In 2017, Zdeněk Venera of the Czech Geological Survey stated, basing on 2015 data, that "more than twelve million cubic meters of water per year are pumped out of the mine. This can be compared to the consumption of a quarter of the population of Prague. Or with the water supply for more than three years for the population of Liberec." In the past, the Polish side also tried for a long time to undermine this argument due to the inadequate monitoring network on the Czech side, the Liberec governor, told us. In the context of the increasingly severe drought in the Czech Republic, which is likely due to climate change, as well as changes in the Czech landscape over the past two centuries, this is another example of a huge waste of dwindling natural resources of fundamental importance to nature and humans.
