The current study application water quality index to study the groundwater used for irrigation in some parks in the city of Mosul. Six regions were selected from the city of Mosul to study A period of five months from the year 2023. The water quality index was calculated based on eleven standards (pH, electrical conductivity, Chloride ion, and Bicarbonate ions, as well as the seven irrigation indicators, which are Sodium Adsorption Tate, Sodium Percentage, Potential Salinity, Residual Sodium Carbonate, Kelly ratio, Permeability index and, Magnesium Adsorption Ratio). The results of the study indicated that the values of pH and electrical conductivity ranged between (7.498-6.860) (1122-2068) microsiemens/cm, respectively, and values of sodium adsorption rates and the percentage of sodium ranged between (0.708-0.335) meq/l (10.081-4.699) respectively, Potential salinity values reached (6.671) meq/l, while the study did not record any value for the residual sodium carbonate and recorded the highest value for the Kelly ratio around (0.133). according to irrigation indicators The results showed that groundwater is suitable for irrigation. While the results of the water quality index study showed that the values ranged between (12-8.79), which is considered an excellent water for irrigation, according to the values of the water quality coefficient.
