   A Brief History of the Geochemical Sampling Program

       This report represents work performed by the Bendix Field
       Engineering Corporation, Operating Contractor for the U.S.
       Department of Energy (DOE), as part of the National Uranium
       Resource Evaluation (NURE) program, and by the U.S. Geological
       Survey (USGS).  Beginning in 1974, NURE program personnel
       acquired and compiled geologic and other information required to
       evaluate the extent and distribution of uranium resources and to
       determine areas favorable for the occurrence of uranium in the
       United States. The Hydrogeochemical and Stream Sediment
       Reconnaissance (HSSR) survey was part of the NURE program.
  
       Sampling for the HSSR survey began in 1976 and ended in 1980.
       Most of the sample types collected were stream sediment, soil, and 
       surface- and ground-water samples.  Four DOE national
       laboratories contributed to the survey: Lawrence Livermore
       Laboratory, Los Alamos Scientific Laboratory, Oak Ridge Gaseous
       Diffusion Plant, and Savannah River Laboratory.  Each DOE laboratory 
       pursued its own system of sample collection, analysis, and data
       management.  In 1977, the laboratories were instructed that all 
       sampling and data management were to conform to the 1 degree by 
       2 degree grid system.  This decision resulted in incomplete coverage 
       in some States, mainly along State borders.  Some areas were
       sampled by more than one of the four laboratories.  Originally, the 
       samples were analyzed primarily for uranium.  In 1977, analyses for 
       additional elements were added.  These procedures were sometimes 
       altered during the life of the program.

       The procedural changes resulted in 47 different data formats.  Under
       contract with the Information Systems Programs of the Energy
       Resources Institute, University of Oklahoma, the DOE initiated
       the reformatting of a substantial portion of the data into one
       format.  In 1983, a memorandum of understanding between the DOE
       and the Department of the Interior was signed transferring
       responsibilities for maintenance of HSSR samples and HSSR data
       collected under the NURE program to the U.S. Geological Survey.

   Data on this CD-ROM

       The data published on this CD-ROM are from the conterminous
       United States.  The data represent sampling from 320 National 
       Topographic Map Series (NTMS) 1 degree by 2 degree quadrangles. 
       The number of records on the CD-ROM is 678,558.  All elemental
       concentrations, as well as sulfate concentrations, are reported 
       in parts per billion (ppb).  A negative sign indicates that the
       concentration is less than the indicated lower limit of detection.
       The sample type codes are explained in the following section.
       For most records, the sample media are coded in the SAMPTYP field.
       For those records not coded in this manner, the use of other 
       fields is required to determine the sample media.  For those records, 
       the alternate sample media coding field is also listed in the table 
       below.

       NOTE:  The sampling originally included the Montreal quad, which
              has been discontinued.  The 32 records which were originally 
              in the Montreal quad have been incorporated into the Lake 
              Champlain quad.

       REPTYP    Indicates that the sample was collected as part of a   
                 special study rather than as part of the
                 reconnaissance-level study: 
                   P = pilot study, 
                   D = detailed study, 
                   S = special study.
