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 http://clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://clu-in.org/training/accommodation.cfm. CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders. For more information and to view upcoming live offerings, please visit http://clu-in.org/live/. For a complete list of RSS feeds available on CLU-IN, please visit http://clu-in.org/rss/about/.

Audio for "Adverse Outcome Pathways: Session I - Introduction to the Adverse Outcome Pathway Framework," Oct 11, 2017
The NIEHS Superfund Research Program (SRP) is hosting a seminar series focused on adverse outcome pathways (AOPs), which are structured ways to represent biological events leading to adverse health effects. In the first session, U.S. Environmental Protection Agency (EPA) staff will provide an introduction and overview of AOPs and discuss the AOP Knowledgebase, which is designed to house descriptions of the biological mechanisms underlying chemical toxicity in a structured manner...
Audio for "Phytoremediation and PhytoForensics: Mother Nature can Detect and Mitigate Pollutants...with Elegance," Oct 10, 2017
Phytoremediation is the field of looking to use plants to mitigate environmental pollutants and human exposures. As plants are efficient, key components in local and global water, carbon and energy cycles, they can influence pollutant transport and availability in many different ways. In this presentation, methods of using plants to prevent human exposure to pollutants will be presented and discussed so share fundamental concepts and case studies of applications...
Slides for "Issues and Options in Human Health Risk Assessment - A Resource When Alternatives to Default Parameters and Scenarios are Proposed," Oct 5, 2017
Many state and local regulatory agencies responsible for the cleanup of chemicals released to the environment have adopted regulations, guidance and policies that define default approaches, scenarios, and parameters as a starting point for risk assessment and the development of risk-based screening values...

Slides for "Use and Measurement of Mass Flux and Mass Discharge," Sep 28, 2017
Most decisions at groundwater contamination sites are driven by measurements of contaminant concentration -- snapshots of contaminant concentrations that may appear to be relatively stable or show notable changes over time. Decisions can be improved by considering mass flux and mass discharge...

Slides for "Integrated DNAPL Site Characterization," Sep 26, 2017
Sites contaminated with dense nonaqueous phase liquids (DNAPLs) and DNAPL mixtures present significant environmental challenges. Despite the decades spent on characterizing and attempting to remediate DNAPL sites, substantial risk remains...

Audio for "ERTP Presents...Soil Sampling and Analysis for Volatile Organic Compounds (VOCs)," Sep 21, 2017
Careful there! Precise characterization of volatile organic compounds (VOCs) in soil is often critical since decisions for remediation are based on analytical measurement. Unfortunately, the acts of collecting and storing soil can subject soils to numerous variables that can alter VOC concentrations. These variables may enhance volatilization, biodegradation, and loss of VOCs in the sample...
Slides for "Integrated DNAPL Site Strategy," Sep 19, 2017
Sites contaminated by chlorinated solvents present a daunting environmental challenge, especially at sites with dense nonaqueous phase liquid (DNAPL) still present. Restoring sites contaminated by chlorinated solvents to typical regulatory criteria (low parts-per-billion concentrations) within a generation (~20 years) has proven exceptionally difficult, although there have been successes...
