Identification of Aquifer Potential by Geoelectric Method in Gedangsari District, Gunungkidul Regency

Abstract

Water is a very important natural resource that is needed by all living things in all their life activities. Research related to water and how to use water resources is an important issue. The amount of fresh water available on earth is only about 25% of the total water. The aim of this study is to identify potential aquifers with the geoelectric method. This can be a consideration in determining the right location of the well in relation to efforts to obtain potential groundwater resources to meet the needs of raw water, both in terms of quantity and quality. The method used is a field survey by making observations including rock permeability measurements, infiltration, laboratory and studio work. Field work also includes geoelectric measurements, observations of groundwater levels and land use, and analysis of aquifers to determine the location of drill points that have the potential to be developed. The results show that the supply of raw water for a number of locations spread across Gunungkidul Regency is very much needed, considering that in the dry season there is a shortage of water. Groundwater conditions using the Schlumberger Method show that they have sufficient raw water potential, but in terms of depth and discharge, each location is different from one another. Planning for borehole construction is highly recommended, and planning is adjusted to the amount of demand and availability of raw water.
