    Hence modern mining has a substantial water footprint. For instance, the production of 1 kg of mined gold consumes an average of 691 cubic metres (691 000 litres) of water. It also involves the use of highly toxic substances such as cyanide and mercury, which brings high risk of accidental releases in toxic spills from operating mines.
