Why Your Business Needs Legionella Risk Management

Any water system could become a common source for Legionella bacteria to grow under certain environmental conditions. Common places to find Legionella bacteria are ponds, rivers, and lakes. However, outbreaks of Legionnaires’ disease rarely originate from these sources.

Legionnaires disease and illness outbreaks can occur from exposure to Legionella growing in purpose-built systems such as:

  • Hot water systems
  • Cold water systems
  • Spa pools
  • Cooling towers

The water in systems like these is usually maintained at a specific temperature likely high enough to encourage growth. The below places can also propose a risk for Legionella bacteria growth.

  • Emergency showers
  • Humidifiers
  • Air washers
  • Ornamental fountains
