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

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...

At some sites, complex site-specific conditions make it difficult to fully remediate environmental contamination. Both technical and nontechnical challenges can impede remediation and may prevent a site from achieving federal- and state-mandated regulatory cleanup goals within a reasonable time frame. For example, technical challenges may include geologic, hydrogeologic, geochemical, and contaminant-related conditions as well as large-scale or surface conditions...

This presentation introduces the viewer to borehole geophysical tools commonly used in hydrogeologic investigations. These tools include gamma, temperature, conductivity, caliper, borehole video, acoustic and optical televiewers, heat-pulse flowmeter, and borehole deviation. Examples and case studies follow illustrating the usefulness of data obtained through the utilization of these tools, especially when used to design packer tests and multi-level discrete-zone sampling strings...

This is a two-part webinar series featuring presentations delivered at the Spring 2018 FRTR Meeting. The meeting?s goals were to identify and discuss case studies where remediation technologies were successful for a variety of soil and groundwater systems; and to share experiences and lessons learned that contributed to the operation of these successful remediation technologies...

Environmental geophysics investigates the geophysical response to natural and anthropogenic materials, processes, and alterations, which impact human health and ecosystems within the near surface of the earth. This presentation will cover biogeophysics, geophysical characterization and monitoring of contaminant plumes and remediation, groundwater ? surface water interactions, using geophysics for conceptual site model (CSM) development, and online resources soon to be available at epa.gov...

A mishap, as defined by EM 385-1-1, Safety and Health Requirements Manual-USACE-ARMY is any unplanned, undesired event that occurs during the course of work being performed. This includes, accidents, incidents and near misses. Reporting requirements and timelines are specific to the type of incident and are often confused by safety personnel. The result is that many times the required timelines are not met...

Environmental contamination can disrupt life as usual. Community members may feel stress for several reasons, including health and financial concerns. Join this webinar to learn more about stress, how it can affect health, and why environmental contamination can cause it. We?ll offer practical tips and tools for acknowledging stress with community members and helping them cope...

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...
