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.

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.

This report presents the findings, observations, and results from Year 1 operation of the air sparging groundwater interim measure for high-concentration and low-concentration plumes within the perimeter fence line at Launch Complex 39A (LC39A). The objective of the LC39A groundwater IM is to actively decrease concentrations of TCE, cDCE, and VC in groundwater within the pad perimeter fence line to levels less than Florida DEP Groundwater Cleanup Target Levels. This report presents system O&M information from system startup in February 2015 through December 31, 2015, and performance monitoring results for quarterly groundwater sampling events through January 2016.

Single-well push/pull test methods were demonstrated at Fort Lewis Logistics Center (using toluene as a cometabolic growth substrate) and McClellan AFB (during cometabolic air sparging with propane as a growth substrate) to determine (1) the transport characteristics of nutrients, substrates, and CAHs and their transformation products; (2) the capability of indigenous microorganisms to utilize selected substrates and transform targeted contaminants and surrogate compounds; (3) the rates of substrate utilization and contaminant transformation; and (4) the combinations of injected nutrients and substrates that maximize rates of contaminant transformation.

Design, performance, and cost summary data were collected from nine packed-tower and low-profile air stripper treatment systems that address MTBE contamination in ground-water supplies in the 1990s to develop a series of cost and reliability curves and assess the accuracy of two models designed to predict the cost and performance of packed-tower and low-profile air strippers. Results indicate that a variety of different treatment train configurations can use air strippers successfully to remove a range of MTBE concentrations (i.e., from 10 to 2,400,000 ug/L). Removal efficiencies ranged from 65% to greater than 99.9%. The commercially available models predicted actual removal efficiencies within 15%.

Successful Application of Air Sparging to Remediate Ethylene Dibromide (EDB) in Ground Water in Kansas
McGuire, E. and J.T. Wilson.
National Tanks Conference, Boston, Massachusetts, 20-22 September 2010. 33 slides, 2010

In 1995, ethylene dibromide (EDB) was found in Public Water Supply #3 in Selden, KS. Phase I of the remedial design, installed in 1999, had 12 SVE wells screened at different intervals. Initial concentrations of benzene, 1,2-DCA, and EDB in a hot spot well were 2,080, 135, and 115 ug/L, respectively. With treatment, concentrations of EDB and 1,2-DCA decreased 90% or more, but groundwater contamination persisted. In 2007, five new, shallower (top of screen 12 ft below water table) air sparge (AS) wells went on line, replacing existing sparge wells. New SVE wells were also installed. The new sparge wells produced a rapid decrease in concentrations of BTEX, 1,2-DCA, and EDB throughout the area of influence of the remedial system. Longer abstract; Slide presentationAdobe PDF Logo
