Overview of Effective Geophysical Methods Used in the Study of Environmental Pollutions by Waste Dumpsites

Abstract

The Application of various Geophysical Techniques for the assessment of the extent of environmental, groundwater and soil contamination by hazardous wastes have received the attention of a number of studies using various techniques some of which are ineffective. Consequently, this paper identified nine more effective Geophysical Methods used in the environmental and groundwater pollutions studies, which has been briefly discuss in relation to their general applications, data reduction requirement, basic principles, various advantages and limitations. The conclusion was that the successful use of any of this effective Geophysical Techniques depends on the careful design of the survey, site specification, use of combinations of technologies and combined data analysis techniques as a means to enhance the characterization effort. In addition, it is also dependent on the consideration of a number of key Geological and Cultural Factors (like; Nature of the Target, the Target Depth of Burial, Target size, Measurement Station Interval and Calibration of the Data) together with the Geophysical Data.
