  1. Controlled evalatuion of copper-silver ionization in eradicating Legionella pneumophila from a hospital water distribution system.

    Article - En anglais

    A controlled evaluation was made of the efficacy of copper-silver ionization in eradicating Legionella pneumophila from a hospital water supply.

    Copper-silver ionization units were installed on the hot water recirculation line of one building with water fixtures positive for Legionella species.

    Another building with the same water supply served as a control.

    Legionella species persisted within the system when copper and silver concentrations were<0.3 and<0.03 ppm, respectively.

    When copper and silver concentrations were>0.4 and>0.04 ppm, respectively, there was a significant decrease in Legionella species colonization, but the percentage of water fixtures positive for organisms was unchanged in the control building.
