LineageHua Zhang, the project hydrogeologist, selected several wells from the County Well Index (CWI), and some surface water points, and had them sampled by the geology lab at the University of Minnesota for chemical analysis. Wells were chosen based on reliability of geologic information, regional distribution, and well accessibility.

The results were recorded in an Excel file, which was made into an ARCINFO coverage by the following method:

1) Two comma separated value files were made, one with just the unique number, x, and y coordinates, and one with all other fields plus the unique number.

2) The comma separated value file with the unique number, x and y coordinates was converted into a point coverage in ARCINFO using the arc command, 'generate.'

3) The other comma separated value file was converted into an INFO file.

4) The ARC command 'joinitem' added the INFO file to the point attribute table of the coverage using the unique number as the relate item.

Note on sub-section descriptions:

Upper case letters after the section number indicate the location within the section; the first letter denotes the 160 acre (quater-section) tract; the second, the 40 acre tract; the third, the 10 acre tract, continuing by quarterly divisions of each tract to a progressively finer resolution. 

The letters A,B,C,D are assigned in a counterclockwise direction, beginning in the northeast corner of each tract.

The number of upper case letters indicates the accuracy of the location description
