Well Construction Information

Testing your drinking water is important, but only gives you information about your water quality at one moment in time.  To have safe water over the long term, your well must be properly located, constructed, and maintained.

Well construction reports for wells installed by licensed contractors since 1936 are kept at the Wisconsin Geological and Natural History Survey in Madison.  A well construction report can tell you such details as:

• well depth
• amount of casing in the well
• depth to water in the well
• amount of drawdown in the well when it is pumped
• types of soil and rock that were drilled through, and type of material in which the well is completed

To obtain a copy of the Wisconsin Well Construction report for your well, you can contact the Wisconsin Geological and Natural History Survey.
