Corrosion Control: Operator Fundamentals

An entry-level introduction to why corrosion control matters, the basic electrochemistry behind pipe corrosion, how to recognize red water and blue-green staining in the field, and the fundamental treatment strategies operators use to protect customers.

Every red-water complaint, every blue-green stain around a bathroom faucet, and every trace of lead detected in a customer's glass of water traces back to the same underlying process: corrosion. As a Class D operator, you are often the first person to hear about these problems, and you sit on the front line of a much larger public health issue — because the metal quietly dissolving out of pipes and household plumbing can include lead, a neurotoxin with no safe level of exposure, especially for children. This guide introduces the basic chemistry of corrosion, how to recognize its warning signs in the field, and the fundamental treatment strategies operators use to keep water non-corrosive from the treatment plant all the way to the kitchen tap.
