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.

Upcoming Live Internet Seminars  
Your Role in Green Remediation Implementation and Case Studies  
in Green Remediation - This Year's Models and Tools (The 2010  
NARPM Green Remediation Session Follow-on Webinars) - January 11  
and February 10. In May 2010, EPA held its annual National  
Association of Remedial Project Managers (NARPM) meeting in  
Crystal City, VA, and for the third year in a row, one of our  
most attended sessions was on Green Remediation (GR). And like  
last year, we are offering those talks again to an online  
audience! EPA's definition of GR includes the practice of  
considering the environmental effects of a remediation strategy  
(i.e., the remedy selected and the implementation approach)  
early in the process, and incorporating options to maximize the  
net environmental benefit of the cleanup action. We've got more  
case studies and maturing policy and guidance that we'd like to  
share with an online audience. EPA's Technical Support Project,  
led by the Engineering Forum, has taken this full-day session  
and split it into three separate sessions that started in  
December. Each session is scheduled for two hours and will  
include policy and case studies, with time for Q&A along the  
way. For more information and to register for the two remaining  
sessions, see  
ITRC Use and Measurement of Mass Flux and Mass Discharge -  
January 13, 2011, 11:00AM-1:15PM EST (16:00-18:15 GMT). The ITRC  
technology overview, Use and Measurement of Mass Flux and Mass  
Discharge (MASSFLUX-1, 2010), and associated Internet-based  
training provide a description of the underlying concepts,  
potential applications, description of methods for measuring and  
calculating, and case studies of the uses of mass flux and mass  
discharge. This Technology Overview, and associated  
Internet-based training are intended to foster the appropriate  
understanding and application of mass flux and mass discharge  
estimates, and provide examples of use and analysis. The  
document and training assumes the participant has a general  
understanding of hydrogeology, the movement of chemicals in  
porous media, remediation technologies, and the overall remedial  
process. For more information and to register, see or .  
Contaminated Sediments: New Tools and Approaches for in-situ  
Remediation - Session III - January 19, 2011, 2:00PM-4:00PM EST  
(19:00-21:00 GMT). This seminar will feature SRP grantees Dr.  
Richard G. Luthy and Dr. Charles A. Menzie. Dr. Luthy of the  
Woods Institute for the Environment at Stanford University will  
review recent experimental studies and modeling work that  
describe the up-take of hydrophobic organic contaminants by  
activated carbon amendment in sediment. The emphasis will be on  
practical aspects of testing and modeling to assess the  
suitability of sediment for in-place treatment of persistent  
organic contaminants by activated carbon sorbent. A comparison  
of different feeding traits of benthic organisms illustrates the  
degree of treatment needed to achieve a desired remedial success  
of sorbent amendment. Recent work with polysulfide  
rubber-modified activated carbon suggesting the potential to  
treat both mercury and hydrophobic organic compounds will also  
be presented. A follow-up by Dr. Charles Menzie of Exponent Inc.  
will discuss the efficacy of various methods of application of  
SediMite, a pelletized agglomerate that consists of activated  
carbon, to contaminated sediments. He will focus on the  
effectiveness of delivery methods designed to minimally disturb  
sediment, yet deliver activated carbon amendment to the depth  
inhabited by biota. For more information and to register, see .  
ITRC Use of Risk Assessment in Management of Contaminated Sites  
- January 25, 2011, 2:00PM-4:15PM EST (19:00-21:15 GMT). This  
training course identifies how various risk-based approaches and  
criteria are applied throughout the processes of screening,  
characterization, and management of contaminated sites. The  
training course and associated overview document, Use of Risk  
Assessment in Management of Contaminated Sites (RISK-2, 2008),  
are intended for risk assessors and project managers involved  
with the characterization, remediation, and/or re-use of sites.  
The training and overview document provide a valuable tool for  
federal and state regulatory agencies to demonstrate how site  
data collection, risk assessment, and risk management may be  
better integrated. For more information and to register, see or .  
ITRC Phytotechnologies - January 27, 2011, 11:00AM-1:15PM EST  
(16:00-18:15 GMT). This training familiarizes participants with  
ITRC's Phytotechnology Technical and Regulatory Guidance and  
Decision Trees, Revised (Phyto-3, 2009). This document provides  
guidance for regulators who evaluate and make informed decisions  
on phytotechnology work plans and practitioners who have to  
evaluate any number of remedial alternatives at a given site.  
This document updates and replaces Phytoremediation Decision  
Tree (Phyto-1, 1999) and Phytotechnology Technical and  
Regulatory Guidance Document (Phyto-2, 2001). It has merged the  
concepts of both documents into a single document. This guidance  
includes new, and more importantly, practical information on the  
process and protocol for selecting and applying various  
phytotechnologies as remedial alternatives. For more information  
and to register, see or .  
New Documents and Web Resources  
Best Management Practices: Use of Systematic Project Planning  
Under a Triad Approach for Site Assessment and Cleanup (EPA  
542-F-10-010). This technical publication is intended for  
environmental practitioners engaged in the investigation,  
design, remediation, and closure or reuse of contaminated sites.  
Systematic Project Planning is a rigorous project planning  
process that lays a scientifically defensible foundation for  
proposed project activities. The bulletin discusses important  
considerations and contingencies that need to be addressed, and  
key activities to be performed during SPP at hazardous-waste  
sites. It guides the reader to think about SPP from early  
assessment, to evolving to a mature conceptual site model, to  
looking ahead at site re-use; and emphasizes up-front effort.  
Included are references where the reader can find tools and more  
detailed technical guidance (September 2010, 19 pages). View or

Technology News and Trends (EPA 542-N-10-006). This issue  
highlights pilot-scale and demonstration projects to  
characterize and remediate sites with fractured bedrock  
contaminated by volatile organic compounds. Technologies applied  
in these projects involve subsurface injection of reactive  
amendments, in situ thermal conductive heating systems,
