SINAC data from the Ministry of Health for June 2026 put Arroyo de la Encomienda at 144 mg/L CaCO₃. Water in this part of Valladolid combines Duero intakes with wells in páramo terrain, which holds limestone and gypsum, hence high and variable hardness. Limescale starts to show on glass and coffee machines, though the effect at home is moderate.
