Sounds like it's bad!
Of course, you have to take a closer look. In Germany and Austria, the water suppliers mostly do a great job and water of perfect drinking water quality (according to the currently applicable parameters) is released from the waterworks into the pipeline network. But there are also a lot of challenges:
- Groundwater has the highest quality in the German-speaking area. In the areas where surface water is used to produce drinking water, the question is whether the parameters prescribed in the Drinking Water Ordinance are sufficient or whether these should be expanded. Think of the many substances that humans bring into the (water) cycle (e.g. drug residues, etc.).
- Look at the graphic (comparison of cities). No waterworks emit lead and nickel into the pipeline network. Nevertheless, it can be detected in households. At the point of use, there is still no quality control. The point of control of the drinking water quality still takes place on the public side at the point of delivery - i.e. in the waterworks. A control at the point of removal would be the correct control point here. The European Drinking Water Directive 98/83 / EC came into force in 1998 and provides for the inspection of the drinking water quality to be complied with there - at the POINT OF TAKING - i.e. at the TAP. Since the public control can probably not be organized sensibly here (personnel and independence of the control body), a set of rules that prescribes and regulates the control on a private basis would make sense. There are enough engineering firms, civil engineers, and laboratories that could do this job.
The EU Commission also wants more tap water to be drunk than, for example, mineral water. Drinking water is always good and healthy, but this is not about comparing the quality of drinking water and mineral water, because strictly speaking, mineral water is of higher quality than tap water - it can only be processed to a very limited extent (iron and manganese), it must not be chlorinated (Keyword: safety chlorination), does not flow long distances through pipes (must be bottled directly from the source) and it must have positive nutritional properties (minerals and trace elements).
So this is about a packaging topic and the production methods, but also the legal basis, need to be improved!
