> NICOLE Technology Award

Call for 2010 Entries on Innovative Site Characterization. Over the last 10 years,
NICOLE has carried out multiple projects and organized a series of workshops,
providing a discussion platform and a sound technical basis for risk based management
of contaminated land. Reoccurring themes in the discussions on risk-based land
management are sustainability and cost-efficiency.This year, the NICOLE Steering
Group decided to launch a yearly technology award. This award intends to stimulate
people to bring forward technical innovations that can contribute to an improved
practice for contaminated land management in line with the NICOLE ambition. For
2010, entries are invited that focus on "Innovative site characterization tools". The
award is open to individuals or groups of people. Entries from junior academics in
universities or consultancy are especially welcome. Entries will be judged on
innovation, potential contribution to cost savings, technical applicability and plans for
communication and market availability. The Year 2010 deadline is October 31 st. For

ITRC LNAPL Training Parts 1, 2, and 3 - May 6,13, and 20, 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

Energy for the Future: Exploring Methane Gas-to-Energy Projects atSuperfund
Sites - May 6, 2010, 2:00 PM-4:00 PM, EDT (18:00-20:00 GMT). An increasing
number of landfills across the country are being put to use as alternative energy power
sources. Currently, EPA tracks over 15 National Priorities List (NPL) Superfund sites
supporting methane gas-to-energy projects. Methane energy released from these
landfills is captured to produce power for local utilities and nearby facilities. The
Superfund Redevelopment Initiative's May webinarwill explore reusing Superfund sites
for this innovative purpose by inviting stakeholders involved in a variety of methane
gas-to-energy projects to share their perspectives. Representatives from Waste
Management's renewable energy group will present on their Superfund landfill projects,
and EPA staff will discuss the Office of Superfund Remediation and Technology
Innovation's (OSRTI) project to implement cost-effective gas-to-energy projects at
approximately 8 NPL landfills. Site stakeholders from Superfund projects currently
underway will also share key lessons, challenges and impacts from projects at their
sites. For more information and to register, see http://ciu-in.ora/iive .

ITRC Protocol for Use of Five Passive Samplers - May 18, 2010, 2:00PM-4:15PM
EDT (18:00-20:15 GMT). This training supports the understanding and use of the ITRC
Protocol for Use of Five Passive Samplers to Sample for a Variety of Contaminants in
Groundwater (DSP-5, 2007). The five technologies included in this document include
diffusion samplers, equilibrated grab samplers, and an accumulation sampler. The
training starts with information common to all five samples then focuses on each
sampler as instructors describe the sampler and explain how it works; discuss
deployment and retrieval of the sampler; highlight advantages and limitations; and
present results of data comparison studies. For more information and to register, see

ECOS and USEPA Using the Toxics Release Inventory (TRI) to Support
Environmental Justice - May 25, 2010,1:00PM-3:00PM EDT (17:00-19:15 GMT).

The Environmental Council of the States (ECOS) and United States Environmental
Protection Agency (U.S. EPA) invite you to attend the 2010 TRI Webinar: Using TRI to
Support Environmental Justice. The purpose of the Webinar is to share experiences
and lessons learned using TRI to address environmental justice concerns and expand
TRI use among current and potential users who work on environmental justice issues.
Speakers will include representatives from U.S. EPA headquarters and regions,
non-profit organizations, and academia. All are welcome to participate! For more

Green Remediation Best Management Practices: Bioremediation (EPA
542-F-10-006).The EPA Principles for Greener Cleanups outlines the Agency's policy
for evaluating and minimizing the environmental "footprint" of activities undertaken
when cleaning up a contaminated site. Use of the best management practices (BMPs)
recommended in EPA's series of green remediation fact sheets can help project
managers and other stakeholders apply the principles on a routine basis, while
maintaining the cleanup objectives, ensuring protectiveness of a remedy, and improving
its environmental outcome. Bioremediation actively enhances the effects of naturally
occurring biological processes that degrade contaminants in soil, sediment, and
groundwater. In situ processes involve placement of amendments directly into

Green Remediation Best Management Practices: Soil Vapor Extraction & Air
Sparging (EPA 542-F-10-007). The EPA Principles for Greener Cleanups outlines the
Agency's policy for evaluating and minimizing the environmental "footprint" of activities
undertaken when cleaning up a contaminated site. Use of the BMPs recommended in
EPA's series of green remediation fact sheets can help project managers and other
stakeholders apply the principles on a routine basis, while maintaining the cleanup
objectives, ensuring protectiveness of a remedy, and improving its environmental
outcome. Historically, approximately one-quarter of Superfund source control projects
have involved soil vapor extraction (SVE) to remove volatile organic compounds
(VOCs) sorbed to soil in the unsaturated (vadose) zone. Air is extracted from, and
sometimes injected into, the vadose zone to strip VOCs from the soil and transport the
vapors to ex situ treatment systems for VOC destruction or recovery. Air sparging (AS)
involves injection of air into contaminated groundwater to drive volatile and semivolatile
contaminants into the overlying vadose zone through volatilization. SVE is commonly
implemented in conjunction with air sparging to remove the generated vapor-phase
contamination from the vadose zone (March 2010, 4 pages). View or download at

EPA Opens Access to Chemical Information through ToxRefDB. EPA is releasing
a database, called ToxRefDB, which allows scientists and the interested public to
search and download thousands of toxicity testing results on hundreds of chemicals.
ToxRefDB captures 30 years and $2 billion of testing results. ToxRefDB provides
detailed chemical toxicity data in an accessible format. It is a part of ACToR
(Aggregated Computational Toxicology Resource), an online data warehouse that
collects data from about 500 public sources on tens of thousands of environmentally
relevant chemicals, including several hundred in ToxRefDB. Those interested in
chemical toxicity can query a specific chemical and find all available public hazard,
exposure, and risk-assessment data, as well as previously unpublished studies related
to cancer, reproductive, and developmental toxicity. ToxRefDB contains toxicity
information that forms the basis for pesticide risk assessments when combined with
other sources of information, such as those on exposure and metabolism. View and

generated by conventional power plants. Highlighted projects include both large- and
small-scale systems producing power from wind, landfill gas, and solar resources (April
2010, 6 pages). View or download at http://ciu-in.ora/techpubs.htm .

Remediation of Organochlorine Pesticides in Soil. The California Department of
Toxic Substances Control has issued the third document in its proven technologies and

streamlines the cleanup process by limiting the number of evaluated technologies to
excavation/disposal and containment/capping. The guidance provides resources to
facilitate remedy design and implementation (February 2010, 110 pages). View or
