Abstract
Determines the effect of changing disinfectants (from free chlorine to chloramines and vice versa) on metals leaching rates and leaching levels from lead, brass, and copper distribution system components. Also examines the relative impact of oxidation and reduction potential of changing disinfectants and their potential impact on the characteristics of protective scales formed on brass and other metal plumbing materials. Studies the effects of galvanic coupling on metals release. Part 1-Literature Review was published in 2006 (Order 91152). Part 2-Research Results was published in 2010. (Order 3107)
