The Utah Water Science Center (UWSC) of the U.S. Geological Survey (USGS) is offering a funding opportunity to a CESU partner that has the ability to conduct research on the application of environmental tracers to water resources investigations in Utah and surrounding states including the Great Basin and Upper Colorado River Basin. UWSC primarily conducts research and operates monitoring networks investigating groundwater and surface-water resources in Utah and in adjoining groundwater and surface-water basins. Current research projects and networks include (but are not limited to) Great Salt Lake geochemistry and hydrodynamics, regional groundwater assessments, groundwater and surface-water quality, salinity fate and transport in Upper Colorado River Basin, groundwater discharge to streams in the UCRB, geochemistry and groundwater flow in geothermal systems, Great Basin groundwater availability, numerical ground- and surface-water modeling, methane fate and transport in streams and groundwater-surface water interaction. For more information about UWSC, refer to http://ut.water.usgs.gov/. For a successful cooperative agreement, the CESU partner must have complementary research interests and be able to address these and other potential research topics.
