One way to be able to identify rocks below the surface, depth, including groundwater aquifer layers is to do geophysical measurements using the schlumberger geoelectric method. This study aims to determine thickness and depth of aquifers in Lok Rawa Village, Mandastana District, Barito Kuala Regency. The results of the schlumberger configuration geoelectric study showed rock layers in Lok Rawa Village at the measurement points GL1, GL2 and GL3 consisting of weathered, sand, and fine clay (silt) layers. Lapiasan aquifers in Lok Rawa Village at the measurement points GL1, GL2 and GL3 consisting of free aquifer layers are estimated to occur at a depth of  3─5 m with a resistivity value of  7─15 Ωm. Depressed aquifer layer is estimated to be at a depth  of 25─75 m and  ≥ 110 m with resistivity values of  7─15 Ωm. Of the 2 types of aquifer layers, the most confined aquifer layer has the potential to contain ground water.
