Review of Previous Water Research Foundation Projects on Galvanic Corrosion

Project Paper
  • Effect of Changing Disinfectants on Distribution System Lead and Copper Release, Part 2 (Project #3107) concluded that galvanic corrosion affects lead release but that the galvanic effects are transient and short-lived. 
  • li>Contribution of Galvanic Corrosion to Lead (Pb) in Water after Partial Lead Service Line Replacements (Project #4088b) reported that galvanic corrosion can be a substantial and long-term source of lead release.

p>Consequently, the scope of this review is primarily focused on these two reports, but also includes other relevant work conducted on the topic.
