TAAP Act

The TAAP Act reauthorizes the U.S. program assessing shared aquifers between the U.S. and Mexico. It adjusts which states receive priority for aquifer studies (adding Arizona while excluding a specific Yuma basin area), reduces annual funding from $50 million to $1.5 million for fiscal years 2026-2033, and updates the program’s expiration date to align with this new law. The bill directly affects U.S. states (New Mexico, Texas, Arizona) and Mexican water management entities by modifying federal funding and assessment priorities for transboundary groundwater resources.
