Treatment Technologies
The preliminary assessment of remediation technologies feasible for reclamation of subsurface environmental media contaminated with TCE must involve consideration of the compound's physical and chemical properties (i.e., distribution coefficients, reactivity, solubility, etc.). These properties are directly responsible for behavior, transport, and fate of the chemical in the subsurface environment. Knowledge of a compound's physico-chemical tendencies can be used to alter behavior and fate of that compound in the environment.
TCE contamination frequently is addressed with pump-and-treat systems for remediation and containment of the dissolved-phase plume, but some innovative technologies have demonstrated a capacity for fairly rapid removal of mass from DNAPL source zones, and others have treated dissolved-phase contamination successfully. Approaches applied to the remediation of TCE and other DNAPLs include bioremediation, electrokinetics, flushing technologies (cosolvent/alcohol flooding, surfactant flushing, in situ oxidation), monitored natural attenuation, phytoremediation, thermal processes (steam injection, electrical heating, in situ vitrification), volatilization technologies (soil vapor extraction, air sparging, in-well stripping), and treatment walls. Additional information, including site-specific reports, is available at Technology Focus.

The DNAPL Remediation Challenge: Is There a Case for Source Depletion?
EPA 600-R-03-143, 2003
Releases of Dense Non-Aqueous Phase Liquids (DNAPLs) at a large number of public and private sector sites in the United States pose signifi cant challenges in site remediation and long-term site management. Extensive contamination of groundwater occurs as a result of signifi cant dissolved plumes generated from these DNAPL source zones that vary in size and complexity depending on site characteristics and DNAPL properties and distribution. Risk and liability management, consistent with regulatory compliance requirements, could involve remediation of the source zone as well as management of the dissolved plume.

Enhanced Attenuation: Approaches to Increase the Natural Treatment Capacity of a System
Tom Early, et al.
WSRC-TR-2005-00198, 161 pp, 2006
This guide covers the following EA approaches: (1) hydraulic manipulation to reduce contaminant infiltration using low-permeability barriers, diffusion barriers, covers, encapsulation, and diversion of electron acceptors; (2) passive residual source reduction (e.g., bioventing); (3) increase in system attenuation capacity via biological processes, such as bioaugmentation, biostimulation, and wetlands development and other plant-based methods; (4) abiotic and biologically mediated abiotic attenuation methods; and (5) reactive barriers.
Enhanced Attenuation: Chlorinated Organics
Interstate Technology and Regulatory Council (ITRC) Enhanced Attenuation: Chlorinated Organics Team. EACO-1, 109 pp., Apr 2008.
This report was produced by the Interstate Technology and Regulatory Council (ITRC). Many sites with chlorinated organic contamination in groundwater have gone through extensive remedial evaluations and actions. The remedial alternatives for many of these sites include high-energy treatments such as pump-and-treat systems. After years of operation, the effectiveness of these high-energy processes has begun to diminish without remedial objectives being met. Other more effective remedial alternatives need to be implemented; however, there is a lack of guidance available to regulators and the environmental community regarding how and when to transition these sites to lower-energy remedial alternatives and eventually to monitored natural attenuation (MNA). To answer this need, the ITRC Enhanced Attenuation: Chlorinated Organics (EACO) Team developed this guidance, which includes a protocol to assist in a smooth transition (or a bridge) between aggressive remedial actions and MNA.

Strategies for Monitoring the Performance of DNAPL Source Zone Remedies
Interstate Technology and Regulatory Council (ITRC) Dense Nonaqueous-Phase Liquids Team. DNAPLs-5, 206 pp., Aug 2004.
This document is intended for regulators and others interested in learning about approaches to performance monitoring while implementing various in situ technologies for the treatment of DNAPLs. In this document, we present a number of ways in which the success or failure in treating a DNAPL source zone has been measured. Because the vast majority of experience in DNAPL source zone remediation has been in unconsolidated geologies, such as sands and silts, many of the conclusions, recommendations, and lessons learned presented in this document do not necessarily transfer to performance assessment in fractured bedrock, karst, or other consolidated geologies.

In-well vapor stripping and in situ aerobic cometabolic bioremediation were combined to address a TCE source area without bringing contaminated ground water to the surface.
DCE Stall Tool
U.S. Navy, Naval Facilities Engineering Command, Environmental Restoration Technology Transfer, Multimedia Training Tools website.
The reductive dechlorination of perchloroethene (PCE) and trichloroethene (TCE) yields dichloroethene (DCE), vinyl chloride (VC), and ethene. When the reductive dechlorination process is incomplete, the levels of DCE and VC in ground water can build up over time. This process is referred to as DCE stall, and it can limit the ability to meet cleanup goals and obtain site closure. This training tool discusses the suspected causes of DCE stall, along with potential solutions for this problem. DCE stall is typically caused by insufficient electron donor to achieve strongly reducing conditions. Under less reducing conditions, the DCE concentrations in ground water may accumulate without the apparent accumulation of VC, ethene, or ethane. At these sites, biological activity may be hindered by lack of sufficient electron donor or affected by pH, the presence of biotoxins, micronutrient limitations, and other factors. It also is possible that the expected products of VC and ethene are not formed because microbial oxidation or abiotic pathways are dominant (e.g., DCE transformation directly to carbon dioxide). All of these factors should be carefully considered before exploring a biostimulation or bioaugmentation approach at a given site.

