Corrosion Control in Drinking Water Distribution Using Simple Methods — Introduction to Corrosion Introduction to Corrosion

Corrosion is a natural, thermodynamically driven process that results in a more stable state for the elements and compounds involved. Most metals corrode when they come into contact with drinking water, provided that certain conditions are met. Corrosion is an electrochemical process in which the metal's oxidation potential, its interaction with other conductive materials, and its surface condition play important roles. The water itself and its constituents are also significant, particularly dissolved oxygen, which acts as an oxidizing agent on metals.
