Groundwater impacted by chemicals of concern is the largest liability in the Defense Environmental Restoration Program. SERDP and ESTCP have funded research projects to develop more quantitative assessments of contaminant plumes in groundwater to support transition from active to more passive remedial strategies. This session highlighted approaches, methods, models, and tools that these projects have developed.
