US EPA Tech Direct March 1st
Welcome to TechDirect! March signals the beginning our our 13th   
year delivering TechDirect. We have been very pleased (and   
somewhat surprised) at the continued and steady growth of our   
subscribers over the last 12 years. Since the February 1   
message, TechDirect gained 224 new subscribers for a total of   
30,252. If you feel the service is valuable, please share   
TechDirect with your colleagues. Anyone interested in   
subscribing may do so on CLU-IN at . All   
previous issues of TechDirect are archived there. The TechDirect   
messages of the past can be searched by keyword or can be viewed   
as individual issues.  
TechDirect's purpose is to identify new technical, policy and   
guidance resources related to the assessment and remediation of   
contaminated soil, sediments and ground water.  
Mention of non-EPA documents or presentations does not   
constitute a U.S. EPA endorsement of their contents, only an   
acknowledgment that they exist and may be relevant to the   
TechDirect audience.  
Upcoming Live Internet Seminars  
ITRC Real-Time Measurement of Radionuclides in Soil - March 13.   
This training introduces state regulators, environmental   
consultants, site owners, and community stakeholders to ITRC's   
Technology Overview document: Real-Time Measurement of   
Radionuclides in Soil: Technology and Case Studies (RAD-4,   
2006), created by ITRC's Radionuclides Team. This training   
provides information on the basics of real-time measurement   
systems, how the technologies and data are used, acceptance   
issues, and case studies. For more information and to register,   
see or .  
ITRC Evaluating, Optimizing, or Ending Post-Closure Care at   
Municipal Solid Waste Landfills - March 18. 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 .  
ITRC Survey of Munitions Response Technologies - March 25. This   
training introduces Survey of Munitions Response Technologies   
(UXO-4, 2006), created by the ITRC's Unexploded Ordinance Team   
in partnership with the Strategic Environmental Research and   
Development Program (SERDP) and the Environmental Security   
Technology Certification Program (ESTCP). The document provides   
an overview of the current status of commercially-available   
technologies in common usage for munitions response actions,   
and, where possible, assess and quantify their performance   
capabilities. This training course is intended for an   
intermediate to advanced audience and assumes an understanding   
of technologies and phases of munitions response. This training   
course focuses on the major take-home conclusions of the Survey   
of Munitions Response Technologies (UXO-4, 2006) and provides an   
understanding of the performance capabilities of available   
technologies under real-world site conditions. For more   
information and to register, see or .  
ITRC Decontamination and Decommissioning of   
Radiologically-Contaminated Facilities - April 3. This training   
introduces ITRC's Technical/Regulatory Guidance, Decontamination   
and Decommissioning of Radiologically-Contaminated Facilities   
(RAD-5, 2008), created by ITRC's Radionuclides Team. The   
curriculum is composed of four modules: Introduction and   
Regulatory Basis for Decontamination and Decommissioning (D&D),   
Factors for Implementing D&D, Preliminary Remediation Goal (PRG)   
Calculators, and Case Studies and Lessons Learned. For more   
information and to register, see or .  
New Documents and Web Resources  
Green Remediation Website. EPA's Office of Superfund Remediation   
and Technology Innovation has released a Green Remediation web   
site. The site explains the basic principles and objectives of   
green remediation, and outlines best practices for reducing the   
environmental footprint of contaminated site cleanup projects.   
Over coming months, the site will expand to describe more   
details on green remediation best practices, and serve as a   
clearinghouse for technical materials, decision-making tools,   
site-specific case studies illustrating green remediation   
implementation efforts, and information on green remediation   
related events and new information products. View and use at .  
Proceedings of the Nanotechnology for Site Remediation Workshop,   
Chicago, September 6-7, 2006 (EPA 905-K-07-001). In October   
2004, the US EPA held a nanotechnology site remediation   
conference, with assistance from partner federal agency   
cosponsors. The 2004 conference was followed in 2006 with a   
2-day national site remediation workshop, jointly sponsored by   
the EPA Region 5 (R5) and the EPA Office of Research and   
Development (ORD). This workshop is the subject of these   
Proceedings and targeted Superfund remedial project managers   
(RPMs) at the R5 offices in Chicago, Illinois. The workshop was   
attended by close to 100 participants. During the first day, the   
workshop focused on nanomaterials applications to remediate   
hazardous waste sites, whereas during the second day, the focus   
was on environmental implications of nanomaterials (December   
2007, 51 pages). View or download at ... .  
Proceedings of the Desert Remedial Action Technologies (D-RAT)   
Workshop, Phoenix, October 2007. This workshop was sponsored by   
the US EPA and the Arizona Department of Environmental Quality.   
Desert environments in the southwestern United States and   
similar areas present a number of unique challenges to   
subsurface cleanup. Groundwater can be extremely deep and the   
presence of clays and fractured rock can reduce the   
effectiveness of some standard cleanup technologies. The goal of   
the workshop was to gather practitioners and others with   
remediation expertise in these desert environments and to   
present both lecture and poster presentations on their ideas for   
remediating soil and groundwater. The scope of the workshop was   
limited to sites with VOCs, perchlorate and chromium, as these   
contaminants present some of the greatest challenges for cleanup   
(December 2007, 27 pages). View or download at ...

Ground Water Issue Paper: Metal Attenuation Processes at Mining   
Sites (EPA 600-R-07-092). This report was published by the U.S.   
EPA Ground Water Forum and the National Risk Management Research   
Laboratory. The purpose of this Issue Paper is to provide   
scientists and engineers responsible for assessing remediation   
technologies with background information on MNA processes at   
mining-impacted sites. Some of the key issues concerning the   
application of natural attenuation for inorganic contaminants   
are discussed, such as the geochemical mechanisms responsible   
for attenuation, attenuation capacity, monitoring parameters,   
and evaluating whether attenuated metal and metalloid   
contaminants will remain immobile (October 2007, 13 pages). View
