Water quality & legionella assessment
What is Legionnaires’ disease?
Legionnaires’ disease is a potentially fatal
pneumonia caused by legionella bacteria. Infection is caused
by breathing in small droplets of water contaminated by the bacteria. The
disease cannot be passed from one person to another. Everyone
is potentially susceptible to infection.
Where is legionella found?
Legionella bacteria are common in natural water
courses such as rivers and ponds. Since legionella are
widespread in the environment, they can contaminate and grow
in other water systems such as cooling towers and hot and cold
water services. They survive low temperatures and thrive
at temperatures between 20°c - 45°c if the conditions
are right, e.g. if a supply nutrients is present such as rust,
sludge, algae and other bacteria.
What are my duties under the law?

Approved Code of Practice, you have to consider the risks from
legionella that may affect your staff or members of the public
and take suitable precautions. As an employer or a person
in control of premises (e.g. landlord) you must:
