ITRC In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones - September 9. 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 http://www.itrcweb.org or http://clu-in.org/studio .

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems - September 11 and October 8. This seminar presents a systematic approach for the evaluation of capture zones at pump and treat systems, and provides an overview of a recently published USEPA document on the topic (EPA 600/R-08/003, January 2008). The target audience is project managers who review those analyses and/or make decisions based on these types of analyses. This course will highlight: the importance of capture zone analysis during ground water remediation, particularly for sites requiring containment; key concepts of capture, such as "target capture zones" and "converging lines of evidence;" and typical errors made in capture zone analysis. Examples will be used to demonstrate key aspects of capture zone analysis. For more information and to register, see http://clu-in.org/studio .

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool - September 11. 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. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/studio .

Triad: Beyond Characterization to Long-term Management of Groundwater Contaminant Plumes - September 12. This workshop is similar to one presented at the June 2008 Triad Conference. It will cover field analytical approaches, followed by LTM network design and implementation, then integration of sensors and logistics into the development of the CSM, and will finally wrap up with examples of automated monitoring (which includes contouring and model update). This workshop will cover best-of-class approaches for CSM development with an emphasis on direct-push technologies, then integrate new approaches to update this in the most time/cost-effective manner. While the models are conceptual, the workshop will discuss analytical components to the model to make quantification possible. For more information and to register, see http://clu-in.org/studio .

Long-Term Monitoring Optimization (LTMO) Training - September 24. EPA is partnering with the U.S. Army Corps of Engineers to offer a live Internet seminar focusing on new methods of optimizing groundwater monitoring. State, tribal, and federal regulators, federal facilities cleanup managers, potentially responsible parties (PRPs), and contractors are invited to participate. Responsible parties, federal facilities, and EPA have used LTMO methods at more than 100 sites nationwide and are likely to use them at more sites in the future. These methods support decision-making regarding optimal location and frequency of groundwater monitoring and support changes to existing monitoring networks. The seminar will define and describe long-term monitoring optimization and how it can be used to demonstrate progress toward remedial goals and will include a case study illustrating LTMO topics presented. This seminar is presented jointly by the U.S. EPA Office of Superfund Remediation and Technology Innovation (OSRTI) and the U.S. Army Corps of Engineers. For more information and to register, see http://clu-in.org/studio .

Tree Coring to Assess Subsurface Volatile Organic Compounds - September 25. Analysis of the volatile organic compound content of tree cores is an inexpensive, rapid, simple approach to examining the distribution of subsurface volatile organic compound contaminants. The method has been shown to detect several volatile petroleum hydrocarbons and chlorinated aliphatic compounds associated with vapor intrusion and ground-water contamination. Tree cores are obtained by using an increment borer. The cores are placed in vials and sealed. After a period of equilibration, the cores can be analyzed by headspace analysis gas chromatography. Don Vroblesky of the United States Geological Survey will discuss the recently published "User's Guide to the Collection and Analysis of Tree Cores to Assess the Distribution of Subsurface Volatile Organic Compounds" that describes the method. The guide helps environmental professionals unfamiliar with the tools and methods of tree coring and contributes understanding to the relevant underlying tree physiology. For more information and to register, see http://clu-in.org/studio .

ITRC Evaluating, Optimizing, or Ending Post-Closure Care at Municipal Solid Waste Landfills - September 25. This training, based on ITRC's Technical and Regulatory Guidance: Evaluating, Optimizing, or Ending Post-Closure Care at Municipal Solid Waste Landfills Based on Site-Specific Data Evaluations (ALT-4, 2006), describes a method to evaluate the performance of Post Closure Care at a landfill and determine when leachate recovery, landfill gas management, groundwater monitoring, and cap maintenance can be reduced or even ended based on threats (to human health and the environment) posed by the closed landfill. The training and document describe custodial care as those requirements the property owner must follow after post closure care has been ended.
