Risk Factors in Cooling tower systems:

• Presence of water
(especially if stagnant, for example, ‘dead legs’ or system not in use)

• Presence of Legionella

• Legionella concentration

• Presence of other heterotrophic bacteria

• Presence of protozoa and algae

• Presence of nutrients

• System size
(surface area available for biofilm development (compared with water volume)

• Presence of biofilm

• Water quality:

– cleanliness
– pH
– presence of corrosion products
– presence of scale and fouling
– conductivity/Total Dissolved Solids
– control limits out of range
– suspended solids
– control of water treatment chemicals, bleed

• Water temperature

• Characteristics of make-up water

• Direct sunlight

• Physical condition of system

• Microbial control program

• Open system

• Aerosol generation

• Mode of operation

• Intermittent operation

• Seasonal usage

• Drift elimination

• Aerosol dispersion

• System location
(distance to other cooling water systems, air intakes and passers by).
