Evian bottled water, produced by the French company Danone, is supposed to be so pure that scientists will calibrate their measuring devices with it. But new data from Swiss researchers finds it to be contaminated with a toxic fungicide. “The fact that even the Evian springs in the French Alps, which are hardly affected by humans, contain pesticide residues is alarming and shows the far too careless handling of these substances,” Roman Wiget, president of the international drinking water association AWBR told the German-language Swiss weekly. The answer is not to simply ban another toxic pesticide, only to be followed by another toxic pesticide, but foundational changes to agriculture and land management with a shift to organic practices.
Danone claims that the purity of Evian bottled water comes from its source in Cachat Spring at the base of the French Alps in the town of Évian-les-Bains, France, where it is “[p]rotected under a fortress of geological layers built by glaciers 30,000 years ago, it slowly travels through natural snowy, glacial rocks naturally filtering it.” Evian publishes results of water quality testing, supporting its claims of water high in natural minerals and lacking detections of synthetic chemicals.
Findings of the transformation products of the fungicide chlorothalonil, which is unlikely to have been used near the source of Evian water, demonstrate the fact that pesticides cannot be controlled. Evian, as a purveyor of “pure” water for people who are concerned about the contamination of their own local water supplies, should take actions to protect its water.
Chlorothalonil is a dangerous, highly toxic pesticide. As a probable human carcinogen, there is no safe dose. The transformation products found in Evian bottled water can be removed by carbon filtration, but such treatment results in contaminated carbon and places the burden of removal on Evian, rather than the chemical companies. Although other pesticides have not been found so far in Evian's water, there is no reason to believe that the Cachat Spring is safe from contamination from other chemicals as long as chemical-intensive agriculture and land management is the norm.
As of 2020, chlorothalonil use is banned in the EU. However, long-distance transport is evidently responsible for the contamination of Cachat Spring water, and the presence of currently used pesticides in the Arctic is evidence of cause for concern. It is particularly worrisome that groundwater, as a principal source of drinking water, is increasingly found to be contaminated with pesticides, even those used far from the site where the groundwater is withdrawn. Action is required worldwide, and we are urging Danone to become a leader in protecting the environment and its brand.
Evian should protect the purity of its water by supporting Beyond Pesticides' international campaign to transition to organic agriculture. This effort not only protects groundwater, but it confronts the apocalyptic challenges we face as a global community with the climate crisis and the devastation of biodiversity. In the short-term, Danone should protect its consumers and its integrity by using filtration to remove chemical contaminants and labeling when they cannot be removed. However, using filtration is only a limited short-term fix that does not address underlying chemical dependency on hazardous and persistent pesticides that are not needed for land management.
