ITRC LNAPL Training Parts 1, 2, and 3 - March 5, 7, 14. 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 or .

Hardrock Mining Geochemistry and Hydrology, Workshop 3 - Sampling, Monitoring and Remediation at Mine Sites - March 5, 2013, 1:00PM-3:00PM EST (18:00-20:00 GMT).

ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation - March 12, 2013, 2:00PM-4:15PM EDT (18:00-20:15 GMT). This training, which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation and remediation of biofuels; and select appropriate investigation and remediation strategies. For more information and to register, see or .

Superfund Redevelopment Initiative: Ecological Revitalization of Contaminated Properties - March 19, 2013, 2:00PM-4:00PM EDT (18:00-20:00 GMT). This Superfund Redevelopment Initiative webinar will provide an overview of formerly contaminated properties that have been successfully returned to an ecological land reuse. Participants will learn about the tools and resources that the EPA can provide to assist communities with ecological reuse of contaminated properties. Presenters will discuss cost-effective remedies that support ecological land reuse and how to address risk through remedy design. Stakeholders from the Chemical Commodities Inc. Superfund site in Olathe, Kansas, will present an in-depth case study of their site, which is now a pollinator migration corridor, restored native prairie habitat, walking trail, and teaching tool. Presenters will share lessons learned, community involvement, benefits of ecological reuse at a contaminated property and techniques for demonstrating success.

New CLU-IN Focus Area on High-Resolution Site Characterization (HRSC). HRSC is a new EPA focus area that reflects the state-of-the-science for environmental site characterization. HRSC strategies and technologies use scale-appropriate measurement and data density to delineate contaminant distributions in environmental media with greater certainty, supporting faster and more effective remedy selection, design and implementation. This website provides a description of the general concepts and benefits of HRSC and offers resources including case studies for sites where HRSC has been applied, information on practitioner forums, information on available training, and instructions on accessing available support for understanding and applying HRSC.

New CLU-IN Focus Area on Bioremediation. The new bioremediation focus area provides a general introduction to aerobic, anaerobic, and cometabolic biodegradation mechanisms, as well as guidance, and site specific information. Both in situ and ex situ technologies are addressed. View and use at .

Technology News and Trends (EPA 542-N-13-001). This issue highlights the use of nanotechnologies to chemically reduce chlorinated volatile organic compounds (CVOCs), metals and metalloids such as chromium and arsenic, and persistent organic compounds contaminating groundwater, soil, or sediment. Nanoscale materials typically used for remediation involve nanoscale zero-valent iron (ZVI), bimetallic nanoscale particles, or emulsified zero-valent iron (EZVI). The U.S. EPA's National Risk Management Research Laboratory and other agencies or organizations are researching remediation efficacy as well as fate, transport, and toxicity of these and other nanoscale materials with potential to adsorb or destroy contaminants as part of in situ or ex situ processes (February 2013).
