2.15 Drinking water quality: Requirements claimed by national and international standards (Hartmut Bartel)
Drinking water quality: Requirements claimed by national and international standards: Drinking water is not an ordinary consumer good and is subject to local peculiarities. When the raw-water is treated into drinking water, its quality should be as high as possible. The pollutants from the raw-water and the residuals from the treatment-chemicals must be minimised. Drinking water must be safe for a person to consume 2 litres per day over a lifetime. The limit values or maximum content levels of parameters are only a (small) part of the requirements; a multibarrier system must protect the drinkingwater quality. A process control system has to ensure the quality between the product control analyses.
