Why Focus on the Geology? by Rick Cramer, AECOM

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, …

Effective and Sustainable Combined Remedies using Single Application of Multi-functional Ammendments

The combined remedy approach to groundwater remediation optimizes contaminated site cleanup as measured by technical efficacy and sustainability. Regardless of the potential for improving site cleanups, however, there are still obstacles limiting the implementation of combined remedies. These obstacles can often be circumvented by employing multicomponent and multifunctional remedial amendment formulations delivered with a single …
