Read Me File For Plate III and Associated GIS Layers*:
NURE Aeroradiometric Anomalies
(This read me file written by: Jonathan Kim, Vermont Geological Survey, August 2002)

Required Files
Vt nure preferred anomalies.dbf, Vt nure preferred anomalies.shp, Vt nure preferred anomalies.shx

Vt nure secondary anomalies.dbf, Vt nure secondary anomalies.shp, Vt nure secondary anomalies.shx

        These are GIS coverages of anomaly areas delineated by Texas Instruments airborne radiometric survey in Vermont completed for the U.S. Dept. of Energy, National Uranium Resource Evaluation (NURE) in 1976. Preferred anomalies were thought to be more favorable for the presence of uranium than secondary anomalies. This data was scanned from 1:250,000 scale maps in the Vermont Geological Survey archives. The data was scanned into a tiff file using a Titan Scanner and Truinfo software, georectified in ERDAS Imagine, and digitized in Arcview 3.2a.

Geodetic Information NAD 83 Vermont Stateplane coordinates (Zone 5526) in meters

This coverage was digitized from original 1:250,000 scale maps and data and, therefore, use at this scale is recommended. Accuracy may diminish when enlarged beyond this scale.

The only way to determine with certainty if groundwater from a particular well has elevated radionuclide levels is to have the water tested by a certified lab. The Vermont Department of Health recommends that all private well owners test their wells for naturally-occurring alpha radiation every 5 years http://healthvermont.gov/enviro/ph_lab/water_test.aspx#two. This map should not be used as a replacement for detailed, site-specific studies by competent technical personnel.

This map (and the other eight maps in this series) displays geological and geophysical data compiled from surveys conducted at various times over several decades. The information used in preparing the map(s) represents the best data possessed by the Vermont Agency of Natural Resources at the time of production. The data is subject to revision at any time and the map user should contact the Vermont Agency of Natural Resources to determine whether there have been any changes in the data on which the map was based.

Although every effort has been made to faithfully portray the information from the surveys, the Agency of Natural Resources cannot vouch for the accuracy of the data on which the map(s) was based. No warranty as to the accuracy or the usefulness of the data on the map(s) is expressed or implied.
