Range across supply zones: 51–55 mg/L.
For Moguer, SINAC (the Ministry of Health's water-supply system) records 52.5 mg/L CaCO₃, with readings from 51 to 55 mg/L as of September 2026. Huelva province is supplied from reservoirs such as Chanza and Piedras and from sandy aquifers near Doñana; this ground holds little carbonate, so the water tends to be soft. At this level scale barely builds up on taps or appliances, and a softener is rarely worth installing.
