The purpose of TechDirect is to identify new technical, policy and
guidance resources related to the assessment and remediation of
contaminated soil and ground water.
Mention of non-EPA documents or presentations does not constitute
a U.S. EPA endorsement of their contents, only an acknowledgment
that they exist and may be relevant to the TechDirect audience.
Internet Seminars
This summer we made a series of equipment improvements to the
CLU-IN system that hosts the internet seminars and supplies the
audio streaming. The consistency and quality of the audio stream are
much better than with the old equipment. Transition between slides
is now much faster. If you have not tried the audio streaming option
in a while or were put off by a previous bad experience, we suggest
trying it now. October is another busy month for live seminars.
RCRA Sites and EPA Brownfield Grants - October 7. This
session hosted by the U.S. EPA, will cover the FY04 U.S. EPA
Brownfield Grants application process (deadlines and logistics), the
types of RCRA site projects that were included in last year's
Brownfield Grant applications, and the types of RCRA site projects
might be appropriate for a future application. For more information
and to register, see http://clu-in.org/studio .

NIEHS/EPA PCBs - Monitoring and Detection - October 15. This
seminar will discuss the limitations of Aroclor (commercial PCB
mixture) analysis and why congener analysis provides for better
decision-making with regards to human health and ecological risks of
exposure to polychlorinated biphenyls (PCBs). Register to participate
at http://clu-in.ora/studio .
ITRC Systematic Approach to In Situ Bioremediation in
Groundwater: Nitrates, Carbon Tetrachloride & Perchlorate
October 21. This course presents a decision tree for reviewing,
planning, evaluating, and approving in situ bioremediation (ISB)
systems in the saturated subsurface. It defines site parameters and
appropriate ranges of criteria necessary for characterization, testing,
design and monitoring of ISB technologies. Register to participate at

ITRC Surfactant/Cosolvent Flushing of DNAPL Source Zones -
October 23. The purpose of this training is to familiarize you with the
ITRC Technical and Regulatory Guidance for Surfactant/Cosolvent
Flushing of DNAPL Source Zones (DNAPL-3). This document
provides technical and regulatory information to help you
understand, evaluate and make informed decisions regarding
potential surfactant/cosolvent flushing projects. Register to
participate at http://www.itrcweb.org Of http://clu-in.org/studio .
NIEHS/EPA PCB Remediation, October 28. This seminar will
present the latest advances in PCB bioremediation research. This
involves genome sequencing and other genomic tools to evaluate
the consequences of pollutant exposure on the overall bacterial
community genome. The health of this genome is critical for effective
bioremediation of PCBs to a biologically acceptable endpoint. In
addition, presenters will examine the lessons learned from the PCBs
found in dated sediment cores taken from the Hudson River in New
York and New Jersey. Cores from depositional areas have been
used to determine the history of PCB contamination, the progress of
in situ dechlorination of PCBs, and the extent of influence of PCB
inputs to the upper Hudson. Register to participate at http://clu-in.org/studio .

Environmental Technology Verification Report Ground Water
Sampling Technologies Geoprobe Inc. Pneumatic Bladder
Pump, GW1400 Series (EPA 600-R-03-085). This report was
prepared by the EPA ETV program. The performance of
ground-water sampling technologies was evaluated at the US
Geological Survey Hydrological Instrumentation Facility at the NASA
Stennis Space Center in southwestern Mississippi and at Tyndall Air
Force Base near Panama City, Florida. Each technology was
independently evaluated to assess its performance in the collection
inorganic cations, commonly encountered in ground-water, as well
as volatile organic compound- (VOC) contaminated ground-water
(August 2003, 54 pages). Details of the test results are provided in
