> Upcoming Live Internet Seminars

ITRC Perchlorate Remediation Technologies -October7, 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. For more information and to

register, see http://www.itrcweb.ora Or http://clu-in.ora/live .

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

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. For more information and to register, see

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. For
more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

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. For more information and to register, see http://ciu-in.ora/iive .

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

TechDirect: October 1, 2010

-------
CSIA as presented in Parts 1 and 2, available at http://www.ciu-in.ora/iive/archive/. Part 3 of the
webinarwill 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 webinarwill 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. For more information
and to register, see http://ciu-in.ora/iive .

> New Documents and Web Resources

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. View and use at http://www.ciu-in.ora/nano .

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). View or download at http://ciu-in.ora/asr.
