Water catchment research has been done in Karang Anyar of Tarakan City with the aim to estimate the potential of groundwater aquifers. Groundwater is more widely used to meet the needs because of its better quality compared to surface water. The groundwater distribution is not only described vertically, to find horizontally can be seen through the deployment of geological formations that act as aquifers. Vertical Electrical Sounding method is one method that can be used to predict geological and hydrogeological conditions. Based on geoelectric exploration using a resistivity meter based on boost converter shows the presence of groundwater in a depth of 7. 91-_44. 33 meters with resistance of 27. 22 Ωm and the estimated lithology is sand. According the research could determine that resources ground water in Karang Anyar village is prospectly.

This paper presents aquifer transmissivity values obtained from vertical electrical sounding method from some locations in Port Harcourt Local Government Area of Rivers State. Twelve (12) stations were occupied using the Schlumberger electrode configuration with maximum electrode spacing of 400 m. The data were interpreted using IPI2WIN software version 3.0.1 (2003).The results reveal four layer strata with transmissivity (Tr) values of between 145.53 and 18264.42 m2/day with average value of 7252.23 m2/day. These indicate high aquifer transmissivity values for the study area with high permeable and significant storability of the formations that enhances the migration and circulation of ground water within the region. The results indicate that the southern part of the study area is the most prolific in terms of groundwater exploitation and thus the most promising in sitting productive boreholes.
