The current study includes applying 2D Azimuthal resistivity imaging using Wenner configuration in the area which located in Babylon, between longitudes (44 ˚25' 2"- 44 ˚25' 5.3") and latitudes (32 ˚27' 12.8"- 32 ˚27' 15.5"). ABEM Terrameter LS used for data collection. The survey design based on choosing the electrode configuration taking into account available information about the site and the advantages of the ERI technique. 2D electrical resistivity imaging sections have been obtained. The data analysis comprises of 2D inversions using the RES2DINV software. The measurements conducted with total length 80 meters to give the possibility depth to study surface changes in values of resistivity and to determine the direction of subsurface flow for contaminated water along 4 tracks at 45°.It was noted that the major quantitative of contaminated water moving toward the south-west, while it is found that there isn’t any movement in other direction .It is found that 2D Azimuthal resistivity imaging is an effective tool for detecting the movement direction of groundwater contamination.
