Yes, tap water in Amalfi—and across most of Italy—is completely safe to drink and meets the strict safety regulations set by the European Union. The water in the Amalfi Coast region often comes from high-quality mountain springs in the Apennines and is tested multiple times daily for contaminants. You will notice many public fountains (called nasoni in larger cities) where the water flows continuously and is safe for refilling your bottles. However, because of the region's historic infrastructure, the water can be quite "hard," meaning it has a high mineral content (calcium and magnesium) that may taste different or "stronger" than what you are used to at home. It is a peer-to-peer "pro-tip" to look for the sign "Acqua Potabile" (Drinkable Water); if you see a sign that says "Acqua non potabile," do not drink it as it is likely recycled water for irrigation or fountains.
