“…The aquifer layer had a range of resistivity values that vary from 682 to 1347 Ωm, where the aquifer was found in the fissure and fracture of schist and sandstone rocks as revealed by Sukrisna (2004). High aquifer values are common in aged rocks such as schist and sandstone [21,39]. Apart from being a limited aquifer, schist can also act as an aquifuge layer, that is, a layer that cannot hold or drain water [28,40].…”

Increased anthropogenic activity in urban areas has exacerbated the vulnerability of groundwater resources. The AVI, GOD, SINTACS, and DRASTIC methods were used to analyze groundwater vulnerability in Pangkalpinang City. Schlumberger vertical electrical sounding was used to determine the lithology and aquifer configuration in the study area. There are three vulnerability index areas in the city of Pangkalpinang. Low levels of aquifer vulnerability were generally found in the southeastern and northwestern parts of the study area, whereas high levels of aquifer vulnerability were discovered in the northern and southern parts of the study area. Areas with low aquifer vulnerability levels generally have low hydraulic conductivity values on the protective layer. In these areas, groundwater extraction is possible with a reasonable extraction pattern. Industrial areas can also be built by considering environmental aspects. In an area with high-level aquifer vulnerability, groundwater pollution must be considerably managed. The areas should not be designated for industrial areas and excess groundwater extraction.

“…It is also widely used in research on aquifer susceptibility [20]. Vertical electrical sounding is a data collection technique widely used in geoelectrical research [21]. Schlumberger arrays are electrode configuration techniques in vertical electrical sounding that are widely used in hydrogeological investigations [22].…”

“…Electrical resistivity tomography allowed us to distinguish the distribution of electrical resistivity of the subsoil by relating the solid constituents of the soil, water tent, and temperature with respect to the electrical resistivity. This can be considered way to interpret the variability in the physical properties of the soil [10,14,15]. The res of this study are from a distance-depth stratigraphic section with a distribution of surface resistivity, which is easily understandable in geological terms, in which the e trical resistivity of the medium depends on the amount of water in the subsurface [16] determine the electrical resistivity of the structures, Equation (1) is used [17]: The methodology used was developed based on national and regional geological information [13] to determine the areas of hydrogeological interest in the Langos sector.…”

“…However, the complexity of studying groundwater due to the cost of traditional methods, such as drilling, means that there is a shortage of hydrogeological data in the country [8]. In this context, geophysical methods are a solution to this problem because they are widely used worldwide and provide acceptable results, which allow an understanding of the behavior of groundwater in the subsurface strata [9][10][11].…”
