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 31st. For more information, please

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 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

Energy for the Future: Exploring Methane Gas-to-Energy Projects  
at Superfund 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 webinar will 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.

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,

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 information and to register,

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  
contaminated media while ex situ processes transfer the media  
for treatment at or near ground surface (March 2010, 4 pages).
