In Situ Approaches for Measuring Biodegradation Potential and Rates in Subsurface EnvironmentsThe U.S. Geological Survey (USGS) is sponsoring the special session In Situ Approaches for Measuring Biodegradation Potential and Rates in Subsurface Environments at the 2008 Joint Annual Meeting, Houston, Texas, on October 5-9, 2008. The session will feature current research on methods and approachers to determining the the rate contaminants in the subsurface biodegrade. Session DescriptionThe conveners expect this session to include an interdisciplinary mix of hydrogeologists, geochemists, and microbiologists who are using a variety of experimental methodologies to interrogate the subsurface to study biogeochemical reactions of interest. The approaches used might include in situ microcosms, tracer and reactive constituent injection tests, or in situ reactive barriers in a variety of hydrogeologic environments, including pristine or contaminated aquifer, wetlands, or near-stream discharge/recharge zones. They expect studies that incorporate measurements of a variety of reaction footprints including compound disappearance, production of signature metabolites, consumption of electron acceptors, reactions on solid surfaces, and changes in composition or function of microbial populations. The conveners expect presentations that use novel applications of stable isotope probing or molecular methods and that integrate microbiological and geochemical data in order to document biodegradation reactions. In addition the conveners are especially interested in papers that use these in situ approaches to estimate biodegradation rates. The session is hosted by Geological Society of America (GSA) Hydrogeology Division and Gulf Coast Association of Geological Societies. USGS Presentations
