Legionella Risk Assessment in Water System

Hi,

I am looking for a sample Water risk assessment for Legionella in Water supply system.

Can anyone provide a guidance / sample to conduct legionella risk assessment.

Many thanks,

Things to consider regarding legionella to compare against your specific water system using a risk x likelihood matrix are:

• tendency to form droplets and aerosols e.g. still water would be low and aerosol or a lot of spray would be higher risk
• conditions of water e.g. potable, sterlised (UV, RO etc. will give a different risk rating), or known to be contaminated would be higher risk
• water temperature (one of the most crucial factors to consider) if the water is in the danger zone it will be higher risk (zone is approx. <20°C and approx. >50°C
• water flow rate e.g. legionella likes stagnant water so this would be a higher risk on the rating
• other factors such as population, density and susceptibility of exposed individuals

The total rating after adding all these risk ratings can be interpreted to then determine control measures and testing frequency
