                                S. 1957

       Be it enacted by the Senate and House of Representatives of 
     the United States of America in Congress assembled,

     [SECTION 1. SHORT TITLE.

       [This Act may be cited as the ``United States-Mexico 
     Transboundary Aquifer Assessment Act''.

     [SEC. 2. FINDINGS AND PURPOSE.

       [(a) Findings.--Congress finds that--
       [(1) rapid population growth in the United States-Mexico 
     border region over the last decade has placed major strains 
     on limited water supplies in the region;
       [(2) water quantity and quality issues are likely to be the 
     determining and limiting factors affecting future economic 
     development, population growth, and human health in the 
     border region;
       [(3) increasing use of groundwater resources in the border 
     region by municipal and other water users has raised serious 
     questions concerning the long-term availability of the water 
     supply;
       [(4) cooperation between the United States and Mexico in 
     assessing and understanding transboundary aquifers is 
     necessary for the successful management of shared groundwater 
     resources by State and local authorities in the United States 
     and appropriate authorities in Mexico, including management 
     that avoids conflict between the United States and Mexico;
       [(5) while there have been some studies of binational 
     groundwater resources along the United States-Mexico border, 
     additional data and analyses are needed to develop an 
     accurate understanding of the long-term availability of 
     useable water supplies from transboundary aquifers; and
       [(6) the Border States--
       [(A) are primarily responsible for the management and 
     allocation of groundwater resources within the respective 
     boundaries of the Border States; and
       [(B) should have a cooperative role in the analysis and 
     characterization of transboundary aquifers.
       [(b) Purpose.--The purpose of this Act is to direct the 
     Secretary of the Interior to establish a United States-Mexico 
     transboundary aquifer assessment program to--
       [(1) systematically assess priority transboundary aquifers; 
     and
       [(2) provide the scientific foundation necessary for State 
     and local officials to address pressing water resource 
     challenges in the United States-Mexico border region.
