Usually, after someone asks "What is groundwater?", the next immediate question is "How do I find groundwater?" So today, we are teaching you the best way to find groundwater - Multi Electrode Electrical Resistivity Tomography Equipment to find groundwater. First, we must remember where we can find groundwater. As you know in our groundwater education series, the aquifer is a natural underground reservoir that can be used as a source of water.

There are few geological formations in the ground that can occur in aquifers.The area where groundwater can occur must be porous. The sand and gravel beds are porous and can contain water. The hard rock rupture zone is porous and may also contain water. Aquifers or rock layers containing water can be of any size, even small aquifers are valuable for farms or small villages.

The color scale shows the resistivity of the ground. The resistivity of the crack will be lower than the resistivity of the hard rock, because in hard rock, moisture will accumulate in the crack of the crack zone - the blue color in the crack is lower than the green color in the hard rock around the crack. So why is the resistivity there lowered? Because it contains moisture, and it is more conductive than hard rock.
