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. Table 1. -- Field Descriptions UNIQID Unique identifier. TRACKNO Tracking number assigned by the Information Systems Programs to each HSSR record to identify the source file from which the record was taken. TAPEDAT Date on which the data release tape was created.

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. BOTAN 0 = not part of special botanical study, 1 = part of special botanical study. REPLDUP Identifies the sample as one of a set of replicates: 0 = not part of special study, 1 = part of special study. SITEDUP Identifies the samples as one of a set of samples collected at exactly the same site: 0 = not part of special study, 1 = part of special study. REPL Replicate code used to distinguish between samples of the same type collected from the same site. XSITE Cross reference site number used as a quality control number.
