> 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

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.

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 information and to register, see http://ciu-in.ora/studio .

Proven Technologies and Remedies Guidance - Remediation of Metals in Soil.

The California Department of Toxic Substances Control (DTSC) has released a new
guidance document that presents an option for expediting and encouraging cleanup of
sites with elevated concentrations of metals in soil. The guidance is applicable on a
case-by-case basis to operating and closing hazardous waste facilities and Brownfields
sites. The approach streamlines the cleanup process by (1) limiting the number of
evaluated technologies to two cleanup alternatives: excavation/disposal and
containment/capping; (2) providing guidance for establishing background
concentrations, screening levels, and cleanup goals; and (3) providing resources that
facilitate remedy implementation, documentation, and administrative processes. View

CLEA UK, the previous version of the software. You can use the CLEA software to
derive generic soil assessment criteria using generic assumptions about the
characteristics of contaminants and people likely to be present on site; derive
site-specific soil assessment criteria by entering your own data on the characteristics of
contaminants and people likely to be present on site and/or using a non-generic
approach; and assess whether a measured concentration in soil (and where available,
measured site concentrations for contaminants within soil air, ambient and indoor air,
and fruits and vegetables) would present a potential risk to human health for a particular
set of circumstances. View or download at
