Electrical Resistivity Tomography at the DOE Hanford Site [PDF]
Symposium on the Application of Geophysics to Engineering and Environmental Problems 1996, 1996 Recent work at the DOE Hanford site has established the potential of applying Electrical Resistivity Tomography (ERT) for early leak detection under hazardous waste storage facilities. Several studies have been concluded to test the capabilities and limitations of ERT for two different applications.

Cone-based electrical resistivity tomography [PDF]
Geophysics, 2006 Abstract Determining the 3D spatial distribution of subsurface properties is a challenging, but critical, part of managing the cleanup of contaminated sites. We have developed a minimally invasive technology that can provide information about the 3D distribution of electrical conductivity.

A convolutional neural network approach to electrical resistivity tomography
Journal of Applied Geophysics, 2020 Abstract Electrical resistivity tomography (ERT) is an ill-posed and non-linear inverse problem commonly solved through deterministic gradient-based methods. These algorithms guarantee fast convergence toward the final solution but hinder accurate uncertainty assessments. On the contrary, numerical Markov Chain Monte Carlo algorithms provide
