[ Update this Record ]

Summary

Abstract: This is a point coverage of the sampling sites for the U.S. Geological Survey
National Water-Quality Assessment (NAWQA) Program Study-Unit investigations of
Surface Water Nutrients for the conterminous United States, excluding the High
Plains Regional Ground-Water Study. It is intended for use with NAWQA_NU.DBF
and as an overlay with NAWQA, the NAWQA study units boundary coverage.

Quality This data set is used primarily to display the location of NAWQA
Nutrient Study Sites and for use with the NAWQA Study Unit boundaries
coverage (NAWQA) for analysis of data at the national scale. It is not
recommended for either local or regional analysis due to the small
scale of most of the features.

The dataset was created from Latitude/Longitude coordinates using
ArcView GIS. A shapefile was created from lat/long coordinates and was
then converted into a coverage using ArcInfo. The coverage was
re-projected into Albers for use with other CAMD GIS coverages.
