Copper ions and Chloramines Promote Pathogen Growth Under Certain Circumstances

Complexities associated with drinking water plumbing systems can result in undesirable interactions among plumbing components, undermining engineering controls for opportunistic pathogens (OPs). A study examines the effects of plumbing system materials and two commonly applied disinfectants, copper and chloramines, on water chemistry and the growth of Legionella and mycobacteria across a transect of bench- and pilot-scale hot water experiments carried out with the same municipal water supply.
