Triad Issue Paper: Using Geophysical Tools to Develop the Conceptual Site Model

This technology bulletin explains how hazardous-waste site professionals can use geophysical tools to provide information about subsurface conditions to create a more representative conceptual site model (CSM). The CSM is a tool for gaining a synergistic understanding of the site, improve cost effectiveness, and improve decision-making within the Triad approach. Geophysical tools can be applied to create more robust CSMs with more complete data sets that result in a more representative and accurate depiction of the site characteristics at Brownfields and other hazardous waste sites.
