                                 A BILL


 
  To direct the Secretary of the Interior to conduct a study of water 
 resources in the Rialto-Colton Basin in the State of California, and 
                          for other purposes.

    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 ``Inland Empire Perchlorate Ground 
Water Plume Assessment Act of 2009''.

SEC. 2. RIALTO-COLTON BASIN, CALIFORNIA, WATER RESOURCES STUDY.

    (a) In General.--Not later than 2 years after funds are made 
available to carry out this Act, the Secretary of the Interior, acting 
through the Director of the United States Geological Survey, shall 
complete a study of water resources in the Rialto-Colton Basin in the 
State of California (in this section referred to as the ``Basin''), 
including--
            (1) a survey of ground water resources in the Basin, 
        including an analysis of--
                    (A) the delineation, either horizontally or 
                vertically, of the aquifers in the Basin, including the 
                quantity of water in the aquifers;
                    (B) the availability of ground water resources for 
                human use;
                    (C) the salinity of ground water resources;
                    (D) the identification of a recent surge in 
                perchlorate concentrations in ground water, whether 
                significant sources are being flushed through the 
                vadose zone, or if perchlorate is being remobilized;
                    (E) the identification of impacts and extents of 
                all source areas that contribute to the regional plume 
                to be fully characterized;
                    (F) the potential of the ground water resources to 
                recharge;
                    (G) the interaction between ground water and 
                surface water;
                    (H) the susceptibility of the aquifers to 
                contamination, including identifying the extent of 
                commingling of plume emanating within surrounding areas 
                in San Bernardino County, California; and
                    (I) any other relevant criteria; and
            (2) a characterization of surface and bedrock geology of 
        the Basin, including the effect of the geology on ground water 
        yield and quality.
    (b) Coordination.--The Secretary shall carry out the study in 
coordination with the State of California and any other entities that 
the Secretary determines to be appropriate, including other Federal 
agencies and institutions of higher education.
    (c) Report.--Upon completion of the study, the Secretary shall 
submit to the Committee on Energy and Natural Resources of the Senate 
and the Committee on Natural Resources of the House of Representatives 
a report that describes the results of the study.
