Maps


GeoSTRAT

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

Owners of private water wells should take precautions if the threat of flooding exists, and specific steps should be taken if water wells are impacted by flood waters. It is important to disinfect a water well if the well has been impacted by flood water, a water sample tests positive for bacteria, or when work on the well, such as a pump replacement or liner installation has been completed. The following links provide helpful guidance.

When Repairs are Needed

If repairs need to be made to the water well, hire a contractor to do the work. Contractors licensed to do business in Missouri may be found online by using mowells.

Bacteriological Testing

For more information about bacteriological testing for private drinking water please contact the following agencies:


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 swcd.mo.gov.
