Der Median ist der mittlere Wert aller Messungen des Jahres. „-/-“ bedeutet, dass alle Einzelstoffe unter der Bestimmungsgrenze lagen; die Seite zeigt dann eine Obergrenze aus den Bestimmungsgrenzen. Die Berliner Wasserwerke arbeiten im Verbund, aus dem Hahn kommt meist Mischwasser mehrerer Werke. Für Berlin liegen 9 Werke bzw. Messstellen vor (Wasserwerk Beelitzhof, Wasserwerk Friedrichshagen, Wasserwerk Kaulsdorf, Wasserwerk Kladow, Wasserwerk Spandau, Wasserwerk Stolpe, Wasserwerk Tegel, Wasserwerk Tiefwerder, Wasserwerk Wuhlheide). Die PFAS-Kennzahl der Seite stammt aus „Wasserwerk Tegel“, der Messstelle mit dem höchsten PFAS-4-Wert; die übrigen stehen in der Tabelle.
