“…Similarly, copper released upstream of iron pipes could increase iron release [ 270 ]. Any galvanic coupling between two metals in plumbing materials (copper/brass-lead [ 271 , 272 ], copper/iron [ 270 , 273 , 274 ] iron/zinc [ 275 , 276 ], copper/aluminum [ 277 , 278 ], copper/zinc [ 271 , 279 ], copper/magnesium [ 280 ]) has the potential to enhance corrosion and cause changes to water quality parameters relevant to corrosion and OP growth [ 235 , 281 ], dissolved oxygen (DO) [ 273 ], metal concentrations [ 271 , 272 ], and disinfectant residual concentration. These reactions also create microenvironments of very high or very low pH [ 235 , 238 ].…”

Growth of Legionella pneumophila and other opportunistic pathogens (OPs) in drinking water premise plumbing poses an increasing public health concern. Premise plumbing is constructed of a variety of materials, creating complex environments that vary chemically, microbiologically, spatially, and temporally in a manner likely to influence survival and growth of OPs. Here we systematically review the literature to critically examine the varied effects of common metallic (copper, iron) and plastic (PVC, cross-linked polyethylene (PEX)) pipe materials on factors influencing OP growth in drinking water, including nutrient availability, disinfectant levels, and the composition of the broader microbiome. Plastic pipes can leach organic carbon, but demonstrate a lower disinfectant demand and fewer water chemistry interactions. Iron pipes may provide OPs with nutrients directly or indirectly, exhibiting a high disinfectant demand and potential to form scales with high surface areas suitable for biofilm colonization. While copper pipes are known for their antimicrobial properties, evidence of their efficacy for OP control is inconsistent. Under some circumstances, copper’s interactions with premise plumbing water chemistry and resident microbes can encourage growth of OPs. Plumbing design, configuration, and operation can be manipulated to control such interactions and health outcomes. Influences of pipe materials on OP physiology should also be considered, including the possibility of influencing virulence and antibiotic resistance. In conclusion, all known pipe materials have a potential to either stimulate or inhibit OP growth, depending on the circumstances. This review delineates some of these circumstances and informs future research and guidance towards effective deployment of pipe materials for control of OPs.

“…The process of galvanic replacement of silver on the aluminum surface begins from the nucleation at the first seconds almost without an induction period [23] , [34] . After that, the formed nanoclusters grow from the formation on the surface of the precipitate, the morphology of which depends on the conditions.…”
