Special Announcements
Superfund En Espanol. A mediados de septiembre, la Agencia de
Proteccion Ambiental de los Estados Unidos lanzo una nueva
pagina Web en espanol, Superfund en Espanol, que le ofrece a la
comunidad hispana una amplia variedad de informacion
relacionada al Programa de Superfund. La nueva pagina Web
describe diferentes tecnologias usadas frecuentemente en los sitios
de Superfund, tales como sistemas de bombeo y tratamiento,
extraccion de vapores del suelo, cobertura de vertederos, y otros.
La pagina contiene documentos en espanol que describen el
proceso de restauracion y los metodos de la limpieza, un glosario
bilingue de terminos comunes usados en el programa de Superfund
de la EPA, y en la pagina de Preguntas Frecuentes presenta mas de
cien preguntas y respuestas con amplia informacion relacionada a
las distintas areas del programa. Ademas contiene documentos en
espanol relacionados al programa de Relaciones y Ayuda a la
Comunidad, incluyendo el Programa de Donaciones de Asistencia
Tecnica. A traves de esta p gina Web, la EPA espera proveer a la
comunidad hispana la informacion y herramientas necesarias que
les permitiran participar significativamente en el proceso de
limpieza del programa de Superfund. Para mas informacion visite

Internet Seminars
Seminar News - Many of you know that we routinely place
seminars in the CLU-IN Studio archive after they have aired. This
provides access to the slides and the audio file for each
presentation. Some of you requested that we make these audio
files more portable. Now we have done that. For more recent
seminars, you now have the option to download them in MP3
format which will allow you to listen via portable music players.
You may also subscribe to our podcast feed, which will alert you
when new seminar archives are available. For more information,
see http://clu-in.org/live/archive.cfm .
Webcast: 25 Years of Contaminated Land Management -
Achievements and Work Still to Be Done. Live from ConSoil in
Bordeaux, France, October 4, 2005. This webcast includes two
panels with four speakers each. Panel 1 is titled Shifts in
Contaminated Site Management in the EU and US and offers
insight to changes in the US and Europe to contaminated site
management over the past 25 years, and insight into future
directions. Panel 2 is titled, From Site Screening to
Redevelopment, Progress in Every Step. Presentations in this panel
review major breakthroughs and their value going forward.
Registration is required for each panel at

ITRC Permeable Reactive Barriers: Lessons Learned and New
Directions - October 6. This training presents updated
information regarding new developments, innovative approaches,
and lessons learned in the application of PRBs to treat a variety of
groundwater contaminants. The information will be presented by
reviewing the approaches and results at several sites where PRBs
have been deployed. The training is based on the ITRC guidance
document titled Permeable Reactive Barriers: Lessons Learned /
New Directions (PRB-4, 2005). For more information and to
register, see http://www.itrcweb.org or http://clu-in.org/studio.
ITRC Guidance for Characterization, Design Construction
and Monitoring of Mitigation Wetlands - October 11. This
seminar is the second in a series of wetland trainings beginning
with the ITRC Technical and Regulatory Guidance Document for
Constructed Treatment Wetlands (December 2003, WTLND-1).
To improve the success of wetland mitigation projects, this training
presents comprehensive guidance for regulators, environmental
professionals, or owners to use to understand, characterize, design,
construct, and monitor mitigation wetlands. To register, see
http://www.itrcweb.org or http://clu-in.org/studio .
ITRC Strategies for Monitoring the Performance of DNAPL
Source Zone Remedies - October 20. This training discusses
issues surrounding the assessment of remediation performance at
DNAPL sites where the source zone is being targeted for treatment.
It is based on the ITRC document titled, Strategies for Monitoring
the Performance of DNAPL Source Zone Remedies. Specific
issues dealing with monitoring the performance of various DNAPL
source zone remediation technologies are discussed. Elements of
a robust performance monitoring program are described including
the need to establish appropriate performance goals and metrics
well in advance. To register, see http://www.itrcweb.org or
http://clu-in.org/studio .
Enhanced Remediation of DNAPL-Contaminated Subsurface
Systems - October 26. This the third in a series of events
sponsored by the NIEHS Superfund Basic Research Program on
dense nonaqueous phase liquids (DNAPLs). Dr. Casey Miller, of
the University of North Carolina-Chapel Hill, will present the work
of his research group. Remediation of subsurface systems
contaminated with DNAPLs remains as one of the most difficult
open issues facing Superfund. Dr. Miller will examine the
physicochemical reasons why this is so and summarize the
challenges facing conventional remediation approaches. He will
discuss an evolving class of remediation methods based upon the
use of dense brine solutions to control the movement of DNAPLs.
Results from one-, two-, and three-dimensional laboratory studies
in heterogeneous porous medium systems will be presented. Dr.
Miller will describe results from a three-stage remediation
approach that illustrate a high fraction of DNAPL removal from
complex, heterogeneous, three-dimensional systems. Finally, he
discuss some open issues and field-scale experimentation that are in
progress. To register, see http://clu-in.org/studio .
Documents and Web Resources
Road Map to Understanding Innovative Technology Options
for Brownfields Investigation and Cleanup, Fourth Edition
(EPA 542-B-05-001). This includes new and updated resources to
assist in identification and selection of innovative site
characterization and cleanup technologies for brownfields
redevelopment. The Road Map provides a general outline of the
steps in the investigation and cleanup of a site slated for
redevelopment and introduces brownfields stakeholders to the
range of innovative technology options and resources available to
them. The Road Map provides valuable information for a wide
range of stakeholders involved in or affected by redevelopment of
brownfields sites, whether through public projects, private
developments, or public-private partnerships. The Fourth Edition
has been expanded significantly to include new and updated
resources and supplemental information with 71 new resources and
