SEC. 4. ESTABLISHMENT OF PROGRAM.

    (a) In General.--The Secretary, in consultation and cooperation 
with the Border States, the water resources research institutes, Sandia 
National Laboratories, and other appropriate entities in the United 
States and Mexico, shall carry out the United States-Mexico 
transboundary aquifer assessment program to characterize, map, and 
model transboundary groundwater resources along the United States-
Mexico border at a level of detail determined to be appropriate for the 
particular aquifer.
    (b) Objectives.--The objectives of the program are to--
            (1) develop and implement an integrated scientific approach 
        to assess transboundary groundwater resources, including--
                    (A)(i) identifying fresh and saline transboundary 
                aquifers; and
                    (ii) prioritizing the transboundary aquifers for 
                further analysis by assessing--
                            (I) the proximity of the transboundary 
                        aquifer to areas of high population density;
                            (II) the extent to which the transboundary 
                        aquifer is used;
                            (III) the susceptibility of the 
                        transboundary aquifer to contamination; and
                            (IV) any other relevant criteria;
                    (B) evaluating all available data and publications 
                as part of the development of study plans for each 
                priority transboundary aquifer;
                    (C) creating a new, or enhancing an existing, 
                geographic information system database to characterize 
                the spatial and temporal aspects of each priority 
                transboundary aquifer; and
                    (D) using field studies, including support for and 
                expansion of ongoing monitoring and metering efforts, 
                to develop--
                            (i) the additional data necessary to 
                        adequately define aquifer characteristics; and
                            (ii) scientifically sound groundwater flow 
                        models to assist with State and local water 
                        management and administration, including 
                        modeling of relevant groundwater and surface 
                        water interactions;
            (2) expand existing agreements, as appropriate, between the 
        United States Geological Survey, the Border States, the water 
        resources research institutes, and appropriate authorities in 
        the United States and Mexico, to--
                    (A) conduct joint scientific investigations;
                    (B) archive and share relevant data; and
                    (C) carry out any other activities consistent with 
                the program; and
            (3) produce scientific products for each priority 
        transboundary aquifer that--
                    (A) are capable of being broadly distributed; and
                    (B) provide the scientific information needed by 
                water managers and natural resource agencies on both 
                sides of the United States-Mexico border to effectively 
                accomplish the missions of the managers and agencies.
    (c) Designation of Priority Transboundary Aquifers.--
            (1) In general.--For purposes of the program, the Secretary 
        shall designate as priority transboundary aquifers--

                underlying parts of Texas, New Mexico, and Mexico; and
                    (B) the Santa Cruz River Valley aquifers underlying 
                Arizona and Sonora, Mexico.
            (2) Additional aquifers.--The Secretary shall, using the 
        criteria under subsection (b)(1)(A)(ii), evaluate and designate 
        additional priority transboundary aquifers.
    (d) Cooperation With Mexico.--To ensure a comprehensive assessment 
of transboundary aquifers, the Secretary shall, to the maximum extent
