A recent investigation has revealed extremely high concentrations of microplastics in the mineral waters Contrex and Hépar, brands under Nestlé Waters. Measurements indicated levels of 515 microplastic particles per liter in Contrex and 2,096 particles per liter in Hépar, amounts reported to be between 51,000 and 1.3 million times higher than typical findings. The Office français de la biodiversité noted that some water sources for these brands contain microplastic levels 3,000 times above recommended limits. The contamination has been linked to illegal waste dumping in the Vosges region, although Nestlé Waters denies any contamination and maintains that its waters are safe to drink. The findings were initially reported by Mediapart and have sparked concern about the purity of these widely consumed mineral waters in France. While the connection between Nestlé Waters and the pollution is under preliminary investigation, the report has drawn attention to environmental and public health implications associated with microplastic pollution in bottled water.
