Geophysical investigation was carried out around the University Health Sciences of the Osun State University, Osogbo using the Schlumberger technique of the electrical resistivity method. The aim of the study was to evaluate the groundwater potential and to access how protected the aquifer in the area could be to surface pollutants. Four (4) vertical electric sounding (VES) data were acquired.

Geophysical methods are used to identify seawater intrusion based on resistivity values. Resistivity values are indirectly proportional to the conductivity of the groundwater. Usually, groundwater will have high resistivity values. But in coastal regions, low resistivity values are observed, indicating the presence of seawater.

Early Methods Of Groundwater Exploration To best understand how electrical resistivity surveys for groundwater exploration work today, it’s important to understand where resistivity testing began. Brothers Conrad and Marcel Schlumberger performed the very first investigation of how electrical current moves through the ground and what you can detect using an electrical resistivity . Electrical resistivity survey were carried out at Jubilee Homes Parkland, to delineate subsurface layers and determine the ground water potential, so as to make adequate provision of portable water supply for the settlements springing up within this area.

The Further Development of Electrical Resistivity Techniques for Determining Groundwater Quality. Author: Finch, J. Electrical methods are particularly suitable for groundwater studies because hydrogeologic properties, such as porosity and permeability, can be correlated to electrical resistivity values.
Geo-electrical techniques are essentially concerned with the measurement of electrical resistivities of subsurface materials, which preferentially provides information on the different geological layers, structures and the associated occurrence of groundwater Cited by: Application of Geological and Electrical Resistivity Methods for Groundwater Studies at Tatiko, North Central Nigeria Article (PDF Available) in Global Journal of Geological Sciences The main objective of this study is to identify the shallow aquifer and salt/fresh water zone distribution in the study area using geophysical technique represented by electrical resistivity method.
As, the electrical resistivity method is considered as one of the most powerful techniques in the groundwater exploration (Zohdy,Telford et Cited by: 4. The electrical sounding provides information about vertical changes in subsurface electrical properties and thus, it is useful in the determination of hydrogeologic conditions such as the depth to water table, depth to bedrock, and thickness of soil (Zohdy, ).
The electrical resistivity imaging maps ground water contaminant leachate plumes. Electrical resistivity and induced polarization surveys have been conducted for groundwater exploration at granitic formation.
This study discusses the earth materials resistivity. Identification of damages/changes that are affecting the underground water quality due to the effect of anthropogenic activities is often done after environmental problems have become evident or water portability being strongly affected.
Two main applications of electrical resistivity tomography (ERT) methods have been addressed covering characterization of leachate movement from a. progress in applying electrical methods to ground-water exploration began during World War II.
French, Russian,and German geophysicists are mainly responsible for the development of the theory and practice of di re¤t electrical prospecting methods. Definition and Units of Resistivity. ELECTROMAGNETIC METHODS Introduction: Electromagnetic induction (EM), as the name implies, uses the principle of induction to measure the electrical conductivity of the subsurface.
Unlike conventional resistivity techniques, no ground contact is required. This eliminates direct electrical coupling problems and allows much more rapid data. The objectives of this study were to (1) explore the characteristics of the electrical resistivity (ρ) and soil water content (θ) under different site conditions in the CLP, (2) evaluate the effects of land use, soil texture, soil depth, and dry and wet soil conditions on the relationship between the electrical resistivity.
The aim of this study is to determine groundwater level at slope areas using electrical resistivity method and to verify groundwater level of the study area with standpipe piezometer data.
Electrical resistivity survey in the field The resistivity survey was done in this research to study groundwater potential in Lower Ponnaiyar sub-basin, such as depth, thickness, resistivity and sediment at which water can be obtained.
The geoelectrical methods used in the survey are VES and with the aim of determining the sub-surface. Groundwater Exploration using 1D and 2D Electrical Resistivity Methods Jonas N.

investigations for many years in improving the instruments and development for better result in widening its applications. Electrical Resistivity Method (ERM) is part of geophysical methods which used as preliminary step involve in any groundwater exploration.
ERM has been applied for many years. Integration of VLF-EM and electrical resistivity sounding results enabled identification of good site for productive borehole and groundwater in a typical crystalline terrain as the studied area. The Groundwater potential map produced shows a reliable agreement with the groundwater discharge from existing boreholes within the study area.
Electrical Resistivity Fundamentals Advantages Limitations obtained from a geophysical investigation can be used to determine the subsurface conditions at, and in the vicinity of, a site. The use of geophysical methods at hazardous waste and ground water pollution sites is a fairly recent development.
In the past. Electrical resistivity survey, down-hole logging and pumping test were carried out in Delta Central District of Nigeria to determine the groundwater potential and aquifer characteristics of the.
Electrical resistivity methods are frequently used as investigation tool in groundwater exploration to obtain, details about the location, depth and apparent resistivity of the subsurface layers. Francois Fourie currently works at the Institute for Groundwater Studies (IGS), University of the Free State.
Francois does research in Hydrogeology and Hydrogeophysics. Electrical resistivity tomography (ERT), an advanced non-invasive technique, can effectively and economically be used to delineate and predict the contaminated zoned of groundwater.
This study developed a correlation with which the quality of groundwater near a non-engineered landfill can be known without making any borehole and laboratory.type, nature & number of aquifers, the quality of ground water.
