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.

Audio for "Borehole Geophysics Applied to Bedrock Hydrogeologic Evaluations," Oct 18, 2018
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. In addition, borehole tools commonly used in shallow oil/gas well abandonment are presented. This is part of a geophysics webinar series:Environmental Geophysics Applied to Site Characterization, Plume Mapping, and Remediation MonitoringBorehole Geophysics Applied to Bedrock Hydrogeologic EvaluationsGeophysical Method Selection: Matching Study Goals, Method Capabilities and Limitations, and Site ConditionsThis webinar is a result of Recommendation 9 of EPA?s Superfund Task Force, which encourages the Superfund program to ?utilize state-of-the-art technologies to expedite cleanup.? Actions under this recommendation include expanding the use of new site characterization and remediation technologies and approaches to address contaminated sites. https://www.epa.gov/superfund/superfund-task-force-public-participation-opportunities#webinar To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/tio/BoreholeGeophysics_101818/
