Sellers must disclose wells on property
According to Dakota County Ordinance 114 – Wells and Water Supply Management, the property owner must disclose the location, condition, water quality and the measures to be taken to bring all new and existing wells into conformance with this ordinance prior to a property transaction. Water analysis must be performed by a Minnesota Department of Health certified laboratory using approved methods within six months prior to a property sale.

It is the duty of the property owner to complete a Well Disclosure Certificate for all wells on the property and file the certificate with the County Recorder as required by Minnesota Statute 103I. 235 and any subsequent amendments.
Water testing requirements
All existing potable well water supplies that are part of a property transaction must be tested according to the following requirements:
- Private wells must be tested by a Minnesota Department of Health certified laboratory, using approved methods within six months prior to a property transaction. Samples for the property transaction must be collected by an independent third party using appropriate sample collection procedures.
- Private wells that are the primary water supply and are part of a property transaction must meet applicable drinking water standards as defined in Ordinance 114.

At the time of a property transaction, all unused wells must be permanently sealed as required in Section 1100 of Ordinance 114. If the well is not permanently sealed, the well must be permitted as required in Section 1200 of Ordinance 114 or be brought back into working condition and used if the use of the well does not pose a threat to the quality or quantity of groundwater.
