Continuing obligations apply to one or more properties due to remaining contamination. For information specific to the continuing obligations, review the documentation below. Before constructing or reconstructing a water supply well, you need to contact DNR for approval of well construction specifications.

Waste Sites are sites that are located on the same property as a landfill licensed under Wis. Admin. Code NR500 or on a known historic waste site never issued a license by the DNR. Prior to constructing or reconstructing a water supply well, you need to contact DNR for approval of well construction specifications. You may also need approval to build or excavate. Please see the documentation below or contact the DNR Project Manager or DNR File Contact listed at the bottom of this page.
