The primary objective of this study is to evaluate the suitability of water resources, for various purposes in the Dujaila River, Wasit Governorate-central Iraq. Physical and chemical properties have been investigated for 9 surface samples of the period August 2015- March 2016. The tests have been taken for the water major ions, total dissolved solids, electrical conductivity and acidity .
