Description:
Abstract:
The Well Management database was queried and data extracted on December 31, 2012. Data was processed from 10 tables and reconstructed to create a file geodatabase with only the actual well sealing records. Geocoding was accomplished in a phased approach. 1. Match to a County Well Index located well. 2. Match to an inventoried PCSI location 3. Match to a physical address with zipcode using a composite address locator. 4. Match to Public Land Survey System (PLSS) coordinates. Townhip, Range, Section and subsection. Finally a shapefile was generated for general distribution. About 2,000 records did not have any location information and are not included in the data distribution.
Purpose:
The Well Management Program maintains records on sealed wells. The Source Water Protection Program protects public water supply wells through wellhead protection. A potential contaminant source inventory (PCSI) is required for all wellhead protection areas. A well inventory is required as part of the PCSI.

Use_Constraints:
Only a few sealed well locations have been verified, many locations may be inaccurate. The Accuracy field will give an indication of the estimated accuracy of the sealed well location. Only an accuracy of 25 is considered located. This means that the location should be within 25 meters of its actual location. Accuracy values are derived from estimates based on the geocoding method employed for the sealed well locations.
