The effects of switching monochloramine for chlorine in disinfection

This work was commissioned under the CREW call down service. The object of the project was to carry out a literature search on the effects of switching from chlorine to monochloramine for water disinfection, specifically with regards to the effects on lead and copper corrosion. Information was sought on current understanding of disinfectant choice on lead and copper corrosion; the lessons learned from a Washington case study, and guidance on the appropriate sampling protocol for lead and copper measurements.
