Important Notes for MWI Users

The Minnesota Well Index (MWI) provides information about wells and borings in Minnesota. The MWI provides basic information, such as location, depth, geology, construction and static water level, for many wells and borings drilled in Minnesota. It by no means contains information for all the wells and borings and the absence of information about a well on a property does not mean there is no well on that property.To successfully use MWI, please note the following:

  • Due to security concerns, wells supplying public water systems are not displayed in MWI. If you need access to this information, please contact:
    Brian Johnson at 651-201-4688 or brian.johnson@state.mn.us; or
    Jim Walsh at 651-201-4654 or james.f.walsh@state.mn.us.
