Short description: The complex structure of fractured-rock aquifers poses an enormous challenge for groundwater remediation professionals. The efficacy of geophysical methods at these sites is hindered by the lack of planning tools that assess their applicability given site specific conditions and objectives for clean-up. Synthetic modeling or "pre-modeling" represents a powerful approach to understanding the capabilities and limitations of geophysical methods to achieve different site clean-up objectives. Although synthetic modeling tools are available and widely used in research, applications in the environmental industry are uncommon. In this study, researchers (1) provide an overview of geophysical methods applied to characterizing and monitoring fractured-rock aquifers; (2) review case studies showcasing different geophysical methods; and (3) discuss best practices for choice of method based on synthetic modeling and decision support tools.