The demonstration to evaluate the technical and cost performance of the bioremediation technologies when applied to a TCE DNAPL source zone began in June 2002 and ended in February 2003. Sequential application of biostimulation (ethanol as electron donor) and bioaugmentation (the KB-1 consortium) was evaluated in the same small test plot beneath a building. The treatments significantly decreased total TCE and DNAPL mass in the target treatment zone.
The Effect of Concentrated Electron Donors on the Solubility of Trichloroethene
E. Hood, D. Major, and G. Driedger.
Ground Water Monitoring & Remediation, Vol 27 No 4, p 93-98, 2007
Although recent vendor claims suggest that the addition of highly concentrated electron donor solutions to increase the aqueous solubility of TCE during enhanced in situ bioremediation is a significant mechanism of contaminant mass removal, the results of experimental measurements of the solubility of TCE in aqueous solution with 8 typical electron donors suggest that due to the small changes in TCE solubility in comparison to the high electron donor concentrations employed, it is difficult to envision circumstances justifying the use of a high electron donor concentration to enhance TCE solubility as part of a bioremediation strategy, though the use of more concentrated (e.g., 50 to 95%) ethanol solutions would be appropriate for cosolvent flooding.
Final Report for the Enhanced Anaerobic Bioremediation Pilot Test, Bountiful/Woods Cross Superfund Site, Bountiful, Utah
Bureau of Reclamation, Denver, CO. 66 pp, 2006
This biostimulation/bioaugmentation pilot study to address TCE contamination involved a side-by-side comparison in 3 test cells of 3 different bioremediation substrates: sodium lactate, chitin, and emulsified soybean oil. Following the first round of substrate injection and sampling, all 3 test cells were inoculated with a commercially available dechlorinating culture containing Dehalococcoides ethenogenes. Based on the results of the pilot test, full-scale enhanced anaerobic bioremediation was selected for the site's 2006 Record of Decision. Emulsified oil is recommended as the electron donor.
In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones
Interstate Technology & Regulatory Council (ITRC), Bioremediation of DNAPLs Team. BioDNAPL-3, 138 pp, June 2008
This publication systematically lays out the technical and related regulatory considerations for in situ bioremediation (ISB) of chlorinated ethene dense DNAPL source zones, providing information related to site characterization requirements, treatment system application and design criteria, process monitoring, and process optimization. The ability of ISB technology to enhance the dissolution and desorption of nonaqueous-phase contaminants to the aqueous phase, where they can be degraded by the microbial population, depends on the spatial distribution of DNAPL mass in the subsurface (e.g., pool/ganglia ratio) and the ability to deliver amendments throughout this architecture.

Long-term ground-water monitoring results collected in December 2003 and March 2004 indicate that the EZVI treatment had a long-lasting effect on the chlorinated contaminants in the subsurface. TCE, cis-1,2-DCE, and (eventually) VC levels declined sharply in the one year following EZVI injection, and ethene levels increased substantially.
Nanoscale Zero Valent Iron Training Tool
U.S. Navy, Naval Facilities Engineering Command, Environmental Restoration Technology Transfer, Multimedia Training Tools website, 32 pp.
Zero-valent iron (ZVI) is a strong reducing agent. Nanoscale iron particles typically have surface areas up to 30 times greater than larger-sized granular iron and are up to 1,000 times more reactive for the degradation of chlorinated organic compounds. NZVI is ideally suited for treating chlorinated organic compounds and dense nonaqueous-phase liquid (DNAPL) "hot spots" through injection directly into the source area of contamination. A slurry of NZVI can be distributed into the subsurface using a variety of carrying fluids that help the iron powders disperse into the subsurface and create contact between the contaminants and the iron particles. This training tool discusses injection methods, specific aspects of implementation, NZVI economics, advantages and limitations of the technology, and lessons learned.

Technical Protocol for Enhanced Anaerobic Bioremediation Using Permeable Mulch Biowalls and Bioreactors
Air Force Center for Engineering and the Environment (AFCEE), 302 pp, 2008
Biowall substrates are typically low-cost materials (mulch, compost). The substrates are mixed with common construction materials (sand, gravel) to prevent compaction and maintain permeability. Amendments can be added to stimulate both biotic and abiotic degradation processes, based on the type of contaminant(s) present and the desired degradation pathway(s) to be stimulated. The technology can be applied in source areas or use groundwater recirculation to capture deeper plumes in an in situ bioreactor configuration. Appendix F provides three example case studies evaluating system performance for remediation of chlorinated solvent contamination in ground water: (1) a pilot-scale dual permeable mulch biowall system to address TCE, cis-DCE, and VC at Seneca Army Depot, NY; (2) a permeable mulch biowall to address TCE and cis-DCE at Altus AFB, OK; and (3) a pilot-scale recirculation bioreactor to address TCE, cis-DCE, and VC at Altus AFB.

An interim action was selected in 2004 to remove residual TCE source material by ERH technology coupled with SVE, with subsequent monitoring to determine the rate of decrease in the contaminant plume's concentration. A portable ERH/SVE system was deployed at multiple locations around the site. Extensive data were obtained from the first deployment, which heated the vadose zone down to 62 ft bgs over a 60-day period during the summer of 2006 and raised soil temperatures to over 200 degrees F. This treatment extracted 730 lbs of TCE, and subsequent sampling indicated a removal efficiency of 99.4%.
