Geophysical techniques have played a major role in subsurface investigation. These techniques include seismic, electrical, ground penetrating radar, gravity, electromagnetic, magnetic, etc. The problems that have been buffeting the geologist or geophysical researchers are in the wide coverage of any area of interest when investigating subsurface using these ground geophysical techniques. But the aeromagnetic technique has proven to be successful in this regard. Although the magnetic technique (aeromagnetic) has been applied successfully for mineral resources and hydrocarbon exploration, this study examins in detail the uniqueness of this technique (in terms of universality, acceptability and coverage) and its application to regional groundwater studies, especially where hydrogeophysical related equipment is not available. Furthermore, this aeromagnetic technique has been applied to determine the depth to magnetic source of Ado-Ota and environs in southwestern Nigeria. The result revealed that there are two geological environments in the study area, namely sedimentary and basement complex terrain which are very significant in groundwater studies. The shallow sources characterized the basement complex with depth ranges from 102.8 m to 246.1 m, and deep sources characterized sedimentary terrain from 710.0 m to 1,980 m.
