ITRC Green & Sustainable Remediation - January 6, 2015, 1:00PM-3:15PM EST (18:00-20:15 GMT). Many state and federal agencies are just beginning to assess and apply green and sustainable remediation (GSR) into their regulatory programs. This training provides background on GSR concepts, a scalable and flexible framework and metrics, and tools and resources to conduct GSR evaluations on remedial projects. The training is based on the ITRC's Technical & Regulatory Guidance Document: Green and Sustainable Remediation: A Practical Framework (GSR-2, 2011) as well as ITRC's Overview Document, Green and Sustainable Remediation: State of the Science and Practice (GSR-1, 2011). Beyond basic GSR principles and definitions, participants will learn the potential benefits of incorporating GSR into their projects; when and how to incorporate GSR within a project's life cycle; and how to perform a GSR evaluation using appropriate tools. In addition, a variety of case studies will demonstrate the application of GSR and the results. The training course provides an important primer for both organizations initiating GSR programs as well as those organizations seeking to incorporate GSR considerations into existing regulatory guidance.

ITRC LNAPL Training Parts 1, 2, and 3 - January 8, 15, 22. 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 .

SERDP & ESTCP Webinar Series: DNAPL Source Zone Management Approaches, January 8, 12:00PM EST (17:00PM GMT).

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - January 13, 2015, 1:00PM-3:15PM EST (18:00-20:15 GMT). Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants. Petroleum vapor intrusion (PVI) is a subset of VI and is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. The ITRC Technical and Regulatory Guidance Web-Based Document, Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI-1, 2014) and this associated Internet-based training provides regulators and practitioners with consensus information based on empirical data and recent research to support PVI decision making under different regulatory frameworks. The PVI assessment strategy described in this guidance document enables confident decision making that protects human health for various types of petroleum sites and multiple PHC compounds. This guidance provides a comprehensive methodology for screening, investigating, and managing potential PVI sites and is intended to promote the efficient use of resources and increase confidence in decision making when evaluating the potential for vapor intrusion at petroleum-contaminated sites. By using the ITRC guidance document, the vapor intrusion pathway can be eliminated from further investigation at many sites where soil or groundwater is contaminated with petroleum hydrocarbons or where LNAPL is present.

For more information and to register, see http://clu-in.org/live.

ITRC Soil Sampling and Decision Making Using Incremental Sampling Methodology Parts 1 and 2 - February 3 and 5, 2015. This 2-part training course along with ITRC's Web-based Incremental Sampling Methodology Technical and Regulatory Guidance Document (ISM-1, 2012) is intended to assist regulators and practitioners with understanding the fundamental concepts of soil/contaminant heterogeneity, representative sampling, sampling/laboratory error and how ISM addresses these concepts. Through this training course you should learn: basic principles to improve soil sampling results, systematic planning steps important to ISM, how to determine ISM Decision Units (DU), the answers to common questions about ISM sampling design and data analysis, methods to collect and analyze ISM soil samples, the impact of laboratory processing on soil samples, and how to evaluate ISM data and make decisions. In addition this ISM training and guidance provides insight on when and how to apply ISM at a contaminated site, and will aid in developing or reviewing project documents incorporating ISM (e.g., work plans, sampling plans, reports). For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live.

The 3D Elevation Program Initiative - A Call for Action. The 3D Elevation Program (3DEP) initiative is accelerating the rate of three-dimensional (3D) elevation data collection in response to a call for action to address a wide range of urgent needs nationwide. The National Elevation Dataset (NED) will be completely refreshed with new elevation data products and services. The call for action requires broad support from a large partnership community committed to the achievement of national 3D elevation data coverage. The initiative is being led by the U.S. Geological Survey (USGS) and includes many partners-Federal agencies and State, Tribal, and local governments-who will work together to build on existing programs to complete the national collection of 3D elevation data in 8 years. Private sector firms, under contract to the Government, will continue to collect the data and provide essential technology solutions for the Government to manage and deliver these data and services. As proposed, the 3DEP effort would begin providing products and services to partners and the public in 2015 (September 2014, 48 pages). View or download at http://pubs.usgs.gov/circ/1399/.

Illustrated Handbook of LNAPL Transport and Fate in the Subsurface. The LNAPL illustrated handbook presents best-practice guidance for the assessment and remediation of light non-aqueous phase liquids (LNAPLs) in the subsurface. LNAPLs notably include fuels and oils, for example petrol (gasoline), diesel and heating oils, and are amongst the most commonly encountered organic contaminants in the subsurface environment due to their ubiquitous use, accidental release and, perhaps, poor (historical) disposal. Central to the handbook and the management of risks posed is the development of conceptual models of LNAPL behavior in common hydrogeological systems. The LNAPL illustrated handbook provides a blend of technical detail and real world conceptualization of the LNAPL problem and appropriate methods to investigate and manage it. The handbook also facilitates access to a wealth of detailed research, guidance and case study literature within the various topics covered. It will be useful to the practitioner and research communities, and also provide a valuable educational resource to others having a less direct interest or specialized knowledge.

Financing Mechanisms for Addressing Remediation of Site Contamination (2014, World Bank). Industrial and commercial facilities provide great economic benefit to communities throughout the world. Unfortunately, many industries use or have used practices and materials which have proven toxic to the environment and to those who live and work near contaminated sites. The definition and degree of contamination varies at national and regional levels of government, but leaders throughout the world now recognize the hazard that contaminated industrial and service sites present to the wellbeing of their communities and seek innovative ways to finance the remediation of these challenging sites. Industrial contamination can have a severe, direct impact on adjacent communities. The cleanup and redevelopment of a so-called ?brownfield? can ?improve a community?s economy, provide an opportunity for habitat restoration, and create public space.? Cleanup and redevelopment of brownfields can be an effective economic development strategy, with benefits seen in two timeframes. First, there is an immediate and one-time capital expenditure for cleanup activities, infrastructure, and construction. The initial investment generates tax revenues, temporary family-wage jobs, and indirect economic benefits within the community. Secondly, there is a long-term economic impact from remediation projects in the form of higher property values, long-term tax revenues, and the attraction of external capital to the community by tenants of the revitalized property. The economic benefit of contaminated site redevelopment is perhaps most clearly illustrated by permanent job creation from the restored properties. The deleterious effects of industrial contamination across all facets of a community typically provide a strong incentive for leaders to seek financing mechanisms that make site remediation possible.
