A scientific divining rod for measuring electrical conductivity as an indicator of underground water supplies is being developed at Macquarie University, Sydney, Australia. Keeva Vozoff, geophysicist in charge of the project, said: ‘Conductivity rises considerably where there is water. We will be able to locate water nearest the surface and determine where it lies in large volumes for towns and factories. The method is based on solid physics instead of the ancient divining rod method. It is an extension of the work on deeper targets such as petroleum exploration.’
