Well Installation Online Services

The Well Installation Online Services application enables you to:

  • Test for a permit.
  • Renew a permit.
  • Submit a record.
  • Search for well or pump installation contractors licensed to do business in Missouri.
  • Search well records for wells drilled, reconstructed, or plugged after July 1987.

Also available online is the prenotification form for permit holders.


Find locations of wells and related information using the department’s online Geosciences Technical Resource Assessment Tool, known as GeoSTRAT. GeoSTRAT enables users to easily visualize and explore geospatial data using an interactive map. This interactive tool recently received a significant upgrade. It now makes geologic and geotechnical data readily available on mobile devices, as well as on personal computers and no plug-in is needed.

Flooded Wells

The following external links provide precautions and steps to take if your well is impacted by flood waters. For more information on bacteriological testing for private drinking water please contact the Missouri Department of Health and Senior Services or your County Health Department.

Abandoned wells present a hazard

An open well is considered abandoned when it can no longer be used or when it has not been in use for two years or more. Cisterns and wells with wide openings pose a serious physical hazard, especially to children and animals. Contaminants can enter our groundwater through all types of abandoned wells, including drilled wells. Learn more about plugging abandoned wells.

Report abandoned wells online

A feature is available using the online “Report an Environmental Concern” form that allows reporting of abandoned wells. To aid in location of the well, please provide GPS latitude and longitude coordinates when possible. You may add your email address if you would like to be contacted; otherwise, reporting is anonymous.

Cost-share funding available

The department's Soil and Water Conservation Program has funds available for plugging water wells. The primary funding for these cost-share practices comes from the one-tenth-of-one-percent Parks, Soils and Water sales tax. Details about the cost-share program are available at local district offices. Locate district offices at
