This layer contains the boundaries of the public water supply districts (PWSD) in the State of Missouri
This layer was originally developed for use in the MoDNR-funded Vulnerability Assessment (VA) of Missouri Public Drinking Water to Chemical Contamination Project at CARES. The VA project was implemented in 1991 by MoDNR. MoDNR - PDWB 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.

Water district service areas (boundaries) are typically static. However, from time to time the service areas may change. These changes are not always reflected in the current Geograpic Information Sysytem (GIS) data set. Changes are only made if the water district notifies the PDWB of the change and supplies a description of the new service area. Districts that have been broken into mutiple contiguous areas for sampling have been merged into a single polygon
Water districts that have not submitted their service area are not included. This data set contains only active water districts.
Location accuracy varies based on the method used to locate the feature. The original layer was digitized by CARES from 1:100,000-scale United States Geologic Survey (USGS) topographic maps. PWSD's were asked to furnish legal descriptions. These were used to replace the 1:100,000-scale boundaries with 1:24,000-scale boundaries digitized from USGS 7.5' quadrangle maps. When available Computer-aided Design (CAD) files furnished by the water supply were used to further define the district boundary.
This dataset contains no elevation data.

1. The original layer was digitized from 1:100,000-scale USGS topographic maps. 2. PWSD's were asked to furnish legal descriptions. These were used to replace the 1:100,000-scale boundaries with 1:24,000-scale boundaries digitized from USGS 7.5' quadrangle maps. 3. Additional information from the PWSD or PDWB is incorporated as it becomes available. 4. CARES staff reprojected the original North American Datum (NAD) NAD27 coverage to NAD83 using ArcInfo 8. 5. For MoDNR use, CARES reprojects the coverage to NAD27 and exports the coverage and compresses the resulting .e00 file. 6. .e00 files were converted to Arcview 3.2 shapefiles by Geological Survey and Resources Assessment Division (GSRAD) 7. Water districts, which had multiple records and polygons, were unioned to give a single record with multiple polygons. The exception for this was if the two polygons were of approximately equal size and were significantly separated.
