Applying Water Quality Index Technique to Estimate Tigris Rivers Stability for Drinking in Saouira North Wasit Government, Iraq

In the present study water Quality Index has been used to assess suitability of serves water quality for drinking purpose in Saouira area. Service water samples were collected in September (2015) and April (2016) from nineteen samples have been modeling analysis in General Commission for Ground Water the analyzed for their physicochemical characteristics such as pH, total dissolved solids, Electrical Conductivity, sodium, calcium, magnesium, potassium, bicarbonate, sulphate, chloride, total hardness and nitrate. Each parameter was compared with its standard permissible limit as prescribed by Iraqi drinking water standards. The results showed that WQI values for the serivec water of the study area ranged from 47.36 to 52.63. Based on the WQI classification majority of the samples are falling under excellent to good water category and suitable for drinking water purpose.
