Bill Overview

Analyzed Economic Effects

2 provisions identified: 2 benefits, 0 costs, 0 mixed.

Arizona added to priority aquifers

If enacted, the program could name Arizona aquifers as priority transboundary aquifers. One area would be excluded: the aquifer under Arizona and Sonora that partly sits in the Yuma groundwater basin named in a June 21, 1984 state order. This would let more Arizona areas be studied under the program.

Funding for border aquifer studies

If enacted, this would authorize $1.5 million each year from 2026 through 2033 for the U.S.–Mexico transboundary aquifer assessment program. The money would be subject to future appropriations. State agencies, universities, and local water authorities could receive funds to study shared groundwater.
