The study gives an overview on the utility of two dimensional direct current resistivity methods to explore the subsurface condition of Dutse Model International School and its Environs. Four parallel profiles each of length 200m and separated 120m apart were established. Currents and corresponding voltages were collected for the various investigating points with electrode spacing ranging from 5 to 60m. The collected data was reduced to resistivity values and then arranged in Notepad in a format acceptable to the software used in generating the resistivity sections for each profile. The resistivity sections were transformed into geologic section based on the geology, borehole data of the area and standard resistivity values of earth materials. The resistivity as well as the geologic section was used to draw inferences with regards to stratification and its groundwater potentials of the area. The study identified that the second profile with end point latitude 11°45 ́46.33 ́ ́N to 11°45 ́42.09 ́ ́N and longitude 9°23 ́50.66 ́ ́E to 9°23 ́55.62 ́ ́E has the best fractured basement coverage layer and favorable resistivity value of 600Ωm to 900Ωm. Consequently, the profile was recommended for groundwater exploration activity and was selected to provide a sustainable yield to even motorable borehole. The recommended depth of exploration for groundwater exploration was from 60m to 70m.
