Drinking tap water in Spain: is it really safe?
In Spain, tap water is officially safe and suitable for consumption, according to reports from the Ministry of Health. However, its quality varies greatly depending on the city, especially due to factors such as hardness, the content of lime, the level of chlorine or the presence of minerals that affect its taste, smell, and domestic use.
Even though it is drinkable, this does not mean it is always the most pleasant to drink or the most suitable for taking care of appliances or clothing. For this reason, more and more households choose to treat the water to improve it and adapt it to their daily needs.
