Subsurface geology defines the “plumbing” (permeable pathways) that largely controls the subsurface heterogeneity responsible for groundwater flow and contaminant migration at complex sites. A focus on the geology is imperative for understanding fluid migration in the subsurface. The 2013 National Research Council study regarding complex contaminated groundwater sites concluded that, due to inherent geologic complexities, restoration of these sites is likely not achievable. It is time for the environmental industry to focus on modern geologic methods to understand the subsurface. This presentation shows how existing data and established geologic analyses can move groundwater remediation projects forward through an improved, quantitative conceptual site model.

This presentation was originally given by Rick Cramer, Director of Science at AECOM, at a workshop presented by NGWA, US EPA, and REGENESIS®. We are excited to announce that a recording of this presentation is now available.
