Apparently there is a misunderstanding over whether a property owner also "owns" the groundwater flowing beneath his or her land. He or she does not, but Russell Harding, former Michigan DEQ Director, thinks so. With his usual perspicuity. If he were right, there wouldn't have been a Nestle water heist case in Michigan. Property owners have a right to use, not ownership of both groundwater and surface water.
So fix the Compact by making that clear.
