ITRC Groundwater Statistics for Environmental Project Managers - February 12, 2015, 1:00PM-3:15PM EST (18:00-20:15 GMT). Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training specifically for environmental project managers who review or use statistical calculations for reports, who make recommendations or decisions based on statistics, or who need to demonstrate compliance for groundwater projects. The training class will encourage and support project managers and others who are not statisticians to: use the ITRC Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make better decisions for projects; apply key aspects of the statistical approach to groundwater data; and answer common questions on background, compliance, trend analysis, and monitoring optimization. ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation, and communication of groundwater statistical methods and should lead to greater confidence and transparency in the use of groundwater statistics for site management. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live.

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - February 17, 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.

ITRC Environmental Molecular Diagnostics: New Tools for Better Decisions - February 19, 2015, 1:00PM-3:15PM EST (18:00-20:15 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.

Adaptation of Superfund Cleanup to Climate Change - April 1, 2015, 2:00PM-4:00PM EDT (18:00-20:00 GMT). This webinar will provide an overview of climate change vulnerability analyses and adaptation at contaminated sites. In some circumstances climate change may result in vulnerabilities in the protectiveness of contaminated site remedies. The course focuses on how such a vulnerability may be better understood and on the means of achieving increased remedy resilience through adaptation measures. The course builds upon a general understanding of the Superfund process, but is relevant to most cleanup programs. By taking the course, participants will gain a better understanding of the following topics: overview of Superfund-specific climate change action plan; framing site-specific analyses to understand remedy vulnerabilities throughout the life of a remedy, and of adaptation measures that may increase remedy resilience; tapping existing and relevant information resources when evaluating the potential impacts of climate at Superfund sites; and regional case studies of Superfund sites that have been impacted by a major weather event.

A Review of Green and Sustainable Remediation (GSR) Practices at NAVFAC Environmental Restoration Sites. A review was conducted to assess the application of GSR metrics at 60 Navy and Marine Corps sites nationwide. The case study information obtained was used to identify and categorize best management practices (BMPs) and their potential impact on the remedy footprint and to track overall trends in the adoption of GSR practices across the Naval Facilities Engineering Command (NAVFAC). Among the sites where a remedy was selected, the results showed 84% of GSR evaluations resulted in the selection of the lowest footprint remedy and 69% resulted in the selection of the lowest cost remedy. The results of the review suggest that GSR evaluations are leading to more sustainable and cost-effective remedies (July 2014, 213 pages). View or download at http://clu-in.org/EXWC-EV-1439.
