This layer was originally developed for use in the MoDNR-funded Vulnerability Assessment (VA) of Missouri Public Drinking Water to Chemical Contamination Project at Center for Applied Research and Engagement Systems (CARES). The VA project was implemented in 1991 by MoDNR. MoDNR contracted with CARES to conduct this assessment. The project is designed to determine which, if any, public water supplies are threatened by any chemicals being tested under the Safe Drinking Water Act.

Where field verification of data is performed, the methodology used varies. The methods used for verifying locations are listed under the attribute named METHOD. See positional accuracy report for more information.
Tests for integrity have not been performed.
This data set contains known public water wells in the State of Missouri.
Locational accuracy varies based on the method used to locate the feature. Locations derived from United States Geological Survey (USGS) digital raster graphics (DRG) 7.5 minute topographic quadrangle maps are accurate to no more than 40 feet. Locations derived from USGS Digital Orthophoto Quarter-Quadrangles (DOQQ) are accurate to no more than 33 feet. Data collected using global positioning system (GPS) receivers are accurate to somewhere between 10 and 100 feet. Locations derived using the Public Land Survey System (PLSS) are accurate to no more than 165 feet. The accuracy of locations derived from other map sources varies. Specific accuracy for each record is given under the attribute named "ACCURACY".
Elevation values reported to sub-foot accuracy were surveyed with precise instruments. Accuracy of that data is dependent on the accuracy of benchmarks used for the survey. All other elevation values are determined by locating wells on USGS 7.5 minute topographic quadrangle maps and interpolating elevation values from the contours shown on the maps. Vertical accuracy is impacted by the accuracy of the data source, the methods used to locate each well on a topographic map, and the horizontal and vertical accuracy limitations of the topographic map used to determine elevation values.

1. Public water system permits are issued and approved. Data is entered into the
MoDNR PDWB database.
2. MoDNR PDWB regional office personnel locate wells using USGS topographic or other maps, PLSS, global positioning system (GPS) receivers, and digital
orthophotography.
3. These points are digitized and populated with attribute data. Additional data sent in by public water suppliers is incorporated as it becomes available.
