Title: Advanced Self-Potential Inversion. Development and Use for Investigating Natural Recharge Processes at the ORNL IFC

Understanding the influence of coupled biological, chemical, and hydrological processes on subsurface contaminant behavior at multiple scales is a prerequisite for developing effective remedial approaches, whether they are active remediation or natural attenuation strategies. To develop this understanding, methods are needed that can measure critical components of the natural system in real time. The self-potential method corresponds to the passive measurement of the distribution of the electrical potential at the surface of the Earth or in boreholes. This method is very complemetary to other geophysical methods like DC resistivity and induced polarization. In this report, we summarize of research efforts to advance the theory of low-frequency geoelectrical methods and their applications to the contaminant plumes in the vicinity of the former S-3 settling basins at Oak Ridge, TN.
