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 register,

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
information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/studio .
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

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). View or download at http://www.epa.aov/ada/pubs/reports/600R08003.html .

-------
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 and expense
associated with collecting and interpreting data (December 2007, 101 pages). View or
download at http://clu-in.ora/techpubs.htm .
Recommendations from the EPA Ground Water Task Force (EPA 500-R-07-001).
The Recommendations from the EPA GWTF are the result of a three-year effort that
was established under the Office of Solid Waste and Emergency Response's (OSWER)
One Cleanup Program Initiative. The goal of the GWTF was to identify, prioritize, and
make recommendations for ground water issues that will benefit multiple ground water
cleanup and protection programs. The report focuses on two topics the GWTF selected
for evaluation: cleanup goals appropriate for dense non-aqueous phase liquid source
zones; and, ground water use, value, and vulnerability as factors in setting cleanup
goals. It includes background information, options, and GWTF recommendations to
address identified issues. The cover letter of the report includes the recommendations
the EPA OSWER is currently pursuing (December 2007, 82 pages). View or download

Technology News and Trends (EPA 542-N-08-001). This issue highlights strategies
for remediating sites with inorganic contaminants and radionuclides. Enhanced
research has led to increased use of bioremediation as a viable technology for
removing or transforming inorganic contaminants. Due to the length of time needed to
address radionuclide contamination, research also focuses on the potential for
monitored natural attenuation (MNA) to complement aggressive cleanup technologies
(January 2008, 6 pages). View or download at http://ciu-in.ora/techpubs.htm .
Biosolids Recycling: Restore, Reclaim, Remediate (Video). Sewage treatment
results in wastewater being recycled to the environment, but the solids removed from
wastewater can also be processed and turned into a nutrient rich fertilizer. Today's
primary use of this fertilizer is to restore overworked agricultural soils, but research by
the USDA and the USEPA/ERT has now opened the way for use of biosolids to reclaim
lands destroyed by mining. View or download video at http://www.ciu-in.ora/studio/biosoiids.cfm .

valuation approaches by explicitly considering the environment as a whole bringing
together land, water, air, soil and biodiversity and recognizing that their linkages provide
a wide variety of services and benefits that are not specific to any one part. The
approach stresses that changing any one part of our environment can have
consequences, both positive and negative, and often unintended for the ecosystem as a
whole (December 2007, 68 pages). View or download at

> Conferences and Symposia
EPA Workshop for Federal USTs, Seattle, WA, February 12-13. The U.S.
Environmental Protection Agency is hosting a free, day and a half workshop for the
federal facility community. The Energy Policy Act of 2005 included substantial revisions
to the Underground Storage Tank (UST) requirements found in Subtitle I of RCRA.
One of the major changes to the UST program resulting from the Energy Policy Act
involved periodic regulatory inspections, which are now to be conducted on a three year
cycle. Recent inspections of federal facilities by EPA have found compliance problems
not only with USTs, but also with above ground storage tanks (ASTs). Therefore,
EPA's Federal Facilities Program is hosting this workshop as a refresher on federal
tank requirements. For more information and to register, see http://www.fedcenter.aov/trainina/ust/.
