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.

ITRC LNAPL Training Parts 1, 2, and 3  September 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.org or http://clu-in.org/live .

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.

RE-Powering Mapper. Many contaminated lands, landfills, and mine sites are particularly well-suited for renewable energy development because they are situated in close proximity to critical infrastructure such as electric transmission lines and roads, located near areas with high energy demands, and offered at lower land costs when compared to open space. The U.S. Environmental Protection Agency (EPA) RE-Powering America's Land initiative recently released an updated RE-Powering Mapper tool that provides preliminary screening results for renewable energy potential at contaminated properties tracked by EPA and partnering state agencies. Through continued collaboration with the U.S. Department of Energy's National Renewable Energy Laboratory, the tool now covers more than 66,000 sites and includes screening criteria for solar, wind, biomass, and geothermal potential at various levels of development. States with agencies that have joined this effort include California, Hawai'i, Oregon, Pennsylvania, New Jersey, New York, West Virginia, and Virginia.

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 information and to register, see http://www.trainex.org/hrsc .

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.org/hg .
