Yes, tap water in Spain is safe to drink. Over 99.5% of public tap water in Spain meets strict quality standards set by the Spanish government and the European Union, making it safe and clean. Major cities like Madrid and Barcelona have advanced water treatment systems that ensure the water is free from harmful contaminants, and the water quality is regularly tested. Despite this, some people prefer bottled water mainly due to taste preferences rather than safety concerns. The chlorine taste in some areas is within regulatory limits and used for disinfection, but it does not compromise the safety of the water. Overall, tap water in Spain is highly regarded for its quality and safety, comparable to some of the best water in Europe.
