Legionella testing is the only way to determine if your cooling tower system is clean and it gives building owners, operators, managers and landlords an opportunity to find out if their system contains high levels of Legionella and to prevent the spread of Legionnaires’ disease. Legionnaires’ disease is most often seen in warmer and wetter summer months when the Legionella bacteria may rapidly increase in cooling towers and spread through water droplets leaving the tower. Legionella is common in the environment and grows best in the warm water.
Therefore, when testing cooling towers, there is a likely chance of finding it, although it may include organisms that are no longer active. If it is found, it is important to know how much legionella is there. If the amount of the bacteria is high, people are more likely to be exposed and could become ill.
If elevated levels of bacteria are measured, building owners and operators should take the corrective measures to clean and disinfect the unit(s). Then they will need to retest it to confirm that that the problem has been addressed. There are three popular methods to test for Legionella:
Testing samples should be consistent and taken in the same place, in the same way, every time. It is recommended for cooling towers that water samples, which are free from sediment be collected from the tower basin at the furthest most point away from the make-up-water. Keep in mind, the best prevention for legionellosis is maintenance of the water systems in which Legionella grows.
