We have put together the image below with guidance, provided by HSG 274 Part 2, on action to take if water sampling results show that legionella bacteria is found in your water system. For healthcare premises, there are special considerations that should be taken due to vulnerable patients. Any detection of legionella, even if it is less than 100 cfu/l, should be followed by the system being resampled to aid interpretation of the results in line with the monitoring strategy and risk assessment.

Carrying out effective water hygiene monitoring tasks ensure that the legionella risk is kept minimal. Speak to one of our expert consultants today for advice on what tasks you require to keep your premises safe and compliant with HSE regulations.
