The European Union (Drinking Water) Regulations 2014 (S.I. 122 of 2014) have been updated with some changes to the tests required to ensure water is safe to drink. Amendment SI 464:2017 to the drinking water standard now titles the regulation as "The European Union (Drinking Water) (Amendment) Regulations 2017".
One of the key changes to the regulations is the addition of a test for for Colony Count @22oC (TVC's @ 22oC). From 1st February, all Drinking Water Check Suites will include Colony Count @22oC as standard.
