Intermittent Use of Copper-Silver Ionization for Legionella Control in Water Distribution Systems: A Potential Option in Buildings Housing Individuals at Low Risk of Infection

This study, published in Clinical Infectious Diseases in 1997, evaluated the success of copper-silver ionization in eliminating Legionella from a hospital contaminated with the bacteria on a short-term basis as well as its residual effects after the system was deliberately shut off and relocated.
