Title: Soil Vapor Extraction System Optimization, Transition, and Closure Guidance

Abstract

Soil vapor extraction (SVE) is a prevalent remediation approach for volatile contaminants in the vadose zone. A diminishing rate of contaminant extraction over time is typically observed due to 1) diminishing contaminant mass, and/or 2) slow rates of removal for contamination in low-permeability zones. After a SVE system begins to show indications of diminishing contaminant removal rate, SVE performance needs to be evaluated to determine whether the system should be optimized, terminated, or transitioned to another technology to replace or augment SVE. This guidance specifically addresses the elements of this type of performance assessment. While not specifically presented, the approach and analyses in this guidance could also be applied at the onset of remediation selection for a site as a way to evaluate current or future impacts to groundwater from vadose zone contamination. The guidance presented here builds from existing guidance for SVE design, operation, optimization, and closure from the U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, and the Air Force Center for Engineering and the Environment. The purpose of the material herein is to clarify and focus on the specific actions and decisions related to SVE optimization, transition, and/or closure.

    The U.S. Environmental Protection Agency's Office of Air Quality Planning and Standards and the Regional Air Offices have been given the responsibility to evaluate air impacts from Superfund sites. The report provides procedures for roughly estimating the ambient air concentrations associated with soil vapor extraction (SVE). The procedures for SVE systems are analogous to procedures for air strippers that have previously been published. SVE is also known as soil venting, vacuum extraction, aeration, or in-situ volatilization. It is a widely used technique for removing volatile organic compound (VOC) vapors from contaminated soil. Procedures are given to evaluate the effect ofmore » the concentration of the contaminants in the soil-gas and the extraction rate on the emission rates and on the ambient air concentrations at selected distances from the SVE system.« less

  • Section 121(b) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) mandates the U.S. Environmental Protection Agency (EPA) to select remedies that 'utilize permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable'. Treatability studies conducted during the RI/FS phase indicate whether a given technology can meet the expected cleanup goals for the site. The document refers to three levels or tiers of treatability studies: remedy screening, remedy selection, and remedy design.

  • This Guide is intended to support decision-making by Regional and State Corrective Action permit writers, Remedial Project Managers (RPMs), On-Scene Coordinators, contractors, and others responsible for the evaluation of technologies. This Guide directs managers of sites being cleaned up under RCRA, UST, and CERCLA waste programs to soil vapor extraction resource documents, databases, hotlines, and dockets and identifies regulatory mechanisms (e.g., Research Development and Demonstration Permits) that have the potential to ease the implementation of soil vapor extraction at hazardous waste sites. The Guide provides abstracts of representative examples of over 70 SVE guidance/policy and reference documents, overview/program documents, andmore » studies and demonstrations. The Soil Vapor Extraction Treatment Technology Resource Matrix, which accompanies this Guide, identifies the contaminants, soil type, and activities used to support the application of SVE covered in each abstracted document.« less
