Application of Water Quality Index and Water Suitability for Drinking of the Euphrates River within Al-Anbar Province, Iraq

In this study water quality was indicated in terms of Water Quality Index that determined through summarizing multiple parameters test results. This index offers a useful representation the overall for public or any intended use as well indicating pollution, which are management and decision making. The application (WQI) with ten physicochemical performed to evaluate Euphrates River drinking usage. done by subjecting samples collected from seven stations within Al-Anbar province during period 2004-2010 comprehensive analysis. included: pH value, Alkalinity (ALK), Orthophosphate (PO4-3), Nitrate (NO3-),Sulphate (SO4-2), Chloride (Cl-), Total Hardness (TH), Calcium (Ca), Magnesium (Mg), Dissolved Solids (TDS). average annual WQI found be 107.59 period. high obtained is result concentrations can attributed various human activities taking place along river banks. From analysis classified "very poor quality" ranging at upstream near station (E1) unsuitable downstream (E7) an minimum 89.34 2008 maximum 112.44 2009. present demonstrated estimating understanding River. appears promising valuable tool categorizing pollution sources surface waters
