Depth estimation of the aquifer layer using the geoelectric resistivity method
Abstract
At present, the distribution of water received by the ITK campus only comes from the PDAM and often experiences interference. Based on this case, a solution is needed to overcome the limitations of water by finding a layer of aquifers around campus area of ITK. The purpose of this study was to estimate the depth of aquifer and subsurface stratigraphy around ITK using the geoelectric resistivity method with schlumberger configuration. The resistivity geoelectric method is used to determine the subsurface structure based on the distribution of rock resistivity values. The results of the interpretation indicate that the subsurface statigraphy of the study area consists of top soil with resistivity 36.9 Ωm - 558 Ωm, sandy clay with resistivity 16.1 Ωm - 64.9 Ωm coal insertion with resistivity 637 Ωm clayey sand with resistivity 133 Ωm - 174 Ωm, and clay with a resistivity of 2.32 Ωm - 8.27 Ωm. The coal and clay seams are aquiklud, the sandy clay layer is aquitar, and the layer that includes aquifers is clay sand layer. The depth of the aquifer at each measurement point on average has a range from a depth of 56.5 m - 72.8 m is medium to productive aquifer
