Legionella Resources

Legionella Information

The last several years have brought about some profound changes to the issues facing facility managers and directors.  Among them is managing risk associated with proper cooling tower care and the potential for Legionnaires Disease.  The Center for Disease Control (CDC) reports confirm that the frequency of cases continues to rise each year and the Center for Medicare & Medicaid Services (CMS) and other regulatory agencies have made it clear that many water systems within facilities should be taking a proactive approach to managing this risk.

In response to an industry-wide plea for standard measures for Legionella control, the Association of Water Technologies (AWT) recently issued guidance.  AWT is widely regarded as the water treatment industry’s primary resource for credible and effective guidelines. We feel that it is important to communicate their guidance to you.

AWT's Position Statement & Guidance on Legionella

It’s clear that every cooling tower system is different in design, risk for contamination and exposure to human life.  Accordingly, Chardon establishes programs with the flexibility to meet the diverse needs of the facilities while recommending the practices outlined in AWT’s guidelines.  In addition to our long-standing approaches to service, optimization, and scale and corrosion management, the guidance from AWT addresses biological control and documentation up to the level deemed necessary to control Legionella growth within your cooling tower system.  It provides testing and remediation procedures as well as guidance on maintenance practices needed to meet the standard.
