Environmental impact

Members of the environment team take some samples of water in the Allondon river to monitor the water quality.


More than 100 CERN monitoring stations are constantly checking the quality of CERN’s water effluents before release as well as emissions into the atmosphere including ionising radiation. The quality of neighbouring rivers, soil, and agricultural products is also examined and tested. Roughly 2000 samples are taken and 7000 laboratory analyses are conducted each year by the CERN environmental laboratory.
