Ground Water Survey Consultancy

We are into ground water survey consultancy .Ground water exploration is to assess the ground water potential in the unconfined aquifer, method of tapping ground water without any adverse effects, the rate and extent of salt water intrusion and then to suggest precautionary measures to prevent salt water intrusion. Electrical resistivity surveys were carried out in the field for locating the availability of water and its quality.

It is known as vertical electrical sounding (VES). The basis for making an electrical sounding, irrespective of the electrode array used is that the further away from the current source the measurement of the potential, or the potential difference of the electric field is made,

The Deeper the probing will be. It has been stated in many references on geophysical prospecting that the depth of probing depends on how far apart two current electrodes are placed. Furthermore, when sounding with a wenner or Schlumberger array, when the distance between the current electrodes are increased, the distance between the current and potential electrodes, at the centre of the array is also increased. It is this latter increase that actuallymatters.
In electrical sounding with the Wenne, Schlumberger arrays, the respective electrode spacing as AB/2 is increased at successive intervals and the value of the appropriate apparent resistivity.
