Well Information from County Well Index for the General Public

The County Well Index (CWI) geodatabase was developed by the Minnesota Geological Survey (MGS) and is maintained in cooperation with the Minnesota Department of Health (MDH). CWI contains basic information for over 511,000 water-wells, and borings drilled in Minnesota. The data is derived from water-well contractors' logs of geologic materials encountered during drilling. Confirmed locations and geologic well records are available for over 325,000 of the wells. Available data also includes casing, screen and pump information. This dataset does not include public water supply wells. <br/><br/>This data resource is a regularly updated copy of the database and is maintained by MNIT Services.

dsPurpose This dataset was developed with the intention of protecting the drinking water supply. MGS and MDH's Well Management Program protect both public health and groundwater by assuring the proper construction of new wells and borings, and the proper sealing of unused wells and borings.

Public water supply well locations are restricted information and are therefore not included in this dataset.
