Light Non-Aqueous Phase Liquids (LNAPLs) Training Courses
The LNAPLs (Light Non-Aqueous Phase Liquids) training courses help users set appropriate LNAPL remedial objectives in the context of a site-specific LNAPL conceptual site model, provide tools to screen 17 LNAPL remedial technologies to identify an optimal LNAPL remedial technology to achieve the objectives, and provide example performance metrics that would be set to gauge remedial effectiveness and demonstrate achievement of the objectives. Natural source zone depletion (NSZD) for LNAPLs is also summarized, including the processes involved, their rates, and potential for long-term progress.
ITRC’s nationwide training courses are unique forums for the exchange of technical and regulatory information related to environmental remediation. Classroom training courses are offered in classroom settings where participants can receive in-person, face-to-face training. ITRC’s multi-day classroom training events include hands-on problem solving to engage the students with real world and site applications. Multi-day classroom training is often provided in conjunction with an ITRC member state.

A sound LNAPL understanding is necessary to effectively characterize and assess LNAPL conditions and potential risks, as well as to evaluate potential remedial technologies or alternatives. Unfortunately, many environmental professionals have a faulty understanding of LNAPL conditions based on outdated paradigms. The ITRC LNAPLs Team is providing Internet-based training to improve the general understanding of LNAPLs. Better understanding leads to better decision making. Additionally, this training provides a necessary technical foundation to foster effective use of the ITRC LNAPLs Team Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009).
Part 1 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.
Over the past few decades, a spectrum of LNAPL remedial technologies have developed that range from conventional pumping or hydraulic recovery systems that address the mobile LNAPL fraction, to a variety of innovative, aggressive, and experimental technologies that address the mobile and residual LNAPL fractions, as well as volatile and soluble LNAPL fractions. Thus, many different LNAPL remedial technologies with differing site and LNAPL applicabilities and capabilities are available to remediate LNAPL releases. This can make selection of a remedial technology daunting and inefficient. To foster informed remedial technology selection and appropriate technology application, the LNAPLs Team developed the ITRC Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009). This document addresses seventeen LNAPL remedial technologies and provides a framework to streamline remedial technology evaluation and selection.
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. The training course also provides an overview of the LNAPL remedial technology selection framework. The framework uses a series of tools to screen the seventeen remedial technologies addressed in the ITRC Technical and Regulatory Guidance document, Evaluating LNAPL Remedial Technologies for Achieving Project Goals (LNAPL-2, 2009) based on site and LNAPL conditions and other important factors.
