Open Solicitation  
ESTCP Solicitation!!  The DoD Environmental Security  
Technology Certification Program (ESTCP) is seeking innovative  
environmental technology demonstrations as candidates for  
funding beginning in Fiscal Year (FY) 2008.  This solicitation was  
released on January 4, 2007.   It requests pre-proposals via Calls  
for Proposals to Department of Defense (DoD) organizations and  
Federal (Non-DoD) organizations, and via a Broad Agency  
Announcement for Private Sector organizations.  The DoD Call for  
Proposals requests pre-proposals related to each of the ESTCP  
focus areas: (1) Environmental Restoration; (2) Munitions  
Management; (3) Sustainable Infrastructure; and (4) Weapons  
Systems and Platforms.  Note that descriptions of these Topic  
Areas are included in Appendix A of the DoD Instructions.  The  
Non-DoD Federal Call for Proposals and the Broad Agency  
Announcement requests pre-proposals in the following topics only:  
(1) Military Munitions Detection, Discrimination, and  
Remediation; (2) Sustaining Natural Resources on Training and  
Testing Lands; (3) Remediation of Contaminated Groundwater; (4)  
Remediation of Contaminated Sediments; and (5) Energy  
Efficiency and Renewable Energy for DoD Installations.  Note that  
descriptions of these Topic Areas are included in Appendix A of  
the instructions for both the Federal (Non-DoD) organizations and  
for Private Sector organizations.  The due date for all pre-proposals  
is March 15, 2007.  For more information, see .  
Upcoming Live Internet Seminars  
ITRC An Overview of Direct-push Well Technology for Long-  
term Groundwater Monitoring - February 6. Direct-push wells  
have been used for temporary groundwater monitoring purposes  
for many years but are generally prohibited for use as long-term  
groundwater monitoring wells. Recent research indicates that  
direct-push wells are as well suited for long-term environmental  
groundwater monitoring purposes as conventionally constructed  
wells. This training introduces ITRC's The Use of Direct-push  
Well Technology for Long-term Environmental Monitoring in  
Groundwater Investigations (SCM-2, 2006), provides a  
background in the principles of direct-push wells, and presents the  
state of the art regarding recent research. For more information and  
to register, see or .  
ITRC Characterization, Design, Construction and Monitoring of  
Bioreactor Landfills - February 8. Bioreactors are landfills where  
controlled addition of non-hazardous liquid wastes, sludges, or  
water accelerates the decomposition of waste and landfill gas  
generation. This training, based on the ITRC's Characterization,  
Design, Construction, and Monitoring of Bioreactor Landfills  
(ALT-3, 2006), teaches the principles used to make critical  
decisions during permitting, operating, and monitoring a bioreactor  
landfill. This training also provides a general understanding of the  
biological degradation of solid wastes under aerobic and anaerobic  
waste conditions and the degradation products associated with each  
process. For more information and to register, see or .  
Nanotechnology - Metals Remediation - February 13. The  
Superfund Basic Research Program (SBRP), in collaboration with  
the Environmental Protection Agency (EPA), presents  
'Nanotechnology - Metal Remediation' the 2nd session of the  
2007 edition of Risk-e-Learning 'Nanotechnology: Applications  
and Implications for Superfund.' This session will highlight the  
potential of nanotechnology-based approaches to remove metals  
from drinking water. Dr. Mason Tomson, Professor of Chemical  
and Environmental Engineering (Rice University, Houston, TX)  
will introduce the use of nano-magnetite to remove arsenic from  
drinking water.  Nano-magnetite has been found to be a good  
adsorbent for arsenate and arsenite.  Dr. Tomson overviews results  
from research at the Center for Biological and Environmental  
Nanotechnology in collaboration with Drs. Vicki Colvin and Paul  
Laibinis. In addition, Dr. Shas Mattigod, Senior Research Scientist  
(Pacific Northwest National Laboratory, Richland, WA), will  
introduce his research using functionalized nanoporous ceramic  
sorbents for removal of mercury and other contaminants.  This talk  
overviews the synthesis of self-assembled monolayers on  
mesoporous silica (SAMMS) and describes how functionalized  
surface chemistry can be used for adsorption of particular metal  
species of mercury, chromium and arsenic.  Dr. Mattigod will  
cover treatment costs, waste form stability, and potential  
applications and commercialization of this approach. For more  
information and to register, see .  
ITRC Evaluating, Optimizing, or Ending Post-Closure Care at  
Municipal Solid Waste Landfills - February 15. This training,  
based on ITRC's Technical and Regulatory Guidance: Evaluating,  
Optimizing, or Ending Post-Closure Care at Municipal Solid  
Waste Landfills Based on Site-Specific Data Evaluations (ALT-4,  
2006), describes a method to evaluate the performance of Post  
Closure Care at a landfill and determine when leachate recovery,  
landfill gas management, groundwater monitoring, and cap  
maintenance can be reduced or even ended based on threats (to  
human health and the environment) posed by the closed landfill.  
The training and document describe custodial care as those  
requirements the property owner must follow after post closure  
care has been ended. For more information and to register, see or .  
Innovative Air Monitoring at Landfills Using Optical Remote  
Sensing with Radial Plume Mapping - February 22. Landfill gas  
(LFG) emissions can be a large contributor to local air problems;  
and they are the largest source of methane emissions in the United  
States. EPA researchers will show how Optical Remote Sensing  
(ORS) and Radial Plume Mapping (RPM) can be used together to  
characterize LFG emissions, by using the example of ORS and  
RPM in action at a landfill demonstration in North Carolina. In  
addition to the lessons learned at this and other demonstration  
sites, this work has produced several research articles, a general  
method for characterization of emissions from non-point sources  
(OTM-10), and EPA guidance for evaluating LFG at closed and  
abandoned landfills. For more information and to register, see .  
ITRC Planning and Promoting of Ecological Land Reuse of  
Remediated Sites - February 27. This training is based on the ITRC  
Technical and Regulatory Guideline: Planning and Promoting  
Ecological Land Reuse of Remediated Sites (ECO-2, 2006). The  
document presents a process to promote ecological land reuse  
activities considering natural or green technologies instead of more  
traditional remedies. The guidance demonstrates that natural or  
ecological end-uses are valuable alternatives to conventional
