Anyone who produces fresh spring drinking water at home saves themselves the hassle of carrying bottles, contributes to reducing environmental pollution, and can spare themselves contamination from harmful substances in water through PET bottles. (PET: Polyethylene terephthalate, a plastic from the polyester family).
The TV magazine "MEX" is a business and consumer magazine of Hessian Broadcasting. In May 2017, the broadcaster aired this 4-minute feature about water contamination in "PET" bottles. Plasticizers in plastic are hormonally active. Prof. Schönfelder (University of Würzburg) discusses the consequences of hormone-active substances for humans. Reproduction is particularly affected. Market leader Gerolsteiner as well as the Association of German Mineral Springs refused to grant an interview on the topic. The authorities do not remove PET bottles from circulation, even though manufacturers refuse to disclose their contents. For Prof. Schönfelder, this is completely incomprehensible, since no one knows how these substances kept secret by industry will affect the population.
Hormones and also microplastics are now found even in tap water. Consumers of water from truu refining systems are protected from these and many other harmful substances.
