T60 top Transport and Remediation of Organic Compounds in the Saturated Zone
GSA Hydrogeology Division
Thomas B. Boving, University of Rhode Island, Kingston, RI; John E. McCray, Colorado School of Mines, Golden, CO
Transport, fate, and remediation of organic contaminants in groundwater systems has been the focus of intense research over the past decade. This session will focus on recent advances and elucidates the fundamental physics and chemistry associated with these processes. ORAL and POSTER
Hydrogeology; Geochemistry, Organic; Environmental Geoscience
T61 top Springs: Interactions of Physical, Chemical, Biological, and Cultural Systems
GSA Hydrogeology Division
Abe Springer, Northern Arizona University, Flagstaff, AZ; Susan Swanson, Beloit College, Beloit, WI
Springs support immense biological diversity and are important for traditional uses by various cultures. We encourage submissions of recent research into the physical and chemical understanding of springs and the interactions between springs and their dependent biological and cultural systems. ORAL and POSTER
Hydrogeology; Environmental Geoscience; Engineering Geology
T62 top Flow and Biogeochemical Processes at the Interface Between Surface Water and Groundwater
GSA Hydrogeology Division
Donald O. Rosenberry, U.S. Geological Survey, Lakewood, CO; Masaki Hayashi, University of Calgary, Calgary, AB
Research on the interaction between surface water and groundwater will be presented from a broad range of physical settings and scientific disciplines. Topics will include hydrological and biogeochemical processes, measurement methods, and results from mathematical modeling. ORAL
Hydrogeology; Geochemistry, Aqueous; Marine/Coastal Science
T63 top Exploring the Linkages Between the Geochemistry, Biology, and Hydrology of the Hyporheic Zone (Posters)
GSA Hydrogeology Division
Eric W. Peterson, Illinois State University, Normal, IL; Toby Dogwiler, Winona State University, Winona, MN
An interdisciplinary session designed to synthesize and expose concepts of hyporheic zone, focusing on the "exchange flows" that link the geochemistry, biology, and hydrology of the stream with substrate of the forms the hyporheic zone. POSTER
Hydrogeology; Geochemistry, Aqueous; Quaternary Geology/Geomorphology
T64 top How Subsurface Properties Determine Microbial Habitats: The Role of Groundwater Flow and Subsurface Chemistry in Supplying Energy and Nutrients to the Subsurface Biosphere
GSA Hydrogeology Division, International Association of Hydrogeologists/U.S. National Chapter; GSA Geobiology and Geomicrobiology Division
Barbara Bekins, U.S. Geological Survey, Menlo Park, CA; Phillip Bennett, University of Texas, Austin, TX
This session will examine the role of groundwater flow and subsurface chemistry in supplying energy and nutrients to the subsurface biosphere. Microbial habitats both in the terrestrial subsurface and below the seafloor and their relationship to subsurface properties are of interest. ORAL and POSTER
Hydrogeology; Geomicrobiology; Geochemistry, Aqueous
T65 top Evolution and Migration of Brines in Sedimentary Basins
GSA Hydrogeology Division, GSA Sedimentary Geology Division; Society of Economic Geologists; Society for Sedimentary Geology
Alicia M. Wilson, University of South Carolina, Columbia, SC; Benjamin J. Rostron, University of Alberta, Edmonton, AB
Brines hold clues to often complex paleohydrologic and geochemical histories and provide an important approach for studies of long-term transport in sedimentary basins. We seek contributions that explore the geochemical evolution, migration, and distribution of brines in modern and ancient basins from hydrogeologic and geochemical standpoints. ORAL and POSTER
Hydrogeology; Geochemistry, Aqueous; Economic Geology
T66 top Karst Hydrology and Geomorphology in North America Over the Past Half Century: In Honor of Derek Ford and William White
GSA Hydrogeology Division; GSA Quaternary Geology and Geomorphology Division; Karst Waters Institute
Carol M. Wicks, University of Missouri, Columbia, MO; Russell S. Harmon, U.S. Army Research Office, Durham, NC
For 50 years, sustained pioneering work by Derek Ford and Will White has guided North American research in karst hydrology and geomorphology. This session honors their scientific contributions by presenting current research results and new research directions. ORAL and POSTER
Hydrogeology; Quaternary Geology/Geomorphology
T67 top Hydrogeologic Analysis of Glaciated Terrains
GSA Hydrogeology Division; GSA Engineering Geology Division
John J. Quinn, Argonne National Lab, Argonne, IL; M. Jim Hendry, University of Saskatchewan, Saskatoon, SK
Characterizing complex glacial deposits poses a challenge in analyses of groundwater contamination and water resources. Field, lab, and computer techniques to characterize and model the hydrogeology of glaciated terrains are presented. ORAL
Hydrogeology; Quaternary Geology/Geomorphology; Engineering Geology
T68 top Quaternary Stratigraphy and Implications for Water Resources in the Pacific Northwest
U.S. Geological Survey; Washington Water Science Center; GSA Hydrogeology Division
Sue Culton Kahle, U.S. Geological Survey, Tacoma, WA; Christopher P. Konrad, U.S. Geological Survey, Tacoma, WA
Advances in Quaternary stratigraphic knowledge and applied hydrogeology will be shared by participants in order to further the advancement of hydrogeologic sciences related to the Quaternary deposits in the Pacific Northwest. ORAL and POSTER
Hydrogeology; Quaternary Geology/Geomorphology; Environmental Geoscience
T69 top Characterization of Brackish and Saline Aquifer Systems
GSA Hydrogeology Division; U.S. Geological Survey
Norman Grannemann, U.S. Geological Survey, Lansing, MI; Alan Burns, U.S. Geological Survey, Lakewood, CO
This session addresses the hydrogeology of saline and brackish aquifers, the geochemistry of water in those systems, the effects of withdrawing saline water for desalting, and disposal of brine associated with the desalting process. ORAL
Geochemistry, Aqueous; Hydrogeology
