Obtaining a Well Permit
The Environmental Health Division participates in the COUNTY WELL DELEGATION
PROGRAM of the Wisconsin Department of Natural Resources.
The program allows the division to review all well locations before the well
is installed. Prior to the issuance of a well location permit, the following
requirements are reviewed: the proposed well elevation, site location, set back
distances to contamination sources, buildings, and property lines. A follow-up
inspection is made after the well is installed. This includes verifying the
actual location, height, and set backs of the new well and checking the well cap
and the pumps wiring for proper seals.
This division also orders the proper abandonment of unused wells.
To obtain a current list of state licensed well drillers and pump installers who
perform work in La Crosse County, please call (608) 785-9771.
