Every water is different. In its eternal cycle, from the sea to the clouds and as rain via streams and rivers back again, water accumulates many components. Valuable minerals, but unfortunately, more and more concerning substances such as pesticide residues, antibiotics, hormones, and viruses.

Particularly in regions with a large proportion of arable, vegetable, and vineyard cultivation, a large amount of plant protection products containing the active ingredient chlorothalonil was used between 1970 and 2020. Unfortunately, this substance decomposes very slowly and will continue to burden our drinking water for decades.
