Geoelectric Sounding for Identification of Aquifer Layer in East Turatea Village South Sulawesi Province

Abstract

East Turatea Village farmers still depend on rainwater for irrigating their rice fields. This study aims to identify groundwater aquifers in the village of East Turatea which can be used as water sources in irrigating rice fields. The method used is the correlation of well data and Vertical Electric Sounding (VES). Well data is result of water table mapping at three measuring stations. Measure the resistivity of rock using a resistivity meter with a length of 200 m with two Vertical Electric Sounding (VES) points. The measurement results are then processed using Progress software to produce a Vertical Electric Sounding (VES) with a resistivity variation to depth. The result this study found that East Turatea Village’s groundwater system in the form of shallow groundwater aquifer has a resistivity value of 0.84-5.5 Ohm.m at a depth of 6.04-31.88 m. Meanwhile, deep groundwater aquifers are at a depth of more than 53.8 m with a resistivity value of 1.94 - 2.75 Ohm.m. East Turatea Village groundwater aquifer is estimated to consist of permeable layer such as sand which is in a saturated zone.
