Spatial Analysis of Qualitative Features of Groundwater for Human Uses: A Case Study of Ain Al-Hussan Villages, Sinjar District, Northwestern Iraq

The current study was conducted to determine the suitability of the water sources for human use in the villages of Ain al-Hussan affiliated with Sinjar District in Nineveh Governorate. Ten sampling sites were chosen, during the summer and autumn seasons, to conduct some qualitative tests such as pH, electrical conductivity, total hardness, and total number of bacteria, in addition to some positive and negative ions. The logarithmic model was also applied to determine the quality of water sources. The results indicated an increase in the concentration of sulfate ions and the total number of bacteria, which reached 1041 mg/L and 95056 cells. ml-1, respectively, exceeding the permissible limits for drinking and domestic uses, as confirmed by the results of the Water Quality Index (WQI), which ranged from (91.83 to 261.2), to classify the quality of the studied water as unfit for human consumption in its current state, as eighty percentof it was unfit for human consumption, and the rest was of very poor quality.
