Superfund Research Program Sediment Bioavailability Assays - Kick-off Webinar
Featuring New Research Projects - May 7, 2012, 3:00PM-5:00PM EDT (19:00-21:00
GMT). This webinar will be comprised of 5 short presentations from the Superfund
Research Program Individual Research Grants (R01).The NIEHS Superfund Research
Program (SRP) released a funding opportunity announcement in 2010 titled RFA
ES-11-005 "Innovative Bioavailability Assays to Assess the Effectiveness of
Contaminated Sediment Remediation (R01)." This solicitation called for the
development of innovative assays of bioavailability that may be used to determine the
effectiveness of sediment remediation in reducing risks to humans. The ultimate goals
of this solicitation are two-fold: first, to develop and introduce new tools to assess
whether remediation efforts are protective of human health; and second, to increase
use of bioavailability in risk assessment through providing scientifically-valid, practical,
and cost-effective tools. In response to this solicitation, five three-year awards were
made in 2011. For more information and to register, see httn://ciu-in.om/iive .

ITRC LNAPL Training Parts 1, 2, and 3 - May 10,17, 24. Light non-aqueous phase
liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum
hydrocarbon products that are immiscible with water and less dense than 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 .
Understanding Arsenic: From Vasculature to Vegetables - May 16, 2012,
1:00PM-3:00PM EDT (17:00-19:00 GMT). This two-part seminar will feature Dr. Todd
Camenisch and Monica Ramirez-Andreotta from the University of Arizona Superfund
Research Program and will focus on arsenic effects on cardiovascular development
and arsenic uptake in garden vegetables. The impact of arsenic on human health has
been largely focused on cellular transformation and cancer in adults. Mechanistic
studies of arsenic on the cardiovascular system have been limited, and even less is
known about the effects of early arsenic insult (pre- or neonatal) on cardiotoxicity. Dr.
Todd Camenisch will discuss studies using a mouse model as an intact system to
reveal mechanisms of arsenic-triggered cardiovascular toxicity during development. To
our knowledge, this is the first animal study to assess cardiovascular changes in
response to chronic exposure to environmentally-relevant concentrations of arsenic.
Measures of cardiac formation and function have revealed important effects on cardiac
development in the mouse model; outcomes and significance for cardiovascular health
in chronically-exposed populations will be discussed. There is a growing need to
accurately evaluate the toxicological risks to resident food gardeners neighboring
contaminated environments. Monica D. Ramirez-Andreotta, MPA, will report on her
study Gardenroots: The Dewey-Humboldt, Arizona Garden Project, which was
designed to determine the uptake of arsenic and lead in commonly grown vegetables in
Arizona and evaluate the possible health risks to the local population. The project
comprised a greenhouse study and a citizen science program conducted with a
community neighboring a national Superfund site. A comparative analysis was

conducted between the concentrations of arsenic and lead found in the soils, irrigation
water, edible tissues of crops from the greenhouse and residential gardens. Vegetable
intake rates were calculated to determine how much could be safely consumed at these
measured concentrations. The citizen science program will be discussed in terms of
recruitment, training, informal science learning opportunities, sample collection,
communication efforts, and potential participant educational outcomes. For more

