“…This process is called barometric pumping and the well is called a barometric pumping well (BPW) [13,22,24,28]. When the BPW is not extremely deep, gravitational effect and vertical gas pressure difference inside the BPW can be neglected, and the gas pressure inside the BPW is uniform [22,24,28].…”

“…Passive SVE can either work as a stand-alone measure or in conjunction with active SVE [18]. It has been field tested as an effective soil remediation technology at several sites, including the US Department of Energy (DOE) Savannah River site in Aiken, South Carolina, and the Hanford site in Richland, Washington [13,22,24,28].…”

“…Case studies related to beneficial uses for environmental remediation, however, are more recent and were initiated by DOE laboratories (e.g., Pirkle et al, 1992;Rohay and Cameron, 1992;Rossabi et al, 1994;Rossabi, 1999;Riha et al, 1994) with field work primarily at the DOE Savannah River, Hanford, Idaho, and Nevada sites and by scientist studying bioventing for the DoD (e.g., Zachary, 1993;Zwick et al, 1994). These, and similar case studies, documented the performance potential and limitations for barometric pumping and provide a foundation for modeling and cost estimation.…”

an alternative project at the Savannah River Site designed to develop cost effective and environmentally protective technical solutions for the challenge of large and complex plumes of chlorinated volatile organic compounds (cVOCs) at DOE sites. The project builds upon the current U.S. Environmental Protection Agency (EPA) protocol and directive (EPA, 1998(EPA, , 1999 for monitored natural attenuation (MNA). The DOE effort focuses on three major technical thrust areas: mass balance, enhanced attenuation (EA), and innovations in characterization/monitoring. Each of these three topics is supported by a broad-based group of recognized technical experts and each group currently is developing an interim report related to the topic area. By introducing the concepts of mass balance and EA, along with the technical basis and documentation for these concepts, the project is working toward a goal of providing new and powerful tools for transitioning from active remediation to a protective long term monitoring state. This project is a departure from classical MNA in that its central theme is to take an active part, as needed, to achieve a favorable balance between the release of contaminants from sources (source loading) and processes that destroy or retard migration of contaminants in resultant plumes (attenuation capacity of the system). OBJECTIVESThe objective of this document is to explore the realm of enhancements to natural attenuation processes for cVOCs and review examples that have been proposed, modeled, and implemented. We will identify lessons learned from these case studies to confirm that enhancements are technically feasible and have the potential to achieve a favorable, costeffective contaminant mass balance. Furthermore, we hope to determine if opportunities for further improvement of the enhancements exist and suggest areas where new and innovative types of enhancements might be possible. TARGET AUDIENCEThe intended audience for this reference guide includes state and federal regulators, stakeholders, and environmental managers, as well as environmental technology professionals. Although this diverse group is technically astute, not all users of the document will be subject-area experts for the various technologies discussed. This fact poses a significant challenge to achieve an appropriate level of technical detail. To the extent possible, enhancement technologies are covered succinctly in the main body of the document. However, supplemental information on many enhancements has been included in Appendix A so that readers seeking additional information and references can find them easily. WSRC-STI-2006-00083, Rev ORGANIZATION OF THE REPORTAn overview of the purpose of the document is presented in Section 1. The conceptual framework and organizing principles of enhancements to natural attenuation of cVOCs in the subsurface are presented in Section 2. This section contains a summary discussion of different classes of enhancements and the concept of enhancement zones is introduced. The objective of Sectio...

“…The depth to water at the Hill site is approximately 100 feet bgs (Battelle, 1995). At the Savannah River Site in South Carolina, air flow rates from an extraction well were as high as 6 cfm at a site with a depth to groundwater of approximately 120 feet bgs (Rossabi et al, 1993;Rossabi et al, 1998).…”

“…Previous field tests have shown that daily changes in barometric pressure cause open vadose wells to inhale and exhale air (sometimes termed "barometric pumping" or "breathing") (Pirkle et al, 1992;Rossabi et al, 1993, Foor et al, 1995Zimmerman et al, 1997). This phenomenon is illustrated on Figure 3.…”
