المستخلص: SM;thesis titled (Water Pollution in Euphrates, Thi Qar Go~morate Environmental Geography Study) includes an experiment to Euphrates water in Thi Qar Govemorate of pollution after making a n•riofchemical and physical tests, water was tested for the period from 2006 - 2007 throughout relating the polluted concentrations for the river with rates of water discharge which differ according to the diff~nt of seasons. "five sites were specified within the study area are different. spatiaJ,ly, and picking up samples during the four seasons which include the water of Euphrates and others of its bottom sediments. Then the results wer~ shown and evaluating the river's water regarding these results throughout using the water for different human purposes include drinkingp~ti*elS·,1'.ndustrial and agricultural usages (Irrigation). !he content of the study has four chapters and introduction. First , chapter discusses hydrological study for Euphrates water from its high sources in Turkey passing in Syria and Iraq till the area of the study expJaining the main problems leads to change quantity features and quality of its water. Second chapter deals with the natural factors in area of the stuqy, which has an effect on changing characteristics of river's water.. Thitd c~pter discusses the human factors which lead to pollution of Euphrates' water within Thi Qar Govemorate represented by dirt of civil sewage, industrial, drainage water and fertilize' rs used in agricultural field.Fourth chapter has a number of chemical and physical characteristics for water and sediment of Euphrates that that results shows an increase in co¢entration proportion for each of (Tran, Si02, Mg, P04, CL, Tur, TH, Ee), which exceed environmental limits for their concentration accol.'ding to Iraq Standard of Water Environment. The concentration proportion of (N03, Do, TDs, HC03, Ca, S04, PH) are within the environmental limits for their concentration.The results of bottom sediments of Euphrates for (TOC, EC) exceed environmental limits for their concentration, but the value of PH is within these limits but. it is distinguished of alkalinity. So, Euphrates water was polluted and it is not good for human usages (drinking), as well as it is not suitable as water used for industrialization, except cooling purposes, also is not proper to use this water in irrigation because it is classified within C3 Type of irrigation water types in the American Laboratory and it is of highsalinity and it doesn't use in the case of existing active drainage networks, high penetration soils and agricultural crops have the ability to resist the salinity.
