Arsenic poisoning
This year's spring water wave after rains in the region reached 3-4 meters on the Arpa Dere river which flows into the Byala River. Arpa Dere is part of the eventual future mine drainage system. I've been there and was amazed by the crushing forces of water that went through the region. No matter what I cannot be convinced that such water wave will not drain the arsenic dust that will be freed from the mining process. 125 grams per ton of ore, that's 1625 tonnes of poison draining into the water
