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

In this webinar we will explore the definition, development, dynamics, and characteristics of "High Performing Teams". There are multiple developmental stages that teams progress through to become high performing; many team members are unaware of these stages. We will examine the behavior and characteristics of the team in these stages as well as the leadership required to maximize team performance in each stage...

Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013, http://www.itrcweb...

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...

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...

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...

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...

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...

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...

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...

The sediments underlying many of our nation?s major waterways are contaminated with toxic pollutants from past industrial activities. Cleaning up contaminated sediments is expensive and technically-challenging. Sediment sites are unique, complex, and require a multidisciplinary approach and often project managers lack sediments experience...
