Two weeks after its report on the business of influencers and the audience record that followed on the replay, “Complément d’Enquête” is back this Thursday evening with a subject of public interest : tap water. Is it really drinkable ?
The France 2 teams have examined “ hundreds of thousands of drinking water analyzes “. Verdict : one in four municipalities would have known in 2021 the presence of pesticides beyond the authorized limits.
Among the substances detected, the growing presence of metabolites is of growing concern because the consequences on human health of these molecules derived from the degradation of pesticides in the environment are still unknown.
Our colleagues from “Complément d’Enquête” went to meet the inhabitants of several municipalities concerned, including Thierry, nicknamed the fountain worker, who oversees the water supply of Chemilly-sur-Serein (Yonne).
For more than eight years, the inhabitants of the commune have been strictly prohibited from drinking tap water because of the concentration of terbumeton-desethyl (1). Winemaker himself, Thierry admits : “ I was the first to use this product. That’s what they sold us, I thought they were selling us non-harmful products, or at least that we wouldn’t find twenty years later in the water table. »
If the consumption of tap water remains prohibited in Chemilly-sur-Serein, in accordance with the precautionary principle recommended by ANSES, this is not always the case in other municipalities concerned by the presence of metabolites. In Merlieux-et-Fouquerolles (Aisne), it has always been possible to drink tap water despite a concentration of chloridazone-desphenyl (2) well above the norm.
“Additional investigation, is tap water (really) drinkable?”, an investigation by Sébastien Lafargue and Karim Annette, this Thursday, September 22 at 11 p.m. on France 2.
(1) Terbumeton-desethyl is a metabolite derived from terbumeton, a herbicide authorized until 1998 and which was used in particular in the cultivation of vines.
(2) Chloridazone-desphenyl is a metabolite derived from chloridazone, a herbicide authorized until 2020 and which has been used in particular for the cultivation of beets.
