Abstract
The interpretation of two resistivity curves over Iyakpi town within geologic terrain often referred to as
Ajali formation which bears false-bedded sandstone with associated clay and shale intervals in the
bottom section indicates that the area has an abundant groundwater potential. Existence of productive
borehole in the study area was field-confirmed. The study area is said to have a standing history of
abortive boreholes, resulting from failed drilling attempts. No dug well was sited in the community. The
study showed that the main lithologic units penetrated by the sounding curves are laterite, sandstone,
sandstone (dry with some clay/shale). This study revealed the possibility of having a maximum drill
depth to water table of 260 m (865.80 ft).
