Domestic wells represent potential conduits or direct pathways for surface contaminants to reach the groundwater supply. For example, holes in the basement floor can easily be mistaken as drains to the sewer system. The proper abandonment of an unused well by closing and sealing the connection between the land surface and the groundwater avoids the possibility of contamination.Under current Wisconsin law, only licensed well drillers and pump installers can fill and seal wells. These licensed professionals must follow the regulations codified in Wisconsin Administrative Code, Chapter NR 812.
A list of licensed well drillers and pump installers is available on the Department of Natural Resources website.
Well abandonment MUST include completion and submittal of a DNR Well Abandonment Form. If you are unable to obtain online access, paper forms are available in the La Crosse Utilities Office. This form must be completed by the licensed well driller or pump installer; the contractor must also submit a copy to the DNR within 10 days of the abandonment. Well owners are advised to make sure all of the abandonment paperwork has been competed, submitted and copy given to them for their records BEFORE making final payment to the contractor performing the well abandonment.
A copy of the completed abandonment paperwork should also be submitted to:
