Abstract: The present study is an attempt to assessment the groundwater quality of Gleewkhan village southeastern of Mosul city, for irrigation and livestock drinking by using WQI. Forty eight water samples were collected to determine their physical and chemical properties by using standard laboratory methods. From the analyzed data, some parameters like MAR, P.S and RSC have been calculated to identify the irrigational suitability, WQI model was applied for evaluation the groundwater for agricultural uses according to universal standard classification. It has been found that some of the measured parameters were high, especially, Ec25, P.S, MAR, Ca, Mg, Cl and SO4 ions which reached to 4652 μS.cm–1, (23.8,62, 22.4, 19.6, 17.6 and 23.8) meq. l–1 respectively, so, it was affected on water quality and would be considered as a very high salinity (C4) according to USSL. Interestingly, the MAR, Cl, HCO3 show that % 88 of the water samples are suitable for irrigation practices with some problems appear due to high values of P. salinity. Also, the results analysis of (WQI) confirm that, the groundwater in the study area ranged between class I (Excellent) to class II (Very good) categories for livestock drinking and class II (Very good) to class III (Marginal) categories for irrigation purpose. So, these groundwater should be used only with the soil having high permeability with some constraints imposed on types of plant for specified tolerance of salts.
