Resistivity Surveys

Resistivity surveys are geophysical techniques used to measure the electrical resistance of soil and rock underground. By sending an electric current into the ground and measuring how much resistance it encounters, researchers can infer the presence of different materials, such as water, minerals, or pollutants. Areas with higher resistivity may indicate rock or dry soil, while lower resistivity often suggests water or clay. This method is commonly used in environmental studies, archaeological investigations, and resource exploration, helping to visualize subsurface conditions without the need for extensive digging.
