Re-Inversion of Surface Electrical Resistivity Tomography Data from the Hanford Site B-Complex.

摘要

This report documents the three-dimensional (3D) inversion results of surface electrical resistivity tomography (ERT) data collected over the Hanford Site B-Complex. The data were collected to image the subsurface distribution of electrically conductive vadose zone contamination resulting from both planned releases of contamination into subsurface infiltration galleries (cribs, trenches, and tile fields) and unplanned releases from the B, BX, and BY tank farms and/or associated facilities. Electrically conductive contaminants are those that increase the ionic strength of pore fluids relative to native conditions. Most types of solutes released into the subsurface B-Complex were electrically conductive.
