Shortly after graduating from the University of Illinois in 1976,  I bagan working for the USGS, WRD helping characterize the low-level radioactive waste site at Sheffield, Illinois.  After a few years working at Sheffield and on Strip Mine Tailings reclaimation the timing seemed right for a move from Illinois.  I transferred to Madison, Wisconsin in 1981 and worked on a variety of Water Resources Investigations and several more landfill contamination studies.  In 1989, the issue of radioactive waste disposal again caught my career and I transfered to Denver to join the Yucca Mountain Project Branch.  Since joining the Yucca Mountain Project I have been a Principal Investigator of saturated zone hydrochemistry and unsaturated zone gas phase circulation and hydrochemistry.


My entire career has been spent in the Water Resources Division of the U.S. Geological Survey.  The summaries below describe my primary duties during different stages of my career. From 1997 to present                           GS-1315-13 Hydrologist U.S. Geological Survey, WRD, Yucca Mountain Project Branch Current position- Principal Investigator of Saturated-Zone Hydrochemistry Studies within the Yucca Mountain Site Characterization Project.   General duties include all administrative, budgetary, and supervisory matters, as well as the testing design and sampling methodology for assessing saturated -zone flow in the Yucca Mountain area.   Specific duties are to collect and analyze ground-water chemistry data to determine the direction and rate of saturated-zone flow as it pertains to radionuclide transport from the proposed repository. From 1994 to 1997                              GS-1315-13 Hydrologist U.S. Geological Survey, WRD, Yucca Mountain Project Branch My position was as Principal Investigator of Unsaturated-Zone Gas-Phase Circulation and Unsaturated-Zone Hydrochemistry and Perched Water, within the Yucca Mountain Site Characterization Project.  Specific duties were to collect and analyze data on down hole pneumatic pressure, whole gas chemistry, and isotopic chemistry to assess the air permeability of the hydrogeologic units, travel pathways, and relative ages of gas and water vapor in the unsaturated zone. From 1989 to 1994                              GS-1315-12 Hydrologist U.S. Geological Survey, WRD, Yucca Mountain Project Branch From April, 1990 to April, 1991, I served as acting Principal Investigator, and from 1991 to 1994 as Assistant Principal Investigator for the Saturated-Zone Fractured Rock Hydrology Project, within the Yucca Mountain Site Characterization Project.  My duties included participation in all administrative, budgetary, and supervisory matters, as well as the design and conduct of scientific investigations to determine the type of flow, nature of hydraulic boundaries, bulk aquifer properties, solute transport properties, and the hydraulic influence of faults and fracture zones.   I was also co-Principal Investigator of a cooperative study with scientists from Atomic Energy of Canada Limited and Lawrence Berkeley Laboratory to research the solute transport and hydraulic properties of fractured granite at Canada’s Underground Research Lab, near Pinewa, and at a multiple well site near Raymond Quarry in California. From 1981 to 1989                              GS-1315-11 Hydrologist U.S. Geological Survey, WRD, Wisconsin District My duties were to manage and conduct ground-water resource and contamination studies.  These activities included the preparation and review of project proposals, work plans and schedules, monitoring project funds to remain within budget, and the collection and interpretation of geologic, hydraulic, and chemical data.   My duties also included the preparation of technical reports, summarizing the results of studies, and representing the U.S.G.S. at meetings with cooperators, government agencies, and private and professional organizations. From 1976 to 1981                              GS-1315-9 Hydrologist U.S. Geological Survey, WRD, Illinois District I worked as a team member on the hydrologic study of the Sheffield low-level radioactive waste site in northern Illinois.  Duties included well installation, water-level data collection, conduct of aquifer tests, collection of water chemistry samples, and analysis of hydraulic data.   I was project chief of a study describing ground-water chemistry, water level fluctuations, and ground-water flow paths in strip mined land undergoing reclamation by sewage-sludge irrigation.   I also was project chief of a study to determine the amount of leakage from 4 sewage sludge storage basins in strip mine spoil in western Illinois.
