Trinkwasser vs Mineralwasser
mineral water
'Trinkwasser' and 'Mineralwasser' can both be water that you can drink. However, 'Trinkwasser' generally means water that is clean and suitable for drinking, for example from the tap or in a water system. 'Mineralwasser' is a specific type of water from a protected spring that is bottled and contains minerals. The words can be confused because mineral water is also drinkable. More precisely, though: mineral water is a product, while drinking water mainly describes whether the water is suitable to drink.
