AbstractAn electrical resistivity survey was carried out using the pole–pole configuration around the Sayanokami spring area in the northern part of Ito Campus (Kyushu University, Fukuoka, Japan) to study the groundwater aquifer and its electrical characteristics. A Code Division Multiple Transmission (CDMT) system was used. The CDMT system transmits 24 currents simultaneously and measures 24 potential responses with monitoring of actual current waveforms. The system can inject current from multiple electrodes into the underground environment simultaneously using different individual current waveforms. The two-dimensional (2-D) inversion results of the electrical resistivity data indicate three layers from top to bottom, as follows: (a) a thin layer with a thickness of 3 m and a low resistivity (< 50 Ω m) representing topsoil; (b) a groundwater aquifer layer with an average resistivity between 50 and 170 Ω m and with a thickness ranging from 7 to 10 m, and (c) a highly resistive bedrock layer with resistivities higher than 200 Ω m and occupying depths from 15 m to the base of the model.

Abstract An investigation has been made of the groundwater potentials of Orogun Town, Ughelli North Local Government Area of Delta State, Nigeria, using electrical resistivity survey. This study motivated to determine electrical resistivity parameters of the area. The aim of this work is to use electrical resistivity method to explore the groundwater potentials of Orogun Town with the determination of its Dar Zarrouk parameters. A total of eight vertical electrical sounding (VES) were conducted with maximum electrode spacing of 150 m. The data were acquired using ABEM SAS 4000 Terrameter and processed using IPI2win and Interpex softwares. The groundwater potentials of the area are evaluated based on the longitudinal conductance (S), transverse resistance (T), coefficient of electrical anisotropy (λ), resistivity for the formation ($$\rho_{\text{m}}$$ρm), reflection coefficient (RC) and resistivity contrast (FC). The results reveal four subsurface geoelectric layers in seven of the eight VES while one VES revealed three subsurface geoelectric layers. Resistivity values for all the layers in the study area are very high, higher than what is expected in a sedimentary basin as we have in the study area. The resistivity values range from 8470 Ωm (layer 1, VES 7) to 118,030,000 Ωm (layer 3, VES 8). Depth to aquifer in the study area ranged from 1.61 m (VES 2) to 12.41 m (VES 1), while resistivity values of the aquifer ranged from 64,182 Ωm (VES 3) to 118,030,000 Ωm (VES 8). The results from the formation parameters evaluated showed that the area has good groundwater potential but might have been highly contaminated, especially from hydrocarbon sources and other man-made pollutants. The suggested contamination of the aquifer is as a result of the high values of resistivity of the aquifer layers.

The ultimate aim of the electrical resistivity survey is to determine the resistivity distribution with depth on the basis of surface measurements of the apparent resistivity and to interpret it in terms of geology. Marble deposit was investigated with the application of electrical resistivity method using Vertical Electrical Sounding (VES) technique with the aim of characterising this deposit in parts of Okpella. Six (6) VES were acquired using the Schlumberger array for data acquisition with current electrode spacing varying from 1.0 to 150.0 m. The VES data obtained were interpreted using ipi2win Software. The results showed three layers indicating subsurface geologic sequence probed 26.4 m and beyond with clay/clayey sand (23.3 – 219.1 Ωm), sand (423 - 2040 Ωm) and marble (12661 - 404498 Ωm). The occurrence of marble deposit was revealed at VES points at 1, 2 and 5 in the studied area.  This study concluded that the study area had occurrence of the marble deposits, which would be of economic importance, if exploited.

Electrical Resistivity Method

Groundwater is water that occurs naturally in the subsurface, and is contained in the aquifer. Groundwater is the water source of the most widely used by the public for purposes of clean water. To determine the condition of the aquifer configuration one of the methods that can be used is the 2D electrical resistivity. Exploration drilling is one effective way to determine directly the presence of groundwater, but to determine the location of the drilling necessary geophysical approach to describe subsurface conditions prior to drilling. 2D electrical resistivity method is a geophysical method that utilizes dynamic electrical properties of the media path. 2D electrical resistivity measurements have been carried out in Kapuas, Central Kalimantan using Wenner configuration, the distance between the electrodes 10 meters, penetration depth reaches 80 meters, and and measuring some 21 track. Water potential zones were identified based on having resistivity range 15-25 ohm.m, contained in the sandstone layer, which is covered in a layer of impermeable mudstone layers. Location that has a high potential for groundwater recommended drilling done on the track P-07 and P-13, with an estimated depth of the aquifer between 25 meters and 30 meters. The highest groundwater potential lies between the drilling data PH-23 and PH-24, with the resistivity at that point reaches 300 ohm.m. Keywords : Groundwater, aquifer, sandstone, 2D electrical resistivity, resistivity, Kapuas

Groundwater is described as the water found beneath the surface of the earth in underground streams and aquifers and has become popular as a source of drinking potable water in Nigeria due to its quality when compared to other water sources. The Electrical resistivity method was employed in Imakun Omi Community, a coastal town in Ogun Waterside Local government area of  Ogun State with the aim of determining the groundwater potential of the area. A total of twenty (20) Vertical Electrical Soundings (VES) points were carried out in the area using the Schlumberger configuration with maximum current electrode separation (AB) of 300m using the ABEM SAS 1000 Terrameter. The results obtained were interpreted quantitatively and qualitatively using partial curve matching and computer iteration programs WINRESIST and SURFER 11 for the interpretation from which the reflection coefficient was computed. The groundwater potential of the rock units were evaluated and  40% of the stations show  high yield, 50% of the stations show medium yield and 10% of the stations was observed to have low yield. The aquifer thicknesses are very thick with values ranging from 6.9 m to 79.3 m, hence an average of 43.1mand overburden thicknesses ranging from 9.7m to 96.5 m, with an average of 53.1m
