Microbiological Sampling - UKAS Sample results
Domestic water systems are supplied with water for potable use, so ACoP L8 advises that regular microbiological sampling is not required.
Where potable (drinking water) water is stored, BS6700 sets out a regime where 6 monthly microbiological activity is measured.
ACoP L8 recommends that sampling for Legionella should be carried out when:
- Systems treated with biocide where storage and distribution temperatures are outside acceptable parameters.
- In systems where the control measures are not consistently achieved.
- Where a Legionella outbreak is suspected.
- High risk areas where the users of water systems are in a highly susceptible category e.g. hospital wards etc.
All testing is carried out by a UKAS certified lab.
