Assessment of water quality characteristics and calculation of coefficient (WQI) for some water sources in Abu-Maria village Tal-Afar district / Nineveh province

The present study investigates the suitability of some water resources of Abu Maria village in the district of Tall Afar for human uses. Two springs and eight dug deep wells were chosen to conduct some quality tests such as pH, dissolved solids, total hardness and the concentration of cations and anions, Water quality for drinking were assessed by determination of water quality index (WQI), as well as their suitability for domestic uses according to Kamensky classification . The result revealed that water resources under study have high concentration of TDS,T.H and SO4 = which amount to 2003, 2020, 2136 mg . l-1 respectively, thus WQI is above standard, so it isn't suitable for drinking ( category V), in spite of low WQI results which are ranged between 1.55-6.76, it is also unsuitable for domestic usese because of high concentration of calcium and sulfate .
