The utility GE.S.E.SA runs the water service in Benevento; the page we used does not say where the water is drawn; the valley around Benevento lies in a region of limestone ranges. The utility reports 230.0 mg/L CaCO₃ across 3 supply zones, with readings from 180.0 to 280.0 mg/L, which counts as very hard water. Values differ across the area, so check your own address before buying a softener; expect scale on kettles, shower heads and in the water heater, and descaling about as often as a hard-water kitchen requires.

Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.
