ConSoil 2008 Special Sessions on Green Remediation (June 5) and Brownfields,
Bioenergy and Biofeedstocks (June 6).EPA is collaborating with the European
Groundwater and Contaminated Land Information Portal to bring to you live, via
Webcast, two 90-minute special sessions on sustainability and contaminated site
cleanup. These sessions are being held at the 2008 ConSoil Conference in Milan, Italy.
The sessions link two important emerging themes for contaminated land management,
both connected with improving its sustainability and reducing its cost. The first theme is
the integration of land management of large areas with re-use for non-food crops,
ecosystem recovery and revenue generation. The second theme is what is termed
"green remediation," which maximizes the net environmental benefit of contaminated
land remediation techniques. For more information and to register, see http://ciu-in.ora/studio .
ITRC Performance-based Environmental Management - June 5.
Performance-based environmental management (PBEM) is a strategic, goal-oriented
methodology that is implemented through effective planning and decision logic to reach
a desired end state of site cleanup. The goal of PBEM is to be protective of human
health and the environment while efficiently implementing appropriate streamlined
cleanup processes. This ITRC training presents an overview of what PBEM is, explains
how and when to implement it, and describes the issues that regulators are concerned
about throughout PBEM's implementation. Case studies will be presented to illustrate
successful PBEM projects. The course is valuable not only because PBEM is being
proposed and implemented at many federal and private sites throughout the country,
but also because PBEM provides an opportunity to enhance all site remediation. For

Bioavailability of Organic Compounds: Methods and Case Studies - June 11. The
Superfund Basic Research Program (SBRP), in collaboration with the Environmental
Protection Agency (EPA) Technology Innovation Program, presents "Bioavailability of
Organic Compounds: Methods and Case Studies". Dr. Edward Neuhauser, Principal
Environmental Engineer, National Grid, will present a PAH measurement method, the
Solid-Phase Microextraction (SPME) method, that actually measures the true
bioavailability of PAH's in sediments. The SPME method does not measure the total

amount of PAH's present in a sediment sample, but rather only that fraction of PAH's in
sediments that are actually present in sediment pore water and are available to benthic
organisms. Dr. Danny Reible, the Bettie Margaret Smith Chair of Environmental Health
Engineering at the University of Texas, will focus on efforts to understand and quantify
exposure and risk to contaminants in sediments, including access to those
contaminants, the extent to which accessible contaminants are bioavailable and the
extent to which contaminants accumulate in organisms of interest. For more information
and to register, see http://ciu-in.ora/studio .
ITRC Perchlorate Remediation Technologies - June 12. 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 http://www.itrcweb.ora or
http://clu-in.org/studio .
Use of Bioavailability Information at Hazardous Waste Sites - June 18. The
Superfund Basic Research Program (SBRP), in collaboration with the Environmental
Protection Agency (EPA) Technology Innovation Program, presents "Use of
Bioavailability Information at Hazardous Waste Sites". Dr. Mike Beringer, U.S. EPA
Region VII toxicologist, will summarize EPA's "Guidance for Evaluating the
Bioavailability of Metals in Soils for Use in Human Health Risk Assessment" and the
basis for the Office of Superfund Remediation and Technology Innovation's decision
regarding the two methodologies for predicting lead relative bioavailability in
"Estimation of Relative Bioavailability of Lead in Soil and Soil-like Materials Using In
Vivo and In Vitro Methods." Dr. Mark Maddaloni, U.S. EPA Region II toxicologist, will
present a case study for using bioavailability data to inform and refine site specific risk
assessments at a RCRA Corrective Action site with arsenic-contaminated soil. For
more information and to register, see http://ciu-in.ora/studio .
ITRC An Overview of Direct-push Well Technology for Long-term Groundwater
Monitoring - June 19. Direct-push wells have been used for temporary groundwater
monitoring purposes for many years but are generally prohibited for use as long-term
groundwater monitoring wells. Recent research indicates that direct-push wells are as
well suited for long-term environmental groundwater monitoring purposes as
conventionally constructed wells. This training introduces ITRC's The Use of
Direct-push Well Technology for Long-term Environmental Monitoring in Groundwater
Investigations (SCM-2, 2006), provides a background in the principles of direct-push
wells, and presents the state of the art regarding recent research. For more information
and tO register, see http://www.itrcweb.ora or http://clu-in.ora/studio .
ITRC Enhanced Attenuation of Chlorinated Solvents: A Site Management Tool -
June 26. This training on the Technical and Regulatory Guidance for Enhanced
Attenuation: Chlorinated Organics (EACO-1, 2008) describes the transition (the bridge)
between aggressive remedial actions and MNA and vice 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

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat
Systems - July 21. 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 for the course is project managers who review these 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

Detailed Hydraulic Assessment Using a High-Resolution Piezocone Coupled to
the GeoVIS. The objective of this effort was to conduct a full-scale demonstration of the
use of the high-resolution piezocone and GeoVIS to determine direction and rate of
ground water flow in three dimensions. While the GeoVIS did not provide effective
porosity values within the anticipated range, the high-resolution piezocone and resulting
models fall within the quantitative tolerances set forth in this demonstration. Therefore,
the sensor probe approach to determining hydrogeologic characteristics is deemed
appropriate for the demonstration site characteristics. When compared to conventional
approaches comprised of clustered well installations, aquifer tests, sample analyses,
and three-dimensional and cross-sectional interpolations, cost savings for flux
distribution determination using the high-resolution piezocone coupled with a
membrane interface probe system exceeds 60 percent (April 2008, 360 pages). View

Incorporating Sustainable Practices into Site Remediation (EPA 542-F-08-002).
Green Remediation is the practice of considering all environmental effects of remedy
implementation and incorporating options to maximize net environmental benefit of
cleanup actions. This introduction is the first of a series of fact sheets on the
opportunities for implementing best management practices (BMPs) of green
remediation (April 2008, 2 pages). View or download at http://ciu-in.ora/techpubs.htm .
Emerging Contaminant Fact Sheets (2008). An "emerging contaminant" is a chemical
or material that is characterized by a perceived, potential, or real threat to human health
or the environment or a lack of published health standards. A contaminant may also be
"emerging" because a new source or a new pathway to humans has been discovered
or a new detection method or treatment technology has been developed. These fact
sheets, developed by the U.S. Environmental Protection Agency (EPA) Federal
Facilities Restoration and Reuse Office (FFRRO), provides brief summaries for
emerging contaminants: 1,2,3-Trichloropropane (TCP) (EPA 542-F-07-008), 1,4
Dioxane (EPA 542-F-07-004), N-Nitrosodimethylamine (NDMA) (EPA 542-F-07-006),
Perchlorate (EPA 542-F-07-003), Polybrominated Diphenyl Ethers (PBDE) and
Polybrominated Biphenyls (PBB) (EPA 542-F-07-007), Tungsten (EPA 542-F-07-005).
