What the source says
Is the water from the well required to be tested at the time of property transfer? The state of Minnesota does not require testing private well water at the time of property transfer. However, many lending institutions may require testing, typically for coliform bacteria and nitrate, as a condition for approving a loan for the purchase of the property. In Dakota County, however, a local ordinance requires wells to be tested at the time of property transfer.
