Determine the validity of the Euphrates River (middle Euphrates)‎ for drinking purpose using a water quality index (CCME WQI)‎

الملخص EN

The current study conducted to assess the Euphrates river (mid Euphrates) for drinking purpose adoption of water quality Index-Canadian model-as an effective means to identify the water validity of various purpose, as has been selected four sites and samples were collected from these locations for the period between May 2013 to April 2014 and its conducted some physical and chemical tests, which included : pH, turbidity, electrical conductivity, total alkalinity, dissolved oxygen, Biochemical oxygen demand, calcium, magnesium, chloride, total hardness, sodium, nitrates, nitrites, sulfates, boron, total coliform, lead, copper, zinc, cadmium, manganese and chromium.

As used Principal Component Analysis (PCA) to determine the greatest physical, chemical and biological factors that influence in the Index and causing the deviation of it from normal values.

The result of PCA confirmed that physical, chemical and biological variables have different effect in all sites of study area on the Index values whose ranges between71.83-36.4 that indicates Euphrates in the study area has the Fair-Poor quality.
