ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation -
December 6, 2011, 2:00PM-4:15PM EST (19:00-21:15 GMT). This training, which is
based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and
Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and
conventional fuels specific to release scenarios, environmental impacts,
characterization, and remediation. The trainers will define the scope of the potential
environmental challenges by introducing biofuel fundamentals, regulatory status, and
future usage projections. Participants will learn how and when to use the ITRC biofuels
guidance document for their projects. They will understand the differences in biofuel
and petroleum behavior; become familiar with the biofuel supply chain, potential
release scenarios and release prevention; be able to develop an appropriate
conceptual model for the investigation and remediation of biofuels; and select
appropriate investigation and remediation strategies. For more information and to

ITRC LNAPL Training Parts 1, 2, and 3 - December 8,13,15, 2011. 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

Updated CLU-IN In Situ Oxidation Focus Area. In situ chemical oxidation, also
referred to as ISCO, is an aggressive remediation technology that has been applied to a
wide range of volatile and semivolatile hazardous contaminants, including DNAPL
source zones and the dissolved-phase chemicals emanating from the source zones.

The 2010 Superfund Remedy Report (Thirteenth Edition) reports that ISCO was
selected as a remedy at 36 Superfund sites during the period 2005 to 2008. Chemical
oxidation typically involves reduction/oxidation (redox) reactions that chemically convert
hazardous compounds to nonhazardous or less toxic compounds that are more stable,
less mobile, or inert. Redox reactions involve the transfer of electrons from one
compound to another. Specifically, one reactant is oxidized (loses electrons) and one is
reduced (gains electrons). The oxidizing agents most commonly used for treatment of
hazardous contaminants in soil and groundwater are hydrogen peroxide, catalyzed
hydrogen peroxide, potassium permanganate, sodium permanganate, sodium
persulfate, and ozone. Each oxidant has advantages and limitations, and while
applicable to soil contamination and some source zone contamination, they have been
applied primarily toward remediating groundwater. View and use at http://ciu-in.ora/isco .

Nanotechnology: Applications for Environmental Remediation CLUIN
Technology Focus Area Fact Sheet. This fact sheet describes a new remediation
technology focus area: Nanotechnology: Applications for Environmental Remediation.
The goal of this focus area is to help site owners and other parties involved in remedial
activities understand the current and potential applications of nanotechnology at their
sites. Information on this website is organized into the following categories: Overview,
Guidance, Application, Training, and Additional Resources. View or download at

Electronic Data Deliverables: The Importance of Receiving Your Site and Project
Data Electronically (EPA 542-F-11-010). The purpose of this fact sheet is to
encourage even wider use of Electronic Data Deliverables (EDDs) by explaining their
importance and how to ensure that your site data are submitted electronically. The EDD
Fact Sheet Appendix provides supplemental information on what to request in EDDs,
how electronic data are shared, examples of data to submit electronically, and links to
EDD guidance (April 2011, 2 pages). View or download at http://ciu-in.ora/techpubs.htm .

Final Report: Applied Materials Building 1: Long-Term Monitoring Strategy (EPA
542-R-11-006). A five-year review documenting the progress of Applied Materials
Building 1 (AM1) toward remedial goals was completed in 2010. The site has largely
achieved remedial goals for groundwater; however, specific National Priorities List
(NPL) close-out prospects for sites with rare or intermittent exceedances of
groundwater cleanup goals over a limited spatial extent are not clear. Additionally, the
presence of groundwater plumes on adjacent properties may complicate the close-out
decision. This memorandum reviews historical site data and how they might support the
development of a long-term, close-out strategy for the AM1 site. Statistical analyses
were performed using modules within the Monitoring and Remediation Optimization
System software (MAROS) and ProUCL software (October 2011, 45 pages). View or

Integrated DNAPL Site Strategy: Technical/Regulatory Guidance. To help
managers develop successful integrated strategies for chlorinated solvent sites, this
document describes key concepts and recent developments in each of five areas: (1) a
conceptual site model based on reliable characterization methods and an
understanding of the subsurface conditions that control contaminant transport,
reactivity, and distribution; (2) remedial objectives and performance metrics that are
clear, concise, and measurable; (3) treatment technologies applied in sequence or in
parallel designed to optimize performance and take advantage of potential synergistic
effects; (4) monitoring strategies based on interim and final cleanup objectives, the
selected treatment technology and approach, and remedial performance goals; and (5)
re-evaluating the strategy repeatedly and modifying the approach when objectives are
not being met or when alternative methods offer similar or better outcomes at lower
cost (November 2011, 209 pages). View or download at

Technology News and Trends (EPA 542-N-11-005). This issue highlights cleanup
approaches that rely on waste materials or treatment processes as a means to
generate heat or other forms of energy for onsite or offsite use. Energy-generating
sources can include extracted groundwater already warmed by subsurface
temperatures, landfill gas with a high methane content, and soil containing byproducts
from coal mining or processing. Recovery of these potential energy sources can help
beneficially reuse materials or media that are traditionally treated or discarded as waste
and may defray cleanup costs. (November 2011, 6 pages). View or download at
