Presented to Bridget R. Scanlon

Phoenix, Arizona, USA 24 September 2019

Hydrogeology Division The Geological Society of America Bridget R. Scanlon

Bridget Scanlon, a senior research scientist at the Bureau of Economic Geology, The University of at Austin, received her B.S. in geology from Trinity College (1980), her M.S. in geology from the (1983), and her Ph.D. in geology from the University of (1985). Currently leading the Sustainable Water Resources Program at the Bureau, Bridget’s areas of expertise include evaluation of the impact of climate variability and land use change on groundwater resources; application of numerical models for simulating variably saturated flow and transport; and assessment of natural and anthropogenic contamination of , including arsenic and nitrate. Among the many awards and honors Bridget has received are the Bureau of Economic Geology Publication Award for exemplary publication of scientific or economic impact (2009); the Joseph C. Walter Jr. Excellence Award, Jackson School of Geosciences (2008); the Geological Society of America Birdsall- Dreiss Distinguished Lecturer (2007); the Conservation Award, Barton Springs Edwards Conservation District (2000, 2004); the George F. Pirtle Award, Department of Geology, (1984); and the Mining and Mineral Resources Research Fellowship, University of Alabama (1982–1983). She is a fellow of the Geological Society of America and of the American Geophysical Union, and she has served on many committees and in many editorial positions. O.E. MEINZER AWARD

I am delighted to introduce Bridget Scanlon as the recipient of the 2019 O.E. Meinzer Award. Bridget’s work truly knows no boundaries. She has conducted research in Europe, North America, Africa, and Asia, on topics ranging from karst hydrology to vadose- zone hydrology to groundwater management, at scales from soil ped to sub-continental. Bridget’s selection for the Meinzer Award is based on four highly cited papers representative of her scope of work. To quote Jack Sharp, one of Bridget’s nominators, she has established herself as “the leading global expert on .” Scanlon, Healy, and Cook (2002, Choosing appropriate techniques for quantifying groundwater recharge, Journal) and Scanlon et al. (2006, Global synthesis of groundwater recharge in semiarid and arid regions, Hydrological Processes) thoroughly documented how recharge varies temporally and spatially in different geologic, climatic, and land-use settings. Lenny Konikow, another of Bridget’s nominators, noted that the second paper “laid the groundwork for later global analyses based on climate modeling and remote sensing data.” Scanlon et al. (2012, Groundwater depletion and sustainability of irrigation in the US High Plains and Central Valley, Proceedings of the National Academy of Sciences) integrated intensive water-level measurements with numerical modeling and GRACE satellite data to assess long-term agricultural pumping from two major U.S. aquifers. Nicot and Scanlon (2012, Water use for shale-gas production in Texas, U.S., Environmental Science & Technology) was among the first studies to quantify water use for , which is increasingly important in U.S. energy production and is likely to become significant in other countries such as China. These latter two papers show Bridget’s increasing focus on considerations of sustainability under climatic and demographic pressures. In summary, Bridget’s contributions to science and society have been sustained, innovative, and important, and she is clearly worthy of joining the distinguished group of Meinzer awardees. —Alan E.
