Special Announcement

In Situ Thermal Technologies Netcast. On June 7, the U.S. EPA
Technology Innovation Office will sponsor a LIVE netcast of the In
Situ Thermal Seminar being held in Boston. This conference
features eight presentations focused on different methods of
introducing heat to the subsurface for vadose and groundwater
source zone remediation. We have posted the presentations on
CLU-IN and will have a live audio feed from the conference in
Boston. The conference begins at 8:30 am Eastern Daylight Time
(12:30 GMT) and continues until 4:30 pm EDT (20:30 GMT). If you
are able to play Real Audio broadcasts, you will be able to participate
FROM ANYWHERE AROUND THE WORLD. You will be able to
listen to the presentations while viewing the presenters' slides on the
web. No registration required to participate in the netcast. For more
information and the agenda, se&tte ://clu-in.orq/thermal .

Applicability of RCRA 3020(b) to In-Situ Bioremediation
Technologies. This letter was issued by the U.S. EPA Office of
Solid Waste. It addresses the condition in section 3020(b)(2) that the
contaminated ground water be treated to substantially reduce
hazardous constituents prior to such injection. The substantial
reduction of hazardous constituents required by 3020(b) may occur
after reinjection. View or download at View or download at

Application of Field-Based Characterization Tools in the
Waterfront Voluntary Setting. This report was developed by Brian
Pietruszewski, a National Network for Environmental Management
Studies Fellow under grant to EPA. Voluntary action to redevelop

potentially contaminated property operates under vastly different
market constraints than mandated corrective action programs.
Pressures exist that impact the time scale, cost/benefit ratio,
priorities, and resources that allow the action to transpire.

Non-market pressures, usually in the form of regulation, also affect
decisions over the course of redevelopment. Together, these forces
also determine the technologies and methods used to characterize
the property, as well as the media sampled. This report will
investigate the reasons behind that and detail the current level of
field-based characterization tool application at 115 waterfront
brownfield and Voluntary Cleanup Program (VCP) sites [December
1999, 67 pages]. View or download at http://clu-in.org/techpubs.htm . FOT hard

Remedial Systems Optimization. The Federal Remediation
Technologies Roundtable (FRTR) homepage has assembled a
number of remediation system optimization information resources.
The page includes a summary of last summer's conference, several
guidance documents, ongoing research and optimization tools and
models. It is a rich resource for those interested in optimizing the
performance of remedial systems. For more information, see

Ground Water Currents (EPA 542-N-00-002). This quarterly update
provides descriptions and performance data for developments in
innovative ground water treatment. This issue highlights
multi-agency efforts to accelerate the development and
implementation of innovative DNAPL remediation technologies,
research into increasing the effectiveness of permeable reactive
barriers, and development and implementation of innovative site
characterization and remediation technologies [April 2000, 4 pages].

Natural Attenuation of Explosives in Groundwater. This cost and
performance report was published by the Department of Defense
Environmental Security Technology Certification Program (ESTCP).
It summarizes a demonstration designed to define and optimize the
data collection and processing procedures for evaluation, selection,
and implementation of MNA for explosives. The demonstration was
conducted at a former waste disposal lagoon site at the Louisiana
Army Ammunition Plant, Minden, LA. Thirty wells were monitored
quarterly over a two-year period. A cone penetrometry sampling
event was also conducted to refine the conceptualization of the site
hydrogeology and to collect aquifer material for development of

microbial biomarker techniques for tracking attenuation processes. A
conceptual model of the contaminant plume was developed and a
numerical model was used to predict future plume migration and
mass [June 1999, 37 pages]. View or download at

High Resolution Seismic Reflection to Characterize and Plan
Remediation at Hazardous Waste Sites. This cost and
performance report was published by the Department of Defense
Environmental Security Technology Certification Program (ESTCP).
This report presents cost and performance data for the
three-dimensional (3-D) seismic reflection survey technique used to
generate a high-resolution, 3-D imaging of subsurface geologic,
subsurface hydro-geologic, and subsurface dense non-aqueous
phase liquid (DNAPL) contaminant source areas at four selected
Department of Defense (DoD) sites. The objective of the project was
to verify that the 3-D seismic reflection survey is a viable technique
for rapidly and effectively performing DNAPL source delineation and
high-resolution site characterization [October 1999, 40 pages]. View
