A Systematic Approach for Evaluation of Capture Zones at Pump and Treat
Systems - September 11 and 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 http://ciu-in.ora/studio .

ITRC Enhanced Attenuation of Chlorinated Organics: A Site Management Tool -
September 11. This training on the ITRC Technical and Regulatory Guidance for
Enhanced Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition
(the bridge) between aggressive remedial actions and MNA and vise versa. Enhanced
attenuation (EA) is the application of technologies that minimize energy input and are
sustainable in order to reduce contaminant loading and/or increase the attenuation
capacity of a contaminated plume to progress sites towards established remedial
objectives. Contaminant loading and attenuation capacity are fundamental to sound
decisions for remediation of groundwater contamination. This training explains how a
decision framework which, when followed, allows for a smooth transition between more
aggressive remedial technologies to sustainable remedial alternatives and eventually to
Monitored Natural Attenuation. This training will demonstrate how this decision
framework allows regulators and practitioners to integrate Enhanced Attenuation into
the remedial decision process. For more information and to register, see

LTM network design and implementation, then integration of sensors and logistics into
the development of the CSM, and will finally wrap up with examples of automated
monitoring (which includes contouring and model update). This workshop will cover
best-of-class approaches for CSM development with an emphasis on direct-push
technologies, then integrate new approaches to update this in the most
time/cost-effective manner. While the models are conceptual, the workshop will discuss
analytical components to the model to make quantification possible. For more
information and to register, see http://ciu-in.ora/studio .

Tree Coring to Assess Subsurface Volatile Organic Compounds - September 25.

Analysis of the volatile organic compound content of tree cores is an inexpensive,
rapid, simple approach to examining the distribution of subsurface volatile organic
compound contaminants. The method has been shown to detect several volatile
petroleum hydrocarbons and chlorinated aliphatic compounds associated with vapor
intrusion and ground-water contamination. Tree cores are obtained by using an
increment borer. The cores are placed in vials and sealed. After a period of
equilibration, the cores can be analyzed by headspace analysis gas chromatography.
Don Vroblesky of the United States Geological Survey will discuss the recently
published "User's Guide to the Collection and Analysis of Tree Cores to Assess the
Distribution of Subsurface Volatile Organic Compounds" that describes the method.
The guide helps environmental professionals unfamiliar with the tools and methods of
tree coring and contributes understanding to the relevant underlying tree physiology.
