Possible problem areas in drinking water

When the drinking water is released into the pipeline network by the water supply company, the quality of the water is in principle very high and should meet the requirements of the Drinking Water Ordinance. Unfortunately, on the long way to the household and finally to the drinking glass, a lot can happen and have a significant impact on the quality - including making the drinking water unsuitable for consumption.

Common problem areas are

  • Nickel, zinc or chrome pollution from fittings

  • Lead, copper or iron loads from cables

  • Increased sodium levels when using water softening systems

  • Nitrate and phosphate excesses, especially in house wells, e.g. B. through inputs from agriculture (fertilizer)

  • Legionella infestation in boilers, hot water pipes and tapping points (shower head etc.)

  • Microbial contamination from contamination in pipes and tapping points

All of this shows the need to have the drinking water at home at the tapping point (e.g. kitchen faucet) independent, qualified laboratories to have checked.

In some cases, the population shows that they are not sufficiently informed about the quality of drinking water - this is confirmed by the EU study on drinking water quality, where just under half say they are sufficiently informed about the quality of drinking water.
