The quality of water cannot be overlooked as it is an important element required by every being in existence. Water majorly is used as drinking water and if not properly looked after could lead to various health and environmental issues. Fluoride and arsenic are naturally occurring pollutants with their sources being traced to either anthropogenic or geogenic contributions. It is imperative to note that excessive consumption of fluoride and arsenic in water could result to serious health challenges. Elevated constituents of fluoride and arsenic in water have been reported in the northern and southern parts of Nigeria, but their concentrations are more prevalent in the north. The contaminants have been traced to some activities such as mining, improper disposal sites, agricultural practices, industrial effluents among others. Adsorption process has been suggested as the cost effective and environmentally friendly defluoridation, while nanofiltration membranes is the best removal process for arsenic in water.

Groundwater is crucial for the growth of any country. It is a vital resource for drinking water, agriculture, industry, and economic development. However, delineating the groundwater potential zones requires a systematic approach. This study assessed the groundwater potential zones (GWPZ) in the Ntabankulu municipality using remote sensing, geographic information systems, and analytical hierarchical process (AHP) techniques. Six groundwater controlling parameters were integrated to assess groundwater potential zones, including lithology, slope, lineaments density, land use/land cover, drainage density, and rainfall. The AHP pairwise comparison matrix was utilized to determine the normalized weight of the parameters. The parameters and their classes were assigned ranks, taking into account their influence on groundwater accumulation. The resultant GWPZ map was generated by integrating the parameters and their assigned weights in ArcGIS 10.8 software. The final map from the AHP technique showed five GWPZ, including very poor (13.06%), poor (25.36%), moderate (26.93%), good (22.72%), and very good (11.93%). Validation was done by using the existing 242 boreholes in the study area. Furthermore, the receiver operating characteristics (ROC) curve was plotted, and the area under the curve (AUC) analysis indicated a satisfactory accuracy prediction (AUC = 61%). The results of this study will assist in developing a proper plan for sustainable utilization of groundwater resources within the Ntabankulu municipality.

The world’s increasing demand for freshwater has put a strain on existing reserves in recent years, necessitating further exploration of new groundwater reserves. However, geologic provinces located within the contact boundary of Sedimentary Basin-Basement Complex region are somewhat faced with the problem of shallow sediment thickness. As a result, exploring for groundwater poses a challenge as the sediment thickness might be insufficient to host productive aquifers. Hence, exploring for faults and fractures zones that are embedded on the hard rock underneath the sediment is very essential and complimentary. In this study, high resolution aeromagnetic data over a litho-petrological contact zone of the Middle Benue Trough (MBT) and the Adamawa Massif were analyzed to delineate groundwater exploration areas using a simplified qualitative and quantitative approach. Visual inspection of isolated and aggregate anomalies is performed by analyzing their shapes, dimensions, lateral extents, and discontinuities. Lineaments were then extracted from the residual magnetic map to determine faults, fractures, and joints. A two-source-depth model is indicated by the Spectral Analysis technique used to determine the thickness of the sediments in the area. The deeper source (Z1) has a thickness of 0.9 - 3.6 km, while the shallow source (Z2) has a thickness of 0.1 - 0.8 km. While in some areas the overburden thickness may be sufficient for groundwater exploration, in others it was not, as indicated by the shallow magnetic depth, Z2. Nonetheless, areas of shallow thickness but with aggregates of faults, fractures, and joints were identified as possible locations for groundwater accumulation through magnetic lineament exploration.
