How pure is iceberg ice?
The water from icebergs is actually quite pure, since glacier ice is created from falling snow, and snow results from condensed water vapour in the environment. Sometimes airborne dust from volcanic eruptions or from the wind is deposited on the surface of a glacier. Over thousands of years the dust slowly becomes trapped inside the ice, leaving traces buried inside. However, due to the location of the glaciers, you will not find many pollutants in the ice or meltwater!
