WATER QUALITY OF TIGRIS RIVER IN JADRIYAH DISTRAC OF IRAQ

The Tigris River, which is the second-longest river in Western Asia, passes through densely inhabited areas, particularly in Baghdad, which is inhabited by nearly 8 million people. The Tigris flow has declined significantly over the past few decades, and this, together with rising wastewater volumes and wastewater treatment. Three sites were chosen, in this paper water quality evaluation is carried out in the Jadriyah area of Iraq and analyzed for various physicochemical parameters. These sites were close to many residential and commercial buildings and the presence of electrical power generation stations. These samples were analyzed laboratory and field using internationally approved methods. This study was designed to determine the amount of pollution in this area according to the standards of the WHO and the Iraqi Ministry of Environment. The results indicated that the third site in the study had the highest percentage of ions. The sodium level in this site reached about 130 mg/l and 128 mg/l in January. Likewise, for the phosphate compound, the highest value recorded in the third site was 0.187 mg/l. The presence of these ions in abundance in this site, in addition to phosphate compounds, which are considered one of the most important plant nutrients, helps the growth of plants such as algae, and this leads to an increase in oxygen consumption at the site and reduces water quality. The results of this study are worrying, but they also contribute to a better understanding of the factors the water quality and can help authorities and stakeholders with sustainable development.
