Researchers from the U.S. and Mexico have begun studying the aquifers, known as "transboundary aquifers," that straddle the two countries in order to gain a unified picture of the underlying groundwater systems and initiate planning for the future. A final report on the San Pedro Aquifer, which lies on the border of Arizona and Mexico's state of Sonora, has been issued with a report on the Santa Cruz Aquifer to be published early next year.
