Review of passive groundwater remediation systems: Lessons learned Oak Ridge Y-12 Plant, Oak Ridge, Tennessee

摘要

One of the proposed solutions for treatment of the contaminated groundwater in the Bear Creek Valley is the installation of a passive treatment system. Such a system would use a reactive media installed in a continuous trench or in a gate as part of a barrier wall and gate system. This report evaluates information on five similar systems (no information was available on two additional systems) and evaluates the shortcomings and the advantages of each. Section 5 provides a short summary of the findings and presents some recommendations on how to avoid some of the common problems encountered with the existing systems.
