Not all water is the same.
Depending on its origin, tap water is also more or less contaminated.
Studies have shown that it contains many different substances that should not be ingested on a long-term basis: Heavy metals (lead, copper, nickel, mercury, cadmium). Acrylamide, benzene, boron, bromate, chromium, cyanide, nitrate, selenium, uranium, antimony, arsenic or benzopyrene, suspended solids and residues from agriculture (chlorothalonil) and medicines such as birth control pills.
All the water used in our products goes through 3 purification stages:
1. demineralization system (removes metals)
2. microfiltration 5µ (removes suspended solids)
3. activated carbon filter (removes organic impurities from medicines and agriculture etc.)
This enables us to guarantee impeccable quality in our own products. Above all our CDS (chlorine dioxide solution).

Groundwater is under pressure. As various studies have shown, the quality of our drinking water is also at risk - especially in regions with intensive agricultural use. Consistent implementation of effective measures to protect groundwater is needed to avert this risk.
The quality of our drinking water is at risk - especially in regions with intensive agricultural use.
Switzerland is not used to news like this: at the end of January 2020, the canton of Solothurn announced problems with the quality of its drinking water. The authorities announced that 160,000 people were being supplied with water that did not meet the legal requirements. Although there is no immediate danger to health, it will take years or even decades for the residues of the pesticide chlorothalonil to disappear from the groundwater. As almost all large groundwater wells in the canton are contaminated, Solothurn's water suppliers are facing major challenges. In future, drinking water may have to be sourced from outside the canton via new pipes.
Almost two thirds of the population without safe drinking water! No quick solutions in sight! Costly new infrastructure needed! This news prompted spiteful online comments: "Who are these well poisoners?" asked one concerned reader, for example. However, Solothurn's concerns about the quality of its drinking water are not unique. The Seeland Water Association, for example, from which the Bernese towns of Biel and Lyss, among others, obtain drinking water, had to close four out of five groundwater wells at the end of 2019 due to pesticide residues. "We have lost 70 percent of our capacity and therefore have a serious problem," explains Roman Wiget, member of the Board of Directors of this water association, which supplies around 100,000 people.
Problematic decomposition substances
The unusual drinking water problems were not caused by the use of a new pesticide, but because the authorities took a closer look at a substance that has been in use for decades. Chlorothalonil has been used by farmers since the 1970s to protect vegetables and fruit from fungal infestation. However, it is only since 2019 that groundwater has been specifically searched for degradation products of this substance. Based on new findings, the Federal Food Safety and Veterinary Office (FSVO) has classified chlorothalonil residues as "relevant" for the quality of drinking water. In the meantime, stricter limits for the degradation products of the pesticide have come into force and chlorothalonil itself has been banned.
"Due to the new limits, various groundwater sources are now considered contaminated," explains Michael Schärer, Head of the Water Protection Section at the FOEN. "According to initial estimates, the groundwater wells affected supply around 1 million inhabitants with drinking water." Many of these wells will have to be shut down in the coming years. This would mean a "severe reduction in the security of supply" in the affected regions and would jeopardize the decentralized organization of the Swiss drinking water supply.
