   abstract: "Fred's current projects include investigating potential changes in\
     \ groundwater recharge under projected climate change in the Colorado River\
     \ basin and understanding the potential for uranium mining effects on regional\
     \ water resources in the Grand Canyon area.Prior to joining the USGS, Fred was\
     \ a post-doctoral researcher with the Ecosystems Research Division of USEPA\u2019\
     s ORD from 2004 through mid-2006, working with Dr. James W. Weaver on issues\
     \ related to soil vapor intrusion, particularly from leaking underground storage\
     \ tanks.  Fred joined EPA after completion of his doctoral degree in Environmental\
     \ Engineering at the University of Virginia in 2003, where he worked with Dr.\
     \ James A. Smith on the response of volatile organic compound (VOC) vapors in\
     \ the unsaturated zone to natural barometric pressure fluctuations (barometric\
