    Groundwater identification in Gean De Green Housing, Rimba Panjang Village, has been carried out using geochemical and geoelectric methods of the Wenner- Schlumberger configuration. This study aims to identify aquifer layers, determine flow patterns and test the quality of groundwater. Measurements were made on two tracks with a length of 115 meters for each track. Based on the results of data processing, it is known that the groundwater aquifer is at a depth of up to 9,26 meters below the surface with a resistivity value (6,92 – 48,3) Ωm. It spreads from North to South and from East to West with a thickness of 8,01 meters. The lithology of the subsurface layers in the study area is a layer of sand and gravel, dry gravel, and sandstone. Testing the quality of groundwater in terms of pH parameters obtained an average value of 4,3 and iron metal content of 0,1774 mg/L. Overall, the results of the water quality test in the area of this study are not suitable for consumption because it is too acidic, but still safe and suitable for other purposes
