UAB Druskininku vandenys lists 3.73 mg-eq/L total hardness (the same quantity as meq/L) for the Druskininkai III wellfield in its 2026 hardness PDF, about 187 mg/L CaCO3. The same table prints calcium at 55.1 mg/L and magnesium at 11.9 mg/L for that wellfield. Other wellfields in the file serve other settlements and are not counted here, and no sampling date is printed. Lithuanian rules set no hardness limit, so the practical effect is moderate limescale on kettles and heaters.
Lithuanian suppliers report total hardness in mmol/L.
