“Eresfjorden is incredibly beautiful and tells a unique story. The spring water source was found through geological mapping many years ago, which also documented the quality of the water as one of the purest in Norway,” says Harald Dahl, director and co-founder of water producer Eirawater. The fjords in Norway are famous around the world for their beauty, formed by the giant glacier tongues that through several Ice Ages have shaped the landscape. “The groundwater in Eresfjorden is naturally filtered through a 10,000-year-old moraine made out of hard rock, which deposits small amounts of minerals into the water.
