This British Standard gives recommendations and guidance on the
sampling of water and related materials for determination of the
presence of organisms of the genus Legionella. It is applicable to
sampling artificial water systems and also gives methods for sampling of
biofilms and sediments that might be present in water systems. Some of
the same sampling principles can be applied to natural water systems.
The standard is applicable to both sampling for routine monitoring
and in outbreak investigations. For the latter, recommendations and
guidance on the selection of sampling points are given. The rationale
for the selection of sampling points for particular situations is also
discussed.
This British Standard is intended for use by all those involved in water
sampling for legionellae including the persons taking samples on site
and their employers.
