

摘要：

The raw sewage discharges of A1-Saidiya (PN) pumping station forms the major pollution source to the river in the southern part of Tigris river within Baghdad city, its main importance comes from its location upstream to A1-Dora water treatment plant and to the river hydraulic characteristics represented by the sharp U-shape bend.; the cloud of pollutants while training along the river creates a visual and malodorous nuisance to the region. It was found that most pollutants concentrations at AI-Dora WTP range within the permissible level for Iraqi raw waters; with the exceptions of Coliform and Feacal Coliform that are highly above the limits; SO4 and BOD showed some high values. As a short term solution to the problem it was proposed to change AI-Saidiya outfall location and structure to be a bed release on the outside river bank instead of the actual surface release, in order to promote mixing and hence minimizing the impact of pollutants.
