Shared Wells: Testing Requirements

OREF 082 – Private Well Addendum should be used even if the property is serviced by a shared well. The Oregon Health Authority requires that in the sale of property that includes a well that supplies ground water for domestic purposes, the seller shall have the well water tested for arsenic, nitrate, and total coliform bacteria. If the property includes an interest in a well on adjacent property, including an easement, that interest would be considered part of the real property. The tests would be required, even for a shared well not located on the property.

All comments and responses from OREF or its staff, managers, and volunteers are non-legal opinions made for general purposes. Each Forms subscriber must rely solely upon their Principal broker or personal legal counsel for specific advice and instruction. You and your client should independently confirm that the Form(s) you use are legally suitable for the purposes intended and that they are current with respect to all laws and regulations.
