The Minnesota Department Of Health (MDH) statute 4725 states not-in-use wells must be made operable, sealed, or granted a variance, before a property is sold. MN statutes 103I.301 states the “property owner” is responsible for sealing any unused well(s).
Not-in-use wells must be sealed by an MDH approved, licensed contractor. The contractor must document and file the well sealing record with MDH.
Even though a well may have been properly sealed, if there is no proof or document
on file with MDH, they require removal of the existing sealing material from the well;
then resealing and documenting it with them. A possible alternate is to get a variance
from MDH, which has an annual fee. In 2015 the fee was $75.00/year.
What is the cost to abandon (also known as sealing or capping) a well?
Prices vary, primarily based on well depth, well diameter and ease of access. A larger diameter well and/or deeper well will require more time and sealing material. A well that can be accessed with a hoist truck (so the hoist can be used to remove the equipment from the well) is less expensive than a well that requires manual (hand pulling) removal of the equipment from the well.
