Abstract:
يعد نهر الفرات المصدر الاساس لمياه الانشطة المنزلية والصناعية والزراعية في محافظة المثنى، وذلك بسبب انتفاء او ندرة مصادر المياه الاخرى. وقد اهتم موضوع هذه الدراسة بالتعرف على الاملاح الذائبة المتواجدة في مياه النهر، ووصف المصادر الرئيسة لتلك الاملاح ولاس | Due to scarcity of other water resources, Euphrates River has been considered as a fundamental source of water used for domestic, industrial and agricultural purposes all over Muthanna Governorate. The study has concerned a number of objectives such as identifying the particular salt melted in the river, describing its main sources ( in particular these of high level) and to discover the interrelation between melted salt and water quality to determine the convenience of various usage. Four different sites are distributed Along the Euphrates River where (16) samples of river - water as well as (2) samples of waste water haven been taken during the four year season. Accordingly, various laboratory tests have been done to investigate physical and chemical properties. These include the total dissolved salt (TDS), electric conductivity (EC) in addition to main cations and anions. Both of Shatt Al - Atshan and Samawa sites indicate highest concentrations of (TDS) in comparison with Shatt Al - Saable and Al - Khudhir sites. Generally, in comparison with global average, Euphrates River is well known of its high ionic composition. It can be said that Sodium dominates the cations as well as Chloride dominates the anions. Throughout Muthanna governorate, agriculture activities together with Al - Atshan stream have been considered the main sources of melted salt in Euphrates River. Whilst, the chemical composition of the river is clearly affecting by river - draining, ground water - flowing as well as dissolved gypsum and lime stones along with activities of aquatic organisms. As a matter of fact, the dissolved salt has affected the quality of river - water and its hygienic usages. In line with WHO, FAO and Iraqi standard measurement have indicated that the river - water of the mentioned four sites is not useful for the purpose of drinking and irrigation, yet it is proper for livestock and poultry. However, this water is not beneficial for industrial usages
