ASSESSMENT OF SHATT AL ARAB WATER QUALITY USING WATER QUALITY INDEX ANALYSIS
Water quality index (WQI) is a unique value indicator used to assess overall water quality in a single term. [1]This study aims to assess the water quality of Shatt al Arab (south of Iraq) for drinking purposes for the period 2014-2018 using the weighted arithmetic WQIR method. Samples were taken from five monitoring stations on Shatt al Arab and fourteen physical and chemical parameters were analyzed. Spatial analyses were done using the Geographic Information System (GIS) to map the water quality index results. More river parts were found to be between good and poor qualities in 2014 whereas all of them were unsuitable for drinking in 2017 and 2018
