“…The value of transmissivity of this study ranges from 0.2694 to 1.9826 m 2 /day, with an average value of 0.8514 m 2 /day see Table 2. Transmissivity is the ability of an aquifer to convey groundwater throughout its entire saturated thickness (Opara, et al, 2022). Transmissivity is the maximum groundwater flow rate possible through a stretch of an aquifer with a unit width and a unit hydraulic gradient.…”

Geophysical investigation involving groundwater flow modeling was carried out in Orekepe, Delta state to determine the parameters that guarantee groundwater quality. The study entailed the carrying out of twenty-five (25) vertical electrical sounding (VES) using Schlumberger configuration with a maximum current electrode separation of 250 m. VES sounding within the study area was used to calculate transmissivity (T) and hydraulic conductivity (H). Groundwater Vista Version 3 groundwater modeling software was used to calculate the mass balance summary, section raw, and groundwater flow direction using the values of the aquifer parameters that were determined in this investigation. According to resistivity sounding results, the investigation encountered layers that ranged in number from three to four different layers. Further derivation from T and H led to the conclusions that the corresponding values were 0.2694 to 1.9826 m2/day and 0.037 to 0.042 m/day. According to groundwater modeling findings, groundwater moves along the SW to NE axis of the research region with a about 0.002 gradient toward the NE. Based on the direction of groundwater flow, the water-bearing units may be prone to contaminants. It, therefore, recommended that constant monitoring and management of groundwater using several scientific methods should be carried out from time to time.

“…Geo-electric techniques have gained significant status as a veritable tool in providing solutions to diverse problems across several fields such as geotechnical, geological, and subsurface environmental studies (Akakuru et al, 2023a, b;Nyaberi, 2022;Opara et al, 2023;Ekwe et al, 2018). Guma et al (2015) and Ekwe et al, (2018), among other numerous authors, have demonstrated the efficient applicability of this method in describing aquifer parameters, aquifer protective capacity, moisture content, etc.…”

The study investigates the electro-geophsysical method's application to assess corrosivity, competence, and aquifer vulnerability in Njaba and its environs, in southeastern Nigeria, aiming to determine soil suitability for engineering constructions and estimate aquifer vulnerability. Urbanization in the area has led to increased man-made structures and surface pollution exposure. Twenty-three geo-electric resistivity soundings were conducted using ABEM Terameter SAS-4000 and Schlumberger configuration with a maximum half-current electrode spacing of 500 m. Results indicate undulating topography with elevations ranging from 361 to 1336.9ft. Soil resistivity assessment reveals 43.5% moderate competence, 26.1% competent, and 26.1% highly competent zones, with the remainder exhibiting incompetent clay lithology. Corrosivity assessment shows 73.9% essentially non-corrosive and 26.1% mildly corrosive topsoil. The study identifies a semi-deep aquifer system with depths ranging from 79.2 to 115 m and thickness from 23.4 to 48.5 m. Aquifer resistivity ranges from 28700 to 990 Ωm, indicating clean sand to sand with clay admixtures. Hydraulic conductivity varies from 0.0852 to 27.90068 m/day, suggesting clean sand. Aquifer vulnerability assessment indicates a high to moderately low protective capacity, making most of the area suitable for engineering construction and groundwater development. The study highlights the reliability of geological and geo-electric methods in delineating hydraulic conductivity and lithostratigraphic units. It recommends corrosion-resistant pipes in mildly corrosive areas to prevent pipe rupture within a depth of approximately 1.1 m.

“…On the other hand, electrical surveys help to determine the distribution of resistivity values inside the subsurface by capturing samples from the earth's surface (Eyankware and Aleke, 2021). These surveys have been used for years in hydrogeological, mining, geotechnical, and environmental investigations (Opara, et al, 2022). Following that, the true resistivity values are estimated using the obtained data (Oli, et al, 2021).…”

Granitic Gneiss and Banded Gneiss make up the bulk of the local rock types, and quartz veins are the most common intrusions seen there. Tectonic upheavals in the earth's crust are responsible for the region's structural features, including as foliations, folds, joints, and fissures. The goal of this research is to integrate several scientific techniques to subsurface structure definition. For this study, 16 Vertical Electrical Sounding (VES), petrophysical study, and background knowledge of geology were used to delineate subsurface rock. The Schlumberger array with a maximum electrode separation of 300m was employed for VES. Elete's true aquifer resistivity map shows that the South-Eastern and North-Eastern axis has relatively low resistivity values, which may indicate the presence of an aquiferous zone, while the North-Central and Southern regions have a wider range of resistivity values, which may not be consistent with a water-bearing zone. Additionally, petrographic analysis of the rock reveals that the mineral composition of Granitic Gneiss is Quartz (41.72%), Plagioclase (10.79%), Biotite (25.17%), Muscovite (19.42%), and Opaque (2.87%). While biotite makes up the granite gneiss. Biotite (45%), Muscovite (9.93%), Quartz (36.87%), Plagioclase (4.26%), and Opaque (3. 55%).Hydrogeologically, it stands to reason that Elete and its surroundings are situated in a region with medium to good groundwater potential based on the information at hand and the results of the geophysical investigation. Weathered/fractured basements are anticipated to contain productive aquifers.
