Could 5G pose a potential health risk-

The purpose of this study was to determine if microorganisms could be considered a significant contributor to distribution system corrosion where year-round water temperatures remain near zero degrees Celsius. Initial evidence indicates that a heterogeneous population of potentially corrosive microorganisms were present in untreated supply water, treated water and corrosion tubercles. This included sulfite-reducing bacteria (Clostridium species), sulfate-reducers; iron-reducing bacteria (Bacillus species, Clostridium sp., Escherichia coli, Enterobacter aerogenes, Klebsiella oxytoca, Klebsiella pneumoniae, Pseudomonas aeruginosa, Pseudomonas cepecia, Pseudomonas fluorescens), sulfur-oxidizing bacteria (Thiobacillus thiooxidans, Thiobacillus thioparus), iron-precipitating bacteria (Leptothrix, Gallionella, Sphaerotilus), sulfate-reducing actinomycetes and iron-reducing fungi (Penicillium, Rhizopus, Aspergillus). Corrosion tubercles contained greater numbers of coliforms than did the untreated supply or treated water. The ability of corrosion tubercles to sustain a diverse population of direct and opportunistic pathogens, able to participate in the corrosion process, may be an unrealized vector in the transmission of certain waterborne diseases to potential risk groups. In addition, corrosion tubercles may serve as a habitat for certain taste and odor-producing actinomycetes and fungi in treated water supplies. The ecology of these microorganisms, their influence on the corrosion process and the potential health impact needs to be investigated further.
