Berliner Wasserbetriebe - water analysis data from the waterworks

The annual median values ​​for 2016 of the analysis data for the drinking water from the 9 waterworks of the Berliner Wasserbetriebe are shown. Drinking water is the best controlled foodstuff in Germany. In order for water to be designated as drinking water and used as food, it must comply with the German Drinking Water Ordinance (TrinkwV). State-of-the-art analytical methods are increasingly making it possible to determine the smallest traces of substances in water, so that the number of detectable organic components in the water matrix is ​​constantly increasing. With the improvement in analytics, more and more substances can gradually be detected analytically. These substances are documented under the term "trace substances". The concentrations are usually in the nanogram range (1 billionth of a gram) per liter. Put simply: a lump of sugar in Wannsee. The Berlin water meets the requirements of the Drinking Water Ordinance. The measured values ​​are annual median values. The median is a statistical mean. Unlike the average, the median is the exact middle value in a list of numbers sorted by size. An example: In the series of numbers 2,4,5,8,9 the median is 5.
