Brief History and Description of Data
[See History of NURE HSSR Program for a summary of the entire program.]
LASL: Havre Quadrangle
Totals of 1,200 sediment and 652 water samples were collected from the Havre quadrangle during July - August 1978 as part of the Los Alamos Scientific Laboratory (LASL) Havre Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. The samples were analyzed by LASL for uranium and up to 43 additional elements. The analytical data were released on microfiche by Bendix Field Engineering Corporation as the Havre Quadrangle NURE HSSR study GJBX-184(81) report.

These Havre quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
- LA1: Los Alamos Delayed-Neutron Counting Analysis of sediments for U.
- LA3: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of sediments for Ag, As, Bi, Cd, Cu, Nb, Ni, Pb, Se, Sn, W, and Zr.
- LA5: Los Alamos Neutron Activation Analysis of sediments for Al, Au, Ba, Ca, Ce, Cl, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th, Ti, V, Yb, and Zn.
Water Samples
- LA6-FL: Los Alamos Fluorometry Analysis of waters for U.
Discussion of the Reformatting Process for Havre Quadrangle
The Havre quadrangle sediment and water data of reformatted records from the Havre Quadrangle NURE HSSR study GJBX-184(81) report. The following problems were found and addressed during the comparison and reformatting stages for the Havre quadrangle data:
Sediment Records
- During the NURE sample collection phase, LASL sites and samples were initially assigned a 6-digit integer Identification Number (LASLID) starting with 000001. After 1977, most LASL sites were reassigned a new 1-letter+5-digit Identification Number starting with A00001. All LASL samples and the early LASL reports use the 6-digit integer LASLID. Most of the later reports only use the 1-letter+5-digit LASLID. Although both sets of numbers were usually assigned sequentially, they do not correspond one to one with each other: 100001 does not equal C00001, etc. Whenever possible, the 1-letter+5-digit LASL Identification Number was saved in the LASLID field. When the corresponding 6-digit site number could be determined from sample number translation key lists or other sources, this Identification Number was saved in the SITE field.
- No LASL Identification Number translation key was found for the Havre quadrangle sediment samples. The 6-digit LASL Identification Number found in LASLID was also added to the SITE field. Therefore, the value found in the LASLID and SITE fields is same LASL Identification Number used to label the original field maps, field notes, and sample containers as well as the value published in Havre Quadrangle NURE HSSR study GJBX-184(81) report.
- Unlikely sample collection dates were found for five samples. These dates were removed from the SAMPDAT field. For each record, the original SAMPDAT value and the most likely correct value was added as a comment to the REFORMAT field.
Water Records
- No LASL Identification Number translation key was found for the Havre quadrangle water samples. The 6-digit LASL Identification Number found in LASLID was also added to the SITE field. Therefore, the value found in the LASLID and SITE fields is same LASL Identification Number used to label the original field maps, field notes, and sample containers as well as the value published in Havre Quadrangle NURE HSSR study GJBX-184(81) report.
- An unlikely sample collection date was found for one sample. This date was removed from the SAMPDAT field and the original SAMPDAT value with the most likely correct value was added as a comment to the REFORMAT field.
Download The Data
The NURE HSSR data are now available online in two databases: The sediment database (also includes data for soils and some rocks) at http://tin.er.usgs.gov/nure/sediment/ and the water database at http://tin.er.usgs.gov/nure/water/. From these two web sites, NURE HSSR data can be selected, examined, summarized, and downloaded by political boundaries (State and County), by quadrangle (1:250,000-scale, 1:100,000-scale, and 1:63,360-scale for Alaska or 1:24,000-scale for the Lower 48 States), and by hydrologic unit (drainage region, subregion, river basin, or sub-basin). Selected data can be downloaded as a dBase file, a shapefile, an HTML table, or ASCII text (tab- or comma-delimited).

Havre Quadrangle NURE Summary
A summary report for the Havre quadrangle was released by the Bendix Field Engineering Corporation of Grand Junction, Colorado [PGJ/F-119(82)]. An additional 25 stream water, 43 well water, 31 sediment, and 112 rock samples were collected from all areas of the quadrangle except for unaccessible portions of the Bearpaw Mountains. The samples were analyzed and the multielement analytical data for the samples were released only as appendices on microfiche accompanying the summary report.
