Evaluation of Central Plateau Remediation Alternatives: Interim Status Report
- Pacific Northwest National Lab. (PNNL), Richland, WA (United States)
Several comingled groundwater contaminant plumes exist in the Hanford Central Plateau and are currently targeted by ongoing remedy efforts (i.e., pump-and-treat [P&T]). However, across much of the Central Plateau, the deep vadose zone is also expected to serve as a long-term source of contaminant flux to the groundwater. Contaminant transport in the groundwater and vadose zone often occurs at vastly different time scales. Remedial action is needed in the near term to address existing groundwater contamination, but for some waste sites, long-term vadose zone source control may be needed. The overall remediation strategy for the Central Plateau will require the development of remedial alternatives that consider the coupled groundwater and vadose zone system.
