Impressed current cathodic protection systems are widely used to provide corrosion protection for buried steel structures. Application of these systems includes installation of metallic anodes underground that gradually dissolve over the service life of a groundbed. This presentation will discuss field monitoring of groundwater quality in the vicinity of a shallow anode bed for possible soluble metal contamination arising from the dissolution of the anodes or other processes. To date soluble metal ion concentrations and hydrogeological modeling support the view that metals such as chromium, nickel, boron, copper and vanadium released in soluble form by dissolution of the anode do not pose a threat to groundwater quality.
