Nestlé claims to have “intensified monitoring” of its French drilling. French health agency Anses recommended "reinforced surveillance" of the Swiss giant's water catchment sites.
At the start of the year, the group admitted to having used disinfection treatments in France and Switzerland in order to “guarantee the food safety’ of its products. However, such treatments are prohibited to claim the qualification of natural mineral water. The group is now challenged to maintain the quality of its water, with fewer tools at its disposal, and while climate change disrupts groundwater recharge.
