Open Solicitation  
EPA National Student Design Competition for Sustainability.  
The US Environmental Protection Agency's 2006 P3 (People,  
Prosperity and the Planet) competition opened December 12, 2005.  
This grant program advances a sustainable future by fostering the  
next generation of scientists, engineers, and technology workers.  
For the 2006 competition, up to 50 teams will receive initial grants  
of up to $10,000 to develop their designs.  The program awards  
grants to teams of undergraduate and graduate students, along with  
their faculty advisors, to design and develop innovative  
technologies and other sustainability projects, and in the process  
integrate sustainability issues into higher education curricula.  Each  
May, teams present their projects on the National Mall in  
Washington, DC for a chance to win additional funding to move  
their ideas from the design phase to the marketplace.  The awards  
competition is judged by a panel of experts convened by the  
National Academies, advisors to the nation on science,  
engineering, and medicine.  The deadline for submission is  
February 20, 2006.  For more information, see  
Internet Seminars  
ITRC What's New with In Situ Chemical Oxidation? - January  
10.   This seminar presents updated guidance and technology  
advancement information for In Situ Chemical Oxidation. Topics  
include a regulatory discussion related to ISCO implementation;  
details on the chemistry behind ISCO technology; considerations  
for system design and application, including health and safety; and  
performance evaluation information. The course is based on the  
ITRC's In Situ Chemical Oxidation of Contaminated Soil and  
Groundwater, Second Edition (ISCO-2, 2005), with sections on  
technology overview and applicability, remedial investigations,  
safety concerns, regulatory concerns, injection design, monitoring,  
stakeholder concerns, and case studies.  For more information and  
to register, see or .  
ITRC What is Remediation Process Optimization And How  
Can It Help Me Identify Opportunities for Enhanced and  
More Efficient Site Remediation? - January 12.  This training  
discusses the value of optimization in efficiently and objectively  
setting and attaining remediation goals.  Key elements of RPO that  
will be discussed in the training include:  Appropriate use of  
up-to-date conceptual site models (CSM); Flexible Remedial  
Action (RA) operations considering technology limitations and risk  
assessments; use of treatment trains for each target zone, and  
developing performance objectives for each element; development  
of an exit strategy for each remedy component considering  
life-cycle factors; and life-cycle cost analysis as a decision-making  
tool with the requirement that protectiveness must be maintained or  
improved.  For more information and to register, see or .  
ITRC Permeable Reactive Barriers: Lessons Learned and New  
Directions - January 24.   This training presents updated  
information regarding new developments, innovative approaches,  
and lessons learned in the application of PRBs to treat a variety of  
groundwater contaminants. The information will be presented by  
reviewing the approaches and results at several sites where PRBs  
have been deployed.  The training is based on the ITRC guidance  
document titled Permeable Reactive Barriers: Lessons Learned /  
New Directions (PRB-4, 2005).  For more information and to  
register, see  or  
Revegetation and Restoration of an Oil Contaminated Wetland  
in Northern New Jersey - January 19.  This presentation will  
attempt to show that a carefully supervised cleanup followed by a  
scientifically driven monitoring program can be effective in  
removing oil from a sensitive wetland habitat using the Green  
Pond Oil Spill Removal project as the prime example.   A  
monitoring program for determining the success of the  
revegetation/restoration effort was conducted.  Species  
composition and productivity measurements were an integral part  
of the parameters to measure the progress of the effort to determine  
comparability between the remediated site and undisturbed  
wetlands.  The presentation will incorporate all that has been  
learned from the removal activity in terms of How Clean is Clean  
as applied to an oil contaminated fresh water wetland. This  
information should be useful for decision makers, responders, and  
consultants alike when faced with remediating disturbed or  
contaminated habitats.  For more information and to register, see .  
NIEHS DNAPLs - Biological Remediation Processes - January  
25.  This seminar is the fourth in a series sponsored by the NIEHS  
Superfund Basic Research Program to present current research on  
DNAPLs contaminated sites. The seminar will summarize a  
comprehensive literature review on the microbial degradation of  
chlorinated solvents.  Chlorinated solvents such as chlorinated  
ethenes, ethanes and methanes are important priority pollutants of  
groundwater.  Diverse strategies are utilized by microorganisms in  
the degradation of organochlorine compounds ranging from  
reductive dehalogenation, hydrolytic to oxygenolytic release of  
chloride.  To understand how microorganisms gain energy and  
benefit from biodegradation of chlorinated solvents, one must  
consider biodegradation as a redox reaction in which an electron  
donor becomes oxidized at the expense of an electron acceptor.   In  
addition to the discussion of bioremediation processes, the session  
will also discuss advances in phytoremediation techniques for  
important toxicants at hazardous waste sites.   For more information  
and to register, see .  
ITRC Environmental Management Planning on Active Small  
Arms Firing Ranges - January 26.  The training uses a logic  
diagram to describe the appropriate steps an environmental  
professional or range manager should use to establish an  
operational understanding of a range and the impact it can have on  
the environment if left unattended.   It assists the user to define the  
environmental characteristics at a range that could potentially  
impact the environment and lists the appropriate questions that  
range operators should ask when evaluating the potential for  
environmental impact.  The training briefly describes a variety of  
new and conventional technologies and techniques (i.e., best  
management practices) available to prevent environmental impact  
on the range.  For more information and to register, see or .
