Complementing the regular information to consumers, drinking water quality has in three year cycles to be reported to the European Commission. The Commission assesses the results of water quality monitoring against the standards in the Drinking Water Directive. After each reporting cycle the Commission produces a synthesis report, which summarises the quality of drinking water and its improvement at European level.
The European Commission adopted on 16 June 2014 a Synthesis Report on the Quality of Drinking Water in the EU examining the Member States' reports for the period 2008-2010. The report COM(2014) 363 final summarises the information provided by 27 Member States.
As referred to in the synthesis report, technical reports which contain detailed fact sheets per Member State are also available:
The reporting exercise for the period 2011-2013 is ongoing. Further information and guidance can be found here.
