This cost estimating tool is intended to assist remedial project managers in evaluating the cost of implementing enhanced anaerobic bioremediation for chlorinated solvents in groundwater. These costs may be useful for comparing system configurations or for comparison to alternative remedial technologies.

This report summarizes the technical and regulatory status of bioaugmentation for chlorinated ethenes, as of May 2005, and identifies research needs to be addressed to facilitate successful widespread use of the technology.

This protocol provides guidance on the use of emulsified edible oils for enhanced in situ anaerobic bioremediation. It is intended to assist base managers and project engineers in determining if the emulsified oil process is appropriate for their site and in designing and implementing the technology.  

This Natural Attenuation Software provides a screening tool for users to estimate remediation time frames for monitored natural attenuation (MNA) to lower groundwater contaminant concentrations to regulatory limits and to assist in decision making on the level of source zone treatment in conjunction with MNA, using site-specific remediation objectives.

The Frequently Asked Questions document provides a concise overview of current knowledge regarding the management of subsurface chlorinated solvent releases and is intended to be used as a support tool for making sound management decisions. An on-demand video providing a summary of this material also is available.

This protocol provides users with information on the fate, transport and transformation of perchlorate in different geochemical environments and describes evaluation technologies as well as a tiered approach for evaluating the potential for monitored natural attenuation (MNA) of perchlorate. 

The DGCHANGE software is a spreadsheet-based tool, designed to estimate dissolved contaminant concentration reductions with time in near-field monitoring wells down-gradient of permeable treatment barriers. The tool has a corresponding User’s Guide that describes the four worksheets focused on model inputs, a cross-section snapshot, and changes with time at a monitoring well.

The Emulsion Design Tool is a spreadsheet-based tool developed to guide the design of emulsified oil distribution systems for enhancing bioremediation of contaminants in groundwater. Also available is an overview presentation on implementing the tool as well as a User’s Guide detailing necessary calculations and the effects of different design parameters on contact efficiency.

This report introduces commonly applied in situ thermal technologies including electrical resistance heating (ERH), in situ thermal desorption (ISTD), steam/hot air injection, and in situ soil mixing combined with steam/hot air injection. It summarizes key information gained from the review of 182 thermal applications. 

This reference book published by Springer describes the process design and engineering for physical, chemical, and biological technologies used to treat complex chlorinated solvent plumes and is based largely on SERDP- and ESTCP-funded efforts. It serves as a reference for decision makers, practicing engineers, and hydrologists who select, design, and operate remedial systems, as well as researchers seeking to improve the state of the art.

The ISCO Technology Practices Manual is comprised of a frequently asked questions (FAQ) guide and an interactive protocol with decision support tools and design models. This manual will enable cost-effective application of ISCO technologies to clean up contaminant source zones and groundwater plumes at DoD sites.

This reference book published by Springer describes the principles and practices of in situ chemical oxidation (ISCO) for groundwater remediation. Chapters are based on a decade of intensive research, development, and demonstrations funded by SERDP, ESTCP, and others, and on lessons learned from commercial field applications. It serves as a reference for decision makers, practicing engineers, and hydrologists who select, design, and operate remedial systems, as well as researchers seeking to improve the state of the art.

This on-demand video provides an overview of the in situ chemical oxidation (ISCO) Technology Practices Manual as presented in a short course at the 2010 SERDP and ESTCP Symposium. ISCO case studies as documented in the scientific literature are summarized and various guidance and decision support tools are discussed.

Application of the guidance and tools can enhance the site-specific engineering of ISCO for remediation of contaminated groundwater and help ensure more predictable, cost-effective performance.

This on-demand video presents a summary of the basic concepts of mass discharge and mass flux, as presented in a short course at the 2010 SERDP and ESTCP Symposium. The course is based on the technology overview document, Use and Measurement of Mass Flux and Mass Discharge, published by the Interstate Technology & Regulatory Council (ITRC). Available measurement and estimation techniques are described, and several case studies of mass flux measurements at contaminated sites are examined.

This reference book published by Springer describes the principles of chemical delivery and mixing systems and their design and implementation for effective in situ remediation. It serves as a reference for decision makers, practicing engineers and hydrogeologists who select, design and operate remedial systems, as well as the researchers seeking to improve the current state of the art.

This on-demand video presents lessons learned from a suite of thermal treatment projects, as presented in a short course at the 2011 SERDP and ESTCP Symposium. The course was designed to promote a more comprehensive understanding of thermal treatment technologies and their potential effects, by highlighting the state of the art and recent advances. 

This reference book published by Springer reviews the past 10-15 years of research and development that have led to bioaugmentation becoming an effective and accepted remedial technology. Decision-making processes for implementing bioaugmentation, design and cost considerations, and monitoring options are described. The book serves as a reference for environmental remediation professionals seeking to understand, evaluate, and implement bioaugmentation.
