A systematic and dedicated effort has been made to collect two-dimensional resistivity data of the subsurface formation of a sewage treatment site on Ahmadu Bello University main campus, Samaru, Zaria, Kaduna State of Nigeria, for research study. The Research site is located within the South-West region of the main campus, and part of the Kubanni Basin underlain by Precambrian rocks of the Nigerian basement complex. The main aim of the study is to use the 2D Wenner based configuration electrical resistivity tomography (ERT) technique to characterize the subsurface lithology of the site. The...
