@rostanf Thanks for caring, mate! Surprisingly, tap water from deep aquifers in most urban areas with population over 5000 is cleaner than the bottled in the Baltics. In fact, it’s among the cleanest in Europe (bacteria-wise). But yes, I only use pre-boiled water or bottled when visiting country side - unfortunately, up to 40% of shallow wells are contaminated and are not properly maintained.
