UKAS accredited laboratories are accredited against ISO standards for the chemical and microbiological testing of different water matrices.
Unfortunately there is not a single matrix type that has been used for swimming pools, spa pools etc and the accredited laboratory for such water types may therefore be accredited under one of four matrix categories. These are:
- Recreational water
- Swimming Pool water
- Spa water
And for Cryptosporidium also look for drinking water, because this would also be acceptable as the methods are the same and few labs are accredited for swimming pool water.
Please ensure when searching for a laboratory that you consider all these categories for the relevant laboratories.
