“…Results from these studies showed that HCO 3 ranged from 0 to 300.8 mg/l with an average value of 23.50 mg/l (Figure 11a). Bicarbonate is typically assumed to enter the groundwater system due to the uptake of CO 2 either from soil zone gases or direct atmospheric inputs [27][28][29][31][32][33]. Additional sources can come from carbonate dissolution.…”

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.

“…The hydrochemistry of Groundwater is the consequential of all the reactions and processes that operate in the water from right from the condensation in the atmosphere to the time is precipitated and collected by rivers and streams, recharged into aquifers and discharged by a well [15,[19][20][21][22]. Therefore, the critical insights about aquifers' geological history and its suitability for different uses can be revealed by the groundwater chemistry [15,[23][24][25][26][27][28][29][30][31][32][33].…”

“…The assessment of groundwater is an essential activity for rural and urban water management, particularly in semi-arid regions, [1][2][3][4] because the ionic composition of water has a significant influence on human health. [5][6][7] Using low-quality groundwater for drinking and irrigation affects human health and plant growth and contaminates soil, making it less suitable for agriculture and household uses. Shallow groundwater is the primary source of potable water and is commonly used for household and irrigation uses in rural Nigeria, 8,9 particularly in the semi-arid northern areas of Nigeria.…”

This study assessed shallow groundwater in rural Kebbi State using Pearson's Correlation (r), Factor Analysis (FA), and Hierarchical Cluster Analysis (HCA). One hundred (100) shallow groundwater samples were drawn randomly from hand-dug shallow wells in 10 Local Government Areas (LGAs). Physical parameters (pH, temperature, TDS, EC, salinity) were analysed in situ using hand-held metres. Separate water samples were taken to analyse ions (Fe, Zn, K, Mg, Mg, HCO 3 , Ca). Results revealed that shallow groundwater is lightly acidic, except in Zuru and Fakai LGAs, where an alkaline condition occurred. Correlation analysis revealed that the dissolved solids in shallow aquifers result from natural geological and anthropogenic influences. However, FA had shown that most of the variability in shallow groundwater is influenced by natural geological factors with little evidence from anthropogenic inputs. The HCA categorised shallow groundwater into three groups: those shallow wells having higher concentrations of Zn and Cl with more elevated salinity and temperature; those shallow wells having very low salinity in central Kebbi State, and those shallow aquifers having alkaline waters. Except for higher Fe and Zn concentrations, the shallow aquifers contained water of excellent quality for drinking. Correlation analysis, FA, and HCA present simple statistical tools for assessing the hydrochemistry of groundwater.
