CERN’s Drinking Water

CERN’s drinking water is monitored, with regular samples being taken and analysed by a certified independent laboratory, which checks on compliance with national and European regulations for safe drinking water. Nevertheless, the drinking water network is very old and occasionally, especially after work has been carried out on the network, the clarity and colour of the water can be adversely affected due to high levels of corrosion in suspension.

Some basic recommendations should always be followed:

• Never use hot water from the tap for drinking or cooking. If you need hot water, then draw water from the cold water tap before heating it.
• Only drink or cook with cold water. Let the cold water run until you notice that the water has become clear.

If you have questions about the quality of CERN’s drinking water, then please contact: Jerome Espuche (GS/SEM), Serge Deleval (EN/CV) or Jonathan Gulley (DG/SCG).
