Groundwater exploration using 2D resistivity method in water supply for prevention of peatland fire at Kahayan Kuala area, Central Kalimantan

Abstract Resistivity data acquisition using the two-dimensional (2D) resistivity method has been carried out at 8 locations in Kahayan Kuala area, Pulang Pisau District, Central Kalimantan. The aim of study was to identify distribution type and depth aquifer layers other geological materials subsurface based on their characteristics. results showed that values northern part area ranging from 13.28–282 2.09–88.37 ohm-meter, while southern part, 0.32–25.75 ohm-meter. At range 41.77–88.37 67.7–187.79 ohm-meter are peat mud layers, 25.35–88.37 55.29–282.28 sandstone 2.09–34.31 13.28–67.78 were clay sandy layers. 5.97–25.75 4.46 - 25.75 0.32–5.97 Sandstone interpreted as confined aquifers, unconfined non-aquifer or sealing survey 10–40 meter 20–50 meter.
