Abstract
Two related approaches are provided to controlling the relative permeability of ground water and gases developed in deep well anodic installations. The central metallic anode is encased and protected by a semi-permeable conductive cementaceous sheath, using as the sheathing material any of a number of compositions having the desired properties of permeability and conductivity. Alternatively, a conductive but impermeable anode is used in conjunction with a semi-permeable backfill material in a bore hole of a deep well anode installation, thereby achieving the same desired ends of controlling the relative permeability of water and gases in the installation.
