Key Points

This bill continues a scientific program that studies underground water sources, called aquifers, shared by the United States and Mexico. It extends the program through the year 2036.
The program helps officials understand how much water is available along the border. This information is used to manage water fairly and plan for future needs in dry regions.
The new version of the law adds Arizona to the list of priority areas for study. Previously, the program focused mostly on water sources in New Mexico and Texas.
By gathering data on these shared water supplies, the program helps local communities in border states prepare for droughts and ensure they have enough water for homes and farms.
