Soil Vapor Extraction

Application

Adobe PDF Logo100% Design: Thermally Enhanced Soil Vapor Extraction System at Former Chlorobenzene Process Area, W.G. Krummrich Facility, Sauget, Illinois
U.S. EPA Region 5, 112 pp, 2011

This document contains the design basis for implementing full-scale thermally enhanced SVE (T-SVE) treatment to address benzene, monochlorobenzene, 1,2-dichlorobenzene (1,2-DCB), 1,3-DCB, 1,4-DCB, and 1,2,4-TCB. The initially proposed remedy, in situ thermal desorption, was determined to be cost prohibitive. The area targeted for T-SVE treatment covers ~3.5 acres, between ground surface and 15 ft bgs. The total COC mass in the target treatment area is estimated at 440,000 lbs. T-SVE will be implemented using a dual-level SVE and air injection (AI) well network (i.e., shallow and deep well screens). A mixture of steam and air will be injected through the AI wells to heat the subsurface soils to a target temperature ranging between 40 and 60 degrees C, which will increase the volatility of the target COCs and thus mass removal rates. An insulating concrete cap will be installed to reduce heat losses to the atmosphere. Upon completion of the T-SVE operations, bioventing is proposed as an additional treatment measure.

Adobe PDF Logo100% Soil Vapor Extraction System Design: Big Mo & Former Benzene Pipeline Areas, W.G. Krummrich Facility, Sauget, Illinois
U.S. EPA Region 5, 172 pp, 2011

This design document is limited to the application of SVE for benzene and chlorobenzene. A total of 74 SVE wells will be configured so that they can be operated in an air injection (AI) mode. The SVE system will be operated in one of 2 target soil layers at a given time. Seasonal fluctuations of the water table will not allow continuous operation in the lower silty sand layer; therefore, it is more cost-effective to design the SVE system to focus on one target layer at a time. Upon completion of SVE operations, bioventing is recommended as an additional treatment measure. The SVE equipment can be modified for bioventing operations.

REMTECH 2010: The Remediation Technologies Symposium, Banff, AB, Canada, 20-22 Oct 2010. Environmental Services Association of Alberta, Edmonton, AB (Canada), 21 slides, 2010

A wind-powered pilot SVE system with a single well extraction unit was used successfully to remove petroleum hydrocarbons trapped in the subsurface at a site located in Central Alberta, Canada. The top 1 to 2 m of bedrock (interbeded sandstone, siltstone, and shales) is highly weathered and soft but becomes hard and fractured with depth. Groundwater lies at a depth of 6-8 m bgs. The three main system components were (1) a vertical windmill, including drive shaft, (2) a 4-cylinder membrane pump, and (3) one extraction well screened at 6-12m bgs above the water table into sandstone.

Sustainable Remediation 2011: State of the Practice — International Conference, June 1-3, 2011, University of Amherst, Massachusetts. 8 pp and 29 slides, 2011

Life-cycle analyses (LCAs) were conducted for four sites in Germany where SVE was later followed by in situ thermal remediation (ISTR) using steam injection (3 sites) or conductive heating (1 site), and at one site in Denmark, where SVE and ISTR were compared with excavation/off-site treatment, and SVE was again followed by ISTR. (In situ thermal desorption was eventually implemented at the Denmark site.) Site-specific conditions varied, but each of the LCAs showed that SVE consumed more energy, produced more waste, and generated more greenhouse gases than ISTR, while requiring a lengthy or even indefinite period of time to achieve site closure.

REMTECH 2010: The Remediation Technologies Symposium, Banff, AB, Canada, 20-22 Oct 2010. Environmental Services Association of Alberta, Edmonton, AB (Canada), 43 slides, 2010

During distillery operations at the site from the 1950s to the early 1980s, backup fuel supplies (furnace oil/diesel) leaked into the soil and groundwater. In the late 1980s, the site was redeveloped into a strip mall whose southwest wing, referred to as the CRU-D building, was constructed atop the contaminated soil and groundwater. Previous consultants installed an in situ AS/SVE system to the west of and beneath the CRU-D building in 1997 and operated it until August 2008. Between September 2008 and December 2009, SLR completed delineation of soil and groundwater contamination beneath and around the CRU-D building, reviewed all site data, and designed a new in situ AS/SVE remedial system that targeted the optimal areas, depths, and soil units, with dedicated piping for each sparge and extraction line and higher capacity blowers and compressors to achieve optimal pressures and flow rates. Installation and startup of the new remedial system took place between January and May 2010. This presentation describes the challenges and logistics of drilling at an occupied/operating mall; the management and reduction of remediation system sound levels from equipment to comply with local bylaws; and the challenges and successes of system optimization and effectiveness.

J. Solc and B.W. Botnen.
2009-EERC-03-03, 55 pp, 2009

Remediation of hydrocarbon-contaminated soils and groundwater was conducted at the Vining Oil site in Carrington, ND, via simultaneous operation of MPE and high-vacuum SVE contaminant recovery coupled with vacuum-controlled air and ozone sparging on the periphery of an induced hydraulic and pneumatic depression. Integration of the air-sparging subsystem operated simultaneously with MPE and SVE systems resulted in accelerated transport of volatile organics from the saturated zone and increased recovery of contaminants of concern. Delivery of over 7.7 million cubic ft of oxygen into the contaminated aquifer resulted in in situ biodegradation of benzene and provided for long-term stimulation of contaminant attenuation. Monitoring results from September 2006 to June 2008 are reported.

JV Task 109: Risk Assessment and Feasibility of Remedial Alternatives for Coal Seam at Garrison, North Dakota
J. Solc.
2007-EERC-12-07, 300 pp, 2007

The performance of SVE and multiphase extraction (MPE) for remediation of soil and ground water impacted by a hydrocarbon-contaminated coal seam was evaluated in Garrison, North Dakota, following the September 2005 release of an estimated 30,000 gallons of premium gasoline from an oil company facility. Free product was detected in cavities of the abandoned mine, as well as high concentrations of residual gasoline-based contaminants. SVE and MPE pilot tests confirmed high contaminant recovery efficiency at all three of the identified hot spots. The suggested remedial strategy is based on contaminant recovery and in situ degradation using a combination of thermally enhanced SVE in the source area, mobile MPE units transitioned to SVE in saturated impacted areas, and high-volume low-vacuum extraction from mining cavities based on a pioneering concept of controlled 'draft and channel' extraction technology.

The successful removal of VOCs (carbon tetrachloride, Freon 113, trichloroethene, and 1,1-dichloroethene) from the vadose zone during an SVE pilot test in 1998 led NASA to proceed with this alternative using a trailer-mounted unit that was moved among 4 locations from April 1998 until September 2005. The system achieved all of its specified performance objectives.

Adobe PDF LogoRemedial Action Status Report: McNatt's Cleaners, 5297 Ehrlich Road, Tampa, Hillsborough County, Florida
Florida Department of Environmental Protection, 278 pp, 2018

The facility is an active drycleaner that currently uses petroleum-based drycleaning solvent. The remediation system is designed to recover PCE and daughter products identified in the vadose zone. Although multi-phase extraction was initially recommended as a remedial technology, a phased remedial approach was selected that began in 2004 with the design and implementation of a soil vapor extraction (SVE) system to remediate shallow soils and was followed in 2009 with injections of biostimulation materials (SRS®). Installation of an additional SVE well and completion of additional biostimulation and bioaugmentation injections took place in 2017. Contaminant mass removal through the most recent reporting period is estimated at ~444.9 lbs and appears to have leveled off. Additional information: McNatt Project Website
