Data Quality
ATTRIBUTE ACCURACY 
ATTRIBUTE ACCURACY REPORT 
The mapping was conducted after a thorough documentation of well locations and water well record details.
COMPLETENESS REPORT 
In conducting the mapping, the author(s) evaluated hundreds of water well records, especially those having relatively complete information on well location, static water level, well depth, ground elevation, and lithology. There were areas in the county with sparse information because of lack of well records or incomplete records.
POSITIONAL ACCURACY 
HORIZONTAL POSITIONAL ACCURACY 
HORIZONTAL POSITIONAL ACCURACY REPORT 
The locations of many wells were field checked and the locations posted on 7.5 minute topographic maps. Visual confirmation of wells was not always possible. Many locations were based only on the street address, driving directions, or other location information provided on the well record.

PROCESS STEP 
PROCESS DESCRIPTION 
The hand-drawn work maps (scale 1:24,000) showing lines of equal potentiometric surface elevation were digitized and edge matched in ESRI ArcEdit (ArcScan) by Scott H. Dean. The maps were individually georeferenced using a minimum of 4 tics per map. Projection was UTM, Zone 16, NAD83.
PROCESS DATE 2011-01-01 
PROCESS TIME 000000
PROCESS STEP 
PROCESS DESCRIPTION 
Data were selected by careful evaluation of water well records to determine if the wells were field located and if they contained complete and reasonable information.
SOURCE USED CITATION ABBREVIATION 
IDNR-DOW records for domestic and other supply wells submitted by water well drillers from 1959-2011 
PROCESS DATE 2011-01-01 
PROCESS TIME 000000
PROCESS STEP 
PROCESS DESCRIPTION 
After selection of water well records was complete, specific well data and other maps and reports were considered in the mapping process. For example, ground elevation, static water level, well depth, aquifer top and bottom elevation and lithology were obtained from well records. Other maps and reports included regional potentiometric surface elevations, hydrogeologic settings, ground-water availability, bedrock topography, and surface topography.
