Soil Vapor Extraction


Adobe PDF LogoAnalysis of Selected Enhancements for Soil Vapor Extraction
EPA 542-R-97-007, 1997

This report provides an engineering analysis of, and status report on, selected enhancements for the following soil vapor extraction (SVE) treatment technologies: air sparging, dual-phase extraction, directional drilling, pneumatic and hydraulic fracturing, and thermal enhancement. It also offers an evaluation of each technology's applicability to various site conditions, cost and performance information, a list of vendors specializing in the technologies, a discussion of relative strengths and limitations of the technologies, recommendations to keep in mind when considering the enhancements, and extensive references.

R. Kamath, D.T. Adamson, and C.J. Newell.
SRNL-STI-2009-00571, 88 pp, 2009

Passive soil vapor extraction (PSVE) usually is driven by natural pressure gradients between the subsurface and atmosphere (barometric pumping) and sometimes by renewable sources of energy, such as wind or solar power (assisted PSVE). PSVE is applicable for remediating sites with low levels of contamination and for transitioning sites from active source technologies, such as active SVE, to natural attenuation. This technology report summarizes the relevant technical background, real-world case study performance, key design and cost considerations, and a scenario-based cost evaluation.

Adobe PDF LogoEvaluation of Soil Venting Application
DiGiulio, D.C.
EPA 540-S-92-004, 7 pp, 1992

While the application of soil vacuum extraction is conceptually simple, its success depends on understanding complex subsurface physical, chemical, and biological processes, such as contaminant volatility, mass transport limitations, and soil permeability and liquid content, that provide insight into factors limiting venting performance.

Adobe PDF LogoOff-Gas Treatment Technologies for Soil Vapor Extraction Systems: State of the Practice
EPA 542-R-05-028, March 2006

This document provides state-of-the-practice information on off-gas treatment technologies for soil vapor extraction systems currently being used to clean up hazardous waste sites. It provides information on common practices such as carbon adsorption and thermal oxidation, less frequently used technologies such as biofiltration, and emerging alternatives including photocatalytic and non-thermal plasma treatment. The report presents the state of the practice for these technologies based on applicability, limitations, performance, engineering considerations, residuals management, cost and economics, and developmental status.

Presents an option for expediting and encouraging cleanup of sites with chlorinated VOCs in vadose zone soil by streamlining the cleanup process. This approach limits the number of evaluated technologies to excavation/disposal and SVE and provides resources to facilitate the design and implementation of both remedies. Considerations for operation and maintenance of SVE systems, including zone of capture assessment, operational assessment, and shutdown and cleanup confirmation are included.

PNNL-21843, 130 pp, 2013

After an SVE system begins to show indications of diminishing contaminant removal rate, SVE performance is evaluated to determine whether the system should be optimized, terminated, or transitioned to another technology to replace or augment SVE. This text specifically addresses the elements of this type of performance assessment to clarify and focus on the specific actions and decisions related to SVE optimization, transition, and/or closure. The Soil Vapor Extraction Endstate Tool (SVEET) is a spreadsheet tool that allows the user to easily enter data and calculate the estimated groundwater concentration for one or more scenarios conforming to the generalized conceptual model described in the report. This software provides a convenient method for the user to apply the calculation procedures described in Appendix C of the guidance report (which also walks through an example calculation). Appendix D of the report provides details about the SVEET software, including system requirements, installation, the user interface, and application of the software.
