ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions - August 8, 2013, 11:00AM-1:15PM EDT (15:00-17:15 GMT). Environmental molecular diagnostics (EMDs) are a group of advanced and emerging analytical techniques used to analyze biological and chemical characteristics of environmental samples. Although EMDs have been used over the past 25 years in various scientific fields, particularly medical research and diagnostic fields, their application to environmental remediation management is relatively new and rapidly developing. The ITRC Environmental Molecular Diagnostics Fact Sheets (EMD-1, 2011), ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013) and this companion Internet-based training will foster the appropriate uses of EMDs and help regulators, consultants, site owners, and other stakeholders to better understand a site and to make decisions based on the results of EMD analyses. At the conclusion of the training, learners will be able to determine when and how to use the ITRC Environmental Molecular Diagnostics Technical and Regulatory Guidance (EMD-2, 2013); define when EMDs can cost-effectively augment traditional remediation data sets; and describe the utility of various types of EMDs during remediation activities.

Estimating Environmental Footprints Using SEFA (Spreadsheets for Environmental Footprint Analysis) - August 22, 2013, 2:00PM-4:00PM EDT (18:00-20:00 GMT). The process of cleaning up a hazardous waste site uses energy, water and other natural or materials resources and consequently creates an environmental footprint of its own. In 2012, the EPA released the "Methodology for Understanding and Reducing a Project's Environmental Footprint" which presents green remediation metrics associated with contaminated site cleanup and a process to quantify those metrics in order to achieve a greener cleanup. In conjunction with the Methodology, the EPA developed a set of analytical workbooks known as "SEFA" (Spreadsheets for Environmental Footprint Analysis), which can be used to quantify the environmental footprint of a site cleanup. This 2-hour internet seminar will provide an overview of the SEFA tool, demonstrate how to use the tool and provide case studies on sites where the tool has been used. Opportunities will be provided throughout the seminar for participants to submit questions and observations regarding the SEFA tool. For more information and to register, see .

The Use of Passive Samplers to Monitor Organic Contaminants at Superfund Sediment Sites - August 26, 2013, 2:00PM-4:00PM EDT (18:00-20:00 GMT). Passive samplers are useful new tools for assessing contaminant exposures and evaluating the potential for adverse environmental effects at Superfund sites. Since the 1990s, passive samplers have been used for monitoring contaminant concentrations in the water column, soil and sediment interstitial waters, and air at sites around the world. However, their use in sediments to date has been primarily for research. This webinar will introduce the concepts behind passive sampling, the types of passive samplers currently available to monitor dissolved organic contaminants, and the general methods for deployment and analysis. It will also discuss the potential uses of passive samplers in the different phases of the Superfund process and the advantages and disadvantages of their use. This webinar is based on, and complementary to, the recently released Sediment Assessment and Monitoring Sheet on the use of passive samplers at Superfund sites, published by EPA in December, 2012, and available at For more information and to register, see .

Mercury Contaminated Land Management  State of the Art (NICOLE 2013). Mercury exhibits physical and chemical properties (liquid metal, surface tension, vapor pressure) which make it unique and which make the characterization of mercury contamination at industrial sites a challenge. Its distribution, transport and migration are unlike that for other metals found at industrially contaminated sites. Characterization, fate & transport modeling and management of mercury contaminated sites are challenging due to mercurys unique behavior in the environment. View or download at

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 .