Use of Nanomaterials for Environmental Remediation of Hazardous Waste Sites:
The Role of Nanoinformatics in Support of State Agencies' Health and Safety
Oversight Actions - May 21, 2012, 2:00PM-3:30PM EDT (18:00-19:30 GMT).
Environmental remediation, based on nanomaterials, is no longer a theoretical concept
but a proven technology. More than twenty five Superfund sites across the country are
using nanomaterials for remediation, and the use of nanomaterials continues to present
tremendous promise for technological advancements in other applications as well,
including ultra filtration of waste water. Use of nanomaterials or engineered
nanoparticles (ENPs) could be more effective and cheaper than other conventional
remediation practices or technologies. Despite the many benefits presented by ENPs,
including their ability to decontaminate pollutants, many health and safety risks have
been raised. For responsible development of ENPs and to allow this technology to play
a major role in sustaining a positive, healthy environment and a vibrant economy, these
concerns have to be addressed. Understanding the risks posed by ENPs at the state
and local government levels is a challenge, particularly when information regarding their
fate and transport or toxicity, safety and environmental impacts of most ENPs used for
remediation is lacking. State government agencies and programs will likely play a
significant role in the future in supporting EPA's work of ensuring that the employment of
nanotechnology for environmental remediation and other applications does not
significantly affect the health and safety of workers or the general public. To support
this endeavor, there is a need to identify, collect and collate relevant information relating
to nanomaterials' safety, health and toxicological properties. This presentation, given
by Dr. Ephraim Massawe of Southeastern Louisiana University, will provide EPA with
detailed framework, resulting from the inputs of various focus groups of experts,
designed to understand these information and technical needs relevant for
environmental, health and safety oversight at the state and local government levels.
The framework includes seeking to understand from various experts, working with
nanomaterials in the federal government agencies (e.g. EPA and their consultants),
their opinion regarding the minimum amount and type of information and regulatory
guidance documents needed for sustainable oversight of nanomaterials at the local
level. Also, the preliminary results of a survey conducted with the state agencies and
programs across the country to assess the information and technological needs will be
highlighted. For more information and to register, see http://ciu-in.ora/iive .
Renewable Energy on Contaminated Land: Tools for Local Governments - May
22, 2012, 2:00PM-3:30PM EDT (18:00-19:30 GMT). This webinar will provide an
overview of tools available to local governments to help them get renewable energy
projects built on contaminated land in their community. Through its RE-Powering
America's Land initiative, the U.S. Environmental Protection Agency (EPA) is
encouraging renewable energy development on current and formerly contaminated
land and mining sites. EPA has identified thousands of acres of Brownfield, Superfund,
mining, and other potentially contaminated sites with potential for utility scale solar
facilities. Siting renewable energy facilities on brownfields offers significant benefits to
communities. During this session, Shea Jones with EPA's RE-Powering America's Land
Initiative will highlight some of the recent tools developed by EPA, including two
decision trees that were created to screen potentially contaminated and underutilized
sites for solar and wind potential and a draft best practice guide for siting solar on
landfills. Joshua Huneycutt with DOE's Sun Shot Initiative will discuss DOE's
compilation of best practices titled "Solar Powering Your Community: A Guide for Local

Governments." Anjali Patel with the National Association of Local Government
Environmental Professionals (NALGEP) will provide an overview of NALGEP's
"Cultivating Green Energy on Brownfields: A Nuts and Bolts Primer for Local
Governments." Finally, Stephanie Wang with the Clean Coalition will describe the
"Local CLEAN Program Guide", which helps local policymakers and advocates across
the nation design, implement and campaign for CLEAN Programs. For more information

Superfund Redevelopment Initiative Webinar Series: Aligning Remedies with
Reuse - May 23, 2012, 2:00PM-4:00PM EDT (18:00-20:00 GMT). Superfund
Redevelopment Initiative (SRI) hosts a series of quarterly webinars on redevelopment
of Superfund sites across the country.These webinars share the history of
redevelopment, discuss the different types of reuse that are possible and share how
particular Superfund sites have become reuse success stories. In addition to the
webinar sessions, SRI also highlights a new site and its redevelopment story every
other month. For more information and to register, see http://ciu-in.ora/iive .

Technology News and Trends (EPA 542-N-12-002). This issue highlights projects
involving optimization reviews undertaken by the U.S. EPA and partnering state
agencies or site owners. Each project involved an optimization review performed by an
independent organization and funded by EPA's Office of Superfund Remediation and
Technology Innovation. The highlighted projects illustrate how optimization can be
used to modify specific components of a treatment process or monitoring program in
order to improve remedy effectiveness, reduce remedy implementation costs, and
increase technical efficiencies. The highlighted projects focus on sites with operating
remedies; however, EPA is now applying optimization to all phases of remediation,
from remedial investigation to site completion (April 2012, 6 pages). View or download

AFCEE Emerging Issues Program. The AFCEE Emerging Issues (El) Program
continues to develop data-driven information to support the AF Environmental
Restoration Program's questions and needs regarding "emerging contaminants" (ECs)
at restoration sites. For environmental restoration purposes, EC's are site-specific
based on regional or state regulatory standards and/or site-specific conditions, and will
fall under one of two general classes: (1) ECs may be "emerging" because the
compounds have never been considered at environmental restoration sites, (i.e. have
never been included as a Contaminant of Potential Concern (COPC)), and have
substantial data gaps regarding extent of AF contamination, sufficient analytical
methods, and/or toxicity of the EC, (2) a contaminant may be "emerging" due to a
revision to or change in that compound's regulatory risk drivers, (i.e. regulatory
standards are changing, however the AF already has systems or strategies in place to
address the EC; e.g.TCE). Currently, the El Program is filling key data-gaps for
perfluorinated compounds (PFCs), supplying needs and objectives for AFCEE Broad
