Jyväskylä's water is run by Alva-yhtiöt, not by a company called Jyväskylän Vesi. Its page, updated in June 2026, gives 0.2 to 0.5 mmol/L (1.1 to 2.8 °dH) for the general supply. The Janakka-Kaivovesi works area is harder at about 0.6 to 0.7 mmol/L (3.4 to 4.0 °dH). The page prints ranges only, so no single measured value is available.
Finnish waterworks report hardness in °dH; most supplies are soft.
