Upcoming Live Internet Seminars
December is a busy month at the CLU-IN Studio. We are offering
five live seminars this month. For more information on individual
seminars, see me ://clu-in.orq/studio . They include:
Handbook of Groundwater Protection and Cleanup Policies for
RCRA Corrective Action - December 5 - SOLD OUT
Remediation System Evaluation and Optimization of Pump and
Treat Projects - December 10. The objective of this presentation is
to enhance current understanding of the Remediation System
Evaluation (RSE) process and optimization tools available to site
managers of pump and treat systems. RSEs aim to improve the
efficiency of operation and maximize the remedy's effectiveness by
identifying ways to reduce O&M costs, shorten closure time, verify
clear goals and exit strategy, and assure equipment is adequately
maintained. Pump and treat systems have been operating for two
decades and this experience has led to large gains in knowledge
and understanding.
ITRC In Situ Chemical Oxidation - December 11. The purpose of
this training is to familiarize participants with the recently released
ITRC In Situ Chemical Oxidation Technical and Regulatory Guidance
document. It provides technical and regulatory information to help
you understand, evaluate and make informed decisions on ISCO
proposals. Included is a description of the various chemical oxidants,
regulatory considerations, stakeholder concerns, case studies, and
technical references.
Geophysical Characterization Techniques and Data Uses -
December 12. Learn to identify and understand factors to be

considered in scoping, executing, or reviewing projects that involve
geophysical instruments and techniques. The two hour seminar
starts with the basic science behind geophysical technologies and
how they fit into smarter approaches to cleaning up hazardous waste
sites. The seminar then walks you through the use several of
technologies such as resistivity profiling and ground penetrating
radar. Throughout the seminar, instructors describe how the use of
systematic planning, dynamic work plans, and field technologies
(a.k.a. the Triad) is applied to site cleanups guided by geophysical
tools.
ITRC Advanced Techniques on Installation of Iron Based
Permeable Reactive Barriers and Non-Iron Based Barrier
Treatment Material - December 13. This is the second training on
Permeable Reactive Barrier Walls from the ITRC. It responds to
student requests to provide additional detail and describe
advancements in the science and engineering to design, install,
maintain and monitor reactive barrier systems. This curriculum will
train students using case studies to describe long-term performance
of iron-based systems and design them according to the
heterogeneities of the subsurface.
Documents and Web Resources
Development of Recommendations and Methods to Support
Assessment of Soil Venting Performance and Closure (EPA
600-R-01-070). This report was produced by the U.S. EPA Office of
Research and Development. The overall purpose of the report is to
improve the "state of the art" and "state of the science" of soil venting
application. Results of field-based research and comprehensive and
detailed literature reviews on gas flow and vapor transport are
provided to form the basis and defense of recommendations to
improve site characterization, design, and monitoring practices in
support of venting application (September 2001, 435 pages). View or
download at http://www.epa.aov/ada/pubs/reports.html . For hard copies, contact Kay
Cooper at (580) 436-8651 or fax (580) 436-8503.
Summary of Workshop on Biodegradation of MTBE (EPA
626-R-01-001A). A workshop on biodegradation of methyl tert-butyl
ether (MTBE)-contaminated soils and groundwater was held in
Cincinnati, OH, on February 1-3, 2000, and was sponsored by the
U.S. Environmental Protection Agency's (EPA) National Risk
Management Research Laboratory (NRMRL) and the American
Petroleum Institute (API). Researchers in academia, industry, and
government agencies were invited to attend and present current
research. The goals of the workshop were: to gain an understanding
of the types of MTBE research that various organizations are

conducting and of the conclusions that this research is generating; to
identify the remaining research needs on MTBE biodegradability;
and to understand what research is being planned for the future and
to identify potential opportunities for collaboration. This report
summarizes the workshop (February 2001, 45 pages). View or

Ground Water Currents newsletter - current issue (EPA
542-N01-007). This quarterly newsletter, published by the U.S. EPA
Technology Innovation Office, provides descriptions and
performance data for developments in innovative ground water
treatment. This issue highlights innovative technologies for
remediating ground water at military sites contaminated with
ordnance, MTBE, and chlorinated solvents. Currently, more than
21,000 potentially contaminated sites exist on defense-related
facilities across the country. These facilities offer unique
opportunities for collaborative efforts on technology innovation
involving the U.S. EPA, other Federal departments and agencies,
and the private sector. It is estimated that cleanup of these sites will
cost about $30 billion. View or download at http://clu-in.org/techpubs.htm . For
hard copies, contact (800) 490-9198 or (513) 489-8190 or fax to
(513) 489-8695.
Two New Citizen Guides to Innovative Technologies. The
Citizen's Guide Series are 2-page fact sheets that provide a general
description on approaches to clean up contaminated was sites. The
fact sheets cover five questions about each clean up approach:
What is it?, How does it work?, Is it safe?, How long will it take?, and
Why use it?. View or download both Citizen Guides at
http://clu-in.org/techpubs.htm . The two new Guides are:
A Citizen's Guide to Solvent Extraction (EPA 542-F-01-009), and A
Citizen's Guide to Chemical Dehalogenation (EPA 542-F-01-010).
The CLU-IN Technology Focus Area. If you need information on a
specific technology there is an improved tool on CLU-IN to shorten
your research time. Through the Technology Focus section, CLU-IN
provides a compilation of the most relevant information resources on
14 remediation technologies. These resources are presented under
5 categories for each technology such as Technology Description,
Applications, Engineering/ Regulatory Guidance, Training and
References, with a summary and direct link to each resource. For
more information, see http://clu-in .oro/techfocus/ . The technologies featured in
the Tech Focus Area include:

State Drycleaner Remediation Web Page. The State Coalition for
the Remediation of Drycleaners is made up of states with formal
drycleaner remediation programs. SCRD is now loading on the
website, case studies on the characterization and remediation of
contaminated soils and ground water drycleaning facilities. The case
studies include information on subsurface conditions,
characterization technologies, remediation efforts and results, and
lessons learned. There are over 20,000 drycleaner facilities in the
country that may need remediation and the Coalition hope that the
experiences and lessons learned from the early efforts may facilitate
more efficient future efforts. There are currently over 20 case studies
available for viewing with plans to add 20 to 30 sites in the next few
months. For more information, see http://www.drvcleancoalition.org .
Initiatives to Develop Web Sites Including Information about
Brownfields Properties (EPA 542-R-01-017). This
document/website was created to assist in planning, designing, and
operating web sites that include information about individual
brownfields properties. The report will help parties that are designing
or managing Brownfields property-listing sites. It includes suggested
minimum data requirements, functionality, reporting capabilities. The
"Initiatives" web site is based on a study conducted by the U. S. EPA
in 2000 which included input from states and national redevelopment
organizations. See http://clu-in.ora/techpubs.htm . For hard copies, contact (800)

universities. This report summarizes the experimental procedures
and initial conditions at 11 trial locations that will be monitored for
three growing seasons. A primary purpose of the RTDF trials is to
