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.ora OP http://clu-in.ora/live . Conducting Contamination Assessment at Drycleaning Sites - June 8, 2011, 1:00PM-3:30PM EDT (17:00-19:30 GMT). The State Coalition for Remediation of Drycleaners (SCRD) is a forum of state environmental agencies designed to exchange information and facilitate discussion of drycleaner remediation issues. In this training, SCRD members will present information from a recently updated guidance document on conducting contamination assessment work at drycleaning sites. Salient aspects of this document will be presented, including: an overview of the drycleaning process, chemicals used, waste generation and management practices in the drycleaning industry, site reconnaissance, identifying sampling locations and environmental assessment technologies applied to drycleaning facilities. The guidance and internet seminar will help state regulators and practitioners identify likely areas of contamination and more effectively implement investigation approaches at current and former drycleaner facilities.

ITRC Project Risk Management for Site Remediation - June 23, 2011, 11:00AM-1:15PM EDT (15:00-17:15 GMT). Remediation Risk Management (RRM) is a course of action through which all risks related to the remediation processes (site investigations, remedy selection, execution, and completion) are holistically addressed in order to maximize the certainty in the cleanup process to protect human health and the environment. Remediation decisions to achieve such a goal should be made based on threshold criteria on human health and ecological risks, while considering all the other potential project risks.Through this training course and associated ITRC Technical and Regulatory Guidance Document: Project Risk Management for Site Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that can help the site remediation practitioner anticipate, plan for, and mitigate many of the most common obstacles to a successful site remediation project. Examples of project risks include remediation technology feasibility risks; remedy selection risks; remedy construction, operation and monitoring risks; remedy performance and operations risks; environmental impacts of systems during their operation; worker safety risk, human health and ecological impacts due to remedy operation; as well as costs and schedules risks including funding and contracting issues.

Lessons Learned in Detecting, Monitoring, Modeling and Remediating Radioactive Ground-Water Contamination. Brookhaven National Laboratory (BNL) is a multi-discipline Department of Energy (DOE) research institute that has been in operation since 1947. Historical operations included running accelerators, nuclear research reactors, and other large complex equipment. Some of these operations caused groundwater contamination. This report discusses the tritium plume from the TechDirect: June 1, 2011 2 of 6 clu-in.ora/newsletters ------- High Flux Beam Reactor and several strontium plumes from past operations at the Brookhaven Graphite Research Reactor, their discovery through monitoring, and their treatment.The tritium plume discovery led to public outrage; characterization, design, and implementation of a treatment system within 60 days; and eventual dismissal of Associated Universities Incorporated from the management of BNL despite the small health risk to employees or the public. Management of the strontium plume included a major alteration to the original regulatory cleanup agreement when field data showed the preferred alternative to be economically impractical. The report documents activities used to manage these contamination issues through source control, monitoring, modeling, plume and risk management, and communications. The lessons learned from these cleanup projects have altered the stewardship culture and methods of performing research, communicating with the public, and conducting work at BNL. These valuable lessons are highlighted in this report (April 2011, 105 pages). View or download at http://www.nrc.aov/readina-rm/doc-coiiections/nureas/contract/cr7029/cr7029.pdf. Technology News and Trends (EPA 542-N-11-002). This issue highlights passive treatment systems (PTSs) used to treat mining influenced water (MIW) at former or current hard rock mines. Each PTS uses a biochemical reactor (BCR) supported by remediation polishing technologies such as aerobic wetlands or limestone beds. As passive systems, these technologies rely on natural hydraulic gradients (and in some cases renewable energy sources) to transfer impacted water from mine adits and seeps to the ground-surface treatment cells (May 2011, 6 pages).

The California Department of Toxic Substances Control has issued the fifth document developed as part of its proven technologies and remedies (PT&R) initiative. The guidance addresses the overall cleanup process for various types of metal finishing facilities. The document streamlines the cleanup process by applying previously identified proven technologies for cleanup of metals and VOCs in soil. The guidance identifies likely cleanup technologies for remediating hexavalentchromium and VOCs in groundwater (May 2011, 1 39 pages).

New Documents on EUGRIS, the platform for European contaminated soil and water information. More than 39 resources, events, projects and news items were added to EUGRIS in April 1-May 24, 2011. These can be viewed at http://www.euaris.info/whatsnew.asp. Then select the appropriate month and year for the updates in which you are interested. The following resource was posted on EUGRIS: Applying Sustainable Development Principles to Contaminated Land Management Using the SuRF-UK Framework (2011). In the past decade, management of historically contaminated land has largely been based on prevention of unacceptable risks to human health and the environment, to ensure a site is fit for use. More recently, interest has been shown in including sustainability as a decision-making criterion. Sustainability concerns include the environmental, social, and economic consequences of risk management activities themselves, and also the opportunities for wider benefit beyond achievement of risk-reduction goals alone. In the UK, this interest has led to the formation of a multi-stakeholder initiative, the UK Sustainable Remediation Forum (SuRF-UK). This article presents a framework for assessing sustainable remediation; describes how it links with the relevant regulatory guidance; reviews the factors considered in sustainability; and the appraisal tools that have been applied to evaluate the wider benefits and impacts of land remediation.

Explore a subset of the publicly-available simulation and data analysis tools that can be used alone or in combination to answer questions such as: Will source remediation meet site goals? What will happen if no action is taken? Should I combine source and plume remediation? What is the remediation timeframe? What is a reasonable remediation objective? The model discussion will focus on the unique features of selected models and how those features can support strategy development. Emphasis will be on REMChlor, a newly released tool that simulates both source and plume remediation. By providing the ability to simulate sites where conditions change in space and time, REMChlor can provide information "equivalent" to the types of output from more sophisticated numerical models.
