Is Argostoli Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Tap water in Argostoli, Kefalonia, is generally safe to drink and is supplied under Greek and European Union drinking-water standards. The water may be hard or have a noticeable chlorine taste, but these characteristics do not usually indicate a health risk.
Use bottled water if local authorities issue a temporary advisory, or if you are staying in a property supplied by a private tank or cistern that is not properly maintained. Letting the tap run briefly after a service interruption can help clear stagnant water.
