The Benin Formation beneath the Niger Delta coastal region is characterized by an abundance of groundwater resources. The salinization and proximity of aquifers to the seashore hinder the availability of freshwater in the coastal regions. The groundwater in most estuary environments, where continental groundwater mixes with saltwater from the sea are under serious threat from intrusion. The threat may emanate from geogenic factors and overstressing of coastal aquifers (Abam 2001; Post 2005). As a result, coastal aquifers are frequently contaminated by saltwater and the attendant effect is groundwater quality degradations (Batayneh 2006) and also, reduction in freshwater quantity. The salinization of coastal aquifers in the Niger Delta has been a cause of concern, but decision-makers and groundwater resource managers have not taken it seriously. Boreholes in these regions are frequently abandoned few months after drilling, owing to seawater intrusion (Ohwoghere-Asuma et al. 2017) and lack of proper geophysical investigation.
