When and How to Evaluate Corrosion Control Treatment When Conditions Change

Abstract

This project created a guidance document based on science and utility experience for state regulators and water systems recommending when and how to conduct a corrosion control study in anticipation of a treatment change, water quality change, or a requirement/desire to lower lead levels. Detailed case studies and flow charts provide real world insight and actionable steps a utility can take to optimize their corrosion control treatment. Research partner: Mohawk Valley Water Authority. Published in 2022.
