The map of Spain where you can see how healthy the tap water in your town is

DATADISTA launched “El agua de tu pueblo,” a public interactive map using official SINAC data to show nitrate levels in tap water by Spanish municipality.

The map also adds layers for vulnerable zones and aquifers, helping users see where agricultural contamination may pose a higher risk.

It lets citizens check whether their local tap water meets nitrate rules under Spain’s latest drinking-water standards, including Real Decreto 3/2023.

The tool covers municipalities across Spain and uses OpenStreetMap as part of its visual base.
