The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface conditions. Both two dimensional (2D) and three dimensional (3D) resistivity imaging were conducted for the site. A geotechnical site investigations program, which included three test soil borings, was conducted, to confirm the finding from resistivity imaging. Keywords: geo-hazard; RI; resistivity imaging; site investigations; geophysics; environmental technology.
