Lucile Packard Children's Hospital Stanford

Located in Palo Alto, California, Lucile Packard Children's Hospital Stanford is one of the top pediatric hospitals in the United States.


Legionella was found in the hospital's potable water soon after it was built in 1991. A thorough investigation revealed the municipality to be the source. Facility staff deployed several unsuccessful water treatment methods over a six-month period, including:

  • Whole-system water flush
  • Hyperchlorination
  • Superheat and flush
  • Continuous chlorination and a weekly superheat and flush


After a long unsuccessful effort to eliminate Legionella through conventional disinfection methods and two patient deaths linked to the contaminated water, the hospital partnered with LiquiTech to develop a solution that included:

  • Immediate installation of a LiquiTech® Copper-Silver Ionization System 
  • Several days of onsite system flushing, monitoring, and water testing until negative Legionella levels were achieved

Hospital staff continues to partner with LiquiTech for ongoing service, including maintenance, monitoring, and testing. The hospital has not detected Legionella in its water supply since.


Challenge: Conventional disinfection methods failed to destroy Legionella, resulting in two patient deaths
Solution: LiquiTech mobilized immediately to begin remediation efforts, installing a LiquiTech® Copper-Silver Ionization System
Results: 30+ years without Legionella detected in the hospital's potable water

“I strongly advocate copper-silver technology for the effective and safe treatment against waterborne pathogens, specifically Legionella. Lucile Packard Children's Hospital Stanford has been waterborne pathogen-free since partnering with LiquiTech more than 30 years ago.”

-Michael Zader, Administration Director of General Services, Lucile Packard Children's Hospital Stanford
