Abstract: Provided are systems and methods for preventing corrosion, and lead and iron contamination in potable water piping systems comprising lead, non-electrically conducting, and/or iron pipes. A sacrificial/potential anode, made of a material, such as a metal or metal alloys less noble than iron, e.g., zinc, aluminum, magnesium, and/or alloys thereof, is electrically attached to the potable water piping system. Alternatively, an active cathodic corrosion prevention system may be used. The active cathodic corrosion protection system comprises an independent source of DC power, a voltage controller and a non-sacrificial or a sacrificial/potential grounding anode. The negative terminal of the voltage controller is connected to the potable water piping system. The interior surface of the lead and/or iron pipe is maintained at a voltage and/or potential above the reduction potential of the redox reactions between the disinfection chemicals and the interior surfaces of the lead and iron pipes.

Abstract: The deterioration of reinforced concrete structures by galvanic corrosion is a well understood problem, particularly as it affects roads, bridges, parking garages and buildings that use reinforcing steel in their construction. Galvanic cathodic protection is typically provided for such reinforced concrete structures using embedded sacrificial anodes, such as zinc, aluminum, and alloys thereof. Disclosed herein is an anode assembly (10) for cathodic protection of a reinforced concrete structure. The assembly comprises at least one sacrificial anode member (12). The anode member is covered with an ionically-conductive covering material (14) into which is bound an electrochemical activating agent at least partly covering the sacrificial anode member. One side (26) of the ionically-conductive covering material is configured to conform closely and securely to a steel reinforcing bar. The conforming side has a non-conductive barrier (16) as an integral part of the covering material. An electrical connection is established between the anode member and a ferrous reinforcing bar (20) using conductive wires (18).
