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.
