Ground Water (GW) Department
Groundwater is water located beneath the earth’s surface in the soil pore spaces and in the fractures of rock formations. An aquifer is a layer of porous substrate that contains and transmits groundwater. Where water can flow directly between the surface and the saturated zone of an aquifer. Groundwater is naturally replenished by surface water from precipitation, streams, and rivers.
Ground Water Investigation / Exploration
The principle of this method is to insert a electric current, of known intensity, through the ground with the help of two electrodes (power electrodes – AB) and measuring the electric potential difference with another two electrodes (measuring electrodes – MN). The investigation depth is proportional with the distance between the power electrodes.
