Open Solicitation  
  
ESTCP FY 2009 SEED Solicitation. The Department of Defense   
(DoD), through the Environmental Security Technology   
Certification Program (ESTCP), is seeking innovative   
environmental technology demonstrations as candidates for   
funding beginning in Fiscal Year (FY) 2009. This solicitation   
requests pre-proposals via Calls for Proposals to DoD   
organizations and Federal (Non-DoD) organizations, and via a   
Broad Agency Announcement (BAA) for Private Sector   
organizations. ESTCP is seeking proposals from Non-DoD Federal   
organizations for environmental technologies in the following   
topics only: 1) Remediation of Contaminated Groundwater; 2) In   
Situ Remediation of Contaminated Sediments; 3) Characterization,   
Control, and Treatment of Range Contamination; 4) Military   
Munitions Detection, Discrimination, and Remediation; 5) Control   
of Non-Native Invasive Species on Department of Defense Lands   
and Waters; and 6) Energy Efficiency and Renewable Energy for   
DoD Installations. Pre-proposals are due by Thursday, March 13,   
2008. Information about the solicitation and instructions for   
submitting proposals are available at

Characterizing Mass Transfer and Mass Flux for DNAPL Source   
Zones - February 5. To accurately assess the human health risks   
associated with DNAPLs in the subsurface, and to design   
effective remediation systems for such contamination, it is   
essential to understand contaminant mass-transfer and mass flux   
behavior associated with DNAPL source zones. The contaminant   
mass flux or mass discharge emanating from a source zone, also   
referred to as the source strength or source function, is a   
primary determinant of the risk associated with a contaminated   
site. Concomitantly, the reduction in mass flux achieved with a   
specific level of source-zone mass removal (or mass depletion)   
is a key metric for evaluating the effectiveness of a   
source-zone remediation effort. Thus, there is great interest in   
characterizing, estimating, and predicting relationships between   
mass flux reduction and mass removal. The nature of the   
relationship between mass flux reduction and mass removal will   
be mediated by the properties and distribution of the porous   
medium and of the DNAPL (source-zone architecture), and their   
resultant impacts on the pore-water velocity field and   
mass-transfer dynamics. In addition, the relationship between   
mass flux reduction and mass removal may change with time due to   
temporal changes in source-zone architecture and mass-transfer   
dynamics (i.e., source-zone aging). Furthermore, the   
mass-flux-reduction/mass removal relationship may be affected by   
source-zone remediation efforts. These issues will be   
illustrated using the results of studies spanning a range of   
spatial and temporal scales. For more information and to

Community Action for a Renewed Environment (CARE) National   
Webcast for the 2008 Request for Proposal - February 11 and 27.   
This webcast is an opportunity for potential applicants to the   
CARE cooperative agreement program to learn more about and ask   
questions about the Request for Initial Proposals that was   
issued in December 2007. Visit www.epa.gov/CARE for more   
information on the CARE program. To register, see

ITRC Protocol for Use of Five Passive Samplers - February 21.   
This training supports the understanding and use of the ITRC   
Protocol for Use of Five Passive Samplers to Sample for a   
Variety of Contaminants in Groundwater (DSP-5, 2007). The five   
technologies included in this document include diffusion   
samplers, equilibrated grab samplers; and an accumulation   
sampler. The training starts with information common to all five   
samples then focuses on each sampler as instructors describe the   
sampler and explain how it works; discuss deployment and   
retrieval of the sampler; highlight advantages and limitations;   
and present results of data comparison studies. For more

ITRC Performance-based Environmental Management - February 26.   
Performance-based environmental management (PBEM) is a   
strategic, goal-oriented methodology that is implemented through   
effective planning and decision logic to reach a desired end   
state of site cleanup. The goal of PBEM is to be protective of   
human health and the environment while efficiently implementing   
appropriate streamlined cleanup processes. This ITRC training   
presents an overview of what PBEM is, explains how and when to   
implement it, and describes the issues that regulators are   
concerned about throughout PBEM's implementation. Case studies   
will be presented to illustrate successful PBEM projects. The   
course is valuable not only because PBEM is being proposed and   
implemented at many federal and private sites throughout the   
country, but also because PBEM provides an opportunity to   
enhance all site remediation. For more information and to

A Systematic Approach for Evaluation of Capture Zones at Pump   
and Treat Systems (EPA 600-R-08-003). This document was   
published by the U.S. EPA Office of Research and Development.   
It describes a systematic approach for performing capture zone   
analysis associated with ground-water pump and treat (P&T)   
systems. This analysis is meant to determine the zone of   
hydraulic control of a P&T system. The intended audience for   
this document is technical professionals that actually perform   
capture zone analyses (i.e., hydrogeologists, engineers) as well   
as project managers who review those analyses and/or make   
decisions based on those analyses (January 2008, 166 pages).

Groundwater Monitoring Network Optimization, Frontier Hard   
Chrome Superfund Site, Vancouver, Washington (EPA 542-R-07-021).   
This report reviews and provides recommendations for instituting   
a long-term groundwater monitoring network for Frontier Hard   
Chrome (FHC) Superfund Site in Vancouver, Washington. The FHC   
Site is a former chrome plating facility in the floodplain of   
the Colombia River. The current FHC groundwater monitoring   
network has been evaluated using a formal qualitative approach   
as well as statistical tools found in the Monitoring and   
Remediation Optimization System software (MAROS).   
Recommendations are made for groundwater sampling frequency and   
location based on current hydrogeologic conditions and long-term   
monitoring goals for the system. The primary goal of developing   
an optimized groundwater monitoring strategy at the FHC Site is   
to create a dataset that fully supports site management   
decisions while minimizing time a
