ITRC Perchlorate Remediation Technologies - October 7, 2010, 11:00AM-1:15PM EDT (15:00-17:15 GMT). This training introduces state regulators, environmental consultants, site owners, and community stakeholders to Remediation Technologies for Perchlorate Contamination in Water and Soil (PERC-2, 2008), created by ITRC's Perchlorate Team to assist reviewers in assessing the adequacy of perchlorate remediation projects. This course gives the student a background in the available remediation technologies to treat perchlorate contamination, discusses emerging technologies, and presents case studies of applications.

ITRC LNAPL Training Parts 1, 2, and 3 - October 12, 13, and 14, 2010. Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. Part 1 of this training course explains how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. Part 3 also provides an overview of the LNAPL remedial technology selection framework. For more information and to register, see or .

ITRC Use of Risk Assessment in Management of Contaminated Sites - October 19, 2010, 2:00PM-4:15PM EDT (18:00-20:15 GMT). This training course identifies how various risk-based approaches and criteria are applied throughout the processes of screening, characterization, and management of contaminated sites. The training course and associated overview document, Use of Risk Assessment in Management of Contaminated Sites (RISK-2, 2008), are intended for risk assessors and project managers involved with the characterization, remediation, and/or re-use of sites. The training and overview document provide a valuable tool for federal and state regulatory agencies to demonstrate how site data collection, risk assessment, and risk management may be better integrated.

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool - October 21, 2010, 11:00AM-1:00PM EDT (15:00-17:00 GMT). This training on the ITRC Technical and Regulatory Guidance for Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced attenuation (EA) is the application of technologies that minimize energy input and are sustainable in order to reduce contaminant loading and/or increase the attenuation capacity of a contaminated plume to progress sites towards established remedial objectives. Contaminant loading and attenuation capacity are fundamental to sound decisions for remediation of groundwater contamination. This training explains how a decision framework which, when followed, allows for a smooth transition between more aggressive remedial technologies to sustainable remedial alternatives and eventually to Monitored Natural Attenuation. This training will demonstrate how this decision framework allows regulators and practitioners to integrate Enhanced Attenuation into the remedial decision process.

FY11 Job Training Grant Guidelines, October 26, 2010, 2:00PM-4:00PM EDT (18:00-20:00 GMT). EPA provides funds to eligible entities, including non-profit organizations, to deliver environmental workforce development and job training programs focused on hazardous and solid waste management, assessment, and cleanup associated activities. Environmental Workforce Development and Job Training (EWDJT) grants are provided to recruit, train, and place, unemployed and under-employed, predominantly low-income and minority, residents historically affected by hazardous and solid waste sites and facilities with the skills needed to secure full-time, sustainable employment in the environmental field and in the assessment and cleanup work taking place in their communities. Formerly referred to as the "Brownfields Job Training Grants Program," the "Environmental Workforce Development and Job Training Grants Program," supports expanded environmental training outside the traditional scope of just brownfields but builds upon the existing model and the capacity created through the Brownfields Job Training Program since its inception in 1998.

Applications of Stable Isotope Analyses to Environmental Forensics (Part 3), and to Understand the Degradation of Chlorinated Organic Contaminants (Part 4) - October 27, 2010, 2:00PM-3:30PM EDT (18:00-19:30 GMT). This webinar will consider advanced topics in the applications of compound specific stable isotope analyses (CSIA). It will assume some understanding of the fundamental principles of CSIA as presented in Parts 1 and 2, available at . Part 3 of the webinar will discuss applications of CSIA to various problems in environmental forensics. Many ground water contaminants, such as fuel spills, are complex mixtures of many compounds. CSIA data can be combined with data on concentrations of individual compounds (as determined by conventional GC or GCMS analysis) to associate contamination in ground water plumes with specific sources or releases. The application of CSIA is also extremely valuable for single component contaminants, such as PCE or TCE, where data on concentrations as provided by GC and GCMS are of little or no use for correlation. Part 4 of the webinar will consider the degradation of chlorinated solvents and their transformation products and will focus particularly on the evolution of CSIA as a novel method for investigation of biodegradation at contaminated sites. Stable isotope analysis can provide a direct indication of the effects of degradation on specific contaminants, and in some cases an independent means to quantify the extent of degradation and estimate degradation rates.

New CLU-IN Technology Focus Area on Nanotechnology. EPA has added a new Remediation Technology section to the CLU-IN website called "Nanotechnology: Applications for Environmental Remediation." The purpose of the new website area is to provide easy-to-access information to assist site managers when they are evaluating whether to use nanoscale zero-valent iron or other nanomaterials for hazardous waste site remediation. The website is divided into five sections: Overview, Guidance, Application, Training, and Additional Resources. As new information becomes available, the Nanotechnology: Applications for Environmental Remediation website will be updated with information from federal cleanup programs, state sources, universities, nonprofit organizations, peer-reviewed publications, and public-private partnerships.

Superfund Remedy Report, Thirteenth Edition (EPA-542-R-10-004). The Superfund Remedy Report (SRR), Thirteenth Edition, formerly called the Treatment Technologies for Site Cleanup: Annual Status Report (ASR), was published by the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) in September 2010. The SRR presents the analysis of Superfund remedial actions based on: (1) remedies selected in Records of Decision (ROD) and ROD amendments, and (2) actions modified in Explanation of Significant Differences (ESD), for fiscal years (FY) 2005 - 2008. The SRR also follows trends in remedy selection using ASR data from FY 1982 - 2004 combined with SRR data. The SRR analyzes remedies selected or modified in 594 decision documents, but does not include project-specific updates that were presented in past editions of ASR. In addition, SRR also includes brief project highlights related to green remediation, in situ bioremediation, and high resolution site characterization. The online version includes downloadable appendices with data for several key tables and figures in the report and new appendices that summarize all the remedy components selected for sources and groundwater in each individual decision document (September 2010, 144 pages).
