A recent journal article outlines three ways to minimize the risk of Legionella in your water pipes:

  • Releasing copper and silver ions into a hot water system, which helps eradicate Legionella
  • Injecting chlorine dioxide into the water, which over the long term can reduce the presence of the bacteria
  • Point-of-use filtration, which removes Legionella at faucets and other outlets

A combination of the three tactics may be the most effective approach, according to the research, which appeared in the December 2007 Managing Infection Control.

"This article highlights the need for hospitals to . . . maintain water systems to minimize waterborne pathogens, test water for Legionella to make sure the preventive measures are working, and remediate as necessary," says Matt Freije, a Legionella expert who is president of HC Information Resources, Inc., in Carlsbad, CA.

Freije is presenting a Legionella seminar for hospitals in Grand Rapids, MI, on February 12.
