تThe pumping test and recovery data of the three wells Al-Ourba, Al-Qadiseya and Hettin distributed in the Al- Shimal District, north of Iraq. were analyzed using Hantush method, Walton method and Theis Recovery method to derive the hydraulic parameters such as transmissivity (T) and hydraulic conductivity (K) of the water bearing formations. The results of analyzed data show that the average transmissivity (10, 4.7 and 7.8) m2/ day, of wells Al-Ourba, Al-Qadiseya and Hettin respectively, and the average hydraulic conductivity (0.17, 0.12 and 0.20) m/day of these well respectively. The results of pumping test also show that water table return to static condition during (30-40) minute after (600) minute of pumping of each well.
