Your neighbourhood matters more than your city
The water in Naples runs from 160 ppm to 770 ppm — a spread of 610 ppm that crosses Medium → Hard. That is not imprecision: a city this size is served by several waterworks, and the average describes no tap in particular. Check which works supplies your street before you trust a city figure, ours included.
Against the SCA target zone
At its softest, Naples sits 1.4× above the top of the zone the SCA Water Chart marks as its target (2.8–6.2 °dH). Read that as a distance, not a verdict: the chart maps taste outcomes, it does not grade cities.
The same number, three ways

- 160–770 ppm
German utilities publish °dH, French and Italian ones °f, British and Irish ones ppm CaCO₃. Same water, three conventions — worth knowing if you compare your city with one abroad.
Of the 47 cities we publish, Naples ranks 1st by hardness.
