Karakterisasi Zona Akuifer Menggunakan Metode Geolistrik Konfigurasi Wenner Dan Analisis Geokimia Di Kelurahan Sialang Sakti Kecamatan Tenayan Raya
Groundwater is a very important natural resource for human life, especially in areas with limited access to surface water. Identification and mapping of aquifer zones are important steps in ensuring the availability of quality and sustainable groundwater. This study aims to analyze the characteristics of aquifer zones in Sialang Sakti Village, Tenayan Raya Subdistrict, using the Wenner configuration geoelectric method and geochemical analysis to determine the potential of aquifers and groundwater quality in the area. The Wenner configuration resistivity geoelectrical method is used to detect the presence of aquifers based on the resistivity value of soil and rock on a 100-meter long track with a maximum depth of 15.9 meters. The data obtained was then processed using Res2Dinv software to produce two-dimensional (2D) modeling of the subsurface layer. Meanwhile, geochemical analysis was conducted by measuring pH, Total Dissolved Solid (TDS), conductivity, and turbidity parameters in ten water samples taken from residents' wells around the research site. The results showed that the main aquifer zone is located at a depth of 6.38 - 9.26 meters with a resistivity value of 1.01 - 1620 Ωm, which is thought to be a layer of sand and sandstone that has the potential to store significant amounts of groundwater. Groundwater quality analysis showed that most samples had a pH below the safe drinking water standard (
