EPA Solicits Innovative Ideas and Technological Solutions for Enbridge Oil Spill.
EPA has developed a voluntary submittal process to allow for faster review of the suggestions being offered and to provide guidance regarding what information would be most useful to the reviewing officials. The information received through this voluntary submittal process will be scrutinized for innovative ideas and technological solutions that are safe for the environment and public health and can be deployed along the Kalamazoo River to help with cleanup. The information submitted will be forwarded to the appropriate reviewing official who will contact submitters, if necessary. For more information or to submit a technical solution, go to the EPA Enbridge Oil Spill web site at http://www.epa.gov/enbridgespill/technology/index.html .

ITRC LNAPL Training Parts 1, 2, and 3 - August 3, 10, and 17, 2010. 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 .

The Charrette: Redevelopment by Design - August 11, 2010, 2:00PM-3:30PM EDT (18:00-19:30 GMT). A Charrette uses pictures and mapping tools to develop innovative, sustainable plans for revitalization. Traditional planning and negotiation efforts can be stymied by the complex issues and divergent perspectives, leaving all parties frustrated. These collaborative workshops help participants visually understand the complexities of land re-use and revitalization. They have made a difference across the country by moving the affected stakeholders from negative approaches to positive plans for the future. This training will help EPA employees explore the use of Charrettes for collaborative redevelopment of Superfund sites. For more information and to register, see http://clu-in.org/live .

Identifying & Evaluating Ecosystem Services at Contaminated Sites Prior to Remediation - August 18, 2010, 3:00PM-4:30PM EDT (19:00-20:30 GMT). Green remediation is the practice of considering all environmental effects of remedy implementation and incorporating options to maximize net environmental benefits of cleanup actions at contaminated sites. One of the core elements of green remediation is land & ecosystems, which promotes ideas of land management and ecosystem protection. There is a growing recognition of the significance of ecosystem services, as well as the dramatic impacts human activities can have on these essential services. Ecosystem services are the benefits that human populations derive from ecosystems. Examples include erosion control, climate regulation, recreational opportunities and raw materials. There is a unique opportunity to mitigate impacts on ecosystem services, which may occur from the remediation of contaminated sites. Learn more about ecosystem services, opportunities to mitigate impacts on ecosystem services at a site level, and much more during this seminar brought to you by Sarah Slack, a NNEMS fellow at the EPA.

PAH and PCB Toxicity and Adaptation - Lessons Learned from Chronically Exposed Wild Populations - August 19, 2010, 2:00PM-4:00PM EDT (18:00-20:00 GMT). This seminar will feature Dr. Mark E. Hahn of Woods Hole Oceanographic Institution and Dr. Richard T. Di Giulio, Director of Duke University's Integrated Toxicology Program. Dr. Hahn will describe research to understand the role of aryl hydrocarbon receptors (AHRs) and AHR variants in the mechanism of resistance to PCBs that has evolved in Atlantic killifish (Fundulus heteroclitus) inhabiting the New Bedford Harbor (MA) superfund site. Other studies that address the role of AHRs as biomarkers of susceptibility and resistance will be discussed. Dr. Di Giulio will describe studies addressing mechanisms underlying the marked resistance to PAH toxicity displayed by a population of Atlantic killifish (Fundulus heteroclitus) inhabiting a PAH contaminated estuary adjacent to the Atlantic Woods Industries Superfund site in Virginia. These studies subsequently motivated additional studies that will be described that examined the unanticipated phenomenon of synergisitc toxicity between certain PAHs. These latter studies included both the killifish and the zebrafish as models. For more information and to register, see http://clu-in.org/live .

Impacts of DNAPL Source Treatment: Experimental and Modeling Assessment of the Benefits of Partial DNAPL Source Removal (EPA 600-R-09-096). When it is not practical or economically feasible to achieve complete DNAPL mass depletion using aggressive remediation techniques, it must be determined if the aggregate benefits of partial DNAPL mass depletion are sufficient to reduce risks to an acceptable level and if the costs associated with this partial depletion are justified by the benefits received. This report summarizes field, lab, and modeling research conducted to address these issues, with the primary objective being the development of a scientifically defensible approach for assessing the long-term environmental impacts (benefits) of DNAPL removal from source zones (September 2009, 172 pages).

EPA Launches a Collaborative Web Site for Integrated Environmental Modeling. The U.S. EPA is launching a new on-line tool for scientific collaboration and knowledge sharing that was built by Purdue University with support from EPA. The Integrated Environmental Modeling Hub (iemHUB) allows environmental researchers to analyze environmental problems and combine environmental models so that a better understanding of the environment can be developed. EPA uses integrated modeling assessments to inform decision making in support of its broad mission of protecting human health and safeguarding the environment. With the website, the agency is providing a state-of-the-art resource to the environmental modeling community. The iemHUB supports the development of integrated models and their use in conducting research and informing the decision making process. The iemHUB is being released by the EPA-supported Community of Practice for Integrated Environmental Modeling (CIEM). The Community of Practice is an informal collaborative organization that was set-up by EPA and other scientists to advance the state of the science and technology related to integrated modeling. View and use at http://www.iemhub.org .
