National Geochemical Database—Reformatted Data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) Program

Version 1.40 (2006)

Brief History and Description of Data

[See History of NURE HSSR Program for a summary of the entire program.]

Totals of 1,352 sediment and 1,387 water samples were collected from 1,455 locations during July of 1977 within the Healy quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Healy Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. All samples were analyzed by LASL for uranium. The sediment samples were additionally analyzed for up to 43 more elements. LASL was unable to complete the Healy quadrangle data release report. The data were sent to the Bendix Field Engineering Corporation in Grand Junction, Colorado and subsequently published as the microfiche GJBX-88(81) report. This report does not give any details on the sample collection or analytical methods used for these samples. (Note: The original Healy digital data files included one sediment sample and one water sample that were actually collected at a single lake site just outside of the Healy quadrangle within the Mt. McKinley quadrangle. The numbers of samples discussed herein reflect the removal of those samples.)

The following is a list of NURE sample types collected in the Healy quadrangle.

*Summary of Healy quadrangle sample types.*
Sediment Sample Type	Number of Samples	Water Sample Type	Number of Samples
Wet Streams	772	Streams	797
Dry Streams	58	Lakes	587
Wet Lakes	517	Artificial Ponds	3
Dry Lakes	1
Wet Artificial Ponds	3
Dry Artificial Ponds	1
Total Sediments	1,352	Total Waters	1,387

These Healy 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.
LA2: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of sediments for Ag, Bi, Cd, Cu, Nb, Ni, Pb, Sn, and W.
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.
LA4: Los Alamos Arc-Source Emission Spectrography Analysis of sediments for Be and Li.
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.

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of reformatted records from the GJBX-88(81) report. Any changes in the data or problems found are noted in the REFORMAT comment field. The aforementioned lake sediment and lake water samples collected at a single lake site outside of the Healy quadrangle were removed from the Healy quadrangle data files and added to the Mt. McKinley quadrangle data files.

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 websites, 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).

Healy Quadrangle Sediment Data - 1,349 records
Healy Quadrangle Water Data - 1,384 records

Notes for Data Users

Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.

Other NURE Geochemical Data for the Healy Quadrangle

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.
