THE INVESTIGATION OF GROUNDWATER POTENTIAL BY VERTICAL ELECTRICAL SOUNDING (VES) APPROACH IN ARGUNI BAY REGION, KAIMANA REGENCY, WEST PAPUA
Abstract
This research was conducted within some villages in the surrounding area that administratively including
Arguni Bay District, Kaimana Regency, West Papua. The main objective of this study is to vertically measure
resistivity value of aquifer with the intention of recognizing deep groundwater potency as a source of native’s domestic
needs. In addition, VES method by Schlumberger electrode array was applied within 18 locations, which expectantly
represent the whole area of research. The resistivity data is then interpreted by IP2Win 2.1 Geoelectric Software to
entirely describe the aquifer system as well as the occurrence of groundwater. The result indicates that vertically, the
aquifer system is dominated by interbedded of claystone and sandstone (argillite group) as a past marine environment
mineral. In addition, geomorphological and resistivity sounding interpretation gives a viewpoint that the landforms of
the research area may be typified as Structural Mountain with the slope direction is towards the island beaches. Also,
structurally, the main groundwater system is fractured aquifer with very limited productivity of groundwater resources.
As consequences, this aquifer is more to be an aquitard, rather than an aquifer.
