  Description:
    Abstract: This data set was created for SIR2008-5015 to map hydrochemical regions of the glacial aquifer system.  It includes the area of the glacial aquifer system boundary (glacbnd) in the United States and all of the NAWQA wells identified as being in the glacial aquifer system study.  The area is approximately 11 kilometers larger in most of the area of the glacial aquifer system; however, areas in Washington state and in Kansas and Nebraska were enlarged manually to include an adequate area around the wells in the glacial aquifer system study.
    Purpose: This data set was created for SIR2008-5015 to map hydrochemical regions of the glacial aquifer system.

      Process_Description:
                Clipped glacial boudnary spatial data (glacbnd) to the area of the United States.  Buffered area around the clipped boundary by 11 kilometers. Hand edited the area of the buffer in Washington state and Kansas/Nebraska to include the wells in those areas that were identified as being in glacial material but outside of the glacial boundary (glacbnd) area. See published report for a description of why these wells were included.
