Corrosion Control: Advanced Treatment & Compliance I: Corrosion Chemistry & OCCT

Advanced electrochemistry of corrosion, galvanic corrosion at dissimilar-metal plumbing connections, pitting mechanisms, and the engineering process behind Optimal Corrosion Control Treatment: desktop evaluation, pipe-loop studies, and coupon testing.

At the Class A level, corrosion control is where treatment chemistry, distribution system engineering, and federal drinking water law converge — and getting it wrong has produced some of the highest-profile public health failures in the history of U.S. drinking water. This first of two advanced guides goes deep into the electrochemistry that drives corrosion and pipe-scale destabilization, the mechanisms behind galvanic and pitting attack at real-world plumbing connections, and the engineering process — desktop evaluation, pipe-loop studies, and coupon testing — that treatment professionals use to actually solve a corrosion problem rather than just monitor it. Part II covers the regulatory framework: the Lead and Copper Rule and its 2021 and 2024 revisions.
