ITRC LNAPL Training Parts 1, 2, and 3 - October 6, 11, and 13. 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

ITRC Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management - October 20, 2016, 1:00PM-3:15PM EDT (17:00-19:15 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.

Optimization Review Report: Saunders Supply Company Superfund Site Suffolk County, Virginia, EPA Region 3 (EPA 542-R-16-004). The Saunders Supply Company Superfund Site is located in Suffolk County, Virginia, in EPA Region 3, and is a 7-1/3 acre former wood treating plant. The source areas included wastewater ponds, treatment areas, and burn pits located on the Saunders property and were remediated by removing liquids and contaminated soil. Primary contaminants are currently pentachlorophenol (PCP), arsenic, and chromium in groundwater. The site is in the operation and maintenance (O&M) phase and uses a groundwater pump and treat (P&T) system to control migration of the contaminants and remove contaminant mass from the aquifer. An optimization review team was assembled and met with regulatory stakeholders and consultants at the site to observe site conditions, review site data and remediation goals, and discuss the technical aspects of the existing remedy and its performance toward achieving remediation goals. This report summarizes the findings and recommendations of the optimization review team (August 2016, 49 pages). View or download at

Superfund Research Program Research Brief 261: Importance of Young Dissolved Organic Carbon to the Release of Arsenic in Aquifers. Carbon from relatively new sources of organic material on the surface, or young carbon, can stimulate microbial communities deep in aquifers, leading to the release of arsenic into water, according to a recent field study by Columbia University Superfund Research Program (SRP) Center researchers. The researchers found that near-surface sources of organic carbon are central in microbial metabolism, even in aquifers that are far below and separated from the land where carbon is derived.

Holistic Management of Brownfield Regeneration - All Outputs (HOMBRE project). At the heart of HOMBRE is the ambition to create a paradigm shift to Zero Brownfields where Brownfields become areas of opportunity that deliver useful services for society, instead of derelict areas that are considered useless. This ambition will be met by looking at how synergies between different types of services might leverage change where none was possible before. Each Brownfield has its own potential for delivering useful combinations of services and hence new opportunities. Public project outputs are available from
