Special Announcements

Webcast: 25 Years of Contaminated Land Management -
Achievements and Work Still to Be Done. Live from ConSoil in
Bordeaux, France, October 4, 2005. The webcast is sponsored by
the European Soil and Groundwater Remediation Information
System (EUGRIS), U.S. Environmental Protection Agency, the
Network for Industrially Contaminated Land in Europe (NICOLE),
and ConSoil 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. Panelist will
discuss technical advances and policy shifts that allowed them in the
field of contaminated site management go hand in hand and feed off
each other. Presentations in this panel review major breakthroughs
and their value going forward. Registration is required for each panel

Upcoming Internet Seminars

ITRC Site Investigation and Remediation for Munitions
Response Projects - August 2. The Department of Defense (DOD)

is currently working on an inventory of former ranges with potential
for munitions contamination. There are an estimated 2,000
munitions-contaminated sites located in all 50 states and territories
that may affect more than 10 million acres. State and tribal regulatory
officials and community stakeholders are routinely required to
evaluate DOD cleanup strategies with little, if any, environmentally
oriented munitions response experience or guidance. State
regulators are increasingly being charged with oversight
responsibility for munitions response cleanup projects on other than
operational ranges, such as formerly used defense sites (FUDS) and
base realignment and closure (BRAC) sites. In addition, DOD project
managers and industry will benefit from a greater understanding of
state regulator expectations. For more information and to register,

ITRC Geophysical Prove-Outs for Munitions Response Projects
- August 4. Geophysical systems are used to detect surface and
subsurface anomalies, (i.e. unexploded ordnance (UXO) and/or
discarded military munitions) during geophysical surveys of
munitions response sites. These systems are tested, evaluated and
demonstrated by a site-specific geophysical prove-out (GPO).
Information collected during the implementation of the prove-out is
analyzed and used to select or confirm the selection of a geophysical
system that can meet the performance requirements established for
the geophysical survey. http ://www.itrcweb.org Of htt^^/clu^iiL^^^tu^o .

NIEHS DNAPLs - Source Zone Behavior and Mass Flux
Measurement - August 10. This seminar is the first in a series
sponsored by the National Institue for Environmental Health Studies
(NIEHS) Superfund Basic Research Program. The presence of
source zones containing dense non-aqueous phase liquid (DNAPL)
is usually the single most important factor limiting the
characterization and cleanup of organic-contaminated sites. To
address the source-reduction issue and mass flux measurements, as
well as to accurately assess the human-health risks associated with
chlorinated solvents and other DNAPLs in the subsurface, it is
essential to gain a better understanding of the distribution and
mass-transfer behavior of DNAPLs in subsurface systems. To
reserve a spot on the seminar, register at	Additional

SBRP seminars in September and October will address DNAPLs
monitoring, biological remediation, and chemical/physical
remediation methods.

ITRC Radiation Risk Assessment: Updates and Tools - August

11. The Radionuclides Team of ITRC has developed a document,
Determining Cleanup Goals at Radioactively Contaminated Sites:

TechDirect: August 1, 2005

-------
Case Studies (RAD-2, 2002), that examines the factors influencing

the variations in cleanup level development at various radioactively

contaminated sites. This document underscores the need for

radiation risk assessment training to enhance consistency in risk

assessment application. The document also acknowledges the

differences between the 'dose approach' used at some sites and

EPA's 'risk-based approach'. Since most radioactively contaminated

DOE and DOD sites are developing cleanup goals under CERCLA

authority, there is a need for a training course that clarifies the

variations between these approaches and elaborates on the

methodology used to develop risk-based remediation goals. To meet

this need, this training course has been collaboratively developed by

the ITRC Radionuclides Team and EPA's Superfund Office. The

focus of this training is EPA's new radiation risk assessment tools,

which can facilitate better decision making for accelerated cleanups.httP://™.^web.™

audio-visual files. It includes existing publically-available software,
published guidance, journal articles; reports, internet web sites, video clips,
and other information relating to site characterization; obtaining
representative samples from heterogeneous media; developing conceptual
site models; managing uncertainty in environmental decision making;
illustrating sampling, analytical, data management, and data presentation
methodologies; and illustrating innovative site characterization technologies
(June 2005). Copies can be ordered from NSCEP at (800) 490-9198 or
(513) 489-8190 or fax to (513) 489-8695. Please note that it is available in
TWO (2) different formats. Please specify either the DVD or the CD format.

Proceedings for the 2005 International Phytotechnologies Conference
are now available! This conference was organized by the Environmental
Protection Agency and answered the persistent questions of what
contaminants can plants clean, how long will it take, and how much money
can be saved over conventional technologies. Fourteen different sessions
were held, with representation from 24 different countries. To view the
proceedings, see http ://clu-in. org/phvtoconf/agenda.cfm . Also on this website are the
proceedings from the 2000 and 2003 Phytoremediation Conferences along

(GAO-05-666). This report was published by the General Accounting
Office. It reviews DOD's current use of groundwater remediation
technologies and the extent to which the department is researching
and developing new approaches. The Department of Defense has
used, or at least tested, all of the generally accepted technologies
currently available to remediate contaminated groundwater, including
several alternatives to pump-and-treat (June 2005, 46 pages). View

or download at http://clu-in.org/techpubs.htm .

A Guide to the Proper Selection and Use of Federally Approved
Sediment and Water-Quality Samplers (USGS 2005-1087). This
report was published by the U.S. Geological Survey. As interest in
the health of rivers and streams increases, and new water-quality
regulations are promulgated, interest in sediment and water-quality
sampling equipment and technologies has increased. While much
information on the subject exists, a comprehensive summary
document of sediment sampling equipment and technology is
lacking. This report seeks to provide such a summary. The purpose
of this report is to provide (1) a general understanding of sediment
sampling equipment and technology, (2) guidance for the selection
of the appropriate equipment, and (3) an introduction to new Federal
Interagency Sedimentation Project (FISP) approved sampling
equipment (2005, 26 pages). View or download at

Technology News and Trends-current issue (EPA 542-N-05-004).
Technology News and Trends is published by the EPA Office of
Superfund Remediation and Technology Innovation. This issue
covers several innovative projects including: (1) enhanced
bioremediation of groundwater; (2) continued progress applying the
Triad approach for NAPL; and (3) Supermulch amendment for
revegetation at a mining site. View or download at, http://clu-in.org/techpubs.htm .
