I would guess that the deed probably has ownership to MHHW or some other river edge description, the owners would likely argue that well casing is on state property and didn't come with the property.

That will be an expensive decommissioning since the work will be done from a barge. I'm not sure if DOE has the purchasing capacity or expertise to put out a contract for that, but they may need to push a letter to WDFW or COE (navigable channel?) demanding removal.

GH County Commissioners have already been contacted and I heard that they were pushing from their end.
