Your Role in Green Remediation Implementation and Case Studies in Green Remediation - This Year's Models and Tools (The 2010 NARPM Green Remediation Session Follow-on Webinars) - February 10, 2011, 1:00PM-3:15PM EST (18:00-20:15 GMT). In May 2010, EPA held its annual National Association of Remedial Project Managers (NARPM) meeting in Crystal City, VA, and for the third year in a row, one of our most attended sessions was on Green Remediation (GR). And like last year, we are offering those talks again to an online audience! EPA's definition of GR includes the practice of considering the environmental effects of a remediation strategy (i.e., the remedy selected and the implementation approach) early in the process, and incorporating options to maximize the net environmental benefit of the cleanup action. We've got more case studies and maturing policy and guidance that we'd like to share with an online audience. EPA's Technical Support Project, led by the Engineering Forum, has taken this full-day session and split it into three separate sessions that started in December. This last session is scheduled to be two hours and fifteen minutes long and will include policy and case studies, with time for Q&A along the way. For more information and to register for the last session, see .

Contaminated Sediments: New Tools and Approaches for in-situ Remediation - Session IV - February 14, 2011, 2:00PM-4:00PM EST (19:00-21:00 GMT). This seminar will feature SRP grantees Dr. Harold D. May and Dr. Danny Reible. Dr. May, Professor, Microbiology and Immunology, Medical University of South Carolina will present "Integrating Microbial Biostimulation and Electrolytic Aeration to Degrade POPs" and Dr. Reible, Bettie Margaret Smith Professor of Environmental Health Engineering, Department of Civil, Architectural and Environmental Engineering, University of Texas will present "Enhancing Biodegration in Sediment Caps Using Carbon Cloth Electrodes." Dr. May will discuss bioaugmentation of Fox River (WI) sediment contaminated with polychlorinated biphenyls (PCBs) and persistent organic pollutants (POPs), and testing with bioactive granulated activated carbon (GAC) containing PCB dechlorinating and degrading bacteria. He will also describe how electron donors and acceptors for microbial PCB dechlorination and degradation can be delivered electrochemically to further stimulate the biodegradation of these POPs. These methods show significant reductions in the concentration of weathered PCBs. Dr. Reible will show that although sediment capping is normally considered strictly a contaminant containment technology, it can trigger microbial processes to transform or detoxify both inorganic and organic contaminants. He will describe research exploring these microbial processes and ways of improving their effectiveness. The presentation will focus on how to enhance microbial transformation of hydrophobic organic compounds in sediment caps through the use of electrodes to change terminal electron acceptors and redox conditions.

ITRC Quality Considerations for Munitions Response Projects - February 15, 2011, 2:00PM-4:15PM EST (19:00-21:15 GMT). This training introduces state regulators, environmental consultants, site owners, and community stakeholders to Quality Considerations for Munitions Response Projects (UXO-5, 2008), created by the ITRC's Unexploded Ordnance (UXO) Team. In this document, quality is defined as "conformance to requirements." To manage quality, the quality requirements of the project must first be understood. Requirements must be precisely stated and clearly understood by everyone involved. A plan is then put in place to meet those requirements. The UXO Team emphasizes taking a whole-system approach to designing, planning and managing a munitions response (MR) project to optimize quality. This training course is intended for an intermediate audience and assumes a basic understanding of specialized processes associated with MR projects. For more information and to register, see or .

Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators can use to objectively assess, design, monitor, and optimize ISB treatment of DNAPL source zones. For more information and to register, see or .

ITRC Mine Waste Treatment Technology Selection - February 24, 2011, 11:00AM-1:15PM EST (16:00-18:15 GMT). ITRC's Mining Waste Team developed the ITRC Web-based Mine Waste Technology Selection site ( to assist project managers in selecting an applicable technology, or suite of technologies, which can be used to remediate mine waste contaminated sites. Decision trees, through a series of questions, guide users to a set of treatment technologies that may be applicable to that particular site situation. Each technology is described, along with a summary of the applicability, advantages, limitations, performance, stakeholder and regulatory considerations, and lessons learned. Each technology overview links to case studies where the technology has been implemented. In this associated Internet-based training, instructors provide background information then take participants through the decision tree using example sites. Project managers, regulators, site owners, and community stakeholders should attend this training class to learn how to use the ITRC Web-based Mine Waste Technology Selection site to identify appropriate technologies, address all impacted media, access case studies, and understand potential regulatory constraints. For more information and to register, see or .

