Upcoming Live Internet Seminars  
A Systematic Approach for Evaluation of Capture Zones at Pump   
and Treat Systems - October 8. This seminar presents a   
systematic approach for the evaluation of capture zones at pump   
and treat systems, and provides an overview of a recently   
published USEPA document on the topic (EPA 600/R-08/003, January   
2008). The target audience is project managers who review those   
analyses and/or make decisions based on these types of analyses.   
This course will highlight: the importance of capture zone   
analysis during ground water remediation, particularly for sites   
requiring containment; key concepts of capture, such as 'target   
capture zones' and 'converging lines of evidence;' and typical   
errors made in capture zone analysis. Examples will be used to   
demonstrate key aspects of capture zone analysis. For more   
information and to register, see .  
ITRC Perchlorate Remediation Technologies - October 9. This   
training introduces state regulators, environmental consultants,   
site owners, and community stakeholders to Remediation   
Technologies for Perchlorate Contamination in Water and Soil   
(PERC-2, 2008), created by ITRC's Perchlorate Team to assist   
reviewers in assessing the adequacy of perchlorate remediation   
projects. This course gives the student a background in the   
available remediation technologies to treat perchlorate   
contamination, discusses emerging technologies, and presents   
case studies of applications. For more information and to   
register, see or   
Phytoremediation - October 14. The Superfund Basic Research   
Program (SBRP), in collaboration with the Environmental   
Protection Agency (EPA) Office of Superfund Remediation and   
Technology Innovation (OSRTI) presents 'Phytoremediation.' This   
series of online seminars will focus on the science of   
incorporating phytoremediation into hazardous waste site   
remediation plans. Dr. David Tsao, BP Corporation North America,   
Inc., will provide an overview of phytotechnologies, a broad set   
of technologies that utilize plant-derived processes to   
remediate or contain contaminants in soil, sediments, surface,   
or groundwater. Dr. Tsao will also touch on the limitations that   
need to be considered when evaluating the use of   
phytotechnologies for site-specific applications. Dr. Jerald   
Schnoor, SBRP-University of Iowa, will focus on plant   
degradation of airborne PCB congeners, a potential in situ   
treatment PCBs in soils and groundwater. Dr. Schnoor will   
describe the green liver model, which explains the fate of   
organic contaminants inside plant tissues, and will focus on the   
three phases of PCB metabolism. He will also introduce poplar   
experiments designed to confirm which genes are responsible for   
PCB metabolism as well as studies that identify endophytic   
bacteria and rhizosphere microorganisms that increase the rate   
of PCB degradation. For more information and to register, see .  
ITRC Protocol for Use of Five Passive Samplers - October 16.   
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, see or .  
The Brownfields Assessment, RLF and Cleanup Grant Proposal  
Guidelines: A National Q&A Session - October 16. The proposal   
deadline for the Environmental Protection Agency's Brownfields   
Assessment, RLF and Cleanup Grants is quickly approaching. This   
National outreach session will review the evaluation criteria   
and selection process for the grants, but will dedicate most of   
the time to Questions and Answers from applicants. EPA   
encourages participants to think of questions they have ahead of   
time and come prepared to contribute to the discussion. For more   
information and to register, see .  
ITRC Real-Time Measurement of Radionuclides in Soil - October   
28. 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 .  
Green Remediation: Opening the Door to Field Use Session A   
(Introduction and Carbon Calculus: A RCRA Case Study) - November   
24. In July, EPA held its annual National Association of   
Remedial Project Managers meeting in Portland, OR and one of our   
most attended sessions was on Green Remediation (GR). Because   
of its success, members of EPA's Technical Support Project, led   
by the Engineering Forum, have taken this full-day session and   
are bringing back a number of the same talks as online seminars   
this fall and winter. There will be three sessions, each 1.5   
hours long. 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. Some practices   
are quite 'mature,' such as construction site best management   
practices including stormwater runoff management and   
construction and demolition (C&D) debris recycling. Others are   
still emerging, including the use of renewable energy sources   
such as wind and solar to power remedial systems. Over the   
three sessions, the online training will introduce you to the   
key technical, policy, and application aspects of GR. For more

New Documents and Web Resources  
Hazardous Waste Clean-Up Information (CLU-IN) On-line   
Remediation Databases Fact Sheet (EPA 542-F-06-006). The U.S.   
EPA Office of Superfund Remediation and Technology Innovation,   
Technology Innovation and Field Services Division sponsors eight   
on-line remediation project profile databases, including five   
technology-specific databases - Alternative Landfill Covers, In   
Situ Thermal Treatment, In Situ Chemical Oxidation, In Situ   
Flushing, and Phytotechnology; on
