DNAPLs - Biological Remediation Processes: Archive of Jan 25, 2006 Seminar

This seminar is the fourth in a series sponsored by the NIEHS Superfund Basic Research Program to present current research on DNAPLs contaminated sites. Dr. Jim Field, of the University of Arizona, will summarize a comprehensive literature review on the microbial degradation of chlorinated solvents. Running time is 2 hours.

In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones: Archive of May 24, 2011 Seminar

Treatment of dissolved-phase chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). Running time is 2.25 hours.

MTBE and TBA Cleanup-New Research Perspectives: Archive of Jun 24, 2010 Seminar

The UC Davis Superfund Research Program team has isolated a robust, naturally occurring microorganism, Methylibium petroleiphilum PM1, determined its genome sequence and developed a rapid, real-time PCR-based bioassay that can be used to supplement classical monitoring technologies at sites contaminated with methyl tertiary butyl ether (MTBE) and tertiary butyl alcohol (TBA). Quantitative spatial and temporal enumeration of strain PM1 correlates with MTBE and TBA contamination and provides evidence for bioremediation potential. Running time is 1.5 hours.

Wyoming Bioremediation: Produced by U.S. EPA Environmental Response Team

Wyoming Bioremediation: Produced by U.S. EPA Environmental Response Team Bioremediation, a procedure that is widely used in the petroleum industry is being used to clean the petroleum-contaminated soil a 25-acre abandoned refinery near the town of Lovell, Wyoming. The Lovell site is in its third year of treatment. Periodic testing is done to ensure that petroleum contamination levels continue to decrease and that the microorganism populations remain healthy and active. Running time is 8 minutes.

DCE/VC Stall Tool
U.S. Navy, Naval Facilities Engineering Command, Environmental Restoration Technology Transfer, Multimedia Training Tools Website, 19 pages, 2011

At some sites, conditions for complete reductive dechlorination of PCE or TCE to ethene are not present, and degradation stalls at DCE and/or VC. Three basic requirements must be met to form a complete reductive dechlorination pathway: sufficient electron donor (a fermentable carbon source), appropriate redox potential (strongly reducing conditions) in the aquifer, and microbial communities capable of complete dechlorination of PCE to ethene. This tool provides RPMs with the information necessary to recognize DCE and/or VC stall and explores its biological and/or environmental causes, along with potential solutions.

Innovative Treatment Technologies Course
CERCLA Education Center (CEC).

3-Day Course or 1-Day short course. The in-depth, three-day course offered by the CERCLA Education Center (CEC) provides information about technical, financial, and practical factors to be considered when determining the appropriateness of innovative treatment technologies for application in various cleanup projects. The one-day course provides a comprehensive overview of a number of innovative technologies, including bioremediation (various types), soil vapor extraction enhancements, thermal desorption, soil washing, air sparging, passive treatment walls, base-catalyzed dechlorination, surfactant flushing, and thermally enhanced extraction. Visit the TRAINING EXCHANGE web site for schedules and locations.

National Groundwater Association Events—Education

The National Groundwater Association (NGWA) hosts a variety of conferences annually in addition to the annual Ground Water Expo, Ground Water Summit, short courses, and numerous Webinars and brown bag sessions. In addition, NGWA offers numerous customized training courses.
