NOTE: An updated data set named WATERWELLS_DNR_WATER_IN_120312.SHP was provided to Indiana Geological Survey personnel on March 15, 2012, by Mr. Michael P. Martin, GIS Coordinator, Indiana Department of Natural Resources, Division of Outdoor Recreation.
NOTE: An updated data set named WATERWELLS_DNR_WATER_IN_130530.SHP was provided to Indiana Geological Survey personnel on July 23, 2013, by Mr. Michael P. Martin, GIS Coordinator, Indiana Department of Natural Resources, Division of Outdoor Recreation.
The following is excerpted from the metadata provided by IDNR for the source shapefile WATERWELLS_DNR_WATER_IN_130530.SHP:
"This file is a digital geospatial point feature class of both located water well records (which include UTM coordinates) and unlocated water well records (without UTM coordinates as of 200911). The estimated locations used for the unlocated wells were based on the polygon centroid values for the smallest indicated section, quarter, quarter-quarter, or quarter-quarter-quarter section (as indicated in the database) for over 250,000 water well records and for about 26,000 of the 250,000 water well records the UTM's were obtained from address geocoding using the owners address, a generally more accurate method (see process steps below)."
"The Division of Water Ground Water Database has approximately 400,000 water well records, and of those, approximately 145,000 have been field located and have x, y (UTM) coordinates. The remaining records have no utms and cannot be easily utilized in a GIS format. The purpose of this shapefile was to include those wells with UTM coordinates and to approximate the UTM coordinates for the others based on the most precise Township, Range, Section, quarter sections (TRS) locations available from office locating, which is effectively the centroid of the smallest known section or quarter sections; thus, increasing the amount of data available for display and analysis in a GIS format. This shapefile is combination of the located water well records and the water well records for which an estimated location was able to be determined using the methods described below. This leaves less than 15,000 records with no UTM's associated with them. This shapefile and associated table has selected fields from the main digital water well database that are typically needed for most research."

"Records that did not have locations provided and whose locations could not be estimated using the public land survey system descriptions were removed from this version of the database."
"Checks for duplicates (unique values in unique records) were performed on this data set. No checks on topology were performed on this data set."
"Locations based only on the street address, driving directions, or other location information provided on the well record are considered unlocated records and have no x, y coordinates, only township, range, section, and quarter-quarter-quarter sections (if estimated).
"The x, y coordinates are from the calculated centroid of the smallest possible individual polygon that matched the water well location data. Some records have no quarter sections and/or some of the polygons could not be subdivided, so the centroid of the section was used for those water well records. These are the least accurate coordinates and in a regular one-mile square section the x, y coordinates will generally be within a half-mile of the office located section, on irregular sections, the distance may be greater. The best location values are on the records with quarter-quarter-quarter sections and typically will be within 150 meters of the office located quarters.
"A small number of the data points were checked for accuracy and methods used should keep the x, y coordinates within the proper section in most cases. However, due to the complexity and in cases redundancy in the public land survey system for Indiana some x, y pairs may not be located in the proper section or even the proper county. Other sources of error may be caused by misinterpretation of the driving directions or office locating. Several areas have different survey systems than the Congressional TRS (Clark Military Grant, Military Donations, Meridian Road Lines, Indian Treaties etc.) and no attempt at this time was made to provide centroids for these areas.
"Located records were primarily field located based on the location identified on the USGS 1:24,000 7.5 minute series topo map by the field locator. In some cases the structure or subdivsion may not be on the map and location is based on topography. So some error may be inherent in the field locations and points placed on the map ( a single point on a map may be 100 feet across). The scale is based USGS 1:24,000 7.5 minute series topographic maps. However, in most cases locations of mislocated wells can have large errors, with the reported locations having no meaning."
