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
. A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems - November 13, 2:00PM-4:00PM EST (19:00-21:00 GMT). 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 In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones - November 13, 11:00AM-1:15PM EST (16:00-18:15 GMT). 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

introduces ITRC's Technical/Regulatory Guidance, Decontamination and Decommissioning of Radiologically-Contaminated Facilities (RAD-5, 2008), created
by ITRC's Radionuclides Team. The curriculum is composed of four modules: Introduction and Regulatory Basis for Decontamination and Decommissioning (D&D),
Factors for Implementing D&D, Preliminary Remediation Goal (PRG) Calculators, and Case Studies and Lessons Learned. For more information and to register,
see http://www.itrcweb.org or http://clu-in.org/studio . ITRC Planning and Promoting of Ecological Land Reuse of Remediated Sites - November 20, 11:00AM-1:15PM EST (16:00-18:15 GMT). This training is based on
the ITRC Technical and Regulatory Guideline: Planning and Promoting Ecological Land Reuse of Remediated Sites (ECO-2, 2006). The document presents a process
to promote ecological land reuse activities considering natural or green technologies instead of more traditional remedies. The guidance demonstrates
that natural or ecological end-uses are valuable alternatives to conventional property development or redevelopment. Ecological benefits and a process
for calculating their value are included in the guidance and reviewed in this training. For more information and to register, see http://www.itrcweb.org

GMT). In July, EPA held its annual National Association of Remedial Project Managers meeting in Portland, OR and one of our most attended sessions was on Green
Remediation (GR). Because of its success, members of EPA's Technical Support Project, led by the Engineering Forum, have taken this full-day session and are
bringing back a number of the same talks as online seminars this fall and winter. There will be three sessions, each 1.5 hours long. 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. Some practices are quite 'mature,' such as construction
site best management practices including stormwater runoff management and construction and demolition (C&D) debris recycling. Others are still emerging,
including the use of renewable energy sources such as wind and solar to power remedial systems. Over the three sessions, the online training will introduce
you to the key technical, policy, and application aspects of GR. For more information and to register, see http://clu-in.org/studio . ITRC Performance-based Environmental Management - December 2, 2:00PM-4:15PM EST (19:00-21:15 GMT). Performance-based environmental management (PBEM)
is a strategic, goal-oriented methodology that is implemented through effective planning and decision logic to reach a desired end state of site cleanup.
The goal of PBEM is to be protective of human health and the environment while efficiently implementing appropriate streamlined cleanup processes. This ITRC
training presents an overview of what PBEM is, explains how and when to implement it, and describes the issues that regulators are concerned about throughout
PBEM's implementation. Case studies will be presented to illustrate successful PBEM projects. The course is valuable not only because PBEM is being proposed
and implemented at many federal and private sites throughout the country, but also because PBEM provides an opportunity to enhance all site remediation. For

July, EPA held its annual National Association of Remedial Project Managers meeting in Portland, OR and one of our most attended session
