“…Previous studies considered various materials such as sand, gravel, sand-gravel, clay, and clay-sand (Ahada and Suthar 2018 ). Others excluded the impact of the vadose zone entirely due to the non-availability of data in the assessment of the zone (Adnan et al 2018 ); since these materials have various resistivity values, the values of the resistivity of the zone were used in the classification of the zone (Bhatnagar et al 2022 ). Higher resistivity values were observed in the southern part of the state, including Ihiala, Ekwusigo, Aguata, Idemili North, and South LGAs.…”

This study evaluated the susceptibility to groundwater pollution using a modified DRASTIC model. A novel hybrid multi-criteria decision-making (MCDM) model integrating Interval Rough Numbers (IRN), Decision Making Trial and Evaluation Laboratory (DEMATEL), and Analytical Network Process (ANP) was used to investigate the interrelationships between critical hydrogeologic factors (and determine their relative weights) via a novel vulnerability index based on the DRASTIC model. The flexibility of GIS in handling spatial data was employed to delineate thematic map layers of the hydrogeologic factors and to improve the DRASTIC model. The hybrid MCDM model results show that net recharge (a key hydrogeologic factor) had the highest priority with a weight of 0.1986. In contrast, the topography factor had the least priority, with a weight of 0.0497. A case study validated the hybrid model using Anambra State, Nigeria. The resultant vulnerability map shows that 12.98% of the study area falls into a very high vulnerability class, 31.90% falls into a high vulnerability, 23.52% falls into the average vulnerability, 21.75% falls into a low vulnerability, and 9.85% falls into very low vulnerability classes, respectively. In addition, nitrate concentration was used to evaluate the degree of groundwater pollution. Based on observed nitrate concentration, the modified DRASTIC model was validated and compared to the traditional DRASTIC model; interestingly, the spatial model of the modified DRASTIC model performed better. This study is thus critical for environmental monitoring and implementing appropriate management interventions to protect groundwater resources against indiscriminate sources of pollution.

“…Using the Schlumberger configuration, which has 4 electrodes, consists of a set of current electrodes, called A-B or often called C1-C2 electrodes, and a set of potential electrodes, called M-N electrodes or P1-P2 electrodes [7]. The electrode and electric current are separated by a different amount [8].…”

One of Indonesia’s regencies known for its agricultural land is Sukoharjo. The shortage of irrigation water has caused many problems in past years. The purpose of the research was to better understand the subsurface structure to increase the effectiveness of drilling in deep groundwater. Schlumberger’s configuration with a deep aquifer irrigation target zone was used to conduct the investigation. The track’s length is between 275 and 300 meters. Information obtained about the depth of the aquifer zone in the southern part of Sukoharjo is estimated to range from 4.83 to 155.79 meters. In the southern part of Sukoharjo, most of the ground cover consists of layers of sediment, limestone, and sandy clay.

“…Geoelectrical methods are widely utilized for the exploration of groundwater resources, as the geoelectrical properties are related to groundwater properties, lithology, chemistry, and porosity [20][21][22][23]. The geoelectrical resistivity method is a cost-effective and easily accessible method for evaluating groundwater before investing in drilling [22,24]. The measured resistivity not only gives the presence of an aquifer but also gives information about groundwater quality [24][25][26].…”

This study aimed to investigate the potential reserves of potable water in Islamabad, Pakistan, considering the alarming depletion of water resources. A detailed vertical electrical sounding (VES) survey was conducted in two main localities: Bara Kahu (Area 1) and Aabpara to G-13 (Area 2), based on accessibility, time, and budget constraints. A total of 23 VES measurements were performed, with 13 in Area 1 and 10 in Area 2, reaching a maximum depth of 500 m. Geologs and pseudosections were generated to assess lithological variations, aquifer conditions, and resistivity trends with depth. Statistical distribution of resistivity (SDR), hydraulic parameters, true resistivity, macroanisotropy, aquifer depth and thickness, and linear regression (R2) curves were calculated for both areas, providing insights into the aquifer conditions. The results revealed that the study areas predominantly consisted of sandy lithology as the aquifer horizon, encompassing sandstone, sandy clay, and clayey sand formations. Area 2 exhibited a higher presence of clayey horizons, and aquifers were generally deeper compared to Area 1. The aquifer thickness ranged from 10 m to 200 m, with shallow depths ranging from 10 m to 60 m and deeper aquifers exceeding 200 m. Aquifers in Area 1 were mostly semi-confined, while those in Area 2 were predominantly unconfined and susceptible to recharge and potential contamination. The northwest–southeast side of Area 1 exhibited the highest probability for ground resource estimation, while in Area 2, the northeast–southwest side displayed a dominant probability. The study identified a probable shear zone in Area 2, indicating lithological differences between the northeast and southwest sides with a reverse sequence. Based on the findings, it is recommended that the shallow aquifers in Area 1 be considered the best potential reservoir for water supply. In contrast, deeper drilling is advised in Area 2 to ensure a long-lasting, high-quality water supply. These results provide valuable information for water resource management and facilitate sustainable water supply planning and decision making in Islamabad, Pakistan.
