Our Legionella sampling kits contain all supplies and instructions needed to effectively collect samples and return the samples to our laboratory for analysis.

Legionella bacteria in a facility’s water system can potentially lead to an outbreak of Legionnaires’ disease. Legionnaires’ disease is a serious pneumonia type respiratory illness. According to the CDC, 1 in 10 people who develop the disease will die. The only way to know for sure that Legionella bacteria are not present in a water system is to test the water. The CDC provides guidance on Legionella Control including for routine sampling and laboratory analysis. Review at CDC Control Toolkit Routine Testing.
