Tailings ponds can also be a source of acid drainage, leading to the need for permanent monitoring and treatment of water passing through the tailings dam. Dry Stacking. Tailings do not have to be stored in ponds or sent as slurries into rivers. An alternative is dewatering tailings, using vacuum or pressure filters, so they can then be stacked.
