Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Audio Archives

Since 1998, The Contaminated Site Clean-Up Information (CLU-IN) website has presented Internet Seminars covering a wide variety of technical topics related to hazardous waste characterization, monitoring, and remediation. For each seminar topic, we have selected the highest-quality offering for placement in our archives. Beginning in May 2005, we began offering these archives via podcast, and this feed contains all seminars archived in the last 6 months. For a complete list of seminars archived since 2000 and videos of selected seminars archived since 2012, please visit Our Rehabilitation Act Notice for reasonable accommodation is available at CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders.

Audio for "Connecting the Science to Managing LNAPL Sites a 3 Part Series - Part 1," Jan 8, 2019

Connecting the Science to Managing LNAPL Sites ? 3-Part Series The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you: Build upon your Understanding of LNAPL Behavior in the Subsurface (Part 1) Develop your LNAPL Conceptual Site Model and LNAPL Remedial Goals (Part 2) Select/Implement LNAPL Technologies (Part 3)After this training series, the expectation is that you will have the skills and understanding to use ITRC science-based resources to improve decision making at your LNAPL sites. For regulators and other government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs. It is recommended that participants have a general understanding of hydrogeology and some familiarity with petroleum contaminated sites. The courses will build on your existing LNAPL knowledge and outline the framework for making LNAPL remediation and management decisions. It is expected that participants will attend this 3-part training series in sequence. LNAPL Training Part 1: Understanding LNAPL Behavior in the Subsurface Part 1 teaches how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1: Explains what LNAPL data can tell you about the LNAPL and site conditions Covers how that information is applied to the development of an LNAPL conceptual site model (LCSM) (Part 2) and LNAPL technology selection (Part 3)Relevant and practical examples are used to illustrate key concepts. LNAPL Training Part 2: LNAPL Conceptual Site Models and the LNAPL Decision Process Part 2 teaches participants how to develop an LNAPL conceptual site model (LCSM) and the overall framework for making LNAPL remediation and management decisions. Part 2: Discusses key LNAPL and site data Explains when and why those data may be important Covers how to effectively organize the data into an LCSMPart 2 also discusses how to address LNAPL concerns by selecting appropriate goals and objectives, choosing applicable technologies, and assigning remedial performance metrics and endpoints. LNAPL Training Part 3: Using LNAPL Science, the LCSM, and LNAPL Goals to Select an LNAPL Remedial Technology Part 3 of the training teaches the importance of informed remedial technology selection and appropriate technology application. Part 3: Discusses remedial technology groups Introduces specific and new remedial technologies Reviews the technology selection process, how technologies can be combined to accelerate cleanup, and how the LCSM informs selectionA case study and examples demonstrate the use of these tools for remedial technology selection, implementation, and demonstration of successful remediation. Training participants are encouraged to view the associated ITRC guidance, LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018), prior to attending the class.
