Controlling Legionella Case Study: Chlorine Dioxide vs. Copper-Silver Ionization

In 2009, an outbreak of Legionnaire’s Disease hit a large Georgia hospital, affecting six wards, and resulting in the closure of 10% of their patient beds. After trying several solutions, including installation of continuous chlorine dioxide systems and plumbing infrastructure upgrades, the hospital still tested positive for Legionella.  

In 2023, the hospital partnered with LiquiTech to install a LiquiTech® Copper-Silver Ionization System to control the Legionella contamination and reduce the risk of future disease outbreaks.  

Within just two months of installing copper-silver ionization, the Legionella positivity rate dropped from 100% to 11%, with the next round of testing showing 0% positivity. Through its ongoing service partnership with LiquiTech, the hospital has successfully maintained control of the Legionella contamination.  

By choosing the right technology and ensuring ongoing maintenance, the hospital’s priorities of protecting their staff and patients and controlling waterborne pathogens were achieved.
