This review presents a detailed analysis of hydrogeological and hydrochemical conditions of the Niger Delta Basin. Hydrogeologically, the specific capacities recorded from different areas within this Basin vary from 6700 lit/hr/m to 13,500 lit/ hr/m. The water table is very close to the ground surface and varies from 0 to 4 meters. Unconfined groundwater aquifers occur in shallow unconfined aquifers, sands of the coastal beach ridges and river point bars, and sandy islands within the mangrove belt. There is a stable water table fluctuation which characterised the high precipitation zone. The shallow aquifers of Benin Formation are more porous than those in the Deltaic areas. In the southern areas, along the coastal zone, an artesian condition occurs. However, the aquifers are less transmissible with increased depth of the confined aquifer, owing to its more delicate texture. Therefore, more compact, and less permeable, or that there is not enough water in storage. More than half of groundwater sources in the Basin are acidic. Based on mean TDS concentration groundwater, fall in an excellent class for drinking. Groundwater classification based on conductivity showed all the reported findings indicate conductivity ranging from 250-750 μS/cm. Based on cation and anion chemistry, the Niger Delta Basin holds water of relatively acceptable drinking quality. However, the uncontrolled groundwater development, land-use changes, pollution from industrial, municipal, and agricultural effluents pose a threat to groundwater quality protection. Thus, a policy guideline is required to protect groundwater from pollution.

Water sources in volcanic areas are rather difficult to obtain. For this reason, a method is needed to determine the existence of a water source. One of them is the Geoelectric method. In this study, the obtained resistivity physical quantities are used to determine the position and calculate the aquifer potential. In this study, three groups of rocks were found, namely, the rock group with resistivity values of 174 Ω.m – 400 Ω.m, this group is thought to have no water, not suitable for drilling. The rock group by resistivity 115 Ω.m - 174 Ω.m, this group is suspected of having water but little, not suitable for drilling. Rock group by the resistivity of 115 Ω.m below, namely at position 115-155 this area is the position of the aquifer, suitable for drilling, in this area, it is suspected that there is an aquifer with an average depth monitored by the tool 16.5 - 42.5 m or a thickness of 26 m. The transmissivity value obtained was 15.47 (m2/day).

“…The 1D electrical resistivity technique has been applied in the Caldera of Lake Maninjau, West Sumatra to identify aquifer characteristics [10]. It has also been applied to explore groundwater aquifers and to design geological structures in the Dakhla area of Egypt [11], and to evaluate the potential of groundwater and the vulnerability of aquifers in Nigeria [12]. The first author has previously used this method to investigate the characteristics of groundwater aquifers in a critical land area of the Serayu watershed in Cilacap Regency [13].…”

A geoelectric survey using the 1D-electrical resistivity method was applied to design a groundwater aquifer model for the banks of the Serayu River in Sokawera Village, Somagede District, Banyumas Regency, Indonesia. The aim of this research was to identify the characteristics of aquifers in the research area based on resistivity log data. Acquisition, modeling, and interpretation of resistivity data were carried out and the results were lithological logs at seven sounding points. Correlation between the lithological logs resulted in a hydrostratigraphic model. This model is composed of several hydrological units, i.e. shallow aquifer, aquitard, and deep aquifer. The shallow aquifers are composed of sandy clay (10.81-18.21 Wm) and clayey sand (3.04-7.43 Wm) with a depth of groundwater from the water table to 27.51 m. The deep aquifers are composed of sandstone with variation of porosity (2.24-12.04 Wm) at a depth of more than 54.98 m. Based on this model, potential shallow aquifers were estimated to be at sounding points Sch-5, Sch-6, and Sch-7. This hydrostratigraphic model shows that the two types of aquifers are separated by an aquitard layer, allowing groundwater infiltration from the shallow aquifer to the deep aquifer and vice versa. Moreover, the Serayu riverbanks in this research area are estimated to be a groundwater discharge area.
