As depicted in the figure on this page, the Office of Groundwater and Soil Remediation Program goals listed below include a number of interrelated action areas with associated objectives (listed further below by action area):
- Characterize and predict contaminant and system behavior (Action Areas 1, 2, 4, 5).
- Design/implement active remedial strategies to control contaminant flux (in situ) (Action Areas 2, 4, 5).
- Transition from active to passive remediation by understanding contaminant flux and monitored natural attenuation processes (Action Areas 1, 3, 5).
- Demonstrate long-term protection of environmental resources (Action Areas 1-5).
