Data Quality
Resource level dataset
Data quality report - Completeness omission  Measure description 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.
Data quality report - Quantitative attribute accuracy  Measure description The mapping was conducted after a thorough documentation of well locations and water well record details.
Data quality report - Absolute external positional accuracy  Measure description 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.
Lineage  
Process step  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, groundwater availability, bedrock topography, and surface topography.
Process step  When the process occurred 2012-03-14T00:00:00
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.
Process step  
Description A polyline coverage was created using the heads-up-method and attributed by Glenn E. Grove. Attribute definitions are described below.
Source data  Description Water well records from the IDNR-DOW well record database; USGS topography maps; various consultant geotechnical reports
