History:
One of the oldest in the world, the Vendian aquifer system gets its name from the Vendian period at the end of the Proterozoic eon (some 600 million years ago). At that time dry land was still lifeless and it was only on the floor of the muddy, shallow seas that flat water-inhabiting plants grew. Without its soil layer the earth consisted of cliffs and agglomerations of rocks. The atmosphere and the water of the oceans contained much less oxygen and greater quantities of carbon dioxide. The days were even about three hours shorter, with 420 days in the year.
Now, millions of years later, the continents and oceans have different positions. The layers of sand and clay that made up the earth’s surface in ancient times gradually sunk to a depth of many meters and became covered in layers of deposits. It is here in unique natural conditions formed over millions of years that subterranean waters purified by years of natural filtration through layers of sand are formed. The underground waters of the Vendian aquifer are maximally protected from surface pollution. The water-bearing sandstones lie on top of crystalline rocks, and all of this is well concealed from above by layers of impermeable clay. Modern man-made pollution cannot penetrate this natural shield. |
