TechDirect, March 1, 2010

Welcome to TechDirect! March signals the
beginning our our 15th year delivering TechDirect.

We have been very pleased (and somewhat
surprised) at the continued and steady growth of
our subscribers over the last 14 years. Since the
February 1 message, TechDirect gained 273 new

subscribers for a total of 35,650. If you feel the service is valuable, please share
TechDirect with your colleagues. Anyone interested in subscribing may do so on
CLU-IN at http://ciu-in.ora/techdirect. All previous issues of TechDirect are archived there.
The TechDirect messages of the past can be searched by keyword or can be viewed
as individual issues.

TechDirect's purpose is to identify new technical, policy and guidance resources related
to the assessment and remediation of contaminated soil, sediments and ground water.

Mention of non-EPA documents or presentations does not constitute a U.S. EPA
endorsement of their contents, only an acknowledgment that they exist and may be
relevant to the TechDirect audience.

ITRC Decontamination and Decommissioning of Radiologically-Contaminated
Facilities - March 4, 2010,11:00AM-1:15PM EST (16:00-18:15 GMT). This training
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

ITRC LNAPL Training Parts 1, 2, and 3 - March 9, 11, and 18, 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

Improved Process for Identifying, Prioritizing and Addressing Emerging
Pollutants - March 25, 2010, 2:00PM-3:30PM EDT (18:00-19:30 GMT). As of January
2006, there were more than 239,000 substances on the Chemical Abstracts Service list
of regulated chemicals. The production of more than 4,800 of these chemicals
exceeded 1,000 metric ton/year. This total does not include the massive quantities of
"naturally occurring" contaminants that may enter the human environment due to
resource extraction and production such as mining, groundwater pumping and
agricultural practices. That said, how is it possible to identify those contaminants of
most environmental concern, and then winnow that list further to those contaminants
most likely to be the foci of attention in future mega-contamination sites? In short, how
can we identify the contaminants most likely to create the next generation of Superfund
sites? Motivated by this challenge, a workshop of 24 experts was convened in August
2009 with the express purpose of answering this question. The participants were
specifically chosen to encompass the broad spectrum of disciplines with insight into the
issue's many different facets, including toxicology; pharmacokinetics; pharmacology;
risk assessment; contaminant fate and transport; chemical bioaccumulation,
bioavailability and persistence; chemical parameter estimation and modeling; analytic
chemistry; chemical production, use and disposal, and monitoring and assessment
technology. It is the intent of this seminar to summarize the discussions, conclusions,
and identification of challenges that have evolved (so far) out of the workshop. For

Conference Proceedings for International Perspectives on Environmental
Nanotechnology: Applications and Implications (EPA 905-R-09-032). This
conference was held October 7-9, 2008 in Chicago and was attended by almost 200
scientists and engineers from 5 continents. Attendees were from governments,
universities, non-government organizations, and the private sector. One of the primary
goals for the conference was to assemble people from around the world who are
working on the broad swath of environmental nanotechnology applications and
implications, in order to advance the robust and prudent multidisciplinary approach
needed for this new area.Volume 1 covers environmental applications (remediation,
sensing & monitoring, and pollution control) of nanotechnology whereas volume 2
covers implications (toxicity, fate & transport, and risk assessment) of the release of
nanomaterials into the environment. The proceedings contain papers based on the
presentations provided during the conference and written by the presenting authors.
Thus, this treatise presents cutting edge environmental nanotechnology research and
development and should serve as a reference on the topic for years to come (November

2009, 611 pages). View or download at http://www.epa.aov/osp/hstl/stlworkshops.htm .

Technology Performance Review: Selecting and Using Solidification/Stabilization
Treatment for Site Remediation (EPA 600-R-09-148). Solidification/Stabilization (S/S)
is a widely used treatment technology to prevent migration and exposure of
contaminants from a contaminated media (i.e. soil, sludge and sediment). Solidification
refers to a process that binds a contaminated media with a reagent changing its
physical properties. Stabilization refers to the process that involves a chemical reaction
that reduces the leachability of a waste. S/S treatment and application is primarily used
at hazardous waste sites. This Technology Performance Review (TPR) includes a
discussion on several sites, and addresses important factors to consider in the
selection of S/S treatment. Each S/S case study has a brief project description,
regulatory status, S/S treatment process that includes binder materials used, and a
summary of the performance data. Estimated treatment costs and maintenance
activities are also included when available. Estimated costs must be adjusted for

Technology News and Trends (EPA 542-N-10-001). This issue highlights the use of

compound specific isotope analysis (CSIA), an environmental forensics technique used
to characterize contaminated sites and the progress of bioremediation and natural
attenuation. CSIA measures and compares the ratios of stable isotopes found in
compounds of suspected contaminant sources or plumes as well as the feedstock or
manufacturing process of materials historically used in a site's vicinity. Isotopic analysis
can help discern the potential for multiple spills of the same compound based on their
different isotopic "signatures." An isotopic signature can be used to associate a
contaminant plume with a particular spill or potentially responsible party. It also can be
used to evaluate the extent of contaminant degradation caused by microbes during
natural attenuation (February 2010, 6 pages). View or download at http://ciu-in.ora/techpubs.htm
