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,

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 .  
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 or .  
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 or .  
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 .

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 .  
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).
