Dealing with bacterial strains like Legionella is not a simple matter. In fact, there are many steps involved with bacterial control & prevention. It is first mandatory to establish an understanding of the root cause of the outbreaks related to the Legionella bacteria. This entails identifying the source of bacterial growth, physically containing the outbreak and then keeping a close eye on cooling tower contamination going forward. HCTS believes that a Legionella risk assessment is the first & most important step to identifying the risk of Legionella and other bacterial strains that may be present within the given cooling tower system. The Legionella risk assessment is a kind of cooling tower inspection, specifically targeting the possible areas of contamination, which are most commonly found to be on the internal surfaces.

Depending on the results of the risk assessment, HCTS will proceed to carry out disinfections & cleanings of any contaminated components of the cooling tower system.

As shown in the links below, recent research is indicating that outbreaks of the Legionnaires' Disease are often associated with both cooling tower systems, HVAC systems and hot & cold water systems.
