[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 419 sediment and 437 water samples were collected from streams and lakes within the Petersburg quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Petersburg Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected by contracted personnel during September of 1979. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements. LASL was unable to complete the Petersburg quadrangle data release report. The data was sent to and released by the Bendix Field Engineering Corporation in Grand Junction, Colorado only as a microfiche GJBX-163(82) report. This report does not give any details on the sample collection or analytical methods used on these samples.
The 437 water samples were sent to the Oak Ridge Gaseous Diffusion Plant (ORGDP) to be analyzed for uranium and 29 additional elements. The analytical data were released in the GJBX-278(81) report.
The following is a list of NURE sample types collected in the Petersburg quadrangle.
| Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
|---|---|---|---|
| Wet Streams | 266 | Streams | 268 |
| Wet Lakes | 153 | Lakes | 169 |
| Total Sediments | 419 | Total Waters | 437 |
These Petersburg quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
The data in the NEW-FORMAT NURE data files consist of reformatted sediment records from the GJBX-163(82) report and reformatted water record from the GJBX-278(81) report.
The data files are in dBase IV .dbf format. A complete description of the data fields and coding schemes is available online - On-Line Manual for New-Format NURE HSSR Data Files. The data are transferred as gzip .gz compressed files. Simply activate the links below to download the data files. Use gunzip or popular commercial and shareware decompression programs to expand the .gz files. Additional information and executable versions of gzip and gunzip for various systems are available on the gzip home page.

Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.
LASL compiled all of the regional HSSR data from Alaskan NURE studies and produced a report [GJBX-32(83] that graphically displays the distribution of selected elements for most of the State. No additional geochemical data were released with this report.
