Geophysical investigation of groundwater
Groundwater is one of the most demanded earth resources which is used by man for daily activities. Investigation of groundwater water involves the use of geophysical methods which ranges in types, one of the common used method is the Electrical Resistivity method of groundwater investigation. Electrical Resistivity method is easier, faster, cheap and reliable. Different field approach are further used which may include the Horizontal Profiling and the Vertical Electrical Sounding for depth determination. They measure both the lateral and vertical extent of an area. Different arrays are further employ which may include the commonly know array, the Schlumberger and the wenner array. Since water is a good conductor of heat and electricity then the Resistivity will be said to be low while the conductivity will be high alongside but reverse is the case for oil. An area will low Resistivity will be further probe and a well will be bore into the earth surface. After then harvesting if the groundwater could follow if the water is therefore safe for daily activities.
