One of the springs where Eden water is extracted are the natural underground resources in Kotuń. The spring is located in the Podlasie Region, between the Nadbużański Scenic Park and the "Bug Ravine" Scenic Park. The area is one of the most ecologically pure regions of Poland, not contaminated due to negative impact of human activity.

Because of unique location of the spring and exceptional arrangement of geological strata that serve as natural filters, Eden water drawn from deep underground flows, retains all its primeval values. It is fresh, pure and contains a naturally balanced combination of minerals.
