Mining Site Metals: Exposure Pathways and Bio-Assays - September 3, 2013,
1:00PM-3:00PM EDT (17:00-19:00 GMT). This two-part seminar will feature Dr.
Miranda Loh and Dr. Robert Root from the University of Arizona Superfund Research
Program and will focus on characterizing arsenic exposure at a former mine and
smelter site in Arizona. At the Iron King Mine and Humboldt Smelter Superfund Site in
Dewey-Humboldt, AZ, issues of concern include: metal contamination from mine
tailings; high levels of naturally-occurring arsenic in soil and groundwater; and
residents' exposure to these contaminants. Dr. Miranda Loh will describe her work
characterizing exposure pathways in the Metals Exposure Study in Homes. This study
investigates whether there is a relationship between living near a former mine and
smelter site and children's exposure to metals, particularly arsenic and lead, via soil,
dust, and water. Metals were measured in residential soil, dust, water, urine, blood, and
toenail samples from multiple children in 34 households up to 5 miles from the site, and
compared to national studies. To further understand potential exposures, Dr. Robert
Root will describe his work combining in vitro bio-assays with molecular-scale
speciation to interrogate the bioaccessibility of arsenic in mine tailings.Collected surface
particles, tailings, and efflorescent salts were reacted with synthetic lung and gastric
fluids and analyzed by synchrotron x-ray spectroscopy for arsenic speciation. Results
show that the fraction of metals released varies by particulate type as well as by
bio-fluid type, which may have implications for exposure risk. For more information and

water. LNAPLs are important because they are present in the subsurface at thousands
of remediation sites across the country, and are frequently the focus of assessment and
remediation efforts. Part 1 of this training course explains how LNAPLs behave in the
subsurface and examines what controls their behavior. Part 1 also explains what
LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical
examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization
and site conceptual model development as well as LNAPL recovery evaluation and
remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when
and why those data may be important, and how to get those data. Part 2 also
discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual
site model (LCSM) approach to identify the LNAPL concerns or risks and set proper
LNAPL remedial objectives and technology-specific remediation goals and performance
metrics. Part 3 also provides an overview of the LNAPL remedial technology selection
framework. For more information and to register, see http://www.itrcweb.ora or http://ciu-in.ora/iive .

Reuse Planning at Superfund Sites: A Little Planning Can Go a Long Way -
September 16, 2013, 3:30PM-5:30PM EDT (19:30-21:30 GMT). Stakeholder and
community involvement are integral parts of EPA's mission and necessary components
of successful site reuse. Superfund site reuse planning provides a unique opportunity
for stakeholders and EPA to collaborate on the redevelopment and reuse of Superfund
sites at appropriate times before, during, and after site cleanup has been completed. It
is never too late or too early to think about reuse at a site. EPA's Superfund
Redevelopment Initiative (SRI) supports communities nationwide interested in
reintegrating Superfund sites into the fabric of their neighborhoods and towns through
beneficial reuse. This webinar will introduce reuse planning, discuss how value is
added at various levels of reuse planning engagement, and review tangible and
intangible benefits of reuse planning for EPA, the community and the site. Using case
studies from across the nation, this webinar will share how effective reuse plans and
support from EPA programs such as SRI can bring communities together, build
goodwill for EPA and determine the most appropriate reuse options for Superfund sites.

Groundwater High-Resolution Site Characterization (HRSC), Chicago, IL,
September 24-25, San Francisco, CA, December 12-13. This is a two-day training
course that focuses on groundwater characterization and discusses (1) the impacts of
subsurface heterogeneity on the investigation and cleanup of groundwater and related
media, (2) the need for scale-appropriate measurements and adequate data density,
and (3) the tools and strategies that are available to overcome the impacts of
subsurface heterogeneity. After taking this course, participants will be armed with
information that will allow them to improve their subsurface investigation approaches
and develop more realistic and comprehensive conceptual site models (CSM). CSMs
developed based on HRSC strategies and tools will decrease site uncertainty, improve
the remedy selection process for groundwater remedies, and better enable the
evaluation, design, and implementation of targeted in situ and ex situ groundwater
remedies. The recommended audience for this course includes EPA, federal, state,
tribal, and private industry technical project managers, practitioners and other
stakeholders involved in groundwater investigation and remediation. For more

U.S. EPA's Region 9 State-of-the-Science Workshop on Mercury Remediation in
Aquatic Environments, San Francisco, CA, September 26, 2013. As part of
implementing EPA Region 9's strategic plan, ORD and the Region are planning a state
of the science workshop to investigate the latest in remediation techniques for mercury
contaminated sites in aquatic environments. The workshop will be held on Thursday,
September 26th at the EPA office in San Francisco. Participation is also possible via
webinar. The objective is to understand the key mechanisms linking source loads,
methylation, and bioaccumulation of mercury to guide future remediation decisions.
The workshop will examine the effect of current remediation practices, such as
removing/capping lake sediments, isolating retort or tailings from waters, and on levels
of mercury in fish tissue. We want to know whether removing these mercury sources
have a real effect on fish tissue levels and to understand the key mechanisms that
actually cause fish tissue levels to drop. And we want to better understand what will
directly affect the methylation process at specific sites so that concrete actions can be
taken to reduce fish tissue levels. The workshop is open to anyone working on or
interested in this topic - regulators, industry, academics and consultants are all invited.
There is no cost for the workshop. There are hookup limits to the webinar option, so if
you are aware of other interested colleagues, please consider sharing a single
registration.For more information and to register, see http://www.trainex.ora/ha.
