“…Adeyemo et al [ 30 ] recognized aquifer layer thickness as one of the three most important parameters after geology and aquifer layer resistivity. The thicker the aquifer layer, the larger the water column and hence the greater the potential for groundwater accumulation [ 22 , 30 , 36 ]. Aquifer layer thickness in the study area increases in a southward direction with the termitarium location and surroundings having greater thickness.…”

“…The VES field data acquired were interpreted using a 1D inversion iteration program, WinRESIST 1.0, through the following steps: Field data smoothing, removing electrical noises and matching the generated smoothed field data curves with standard auxiliary curves (e.g., [ 22 ]). Initial geoelectrical model preparation specifying number of layers, their thicknesses and corresponding resistivity and incorporating the geological and well information of the study area (e.g., [ 23 ]).…”

Termite nests have long been suggested to be good indicators of groundwater but only a few studies are available to demonstrate the relationship between the two. This study therefore aims at investigating the most favourable spots for locating groundwater structures on a small parcel of land with conspicuous termite activity. To achieve this, geophysical soundings using the renowned vertical electrical sounding (VES) technique was carried out on the gridded study area. A total of nine VESs with one at the foot of a termitarium were conducted. The VES results were interpreted and assessed via two different techniques: (1) physical evaluation as performed by drillers in the field and (2) integration of primary and secondary geoelectrical parameters in a geographic information system (GIS). The result of the physical evaluation indicated a clear case of subjectivity in the interpretation but was consistent with the choice of VES points 1 and 6 (termitarium location) as being the most prospective points to be considered for drilling. Similarly, the integration of the geoelectrical parameters led to the mapping of the most prospective groundwater portion of the study area with the termitarium chiefly in the center of the most suitable region. This shows that termitaria are valuable landscape features that can be employed as biomarkers in the search of groundwater.

“…Both the basement relief map and the basement resistivity map display a horst model with correspondence between depressions and low-resistivity zones (fracture basement) at the western part of the study area, which could be regarded as a groundwater discharge or collection zone. The groundwater recharge zone is located in the north and northeast (Adabanija et al 2015).…”

“…However, while several efforts have been and are being made to characterise the groundwater facies in an effort to ascertain and assess groundwater quality (e.g. Adabanija et al 2015;Olasehinde 2015;Machiwal et al 2018), little attention has been given to assessments of the vulnerability/susceptibility of geologic material as a medium to the contaminants that result from pollution of the groundwater (e.g. Rupert 2001;Babiker et al 2005;Akinwumiju and Olorunfemi 2017;Zuquette and Failache 2018).…”

The total longitudinal conductance S obtained from the interpretations of vertical electrical soundings data acquired near 40 well bores was calibrated using total dissolved solids (measured in situ) in the sampled wells' groundwater to determine the overburden protective capacity and groundwater corrosion in a crystalline basement complex of Ogbomoso North, southwestern Nigeria. The acidity (pH) and electrical conductivity (EC) were also measured. Groundwater corrosiveness was determined using the Langelier saturation index (LSI) and the aggressive index (AI). The computed S of predominantly H-, KH-, QH-, HA-and HKH-types resistivity curve was 0.037995-1.10878 mhos. The TDS, pH and EC of the water samples measured 36-747 ppm, 6.15-9.3 and 74-1491 μS/cm, respectively. The regression equation of the TDS-based S calibration curve indicates a strong positive correlation (R2 = 0.8932) and revealed the overburden protective capacity ranged from excellent to good, fair and poor. The computed LSI and AI were −3.61 to 1.2 and 7.8-12.8, respectively. The high values of both LSI (0.2-1.2) and AI (11.2-12.8) in the southwestern part suggest groundwater there is strongly corrosive, while low values of −3.6 to −1.2 and 7.8-10.2 in the northwestern and southeastern parts indicate non-corrosive groundwater.
