This study focuses on the application of electrochemical corrosion rate measurement and solid surface analysis approaches to understanding drinking water copper corrosion. Applying electrochemical approaches combined with copper solubility measurements, and solid surface analysis approaches are discussed. DC polarization (DCP) and Electrochemical Noise (ECN) measurements were carried out to obtain Stern-Geary constant and noise resistance, respectively. ECN has the advantage in that corrosion behavior can be monitored as a function of extended periods of time without the need to apply an artificial potential that can potentially alter the metal surface in an unnatural way. ECN allows for the prediction of how natural films on the corroding metal surface are impacted by changing water quality conditions.
