A study in Idheze, Delta State used a method called Vertical Electrical Sounding to look at the layers of the ground and find where water can be found. They found that there are four or five layers in the ground, with the third or fourth layer holding water. The ground is made up of topsoil, clay, and different types of sand. They also discovered that all seven locations have good water flow, and boreholes can be built in any of them. Location 3 has the best water flow, while Location 6 has the least.
