Legionella Testing & Control

Legionella Testing

Legionella pneumophila in Water Systems

Legionella pneumophila is a waterborne bacterium that can cause Legionnaires’ disease, a severe form of pneumonia, and Pontiac fever, a milder flu-like illness. The bacteria proliferate in man-made water systems where water temperatures typically range between 25°C and 45°C, particularly in stagnant water and biofilm.

Routine Legionella testing is essential for protecting public health, meeting regulatory requirements, and reducing the risk of outbreaks.

Where Can Legionella Grow?

Legionella may colonize many engineered water systems, including:

• Hotels and resorts
• Hospitals and healthcare facilities
• Cooling towers
• Domestic hot water systems
• Spa pools and jacuzzis
• Thermal baths
• Swimming pools
• Decorative fountains
• Air-conditioning systems
• Water storage tanks

Why Legionella Testing Is Important

Regular monitoring helps to:

• Protect public health
• Detect contamination before outbreaks occur
• Verify the effectiveness of water treatment and disinfection
• Support risk assessment and water safety plans
• Demonstrate regulatory compliance
