The sixth subsurface layer consists of coarse grain sand and gravelly stones from 30 m to far depth with appreciable loose sand deposits beneath [13].
The aquifer performance is best at about
45 m. It is therefore recommended that boreholes for sustainable water supply in Edejekota boreholes should be
drilled to about 45 m to hit prolific aquifer. It is also recommended that other geophysical exploration methods such
as seismic refraction method may be employed to further investigate this area for economic purposes.