Unified Statistical Guidance - February 28, 2011, 2:00PM-4:00PM EST (19:00-21:00 GMT). The webinar will provide interested parties a broad introduction to the March 2009 Unified Guidance. The session will start with the purposes of the guidance and a summary of how it is organized. Speakers will provide a brief discussion on how the guidance might be used for diagnostic evaluation of data assumptions. Next, speakers will expand on a number of key guidance topics: statistical design and hypothesis testing: how to set-up statistical testing to simultaneously identify "dirty" groundwater with sufficiently high probability while minimizing the chance of labeling "clean" groundwater as "dirty"; the importance of background data: when might "moving windows" be needed? How should background be updated for intrawell testing? What if background levels are higher than compliance standards?;
resampling and retesting: what benefits does retesting provide? How can it be done right?; and intrawell testing: why is spatial variation important? How can it be "fixed"?
At the end of the presentation, time will be left for either phone-in or written questions. For more information and to register, see .

Innovations in Site Characterization: Streamlining Cleanup at Vapor Intrusion and Product Removal Sites Using the Triad Approach: Hartford Plume Site, Hartford, Illinois (EPA 542-R-10-006). Vapor intrusion from widespread hydrocarbon plumes at the Hartford Plume Site in the Village of Hartford, Illinois, resulted in numerous residential housing fires and forced residents to move from their homes. To address public concerns at the Site, EPA Region 5 worked with oil company stakeholders from the area and used the best management practices (BMPs) of EPA's Triad Approach to expedite the investigation, mitigation, and cleanup processes. The Hartford Plume Site case study provides a detailed example of the strategies and technologies used at the site that are available to environmental practitioners to use at large and small hydrocarbon sites. Sufficient detail is provided for practitioners to learn the basic elements of designing and implementing site characterization, mitigation, and remedial efforts at complex hydrocarbon sites (September 2010, 359 pages).

The Incorporation of an Ecosystem Services Assessment into the Remediation of Contaminated Sites. This document was prepared by Sarah Slack, a National Network for Environmental Management Studies (NNEMS) grantee under a fellowship from the U.S. EPA. This report recommends an approach for assessing a site's ecosystem services (the benefits that humans derive from ecosystems) prior to site remediation as a means to qualitatively or quantitatively track ecosystem changes associated with cleanup activities and to identify opportunities for avoiding or mitigating a cleanup project's negative effect on the ecosystem. Based on literature research and personal communications, the report presents background information on the concept of ecosystem services, as well as steps interested parties can take to mitigate or avoid impacts to ecosystem services at a site level throughout the remediation process. The report outlines replicable practices that remedial project managers can utilize when attempting to mitigate adverse impacts on an ecosystem. This report also describes the current state of data collection methods and issues pertinent to the ecosystem service assessment process, with the ultimate aim of fostering production of a replicable methodology that can lead to greener cleanups (August 2010, 34 pages).

Practical Models Supporting Remediation of Chlorinated Solvents, Atlanta, GA, March 22-23, 2011. Explore a subset of the publicly-available simulation and data analysis tools that can be used alone or in combination to answer questions such as: Will source remediation meet site goals? What will happen if no action is taken? Should I combine source and plume remediation? What is the remediation timeframe? What is a reasonable remediation objective? The model discussion will focus on the unique features of selected models and how those features can support strategy development. Emphasis will be on REMChlor, a newly released tool that simulates both source and plume remediation. By providing the ability to simulate sites where conditions change in space and time, REMChlor can provide information equivalent to the types of output from more sophisticated numerical models.
