Hydrochemistry and Water Quality for Alqosh- Kand Catchment Area North of Mosul / North of Iraq

Abstract

This study including evaluation of quality of groundwater of Alqosh area, through the physical and chemical analyses of (19) groundwater samples besides the information of one well is the well number (20) from (General Authority for Groundwater Commission/Nineveh branch) , and there is found the concentiration of Ca ++ is (57.25) ppm, Mg ++ (44) ppm, Na + (9.85) ppm, K + (0.67) ppm, Cl ̄ (12.15) ppm, SO 4-² (56.19) ppm, HCO 3 ̄ (295.45) ppm, NO 3 ̄ (3.74) ppm, pH (7.97) , E.C (657.95) µmohs/cm, TDS (596.9) ppm, TH (325.98) ppm, and there is found that the water of the study area is suitable for human consumption, except the well (3-5-15-16-18) is not suitable for human consumption, and there is found the quality of groundwater in the study area is bicarbonate, calcium and magnesium type, and the factor analysis is showed that there are three factors controlling the hydrochemistry of water in the area, the first and the second factor is natural factor represented by type of rock components of the studied area, and the third factor is anthropogenic factor which is human activities.
