Why Test for Legionella?

Legionella bacteria are found naturally in freshwater environments, but can become a serious health threat when they grow and spread in manmade water systems like:

• Cooling towers

• Indoor plumbing

• Pools and spas

• Decorative fountains

When inhaled in aerosolized water droplets, Legionella can cause severe illnesses such as Legionnaires’ Disease or Pontiac Fever. People at higher risk include those with weakened immune systems, chronic respiratory conditions, the elderly, and smokers.

According to the CDC, 9 out of 10 cases of Legionnaires’ Disease could be prevented with proper water management. Routine testing is a critical component of any prevention plan.
