Range across supply zones: 164–286 mg/L.
Lamía is served by the municipal water utility ΔΕΥΑ Λαμίας. Its 2026 laboratory results give a median of 174.5 mg/L as CaCO₃, with samples ranging from 164 to 286 mg/L, so hardness varies between sampling points. The surrounding region has a lot of limestone, which is the usual reason for hard water here, though we have not confirmed the exact sources feeding each zone. Check the figure for your own street before sizing a softener.
Greek utilities report total hardness in mg/L CaCO₃.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
