The U.S. Geological Survey (USGS) is currently expanding its strategy for international water resources engagements to be more strategic, with the goal of improving our scientific understanding of the hydrosphere. The USGS currently works with several Latin American countries on groundwater resources studies. For example, USGS is working jointly with Costa Rica’s Ministry of Environment and Energy (MINAE) on a National Groundwater Exploration and Assessment Project, combining remote sensing with climatologic, geologic, hydrologic, and geophysical data for identifying areas of high potential for groundwater development. Along the U.S.-Mexico border, the USGS is working with the International Boundary and Water Commission (IBWC) and the Comisión Nacional del Agua (CONAGUA) on the Transboundary Aquifer Assessment Program (TAAP) including the Hueco Bolson and Mesilla Basin in Texas and New Mexico, and the Santa Cruz and San Pedro aquifers in Arizona. In Bolivia, the USGS and Texas Tech University are studying groundwater in the Tolomosa Basin in the Tarija Department with Universidad Católica Boliviana, and UCB's connections to Cooperativa de Sistema de Agua y Alcantarillado Tarija (COSAALT), Servicio Nacional de Meteorologia e Hidrologia (SENHAMI), and Deutsche Gesellschaft fur Internationale Zusammenarbeit (GIZ). Overall, the USGS is developing an integrated global approach to sustainable groundwater development and technical capacity building.
