Open Solicitations
NIEHS. The National Institute of Environmental Health Sciences
(NIEHS) is announcing a new funding opportunity as part of the
Superfund Basic Research and Training Program (SBRP). The
title is 'Innovative Approaches to Remediation of Recalcitrant
Hazardous Substances in Sediments' and will be awarded under
the Individual Research Project Program (R01) mechanism of the
SBRP. The objective is to encourage research to develop
innovative approaches to address the remediation of contaminated
sediments, with particular emphasis on in situ remedies. All
accredited domestic institutions of higher education are eligible to
apply. The application receipt date is January 11th, 2007 - letters
of intent are requested by December 11, 2006. If interested in
applying, contact Heather Henry (919) 541-5330. For more information,
see http://www-apps.niehs.nih.gov/sbrp/fundi ...
SERDP. The DoD Strategic Environmental Research and
Development Program (SERDP), released its annual Core and
SERDP Exploratory Development (SEED) solicitations for FY
2008 on November 9, 2006. The Core solicitation requests
proposals in response to Statements of Need (SON) related to the
SERDP focus areas of Environmental Restoration, Munitions
Management, Sustainable Infrastructure, and Weapons Systems
and Platforms. For the SERDP Core solicitation, pre-proposals
from the non-federal sector are due January 4, 2007, and federal
proposals are due March 8, 2007. In addition, two SEED SONs
were released within the Munitions Management and Sustainable
Infrastructure thrust areas. All SERDP SEED proposals are due
March 8, 2007. For more information, see http://www.serdp.org/ .
Upcoming Live Internet Seminars
ITRC Planning and Promoting of Ecological Reuse of
Remediated Sites - December 5. This training is based on the
ITRC Technical and Regulatory Guideline: Planning and
Promoting Ecological Land Reuse of Remediated Sites (ECO-2,
2006). The document presents a process to promote ecological land
reuse activities considering natural or green technologies instead of
more traditional remedies. The guidance demonstrates that natural
or ecological end-uses are valuable alternatives to conventional
property development or redevelopment. Ecological benefits and a
process for calculating their value are included in the guidance and
reviewed in this training. For more information and to register, see
http://www.itrcweb.org or http://clu-in.org/studio .
ITRC Overview of Direct-push Well Technology for Long-
term Groundwater Monitoring - December 7. Direct-push
wells have been used for temporary groundwater monitoring
purposes for many years but are generally prohibited for use as
long-term groundwater monitoring wells. Recent research indicates
that direct-push wells are as well suited for long-term
environmental groundwater monitoring purposes as conventionally
constructed wells. This training introduces ITRC's The Use of
Direct-push Well Technology for Long-term Environmental
Monitoring in Groundwater Investigations (SCM-2, 2006),
provides a background in the principles of direct-push wells, and
presents the state of the art regarding recent research. For more
information and to register, see http://www.itrcweb.org or
http://clu-in.org/studio .
ITRC Risk Assessment and Risk Management: Determination
and Application of Risk-Based Values - December 12. This
training course describes the development and application of risk-
based screening values. The first module provides a review of key
risk assessment concepts related to risk management. The second
module focuses on the process by which risk-based levels are
derived in different states. The third module examines the
application of risk assessment to remediation operations in two
case studies providing examples of how risk assessment has
actually been implemented, based upon research and case studies
conducted by the ITRC Risk Assessment Resources team. This
training course describes a number of the reasons behind variations
in risk-based screening values and their use in risk management.

Revegetation and Restoration of an Oil Contaminated Wetland
in Northern New Jersey - December 14. This presentation will
attempt to show that a carefully supervised cleanup followed by a
scientifically driven monitoring program can be effective in
removing oil from a sensitive wetland habitat using the Green
Pond Oil Spill Removal project as the prime example. A
monitoring program for determining the success of the
revegetation/restoration effort was conducted. Species composition
and productivity measurements were an integral part of the
parameters to measure the progress of the effort to determine
comparability between the remediated site and undisturbed
wetlands. The presentation will incorporate all that has been
learned from the removal activity in terms of How Clean is Clean
as applied to an oil contaminated fresh water wetland. This
information should be useful for decision makers, responders, and
consultants alike when faced with remediating disturbed or
contaminated habitats. For more information and to register, see
http://clu-in.org/studio .
Documents and Web Resources
Treatment Technologies for 1,4-Dioxane: Fundamentals and
Field Applications (EPA 542-R-06-009). 1,4-Dioxane is a
solvent stabilizer frequently found at contaminated sites where
methyl chloroform (1,1,1-trichloroethane) was used for degreasing.
This report profiles the occurrence and properties of 1,4-dioxane
and provides a summary of the available remedial technologies.
The information presented should prove useful to project managers
and other regulatory officials who oversee cleanup of contaminated
groundwater, particularly where chlorinated solvents are the
principal contaminant. Consultants, including hydrogeologists,
remediation engineers, and modelers, should also find this report
useful, as should water utility operators and regulators (November
2006, 30 pages). View or download at http://clu-in.org/techpubs.htm .
In Situ Treatment Technologies for Contaminated Soil (EPA
542-F-06-013). This issue paper provides summary information
on a wide variety of in situ technologies for the treatment of
contaminated soil in both the vadose zone and saturated and
unsaturated zones. The document presents information on
common practices such as soil vapor extraction and bioventing,
and less frequently used technologies such as in situ thermal
treatment. This information is intended to give project managers a
basic understanding that will allow for further consideration of the
technology's applicability at a site (November 2006, 35 pages).
